431 A powerful tool for expanding territory

What Zhu Qi and the others made were actually heating. This thing is very common in later generations, but no one can think of it now, because this thing seems simple but has many problems that the ancients could not solve.

For example, sealing. The ancients may have no problem with making a pipe that is several feet long or even several feet long. However, once the pipe grows to a certain extent, it needs to be connected, and the sealing cannot be guaranteed.

The heating pipes are not ordinary long, and there are not ordinary places where they need to be connected. The ancients could not solve this sealing problem at all.

There are boilers, valves, etc., so don’t even think about it.

Of course, the ancients also thought of many ways to resist the severe cold.

The easiest thing is to roast the fire, that is, to cook a pile of firewood next to it, but roast the fire has many disadvantages to keeping the cold. When the fire is too big, people can't stand it, and when the fire is too small, they won't work. After a long time, people will be dry and can't stand it, and if they don't roast it, they will be cold and can't stand it. There are also problems such as Martians that can easily cause fires, and the smoke is too big and smoke is too hot to make people unable to stand it, etc.

For this reason, the ancients also thought of many ways to improve.

For example, the commonly used kang by Oriental people means using firewood to heat the earthen kang.

For example, the fireplace commonly used by Westerners is to open a hole in the wall, build a stove, and throw the firewood into it.

However, there is one disadvantage between kangs and fireplaces, that is, their limitations are too great. People cannot lie on the kangs all winter, nor can they always sit next to the fireplace without moving.

Therefore, in ancient times, the cold north was generally sparsely populated, and the more north they went, the fewer people. Basically, in winter, only those nations who adapted to the severe cold could stay. Ordinary people could not live in such a cold and frozen environment.

To be honest, Bi Maokang, Song Yingxing and others did not expect that Zhuqiu was so busy to solve this problem.

Because this is the southern edge of the Korqin Grassland, it is not the cold area that is so cold that people can't bear it. Moreover, it is not yet cold at this time, the temperature is not very low, and everyone doesn't feel that it is very cold.

However, the heating in the study was really great. Bi Maokang, Song Yingxing and others sat for a while and were sweating a little. It was just the beginning. As the steam continued to circulate, the temperature in the study was getting higher and higher, and everyone was so hot that they couldn't stand it.

The red utensil was prepared for a long time, so I specially wore two coats and took off the sable robe. It was also formal attire, and it was just right.

Bi Maokang, Song Yingxing and others were embarrassed. How could they wear two layers of formal clothes? The coat was taken off, and the underwear was inside. It would be too rude to wear underwear in front of the emperor.

Zhu Qizhao didn't care much. Seeing that everyone was sweating profusely, he couldn't help but shake his head and smiled: "Okay, okay, everyone should take off their coats, otherwise the clothes would be wet, and when the cold wind blows out, it will catch a cold."

Everyone is so embarrassed. Most people really dare not be so rude in front of the emperor. However, they have been in the relationship between Zhu Qizhuo for decades, and they are not so reserved.

The emperor said to take it off, then take it off.

Everyone took off their coats and felt much more comfortable. However, it was the first time they were so rude in front of the emperor that everyone was a little ashamed. Coupled with the warmth in the study, everyone's faces were red and they looked really funny.

Seeing this, Zhu Qizhe couldn't help laughing and said, "How is this thing? Isn't this thing more comfortable than roasting fire?"

Roast the fire?

When everyone heard this, they couldn't help but look at the curved copper tubes thoughtfully.

They finally understood why the emperor was working so hard.

It turns out that this thing is a special stove!

It is indeed much more comfortable to roast the fire like this, but it is a bit too extravagant to make such a big battle and work so hard.

The emperor was not like this before. Could it be that just because Jiannu had already fled far away and the world was already peaceful, the emperor was a little arrogant and so arrogant?

This is not possible. Those who are ministers must remind him.

Everyone looked at me, and I looked at you. In the end, Bi Maokang, the oldest qualified one, stood up and bowed: "Your Majesty, it's easy to go from frugality to extravagance, but it's hard to go from extravagance to frugality!"

What kind of frugality?

What a luxury!

Zhu Qizhu was stunned for a moment before he realized.

It turns out these guys thought he was just for enjoyment!

He said laughing and crying: "Do you think I made this thing for my own use?"

Isn't it?

That's enough. The emperor is a smart man, and everyone is silent.

Seeing that everyone was deeply convinced, Zhu Qizhi couldn't help but shake his head and smiled bitterly: "I'm not so bored. This thing is actually a powerful tool for expanding territory."

Is this a bit too much?

What is the powerful tool for expanding territory?

Could it be that you can carry the big boiler to the battlefield and burn the enemy to death?

Bi Maokang couldn't help asking: "Your Majesty, I'm brave enough to ask, can this thing be used on the battlefield?"

Zhu Qizhuo shook his head slightly and asked without answering, "Think about it, why didn't our Ming Dynasty station a large army in Nuergandusi and defend that huge territory? You must know that the territory there is so vast that it is enough to meet most of the two capitals and thirteen provinces."

Uh, this one.

The territory under the jurisdiction of Nuergandu is indeed quite vast, but the environment there is too harsh. When winter comes, it will freeze and make people feel cold. Except for Jurchens, Jirimi, Kuyi, Daur and others who live there all year round, they can withstand the severe cold there. If others go there, they will not be able to survive.

Therefore, the Ming Dynasty basically adopted the system of custody and ward stations for the Nuergandu Department, that is, appointing local tribal leaders as commanders of the ward stations, thousands of households and hundreds of households, instead of the Ming Dynasty's jurisdiction in which they were located.

For example, the Jianzhou Wei where Jiannu was located was affiliated with the Nuer Gandusi, and Nurhaci was the commander of the Jianzhou Wei appointed by the Ming Dynasty court.

The reason why the Ming Dynasty implemented the system of garrison in Nuergandushi was a helpless move, because the soldiers of the Central Plains could not adapt to the harsh environment there at all.

Moreover, due to the long journey, the transportation of food, grass and supplies from the garrison was also a huge expense. At the beginning, during the Yongle Dynasty, the Ming Dynasty had tried to station thousands of people in Trin City in the Heilongjiang River Basin. When he arrived at the Xuande Dynasty, Xuanzong withdrew all the people. There was no way, the weather was cold and the ground was frozen there, so it was really not suitable to garrison.

In this way, the Ming Dynasty's control of Nuergandusi was purely dependent on the local tribes, which was also the fundamental reason for the rise of Jiannu.

These Bi Maokang, Song Yingxing and others naturally knew that they just did not associate this thing with the garrison of Nuergandus.

If all the garrisons of Nuergandusi could be built like this newly built state government office, there were copper pipes everywhere and steam was also circulated, it would be no problem to garrison troops there.

After all, the main reason why Nuer Gandushi cannot garrison is that it is too cold. In winter, the guards basically can only stay on the kang. With this thing, it will be different. Build more sentry towers, steam, open some arrow holes, and a telescope. There is no problem standing guard and keeping guard!

Thinking of this, Bi Maokang, Song Yingxing and others all showed a look of surprise on their faces.

This thing is really a powerful tool for expanding territory. If railways and trains transport food, grass and supplies, there would be no problem if the territory of the Ming Dynasty expanded to Siberia.
