I broke out of the grave and was broadcast live by Yearning

"So the master-student relationship just mentioned is not wrong."

Everyone nodded after hearing this, which means that Lu Ban is indeed Ye Xuan's apprentice, but Ye Xuan passed it down orally, and he always made out all the things Ye Xuan said.

"Actually, some interesting stories happened between me and Xiao Lu back then."

Ye Xuan smiled when he mentioned Lu Ban, and it was obvious that he was very satisfied with Lu Ban.

"What happened to Grandpa Ye? Tell me quickly."

Peng Peng couldn't wait any longer, what he liked most was listening to Ye Xuan tell stories.

"Then let me think about it first."

Ye Xuan knew that there were many things that happened between him and Lu Ban, and he and Lu Ban were also the ones who stayed together the longest.

But it will be really difficult for him to speak now.

The netizens in the live broadcast room couldn't wait, they really wanted to know what happened between the two characters Ye Xuan and Lu Ban.

Chapter 254 Ye Xuan Instructs Luban

Ye Xuan cleared his throat, and then slowly told about Lu Ban.

At that time, the water that everyone drank was basically well water.

According to legend, the first person to dig water out of the ground was Emperor Shun.

Because he discovered that water can be dug out from the ground, so most of the problems were solved, and everyone didn't have to go to the river to fetch water every day.

But in fact, there are other people who drill deep wells in mountainous areas.

The wells drilled by Emperor Shun were shallow water wells in relatively prosperous places, but the wells drilled by Lu Ban were deep water wells in mountainous areas.

And it was Ye Xuan and Lu Ban who went to the mountain together to dig out the deep well.

"So what happened in the first place?"

Sister Zifeng continued to ask, now basically every household can see these wells.

And everyone knows that Emperor Shun was the first to dig water out of the ground, so it is natural to think that Emperor Shun also discovered the well.

But after hearing what Ye Xuan said about this incident, everyone realized that this is not the case, and history will have deviations.

"Since you want to hear it so much, let's talk about the deep water well."

Ye Xuan cleared his throat and said the matter.

"At the beginning, human needs for water depended on rivers and lakes. If there was no home, no hustle and bustle, then water was obtained through the ground. At first, the wells were very careless, with big mouths and small bottoms, not square or round, at best It can only be regarded as digging a well when thirsty."

Ye Xuan smiled when he said this, he felt a little distressed when he saw people drinking water like this.

The water produced in this way not only tastes bad, but is also extremely susceptible to contamination.

If you are not careful, the water in this well will be undrinkable.

"Lu Ban and I ran around the streets and alleys when we had nothing to do. We saw many people's wells like this, so we thought about how to make people drink deep well water. If we build a deep well, it will not be polluted. And the quality of the water dug out is also good.”

Ye Xuan continued to speak, with a smile on his face.

"I just told Lu Ban about it. I didn't expect that kid to study it carefully after returning, and finally ran to me excitedly and said that he figured it out."

After Ye Xuan said this, the smile on his face grew stronger. It was obvious that he was very satisfied with Lu Ban.

"I told him at the time that we could use pottery rings to drill the well deeper. This kid went back and closed the door to delve into it for three days and three nights, and then passed his idea to me."

Speaking of this, everyone felt a little surprised. I didn't expect that Lu Ban was so concerned about these researches at that time that he was able to lock himself up and study for three days and three nights. This spirit is really admirable.

And after Lu Ban drew the sketch, Ye Xuan modified it a little bit.

After seeing Ye Xuan's modified sketch, Lu Ban was very excited and insisted on taking Ye Xuan to the mountain to experiment.

"I was really too lazy to go, but this kid actually said that if he didn't go, he would carry me away overnight, so what could I do, I had to accept my fate and go up the mountain with him."

Ye Xuan waved his hand helplessly, everyone seemed to be able to imagine the scene at that time.

And Lu Ban was very careless when he went up the mountain. He is a careless and careless person in life.

The hand was accidentally cut by a leaf, and some blood came out.

"At that time, I bandaged him up, and then I saw that the leaf's jagged shape was so sharp that it could scratch a human hand. I told Lu Ban that if it was made into a tool, wouldn't it save some effort? gone."

And when everyone heard this, they all understood that Ye Xuan also had a part in the saw.

"It's simply too unreal."

Sister Zifeng nodded after hearing this, but she didn't expect that Lu Ban and Ye Xuan accidentally found the saw when they were digging a deep well.

This should be the legend, killing two birds with one stone.

"Although he is careless in life, he is very rigorous when dealing with things. I like this aspect of him the most."

Ye Xuan was a little eloquent when talking about Lu Ban.

"Let's talk about digging deep wells. When he got to the mountain, he would dig wells according to the sketches he drew. I would remind him a few words from time to time."

"In the end, it was really beaten out by this kid."

Lu Ban's well-drilling technique at that time was very practical.

And it is precisely because of this that there are stone wells cut out of stone, brick wells built with bricks, pottery wells connected with collars, gray wells plastered with sand and ash, and wooden wells framed with wood.

It was not until the end that people understood how to build well platforms to prevent the inflow of sewage, and build well pavilions.

Later, people gradually became smarter, and this practical and beautiful water well appeared.

After Ye Xuan finished telling the story, everyone suddenly realized.

"So that's the case, so we can drink deep well water now, shouldn't we thank Master Lu Ban?"

Peng Peng said half-understood, Ye Xuan also nodded after hearing this, it is indeed the case, if there is no Lu Ban's research spirit at that time, it would probably be hundreds of years later for people to drink deep well water.

"However, we not only want to thank Lu Ban, but also Ye Xuan. If he hadn't put forward so many suggestions and ideas, Lu Ban must not have found a way and a way out."

Teacher Huang also added on the side, and everyone applauded after hearing this, with the most sincere respect and gratitude to Ye Xuan in their hearts.

"What's there to say? By the way, the pulley you see now is also invented by Lu Ban."

When Ye Xuan mentioned the well, he suddenly thought of the current windmill.
