"This thing only needs to adjust the height of the blade edge of the scraper by adjusting the screws on the layer of the tie rod, and then every time it is pulled through the barrel, the lever moves a few microns, and it can rotate with the uniform speed of the barrel to pull out a certain degree of rifling."

"Once the predetermined width is reached, the second rifling is pulled in a different position."

"And a better firearm needs to broach the same rifling wire about a hundred times, and the more times it is pulled, the finer and more precise the groove formed."

In the Armaments Research Institute, when Zhu Youzhen looked at the manual lathe in front of him, Zhu Youzhen couldn't believe that Bi Maokang and his people could solve the rifling matter in just two months.

He pointed to the simple thing in front of him incredulously, and asked Bi Maokang:

"You mean, with this thing, you can pull out exactly thirty rifled pipes in one day?"

"Back to Your Highness, that's exactly ......" Bi Maokang, whose temples were white, had a serious face and replied, and when Zhu Youzhen hadn't reacted, Bi Maokang said again:

"Your Highness, not only that, but the drilling machine of the hydraulic drill is also a little eyebrow-raising."

"Hydraulic drills?" Zhu Youzhen looked at him.

"This is the method that Sun Shilang and Song Yuanwailang researched based on the steam engine mentioned by His Highness." Bi Maokang did not take the credit to himself, but pushed the credit to the person next to him.

"Your Highness......"

The voice of the same voice sounded, and Zhu Youzhen looked at the sound of the voice, only to see two officials in their forties, dressed in regular clothes, waving at Zhu Youzhen.

They were not as thin as Zhu Youzhen thought, but a little fat.

However, their hair and beards are neatly groomed, giving them a very reliable feel.

"Your Highness, the subordinate official is Sun Yuanhua."

The fat man on the left, who looked a little older, opened his mouth to introduce himself, and Zhu Youzhen nodded when he heard this, and looked at the younger person next to him: "You are Song Yingxing?" ”

"Back to Your Highness, it is in the ......"

Song Yingxing responded, and after Zhu Youzhen understood the two, he asked:

"Bi Shilang said that the two of you used the theory of the steam engine to study the method of hydraulic drilling, what is this method?"

"Back to Your Highness...... Sun Yuanhua's official position was slightly larger, so he stood up and said:

"Song Yuanwailang used the method of steam siphoning water power written by His Royal Highness, first filled a hollow container with the vapor evaporated by water, and then closed the valve for steam intake, and sprayed cold water on the outside of the container."

"After that, all you need to do is open the valve to get the water in, and some of the water from the bottom of the tank will enter the pipe and be sucked into the container."

"When you get here, you just need to close the inlet valve, reopen the inlet valve, and use the steam pressure to press the water out of the container through the drain valve."

"When the water in the container is emptied and filled with steam, close the inlet and drain valves and ...... again."

Sun Yuanhua explained a bunch of Ming Dynasty discourse, and Zhu Youzhen had a headache when he heard it, but fortunately, in the end, this guy added a sentence after a long speech:

"The water in the container boils into steam, and the steam is turned into pressure, which pushes the left and right sides of the container to reciprocate, and converts the up and down movement of the container into the movement of the ship's shaft, and uses this force to push the drilling bed to drill the gun."

After Sun Yingyuan finished explaining, he looked at Zhu Youzhen directly, and Zhu Youzhen listened for a long time, and finally could only pop out one sentence:

"In other words, use the power of a steam engine to drill a gun, right?"

"Did you make it?" Zhu Youzhen asked with suspicion, while Sun Yuanhua shook his head and said:

"This process is stuck in how to transfer the power to the drill machine......"

"......" Hearing this, Zhu Youzhen was a little speechless, he thought that these two people had even made a steam locomotive.

It turned out that after working for a long time, they just worked out the principle, and by the way, they made a lathe with a manual drill and a semi-finished steam engine......

If Zhu Youzhen remembers correctly, the steam engine they said should have been made by someone before Watt, and it was stuck in the power transmission like them.

But according to them, they have at least a steam engine that can be used to pump water.

Thinking of this, Zhu Youzhen asked:

"Have you ever tried this steam engine to pump water to a depth of several feet?"

"About one zhang and four feet ......" Sun Yuanhua proudly pretended, and Zhu You only felt a little chicken after listening.

But technology will always improve, so he said to the duo and Bi Maokang:

"Continue to study the matter of the drill gun and the matter of the steam engine, and I will ask the Imperial Horse Supervisor to transfer another three thousand taels to the research institute."

"In addition, more than a dozen kinds of research such as gunpowder, blast furnace, and iron smelting should not be left behind."

"Don't record it based on experience, write down all the accurate proportions and processes, name them for some devices, and write them in the format of physics and chemistry in my Yanshan textbook."

Zhu Youzhen especially explained the recorded matter, because this thing is actually one of the reasons for the opening of Chinese and Western science and technology.

In addition to this one, one of the others is the population and economic model.

Just as Magalny brought a steam machine, a cotton spinning machine, a carding machine, and a loom to Qianlong as gifts, and guessed that these gifts would surprise and delight Qianlong.

For Qianlong or the Central Plains Dynasty of previous dynasties, even if it was a Han dynasty, when they saw things like steam engines, unless they could be used for military purposes, they would not learn.

The large population represented the need for jobs, and when the products of the steam engine unleashed a large number of textile laborers, this group of people became a source of uneasiness.

The Ming Dynasty had developed to the peak of the absolute monarchy of the feudal dynasty, and Zhu Youzhen knew that it was always going to collapse, because this was something he could not stop.

However, before the collapse of the system, he will liberate enough labor to go to overseas territory, and even if the Ming Dynasty collapses, the overseas territory will still be Han Chinese.

As long as it is Han, other Han people will want to fight for it, and this is the great unification.

Other Han rulers who are also Han Chinese will fear that other Han rulers will rise up and annex themselves, so they must move ahead to annex others.

This means that as long as Zhu Youzhen can release people, it is equivalent to him raising the requirements of "great unification" and the basic situation of China.

At that time, no matter how you fight, the territory of the next Han country will not be small.

The Industrial Revolution was necessary if the majority of the population was to be liberated to go overseas.

He led alone, even if he could only bring Daming to the level of the first industrial revolution before he died, the dividends of the industrial revolution were enough for Daming to eat for a hundred years.

A hundred years later, even if the Ming Dynasty collapses, it will definitely leave a rich legacy to the new dynasty.

Thinking of this, Zhu Youzhen asked some Bi Maokang about his research on blast furnaces, metal smelting, alloys, and so on.

Of course, the most important of these are the research on gunpowder and military affairs.

One of the good news is that the mercury thunderate used to make the fire cap and primer of the firing pistol has been preliminarily researched to make the first step of mercury nitrate.

After that, as long as the mercury nitrate is reacted with ethanol, gray thunder mercury can be obtained, and then white thunder mercury can be further obtained.

As long as the mercury thunderate is manufactured, Daming can use it to prepare fire charges and acupuncture drugs for fire cap guns, and can also use it to fill detonators for blasting.

If these things are taken out, plus the lathes and drilling machines at the moment, and then the sealing problem is solved, the Ming army can get the breech-loading firing pistol two hundred years later.

With the firing rifle, the size of the 790,000 Ming army, without considering logistics, can completely bulldoze Eurasia.

But what about that......

Zhu Youzhen frowned, he thought of the internal political contradictions in Da Ming at the moment.

"Brother is in ......"

"Bang-"

Before Zhu Youzhen finished speaking, the sudden sound of artillery spread to the entire armament courtyard, making Zhu Youzhen subconsciously touch his waist.

"Your Highness, don't panic, this is Banzai watching the research of the Artillery Academy."

Bi Maokang hurriedly spoke, and when Zhu Youzhen heard it, his hand was also put in its original position.

"Let's go, let's see." After saying that, Zhu Youzhen walked towards the place where the voice came from, and Sun Shoufa and Lu Wenzhao also followed.

Seeing this, Bi Maokang said to Song Yingxing and Sun Yuanhua: "Huodong (Sun Yuanhua's self-name), the two of you continue to study, and the old man will accompany His Highness on a trip." ”

"Yes......" Sun Yuanhua and the two returned the salute, and Bi Maokang hurriedly followed the footsteps of Zhu Youzhen and others.

When Zhu Youzhen and the others came to the back door of the main hospital, they immediately saw more than a dozen artillery research students surrounded by an artillery cannon outside the back door, as well as ......

"Hooray!"

Zhu Youzhen had a gloomy face, and said to Zhu Youxiao, who was sitting under the umbrella of Hua Luo, with a strange yin and yang atmosphere, while Zhu Youxiao, who was holding a pair of binoculars, shook his wit, turned his head and put down the things in his hand, and sure enough, he saw his younger brother with a gloomy face.

"Hahahaha...... My brother is here! I expected you to come here, so I came to wait for you! ”

"Waiting for me?" Zhu Youzhen wanted to laugh when he heard this, but he didn't bother to debunk his brother's clumsy acting skills, and only after taking a few steps forward did he take a look at the distance between the artillery and the Hua Luo umbrella.

This distance, at most, is about ten paces, if the artillery is blown up......

Thinking of this, Zhu Youzhen looked at Zhu Youxiao and said:

"If my brother is curious about firearms, just pay attention to the distance, and when you observe it in the future, you will be 100 steps away from the artillery and 30 steps away."

"Haha, I know, I know......" Zhu Youxiao used a smile to hide his embarrassment, and Zhu Youzhen didn't know how, he just felt that the two were a little rusty now.

It's not relational and emotional, it's ......

It's as if there are people behind both of them, and it's a feeling that they are both enemies.

"My brother has done a good job in this armaments research institute, I have seen a lot of things, and the whimsy in it has given me a lot of ideas."

"Especially my brother urgently needs to conquer the steam ironclad ship mentioned in the chapter in the general courtyard......"

Zhu Youxiao is really addicted to shipbuilding, and now due to the problem of materials, the wooden ship is basically the limit, so he set his sights on the so-called ironclad ship.

It's just an ironclad ship, Zhu Youzhen knows that he can't do it with the current technology.

It is not difficult to make ironclad ships, with the current strength of various countries, in fact, the Ming Dynasty only needs to use the technology of riveting armor plates on the appearance of wooden ships, so that it is an iron-clad battleship.

It can even be said that if Daming insists on manufacturing, it can also be manufactured, after all, Daming also has riveting technology.

But the problem is that without power, even if the ironclad ship is built, it is useless.

The steam engine looks simple, but it can't be powered enough to run an ironclad ship for years, decades, or even decades.

This kind of scientific and technological research can even be said not to look at time, but to see if someone has the inspiration to study it at such a node.

Therefore, after clarifying Zhu Youxiao's thoughts, Zhu Youzhen smiled helplessly:

"The premise of the ironclad ship is that the steam engine must appear as the power, and if there is no steam engine to provide power, the ironclad ship is a live target at sea only with the power of the sails."

"That's not a problem, I think Bi Maokang and their research is good, maybe it won't take a few years to build it." Zhu Youxiao responded very confidently, and even began to think about how to build an ironclad ship in his mind.

"It's really that easy......" Zhu Youzhen looked at the person in front of him with a wry smile, and then sighed and said:

"That's it, if my brother can get it, just get it."

"Then I'm going to get three thousand materials first, brother, you draw me a picture for me to refer to first." Zhu Youxiao opened his mouth with interest, and almost didn't let Zhu Youzhen bite his tongue.

"I draw?" Zhu Youzhen looked at his brother with a confused expression.

"Since my brother can write the principle of ironclad ships, he should be able to draw pictures."

Zhu Youxiao showed a hearty smile, which made Zhu Youzhen speechless for a while:

"Brother first uses a wooden boat as a structure, and it is enough to wear iron armor......"

"Isn't that fooling?" Zhu Youxiao frowned, looking unhappy, obviously not wanting to fool people.

"Forget it, my brother won't say it if he doesn't say it, I think this boat should be similar to building a wooden boat, so I went back to the palace and thought about it myself."

Zhu Youxiao also knew that when his younger brother came, he probably wouldn't be able to stay in the armament institute, but he was very interested in asking to go back.

When he said this, Zhu Youzhen was also relieved, after all, it was a little inappropriate for him to drive his brother back to the palace.

"In that case, then go back with me, it just so happens that I will tell my brother about sweeping the north."

Zhu Youzhen said with a smile, but he didn't want Zhu You's head to shake like a rattle:

"No need, no need, this matter is like this, my brother arranged for me to rest assured."

"......" Zhu Youzhen frowned, he felt that his brother seemed to be deliberately avoiding military and political affairs.

"Is it because of the Qi Wang Party......"

Thinking of the matter of the Qi Wang Party, Zhu Youzhen was a little gloomy, but Zhu Youxiao stretched out his hand at this moment and pulled his hand up.

"Let's go, go back to Beijing early, and catch dinner."

Zhu Youxiao pulled Zhu Youzhen forward, he walked in front of Zhu Youzhen, and Zhu Youzhen looked at his back.

At this moment, Zhu Youzhen seems to have experienced Zhu Youxiao's perspective and feelings on the night of the original palace transfer case.

It's just that compared to Zhu Youxiao's heart, Zhu Youzhen's heart is full of tastes.

Although he has been honed, his political methods and vision, and his military ability are all first-class in the world, his experience and memory will always be those of posterity.

The feudal bloody history of Wang Sun Gongqing fighting for power and profit, killing his father and brother for the throne is not the education he received......

If Zhu Youzhen was the kind of person who would do whatever it took for the sake of power, then he would not have chosen to go to the poor mountainous areas in the southwest to become a poverty alleviation cadre in his previous life after taking the public examination.

From the beginning to the end, he just wanted the people of Daming to have enough food, warm clothes, everyone had a field, and every family had a house, and he just wanted to be friends with his brothers.

The former should have been the hardest, and the latter was supposed to be the easiest, but now he was being coerced by power while getting power.

"It's just me behind my brother......"

Looking at Zhu Youxiao's back, Zhu Youzhen couldn't help but grab Zhu Youxiao's hand, which made Zhu Youxiao turn his head to look at him, and after showing a smile, he turned his head and continued to walk outside the city.

The two brothers were very harmonious, but behind them, Sun Shoufa and Lu Wenzhao had complicated and tangled expressions.

The group had their own thoughts, but no one could see through what Zhu Youxiao was thinking.

On the way back, Zhu Youxiao did not discuss any government affairs with Zhu Youzhen, but kept chatting about the trivial matters of having just ascended the throne and shooting arrows with Zhu Youzhen at the back left gate.

These trivial things in life, Zhu Youzhen would only laugh at them in normal times, but now he listens very seriously.

Unconsciously, the carriage returned to Beijing and arrived in front of the Baiwangfu City.

"Here's it, I'll ask Sun Shoufa to send my brother back to the palace, and I'll just walk for a while."

The carriage stopped steadily, and Zhu Youzhen also spoke in an exclamatory tone, and then Lu Wenzhao opened the car door and was about to send Zhu Youzhen home.

It's just that at this time, Zhu Youxiao suddenly said:

"Brother, I have something for Lu Wenzhao to do."

"......" Zhu Youxiao's words made Zhu Youzhen and Lu Wenzhao's actions stagnant.

Zhu Youzhen glanced at Lu Wenzhao, there was a trace of worry in his eyes, and Lu Wenzhao also looked at his nose and nose.

"Let's go......" After a while, Zhu Youzhen looked at Lu Wenzhao and explained.

"Humble and ......orderly" Lu Wenzhao got into the carriage, and Sun Shoufa was still the same as before, jumping out of the carriage directly without heart and lungs, and beckoned the three guards of the imperial city who protected the emperor to drive.

Seeing this, the thousand households of the Flying Bear Guard hurriedly stepped forward to take the reins of the horse and got into the position of the groom.

With a "drive", the three guards of the imperial city and the carriage gradually drove from the snow to the imperial city, while Zhu Youzhen looked at the back of the carriage leaving, standing in the snow and not knowing what to think.

"Your Highness, what are we going to eat tonight?"

Sun Shoufa's voice sounded, breaking the peace around him, and Zhu Youzhen also looked at him.

I saw that this guy had a smile on his face, and he didn't have the courage to kill the vanguard when he was fighting, but he looked like a farmer.

"I don't know what to eat today, you find the cook in the house, order according to your taste, and I will eat with you today."

Looking at Sun Shoufa, Zhu Youzhen showed a helpless smile, maybe only people like Sun Shoufa who are straightforward and don't have much desire for power can stand behind him.

Sometimes, it's not a good thing to be too smart......

Thinking so, he, Sun Shoufa, and Tian Cewei returned to the Qi Palace.

It's just that compared to them, the atmosphere in the carriage that went away was a little weird......

Zhu Youxiao looked at the snow scene outside the window, not knowing what he was thinking, while Lu Wenzhao was sitting on pins and needles, ready to get up at any time.

The two of them did not speak all the way, and all they could hear was the sound of the wheels of the carriage pressing on the road.

Two quarters of an hour later, the carriage drove into the Donghua Gate, and Zhu Youxiao finally spoke:

"How are you going to deal with yourself?"

"......" Zhu Youxiao's words made Lu Wenzhao not know what to say for a while, opened his mouth, and quickly closed it again.

"That's the case, I don't blame you ......"

Zhu Youxiao kept looking out the window, his eyes were calm, like a pool of stagnant water, unable to set off the slightest wave.

"I am still young and in power, as long as I reign for one day, my younger brother will still be the Grand Governor, you let Huanglong and Man Gui relax their minds, don't do anything to embarrass your younger brother......"

The words made Lu Wenzhao's hairs stand up and his pupils constricted.

"How would Banzai know ......"

At this moment, Lu Wenzhao is looking back on the memories in his mind, starting from Man Gui looking for him, is there anyone else on the way? How could anyone know about the connection between Man Gui and Huang Long?

For a while, Lu Wenzhao was sure that the emperor had buried nails in his own men, but he didn't have time to react.

"My brother and I are still young, so you can rest assured."

"When you retreat, if you want to stay in Daming, I will also discuss it with my younger brother and the prince."

"If you want to go to the Qi Kingdom, I won't stop you."

"If you do something stupid, I don't care, it's all because my brother will lead the army to the battle......"

Zhu Youxiao looked out the window calmly with calm eyes, and his tone was calm.

However, after a few seconds, when Lu Wenzhao was vigilant, he slowly spoke again:

"It's just that if it really happens, my brother may find it difficult to accept it."

"You should also know that your Royal Highness the King of Qi is too affectionate......"

Zhu Youxiao's position is being threatened, and at present, even if he can directly control the three guards of the imperial city and the generals of the Han Dynasty, they are all soldiers and horses trained by Mangui.

If Mangui wants to rebel, and the slogan is still to support the king of Qi to sit on the throne, then the entire five armies will be governors, with nearly 800,000 troops, and the number of flag bearers will not be small.

It's just that in the face of such a threat, Zhu Youxiao is still calmly communicating with Lu Wenzhao.

Or rather, he was communicating with the restless generals.

He was not afraid of the generals rebelling, because even if there was a large army rebelling, as long as he ran to the Qi Palace, with the Jing Jun and the prince, and then hid in the Qi Palace, no one could help him.

He believed that his younger brother could quell the rebellion, and he believed that he could quell it very well, but at the end of the counterinsurgency, in the face of Man Gui and other generals who were promoted by his younger brother, how should his younger brother deal with himself?

Swing a knife and kill Mangui them?

If Zhu Youzhen succeeds, I'm afraid the situation won't be so weird.

He is a man, a man of flesh and blood, not a machine.

He also got along with Man Gui day and night, talking and laughing, and fighting side by side.

He also lived in Yanshan with the soldiers and horses he personally trained, laughing and laughing, and expeditioning to the Hetao......

Now that he turned his head and asked him to raise his sword to personally order the beheading of this group of former comrades and subordinates, what would he feel in his heart?

Zhu Youxiao knew very well that he was afraid that his younger brother would collapse or be depressed.

He didn't want his brother to be in a dilemma, so he chose to put down his body and communicate well with this group of generals who thought that his safety could not be guaranteed.

This kind of communication, put in politics, is simply childish and even stupid, because Zhu Youxiao exposed his bottom line and hole cards.

But the problem is that in this political struggle, no one starts the struggle because of the desire for power.

Man Gui and Huang Long are already extremely popular ministers, even if Zhu Youzhen becomes the emperor, their official positions will not change much.

One or two lords, they will normally accompany Zhu Youzhen to fight, there is no need to rebel for this.

In the final analysis, what they are worried about is the hearts of the people, and they are worried that after Zhu Youzhen leaves, their side will be purged by the imperial power.

Ancient and modern, such things have happened too much, especially a few decades ago, after Zhang Juzheng died of illness, the fate of Qi Jiguang, Qi Jimei, Qi Jiajun and other generals is like a sharp sword hanging above their heads, always alerting them.

They didn't think that the emperor would be willing to let them all go to the Qi State, just because as soon as they left, basically the entire forty percent of the existing generals of the Ming Dynasty would leave.

It's just that contrary to the expectations of Lu Wenzhao, Man Gui and others, the emperor has now made it clear that he will let them go and let them continue to take office.

After learning that his generals have a heart of disobedience and are willing to dissuade him openly and honestly, I am afraid that Zhu Youxiao can also be regarded as the first person to communicate with each other in ancient and modern times.

It's just that Lu Wenzhao is wondering whether the emperor is using a delaying strategy because he doesn't have enough hole cards in his hand, or if he has another plan.

Ancient and modern emperors have countless methods, and after paralyzing the arrogant soldiers, there are not a few cases of waiting for the opportunity to launch a thunderous blow, and Lu Wenzhao cannot be vigilant.

He tried to make eye contact with Zhu Youxiao, but Zhu Youxiao kept looking at the snow outside the window, so he couldn't do anything.

When he was in a dilemma, the carriage stopped, and Lu Wenzhao still subconsciously opened the door for Zhu Youxiao.

Zhu Youxiao glanced at him, didn't say anything, walked straight out of the carriage, and then gradually disappeared in front of Lu Wenzhao's eyes in the sound of "Long live" from the Jingjun at the gate of the Qianqing Palace.

Looking at the closed gate of the Qianqing Palace, Lu Wenzhao had mixed feelings in his heart and was very entangled.

These entanglements eventually turned into a sigh.

He stepped out of the carriage, and after taking one last look at the gate of the Qianqing Palace, he turned around and walked towards the outside of the palace.

Under the red wall and white snow, his back revealed a twilight that did not match his age, which made people sigh......
