I am a primitive

The broken pieces of coal were scattered all over the place.

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

Han Cheng's sudden action immediately blinded people.

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

Yang Yao and the others who were smiling and excited just now, the smiles on their faces disappeared quickly, and they stood there looking at a loss.

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

The reason is that the black stone brought back by himself and others is not the coal that the Son of God said.

If not, how could the Son of God smash it to pieces?

Han Cheng didn't care about these.

At this time, he was squatting on the ground, carefully watching the crushed coal.

The fractured coal stone showed a familiar appearance to Han Cheng.

In the darkness, there is some light.

This is the most important reason why Han Cheng suddenly threw the coal stone away.

Because he suddenly thought that the surface of the coal stone can be weathered, but the inside will not be weathered away!

At this time, I opened it and saw that it was so.

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

Han Cheng turned his head and saw the strange expressions on everyone's face. He smiled and said to everyone.

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

"Let's do the last test later, so as to thoroughly confirm whether this thing is the coal we want!"

Han Cheng said so.

Although it was basically confirmed that this thing was coal, Han Cheng still wanted to test it again just to be on the safe side, so as to thoroughly confirm whether this thing was coal.

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

……

Many people gathered beside 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.

"Crash..."

With such a sound, the flame in the stove suddenly became much smaller.

Han Cheng, holding a copper shovel, stood here, looking at the black crushed stones placed in the furnace, with anticipation on his face.

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

"Increase the firepower!"

Han Cheng said, with some excitement in his voice.

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

Puffs of air rushed into the stove.

Everyone couldn't help holding their breath, stood on tiptoes, stretched their necks and looked into the stove.

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

Stones, in their impression, have never been able to burn.

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

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

Not only can it burn, but it can also burn extremely powerfully!

Coal is more useful than charcoal fired from wood!

Although they knew that it was impossible for the Son of God to deceive them, they still wanted to take a look at such a strange thing that was obviously contrary to common sense.

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

As the person pushing and pulling the bellows continued to push and pull the bellows, puffs of thick smoke rose from the stove.

There was some familiar choking smell in the air.

Smelling the smell, Han Cheng couldn't help but smile all over his face.

That's right.

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

What Yang Yao and others found was coal!

While Han Cheng was waiting with a smile on his face, and as the Qingque tribesmen surrounded him waited with anticipation, the thick smoke from the stove became less and less, and the coal dumped by Han Cheng was overwhelming. The ignited flame began to drill out from the cracks in the coal.

And it's getting bigger.

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

Firewood burns with a milder flame.

The flames that emerged at this time did not seem to be as big and high as the flames burned by firewood.

However, just by looking at it, one can feel the temperature contained in it, which is far higher than that of ordinary flames.

Of course, this feeling can only be felt by people like Han Cheng who have seen the coal burning in the iron furnace and the cutting guns used to cut steel plates at high temperatures in later generations.

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

On the black coal, many parts have turned red, which looks like burning coal!

At this time, the dry wood placed at the bottom of the stove and used as a fire starter has been completely burned.

There are only coals left in the stove!

Such a scenario can fully prove one thing.
