Prehistoric I was pinched out by Nuwa

The charcoal cellar is fired once, and it will be destroyed once fired.

If firing for the second time, a new cellar must be built.

Li Yang's method of firing charcoal pits is just like this.

He didn't dare to be sloppy in firing this time!

For the charcoal cellar, the head is sealed, and eight air inlets are left at the lower end!

Burning charcoal seems to use high temperature to dry out the moisture and other trace elements in the charcoal?

Li Yang doesn't know the principle, he only knows how to fire it!

Which should involve chemical knowledge.

Chemistry belongs to science, which is beyond the scope of his knowledge as a liberal arts student.

He can only proceed step by step according to the firing method obtained.

After sealing the upper head, the next thing Li Yang has to do is to observe the remaining eight air inlets.

Whichever air inlet can observe the flame, you need to bet on this air inlet immediately!

As for the principle, Li Yang thought that readers of science majors should know.

"Big brother!"

It was the second child who shouted.

The second child, Xia An and the others finished this course, and they came to look for Li Yang.

From the people of the clan, they learned that the elder brother was making some incomprehensible things again.

When they came over, they saw the elder brother peering into a small hole.

The second child is the one with the most thirst for knowledge among the few.

"What is this?"

"Make charcoal cellar!"

The second child, Xia An and the others were at a loss.

Li Yang didn't need to look at their expressions to know that they didn't understand.

If he has not learned how to make charcoal, he does not know how to make charcoal.

This was not a common sense thing in the previous life.

Maybe you have heard it before, but you really want to do it.

But I found that my brain thought it would, but it was useless when I started it manually!

"I'll teach you guys after I figure it out in a few days!"

Whether making pottery cellars or making charcoal cellars, he will teach the tribe one by one!

Charcoal kiln firing is not done overnight, after all, it should take a lot of time to dry the moisture in the wood.

While Li Yang was talking to several people, he didn't let go of his observation of the charcoal cellar.

When there was an air inlet where the flames could be seen, Li Yang directly blocked the air inlet with mud!

Continue to observe the others.

First

第二 个

The third

……

All eight air inlets were blocked!

This means that the charcoal cellar is completely made, and then only the bamboo in the charcoal cellar can be fired for a few days.

Tell the clansmen to take good care of the charcoal pit, and never damage the charcoal pit.

When the charcoal was fired successfully, he could start firing porcelain.

Porcelain is harder and more durable than pottery.

It is incomparable with iron and steel.

And with charcoal, he could even try to make iron.

Firing iron should be easy!

Li Yang, remember to fire the iron at high temperature!

The ancients could make it, but he, who has experienced all kinds of knowledge in his previous life, can't do it?

Iron smelting at high temperature!

common sense!

How are bronzes fired?

He remembered that some books in his previous life recorded that bronze wares were the first to appear!

Are bronzes also fired?

As for Tong, Li Yang remembers that there are many places in this prehistoric place.

It seems to be in Shouyang Mountain.

But where is Shouyang Mountain?

Li Yang's eyes were darkened, he only knew the names of places, how could he know the exact location?

Unless you get his cell phone from his previous life, download a map and enter the destination directly.

It was because of the sun that he could tell the difference between southeast and northwest in the prehistoric times.

Seeing that the eldest brother didn't explain what charcoal was, they suppressed their curiosity and didn't ask any more questions.

"Where are Axi and Zhu Meng?"

Only Lao Er, Xia An, and Atao came, but Ah Xi and Zhu Meng were not there.

"Brother, Axi is dealing with the monkey brain, she left Zhu Meng to help him!"

Li Yang didn't tell Axi what the monkey brain looked like, he didn't know if Axi could handle it.

Without talking nonsense with the second child, he went to look for Axi.

Ah Xi and Zhu Meng are by the stream.

The two of them surrounded a skinned monkey, and they were a little helpless.

They don't know what a monkey brain is

"Axi, Zhu Meng!"

Li Yang felt that what he saw was exactly what the two of them didn't know how to do.

He patted his head, it was his own negligence.

To be born is not to know oneself.

The mouth, ears, nose, tongue, and eyes are all learned after a little bit of learning.

He caught mountain deer, long-eared rabbits, or black wind tigers before, but he just demonstrated how to deal with them in front of a few people, and he didn't tell them the names of the limbs of these beasts.

"Big brother!"

Ah Xi and Zhu Meng were very pleasantly surprised.

The two were very worried about Monkey Brain.

This gibbon monkey, which part of its head is!

"Axi, Zhu Meng, do you two know the head of the gibbon monkey?"

"I don't know!"

"I don't know why you didn't ask me?"

Li Yang frowned, he didn't tell Ah Xi that the limbs of the beast were his negligence.

But why didn't the two of them ask, even though they didn't know?

The reason why Li Yang forbids his clansmen to eat indiscriminately is also out of this consideration.

I don't know where it came from, and it's a trivial matter to eat a bad stomach, but I'm afraid of eating my own life.

"We see you are so busy, we think we can handle it!"

"You guys!"

Li Yang couldn't say what he reprimanded, and the two of them probably didn't want to bite the bullet and deal with the monkey brain.

I guess I want to help myself bear some things, so I don't want to call him.

He taught the tribe to weave nets to catch fish and birds, build houses, weave bamboo baskets, and burn pottery.

Now it continues to teach the tribe to recognize numbers and characters.

The more the tribe learns, the more things they do.

Every time there is a new thing, a part of the tribe must be mobilized to learn it first and then manufacture it.

Now in the territory of the human race, there are teams dedicated to felling trees; teams dedicated to moving stones; and teams dedicated to weaving.

Many teams seem to perform their duties, but there are also a lot of problems.

How much does it take to cut down trees?

What is the geometry of the stone?

How much is the woven bamboo basket fishing net?

The people in the clan don't know about these problems, so how can Li Yang not know?

He has nothing to do at the moment, the people of the clan don't know how to read and write, how to solve the problems that gradually arise?

Li Yang wants to do many things, looking for salt, iron ore, copper ore, fruits and vegetables, etc.!

But he is only one after all!

They are at the foot of the unknown mountain, and this is not a past life where there are no ferocious beasts.

If you are careless, some people may die!

Li Yang did not criticize Axi and Zhu Meng.

But he still explained to the two of them, if there are some things that you don't understand, try to ask him first!

Ah Xi and Zhu Meng would naturally not go against what their elder brother said.

After explaining to the two of them, Li Yang turned around and explained the same to the second child, Xia An and Atao.

The three of them hurriedly nodded in agreement.

They didn't know how big the world was before, and naturally they didn't know the dangers around the territory.

Although they don't know how big the world is now, the incident with the Black Wind Tiger last time left a deep impression on them!

They think that the surrounding environment of the territory is strange, and wild animals will appear at any time.

"How to deal with the monkey brain, let me tell you!"

Li Yang took Shidao: "Second brother, you guys also have to listen carefully, this time is also learning!"

He was going to borrow the gibbon monkey corpse for a teaching session.
