And now I see the use of coal in the canopy, I am afraid that it will be popular in later generations.

This made them deeply puzzled how the future generations solved this coal poison.

Then I saw that there was a long pipe on the coal-burning stove, and it really looked out the window.

They sighed repeatedly: "Wonderful, wonderful, wonderful." ”

Shen Kuo saw this structure, and he also had to admire the solution of the people of later generations.

Since burning coal in a sealed house can poison you, it would be good to expel the burning gases out of the house.

However, compared to the later generations who used iron sheets to make pipes, Shen Kuo felt that they should use bamboo to make such pipes.

This can not only solve the problem of indoor coal poisoning, but also very lightweight.

Pipes made of bamboo can even be removed when not in use.

Shen Kuo felt that such a good thing needed to be recorded in his "Mengxi Writings", and then published as a book, so that more people could know about this application method.

Ming dynasty.

Zhu Yuanzhang watched the video on the canopy, and he was slightly stunned.

Although coal has been used as one of the iron-smelting materials since the Han Dynasty, it was widely used in the life of wealthy people in the Northern Song Dynasty.

But now, coal is only like this, and it has not entered thousands of households.

This is not because the people do not know what it is for, but because it is too cumbersome and expensive to excavate.

There is also the effect of combustion, which is not as good as the carbon effect of wood burning.

Moreover, the quality of the iron smelted from coal is really poor.

And the coal dug out is more pulverized coal, which is not convenient to use.

Now after seeing the method of the canopy, I know that the people of later generations actually used coal dust in this way.

At the same time, Zhu Yuanzhang also thought of the fire kang, and he felt that the land of Liaodong.

If there is coal, no matter how hot it is, it will no longer be that bitter cold place.

Even in the north of Liaodong, those who are afraid of living there will not be afraid of the cold of winter.

So Zhu Yuanzhang gave an order for officials in Liaodong to organize people to find coal mines and dig vigorously.

He wants to let the people of Liaodong no longer be afraid of the cold in this cold winter.

……

Zhu Di saw the video on the canopy, and he felt that he needed it very much.

Although the weather in the south is much warmer than in the north, Zhu Di is used to living in the north, so he moved the capital here.

But in the cold winter, people still can't help but shiver.

Some time ago, a video of making a fire kang was played on the canopy, and he ordered someone to plate one.

I didn't expect the effect to be surprisingly good, and it can be very warm in cold weather.

Now seeing the briquettes on the canopy, Zhu Di feels that it is also very suitable for his palace.

With these things, those ministers of his are no longer afraid of the cold?

……

Zhu Houzhao saw the video on the canopy, and he remembered Wang Yangming, who was attacking Jiannu in Liaodong.

It has been more than three months since the attack on Liaodong Jiannu, although there is often news entering the capital, but he does not know the specific situation, and his heart is full of worries about Wang Yangming.

Especially the weather is getting colder and colder, and the land of Liaodong is only afraid that it will be even colder.

If there is a military operation at that time, I am afraid that the soldiers are not willing to march and fight, and there may even be a situation where the soldiers will freeze to death.

Thinking of this, Zhu Houzhao called Daniel Zhang and asked him to prepare some coal, make the briquettes, and give them to the soldiers in Liaodong.

It's just that before Daniel Zhang could act, an urgent letter from Liaodong arrived.

Zhu Houzhao opened the letter and looked at the contents, he was stunned by the contents.

That Wang Mingyang is really as Tianmu said, a saint who is rare in a thousand years.

In a short period of time, the task of eliminating Jiannu was completed, which Zhu Houzhao did not expect at all.

So Zhu Houzhao hurriedly wrote a letter and asked him to send 800 li to Wang Yangming urgently, so that he could be stationed in Liaodong, and then go to North Korea to negotiate the matter of borrowing the road.

At the same time, in order to solve the problem of those soldiers in the cold in Liaodong, he ordered the military department to purchase some coal and send it to the barracks.

After Wang Yangming saw the letter, he understood Zhu Houzhao's intentions very well.

Originally, the strategy of attacking Jiannu was what he and Zhu Houzhao thought about together, and I often heard about Zhu Houzhao's plan there, that is, to become a real general of the Japanese army.

So Wang Mingyang called the generals in the barracks, asked them to set up camp here, and even asked the soldiers to resist the cold by fire.

With only a small number of soldiers, he went to Korea to discuss with the king of Korea.

……

Zhu Youzhen saw the video on the canopy, he began to copy his homework again, and at the same time summoned Xu Guangqi into the palace.

He also wanted to hear what Xu Guangqi, a professional, thought of the briquettes cast on the canopy?

When Xu Guangqi heard the emperor's summons, he asked him to bring the briquettes that had been sealed and dried next to him and the coal stove that had just been made into the palace with him.

As he came into contact with Zhu Youzhen more and more, Xu Guangqi got to know him more and more.

This is a diligent monarch and a monarch who thinks about the people of the world.

At the same time, when he knew that he would be the king of the dead country and hanged himself in the coal mountain, he became more and more fond of copying the homework on the canopy.

And now when I see things on the canopy, I will definitely have such thoughts.

So Xu Guangqi asked Song Yingxing to make these things early, let these things enter the palace with him, and then let Zhu Youzhen evaluate them.

Zhu Youzhen looked at the things Xu Guangqi brought, and he was very happy in his heart.

He didn't expect that before his mission was released, there would be courtiers who could bring what he wanted.

At the same time, he was also curious, is this kind of thing magical in the sky?

So he ordered the guards to hurry up and light the fire to see how the stove was doing.

As the flames slowly rose, Zhu Youzhen also discovered his strengths and weaknesses.

Compared with the ondol, the biggest advantage of this coal stove is that it can cook and keep it for a long time.

However, I think that the land of Liaodong is about to be cold, but I am afraid that it will not be long before some soldiers will freeze to death because they can't stand the cold of Liaodong.

Zhu Youzhen decided to equip them with this kind of coal stove to keep them able to move normally in cold weather.

"Jiangnan: We don't burn coal, coal is toxic and easy to get into accidents, we have a lot of people there because of this, at that time we all burned firewood or firewood charcoal. 》

After Zhu Youzhen saw this comment, his heart was excited.

Although he had read in the book, if something like coal burned in a room, it could be poisoned.

But he hadn't seen it after all, and he thought it wasn't powerful.

When we saw the possibility of death, Zhu Youzhen understood the power.

So he revised the original decree before sending it to Liaodong.
