After dealing with the affairs of many small countries, Zhu Yunxi had to withdraw his hand to prepare to deal with the affairs of the Tatars.

The defeat of the Northern Yuan has been decided.

But that land in the north of the desert is too vast, no matter how brave the soldiers of the Ming Dynasty are, it is impossible to wipe out the Northern Yuan.

After all, even hundreds of thousands of pigs are placed in such a vast area.

It's not easy to catch!

Therefore, if you really want to solve the problem of Beiyuan, once and for all, you still have to put the root of the problem on Daming itself.

First of all, it is impossible to build a road similar to a national highway in the territory of the Northern Yuan Dynasty, not to mention that the cost of construction is at least ten times higher than that in the Ming Dynasty.

The maintenance and maintenance of roads alone is a big problem that cannot be solved.

Moreover, roads such as national highways are enough for the territory of the Ming Dynasty, but the land of Mobei is unimaginably wide, and it is expected to use national highways to consolidate the rule.

It's like a dream!

So if you want to completely conquer the Northern Yuan, there is only one way that Zhu Yunxi can think of.

That's to build a railway!

Although Zhu Yunxi, a steam engine that can drag a 10,000-ton train, can't solve it, the railway dragged by a horse-drawn carriage is not a problem for Daming.

Fine things can't be done by Da Ming now.

But some simple things, for Da Ming, are things that he wants to do or not.

As long as a railway that can pass through trains is erected in the territory of the Northern Yuan, and a city is poured every other distance, in this way, the Northern Yuan can be said to be impregnable.

There is no fear that the Northern Yuan will break away from the control of the Ming Dynasty.

But Zhu Yunxi did not plan to include the entire Northern Yuan in the Ming Dynasty, but only planned to collect the most fertile grassland.

And use this steppe to envelop some Northern Yuan Tatar groups.

So that they can work for Daming, after all, animal husbandry is also extremely important to Daming.

In the territory of the Ming Dynasty, most of them are mainly cultivated cattle, only in the desert, there are a lot of beef and mutton, which are rich food resources!

If only the people in the Ming Dynasty could eat meat every day, and even drink a glass of fresh milk.

It can definitely greatly improve the comprehensive physical fitness of the people of the Ming Dynasty.

It can be seen from the trajectory of later generations that after being rich in nutrition, there will be a significant increase in both height and weight.

Don't look at Westerners who are born tall and tall, in fact, in this era, there are also many short people.

Why do future generations look so tall?

All because Westerners plundered too many resources from various countries during the Great Voyage of Discovery.

It took hundreds of years to cultivate a physique step by step.

Therefore, Zhu Yunxi has never forgotten to open up his own ranch for Daming, and included part of the pasture of the Northern Yuan Dynasty into the territory of Daming, while overseas, Zhu Yunxi is eyeing the land closest to Daming, with many kangaroos.

That's the real great pasture!

With an idea in his heart, Zhu Yunxi hurriedly recruited Xu Miaojin, and it was time for the Technology Research and Manufacturing Bureau to play a role.

After all, Zhu Yunxi spends a lot of money every year to raise the eighteen squares of Jinling.

At the critical moment, you have to play a role!

Soon, a shadow came in a hurry, and it was the director of the Technology Research and Manufacturing Bureau - Xu Miaojin.

And when Xu Miaojin arrived, Zhu Yunxi was writing and painting on the table with a pen, and the palace people on the side saw that it was Xu Miaojin, and they didn't squeak.

If you change to someone else, you will inevitably have to block one or two.

Then pass on to His Royal Highness the Grand Sun.

But if it was Xu Miaojin, the palace people naturally didn't dare to stop it, after all, who didn't know that this strange woman who was famous in the capital had long been the queen of the Ming Dynasty, and maybe in a few years, she would be in charge of the harem.

At that time, Xu Miaojin will be their top boss!

Who would dare to stop it?

Isn't this wishing I had died sooner?

Xu Miaojin walked into the house, quietly walked behind Zhu Yunxi, and looked fixedly, only to see Zhu Yunxi raising a pen and drawing a carriage with a very strange shape.

The regulations are several times longer than the carriages of a normal horse-drawn carriage.

There are many wheels underneath.

Under the wheels, it is not an ordinary road surface, but a groove that fits the wheels tightly, and there are two rows of wheels with two tracks.

Xu Miaojin asked with a little curiosity, "Your Highness, what is this?" ”

Only then did Zhu Yunxi come back to his senses.

Fang Cai was so focused that he didn't even see that Xu Miaojin had arrived.

Gently putting down the pen in his hand, Zhu Yunxi turned to look at Xu Miaojin and said, "You are here." ”

Then he explained: "This is ......"

Zhu Yunxi just wanted to call a train, but after thinking about it carefully, this thing is not driven by a steam engine now, and it doesn't need to burn a carbon fire, so how can it be called a train?

But after thinking about it, is it called a carriage?

"Forehead ......"

Zhu Yunxi shook his head and said with some amusement: "This is a train!" ”

"Didn't I ask you to study the steam engine in the Technical Research and Manufacturing Bureau? In the future, the structure of a large steam engine will be studied. ”

"You can rely on the power of the steam engine to drive these carriages."

"Hence the name Train."

"But for now, you can drag it with a horse first, and then try it first."

The research on the steam engine has already been arranged by Zhu Yunxi.

After all, the principle of the steam engine is really simple, it is nothing more than boiling water, and the individual structure is also very simple and not difficult.

But the real difficulty is in the construction of large steam engines.

This involves a real blank knowledge of Daming, you must know that the power brought by a single piston to do work is very weak, and if you want to drive a train, you need many pistons to do work at the same time.

The difficulty is suddenly increased countless times.

In his previous life, Zhu Yunxi had the privilege of seeing the inner workings of some large steamships and trains.

It's incredibly complex.

After Xu Miaojin listened, he roughly understood what Zhu Yunxi meant.

Said apologetically: "The matter of the steam engine is that my Technical Research and Manufacturing Bureau is not doing well. ”

"Disappointing Your Highness."

But Zhu Yunxi just waved his hand.

Didn't pay much attention to it.

said: "It's okay, this thing is already complicated, just take your time." ”

"But it's not difficult to build this carriage and rails."

"You take it back and let the people below study it."

Xu Miaojin nodded, carefully put away the drawings, and with her vision, she could see that this thing was nothing more than a layer of iron sheet.

Iron is not even necessary, wood can be used as a substitute.

It's just that the weight it can carry is different.

But now the Ming Dynasty does not have such a large demand for transportation, as long as it can carry some soldiers and supplies, it is a big deal to send fewer things at a time.

"Alright, you can go down."

"I'll discuss with other ministers about the return of the Northern Yuan later."

"This time, at least a piece of meat will be cut off from the Tatars!"

Zhu Yunxi's eyes were full of family and country affairs.

Xu Miaojin glanced at Zhu Yunxi resentfully, sighed lightly in her heart, it was not easy to see each other, but she was about to drive her away before she could say a few words.

But after all, it's about Beiyuan.

Xu Miaojin could only take the drawings and turn around and leave.

I silently looked forward to it in my heart, if only His Royal Highness the Taisun could grow up soon.

Over time.

Xu Miaojin has grown into a girl, but Zhu Yunxi is not yet ten years old, but she just looks like a teenager.
