After walking around, he approached the bison with a thin stick, and the bison's "work" finally paid off.

"Did you understand?" Wang Yang raised his head and looked at everyone proudly.

Everyone nodded very seriously and gave a thumbs up: "This cow-controlling technique is very clever."

"Puff!" Wang Yang spit out a mouthful of old blood: "What a bullshit technique? I'm also teaching sword control!"

If it weren't for sure that they hadn't read online novels, Wang Yang would have scolded them for reading too many online novels.

He didn't care about the embarrassment of failing to show off, so he pulled them over and explained in a tactful way that he was arable land with pictures. He dug up the lower layer of soil to cover the upper layer, solving the problem of residual straw.

And a ravine was dug up to directly plant seeds, and the wheat would grow better next year.

Save time, effort, and everything is easy.

"So that's how it is." Everyone suddenly realized and praised Wang Yang again.

Wang Yang had no intention of talking nonsense with them, waved his hand and left here.

Here, a series of tool reforms and agricultural reforms ended successfully, and officially moved from the most basic agricultural era to the new agricultural era of slash-and-burn farming in one fell swoop.

To this day, he can finally say proudly that what is in modern times, we basically have it, and the great ideal of the new socialist countryside has been completed.

If you want to go further, you will get the heavy metal era, electricity, machinery, etc.

That is a distant future, and you don't have to think about it for the time being.

Wang Yang finally had the leisure to stop and rest, and at this moment, another good news came.

The pregnant women in the tribe gave birth. One after another, the population of the tribe surged to more than 700 in just a short period of time!

It makes people sigh and sigh. Once upon a time, did you ever think that the tribe could develop to this point?

What echoes throughout the tribe is always crying babies, crying during the day, at night, and crying all day long.

It was nothing, but it seemed that emotions would be contagious. When a baby cried, a few babies immediately cried, and finally all the babies cried together.

Sometimes I cried fiercely. It lasted for millions of miles, and a sad atmosphere swept around. Those who heard it were sad, and those who saw it cried, which moved the alpacas to cry.

Originally, the birth of a newborn is a very happy thing, and it is a day worth celebrating in the tribe.

It’s a bit like the Spring Festival in later generations. During that time, you can let go of anything and take care of your newborn.

Although Wang Yang forced this to do it at the beginning, in the days that followed, everyone took the initiative to help the pregnant woman.

This is closely related to the people's full food and clothing and intellectual development. Obviously, their emotions have become much richer.

However, there are so many babies born this time. Everyone felt deeply frustrated when facing the babies crying all day long. They couldn't bear it.

Not to mention taking care of them, I can't sleep well.

So everyone agreed to build a new big house alone in the distance and hide in it.

Everyone was full of motivation, and they stepped up their construction like a burning butt. They miraculously built everything within three days, regardless of whether it was firm or not, and they moved in directly.

Yes, Wang Yang is also among them.

Wang Yang, who was originally planning to take a break for a while to replenish his brain cells, was also quarreled with peace.

He was really afraid of these little ancestors. He shouldn't owe them anything in his previous life. Why did he repay him like this in this life?

On this day, there were another cry of shocking and crying from the big chain house opposite.

Everyone looked at the huge house opposite, looking at each other, discussing who to come to get food.

"Go, aren't you from the patrol team? You are the most powerful!" The orthologist pointed at a man.

When the patrol member heard this, he immediately stopped eating. After getting on the alpaca, he rode away to the distance, calling it patrol...

"Or why don't you go? You are so powerful that you can definitely keep those babies from crying." The orthologist pointed at the exorcist.

The driver took the forage and ran to the plowing land.

"Or why don't you go? You saw wood every day, and your voice is louder than a child's shouting. It's okay if you go." The orthologist pointed at Zhang San.

Zhang San glared at him: "Didn't you see me processing tools?!"

"If everyone doesn't go, can you still be hungry?" said the orthologist with a sad face.

Everyone also looked at the room opposite with lingering fear.

If it is just the baby on the other side who cries, it will not be able to give them such great lethality.

The worst thing is that the babies are very difficult to serve. I heard that they had collective incontinence last night and sprayed the whole house, and none of the women were spared.

This kind of problem is really harsh. Finally, someone suggested that the most difficult thing should be left to the most powerful person to do.

Wang Yang, who was thinking about making a toothbrush, suddenly felt tens of thousands of eyes focused on him, like cold needles piercing him on his back, making him shivering.

Turning his head, he saw everyone making a way out and leading to "Rome".

"Okay, you guys! I'll come here for everything! I'm just going to get some food. Are you as scared as seeing a poisonous snake?"

"There are just a group of babies on the other side. Can you eat you or what? Or is it a man! Or is it a handful of them!"

Everyone looked at their little brother and thought a little about what the relationship was with bringing the handheld and getting the food.

Then they covered their little brothers and shook their heads very seriously: "We don't bring you any more."

"Puff!" Wang Yang spit out a mouthful of old blood, he was speechless, and he was too shameless.

The tiger's body shook, his big hand shook, and said in a very domineering manner: "Look at how I came back with the food!" He strode to the opposite side.

As soon as the door of the granary was opened, the women who heard the sound immediately ran out of the other houses.

I saw them covered in shit and peeing, holding the crying baby, and rushing towards them anxiously.

"I...I'll go." Wang Yang's face turned green and closed the door of the granary with his hands. He let the women knock on the door and scream, but they just didn't open it.

The blade-toothed tiger seemed to have been stimulated, retreating with force and looking at the women outside in fear.

For the beast with a sensitive nose, the smell of shit and urine had already magnified countless times. It was a large nest, and it was even more odorous, and it was almost fainted.

After a while, seeing that there was no movement, Wang Yang returned to the big house opposite in shame with a few bags of food.

He raised his head and said to a group of "no ones" guys: "See, this is the manifestation of a pure man!"

Everyone admired it extremely.

Unfortunately, in the afternoon, everyone stepped into the house full of shit and urine under Wang Yang's forced. The reason was that they did a big cleaning.

Wang Yang knew the importance of maintaining hygiene, so he didn't care whether it was odor or not. He cleaned up the big house and looked brand new.

Everyone wiped their sweat and expressed their relief, and finally they were refreshed.

So, the next day they cleaned it up again.

On the third day, they cleaned it up again.

After a month, everyone did nothing and were cleaning every day, busy helping the group of little kids wipe their butts, speechlessly choking.

After finally experiencing the most uncomfortable two months, everyone was idle. At this moment, a good harvest began in the orchard, so Wang Yang asked him to come over to help.

For two months, I basically did nothing, which was a waste.

In fact, Wang Yang thought about whether to cut a piece of animal skin and acted as a diaper for babies. Later, when he thought of so many babies, he didn't know how many animal skins he had to consume in a day and where he could afford them, so he gave up this plan.

And on this day, he finally developed the first toothbrush!

It's really a toothbrush, the handle is a wooden handle, and the brush head is made of fiber. It is very soft and does not have the hardness of later plastics, and it tastes great when brushed.

But because it is too soft, the effect will not be as good as that of later generations.

It doesn’t matter. Five minutes is not enough for future generations. Let’s just use ten minutes! Everything is missing, but time is not lacking!

Speaking of this, he was still inspired by the ancients.

As early as the late Tang Dynasty, China had tooth cleaning tools. At that time, we soaked willow branches in water. When we needed to use it, we took it out and bit it open, and the fibers inside would spread out.

This is how the old saying "Checking the wood in the morning" comes from.

Later in the Southern Song Dynasty, there were shops that specialize in teeth making, made of bones, bamboo, wood, horns and other things, which were similar to modern toothbrushes.

Wang Yang thought about the things like bone, bamboo, wood horns, which were not rare, but it was too difficult to make. He directly switched to fibers, which was a good effect.

"I'll wash, wash, eat sugar..."

In the next period of time, he pulled a team of carpenters left by Zhang San, processed them into thicker fibers, and then made them into toothbrushes.

This is a meticulous job, so it can't get up quickly. It took a long time to get a hand and promote it. Whoever wakes up in the morning will not brush his teeth and will not be allowed to eat.

Don't brush your teeth at night, take your baby!

It was finally easy for everyone to develop the habit of brushing their teeth.

On this day, he brushed his teeth for ten minutes and grinned: "It's getting whiter and whiter, and this image is getting taller and taller. Finally, I can eat candy with confidence..."

That’s right, he invented that the toothbrush was not because he paid more attention to oral hygiene, nor to make his teeth white, but to eat candy!

I have been wasted so much effort to make toothbrushes and let everyone brush their teeth just to eat candy!

If it weren't for the toothpaste, he would have spent a lot of time and...eat candy!

He waved his hands to everyone excitedly and solemnly promised: "Next time I come back, I will make the steamed buns more delicious!"

Everyone was so moved that they cried silently, saying goodbye: "Can you not mention steamed buns?"

Without further ado, Wang Yanghao led a team of men to the forest. When he passed by the baobab tree, he cursed again.

"Think about it yourself, how many years have you raised? Is this growth efficiency worthy of me? Is it worthy of the general public? Is it worthy of the motherland and nature?!"
