Seeing that Zhu Di was finally convinced, Zhu Gaochi only felt weak.

As Zhu Di learns more, many things become less and less difficult to fool as before, and more energy is needed.

I had to ponder every sentence, trying not to let Zhu Di find out the flaws, and then persuade him smoothly.

It's not easy to deal with people.

Everyone grows.

Although Zhu Di is not as good as his own understanding of industry, the speed of progress is still there, and it is difficult to make a breakthrough from scratch, but if there is a breakthrough, the progress will be very fast.

Luckily, though.

My comprehensive understanding of the industry is not something that can be deduced by a single person, but is the result of the efforts of countless people in the times.

"Today, because of the engineering team, we asked someone to say hello to your husband, and tomorrow you have to talk to your husband."

"And you also have to pay attention to fatigue, you are almost busier than us, how old you are."

Zhu Di said with concern.

That's a good point.

The stalls everywhere, although they don't do things by themselves, they can't do without their own care, and there are a lot of things together.

Everything is important.

For example, the engineering team's military households and civilian households, military households and stewards, need to run in, and they will definitely not allow accidents.

If one thing happens, all the efforts will be in vain, and we need to renew our efforts to win people's hearts.

How can you guarantee that nothing will happen? Naturally, we must be vigilant in both big and small things.

Like the matter of the widow of the engineering team some time ago, if she didn't go to the engineering team to make frequent inspections, it would be a bad thing.

It's obviously a good thing that others are grateful for, but it turns out to be a bad thing that others hate, and the result caused by a line of difference is huge.

Where are the small things and the big things so clear.

Small things can become big things, and big things sometimes become small things.

But it's definitely not as good as Zhu Yuanzhang, and if you know his daily workload, you will only sigh that it's inhuman.

As for Zhu Di.

His diligent energy is no worse than Zhu Yuanzhang's, but he is not as energetic as Zhu Yuanzhang.

Said diligent.

Zhu Gaochi remembered something.

"Father, you have been going to the middle guard and the right guard a lot recently, why are there so few left guards alone, and most of the palace's personal guard battalions are also recruited by the top two."

According to the original owner's memory, this was not the case before.

Zhu Di treated the three guards equally.

It seems to be the same this morning.

The commanders of the other two guards, whether it was Tang Yun or Chen Xian, were not only enthusiastic about their father, but also very kind to themselves.

Only Zhang Yu, who was the left guard, although he was full of smiles, always gave people a feeling that he couldn't fit in.

"Zhang Yu is a new commander, we are not familiar with him, we can't trust him, and we won't let him know about some private things, so we are naturally a little rusty."

Zhu Gaochi understood.

Even if it is Zhu Di, there are some things that can't see the sun.

For example, the spoils of last year's Northern Expedition.

Interception must be wanted, otherwise what will be used to reward the soldiers? The reward of the court could not wait, but Zhu Di hoped that the court would never be rewarded.

That's just one of the things.

The commanders of the other two guards will naturally stand with King Yan and are their own people, but who knows what Zhang Yu thinks.

What if he pokes it out?

Probably won't be so serious, but I'm not afraid of 10,000, I'm afraid of what if.

It's really poked out, and King Yan doesn't have the right to dismiss others from their positions, and he doesn't think he's unlucky.

Being in a high position, he will definitely not easily reveal his thoughts.

Zhu Gaochi shook his head.

That's not going to work.

Zhu Di's capital is already thin, and there are only three guards in hand, how can he do it without one.

It is no wonder that in the Battle of Jingjing, many heroes poured out.

The middle guard and the right guard provided a large number of talents for the Yanwang Mansion.

Half of the heroes of Jingnan came from the two guards, and the other half came from Beiping and Liaodong, but the left guards seemed a little insufficient.

Is Zhang Yu's ability not good?

Naturally not, on the contrary, this person's ability is very strong, Zhu Di even said in public, I rely on jade to help big things! Zhang Yucai is wise and brave, and he is the first to talk about Jing difficult skills.

This is very revealing.

Zhu Di has a deep control over the other two guards and knows the talents inside, but he does not have a deep control over the left guards and does not know enough about the talents.

To be exact.

Because he didn't trust Zhang Yu at the beginning, the source of the royal guards began to requisition the remaining two guards and reduce the requisition of the left guards.

This created a huge gap between the three guards in the future.

Zhu Gaochi had no way to tell Zhu Di that Zhang Yu's effect on Yan Wangfu could be trusted.

Because Zhang Yu has been in office for less than a year, he does not have a relationship with Zhu Di, let alone loyalty.

I really don't know if I can trust it now, but things haven't gotten to a point yet.

Who knows what will happen to Zhu Di and Zhang Yu in the next few years, so that this person will return to Zhu Di and be willing to rebel.

"Zhang Yu's matter, my son will find a way to solve it."

"This matter is very serious, you must not come nonsense." Zhu Di stopped solemnly.

The three guards are Zhu Di's basic plate, of course he will not give up the left guards, but the more important things he values, the more he can't be in a hurry.

I can't eat hot tofu in a hurry.

When an opportunity arises, it is convenient to contact Zhang Yu appropriately and deepen the understanding.

As the saying goes, knowing the face of the person does not know the heart.

Don't look at Zhang Yu's respect for himself now, and he never disobeys himself, but Zhu Di will not believe it easily.

Only with the precipitation of time can Zhu Di think it is reliable.

Anyway, the left guard post can't run again.

The emperor is not in a hurry, and the eunuch is in a hurry.

Seeing Zhu Di's indifference and his steady and slow appearance, Zhu Gaochi couldn't wait to pull his ear and tell him that he didn't have a few years left.

No matter how you will face the difficulties in the future as the situation develops, you should do things in advance.

For example, deepening the bond between Zhang Yu and Yan Wangfu in advance is equivalent to strengthening the control of the left guard.

This alone can increase Zhu Di's strength by one-third in the early days of the rebellion.

"Don't meddle in this matter."

Zhu Di knew that the boss was not an easily obedient person, so he warned him again.

Why is the Yanwang Mansion in Beiping, with the rise of the three divisions, it has replaced the role of the vassal palace, but it still speaks soundly?

Because he had a firm grip on the three guards.

This is mastering the barrel of the gun.

Tang Yun and Chen Xian, including the commander of the previous Zuo Guard, were both old men in the Yanshan Guard Station, and they had a deep relationship with King Yan, and they had always only listened to King Yan's orders, ignoring the Beiping Metropolitan Division and the Beiping Political Division.

Such was the case with the imperial court.

The more at the bottom, the clearer the division of rights, but the top is different, and the rights at the top are not clear.

This was especially true in the Ming Dynasty, where there was a lot of overlap in functions.

Then whoever has the loudest voice will naturally have more rights.

Yunnan's Qianguo Mansion and the Three Divisions have overlapping functions, and the two sides have competed for the entire Ming Dynasty.

For example, in the future, the cabinet was originally a Shimizu Yamen with little decision-making power, and the grade was only five grades, and gradually became the country's helm body.

However, although there is a reality, there is no name, and there is a department of authority that is more blurred than clear.

For example, the King of Qin and the King of Yan.

Both of them are vassal kings, but King Qin's current rights in Xi'an must not be compared with King Yan.

The prestige of the guard post cannot be compared.

Zhu Gaochi saw that Zhu Di's attitude was so strict, so he did not continue to be reluctant, but secretly planned in his heart.

……

The progress of road construction is slow, but when some roads are built, the speed of laying railways on the foundation is very fast.

The carriages are also made by craftsmen of Chung Hwa Heavy Industries.

As for which method to adopt, it is up to Zhu Gaochi to decide.

All of this required him to organize his thoughts, open the small notebook again, and keep writing and drawing on it.

The railway, for sure, is a four-wheeled horse-drawn carriage.

The load capacity of the four-wheeled carriage is higher than that of the two-wheeled carriage, and the Ming Dynasty Tiangong Kaiwu also recorded the four-wheeled carriage pulling goods.

But most of the ancient Chinese used two-wheeled carriages,

Because it is true that China did not invent the problem of steering the carriage, but this is not the only reason.

Many people have seized on this to prove that ancient China has lagged behind the West in history.

Saying that China's four great inventions are fake is not spread by China.

These statements were born for a simple reason.

For example, tobacco.

Japanese scholars were introduced to Luzon by the Spaniards, Luzon to Dayuan, and Dayuan to Fujian.

There are clear historical records of Li's Joseon, the West was introduced to Japan, Japan was introduced to Korea, and Korea was introduced to the Ming Nuergan, which successively won the love of the upper class in the Jurchen and the grassland, and then spread throughout the country in the Qing Dynasty.

And there is a lot of empirical evidence.

For example, the Shunyi King of the Ming Dynasty, that is, the ancient city site of the Altan Khan period, the characters in the murals in the Daxiong Treasure Hall of the Meidai Zhaolingjue Temple smoke.

The time, place, people, context, etc., all prove that the historical records of Korea are correct.

Science knows no borders, and scientists have borders.

The same is true for historians, who naturally have a position.

It's the same as Western scholars who bite Native Americans and die mainly from the plague.

Wherever the heart is, nature speaks for it.

Needham Needham, an outstanding modern British scientist and historian, pointed out in his magnum opus "The History of Science and Technology in China".

By the time of the Song Dynasty, the technological development of feudal Chinese society had reached its peak, and in many respects had actually surpassed the level of Britain or Europe before the Industrial Revolution in the mid-eighteenth century.

Three of the four great inventions of ancient China, the block printing, the compass and gunpowder, were perfected, matured and gradually introduced to the world during the Song Dynasty.

How to go to the world?

The Mongols brought craftsmen and objects to Arabia, such as the assault rifle technology invented during the Song Dynasty.

In the long war between the Arab region and the West, it was introduced to the West, and the West later produced the musket on the basis of the assault rifle.

In all of this, the steering technology of the four-wheeled carriage was not a problem in ancient China.

Not so sacred.

In European four-wheeled carriages, the rear wheels are fixed, and in the middle of the front wheels, there is an axle that can rotate freely, so that the front wheels can turn freely.

This is a matter of thinking, I really didn't expect it, and it has nothing to do with technology.

China's demand for two-wheeled vehicles is higher than that for four-wheeled carriages.

Later generations had no technical problems, and two-wheeled carriages instead of four-wheeled carriages were still popular in the countryside in the seventies and eighties.

Zhu Gaochi finalized the direction and was full of confidence.

The railroad is suitable for four-wheeled carriages.

Soon after, horse-drawn wagons carrying coal were tried on a section of the main railway, which had been repaired in advance, and various methods were tried.

On the railway, a wagon drawn by a horse with a carrying capacity of eight tons, and two horses can reach fifteen tons.

In the absence of rubber tires, there was a shock among the people.
