Prehistoric I was pinched out by Nuwa

Dig the soil and drop the seeds.

buried.

Li Yang held a handful of wild vegetables in his hand.

Lingtian is full of things, and if we don’t pull out some wild vegetables, there is no place to plant seeds.

Three seeds, I don't know what kind of seeds they are.

Li Yang didn't care, and directly scattered the seeds together.

"These three seeds, come to me after they germinate, I hope they are not some weeds!"

The sign-in system is not ordinary. If it is a mysterious seed, it is a mysterious seed, which cannot be analyzed by divine analysis.

Zhu Meng responded, Li Yang turned and left.

Today Axi is going to teach those selected clansmen, and Li Yang is going to continue digging into technological knowledge.

Mathematics knowledge does not stop at the stage of university.

However, Li Yang does not intend to continue to accept mathematics knowledge.

Instead, prepare to dig deeper into other disciplines.

Next subject, Li Yang plans to start with biology, chemistry, and physics.

As for the liberal arts, there is absolutely no need.

Can't get out the historical knowledge?

The history of the previous life and the history in the prehistoric world are not on the same line at all.

Or engage in politics in the wild?

Still, the role of science is relatively large.

Science and technology knowledge must be science.

Three disciplines, which one to start with?

Li Yang thought for a while, and finally decided to start with chemistry knowledge.

Chemistry knowledge may be changed through the check-in system, and there may be psionic subjects.

For example, the numerical model is the product of the combination of mathematics and spiritual energy.

Start with chemistry knowledge.

Mathematics and Chinese can both make related behaviors, so what about chemistry?

Li Yang thought to himself that he doesn't know chemistry.

Oh, yes, gunpowder.

Gunpowder is the product of chemical knowledge. If you think about gunpowder yourself, the sign-in system should not reward knowledge of gun manufacturing, right?

If the overall chemical knowledge can be obtained, no matter whether it is a common element or a rare element, it should be able to obtain it in the future.

Of course, relevant technology needs to keep up.

With a decision in mind, Li Yang started to make gunpowder.

After a whole day, Li Yang made himself dirty.

Naturally, Li Yang couldn't make the materials for making gunpowder that the human race didn't have.

But what he wants is not to create gunpowder, but to 'cheat' the sign-in system.

What I am doing is chemistry-related actions!

Should knowledge of chemistry be rewarded?

In the past, knowledge was rewarded immediately, which is basically practical.

However, it is not universal.

Dinner, finished.

Li Yang didn't have anything to say, so he went back to his room.

Then sign in.

"Congratulations player..."

The knowledge of junior high school chemistry that I have been thinking about is in hand.

Change breathing, sleep.

The next day.

Li Yang carried a carving knife and engraved the knowledge of chemistry.

He studied the knowledge of chemistry, but he had never learned it in his previous life, so he didn't know how the knowledge of chemistry was in his previous life.

However, junior high school chemistry knowledge does not include spiritual energy.

Most importantly, in this chemical knowledge, there is the periodic table of elements.

This seems to be the basis for learning chemistry?

In addition, Li Yang also saw that water produces oxygen...

When he saw oxygen, Li Yang thought that there can't be oxygen in the nine heavens, right?

So, for the existence that can be thrown beyond nine days, the body does not need oxygen?

Or there is spirit energy above the nine heavens?

Li Yang couldn't figure it out, so he simply didn't think about it.

When the relevant levels are involved, these doubts will be easily resolved.

After the junior high school chemistry was engraved, Li Yang put it in his personal space.

In chemical knowledge, there are related processes such as manufacturing steel, glass, and steam.

If this knowledge is learned, it will greatly change the human race.

It turns out that the relevant knowledge of ironmaking is also included in the chemical knowledge, and they are just a small branch.

Secretly stunned, Li Yang wondered why he didn't think about chemistry knowledge at that time?

The sign-in system can provide physical rewards, knowledge rewards, and occupations.

One word, strong.

Although it is not smart, but at any rate there is no task to do.

Just sign in every day.

After Li Yang finished engraving the chemical knowledge, he thought for a while and chose to continue signing in.

In the evening, what will happen in the morning?

"Congratulations to player Li Yang for successfully signing in..."

Crash.

Knowledge rushed to Li Yang's brain like flowing water.

His impoverished brain froze instantly.

Bang!

Li Yang fell to the ground on his back.

"Big brother..."

Ah Xi who was cooking, Zhu Meng, A Tao and others who were waiting to eat, panicked when they saw their eldest brother collapsed straight up.

……

It seemed like a long time, and it seemed like a moment.

Li Yang felt a little pain in his head.

He opened his eyes.

Haven't spoken yet.

"Brother is awake!"

"Brother, what happened to you just now?"

After a burst of noisy voices, Axi finally spoke.

"Just now I……"

Li Yang recalled what happened just now, and directly changed the evening sign-in to morning.

Then countless chemical knowledge rushed into his mind, and he passed out instantly as a result.

"I'm fine!"

Li Yang rubbed his head, and now he feels his head is still buzzing.

It should be the reason why knowledge comes too fast.

A Xi's eyes showed a worried look, and he would suddenly pass out if nothing happened.

It really scared her just now.

"It was a small accident just now, I'm fine!"

Li Yang checked his own body, and it was indeed all right.

But Li Yang was a little puzzled.

His brain can absorb university knowledge, why can't high school chemistry knowledge bear it?

The knowledge of signing in in the morning is not other knowledge.

High school chemistry knowledge.

"What time is it?"

After Li Yang asked, he knew what time it was.

Afternoon, about two o'clock.

The sundial in his body vibrated when Li Yang asked.

"Two o'clock!"

Ah Xi also gave an answer.

Li Yang sat up from the bed.

He glanced at it, it was his own room.

Ah Xi and others should have carried him in.

In the room, it can be said that everyone gathered together this time.

Even the second child who was practicing at the vines and cypresses came over.

"I was in a coma just now, there is a reason!"

Seeing everyone's worried eyes, Li Yang decided to explain.

Otherwise, they may keep posting this matter.

Li Yang opened his mouth, but no one spoke.

But their eyes were on Li Yang, waiting for the eldest brother to continue talking.

"Axi, when I taught you mathematics these few days, did you feel a little dizzy at the end of the day!"

Axi nodded.

The rest were a little stunned.

The eldest brother has been teaching Axi to learn mathematics these days?

It can be said that Zhu Meng, the second child and the others knew nothing about it.

Because Atao heard this from Axi's mouth, there was no surprise on his face.

"Second brother, Xia An... I don't teach you, you are the ones who are concentrating on cultivating, so it's better not to be interrupted by this knowledge!"

The second child nodded hurriedly.

"Brother is right!"

Xia An thought for a while, then nodded slowly.

Li Yang glanced at the second child, he thought it was because the second child did not want to study mathematics.

This thing is more difficult.

He obviously had such a curious heart, but when he came across mathematics, it went out.

What's the point.

Li Yang thought of his second child's study progress, he thought it would be best for his second child to not be curious.

Practice honestly!

"Brother, is your coma related to your knowledge of mathematics?"

Axi caught the point.

"It has nothing to do with mathematics, but it has something to do with another subject!"

Li Yang said softly: "The knowledge I teach, in addition to mathematics knowledge, there is another subject, that is chemistry!"

"Like what's in the water?"

"For example, how does rainwater... There are several ways to form!"

Li Yang thought that the wind and rain could be summoned in the prehistoric world, so he directly changed the formation of rainwater into several formation methods.

For example, some people directly suck up the water from a river with a magic weapon, and then it falls from the sky... This is also rainwater, isn't it?

"And the formation of clouds and things like that..."

After Li Yang finished speaking, he saw that Axi and the others were a little confused.

He turned to look at the second child.

"My second child's curiosity in the past can basically be answered by chemical knowledge!"

"This subject is called chemistry!"

"This subject is relatively advanced. If you don't start from elementary school, you will start at the terrible middle school level!"

"The reason why I fell into a coma was because I received high school chemistry knowledge. Because I received it too quickly, my brain couldn't bear it for a while, so I passed out in a coma!"

"This is the brain's sense of self-protection!"

Li Yang didn't ramble, after explaining it again.

Finally said: "Brain self-protection awareness, this is also a subject, after I sort it out, you all have to study it!"

Except for the bitter face of the second child who found it difficult to learn, everyone else nodded to show that they listened to the elder brother.

Li Yang thought, after the knowledge of the tribe reaches a certain level, maybe the human race can reproduce!

The knowledge of life contains the knowledge of reproduction.

Thinking of reproduction, Li Yang inexplicably thought of past life medicine.

However, is there still room for medicine in this world?

A elixir may bring people back to life, even if the body is smashed, there is still a soul.

As long as the soul is there, it is possible to reshape the body out of the rest.

When Li Yang thought of this, the medical class might become psychic medicine.

Wound repair and severed finger regeneration without leaving scars at all.

However, if possible, I still have to get some medical knowledge.

Maybe the medical knowledge combined with Lingqi has a great effect?

"What I'm saying now is just to prepare your hearts! Later, I will teach Axi all the relevant knowledge, and then let her teach you!"

"Or, you put down your current practice and learn with Axi?"

"I'd better practice first!"

After the second child made sure that the elder brother was fine, he left in a hurry.

It seems that if he is satisfied, Li Yang will grab him and let him learn.

"Brother, Lingtian still needs to be taken care of..."

Zhu Meng also left!

Xia An and the others also left.

After a while, Axi and Atao were left in the room.

"Brother, I want to learn with Sister Axi!"

Apart from logistical matters, Atao has nothing else to do.

The other thing is to practice in closed doors, which she thinks is too boring.

In addition to eating, it is cultivation.

Learning knowledge can also help the tribe, and she thinks learning knowledge can also do it.

"Well, yes!"

Although Atao is not as quick-learning as Axi, he can learn along with him.

If you can't learn it, ask Axi again.

"You follow the tribe selected by Axi to learn the mathematics and Chinese in elementary school!"

"After you have learned this knowledge, you can proceed to the next step of learning!"

After saying this, Li Yang rubbed his stomach.

He hasn't had breakfast or lunch, and he's a little hungry now.

"Brother, I left the food for you!"

Ah Xi saw her elder brother's movements, turned around and went out.

"Let's go out too!"

Li Yang called Atao and left the room.

The head is still a little swollen, but it is much better than before.

After eating, Li Yang felt much more comfortable.

"Brother, are you feeling better now?"

"how?"

"Our people are slower to learn knowledge. I talked too much yesterday. Let them review it by themselves today!"

Li Yang suddenly realized that what Axi said was to learn new knowledge.

"I'm fine now! I'll teach you about the sixth grade later!"

After saying this, Li Yang turned to look at A Tao.

"How is the negotiation with the Qingyi clan?"

"They are willing to pay a piece of bamboo joint liquid!"

"Bamboo?"

A Tao took out the bamboo knots, Li Yang was speechless after seeing it.

I thought the bamboo joints were those with thick arms.

The result is a thumb-thick bamboo knot.

But slightly longer, about ten centimeters.

Use bamboo energy saving to hold spiritual liquid?

Li Yang was puzzled by this.

Won't the spiritual liquid penetrate the bamboo joints?

Li Yang found bamboo knots and found that they were not very sealed.

The thick bamboo joints of the thumb are still plugged with wood.

Really spartan.

Not as good as refined pottery.

Among the refined pottery, there are also bottles and the like.

It is not appropriate to call it a bottle, it should be called a clay pot.

Utensils such as small devices have not been refined.

When the cork was opened, the spiritual liquid did not dissipate.

Li Yang took a look, and it was like clear water.

If he hadn't felt the strong spiritual energy in it, he would have probably regarded it as clear water.

No attributes.

This bottle of spiritual liquid has no attributes.

"Brother, are these okay?"

Atao was a little apprehensive.

"Of course!"

Li Yang plugged the cork, and then handed the liquid to A Tao.

"These spiritual fluids are equivalent to half a month of cultivation! Since you want to learn, your cultivation will inevitably be very slow!"

"Drink some while practicing!"

Even the spirit qi can be breathed in directly through the nose, not to mention the spirit liquid.

"Sip!"

"If you drink too much, your body can't absorb it, so it's a waste!"

Compared with other parts of the body of the human race, no matter whether it is good or bad, it will absorb it together.

"Ok!"

Atao put it away carefully.

"For those who arrange the Qingyi tribe to learn, you can choose the tribe to teach!"

Li Yang still leaves these matters to A Tao.

After Axi rinsed the tableware used by Li Yang with clean water, she followed Li Yang back to the room.

"Let's learn mathematics first! Try to finish the sixth grade mathematics today!"

"Ok!"

There is still a lot of mathematics knowledge left in the sixth grade.

With only half a day's time, Li Yang thought he couldn't finish teaching.

As a result, when I started teaching today, I found that Ah Xi learned very quickly.

"Did you preview in advance?"

"Preview?"

"It's just reading the knowledge of the sixth grade in advance!"

Axi nodded.

"When I teach the people of the tribe, when they study, I will also look at the back! Brother, is it okay for me to do this?"

"Of course, it's a good thing to understand the problem!"
