In the past, Wang Yang also painted some things, whether they were high-rise buildings or busy traffic, they were all boring paintings.

But no matter what the painting is, once everyone gets up and takes a look at it, they will leave peacefully.

Because they can't understand it.

But now instead of leaving, they are mumbling something. What does this mean? Do they understand?

If he really understood it, Wang Yang would naturally be overjoyed.

You want to know why he wanted to develop their abstract thinking? To relieve the loneliness of empty nights? To paint masterpieces and only be able to admire the loneliness in isolation?

Or do you draw some funny pictures to tease the female ape?

None! It’s for communication.

If everyone is strong, the power is strong. No matter how strong one person is, what is the use if it cannot make others stronger?

It's the same as ten chopsticks that keep twisting.

As long as they can understand the pictures, Wang Yang can express the thoughts in his head to them, and they will be able to understand them in a short time, instead of having to do something repeatedly by themselves and struggling to express it in roundabout ways.

It allows everyone to express their thoughts and cooperate more tacitly, thereby improving hunting efficiency to a certain extent.

You can also draw certain hunting techniques on the wall to let them understand what is feasible and what is not feasible, and where there is danger and where there is no danger.

This will reduce the chance of death for children entering the forest for the first time and the chance of missing prey.

There was no way he would let go of such a multi-purpose thing.

But he didn't have much hope, so he always did it when everyone was free. If he didn't succeed, he would just do it for fun. Once he succeeded, there would be many benefits.

He was very excited now. He grabbed the expeller's arm, pointed at the painting, and kept asking: "Do you understand? Do you really understand?"

Seeing how excited Wang Yang was, other people gathered around him, pointing at the painting and shouting something with him.

Wang Yang thought to himself that they might think it was the first time he saw it, so he was as excited as they were.

So he picked up the branch and began to draw these four paintings on the other side, so that they would understand that the paintings were painted by me.

Everyone looked at the images he sketched out stroke by stroke, and they didn't know what kind of colorful world was formed in their minds. They looked at Wang Yang very excitedly.

Then he pulled him to the prey that still had half of it left yesterday, pointed at the prey and screamed, and then pointed at Wang Yang.

Wang Yang frowned: "You mean...I didn't kill this wild boar? Of course I didn't kill it. I wasn't with you yesterday."

At this point, Wang Yang hissed in confusion, as if he understood what they meant. They should have said, "You were not here yesterday, so why could you draw the scene of them hunting wild boars yesterday?"

In order to confirm this idea, Wang Yang pushed them to the wild boar, stood aside, pointed at them, and then pointed at the painting on the ground.

Sure enough, they became excited and shouted "woo woo".

Wang Yang thought to himself, it seems right, but they don't know how to express themselves by nodding yes and shaking head no.

But if this is the case, another question arises. The reason why they are excited is not simply because they understand the painting, but because what they see is their own memory.

And turning memories into the form of pictures was the first time they saw it, so they were excited.

There is also confusion about why Wang Yang could draw their memories even though he was not at the scene.

Doubts and novelty may be the reason for their excitement.

Wang Yang muttered: "It seems they have forgotten that I have participated in hunting many times."

Regarding the memory ability of apes, he once read a passage in a book, which said that apes have very incomplete memories and often throw away their weapons after hunting, only to make them again when needed later, resulting in a huge waste of labor.

At that time, he had no objection to this. After all, the ape-man's status in the forest was not high. This may be one of the reasons.

But when he came here in person, he found that the ape-man's memory was not as bad as he thought. In their childhood, they might make such mistakes, but when they grow up, they would hardly make such low-level mistakes.

Just like animals, no matter how low their IQ is, they will still polish their claws, even if those claws can easily tear apart prey.

Tools such as stone awls and axes, just like their claws, are sharp tools for survival that have penetrated deep into the soul and are indelible.

But here comes the question, why is it said that the ape-man's memory is not that bad, but not not bad at all?

Because their memories are more focused on terrain, animals, finding nests, and hunting, other things will be forgotten very quickly.

Otherwise, Wang Yang would not ask them to repeatedly identify animals they had recognized before every day.

In order to find out whether the images in their minds were based on memory or whether they could form images independently through reading, Wang Yang drew four new pictures on the ground.

These are also four similar hunting pictures, except that the tragic wild boar has been replaced by the tragic saber-toothed tiger.

Then he called everyone over and observed the expressions on their faces.

They looked at the new image for a while, with indifferent expressions on their faces, and then looked back at themselves calmly.

Sure enough!

As expected, they had no reaction at all to these four pictures, because they had never hunted saber-toothed tigers in their memories, and there was no corresponding image formed.

Although they did not achieve success overnight, Wang Yang was still very happy. He finally found a breakthrough and knew how to exercise their abstract thinking. The progress was huge.

The next thing to do is to train their memory skills.

Thinking of this, he did not waste time hunting, pushed everyone out of the cave, and let them go hunting.

A few days later, they captured another prey, and their cooperation became much more skillful.

At the same time, a few days also made them realize that hunting one prey does not require so many people, so they began to divide into two groups, each group of five people, staying in two places to wait.

In addition to the osteologist who thinks about catching fish every day, there are also several people picking wild fruits and hunting small animals on the outskirts of the forest.

So Wang Yang took out the barrel trap, handed it to those people, and let them understand the operation process of the barrel trap.

In this way, they can have enough time to pick wild fruits, and then they only need to check where the traps are buried after a while.

Now the food harvested by the tribe every day is almost twice as much as before. The abundance of food also makes Wang Yang more motivated to open orchards.

Every day I cut down trees, dig up the ground, dig out tree roots, and then plant seeds, and my life is prosperous.

But he didn't expect that just a few days later, a bigger surprise would appear.
