There are three unfilial pieties, and no queen is great.

Not having a child seems to be very unfilial, but then again, there is no such concept in this era, and it seems that there is nothing wrong with not having children.

He took a piece of wood for the little guy to eat, and the little guy took it slowly, gnawing gently, the movement was weak and slow, and he didn't know if it was dying after living for so many years, Wang Yang could feel that it was getting more and more sluggish.

It dawned on him that he had been stolen for five or six years, and that in those five or six years, all he had had been doing was damn words and books, and not paying attention to what really needed attention.

For example, take care of the little one's life and help him have an offspring?

It's funny to think about it, even if you catch a female mouse, how can this arrogant little guy look at it? It's nothing more than a brick.

Exhausted emotions overwhelmed him, he felt a little weak, a little sleepy, a little not wanting to move, in the dimly lit room, combing the little one's silky hair.

It didn't move, and it enjoyed it with its eyes closed, but unfortunately its mouth was still moving, gnawing on the wood.

"Wow!" He lay on the bed with copper springs, and his body bounced slightly, and there was a strange feeling of returning to modern times for a moment.

He didn't get involved in making springs, but when he was talking about reaction, he drew such a thing, and the students went to make springs.

It not only makes pure copper springs, but also makes bronze springs, white copper springs.

Of course, the latter two are too stiff to make decent springs.

Even copper springs are defective products with weak elasticity, and they are not comparable to modern springs.

But that didn't stop the enthusiasm for spring-making. When they heard Wang Yang say that it could be used on the bed, they made a spring bottom.

It is then woven into cloth from hemp. I made a bed frame and stuffed some chicken and duck feathers into it. The messy things were sewn up, and finally sent to Wang Yang.

It's a luxury, and only a limited number of people sleep on one.

They also realized that they didn't have to sleep when they made it, so they simply stopped making it.

So I used the spring in other ways and made a small hand crossbow, and found that the elasticity was not good, the power was too small, and I couldn't hurt people when I shot it. Full of melancholy, pondering how to improve and increase the elasticity of the spring.

The clever man pondered the reaction force from somewhere else, and one guy took a piece of wood and tried it, and got the reaction force, so he thought that if the tree was big enough, would he get more reaction force?

He found Wang Yang, who didn't say a word and directly drew the structure of the bow. Then give him a detailed description and let him try to build it.

There are countless things like this, Wang Yang only needs to be a designer with peace of mind and draw a drawing. Let them test it, and add at the end that you can try to improve it.

No matter how powerful a person's brain is. It's never as good as a bunch of human brains, and he knows it.

To broaden their horizons. Naturally, Wang Yang will be the invention of later generations. Make up a book and let them read it for themselves, and whoever thinks they might be able to make it, then make it, without worrying about wasting materials.

Since then, tribes have invented extremely quickly, and all kinds of objects have been built at a rapid pace.

Unfortunately, in biology and chemistry, their progress is relatively slow, and many materials are difficult to find.

Thanks to geography, people know that certain materials exist in a certain environment, and they plan to look for them there.

There is already a group of people who are planning to go on expeditions all over the world in search of these things.

Wang Yang did not approve it because he did not know the situation of the tribe today.

The door was slowly pushed open, and the bright sunlight shone on Wang Yang's white coarse cloth robe, so bright that it seemed that those clothes were flashing.

The caftan has wide cuffs, like the ancient caftan to the feet, its inner hollow is empty, as soon as the wind blows, it will drill into the wide cuffs, the whole body is cool, very comfortable.

It's a nice design, it doesn't expose the skin to strong UV rays, and it doesn't get too hot because you're wearing a piece of clothing, which is much more comfortable than animal skin.

"Woo!" As soon as he came out, some people beckoned to greet him, some of them learned from Wang Yang to wear long robes, some still wore animal skins, and some were shirtless, and there were many kinds of them.

In fact, there is no aesthetic concept, and they don't necessarily think that they look good in these clothes, like hunting teams, and people who mine clay and do carpentry.

These people definitely don't like to wear this kind of long shirt, because it is too restrictive to move, and people who work do not wear tops, and they wear shorts on the lower body, because the lower body is very fragile and has to be protected.

Dressed like Wang Yang, they are basically pregnant women and students who don't need to work, pregnant women understand very well, and those guys who are going to school are purely imitating Wang Yang.

As a result, he unconsciously formed a clear identity trait, and his current identity can be distinguished from his dress.

When I climbed up to the roof, I saw the vast land of fertile fields, and in the middle was the area where people lived, and there were no less than a hundred buildings here, all of which had been built in the past six years.

A dozen black smokes emitted from the crowd as they walked through it, and it was a burning bonfire that would not be extinguished even during the day.

A civilization was born in such a madness!

Wang Yang finally smiled with satisfaction, he felt very happy, very happy, very happy, the pride and pride that could not be explained in words, filled his chest, and he couldn't help but spread his hands and bathe in the beautiful scenery.

There are not very many people on the streets, and most of them still need to go to work and contribute to the tribe.

And when you can see him on the street, don't you look at him a little suddenly, why is it suddenly? Because I don't know him......

They knew that his name was Wang Yang, and they knew that the tribe was led by him, but not many people were familiar with him, and they had only heard his story from other adults.

Those stories amazed their rising stars, and they admired him immensely, regarded him as a myth, and in some cases, they had infinite respect.

But they don't know what Wang Yang looks like, and the more he has lived in the past two years, the more Wang Yang has lived in seclusion, because what he needs to be responsible for is no longer a course that teaches everyone directly.

These courses are represented by others, the first to the second and the second to the third.

As for Wang Yang, it is really rare to see such an honorary principal.

What he needed to do was to do it in a big house, to write all kinds of books, to spread knowledge, to expand his knowledge, and to have access to less than ten people, all of whom were the most respected figures of the tribe.

As for the second-in-command, third-in-command, and fourth-in-command, the status is also very high, but they are not the highest rising leaders, but they can't see Wang Yang.

Now Wang Yang has finally completed the cumbersome education, and he has once again appeared in the eyes of everyone.

"Woo~Woo!" A teenager called out, he recognized Wang Yang, or rather, he didn't know Wang Yang, but all the records and pictures about Wang Yang had a big mouse on his shoulder.

He recognized the big mouse.

"Woo~Woo!" Another man called out, and he recognized the big mouse.

More and more people gathered in this direction, looked at the man bathed in the sun, and let out a cry of surprise.

"Woo~Woo!"

"Woo~Woo!"

"Woo~Woo!"

The roar of the mountains and the tsunami-like cries of the mountains joined together, drowning the world and the world.

Wang Yang slowly opened his eyes, looked down, and saw this sea of human heads full of surprise, admiration, curiosity, and curiosity.

Faces were familiar or unfamiliar in front of him, exclaiming below him.

The exclamation suddenly turned into cheers, shaking the heavens and the earth, everyone waved their hands, and saw the leader of the dragon who saw the head and the tail, and only appeared in the story, and only felt a burst of joy.

Wang Yang smiled faintly, his pores dilated, as if he had been washed by the sun, and gently pressed his hand, and the audience was immediately silent.

Falling below, Zhang San squeezed out of the crowd and came to Wang Yang, smirking hehe.

"Why are you smiling like that? It's not like you haven't seen me. Wang Yang took a pen, took a blank book, turned the first page, and wrote what he wanted to say.

Zhang San also had a book in his hand, and half of the book was already written, so he turned to a blank page and wrote: "You haven't been out for three months, and you haven't been out during the day for six months." ”

"Really?" Wang Yang smiled, but he didn't remember this, at this time last year, he had already finished teaching all the courses, and he was making up other books and entering the finishing stage, so he naturally stepped up his work every day and night.

And since the advent of pen and paper, there have been calendars, and people have begun to count the number of days, so as to calculate the efficiency of work, and so on.

The convenience it brings is something that many people never dared to think of before.

"This time, I'm not going to hide in that room again, just like I used to be." Wang Yang wrote in the book easily, and suddenly saw a wrinkle on Zhang San's forehead, patted him lightly on the back, and didn't say anything.

"That's great!" Zhang San was very emotional, for the changes in the tribe, he saw the changes bit by bit, and the role of those knowledge was simply amazing.

In just a few years, the tribe has developed rapidly, and all kinds of tools have emerged one after another, and many new gadgets he has not yet understood.

He didn't know how Wang Yang had this knowledge in his head, only that Wang Yang was now trying to write more knowledge.

Thinking of this, he felt that no one else should disturb him, so he made a rule that whoever passed through here should be light and not to make a noise.

It's a pity that Wang Yang didn't think so much at the beginning, the house he chose was very remote at that time, but as the house was built more and more, it became the center.

The street was quite deserted, and people had to take a detour if they wanted to get there.

Wang Yang doesn't know much about these, but he doesn't see any movement outside every day, and he can guess some. (To be continued......)
