People in Datang have been expelled from school

Chapter 1101 Building a House in the River
Kong Yingda came to the academy's office, which is where the master of the academy usually works.

Seeing Kong Yingda coming, Li Chunfeng quickly got up and said, "Old Master, how are you doing today?"

Kong Yingda put away the pamphlet and said, "Today is also a very fruitful day."

Taking Kong Yingda to his room, Li Chunfeng said: "On weekdays, our masters live in the academy."

Kong Yingda walked into Li Chunfeng's room, seeing the dense formulas written on the wall, which seemed very permeating at first glance.

Seeing Kong Yingda's expression, and then looking at his room, Li Chunfeng smiled awkwardly: "The shabby house has not been tidied up for some time."

As Li Chunfeng was speaking, he tidied up in a hurry and said, "Why don't you say hello to His Royal Highness Wei Wang, there is still a vacant house in the academy, and the old master can live here too."

Kong Yingda waved his hand and said, "The status of an old man is not suitable for living in an academy."

Li Chunfeng heaved a long sigh. Thinking about it, Kong Yingda's identity also represented Confucianism. If Confucian children knew that Kong Yingda lived in the academy, they would be in trouble again.

Looking at the formula on the wall, Kong Yingda asked, "What are you calculating?"

Li Chunfeng said with emotion: "I saw a symbol in Li Zheng's Mathematics book before, and later Da Niu said that this symbol is pi. This number is bigger than three but smaller than four. There are countless numbers after [-]." It is said that it is a formula that can never be counted."

Kong Yingda said, "Really?"

Li Chunfeng sighed and said: "It has been three or four years since I came to Jingyang. I have been calculating this pi for the past two years, and I have counted it to four. At present, I have not counted it to the end. Every time I go to bed, I spend a few pi. The hour is counted, but it is still not finished."

Kong Yingda asked suspiciously, "Is there such a thing?"

Li Chunfeng nodded and said: "When I was young, I followed Yuan Tiangang and saw this algorithm in other classics. There were predecessors who calculated it a long time ago, but it is not as clear as Li Zheng."

While talking, a group of children ran out of the academy together.

Li Chunfeng said: "Da Niu and others are going to conduct experiments again today, do you want to go and have a look together?"

Kong Yingda nodded and said, "That's fine, that's fine."

The middle-aged Li Chunfeng and the gray-haired Kong Yingda walked out of the academy together.

Following behind a group of children, they came to the river in Jingyang.

Kong Yingda also saw Li Shimin standing here.

Li Chunfeng and Kong Yingda stepped forward to salute together.

Kong Yingda asked curiously, "Your Majesty also came to see the experiment?"

Li Shimin just said indifferently: "I just came here for a walk."

Many people also came from the other side of the village, the leader of these people was Yan Liben.

Following Yan Li himself was a thousand recruited apprentices.

These apprentices have been in Jingyang for a month.

Seeing Yan Liben's great momentum, Li Shimin didn't pay much attention, and continued to observe Daniel and the children.

Yan Liben said to the craftsmen: "Most of you have mastered the technology of water pumps. Everyone's purpose is to learn the technology. Next, you can take a look at this experiment. If you want to leave after reading it, take it tonight." You can go home after paying your wages, and those who want to stay can continue to stay and learn skills."

Both sides of the river were full of people.

Everyone stared at the situation in the river.

A boat floated up from the upper reaches of the Jingyang River.

The boat is very small, just a very small fishing boat.

On board were Daniel, Di Renjie, Pei Xingjian, and Li Zhi.

As the boat slowly arrived in front of everyone.

Take a closer look at the rear of the ship and there are very thick stone pillars.

Li Shimin wondered: "How did this stone pillar float on the water?"

Li Chunfeng explained: "I have seen the drawings in the research institute. This stone pillar is actually hollow and poured with mud. The reason why it can float is because there is wood under the stone pillar."

Li Shimin took a closer look, "It's true."

The four children swam to one end of the four pillars.

Li Shimin had already approached the river without knowing it, and he couldn't hide the curiosity in his eyes. He took a closer look at the stone pillars that were still connected together with chains.

Following Daniel's order.

The four of them worked together and pulled out the rafts at each end of the stone pillar.

The water immediately flowed into the hollow stone pillar.

Slowly the stone pillar began to sink.

The four children also followed the stone pillar downstream.

When one end of the stone pillars sank completely, everyone saw that the other end of the four stone pillars was a flat platform.

When the stone pillar stood completely in the river, Daniu, Li Zhi, Di Renjie, and Pei Xingjian also swam up, as if to confirm that the stone pillar could not be pushed by swimming in the water.

Li Shimin observed that the stone pillar seemed to be unable to be pushed.

Looking at Li Chunfeng, Li Shimin said: "What's going on, standing on the river like this?"

Li Chunfeng brought a bowl from the side, turned the bowl upside down in the ditch and said, "Your Majesty, please see, because of the water pressure, it is difficult to lift the bowl upside down in the water. The greater the water pressure, the more difficult it is. The depth of the Jingyang River That’s right, so once the stone pillar is suppressed by water pressure, ordinary people can’t push it at all, this is the principle.”

Li Shimin nodded slightly, but there was still doubt in his eyes.

The stone slabs that have been poured are transported to the river.

Using those four pillars as fulcrums, the stone slabs began to be laid.

An hour later, a platform was built in the river.

Li Shimin simply sat down and continued to watch, his brows furrowed more and more.

Half a day passed, Li Shimin was eating the meal brought by Wang Ding, and the children were still busy. It turned out that they were going to build a house in the river.

After reading for a while, after eating the rice in the bowl, Li Shimin picked up the science book on the side and studied the relationship between water pressure and air pressure.

By the evening, the houses built in the river had already taken shape.

Li Ji, who was wandering around the village, came up and said, "Is Your Majesty still here?"

Li Shimin pointed to the river and said, "I didn't expect to build houses in the river without filling the river."

Li Ji said: "That's true. There is no need to fill the river and it will not affect the downstream. It is also very easy to build houses in the river."

It was getting dark soon, and the children of Daniel Li Zhi also went ashore.

Seeing Li Shimin, Li Zhi quickly ran over to salute, "Why is the father here?"

Li Shimin walked back with Li Zhi and said, "Is this house solid?"

Li Zhi said: "In fact, we have also treated the bottom of the river, and it is tightly fastened, and it is still very strong."

Li Shimin nodded slightly and said: "It turns out that you have also tampered with under the river."

Li Zhi explained: "We also built a corresponding platform at the bottom of the river, otherwise it would not be so strong."

After sending Li Zhi back home, Li Shimin simply came here too.
