Prince of Tang Dynasty

After Li Yu told Empress Changsun and Li Shimin about the bank and bank notes, he didn't bother with it anymore.After he recovered from the cold and cough, he returned to Zhuangzi impatiently.

Originally, Empress Changsun and Li Shimin did not agree with him returning to Zhuangzi, because he was good due to the cold, and they were worried about him, but Li Yu disliked the fact that the palace was too hot, and he couldn't use ice, and he would die of heat if he stayed in the palace.Besides, Zhuangzi is cooler than the palace, so he will go to Zhuangzi to spend the summer.

Zhuangzi is much cooler than the palace, and the most important thing is that there are still many things waiting for him to do in Zhuangzi.

The veterans have been to Zhuangzi for more than [-] days, and they don't know what to do with Zhuangzi.

Although General Song and Zhou Yi were watching, Li Yu was still not at ease, so he had to go to Zhuangzi to sit in charge.

At this time, Li Yu and Li Zhi were on their way to Zhuangzi.

"It's so hot." Li Mingda raised his hand and wiped the sweat off his face with his sleeve.

Li Zhi nodded in agreement: "It's so hot, this summer seems to be hotter than last summer."

"I told you to bring some ice and put it on the carriage, but you didn't listen." Compared to Li Zhi and Li Mingda who were sweating profusely, Li Yu looked very refreshed.Perhaps because of his weak body, Li Yu didn't feel that hot.

"Little Yu'er, you can't use ice." Li Mingda had a serious face, and his tone was very stern, "Can you just forget about your cold?"

"I asked you to use ice." Li Yu put his head in his hands and leaned against the wall of the carriage, looking very comfortable. "I'm not hot, so why use ice?" He realized that there was something wrong with his poor health The good thing is that it is not afraid of heat.

Li Mingda and Li Zhi saw that Li Yu's face was not sweating at all, and they cast envious glances at him.

"I'm going to die of heat." Li Mingda pouted and said unhappily, "Why is it so hot?"

Li Yu asked, "Why don't you bring a fan?"

Li Mingda said aggrievedly: "Forgot."

Li Yu: "...Then you have to bear it for a while." As soon as he finished speaking, he thought of an idea, "Ninth brother, didn't you bring the book?"

"I did bring a book, but the book is too thick to be used as a fan." Li Zhi just thought of one thing after another, and looked at Li Yu warily, "Xiao Yu'er, you don't want to tear up the book, do you?"

"What do I tear up the book for, besides the book, do you bring any paper?"

"There are papers." Li Zhi quickly took out a stack of white papers from his schoolbag.

Li Yu took out a sheet from the stack of white paper that Li Zhi took out, and began to fold it upside down.After everything is folded, fold it in half from the middle, and a simple small fan is made.

"Minda here."

"Little fish, what is this?"

"Paper fan." Hearing Li Mingda's question, Li Yu asked a little strangely, "Have you never seen this fan?"

Li Mingda shook his head: "I've never seen you make this kind of fan." After she finished speaking, she fanned herself and laughed happily when she found that she could generate some wind.

Li Yu then folded a paper fan for Li Zhi, "Ninth brother, here you are."

"Thank you, Xiao Yu'er." Li Zhi took the paper fan Li Yu gave him and slowly fanned it.

After hearing what Li Mingda said just now, Li Yu suddenly remembered one thing, that is, he seemed to have never seen a person from Tang Dynasty holding a folding fan.To be precise, he had never seen a Datang person holding a fan.

He had seen A Niang and the others holding fans in their hands in the palace, but they were holding round fans, not folding fans.From this point of view, the folding fan has not yet appeared at this time.

He is going to be a dude in the future, he doesn't have a folding fan in his hand, how can he pretend to be coercive.Folding fans are an indispensable tool for many dudes.

"When I get to Zhuangzi, I'll make a folding fan for you to learn more about." Folding fans are not only loved by playboys, but also by literati and poets.They like to write poems and draw pictures on folding fans.

"Xiao Yu'er, what kind of fan is a folding fan?" Li Mingda asked curiously.

"The folding fan looks like this..." Li Yu picked up a pen and drew the shape of the folding fan on the white paper.

After Li Zhi and Li Mingda saw the folding fan painted by Li Yu, they immediately fell in love with it.

"Little Yu'er, when you get back to the village, you must quickly get out this folding fan."

"Let me tell you, the folding fan is very useful." Li Yu pointed to the fan and said, "You can write poems and songs on this fan, or draw pictures..."

"Little fish, I want it!" Li Mingda liked folding fans even more after hearing what Li Yu said about folding fans.

Li Yu felt that after he got the folding fan out, it would definitely become popular in Chang'an City, so why didn't he open a folding fan shop in advance.

He raised his hand and patted his thigh, and said excitedly: "We can open a folding fan shop, and literati and poets will definitely spend money to buy folding fans."

"That's a good idea."

The three brothers and sisters sat in the carriage and discussed opening a folding fan shop.

At noon, the three brothers and sisters finally arrived at Zhuangzi.

I haven't returned to Zhuangzi for nearly a month, and the whole Zhuangzi has undergone earth-shaking changes.To be precise, the whole Zhuangzi has become a mess.

During this period of time, the veterans were busy plowing the land, plowing all the land near Zhuangzi, so it was a mess.

The veterans pulled up their sleeves and trouser legs, and worked hard to cultivate the land under the scorching sun.Look carefully at their expressions, everyone has a smile on their face, without any impatience or pain.

Li Yu didn't go to disturb the veterans working on the land, but stood aside and watched from a distance.Seeing that the veterans plowed the land too slowly and with great difficulty, they could not plow much land in half a day.

Of course, he didn't dislike the slow work of the veterans, but felt that the tools used to cultivate the land were not good enough.

Li Yu didn't know much about the farming tools of the Tang Dynasty, but he was sure that the farming tools used in the Tang Dynasty were not as useful as those used in later generations.

He called Monday over, "What do they call the thing they use to plow the land?"

"Return to Your Highness, that is Qu Yuanli."

"Quyuanli?" Li Yu knew about Quyuanli. It was mentioned in history books, "Did the Tang Dynasty use this kind of Quyuanli to cultivate land?"

"Yes, Your Highness."

"Is there any extra for Zhuangzi?" Li Yu decided to take a good look at the Quyuanli that Datang is now using to plow the land.

"Yes, but what do you want Qu Yuanli to do, Your Highness, you don't want to plow the land, do you?"

Li Yu gave Zhou Yi a supercilious look, "Of course not, my weak body doesn't have the strength to plow the land." Even if he has strength, he doesn't know how to plow the land, and it's not a contract to support him, "Bring me one and show me .”

He felt that the efficiency of people using this kind of curved shaft plow to plow the land was too slow. The plows used in later generations were pulled by oxen, which would be much more convenient and trouble-free, and more land would be plowed.

"Slave, go get it now."

"Little Yu'er, what do you want Qu Yuanli to do?" Li Zhi asked suspiciously, "Do you think there is something wrong with Qu Yuanli?"

"The work efficiency is too low." Li Yu frowned slightly and said, "Using people to push the plow to plow the land is not only a waste of human energy, but also not much land can be plowed, so I want to improve it." At the grandfather's house in the countryside, he saw a modern plow, and he thought it could be combined and used to improve a new plow to cultivate the land.

"Little Yu'er, if you can improve Quyuanli better, it will benefit the people in the entire Tang Dynasty." Li Zhi felt that Li Yu would definitely be able to improve Quyuanli better.

"I didn't think so far. I just think that the veterans can't plow the land near Zhuangzi well after several months of plowing the land like this."

Li Mingda's small face was flushed red from the sun, his head and face were covered with sweat, the heat was unbearable.

"Brother Jiu, Xiao Yu'er, can we go back to Zhuangzi first, I'm about to die from the sun."

"Okay, let's go back to Zhuangzi first." Li Yu still has a lot of things to ask Zhou Yi.

On Monday, I took a Qu Yuanli to see Li Yu. After seeing it, Li Yu felt that it was too crude and could be improved.However, the matter of improving Quyuanli will be discussed later, and now he wants to know what happened in Zhuangzi during this period.

The author has something to say: update so much first.

Folding fan is a powerful tool for pretense, how can we do without it.
