Yao Chonghua and Shen Yu Lei together to help Bi Bao go home, Bi Bo's Bi kiln is not far away, to say that Bi Bao is not a noble, but the prestige is still very high, he is the chief of Bi Bao kiln, Dongyi will make pottery a lot of people, but the failure rate of making pottery is also very high, the control of temperature and time during the production is not everyone can be flexible to master, Bi Bo is an expert in pottery, very respected, he has given Gao Tao advice many times, otherwise Shen Tu and Yu Lei will not call out the name of Bi Lei at this moment.

There are a lot of people in the kiln, there are thirteen disciples who can make pottery alone, plus farming and female dependents, young children, there are more than 30 people in total, this mouth has to eat, he is not under pressure, but he is already an old bone, and he can't do much heavy work, otherwise the person who went out to exchange goods today would not be him.

Bi Bo sat in the courtyard and asked the little disciple to lead the sheep to the fence, Yao Chonghua and the three of them sat around Bi Bi and listened to Bi Bo's story, Bi Bo has lived for more than seventy years, and he is a very long-lived old man, and most of the old people of his age have gone.

He had traveled all over the world and knew many magical things, and in his spare time, children from the neighborhood would come to listen to his stories.

Yao Chonghua thought that since Bi Bo had been to many places, he should know that there was a Yu family, so he asked Bi Bo.

"You're Yu?" Bi Bo thought about it carefully and replied: "I know, I went to that place twenty years ago, it was a declining aristocratic tribe, it was originally a descendant of the Yellow Emperor, but now it has become the territory of Dongyi, at the junction of Huaxia and Dongyi. ”

"Is it far from here?"

"Far away, are you from the Yu clan?"

Yao Chonghua nodded.

"Your father is a fool?"

Yao Chonghua nodded again.

Gazing touched Yao Chonghua's head, and the old man was relaxed and plain: "Twenty years ago, when I came to Youyu's family, Gazu received me warmly, if you are his son, then you are the eighth grandson of the Yellow Emperor and the sixth grandson of Gaoyang's family." ”

Yao Chonghua frowned, he didn't know that his tribe still had deep roots.

In Bi Bo's opinion, Yao Chonghua is just a child, and he is not sensible yet, "You don't have to think so much, from what you said just now, I know that you are a reasonable person, but you are much better than your father......" Bi Bo's tone paused, as if he felt that it was not good to say Lao Tzu in front of other people's sons, "I have an old bone, don't mind, I'll tell you the truth, if you can have a Yu family, I will persuade your father more." ”

Bi Bo seemed to recall, "There is a big river on the side of the Yu family, frequent floods, more water networks than Longshan, the land is relatively barren, there are fewer places to cultivate, and the annual harvest is often beyond the means, I arrived at the time of the Yu family, the flood only crossed the border not long ago, but your father slaughtered a farming cow for me when I didn't know it, just because I am a noble man from Longshan, I am grateful for his enthusiasm and taught them the art of pottery, but I don't agree with his practice in my heart, it hurts their livelihood too much." Huaxia pottery in general, there are Yu clan is classified into Dongyi is Dongyi people, Lao Su will naturally not be stingy with craftsmanship, but Huaxia hurts the fundamental bad habits but must not. ”

Bi Bi whispered to them to retrace the past, from his words, combined with his vague memory of ancient history, Yao Chonghua also understood, Dongyi and Huaxia since the first war, each other do not come to each other, close to the geography because of the conquest between the tribes or integration or separation, after hundreds of years, some of the original Dongyi tribes have become Chinese, and some Huaxia has become Dongyi, although the two independent regimes are still resisting and disgusting each other, but the blood relationship has been unable to distinguish whether it is Huaxia or Dongyi.

At the same time, Yao Chonghua also realized a very important information, Shun - Yu Shi - Yu Shun - surname Yao Chonghua - Chonghua - Chonghua, Yao Chonghua looked at the clay pot filled with water reflecting his own shadow, under the blue sky and white sun, those eyes that were different from ordinary people were such obvious features.

Tang Yao, Yu Shun, Xia Yu, the owner of his own body may be the legendary ancient holy lord, one of the three emperors and five emperors Yu Shun.

Yao Chonghua himself was surprised, but that poor young man was already dead, how to do the Holy Lord? Still is...... Yao Chonghua, who is now the soul, will complete this mission?

Yao Chonghua himself doesn't know, he is a person from the future, he came here to mess up time and space, and history may change, maybe Emperor Shun will disappear with it, and now he is just taking one step at a time.

At noon, Yao Chonghua and Shen Tu Yulei did not go home, they nibbled a steamed cake here in Bi Bo, and followed Bi Bo into the Bi Bo kiln, Bi Bo is now inconvenient to move, so he commanded the three children and his disciples to clay pottery, these dirty mud can be kneaded into various shapes, Yao Chonghua went to the grandmother's house in the countryside when he was very young and would roll in the mud, and the best thing to pinch was a small earthworm.

Shen Tu and Yu Lei are more familiar, Yao Chonghua is not good, you are just because he is younger than them, and before that, he only saw someone on TV pulling embryos, these clays are suitable for making pottery, and the clay needs to be moved to the mountains on the outskirts of the city, which is time-consuming and laborious, so they are all cautious, after all, they are not skilled, for fear of doing it badly.

Bi smiled kindly, and didn't want to treat his disciples like that, so he let him play casually.

Yao Chonghua observed the pottery embryos that had been prepared to enter the kiln, and found that most of these were small clay pots and pottery bowls, which could hold some oil and salt, and the slightly larger ones could hold rice, and the largest one was a rice cooker, no matter how big it was, Yao Chonghua looked up at the cave where the disciples were adding firewood, and it didn't look small, how to make the pottery so small?

Yao Chonghua has not forgotten the story of Sima Guang smashing the tank, the water tank can drown a villain, and his grandmother's house also has a big water tank, but because every household has tap water, he is idle at the gate to catch the rainwater.

If there is a large tank of water, it may be possible to store more water on a regular basis, so that there will not be clean and drinkable water after the flood has passed.

With this idea, Yao Chonghua also wanted to seek some welfare for this primitive society, if they lived well, maybe China's borders would be wider in the future.

But how? Yao Chonghua looked around, it seemed that all the tools that could be used were here, but they were still small.

Yao Chonghua asked Bi Bo: "Old Bi Bo, why are the objects made here small?" Isn't there a big one? ”

Bi Bi looked at Yao Chonghua, who was humble and puzzled, and replied: "It is difficult to make embryos from large pottery, even if five people do it at the same time, it can't be done, and forcibly putting it into the kiln is a failure." ”

Yao Chonghua then thought that the tools for making pottery were limited now, and the pottery embryo of the water tank could not be made at all, so did he give up like this?

Of course it can't be, Yao Chonghua is not such an easy to give up character, since there is no kiln, then go out and see, all human things are derived from nature, there must be a way to solve it.

Yao Chonghua came out of the kiln room, and saw a big tree stump next to the kiln room, these tree stumps were originally used as firewood for the kiln, and some of them had been split, Yao Chonghua thought of a good idea, but since he was a child now, he still needed the help of adults, so he turned around and went into the kiln room, squatted down in front of Bi Bo, picked up the pottery fragments on the side, and drew them on the ground.

He painted a water tank, "Lao Bi, please see, I painted a water tank, don't look at the small painting on the ground, but what I said is to make such a big pottery, not a small clay pot on the ground." He can be used to hold rice, but it can also be used to hold clean water. "Draw the volume of some water tanks with your hand to the maximum.

Bi Bi frowned and looked at the things painted by Yao Chonghua carefully, felt that it was impossible to realize, shook his head and said: "I said that you just asked what the big pottery tools do, it turns out that I thought about this, I also thought about making big pottery before, but it was too difficult, and five or six people couldn't help it." ”

In the face of Bi Bo's denial, Yao Chonghua was not discouraged, there was no embryo pulling machine, ten people were difficult to control, but this was not the method he thought, "People can't help themselves, then don't use people to help, we can make some tools to make up for the lack of labor." ”

Bi Bi looked at Yao Chonghua's confident appearance, and suddenly felt that this kid might really have come up with a method, which was something he wanted to accomplish all his life, and asked excitedly: "Chonghua Xiaotong really has a way?" ”

Yao Chonghua still squatted on the ground and drew a mold of a water tank, "The water tank is very large, and the wall of the tank is very uneven and easy to collapse. ”

Bi Bi saw that Yao Chonghua's approach was indeed a lot less labor, and it was indeed feasible to build up the cylinder wall with wooden planks, and when he heard Yao Chonghua's question, he blurted out without even thinking about it: "Is it okay to fish gelatin?" ”

Yao Chonghua doesn't know what fish glue is, anyway, it can be used, "and the inner wall of the water tank, we can put a large tree stump in the middle, if the tree stump is not big enough, you can cut several tree stumps into a circle, you can still do it, and then we can fill the middle of the wood chips and tree stumps with clay, and then beat and squeeze them vigorously, and after the pottery embryo is finalized, the wood chips and tree stumps will be removed, and a whole large pottery embryo will be available." ”

Many modern industries use molds to mass-produce goods, although Yao Chonghua has not done it before, but the principle is like this.

When Bi Bo heard that it was feasible, he couldn't wait to get up and want to try it, but his legs and feet were inconvenient, so he could only call his apprentice Jiu Yi to help.

According to Yao Chonghua's method, Jiu Yi and the older Shen Tu were assembled together, Yao Chonghua and Yu Lei helped to get small things on the side, and soon sat out the water tank model, Bi Bo looked left and looked, and couldn't put it down, looking at Yao Chonghua is also more and more pleasing to the eye, and boasted again and again, Shen Tu and Yu Lei didn't know what Yao Chonghua said about this water tank model, but to be praised by Lao Bi Bo like this, he must have done something amazing, and looked at Yao Chonghua with envy.

The disciples of Bi Bo came to watch, the model was already ready, or poured clay into it, and Jiu Yi compacted the clay with his hands on it, Yao Chonghua felt that what was the use of pressing with his hands? It was not strong enough, so I found a wooden stick and beat the clay hard to make it look firmer.

Shen Tu Yu Lei also followed the wooden stick to beat it, it took a long time for a few people to do it, this time it was already evening, and it would take a few days for the pottery embryo to be shaped before removing the wood chips and tree stumps, but this was already a very happy thing, the disciples of the Bi Kiln were very happy, and discussed on the side what this water tank would look like, "If it is done, maybe it can be filled with water for five days, so that we don't have to pick it up little by little every day." ”

"That's not it, if I can make a few more, I will definitely carry one home, when the flood comes, there will be a tank in the tank, which will be enough for the family for a few days."

"Yes, that's a solution to an urgent need."

A few children are bouncing around the water tank mold, so unhappy.

Bi Bo's already excited mood was infected by the children's laughter, and he touched his beard and laughed loudly.

Yao Chonghua is also very happy, he couldn't serve the motherland before, and now it's a good thing to be able to do something for the people in the world, Shen Tu and Yu Lei took his hand and asked him to dance together, and he didn't care about his soul in his twenties, and enjoyed the joyful atmosphere together.

At this time, Gaotao, who had been busy outside all night and day long, appeared in the Bibi kiln with a gloomy face.
