The Prodigal Son of Zhenguan

Li Fu had never imagined that the three children would eventually work on the waterwheel.

Originally, after the canal on the farm was repaired, the waterwheel had to be put up, but later the matter was put on hold. First, the canal was right next to the fields, and they thought they would just make do with it for a while.

Second, there was so much work on the farm, and they were desperate to make money, so the matter was put on hold.

Last winter, there was no work on the farm, so they built two waterwheels and set them up by the river.

In spring, when there was little water, they pulled water from the river into the canal, which ensured water for spring farming before and after the rain.

When the waterwheel was put on the canal, the water could really be pumped directly into the fields.

That would save trouble.

But as for the current traditional waterwheel, the efficiency is still a little bit lacking, and it can be improved. Li Fu has also thought about this, otherwise, can he just look up books?

How can a person who gets sleepy when he sees the words in a serious book take the initiative to read a book?

This is really useful.

It's just right, let the three children think about it, just treat it as a way to coax the children.

Li Fu lay on the recliner and continued to read his leisure books. Whether he could read it or not was another matter. Anyway, he was idle.

The three children sat on the wooden steps and studied and flipped through the two books.

For a moment, the scene was very harmonious, and both adults and children looked diligent and studious.

Until the sun set in the west, the sky gradually darkened.

It was time for dinner, and Lao Zhou came to the yard and told Li Fu that dinner was ready in the hall.

Li Fu stood up and handed the book in his hand to Xiao Tao.

"Let's go, it's time for dinner." Li Fu said: "Studying knowledge is not a one-day or two-day effort. There is plenty of time. Eat first. Health is the capital of study."

Li Fu collected their books and took them to the front hall to eat first.

The book was somewhat obscure and difficult to understand for their age, so it was normal that they didn't find anything for half a day.

While looking for the waterwheel, they could also take a look at the other contents in the book.

The meals in Li Fu's house were of various kinds and tasted good. Both the children and the older people like Lu Deming were very active in eating.

After all, the children were easy to deal with. If they wanted to eat something in the future, they just needed to send someone to tell Li Fu, the uncle, and Li Fu would definitely take them to eat.

But Lu Deming, like Yan Lide, knew that it would be difficult to enjoy such delicious food after leaving Li Fu's house.

Yan Lide could stay here as long as the project on the farm took, but Lu Deming would go back with Li Chengqian and others when they returned to the palace.

I don't know if I will have this opportunity to come to Li Fu's house again in the future.

After dinner, Li Tai secretly looked for Xiao Tao and wanted the two books.

"Your Highness, reading at night is bad for your eyes. My husband said that the three little princes have worked so hard during the day, so they should have a good rest at night. No matter how important it is, they can wait until tomorrow." Xiao Tao said patiently: "People's energy is limited. If the little princes use up tomorrow's energy today, what will happen tomorrow?"

Under Xiao Tao's persuasion, Li Tai gave up.

They returned to the yard together and went back to their own rooms.

After Li Chengqian and Li Tai returned to the room, they did not lie down to sleep immediately.

Shuangxi opened the window, and the wind at night was a little cooler, which made the room much cooler.

There were mosquito-repellent herbs everywhere in the room, which also prevented the room from being invaded by mosquitoes after opening the window.

Li Chengqian sat in front of the desk.

"Brother, what are you doing?" Li Tai also came to sit opposite him.

"I'm thinking about what Uncle Wang said today." Li Chengqian said, "I want to write them down."

"Then I'll grind ink for you." Li Tai said with a smile.

Seeing this, Shuangxi added another candlestick to the desk.

The two children sat at the desk, one grinding ink and the other recalling. After a while, the ink was ready, and Li Chengqian picked up the pen and dipped it in ink and began to write.

"Well? This paper."

As soon as he put pen to paper, Li Chengqian noticed that the paper on the desk was different from the one he used in the palace.

"Qingque, look." Li Chengqian picked up a piece of cut paper and handed it to Li Tai.

Li Tai took it and carefully felt it twice.

"It's different from the hard paper we use. It's thinner and softer." Li Tai said, "Uncle Wang's house has a lot of novel things."

Li Tai couldn't help but sigh.

"Well, ask Uncle Wang for some when I go back." Li Chengqian said with a smile.

After that, he continued to write down what Li Fu said to them during the day.

In his opinion, good advice should be recorded and studied at all times.

It doesn't matter if you only have a partial understanding now, you will understand it thoroughly after a long time.

"Brother, in the evening, Uncle Wang asked us to find the record about waterwheel in the book, and I found it. "Li Tai said: "I originally wanted to study it tonight, but Xiaotao didn't give me the book."

"Xiaotao's words make sense. It's so late, so don't read the book." Li Chengqian smiled.

"But it doesn't matter, big brother, I said, you write it down for me." Li Tai smiled confidently: "Zi Gong traveled south and passed Hanyin on the way back..."

Li Chengqian was stunned, and then quickly picked up the pen and dipped it in ink, recording the content that Li Tai recited on a new blank paper.

"Carve wood into a machine, heavy at the back and light at the front, pump water like pumping, and count like pouring soup."

"You have memorized it all." Li Chengqian looked at his brother in surprise.

"I only memorized this short paragraph, but apart from these, there is nothing else." Li Tai said: "It's just a few words."

"That's also amazing. "Li Chengqian praised: "Fourth brother, you are really talented in studying."

Li Tai was a little shy when he heard Li Chengqian praising him like this.

"Big brother is also very good." Li Tai looked at Li Chengqian seriously: "I am just a little better at studying, but big brother is also very good at other things."

"I am older than you, and I will learn it when you are old. "Li Chengqian said.

While talking, he had sorted out the things he had just recorded.

Li Chengqian was studying what Li Fu had said, and Li Tai was studying the content he had memorized during the day.

The waterwheels used by the people today should not be the waterwheels recorded in the books he had seen, but were improved by later generations.

Uncle Wang also said that there is still room for improvement in the current waterwheels, but how to improve them?

It would be great if there was a structural diagram of the current waterwheels.

At a young age, Li Tai could not study the improvement of the waterwheel from the small paragraph in front of him.

Even in his mind, he only knew that the waterwheel was made of wood and was round. If he thought about it carefully, he could not remember other details.

He wanted to see the waterwheel with his own eyes.

Tomorrow morning, if he had nothing to do, he would like to go to the bank of the Jing River to take a look.
