Prehistoric I was pinched out by Nuwa

The territory of the human race, in front of the Taiqing residence.

Ah Xi held a clay pot in his hand, with steam on it.

She looked at the closed door in front of her, feeling a little apprehensive.

Senior Taiqing is such an expert, would he like this eagle demon broth?

The door of the house is closed tightly, and the seniors should practice in the house.

Wouldn't it disturb the senior if he knocked on the door?

Can you not knock?

Ah Xi looked down at the clay pot in his hand, if he didn't knock on the door, the eagle demon broth would not taste good when it was cold.

"Put it outside the door!"

A faint sound came from the wooden house, which made Axi very happy.

"Yes!"

Ah Xi respectfully put down the clay pot in his hand, and then retreated.

When Axi receded, the door of the wooden house opened a gap.

Whoosh, the clay pot entered the wooden house, and the door closed immediately.

Inside the house, Taiqing looked curiously at the clay pot of eagle demon broth in front of him.

The overall appearance is milky white, and the lines are like patterns and floating catkins, which is quite beautiful!

There is a long-handled spoon in the clay pot.

Taiqing has seen how the human race uses this spoon, he used a small spoon last time.

Picking up the spoon, Taiqing subconsciously stirred the clay pot.

A seductive fragrance rushed towards his face, making him unable to hold back his index finger.

After taking a spoonful, Taiqing's face revealed an intoxicated look.

The way humans eat is so delicious?

He and his two brothers practiced in the mountains, and it is not that they do not eat meat.

Especially the third brother, Shi Chang brought some birds and beasts to beat the teeth, but the smell made people feel insensitive.

After several times, he gave up these things and concentrated on cultivation.

That little gray-feathered eagle, after being steamed in that pottery pot, will emit such a smell!

Incredible!

Taiqing felt emotional in his heart, thinking of the corpse of the thousand-meter-long gray-feathered eagle demon from before.

Those eagle monsters offend the human race, they should all be left behind!

Outside the house, where Li Yang and others eat!

Several people have already learned that Taiqing left behind the pot of eagle demon broth.

Li Yang was rather surprised, Taiqing is about to become a saint?

Such food, is it worth it?

He doesn't understand.

Just because he doesn't understand doesn't mean he won't come.

"When cooking soup from now on, give Senior Taiqing a copy as usual!"

After ordering, let a few people do things.

Li Yang leaves Axi behind.

"You come with me!"

Among them, only Axi is the smartest.

Once something new appears, Li Yang will definitely bring Axi with him.

Axi learns knowledge faster, and she learns new knowledge, which means that there is a second person in the human race to learn besides him!

When teaching, he is not alone!

Li Yang was very clear about how to arrange for these people.

Charcoal cellar.

Li Yang waved his hand to let the guards push him away.

He has a stone pick in his hand!

Axi looked at the charcoal cellar with curious eyes. A few days ago, she saw her elder brother working on it, and there was a fire behind it.

"This food I made, it's called charcoal! I don't know if it's successful!"

Li Yang took the stone pick and tapped on the charcoal cellar.

Soon, the circle around the charcoal cellar cracked slightly.

Li Yang didn't use Axi's help, he scraped off the cracked dry soil piece by piece with his hands.

When he opened the upper layer of the charcoal cellar, a wave of warmth rushed to his face.

Four days, still warm!

Li Yang was quite worried, could it be that the burning has not finished yet?

He removed the last layer of dry soil around the charcoal cellar, exposing the dark things inside.

Axi tilted her head aside, isn't this left after the firewood was burned?

Seeing this scene, Li Yang felt a little cold in his heart, he couldn't really fail!

When he fired, he strictly followed the steps without any mistakes.

Li Yang looked at the black powder, he gently pulled it out with a stone pick!

The powder fell off, revealing a dark, cracked item.

Li Yang saw this bright existence, and his eyes showed joy.

He hastily pulled it twice with his hands.

It's charcoal!

The charcoal is fired, which means that if the human race wants to make iron, they only need to find iron ore!

If iron is smelted, the development of the human race must be a leap forward.

"Brother, what is this?"

"charcoal!"

"It's called charcoal!"

Li Yang cleaned up the surrounding wood ashes, and he asked Axi to help the rest of the tribe to move out the charcoal together.

"Move them to the pottery cellar!"

Using charcoal to burn, some fine porcelain can be fired.

For the current human race, pottery is enough, and it is not necessary to make exquisite pottery.

Slices of charcoal are placed neatly under a newly built wooden shed.

The bottom of the wooden shed is hollowed out and covered with wooden boards to prevent the bamboo charcoal from getting wet.

The wooden shed is very large, about [-] square meters when converted into the area of ​​the previous life.

There are three wooden sheds once built!

Li Yang is making preparations for charcoal storage in the future.

"Brother, how do you use this charcoal?"

After finishing all this work, Axi couldn't help asking.

She knew that her elder brother left her alone before, so he might teach her new knowledge.

These charcoals should be the knowledge that the elder brother is about to teach.

"To be precise, it's called bamboo charcoal, and it's made from bamboo!"

The bamboo charcoal was fired, Li Yang checked it a little, the charcoal production rate was only about [-]%!

There are four layers of loss!

A lot of bamboo charcoal, it seems that there is not enough time.

Li Yang concluded that it should be because he was too anxious to open the cellar.

If it takes another two days, the charcoal production rate should increase to [-]% to [-]%?

He couldn't be sure about the accuracy rate.

Postpone the time, the carbon production rate will definitely be higher than now!

Li Yang is sure of this!

"Charcoal is very simple! It burns longer than firewood and keeps the temperature in the cellar higher!"

When firing the statue of Wa God, there is high temperature.

It is a finished product.

Li Yang directly took the statue of Wa as an example.

"The temperature is high, and every pottery made in the future may be like the statue of the mother goddess!"

The temperature required for firing porcelain is higher than that of pottery!

Earthenware is slightly more delicate than porcelain.

But pottery does not completely replace pottery.

Currently, Li Yang is not planning to fire pottery either.

Pottery is not important for the needs of the human race.

Iron ore is what Li Yang currently needs. If iron products are fired, at least he can complete the replacement of the tools in his hand!

"It turns out that the successful firing of the goddess statue was caused by the high temperature?"

"But there was no charcoal back then!"

Li Yang patted Axi on the head: "You have to understand one thing, charcoal is not the only way to increase the temperature, if there is enough wind, the temperature in the cellar can also be increased!"

"It was true that there was no charcoal back then, but there was a gust of wind!"

This wind fell from the sky, Li Yang had this guess in his mind, but he couldn't verify it.

Atao's supernatural powers can also control the wind. If she can, she can also maintain long-term blowing to increase the temperature in the cellar!

It's just that Li Yang didn't want Atao to do this!

One is that it consumes too much energy, and the other is that firing porcelain has no other effect at present.

Porcelain is more suitable as a container.

But it is far inferior to clay pots for steaming and cooking.

"While it's still early, I'll teach you how to make charcoal!"

Leaving Axi by his side, Li Yang wanted to teach her how to make a charcoal cellar.

Compared with the bamboo charcoal pit last time, this time he asked his tribe to cut down some hardwood trees.

The more 'dense' the tree, the better the charcoal should be.

The density of bamboo is relatively small, and the charcoal fired should not be as durable as hardwood trees.

Li Yang needs charcoal, but also persistence.
