On the outskirts of Nanjing, the steam engine locomotive test site.

The sky shone with a soft morning light, and across the vast field, a railroad track stretched like a dragon, shimmering with a cold metallic sheen.

This was the third day after the crown prince Zhu Gaoxu resigned from his post as a supervisor of the state, and before the impact of the incident had been fermented, civil and military officials gathered together again.

Their eyes were focused on a strange machine at the end of the tracks.

Today, they will witness an unprecedented miracle.

——The first steam engine locomotive track experiment of the Ming Dynasty.

The air is filled with the unique smell of soot mixed with a certain lubricant, a fragrance unique to the industrial age and a herald of the dawn of a new era.

The locomotive sits silently on the railroad tracks like a massive steel monster, its body made of swarthy boilers and shiny steel pipes, which is as rugged as it is mysterious.

Artisans weave around the locomotive for a final check, their faces solemn and focused, as if performing a sacred ritual.

The atmosphere was tense and solemn, as if the air was filled with anticipation, and the royal family, nobles, and civil officials gathered on both sides of the tracks, their eyes locked on the locomotive.

The audience whispered and discussed whether this never-before-seen steel behemoth would be able to run successfully, some were full of anticipation, some were skeptical, but all had a look of curiosity on their faces.

And as the inspection was over, the craftsmen announced that they were ready to start, which caused the surrounding audience to stop their discussion and begin to stare with bated breath, only to hear the soft sound of the breeze blowing through the fields and the occasional birdsong in the distance.

"Woo~"

Finally, a long roar pierced the silence, it was the signal of the locomotive of the steam engine, and the sound was shocking, like the roar of a dragon and a tiger, announcing the awakening of the steel beast.

Under the boiler, a roaring flame rises, devouring coal, releasing a huge amount of energy, steam rushes through the pipes, pushing the piston to move rhythmically back and forth, and the locomotive trembles slightly, as if to gather strength for the upcoming run.

With a louder whistle, the locomotive started slowly, first awkwardly shaking a few times, and then, as if finding balance, began to accelerate smoothly, the rails trembling gently under its weight, making a rhythmic "click" sound, as if cheering, as if in amazement.

When the locomotive started slowly, from Zhu Di to the surrounding craftsmen, all of them were instantly silent, as if time had stood still, and they watched intently as the locomotive accelerated and ran on the tracks, and the expressions on their faces gradually changed from nervousness to surprise and shock.

The spectators watched in amazement as they watched as steam erupted from the cracks in the locomotive, forming patches of grayish clouds that contrasted sharply with the blue sky.

They saw that the huge steel body was running on the railroad tracks, although it only ran a few hundred steps before gradually slowing down and stopping, but these forces from the machine were enough to shock everyone's heart.

Without any human or animal power, the machine only needs to add coal and water to move continuously.

The high-level Ming officials present were not stupid, coupled with Jiang Xinghuo's prompt before, they quickly thought of the various functions of steam locomotives, these steam locomotives can not only drive things called "trains", and transport personnel and materials along the railroad tracks to all corners of the empire with high efficiency, but also can be loaded on battleships, making them run faster, and even ignore the flow of wind and water, or, directly loaded on the chariot, covered with steel armor, forming an indestructible mobile fortress.

The locomotive slowly stopped after reaching a predetermined distance, and the steam eruption gradually subsided, but its aftermath was still in the air.

The audience was silent for a moment, then erupted in thunderous cheers.

This moment will forever be recorded in history, and the steam era of the Ming Dynasty has officially kicked off.

——————

In the thirteenth year of Yongle, Yu Qian connected the three yuan and became the second person in the Ming Dynasty after the Huang Guan of the Hongwu Dynasty.

And Jiang Xinghuo rejected Zhu Di's love on the grounds of excessive worry, and returned to Xuancheng to Jingting Mountain to guard filial piety.

In Xuancheng, a small city around Nanjing, Jiang Xinghuo carefully observed the changes of the times that he had sown and cultivated with his own hands.

The opening of the world market has affected every corner of Nanzhili, and every village has joined the commodity trade system.

The reason for this phenomenon is very simple, in this era, the Ming does not need to work the potential but has not been tapped internal needs, but can be fully invested in overseas trade, the market owned by the Ming Dynasty, from the United Kingdom in the west, to Japan in the east, most of the countries in the world, have entered the trade system dominated by the Ming Dynasty, due to the successful monopoly of the export market in most parts of the world in a short enough period of time, the Ming Dynasty naturally began to accelerate the expansion of its own export industry, And this accelerated expansion made the industrial revolution begin to penetrate into every capillary of the economic giant of the Ming Dynasty.

The social class structure of the Ming Dynasty underwent a fundamental change, the fine division of labor and cooperative production mechanisms became the mainstream of economic operation, and the factories full of machines also produced far more products than in the agricultural era.

In order to pursue greater economic interests, the landlords and gentry began to join the wave of the new era half-pushed and half-on-the-spot, and changed their own land to plant cotton in part or all to meet the demand for cotton textile production.

The cotton textile industry has also seen an alarming doubling of output, and at the same time, with the gradual popularization of various types of steam engines, mechanized production has also begun to partially break through the constraints of natural geographical conditions, although it is still inseparable from water sources, but for other geographical conditions, it can be basically ignored.

Workers, who enjoyed more meat intake and wealth income than peasants, also apparently had a higher social status when they returned to their hometowns, which brought both envy or disdain from peasants and new rural modes of production.

Workers with active brains and some money saved from part-time work in their pockets returned to the countryside and turned into small workshop owners.

Thanks to the increasingly perfect cement road network in the north and south, the products of small workshops in the countryside can well supplement the upstream and downstream needs of the entire industry, and at the same time, the craftsmanship of the people in the countryside is not bad, and the remuneration that the small workshop owners need to pay is much less than that in the city.

Small workshop owners hire some kind of craftsman from the village or simply yeoman farmers who have not practiced this craft, and they specialize in making a certain product every day in the workshop. There are all kinds of things, and the export economy of the Ming Dynasty is developing so rapidly that there is a phenomenon of "lacking everything" in a short period of time.

Over time, these people working in small workshops have been transformed from small farmers or craftsmen into village workers who live on wages.

At the same time, due to the clan characteristics of many areas in Nanzhili, in the agricultural era, people would use their spare time or the agricultural slack season to spin, weave, mine and other sideline businesses according to the products near their villages under the unified deployment of the patriarchs.

After the advent of the Industrial Age, these villages naturally developed into small industrial villages employing full-time spinders, weavers, or miners through clan fund-raising.

In the towns next to the villages, where the merchants were responsible for buying the products processed in the village or selling the raw materials needed for the village's industrial production, these towns gradually evolved into towns full of workshops or primitive factories.

Jiang Xinghuo's decision to establish a cement business network is undoubtedly very wise, which allows certain regions that lack water transportation to gain the opportunity to participate in the entire economic system.

And this new form of economy, so that the countryside of the Ming Dynasty is also the same as the city, there is a clear professional division of labor, some villages are responsible for manufacturing a certain commodity, some villages are responsible for producing and providing raw materials, and some villages are responsible for producing grain prices that are beginning to pick up.

Industry began to spread widely in the countryside, and the impact was unstoppable. New ways of life, a variety of new ideas in the city, have also entered the countryside.

In Nanzhili, from the thirteenth year of Yongle to the sixteenth year of Yongle, the number of people directly or indirectly engaged in the textile industry reached one million, and the number of various types of textile machines also soared from more than 30,000 to 150,000.

However, this barbaric growth, there is also disorder and chaos, due to the fluctuation of market prices, in some periods, there will always be a considerable number of people engaged in the production of the same commodity, in addition, even the largest textile industry, the overall structure is actually quite fragmented, spinning mills, weaving mills, dyeing mills, carding mills, bleaching factories, printing factories and other factories are everywhere, and the following sub-categories of goods and raw materials are also extremely intricate in the economic system.

But in any case, this is what the times must go through, and perhaps in a few years, this phenomenon will change, the division of labor will become more specialized, and industries will begin to carry out brutal market mergers

In addition to light industry, the heavy industry sector is also developing rapidly, and the expanding demand for coal for steam engines and the gradual replacement of wood by cheap coal as the main material for heating fires have made Daming's coal production reach millions of tons.

At the same time, the pumping steam engine and textile steam engine in the mining area have also broken through the 1,000 mark, and the first freight railway from Tianjin Sanwei to the suburbs of Beijing has also been completed, although the speed is not fast, but it is of great significance.

As of the sixteenth year of Yongle, compared with the statistics of the sixth year of Yongle ten years ago, the total population of the Ming Dynasty has risen to 64331900 compared with 60608532 people, the household registration has risen from 11537928 households to 12028851 households, the grain tax has risen from 41023379 stone to 48155680 stone, the steel output has increased from 26.13 million jin to 55.05 million jin, and the fiscal revenue has risen from 21.6 million taels of silver (non-actual silver) to 39.83 million taels.

In the sixteenth year of Yongle, Daming produced about 67% of the world's total iron, about 95% of steel, about 85% of coal, and about 78% of cotton textiles.

All the countries in the world, their future development, have been involved in the Ming Dynasty's trade system, either voluntarily or involuntarily, and the entire world trade and monetary system has been dominated by the Ming Dynasty, which is an achievement that no empire has ever achieved before, not even the Mongol Empire.

And in the future, I'm afraid that except for Daming himself, no one will break this record again.

In this era, Daming was the only factory in the world, the only global freight country, the only large-scale importer and exporter, the only fleet power, and the only country with a "world policy".

This absolute advantage comes from exploration, and Daming has never stopped this exploration.

In the seventeenth year of Yongle, Zheng He's fleet, which had completed its voyage around the world, not only discovered new continents, but also brought back those high-yield crops in the Americas predicted by Jiang Xinghuo.

- Potatoes, corn and sweet potatoes.

Although these high-yield crops still need to be tested in the soil and cultivated locally, there is no doubt that the total population of Daming will slowly start to move towards the 70 million mark.

Five years later, Yongle twenty-two years.

In the first month of the year, the Tatar Taishi Arutai, who had returned most of his blood, led the army to attack Datong Town, one of the nine sides of the Ming Dynasty.

Zhu Di, who had just moved into the Forbidden City of Beijing, heard about the military situation in Datong Town, and immediately became furious, deprived Sheng Yong of his title, and transferred him to the right capital of the military capital of Beijing to stay in Xinghou, and then assembled the Beijing camp on April 3 and led an army of 100,000 out of Juyong Pass.

The Ming army took the Shenji battalion led by Anyuan Marquis Liu Sheng as the middle army, the Yunyang Bo Chen Xu Department as the left wing, and the Fuchang Bo Fang Sheng Department as the right wing.

On April 25, upon learning that Arutai had fled to the Taranamur River, Zhu Di ordered the whole army to pursue him quickly.

It's a pity that Arutai knew that the Ming army was now sharp in guns, and the Tatar department was not qualified to fight the Ming army head-on, so he decisively led the army to flee.

On June 17, the Ming army entered the Taran Namur River, and the 3,000 battalion scouts searched for 500 miles and found no trace of the Tatar department.

On July 11, Zhu Di suddenly felt unwell and continued to march on horseback.

However, Zhu Di, the Yongle Emperor who fought on the battlefield all his life, could not withstand the erosion of time after all on the way back to the army of the last northern expedition.

On July 17, the army marched to Yumuchuan to camp, Zhu Di was seriously ill in bed, and his life was like a candle in the wind, swaying.

He was lying in the imperial tent, surrounded by solemn eunuchs and attendants, and Zhu Di in the tent had a high fever, and his consciousness wandered between reality and dreams.

Zhu Di dreamed of Zhu Gaochi's appearance when he was a child, the chubby child who always ran to him with a smile, at that time Zhu Gaochi's legs and feet were quite neat, in the dream, Zhu Di took his three sons to play in the back mountains of Yanwang's Mansion, at that time he was still very young, and laughter echoed in his ears, but when Zhu Gaochi's figure gradually blurred, it was replaced by Zhu Yuanzhang's stern face.

Zhu Di was extremely frightened, he seemed to see himself standing in the gloomy underworld, being angrily scolded and beaten by Zhu Yuanzhang, unable to resist, and did not dare to resist.

was beaten by Zhu Yuanzhang in a hurry, and Zhu Di yelled aggrievedly: "Dad! Erchen's life merits, can't he clear the charge of usurping the throne?! ”

Zhu Yuanzhang was stunned, the hand holding the whip hung down, the figure gradually dispersed, tears fell from Zhu Di's eyes, he hurriedly got up, wanting to catch Zhu Yuanzhang's figure.

"Daddy! Father! Don't go! Erchen is wrong! Erchen shouldn't talk back! ”

"-Dad!"

Then, the dream changed again, and he saw Jianwen Emperor Zhu Yunwen, the nephew who had been robbed of the throne by him, but now holding a lime-stained head, standing in front of him strangely and expressionlessly.

Zhu Di wanted to shout in horror, but found that he couldn't make a sound.

He woke up from a nightmare, covered in cold sweat, but the high fever was temporarily subsided, and his spirit was much better.

Zhu Di lay in the military tent, surrounded by dim lights and heavy air.

His face was as pale as paper, his eyes were a little out of focus, and no one knew what Zhu Di was thinking.

Zhu Zhanji, who was lying next to the couch, saw him wake up, and hurriedly asked, "Grandpa, are you better?" ”

Zhu Di didn't speak, and after a long time, he said with great difficulty: "I dreamed of your father." ”

When Zhu Zhanji heard this, he was a little gloomy. Zhu Gaochi, the king of Qi, who was in charge of preparing logistics, became ill due to overwork, and died of illness in Beijing on the way to the northern expedition of the army.

Zhu Di didn't speak for a long time, he may have remembered his former glory, those days of fighting in the south and the north, those moments of majesty and domineering, but now he can only lie here, letting the disease devour his life little by little.

Zhu Di rested for a moment before continuing to speak: "Back then, in the imperial prison, the national teacher said that I was 'born in the war and died on the journey', but now I look at it, and sure enough, I don't know how the national teacher measured the moon and measured it Anyway, it is not a pity to have a lifetime with such a celestial person." ”

Zhu Di let out a long sigh, he was already seriously ill, and he was afraid that he would not be able to return to the Forbidden City in Beijing.

In the Forbidden City in Beijing, there is a testament, and there is also a copy by his side.

Now that the crown prince Zhu Gaoxu is far away in Nanjing and can't rush back to his side in time, Zhu Di knows that his time is running out, and he must make arrangements.

"Let the cabinet members who are with you call first, and then call the princes in the army after calling them."

Zhu Zhanji instructed the eunuchs outside the tent to summon people.

And Zhu Di is so sick that the Yongle Emperor, who once wore heavy armor and fought bloodily all day on the battlefield, even straightened up from the bed at this time has become a luxury.

As a last resort, Zhu Di instructed Zhu Zhanji: "Bring my knife." ”

Zhu Di did not call himself me, but said "my knife".

Zhu Zhanji took out Zhu Di's treasure knife from the knife holder and handed it to Zhu Di.

This knife is the one used by General Xu Da, Zhu Di once took it to fight the entire battle of Jingjing, and after ascending the throne, he gave this knife to Jiang Xinghuo, who used it to cut off the head of Ding Meixia, the prefect of Changzhou.

When Yongle was thirteen years old, before returning to Jingting Mountain in Xuancheng, Jiang Xinghuo returned it to him.

Zhu Di struggled to hold down the small dragon ball in the golden dragon's mouth decorated on the outside of the new scabbard, and a mechanism bounced open, revealing the mezzanine hidden in the dragon's belly, and there was only a soft yellow satin folded together.

Zhu Di took out this edict hidden in it, which was his last edict as emperor and his last expectation for this world.

Zhu Di's hand was very steady, and he opened the yellow satin, on which many words were densely written with a red pen.

But Zhu Di didn't look at this edict, just put it on the quilt and pulled out the knife in the sheath vigorously.

Zhu Di is a fighter.

"Boom!" Looking at the knife in his hand and hearing the reassuring sound of unsheathing, he breathed a sigh of relief.

Zhu Di muttered: "Immediately the Son of Heaven will die, and the children and grandchildren of future generations, even if they are not ashamed of me usurping the throne, with my current achievements, they can leave three points of awe." ”

"Grandpa, what did you say?" Zhu Di's voice was too small, and Zhu Zhanji didn't hear it clearly.

Zhu Di didn't get an answer, but he already had an answer in his heart.

He turned his head with difficulty and looked at the north side of the tent, which was in the direction of Wolf Juxu Mountain.

Zhu Zhanji held Zhu Di's hand tightly, but he didn't dare to make a sound to interrupt Zhu Di.

Zhu Di tried his best to raise his voice.

"The territory is vast, far away from the Han and Tang Dynasties! Success, outstanding! ”

This is Zhu Di's evaluation of his life.

In his life, he subdued Mobei, defeated Timur, promoted the reform of the law, governed the Yellow River, repaired the "Yongle Grand Canon", and sailed the world with his fleet, and his exploits have long surpassed Emperor Wu of the Han Dynasty and Taizong of the Tang Dynasty.

Zhu Di, the king of Yan who rebelled, may be spurned by some people as a rebellious minister and thief, but the Yongle Emperor and the era he created will only be admired by future generations.

And at this moment, suddenly, the whole sky became dark, and the imperial tent, which was not very transparent, instantly became pitch black.

- A total solar eclipse is coming.

After another moment, Zhu Di didn't speak, Zhu Zhanji seemed to realize something, he suddenly panicked, the teardrops in his eyes made his vision completely blurred, Zhu Zhanji wiped his eyes, and trembled to test Zhu Di's snort.

Zhu Zhanji's heart rose to his throat, and just when his fingers hung down and he was about to scream, he held back stiffly.

A chill rose from Zhu Zhanji's back, as if his scalp was about to explode.

Zhu Zhanji bit his lip stubbornly, and he took the edict on the quilt with his hand.

There are many arrangements written on it, and these arrangements were originally written in duplicate by Zhu Di who was worried about any accidents on the way to the north, so he wrote them in duplicate before the expedition.

These include the succession of the crown prince Zhu Gaoxu, and the enthronement of Korea to Zhu Zhanji, the king of Qi, and so on.

Zhu Zhanji's hands were trembling, he closed his eyes tightly, and when he opened his eyes again, his eyes became firm and resolute.

Zhu Zhanji sensed a great opportunity.

- No one knows what the edict is about.

Soon, with the previous summons, Yang Shiqi and Yang Rong of the cabinet came to the imperial tent.

When Yang Shiqi and Yang Rong arrived, Zhu Zhanji was already ready.

Seeing that the big seal was so bright red that it was simply a bizarre edict that had just been covered, Yang Shiqi and Yang Rong were silent and only wrote one sentence on the edict, abolishing the prince and making Zhu Zhanji the grandson.

"Your Highness, only we know now, it's not too late to turn back."

If the edict is established, after Zhu Di's death, Zhu Zhanji will of course be the rightful successor of the Ming Empire.

But everyone knows how low the authenticity of this edict is.

In addition, Zhu Di only had Zhu Zhanji by his side before he died, so he didn't have to guess what was going on.

Zhu Zhanji gritted his teeth and tried to straighten his body, his eyes were firm and powerful, and he only said three words.

"I'm not convinced."

Yes, he was not convinced.

Since he was a child, Zhu Zhanji watched his father Zhu Gaochi's hard work, and he felt that this throne should belong to his family.

Yang Shiqi and Yang Rong felt helpless, the coup d'état was not a playhouse, and now the Northern Expedition army was close to Zhu Gaoxu from top to bottom, and this holy decree was not recognized by the nobles and military ministers, and even the Yumuchuan camp could not be issued.

What's more, even if he returned to Beijing with the Northern Expeditionary Army, there were still 100,000 Beijing battalions left in Beijing.

"The British Duke Zhang Fu has always been close to my father, and so is Xu Huizu, the left governor of the military capital of Beijing, and the right governor Sheng Yong is also available! In addition, there are so many civil officials in Beijing, all of whom were protégés of my father before his death, how can he not achieve great things? ”

"His Royal Highness the King of Qi, this is a rebellion!"

Afraid that the eunuch Huang Yan, who was outside the imperial tent, would hear it, Yang Shiqi whispered to Zhu Zhanji's ear and said this sentence in an almost "low roar" way.

"The world is our Zhu family, whose rebellion did I make?"

Zhu Zhanji took the knife and put it across his neck.

"Two gentlemen, the world is at your fingertips!"

Yang Shiqi and Yang Rong are half helpless and half frightened, how can they be willing over the years?

Zhu Zhanji's action was very fast, and he knew that the opportunity was fleeting, so after winning the support of Yang Shiqi and Yang Rong, he did not hesitate to re-use the cabinet body to forge Zhu Di's edict and cover Zhu Di's heirloom jade seal.

After the edict of Yang Shiqi and Yang Rong's hands, it is much stronger than what Zhu Zhanji hastily wrote full of flaws.

This forged decree did not directly abolish Zhu Gaoxu's position as crown prince, but wrote that the crown prince Zhu Gaochu and the Song king Zhu Gaosui were summoned to Beijing, and at the same time Zhu Zhanji, the king of Qi, was granted the supreme command of the Beijing camp.

This trick is much more clever.

Directly abolish the crown prince, all the noble and military ministers of the Northern Expedition army will be fried, and if you just let Zhu Zhanji, the king of Qi, command the entire Beijing camp, considering that the king of Qi is the prince and the highest-ranking person in the army, and Zhu Di's favor to Zhu Zhanji, this order is much more reasonable.

And once you have mastered the military power, things will be much easier to do in the future, whether it is to slowly replace the key positions with your own people, or to carry out some adjustments and changes of defense, it is very reasonable.

Summoning the crown prince Zhu Gaochu and the Song king Zhu Gaosui into Beijing is undoubtedly the occasion of "inviting the king into the urn", as long as the crown prince Zhu Gaoxu is captured and killed in front of the emperor's spirit in the palace, then the throne is Zhu Zhanji's.

Zhu Zhanji's actions did not stop there, and he clearly knew that if he wanted to consolidate his position, it was not enough to rely on a forged edict.

So on the way back to Beijing, he began to actively contact the generals in the army, especially those who held heavy troops but did not favor Zhu Gaoxu.

At this time, Gu Cheng, the Marquis of Zhenyuan, had died of illness, and Zhang Fu, the British Gong, Xu Huizu, the Left Governor of the Military Governor's Mansion in Beijing, and the Hou Shengyong of Licheng, the Right Governor, were gradually persuaded by Zhu Zhanji to agree to stand on his side.

With the support of these generals, coupled with the help of Guo Zi, the civilian leader of Beijing who was originally part of Zhu Gaochi's team, Zhu Zhanji's confidence was greatly increased, and he quickly took control of Beijing and prepared for the next seizure of power.

——————

On the day of Zhu Di's death, thousands of miles away in Nanjing, Jiang Xinghuo was looking at the sky.

At this time, around him, there were Zhu Gaoxu, Xu Jingchang and Jiang Xuan, Zhuo Jing, Cao Duan, Xie Jin, Hu Jichen and other father and son, Wang Bin, Cao Song and Huikong and others were also guarding around, and Wang Yunsheng, Fan Weixing, Zheng Hanqing, He Shuliang and many teachers and prisoners of Guozijian, including students from various countries, were gathered here to witness this historic moment.

In the entire sky of Nanzhili, there were still hot air balloons of the Flying Eagle Guard led by Huo Fei and Ding Xiaohong.

No, it is not accurate to say this, to be precise, there are hundreds of hot air balloons floating on all the key contacts of the entire Ming Dynasty.

With the popularization of science, the existence of gravity in physics has been recognized by people through the torsion scale experiments that have carried out countless tour demonstrations across the country.

And the circumnavigation that has begun to become the norm has made people realize that this world is indeed a sphere, starting from Daming from east to west, and going around will still return to Daming.

As a result, many of the theoretical foundations of science have been completely destroyed, and irreversibly destroyed.

Therefore, after more than 20 years of resistance, the science of science finally completely lost its dominant position in the Ming ideological circles, while the study of mind and practice, as well as the science that matched the study of practice, gradually became the dominant science.

But the defenders of science still hold on to the last piece of high ground, that is, "the difference between science and science".

As the cosmology of science, "Reason is Divided" firmly believes that the truth of all things comes from the Heavenly Principle, and that everything has its own truth based on the Heavenly Principle.

The reason why a total solar eclipse is measured is because the principle of total solar eclipse is that when the Moon is close to the Earth and is located near the ascending or descending node between the Earth and the Sun, the Moon will completely cover the entire surface of the Sun, turning the Sun into a black disk, leaving only a golden halo.

In this case, a total solar eclipse can only be seen by people within the moon's umbra (i.e., the darkest shadow), which is usually small, only a few hundred kilometers wide, and moves fast, so the total solar eclipse lasts for a short time, usually only a few minutes.

The "Yongle Moon Measurement" is to realize the measurement of the length of the moon's umbra in the earth's shadow area in just a few minutes, so as to estimate the diameter of the moon, and then use mathematical methods to prove that the massive sun is the center of the earth and celestial bodies such as gold, wood, water, fire, and earth, so as to falsify the physical cosmology of "rational distinction".

In order to measure the length of the shadow area of the solar eclipse on the surface, Jiang Xinghuo recreated the feat of Guo Shoujing's "Four Seas Test" in the Yuan Dynasty.

Guo Shoujing presided over the "Four Seas Test" that year, set up 27 observation stations in various parts of the Yuan Dynasty, from the Korean Peninsula in the east, to the Sichuan-Yunnan and Hexi corridors in the west, and to Mobei in the north.

And Jiang Xinghuo's "Yongle Moon Measurement" this time is on a larger scale!

Jiang Xinghuo has established 4,331 observation points and 306 observation stations stretching for tens of thousands of miles in a huge area stretching from Hami in the west, to Japan in the east, Mobei in the north, and Java in the south.

Based on these observation points and observation stations, the specific position and length of the shadow can be measured by using manpower and horsepower to find out the specific position and length of the shadow in time within the two and two intervals of the first and last four observation stations illuminated by a certain section of shadow, and then through data aggregation, and then the arc of the earth's spherical surface is projected with Guo Shoujing's "arc sagittal circumcision", and the length of the moon's umbra in the earth's shadow area can be calculated.

With the accurate data of the length of the moon's umbra in the shadow area of the earth, the diameter of the moon can be measured in equal proportions, and the diameter and area of the sun can be calculated through the relationship between the earth, the sun and the moon!

In this way, the "distinction between reason" will completely disintegrate, and a new cosmology will be completely established!

"Zhuo Gong, here!" Jiang Xinghuo patted Zhuo Jing's sleeve.

Everyone wore a head-mounted dark glass glasses tied up with a rope, during a total solar eclipse, the sun's ultraviolet and infrared rays are still shining on the earth, if you look directly with the naked eye, it is very easy to damage the eyes, and at this time, it is better not to use even an astronomical telescope, wearing glasses to look at an astronomical telescope will still damage the eyes. This is also the reason why Jiang Xinghuo has established so many observation points and observation stations.

In the sky, there was a vision.

The originally bright sun was suddenly slowly swallowed up by a huge black shadow, and the sky became darker and darker.

The people of Nanjing stopped their work and looked up at the sky, but the people here were not too alarmed, and because the "Ming Pao" had already advertised, there were still many people who followed the advice of the "Ming Pao" and did not directly watch the solar eclipse with the naked eye.

Jiang Xinghuo They saw that the edge of the sun was gradually eroded by the black shadow, forming a curved arc, and as time passed, the black shadow continued to expand, and the sun's light became weaker and weaker, and the entire sky seemed to be shrouded in a huge black cloth, which made people feel depressed and uneasy.

Arutai and his men on the steppe who had just fled back to their lair were equally alarmed, and the herdsmen began to scream in horror, believing that this was a sign of the wrath of the gods and a sign of calamity, while others knelt on the ground and prayed that the gods would bless them through the crisis, while others gathered to discuss and speculate about the cause and consequences of the vision.

In all corners of the world, everyone stopped what they were doing.

Tang Yin, who was in the Jiangnan Textile Factory, took Zhao Haichuan and others to maintain order in the textile factory and prevent the female workers from panicking too much; Zhang Yuchu, who was meditating in the Qing Palace of Longhu Mountain, heard the exclamation of the Qingfeng Female Crown, and suddenly opened his sleepy eyes; Xun Zhan, who was teaching in Yunnan, looked at the sky and muttered a few strange words angrily; Chen Tianping, who was in the palace of Annan, pushed away the concubines around him and ran out barefoot; Li Zhigang, Huang Xin, Pei Wenli and others, who were having a dinner with the political envoys of Jiaozhi, invariably stopped their chopsticks; Merchants from various countries who are floating on the sea, Li Zengzhi, Wu Chuanjia, Jiang Ge, Liu Fuchun, Wang Zhenqing, Fei Fu. At this time, they were all on the deck watching this rare vision.

As the total solar eclipse deepens, the sky becomes darker and darker, as if night is falling.

In Nanjing, the originally noisy streets have also become silent, with only a few frightened cries occasionally heard.

And throughout the Ming Dynasty, there are still many people whose faces are full of fear and anxiety, and they don't know when this vision will end, and they don't know what to do.

But many more, especially those who still hold to the point of view of science, are staring at the total solar eclipse through the dark glasses they have bought.

The detailed principles of lunar measurement, including Guo Shoujing's "arc sagittal circumcision" and the geometric diagrams of the earth, the sun and the moon, have long been published in Ming Pao, and now only one initial data is needed to deduce the results.

And this data is the length of the moon's umbra in the shadow area of the earth.

At the moment when the total solar eclipse was fully formed, with a "raise fire", the fire platform of the Guozijian observation point was ignited, and the flames rose into the air.

The Flying Eagle Guard observer in the sky faithfully drew the data from the ground onto the map in his hand with a pencil.

If the viewing angle can be raised higher, if there is a space station at this time, the people inside can clearly see that in the dark shadow area of the earth, from north to south, a red line of fire has risen! And this line of fire almost coincides with the moon's umbra!

"A spark can start a prairie fire."

Jiang Xinghuo nervously clenched the hand in his sleeve.

Today, he will defeat Rigaku head-on in front of the whole world, and become one of the saints with a new and complete cosmology!

And at this moment, Zhu Gaoxu's powerful heart suddenly stopped for half a beat.

He looked to the north with a sense of feeling, and clutched his chest.

Jiang Xinghuo saw his abnormality and asked softly, "What's wrong?" ”

Zhu Gaoxu opened his mouth blankly, thought about it, and just shook his head.

"I don't know, but I suddenly feel sad."

Finally, after a short and long wait, the shadows began to fade and the sun's rays fell back on the earth.

On September 11, the 22nd year of Yongle, all the data of the "Yongle Moon Measurement" were summarized and calibrated under the joint efforts of Qin Tianjian and Guozijian.

Jiang Xinghuo open-sourced all the observation data in Ming Pao and gave the final calculation results.

- The diameter of the Sun is about 2.7 million miles, the diameter of the Earth is about 25,000 miles, and the diameter of the Moon is about 7,000 miles.

After the "Yongle Moon Measurement", the cosmology of science and the entire theoretical edifice based on it completely collapsed, and science became the only theory that correctly explained the world.

Jiang Xinghuo, whose status has equaled the "Five Sons of the Northern Song Dynasty", has also moved from the realm of sons to the realm of saints at this time.

At this time, Zhu Gaoxu was leading a mighty army, marching along the South Beijing Railway, and arrived at Le'an Prefecture north of Jinan, where it went straight to the north, all the way to Tianjin Sanwei, and then along the first official railway of the Ming Dynasty, to the northwest of Beijing.

The holy decree from Beijing was obviously problematic, and the various information that was subsequently transmitted back from the list left by the old monk showed that Zhu Zhanji was already seeking to stand on his own feet.

Under this premise, if you only bring a small number of entourage, I am afraid that you will be directly arranged by the sword and axe man under the account.

Therefore, Zhu Gaoxu did not rush to go, but directly announced his ascension to the throne in Nanjing, and then changed the name of the year to "Jingqing".

This is because at the end of the Jingyan Battle, Zhu Di's name at the beginning was actually "Yongqing", but Zhu Di didn't like the word "Qing" very much, so he changed it to "Yongle".

And Zhu Gaoxu took the "Jing" of "Jingjing" and the "Qing" of "Yongqing" and combined it into "Jingqing", which means that the world is stable and the four seas are clear, which is not much different from the meaning of "Yongle".

As for why Jiang Xinghuo also agrees with this era name, it is unknown if there is any evil taste in it that belongs to him.

After Zhu Gaoxu ascended the throne, he instead issued an order to order Zhu Zhanji, the king of Qi in Beijing, to come to meet him, but Zhu Zhanji naturally did not comply, and the two sides were already on the same footing, and Zhu Gaoxu was not afraid of seeing that the second battle of Jingjing was about to start.

The fleet was on their side, so Zhu Gaoxu began to requisition troops, and at the same time transferred back some garrisons in Japan, Annam, Champa and other countries, and recruited Zhu Gaosui, the king of Song, and his troops.

After Xia Yuanji, the secretary of the household department, allocated money and grain, and Song Li, the secretary of the Ministry of Industry, prepared all the ordnance, Zhu Gaoxu led the 150,000 troops in the south to march in person, and Zhu Neng, the prince of Chengguo, Qiu Fu, the prince of Qi, Li Jinglong, the prince of Cao, Yao Guangxiao, the prince of Rongguo, and Xu Jingchang, the prince of Dingguo, accompanied the expedition.

Because of the railway, which was able to transport supplies, the army marched along the South Beijing Railway throughout the entire journey.

The army marched from Nanjing, converged with the three guards of the Zhou king Zhu Youjiao at the junction of Shandong and Henan, and finally stopped at Le'an Prefecture, waiting for the three guards of the Song king Zhu Gaosui, who was sent by Chen Xuan, the Marquis of Pingjiang, from the coastal port of Shandong, and Jiang Xinghuo, who arrived from Nanjing after finishing the lunar surveying work, and continued to go north along the railway without hurry.

And along the way, everywhere along the way, all the Ming troops surrendered under the leadership of the general.

On September 25, the 22nd year of Yongle, Zhu Gaoxu's soldiers approached 30 miles south of Beijing.

It seems that there are still 200,000 troops in Beijing around the city, but in fact, when these troops were forced to fight by the British Duke Zhang Fu, the Duke of Wei Xu Huizu, the Hou Shengyong of Licheng and others, the battle had not yet started, and they were already demoralized, and they all defected.

Although the commander-in-chief of the three major battalions, together with Anhou Huoli Huozhen, Chengyang Hou Zhang Wu, and Anyuan Hou Liusheng, were all stripped of their official positions and placed under house arrest, the Hou Chen Mao of Ningyang, Chen Xu, and Fang Sheng of Fuchang, who led the troops below, did not mean to work hard for Zhu Zhanji. Zhu Gaoxu is not only their comrade-in-arms and friend, but also the God of Wealth who has provided them with a lot of share dividends every year for 20 years.

Zhu Gaoxu has both favors and interests, and he is also justifiable, so why should we rebel against Zhu Zhanji?

Commanders such as the British Duke Zhang Fu, the Duke of Wei Xu Huizu, and the Marquis of Licheng Shengyong could not restrain the army, so they could only flee back to the city in a hurry.

Hearing the news that Zhu Gaoxu led his troops into Beijing, Ji Gang, the commander of the Jinyi Guard who was locked up in the dungeon, was also released by his subordinates, and under the leadership of Ji Gang, the large army surrounded the Forbidden City.

Zhu Gaoxu ordered Xie Jin to write a letter of persuasion to surrender and shot into the city with a bow and arrow.

Zhu Zhanji knew that the general trend had gone, and at the suggestion of Zhang Anshi, he surrendered out of the Forbidden City.

After Jiang Xinghuo and Yao Guangxiao jointly wrote the letter, Zhu Gaoxu, who was already the victor, did not go on a killing spree, but showed his mercy and forgave his enemies.

Zhu Zhanji, the king of Qi, was demoted from a prince to a county king, and the title of King of Qi was inherited by Zhu Gaochi's second son, Zhu Zhanjun, and Zhu Zhanji's fief was changed to Ceylon.

The British Duke Zhang Fu was demoted to the rank of Xin'anbo and reappointed as the general of the expedition to the west, leading a force in the form of a "mercenary" to participate in the war that broke out between the Aries and Black Sheep dynasties.

The Duke of Wei Xu Huizu was reduced to the people, and the title of Duke of Wei was inherited by Xu Yingxu, the right governor of the Chinese Military Governor's Office, and Xu Huizu was reappointed as the commander of the Ming Army of the Propaganda Mission of Gibraltar.

Guo Zi, the secretary of the Beijing Executive Department, and Yang Shiqi, Yang Rong and other officials in the cabinet were ordered to retire.

The Jingqing Dynasty lasted for 35 years, and in the eyes of historians, the Ming Dynasty at this time was the pinnacle, and its achievements in military, science and technology, economy, culture and other fields have reached unprecedented heights in Chinese history.

During this period, the Ming Dynasty not only achieved prosperity and stability in the country, with a total population of more than 80 million, but also actively participated in global trade with its open mind and forward-looking thinking, and dominated the global trade system.

At the same time, the progress of the industrial revolution has made the accumulation of the first-mover advantage of the Ming Dynasty more and more large, countless technological innovations have been produced in the land of the Ming Dynasty, and the fleet of the Ming Army has also sailed on all the important shipping lanes in the world.

The Ming Dynasty became the first veritable global empire in history.

The Ming Dynasty's sphere of influence is so vast that in all the regions of the world where civilizations exist, there is no place where there is a non-Ming sphere of influence that can let the sun or moon set at any moment.

The sun and the moon do not set, which is the Ming Dynasty.

In Jiang Xinghuo's eighth life, death, which had been delayed for more than sixty years, finally arrived.

At the moment when his body functions completely stopped functioning, Jiang Xinghuo's world fell into a cold and dark chaos.

The familiar feeling of drowning suffocation enveloped him, until an arm, pulling him out of it.

When Jiang Xinghuo woke up in a daze, the first thing that caught his eye was a hazy white, and he blinked his eyes, trying to dispel the fog in front of him.

Gradually, the gaze began to focus, and a spectacular picture gradually unfolded before his eyes.

White, which is the color of the warship's livery.

A towering battleship stood in the Swallow Rock Military Port, its huge body shining with steel luster in the sun, the lines of the ship were smooth and majestic, and the turrets were lined up, as if it were a sleeping steel beast, and on the deck, many soldiers shouted and shuttled through it.

At this time, on the clear blue sky, a pair of two-formation propeller fighters roared by.

He saw the name of the battleship.

"Starfire".

The river breeze gently brushed his cheeks, bringing with it the salty smell of algae and the whistle of ships in the distance, and a large number of memories flooded into his mind, the Silk Wars. The cabinet of the Ming Parliament was re-elected

At this moment, the person next to him threw something on him, interrupting his thoughts.

Jiang Xinghuo's muscle memory made him subconsciously copy this thing and pull it with his right hand, and then his eyes caught a glimpse of what it was, and a memory flashed in his mind.

Thirty-three years bolt-action rifle, after the Fourth Silk War was installed by the Ming army as a standard weapon, a quarter of an inch caliber, with a knife of eight pounds and two taels, seven rounds of ammunition in the magazine, and an effective range of 1,000 steps.

The man who threw him the shackle seemed to be a little dissatisfied with his sluggishness, and a nice female voice came: "How long are you going to lie on the ground?" The battleship Starfire was captured, and the official operation was about to begin. ”

Jiang Xinghuo stood up with a thirty-three-year-old bolt and saw a familiar face

At this moment when he was stunned, the huge caliber triple main gun of the battleship Xinghuo beside him suddenly "boomed", and there was an earth-shattering sound of cannoning, and the battleship moved a certain distance, and the wooden plank road of the dock shook with it.

And Jiang Xinghuo looked along the trajectory of the cannonball, and he was also familiar with the landing point.

- Nanjing Imperial Palace.
