To make briquettes, you need to smash large coal blocks, add some yellow mud, mix them with water, and then use a baller to beat them into briquettes.

At that time, although I was still young, I basically didn’t participate in the process of making briquettes, but I had close contact with them, and when I touched the coal, my face was turned black, and my clothes were black. Then I've been beaten up.

Because of his close experience, Han Cheng knew coal well.

For this reason, when he first saw it, Han Cheng was basically able to confirm that the thing he was holding in his waist was coal!

Han Cheng took it from Yang's waist and held it in his hand to watch.

Things start heavy.

It may be that the coal rock has experienced too much wind and rain on the surface, so the surface is not smooth.

Unlike the coal mined from a mine, it shone with some luster under the sunlight.

However, judging from the gloss of the hands and the successful blackening of the hands, they can basically be identified.

Han Cheng stood here and watched for a while, then walked a few steps to the side, came to the side of a rock, and smashed the large coal rock he was holding against the rock fiercely!

"Bang~"

With a muffled sound, the coal stone immediately became torn apart.

The cracked coals scattered all over the ground.

A piece of coal fell directly to the feet of the sheep's waist.

Han Cheng's sudden move directly blinded people.

People don't know why the **** of their tribe suddenly changed his face and made such a big fire.

The excited Yangyao and others, who were still smiling and excited, quickly disappeared, and stood there as if they were stunned.

After a brief period of confusion, they thought of the reason.

The reason is that the black stone he and others brought back is not the coal that the **** child said.

If this were not the case, how could the son of God smash it to pieces?

Han Cheng didn't care about these.

At this moment, he was squatting on the ground, carefully watching the broken coal.

The broken part of the coal rock that fell apart showed a familiar appearance to Han Cheng.

In the darkness, there was some luster.

This is the most important reason why Han Cheng suddenly threw this coal rock open.

Because it suddenly occurred to him that the surface of coal rock can be weathered, but the inside will not be weathered away!

At this time, I fell open and saw that it was true.

"This is a means of inspection! Now I can basically be sure that this black stone is coal!"

Han Cheng turned his head and saw the strange expressions of everyone, and immediately said to them with a smile.

After hearing what he said, the people in the tribe suddenly became relieved and happy.

"Wait for a while, we will do the last test to completely determine if this thing is the coal we want!"

Han Cheng said so.

Although it has been basically determined that this thing is coal, Han became a precaution, so he still wants to test it again in order to thoroughly confirm whether this thing is coal or not.

This test method is very simple and straightforward, that is-burn!

...

Many people gathered near an iron stove in the Tieshan residential area, and firewood was lit in the stove.

Driven by the bellows, the firewood inside is particularly vigorous.

"Wow..."

With this sound, the flame in the furnace suddenly became much smaller.

Han Cheng, who was holding the copper shovel, stood here, looking at the black crushed stone placed in the stove, with anticipation on his face.

The brass shovel in his hand was stained with black ash.

"Increase the firepower!"

Han Cheng said, there was some excitement in his voice.

After his voice fell, the person squatting under the stove pulling the bellows suddenly increased the frequency of pushing.

Puffs of air rushed into the stove whirring.

Everyone could not help holding their breath, standing on tiptoe, craned their necks and looked into the stove.

Everyone was full of curiosity about what the Son of God was doing.

Things like stones, in their impression, have never been burnt.

Even if things like iron ore and copper ore can be melted by flames, they won't.

But now the son of God told them that a black stone like coal can burn.

Not only can it burn, but it can also burn very hard!

Such things as coal are more useful than charcoal made from wood!

Although they knew that the **** child would not be able to deceive them, they still wanted to take a look at this strange thing that was obviously counterintuitive.

See if this stone can really burn like the **** son said.

With the people pushing and pulling the bellows, thick smoke rose from the stove.

In the air, there was some familiar choking smell.

Han Cheng couldn't help but smile at the smell.

That's right.

This exudes heavy pollution, but at the same time it also represents the taste of civilization and advancement, that's it!

The sheep waist and others found coal!

While Han Cheng was waiting with a smile on his face, and in the eagerly awaited wait of the Qingque tribesmen who surrounded him, the smoke coming out of the stove became less and less, and the coal dumped by Han Cheng was overwhelming The flames started to drill out from the cracks in the coal.

And it's getting bigger and bigger.

This flame is not the same as the flame produced by ordinary firewood.

The fire from wood fire is milder.

The flames that emerged at this time did not seem to be as large and high as the flames of firewood.

However, just by looking at it, you can feel the temperature contained in it, which is far higher than the ordinary flame.

Of course, this feeling is basically only felt by Han Cheng, who has seen coal burning in iron furnaces, and later generations who used cutting guns to cut steel plates at high temperatures.

After a while, the temperature inside the stove continued to rise.

Many parts of the black coal have turned red, and it looks like Fotan!

At this time, the dry wood, which was placed at the bottom of the stove and used as a fire lighter, was completely burnt.

Only coal is left in the stove!

Such a scenario can fully prove one thing.

This thing is that what is burning at this time is the black rock and coal!

With such a scene, I saw everyone in the Qingque tribe around them, their eyes widened, and they were surprised and infinitely delighted!

This thing is really the same as the son of God said, it can actually burn!

Because of the successful burning of coal, the black stone in the eyes of the Qingque tribe, the entire Tieshan residential area of ​​the Qingque tribe became extremely lively.

Everyone was filled with joy and joy.

"...This coal was found near the Red Tiger Tribe..."

The person who came back with the sheep waist said to Han Cheng.

After learning about this, Han Cheng was taken aback for a moment.

This news is too surprising for him.

Long ago, he had thought about how good it would be if there was a coal mine in the Red Tiger tribe.

But such an idea is just thinking about it in my heart.

Han Cheng himself felt that this could not happen.

After all, there are already so many mineral resources near the Red Tiger Tribe!

With so many mineral resources gathered together, it is already very rare, he really dare not think too much!

However, he did not expect that reality would give more than he thought.

It was completely beyond his thoughts!

This Red Tiger tribe is really a treasured land of geomantic omen!

Han Cheng sighed in his heart, and his thoughts of turning the land where the Red Tiger tribe lived into his own tribe became even stronger.

Such a treasure of geomantic omen, it is really a shame not to include it in your own tribe!

"Wow..."

Such a noise once again appeared at an iron-smelting furnace in the Tieshan residential area of ​​Qingque tribe.

The iron smelter holding a handful of copper shovel shoveled the coal that had been smashed into lumps and added it to the furnace.

Then he began to pull the bellows vigorously.

After it gradually burned open and confirmed that it would not go out, then began to add crushed iron ore to it.

This is a member of the Qingque tribe, who began to try to use coal instead of charcoal to smelt iron ore.

Han Cheng thought about replacing charcoal with coal a long time ago, making it the main metal smelting fuel.

Now the tribe finally got coal.

Under such circumstances, Han Chengdu will try as fast as possible anyway.

Therefore, after thoroughly confirming that this thing is indeed coal, the tribe's use of coal instead of charcoal for smelting has also kicked off.

The wind box is pulled, the furnace fires, and the temperature in the furnace increases continuously.

Later, the orange-red flame climbed all the way along the stove, and finally came to the upper part of the stove, revealing that the stove radiated out with extremely high temperature.

Han Cheng watched all this happening around him, waiting for the results to appear...

"Bah Bah Bah..."

There was a rustle, and a burst of hot red molten iron flowed out of the stove and fell into the earth trough below...

Han Cheng sat here, looking at the data recorded in the notebook for comparison.

After a while, he looked up.

But his brows were a little tight.

The reason for this is that by comparing some data between the smelting of iron with coal and the smelting of iron ore with charcoal, Han Cheng found that the efficiency of smelting iron with coal has not improved much.

This discovery made him very puzzled.

According to the various properties of coal, such a thing shouldn't happen.

After all, this is a good fuel that has been tangibly proven in later life.

Han Cheng sat here and kept thinking, puzzled.

Mao, Xiong You'er, and other people from the Qingque tribe, looked at the gods who sat there staring at their little books in a daze, and the whole person looked unhappy, and their hearts were full of puzzlement.

Some people couldn't help but reached out and scratched their heads.

It has been proven that coal, a stone, can be used not only for burning, but also for smelting iron.

And compared with charcoal, the same amount of coal burns longer than charcoal.

More importantly, coal is more accessible.

According to people returning from the Red Tiger tribe, there are many of these black stones.

Just dig it out, transport it to your own tribe, and burn it directly.

Unlike charcoal, many processes are needed before it can be turned into a finished product for iron smelting.

Shouldn't it be right for your tribe to be extra happy when it gets such a good thing?

Why doesn't the son of God look very happy?

Could it be that the son of God is still not satisfied with such things as coal?

After such thoughts came to mind, several people in Mao lost their senses for a while.

But thinking about some of the daily behaviors of the gods, a few people can basically be sure, which is most likely the truth of the matter.

But it is precisely because of this that several people will be so lost.

The Son of God is the Son of God, and the vision is not comparable to those of them!

Under the dumbfounded and admiring gaze of a few people, Han Cheng got up from the sitting stone, smiled and waved to the few people in the trade, asked them to come over and explain things to them.

This is of course not because Han Cheng has already figured out the joints, but because he feels that the most important thing now is to arrange for people to go to the Red Tiger tribe to find digging and transport coal here.

Although the coal at this time did not achieve the desired effect, it was still usable.

After making a comparison with charcoal, under the current circumstances, it is more cost-effective to dig from the Red Tiger tribe and transport coal to the Tieshan residential area than to cut wood and burn charcoal.

As for the problem that the efficiency of coal used to smelt iron is not as high as in my own impression, it can be considered and considered while transporting coal to my tribe.

This choice is the most cost-effective for the current tribe.

"...Go call the previous team, bring weapons, and tools such as backpacks, copper lifts, copper hammers, etc., let's go to the Red Tiger tribe to dig coal!"

Han Cheng explained to Trade and others.

Originally, Han Cheng didn't go this time.

But I remember that this is the first time that coal has been officially mined~lightnovelpub.net~ People in the tribe are not familiar with this.

Where the coal is stored in the Red Tiger Tribe and how much the coal is stored, I don’t know how much coal is stored. After waiting for these things, Han Cheng finally made the decision to take the people to the Red Tiger Tribe to conduct a personal survey .

Only by touching all of these things and knowing it well can we proceed with the next many things.

Of course, in addition to these, Han Cheng has some other plans.

This matter is related to coal, but also to the future development of the tribe and the Red Tiger tribe.

It is a very important move.

It is also more sophisticated.

Han Cheng was a little worried that the rest of the tribe could not do well, so he wanted to do it himself...
