Since the accident in June, Ma Zhicai has learned from the pain and put all his energy into improving the train.

From carving the globe, to making the first lathe of the Ming Dynasty, to studying the connecting part of the waterwheel transmission, Ma Zhicai is already the top mechanical expert in the Ming Dynasty.

In the period of the first industrial revolution, many inventions and creations were actually separated by a layer of window paper, and the application of many new technologies was mainly a matter of thinking.

But Ma Zhicai is different, he has rich experience, coupled with Zhu Zhanji's "guidance", so that he can reach a depth far beyond ordinary inventors.

His Highness said that the wheels of the train need to be enlarged, so then enlarge.

His Highness said that the wheels of the train need to be linked, so study the linkage device.

Although he is now a member of the Ministry of Labor, in fact, he is the person in charge of the Xiamaqiao Machinery Research Institute, just like Zhu Zhanji's personal expert.

He doesn't pay attention to the identity of the outsider now, let alone a outsider, even if he is a secretary of the Ministry of Industry, what can he do?

When His Royal Highness ascends the throne, he is a mechanical expert in front of the emperor, and this identity is far more enviable than other identities.

In the past two months, he has been actively discussing with the craftsmen of various workshops to solve the problems of his brother encountered in his research.

From the melting of pure steel in the smelting workshop, to the test of mud molds, wax molds, and steel molds.

The problem of bubbles in the molten steel alone bothered Ma Zhicai and those technicians for half a month.

He is also an experienced blacksmith who proposed a breathable design, and designed two more breathable holes on the grinding tool, so that the molten steel can be fully breathable when it enters the mold, so as to solve the air bubbles in the wheel casting.

Originally, it was only a 20-centimeter diameter wheel, and such a casting does not need too precise molds to obtain a wheel casting with sufficient strength.

But when the diameter of the wheel is doubled and a half times larger, and the weight is increased by six or seven times, such a large steel casting has far more details to solve than a copper casting.

Finally, the strength of the wheel can be cast, in addition to the power part, the size of the lathe, the grinder, and the size of the fixture must be improved according to the size of the wheel.

In addition to these, there is also the part of the train that also needs to be carefully studied.

In the beginning, the wheels of the train carriage did not require power transmission, so a row of wheels was mounted on the bottom of the carriage and mounted on the rails.

These wheels are like the small wheels underneath the minecarts of later generations, they are all independent and can only change direction according to the rails.

But now that the small wheels have been changed to large wheels, Zhu Zhanji has asked the wheels in the same position in the two rows to turn in a unified manner, which can increase the stability of the cabin.

This technology does not require active control, it is just a passive adjustment, so you only need to add a joint part to the wheel axle to connect the wheels on both sides.

This technique is not difficult, it is much simpler than the manufacture of wheels, and it is designed earlier than wheels.

After more than two months of problem elimination and solving, the second test run was placed on August 14, which was also specially designed to welcome the Mid-Autumn Festival the next day.

On this day, Zhu Zhanji was unable to witness the operation of the train at Xiamaqiao Farm because he had to receive the three kings from Nanyang Sulu, Huang Yuanli and Huang Yuansun from Boni Kingdom.

After three years in the Sulu Kingdom, the Eastern King Batu Ge Lang Hara has passed away, and in the original history, he died in Texas when he returned to the Ming Dynasty and returned to the Sulu Kingdom.

Then, he was buried in Texas, and left his descendants to guard the tomb and integrate into China.

But in this life, because Zhu Di was going to the West, they did not come to the Ming Dynasty for Hajj, and when Zhu Di went to the West, when he passed through Sulu, the king of the East was already dead.

Zhu Di directly canonized the prince of the East Wang, Du Ma Han, as the new King of the East, and accepted the surrender of the Sulu Kingdom.

This kind of acceptance is not simply canonized, but the acceptance of the Sulu State as the territory of the Ming Dynasty, and the appointment of officials to the Sulu State to administer it.

The main reason why they are willing to surrender is that they want to settle down, be protected by the Ming Dynasty, and then let the people live a good life.

After the Ming Dynasty accepted them, he not only had to appoint officials, but also exported technology to them to help them improve their living environment.

They all saw the changes in Luzon, and the original Luzon had strong winds for half of the year, which was far inferior to the quiet Sulu country located next to the equator.

But now Luzon, under the leadership of Xu Chaelao, is developing better and better, and has left Sulu far behind, so they are a little anxious now.

After arranging the affairs of the country, the three kings, together with their families, came to the Heavenly Mansion to ask for support on the spice ship of the inner eunuch.

And Bo Ni Kingdom is different, they have already requested to attach the Ming Dynasty in the seventh year of Yongle, and Zhu Di at that time also agreed.

However, the old king Huang Sen died in Yingtianfu, and the two kings fought each other for several years, and then Huang Yuansun, Sharif Ali, took power from his heart to the Ming Dynasty.

Huang Yuansun was bent on attaching himself to the Ming Dynasty, but his brother-in-law, Sharif Ali, had concerns and dragged it out until now.

When Zhu Di passed through the Boni Country, he did not stay because of time, which made Sharif Ali and Huang Yuansun a little panicked.

They then followed the fleet to Star City to plead guilty, but Zhu Di didn't have them in his eyes, and pushed them back to Zhu Zhanji.

Zhu Zhanji of the Boni Kingdom must be won, just for the sake of the high-quality oil there, Zhu Zhanji will not let go of this place.

In the whole East, where high-quality light oil can be produced, and is easy to extract and transport, the only place is Bomud Country.

On the island of Sumatra, there are one of the largest oil fields in Asia, and in Siberia, there are also huge oil fields. But don't talk about those places, even Daqing, where the oil is pumped out, how can it be transported?

Only the oil quality of Bo Ni country is the best, and it is by the sea, which is the most convenient for both production and transportation.

Zhu Zhanji had some concerns about these two countries wanting to belong to the Ming Dynasty, and the main reason was not anything else, but that they had been green.

After the Arabs developed in the eighth century, they began to green, especially after their country was occupied by the Turks, and as they fled to Southeast Asia, they began to dye Southeast Asia green.

Especially in the past 100 years, because of the shrinking power of the Mengyuan Dynasty, their development has been very rapid, and Zhu Zhanji has already discovered this serious situation when he went to Southeast Asia three years ago.

Therefore, we must not treat them with preferential treatment directly like we did with Luzon and Star City, but we must have conditional help.

On 14 August, Zhu Zhanji consulted with them in the palace for a whole day, and on the surface he was very kind to them, but behind the scenes, he asked the cabinet to formulate a strict policy of religious belief in order to deal with their subordination.

If you want to become a Ming person, you can, but you must follow the customs of my Ming Dynasty, and all the rules and regulations of the Green Sect have been abandoned by me.

Otherwise, even if I want to win you over, I will only have limited help.

Whether it is ironware, shipbuilding, or trade, it must be greatly discounted.

Before this policy is formulated, Zhu Zhanji wants to dry them.

But they didn't notice the indifference behind Zhu Zhanji's intimacy, because they had been dazzled by the prosperity of Ying Tianfu.

Ying Tianfu has become the window of the Ming Dynasty over the years, and this rapidly developing city has amazed everyone who arrives for the first time.

Even those merchants and scholars from other places will be lost in this world of flowers when they come to Yingtianfu, not to mention these Yiren who have never seen the world.

The dazzling array of goods in the market, all kinds of novelties that do not know the purpose, and the miracle-like industrial area all make these people feel as if they have come to an alien planet and see the prosperity of the Ming Dynasty.

"Now that the Mid-Autumn Festival is about to pass, and then it will be the autumn season, you Aiqing will stay in the guest house of Honglu Temple for a few more days, and stay until the end of the month, and you will take time to meet you. Ma Aiqing, you Honglu Temple has to entertain several lords, don't slack off. ”

"Obey ......"

Several state lords also know that if Zhu Zhanji wants to come up with a set of policies against them, it will take a while, and it will be fast for him to come up with it in half a month.

They said goodbye one after another, and they couldn't wait to go to the market to buy a big deal.

After they were sent out of the temple, Zhu Zhanji turned back to Xie Jin and Jianyi and said: "The problem in Nanyang is the problem of religion, although I don't want religion, I can't let any religion have too much influence. So, in this regard, there must be a strict system.

Of course, in addition to the strict system, it is necessary to establish a mechanism to attract people away from religion. For example, the people who believe in the Green Religion cannot receive assistance from the Ming Dynasty, and the workshops opened in Nanyang cannot recruit the people who believe in the Green Religion.

For these lords, those who believe in the Green Religion will be halved in aid, and worship will be strictly prohibited. ”

Jian Yi had never been to Nanyang and did not understand the situation there, so he agreed very much with Zhu Zhanji's decision. But Xie Jin knew very well that most of the people in the Nanyang region believed in the Green Religion.

Zhu Zhanji's decision will definitely be resisted by them.

Among the three kings of Sulu, the most powerful eastern king Du Ma Han can be said to be Zhu Zhanji's person, and the other two kings can't make a splash.

However, the Sultan of the Bo Ni Kingdom, that is, Huang Yuanli's husband Sharif Ali, he was an Arab, and he had come to Nanyang as a missionary earlier.

He has always had concerns about Da Ming because of his beliefs, and such a policy is obviously unacceptable to him.

Zhu Zhanji said with a smile: "It's okay, reveal Lone's meaning to Huang Yuansun, if the other party is obsessed, Lone doesn't mind changing Huang Yuanli's son-in-law, or simply let Huang Yuansun be the only lord of the country." ”

The Bo Ni Country is just a small country, not to mention the western expeditionary army, just send the naval fleet stationed in Star City over, and you can directly pacify them.

At the Great Court Meeting of the Mid-Autumn Festival, on this day, no political affairs were dealt with, but envoys from various countries were invited to celebrate the Mid-Autumn Festival together in the Fengtian Temple.

In the afternoon, various celebrations were held in the palace, and Concubine Zhang, who had not come out for a long time, also let several opera troupes in the harem perform various programs for the palace attendants, palace maids, and members of the royal family.

Zhu Zhanji did not participate in the celebration in the afternoon, but in the evening, he also accompanied his group of children.

The next day, after lunch, he came to the Xiamaqiao Farm and let the train conduct another experiment.

This time, he found another problem.

After the train changed to big wheels, the stability was much improved, and it was very smooth to sit on, but when cornering, because of the shock absorption, the roll was still a bit serious.

But it wasn't a big problem, but when he sat on the car, he realized that the train was too narrow.

When designing the rails, Zhu Zhanji required a width of one meter and a half, but one mile in the Ming Dynasty was about 560 meters, divided by five hundred, and one meter was one meter in later generations.

In other words, the current track width, if it is left in later generations, is one meter six and five, which belongs to the absolute broad-gauge train.

There is also a reason why the design is so wide, because later generations based on the width of trains from the West, at the end of the twentieth century, in fact, could not meet the transportation demand.

When the train was first invented, the rails were determined by the width of two horses, and there was no scientific basis at all.

But when the railroad tracks are fully rolled out, it is too late to change.

Therefore, the width of the train track in later generations is going to be wrong.

Because the rails are designed this way, the trains are designed this way, including the tunnels, to increase the width of the trains, the entire railway line needs to be changed.

But train transportation can't be stopped, so it can't be changed at all.

Such a width is able to cope with the use for a long time. However, science and technology are developing, industry is developing, and later generations have created many giant industrial equipment, which cannot be transported by train at all.

To give a simple example, the generator sets of hydropower stations, the shells of rockets, and the fan blades of wind turbines cannot be transported by rail, but can only be transported by car.

Zhu Zhanji was born in the 70s of the 20th century in his previous life, and when he was sensible, it happened to be the period of great development in the 90s.

At the time, newspapers and television often discussed the problem that the width of the train was too narrow, which made it impossible to transport large industrial components. At that time, many people had suggested that extra-wide railroad tracks with a width of two meters should be built.

The width of two meters is a bit exaggerated, because it is a huge waste of resources, after all, there are not many such large components.

At that time, he was curious, and he also studied the gauge and transportation of trains. It was found that the track width of the train can be increased by more than one meter by more than one meter, which does not require a two-meter gauge, but only one meter and six meters of gauge.

Therefore, when Zhu Zhanji was designing, he asked Ma Zhicai to build the track according to the width of 1.5 meters (actually 1.65 meters).

But because they didn't say it too clearly at the time, when Ma Zhicai and they designed the carriage, they actually designed the carriage to be as wide as the rails......

After Zhu Zhanji sat in a circle, the train stopped smoothly, and Zhu Zhanji made two demands. "You Aiqing have worked hard, but after sitting alone, I found two big problems, the first is that the carriage is too narrow, so that there will be a lot less cargo and people. The width of the carriage can be more than one meter wider than the rails, and according to Gu's estimate, even if the width of the carriage is more than three meters, it can still remain stable.

Secondly, it is too dangerous for the braking system to rub against wood, so that in case of emergency, it cannot be stopped in time. Since the steam engine can supply power to propel the train to move, it can naturally also supply power and lock the wheels to death.

Therefore, we also need all Aiqing to work together to develop the corresponding braking system. ”

Ma Zhicai bowed down and said, "Your Highness, if the train is designed to be too wide, it will be too heavy, and the power will be slightly insufficient!" ”

"Then study a new type of steam engine, a larger steam engine, the technology will develop, and in the future it may be possible to build a locomotive that can drive dozens of carriages, and can pull thousands of people thousands of miles away at a time. The momentum of the present should not be neglected for the future. Any design should be forward-looking. ”

Ma Zhicai hurriedly said: "The minister will arrange manpower to improve,...... Then the initial design of the carriage is three meters? ”

Zhu Zhanji couldn't help but feel anxious about his dead brain, but he also knew Ma Zhicai's hardships. He only dared to do what Zhu Zhanji told him, otherwise, if there was an accident, he would not be able to bear this responsibility.

In later generations, the width of the carriage was three meters with a track gauge of one meter and four, and now with a width of one meter and six five, the carriage can be designed to be more than three meters five.

Zhu Zhanji said: "For the time being, I will be able to design the carriage according to three meters five, so that I can seat more people and load more goods." In addition......"

He looked at Jia Cong, the director of the Ministry of Engineering, who was in charge of the track research, and said: "Although the train has not been fully designed, the construction of the track in Yingtianfu can now begin. You contact the Yingtianfu Renovation Department of the Ministry of Industry to lay the rails according to the design of the new Yingtianfu.

When laying rails, remember to leave a total width of 5 to 6 meters on both sides. Protective measures should also be set up along the way to prevent ignorant children from being hit by cars. ”

With the current technical means, of course, it is possible to build a viaduct, but it is too expensive and meaningless.

As long as there are some simple protections on both sides of the tracks, such as a low wall on both sides that can block the wheels, it can be effective. As for those bear children who are looking for their own death, this cannot be avoided at any time.

Zhu Zhanji wanted to make use of the train operation in Yingtianfu to accumulate experience and prepare for the future construction of domestic railways. This tram system is destined to be replaced by trams in the future.

After the affairs were handled here, I was just about to go back when I met Sun Xian and Lan Yan together.

Lan Yan has been busy cultivating penicillin during this time, but because Zhu Zhanji did not allow her to go deep into the front line, the others had no experience for the first time, and until now, they have not been able to cultivate a large number of penicillin bacteria.

A little bit of penicillin bacteria was produced, and after a few experiments, it was gone.

Looking at Lan Yan's somewhat haggard face, Zhu Zhanji couldn't help but say: "Don't be in a hurry about this matter, don't put yourself in it because of research." ”

Lan Yan wanted to speak and stopped, Sun Xian couldn't help but cover her mouth and laugh, and said softly: "Your Highness, Lan Liangdi's energy is not good, but it is not because of the experiment, but because of the concubine, she is happy again." ”

Zhu Zhanji paused for a moment, and the first thing that came to mind was that she was pregnant, and many studies were about to stop.

However, he quickly adjusted his mood and smiled: "This is a good thing, in the future, you will only do theoretical guidance, and let others study everything on their own." Aifei is five months pregnant, why did she come to the farm today? ”

"His Royal Highness handed over the pinyin to the concubine, and now it has been basically sorted out, and today I came to listen to the comments of those Yi people. As soon as he arrived at the farm, he met Lan Liangdi fainting, so he first escorted Lan Liangdi to His Royal Highness, and asked His Highness to discipline him well, so as not to hurt his fetal gas because of his work. ”

Since Zhu Zhanji told Sun Xian that Lan Yan was the reincarnation of Doumu Niangniang, Sun Xian was extremely polite to Lan Yan, and rarely put up the shelf of Concubine Sun in front of her.

After seeing Lan Yan's current unfathomable nature, her attitude changed greatly, and she was even more cordial to Lan Yan.

She knew very well that the stronger the mysterious aura on Lan Yan's body, the less threatening it would be to her, because the crown princess would not allow a goddess to become the master of the harem and threaten her status.

Lan Yan didn't have Gong Dou's mind, his attention was on the outside of the palace, and his presence in the harem was even lower.

Therefore, Sun Xian likes her very much now. A Liangdi, who is second only to her identity, and a backstage like Princess Shu, will not become a threat to herself, but will only become an arm help, how can she not like it?

Zhu Zhanji glared at the blue smoke, which made her lower her head a little weakly, and then said to Sun Xian: "After Concubine Ai has familiarized those Yi people, you can summon Master Xie, he is more proficient in these." ”

Sun Xian nodded and smiled: "You don't have to worry about it." The two sons of the Xie family are now in Qiuqiu, and when they finish the exam, they will come to help me. ”

From the very beginning of Arabic numerals, to punctuation, and foreign arithmetic, it is all Xie Jin's promotion. Xie Zhen period and Xie Zhen Liang they are more receptive to new knowledge.

So when he heard Sun Xian say that there was already an arrangement, he no longer worried about this matter.

took Lan Yan into the carriage, and Lan Yan squirmed and lay in Zhu Zhanji's arms to be coquettish. "I didn't know that I was pregnant, so today's accident happened, so don't blame those chamberlains, palace maids."

Zhu Zhanji stretched out his hand and slapped her buttocks lightly, and said, "If you weren't pregnant, I would have taught you a good lesson." In this era, only the reproduction of children and grandchildren is the biggest thing, if you have fetal gas because of research, if the mother concubine punishes you, I can't speak. ”

"Got it." Lan Yan raised a little face in his arms and said, "I want a son, and you will train him to be as strong as you in the future." ”

"Definitely!"

Before the carriage entered the city, there was a commotion, Zhu Zhanji opened the curtains, and saw that the two soldiers of Yulinwei said something to Liu Wan, and Liu Wan ran over quickly.

"Your Highness, there was an accident in the Jiajiang Industrial Zone, an explosion occurred in the steel plant, killing and injuring dozens of people."

Zhu Zhanji thought for a moment that he had misheard, and in his impression, there was a high possibility of an accident at the steel plant, but the explosion ...... Is there something exploding there?

"What exploded?"

Liu Wan didn't know, so he could only wave to the two soldiers who reported the news, and when he asked, he realized that the heating room had exploded.

Zhu Zhanji looked at the time and instructed: "Let the person in charge of the internal supervision and the Ministry of Engineering give me the rescue of the wounded in time and send people from the hospital over." I'm going to hear from them tomorrow. ”
