Qin Dynasty.

Qin Shi Huang, who was very happy after seeing the children of the Mo family making briquettes and coal stoves, suddenly felt that these things were tasteless when he saw the comments on the canopy.

At his time, there was no shortage of wood for fire, and briquettes and coal stoves were more icing on the cake.

Now that I know from the canopy that burning this briquette is poisonous, I must not dare to burn it again.

It's just that he is a little curious, how did the future generations use this briquette without being poisoned?

It was at this time that he remembered the coal stove that burned briquettes, and he thought it had something to do with the pipes that could exhaust the toxic gases out of the house.

So Qin Shi Huang ordered the children of the Mo family to let them get some such pipes and install them on the coal stove.

Han dynasty.

Emperor Wu of the Han Dynasty was preparing to have people build honeycomb coal and coal stoves on a large scale, and now seeing Tianmu's comment, he was a little glad that he had not given the order yet.

How to solve these problems? Like Qin Shi Huang, he wanted to know the way of future generations.

But even so, Emperor Wu of the Han Dynasty Liu Che felt that these things were worth using.

And he could let the soldiers stationed in that cold place burn coal in the kang they built.

This not only solves the problem of their lack of charcoal, but also solves the problem of warmth.

When Wei Qing saw the comments on the canopy, he was also a little glad that he hadn't used coal indiscriminately in the army.

If you really let the army use it, you will be poisoned by this coal, and it will not start with the rebellion, but I am afraid that you will be laughed to death at that time.

He remembered this comment fondly, and made people more careful when using coal.

Tang dynasty.

Li Shimin, who had already made an order to let people dig coal nearby, was a little dumbfounded when he saw this comment on the canopy.

If this coal really has such side effects, I am afraid that those soldiers will not be able to use this coal for heating.

But it was a bitter cold place, and if there was no fire to keep warm, how would the soldiers survive this cold winter?

Not only Li Shimin was troubled, but his ministers were also troubled, after all, this problem was a problem for them to attack Goguryeo.

However, the heartless Cheng Biting Jinche did not take this issue to heart, and also spread the news that he could burn coal for heating.

Regarding Cheng Biting Jin's approach, Li Shimin just sighed.

If it weren't for the side effects of coal poisoning, Li Shimin might have kept it a secret, but now that it has this effect, this coal heating is simply a chicken rib.

When the Goguryeo military commander Quan Gai Suwen heard the news from the Tang Dynasty, he laughed and said, "God help me!" With this kind of warmth, I am afraid that troops can also be stationed in a bitter cold place. ”

So Quangai Suwen gave an order to find the coal, and according to the news that came, he asked people to make the coal stove and briquettes.

He's going to have this kind of stuff in his army for the coming winter.

The Goguryeo military commander Quangai Suwen believed that with such an artifact to resist the cold, they would no longer be afraid of the Tang Dynasty's attack.

He believed that when Goguryeo survived the coming cold winter, the Tang Dynasty would no longer be afraid.

After all, Goguryeo is their territory, and it is quite easy to find this coal.

However, in the Tang Dynasty, it is not only difficult to find coal, but also it is not easy to raise food to survive the cold winter.

With the order of Quangai Suvin, soon the coal was found.

And according to the news circulated by the Tang army, briquettes and coal stoves were made.

When Izumi Gai Suwen saw the finished thing, he immediately set it on fire.

As the briquettes slowly burned, the house, which was originally a little cold, slowly warmed up.

It was only after a while that he suddenly felt that he was having trouble breathing, and he fell to the ground dizzy.

His guards heard the sound in the house and hurried in.

Seeing what was going on inside the house, his guards were dumbfounded.

You must know that Quangae Suwen is the supreme military ruler of Goguryeo, and if something really goes wrong with him, I am afraid that Goguryeo is not far from destroying the country.

So the guards hurriedly called the imperial doctor's order and asked him to hurry up and treat Quan Gai Suwen.

As for what happened in Goguryeo, Li Shimin and the ministers did not know.

On this day, while they were discussing how to attack Goguryeo, a soldier sent an urgent secret message.

When Li Shimin saw the contents of the secret report, he was a little incredulous.

He had learned about the poisoning of people by burning coal, but he had learned from the canopy.

He originally ordered people to burn coal, but he had to give another order not to let people burn this coal, which really made him lose face at that time.

Later, Cheng Yanjin spread the message that coal can be used for heating, but he did not make any indications.

However, they did not expect that a few days later, the military ruler of Goguryeo would be poisoned by burning coal, which they never expected.

So they hurriedly changed their battle plans, hoping to win some wars when the other side lost its military rulers.

At the same time, Li Shimin and a group of ministers praised Cheng Yanjin.

Song dynasty.

Countless people who read the book looked at what was said on the canopy, and they didn't feel strange.

There have been such legends since ancient times, but no one has explored them.

And the solution, they also saw in the canopy, that can completely solve the problem of coal poisoning.

And now they have learned the method of the canopy, using coal, and have found that it is really much more convenient to use than to burn wood.

Ming dynasty.

Zhu Yuanzhang saw what he said on the canopy, but he didn't take it to heart.

As for the side effects of coal poisoning, their people found out, and according to the wisdom of their predecessors, they solved coal poisoning.

And he also saw in the canopy how the people of later generations solved coal poisoning.

And as for the solution to this coal poisoning, he also found his ministers and asked them to promote it throughout the country.

However, just as he was giving the order, he saw this comment under the canopy.

"Swaying Maomao: Remember to add some lime, lime, lime to honeycomb coal!" [Wit]. 》

Clams: Why? 》

"Swaying Maomao: Removing sulfur and other toxic substances, and the iron trained in this way will not be so brittle [oh buy awkward]. 》

This?

I never thought that there was such a solution to coal poisoning.

It's just that he doesn't know, does this workaround work?

So Zhu Yuanzhang asked people to call craftsmen and let them test it.

After a while, the experimenters began to give their own results.

Although the briquettes produced by adding lime will greatly reduce the harmful substances, it does not mean that people will not be poisoned.

It's just that compared to the previous chance of poisoning, it will be greatly reduced.

In Zhu Yuanzhang's view, if you cooperate with the long chimney, you are afraid that people will be in the room where briquettes are burning, and you don't have to be afraid of poisoning.
