To make honeycomb coal, you need to smash large coal blocks, then mix some yellow mud, mix them with water, and then beat them into honeycomb coal with a ball beater.

At that time, although I was still young, I was basically not involved in the process of making honeycomb coal, but I still experienced close contact, touching the coal and making my face black, and my clothes black, and then being beaten.

Because of his close experience, Han Cheng still knows a lot about coal.

It is also because of this that when he first saw it, Han Cheng was basically able to determine that the thing he was holding in his hand was coal!

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

Something to start with heavy.

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

It's not like the lumps of coal that come out of the mines, which shimmer in the sunlight.

However, judging from the luster of the hand and the successful dyeing of the hand black, it can basically be recognized.

Han Cheng stood here and watched for a while, then walked a few steps to the side, came to the edge of a stone, and smashed the large piece of coal stone he was holding in his hand against this stone!

"Bang~"

With a muffled sound, the coal stone immediately fell apart.

The shattered pieces of coal were scattered all over the ground.

One of the coals collapsed directly at the feet of the sheep's waist.

Han Cheng's sudden move directly blinded people.

People don't know why the god son of their tribe suddenly changed his face and became so angry.

The smiles on the faces of the sheep waist and the others, who were still smiling and excited just now, quickly disappeared from their faces, and they stood there looking at a loss.

After a brief moment of confusion, they thought of why.

The reason for this is that the black stone that he and others brought back is not the coal that the Son of God said.

If it weren't for that, how could the Son of God have smashed it to pieces?

Han Cheng didn't care about any of this.

At this time, he was squatting on the ground, carefully looking at the broken coal.

The fracture of the broken coal stone showed a familiar appearance to Han Cheng.

In the darkness, there is some shine.

This is the most important reason why Han Cheng suddenly broke this coal stone.

It occurred to him that the surface of the coal and stone could be weathered, but the inside would not be weathered!

At this time, I opened it and saw that it was indeed the case.

"This is a means of checking! Now I'm pretty sure that this black stone is coal! ”

Han Cheng turned his head and saw everyone's strange looks, and immediately said to everyone with a smile.

After hearing his words, the people in the tribe immediately became relieved and happy.

"We'll do one last test to make sure if this thing is the coal we want!"

Han Cheng said.

Although it was basically certain that this thing was coal, Han Cheng wanted to test it again to thoroughly confirm whether this thing was coal or not.

The method of this test is very simple and straightforward, that is, - burn!

……

There are a lot of people gathered next to an iron-striking stove in the Iron Mountain residential area, and firewood and grass are lit in the stove.

Under the impetus of the bellows, the firewood and grass in it are particularly vigorous.

"Boom la la ......"

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

Han Cheng, holding the copper shovel, stood here, looking at the black broken stone that had been placed in the furnace, with anticipation on his face.

The copper shovel he held in his hand was stained with some black ash.

"Fuel up!"

Han Cheng said, with some excitement in his voice.

After his voice fell, the person who was squatting under the stove and pulling the bellows immediately accelerated the frequency of the push.

Streams of air rushed into the stove.

Everyone couldn't help but hold their breath, stood on tiptoe, and craned their necks to look into the stove.

As for what the Son of God is doing, everyone's hearts are full of curiosity.

Stones, in their minds, never burned.

Even if it is iron ore and copper ore, which can be melted by flames, it will not be burned.

But now the Son of God is telling them that coal, a black stone, can be burned.

Not only can it burn, but it can burn very badly!

Coal is much easier to use than charcoal made from wood!

Although they knew that it was impossible for the Son of God to deceive them, they still wanted to see the strangeness in the face of such a strange thing that was obviously contrary to common sense.

See if this stone can really burn as the Son of God said.

As the people pushing and pulling the bellows kept pushing and pulling the bellows, puffs of smoke rose from the stove.

There was some familiar choking smell in the air.

Smelling this smell, Han Cheng couldn't help but smile.

That's right.

This exudes a strong pollution, but at the same time represents a civilized and advanced taste, that's it!

What the sheep waist and others found was coal!

In the waiting with a smile on Han Cheng's face, in the anticlieving waiting, the smoke coming out of the stove became less and less, and the coal that was dumped by Han Cheng, the flames that could not be suppressed, began to drill out of the cracks in the coal.

And it's getting bigger.

This flame is not quite the same as the flame of ordinary firewood.

The flame that comes out of a firewood fire is relatively mild.

The flame that comes out at this time does not seem to be as big as the flame that burns with firewood, and the flame is high.

However, one only needs to look at it to make people feel that it contains a temperature that is far higher than that of ordinary flames.

Of course, this feeling is basically only felt by people like Han Cheng who have seen the burning of coal in an iron furnace and the cutting spear that uses high temperature to cut steel plates in later generations.

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

Many parts of the black coals have turned red, and they look like hot coals!

At this time, the dry firewood that was placed at the bottom of the stove and used as a fire-starting object was completely burned.

All that's left in the furnace is lumps of coal!

Such a scenario can fully prove a thing.

This thing is that what is burning at this time is black stone, coal!

In such a scene, the people of the Qingque tribe around them widened their eyes, and they felt surprised and infinitely happy!

This thing is really the same as what the Son of God said, it can really burn!

Because of the successful burning of coal, a black stone in the eyes of everyone in the Qingque tribe, the entire Qingque tribe's Tieshan residential area has become extremely lively.

The crowd was filled with a sense of joy and cheerfulness.

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

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

After learning about this, Han Cheng was stunned.

The news came as a surprise to him.

As early as before, he had thought about how good it would be if there was also a coal mine in the Red Tiger Tribe.

But such thoughts are 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, and he really doesn't dare to think too much!

However, he didn't expect that reality gave him more than he imagined.

It was totally beyond his expectations!

This Red Tiger Tribe is really a treasure of feng shui!

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

It would be a pity not to include such a treasure of feng shui in your own tribe!

"Boom la la ......"

At an iron-smelting furnace in the Tieshan residential area of the Qingque tribe, there was such a sound again.

The iron smelter, holding a copper shovel, scoops up the smashed coal and adds it to the furnace.

Then he began to pull the bellows hard.

When it gradually burned and confirmed that it would not be extinguished, he began to add smashed iron ore to it.

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

Han Cheng had long thought of replacing charcoal with coal and making it the main smelting metal fuel.

Now the tribe finally got coal.

In such a situation, Han Cheng wanted to try as quickly as possible anyway.

Therefore, after it was thoroughly confirmed that this thing was indeed coal, the use of coal instead of charcoal for smelting in the tribe also began.

The bellows are pulled, the furnace fire burns, and the temperature in the furnace continues to rise.

Later, an orange-red flame climbs along the stove and eventually reaches the upper part of the stove, revealing that the furnace radiates with an extremely high temperature.

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

"......"

There was a slight thud, and a stream of fiery molten iron flowed out of the furnace and landed in the earth groove below......

Han Cheng sat here, looking at the data recorded in the small book and making comparisons.

It took a while before he looked up.

However, the brow is a little tight.

The reason why this is the case is because through the comparison of some data between iron smelting with coal and iron ore smelting with charcoal, Han Cheng found that the efficiency of iron smelting with coal did not improve much.

Such a discovery made him very puzzled.

According to the performance of coal, such a thing should not happen.

After all, it is a good fuel that has been proven in later generations.

Han Cheng sat here and kept thinking, puzzled.

Mao, Xiong Youer and some other people from the Qingque tribe looked at the god son who was sitting there staring at Xiao Benben in a daze, and the whole person didn't look happy at all, and their hearts were full of puzzlement.

Some people couldn't help but reach out and scratch their heads.

Coal is a stone that has been proven to be used not only for burning, but also for smelting iron.

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

More importantly, coal is easier to obtain.

According to people who have returned from the Red Tiger Tribe, there are many of these black stones there.

All you need to do is dig it up and transport it to your tribe to burn it directly.

Unlike charcoal, it still needs to go through a lot of processes before it can finally be turned into a finished product and smelted iron.

Shouldn't my tribe be extra happy to get such a good thing?

Why doesn't Miko seem so happy?

Could it be that the Son of God is still not satisfied with such a thing as coal?

After such a thought came to mind, the trade people were a little distracted for a while.

However, thinking about some of the behaviors of the Divine Son on weekdays, several people can basically be sure, and this is very likely to be the truth of the matter.

But it is precisely because of this that several people will lose their minds like this.

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

Under the stunned and admiring gazes of several people, Han Cheng got up from the stone he was sitting on, and began to smile and wave to the others, asking them to come over and explain things to them.

Of course, this was not because Han Cheng had already figured out the joints, but because he felt that the most important thing now was to arrange for someone to go to the Red Tiger Tribe to find digging and transport coal here.

At this time, although the coal did not achieve the desired effect, it was still usable.

After a comparison with charcoal, it is still much more cost-effective to dig and transport coal from the Red Tiger tribe to the Tieshan settlement 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 I remember, I can think about it while transporting coal to my own tribe.

Such a choice is the most cost-effective for the current tribe.

“…… Go and call a team of people, bring weapons, and tools such as back baskets, copper lifts, copper hammers, etc., and we will go to the Red Tiger Tribe to dig coal together! ”

Han Cheng explained to the trade and others.

Originally, Han Cheng didn't go this time.

However, remembering that this was the first time that such a thing as coal had been officially mined, the people of the tribe were not familiar with it.

Where exactly the coal was stored in the Red Tiger Tribe, and how much it was stored, he didn't know after waiting for these things, so Han Cheng finally made the decision to take everyone to the Red Tiger Tribe in person to investigate it in person.

Only by touching all these things and knowing them in your heart can you move on to the next many things.

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

This matter is related to coal, but also to the future development of his own tribe, as well as the Red Tiger tribe.

It is an important move.

At the same time, it is also more delicate.

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