I was watching short videos and was seen by ancient people

Chapter 133 Have you ever seen this kind of scene when you were a child? (one)

[Have you ever seen this kind of scene when you were a child? # nostalgia]

As the video begins, a person was holding a shovel and constantly stirring coal and clay. After stirring well, he put a little water in it and made it into mud.

Then he took out a tool and punched out briquettes one after another.

After the briquettes are naturally dried, they are put into a prepared coal stove when they are dry.

As the briquettes were lit, the kettle above was boiled. Not only that, but there were also people sitting next to them warming themselves up to the fire.

And there was a long pipe connected to the coal stove, which led the soot to the outside.

Qin Dynasty.

Qin Shihuang watched the video on the sky screen and was a little curious. What was that black thing?
After being mixed with earth, it can boil water and cook rice.

You must know that when he keeps warm in winter, he always burns wood. Although it is very warm, it is not as convenient as the things used on the canopy.

He felt that if there was such a thing in the hall, he would definitely make one so that he could keep warm in winter.

The Mohist disciples who were watching the sky screen video at the same time saw the black things on the sky screen, and they felt like they had seen it before.

So they rummaged hard and finally found this black thing in an inconspicuous place.

This kind of thing was obtained from their travels to Daijun (Shanxi). Although it can be burned like wood, it was collected by them.

However, because it is difficult to ignite, no one uses this kind of thing in large quantities.

They only remembered this kind of thing after seeing the sky curtain this time.

At the same time, they became curious, has this problem been solved in later generations?
So they found some soil like Tianmu, and mixed it with black things to make mud.

Then they made a tool for beating briquettes on the canopy, and made briquettes one after another just like the one on the canopy.

After waiting for a day and night to dry, they began to experiment.

I found that this kind of thing is still extremely difficult to ignite.

One advantage is that the fire is very strong after lighting it.

If you reuse the fire-burning tools on the canopy, cover the upper opening when not in use, and seal the lower opening, leaving only a small opening.

That way it could last for a long time and be convenient for boiling water for cooking, so they quickly donated this thing to Qin Shihuang.

After Qin Shihuang saw it, he praised him continuously: "Good, good, good... He is worthy of being a descendant of the Mohist family."

All the children of the Mo family were full of excitement after hearing this. After all, Qin Shihuang asked them to make a lot of things after Tianmu appeared, but they only made a very small part.

Every time Qin Shihuang called them, they felt very uneasy.

This time being praised by Qin Shihuang made them feel relieved.

At the same time, these Mohist disciples were also greatly encouraged, and they wanted to decipher more things for future generations to serve the Qin Dynasty.

Han Dynasty.

Emperor Wu of the Han Dynasty saw what was done on the canopy and quickly ordered the craftsmen to test it.

He wanted to know whether the things on the canopy could really be used to make fires for heating and cooking, as the Tianmu said.

If this is really the case, with that kang, I'm afraid people can survive in that extremely cold place.

After receiving the order, the craftsmen rushed to find coal.

Finally they got the information that there was such a thing in the iron smelting workshop.

It’s just that they are not often used, and it can even be said that no iron smelting craftsmen are willing to use them.The iron smelted from this coal is too brittle and has no room for use.

But they didn't dislike it. For them, they just needed to create the things on the marquee.

As for his specific effect?Then we need the evaluation of Liu Che, Emperor Wu of the Han Dynasty?
After a day of work, the briquette table is ready to dry.

They not only made briquettes, but also made tools for making briquettes and coal stoves for burning briquettes.

The coal stove was not made of iron like the canopy. They used brass to cast it.

The core inside is made of mud.

After doing all this, they began to experiment. After finally finding that it could be ignited, they waited for the acceptance of Liu Che, Emperor Wu of the Han Dynasty.

Emperor Wu of the Han Dynasty Liu Che saw the coal stove made by the craftsmen. He asked someone to light it. He wanted to see how the coal stove worked?Can it keep people warm in the cold winter?
At the same time, he also asked the craftsmen to think of ways to improve the coal stove so that he could use it while marching and fighting.

Especially this time to attack the Xiongnu, if we bring such a coal stove in a cold place, I believe Huo Qubing can attack more smoothly.

As the coal stove is ignited, the blue flame erupts with heat, making people feel very warm.

When Liu Che, Emperor Wu of the Han Dynasty, saw this situation, he felt that this kind of thing could be used for marching and fighting, but the structure of the coal stove needed to be modified so that it could be used better.

At the same time, he smelled the faint smell in the room, and he felt that this kind of thing could not be used in this room, or else it would put people's lives in danger.

After Huo Qubing and Wei Qing heard about it, they agreed with Liu Che, Emperor Wu of the Han Dynasty.

At the same time, they were also thinking about how to improve the coal stove so that they could use it when the general went to war.

You must know that the Xiongnu they attacked was a bitterly cold place. Apart from wars every year, the most people there would freeze to death.

Tang Dynasty.

Li Shimin and a group of ministers saw what was on the sky, and they also felt the power in it.

Now is the most critical time for them to attack Goguryeo, but as the weather changes, it becomes colder and colder.

How to survive this cold winter in this bitter cold place has become their most important thing now.

He had seen the fire pits displayed on the canopy before and thought about building some of these fire pits on the march.

It's just that the troops attacking Goguryeo were not stationed troops. They spent more time on the march and had no time to build this kind of fire kang.

And even if they get this kind of fire kang ready, they may have to set up camp again before they can use it.

As for cutting down trees wherever the march goes, it is even more undesirable.

You must know that the troops are not hundreds, thousands, or tens of thousands of troops. I am afraid that no place can withstand such consumption.

However, this thing on the sky screen is completely suitable for them.

Not only is it easy to carry, but it also burns for a long time.

Not only can they make a fire to keep warm, but they can also make a fire to cook. Is it really their best partner when marching and fighting?
So Li Shimin made a decree to have coal dug nearby and sent to the place where the two armies were fighting.

Song.

Countless readers watched the video on the marquee and were surprised that the market would use this coal.

To know about coal, there are records from the Spring and Autumn Period and the Warring States Period.

In the Han Dynasty, it was one of the materials for iron smelting.

It's just that there have been rumors among the people that using coal is easy to cause poisoning, so many people would rather buy coke than use coal.
