People in Datang have been expelled from school

Chapter 532

"This is medicine, and it should work," Li Zheng said.

After putting away the pills, Li Xiaogong coughed twice and said seriously: "You, you still have to hurry up, and you should also hurry up about taking concubines."

Li Zheng also put away the medicine that Li Xiaogong gave him, "That's actually me..."

"Needless to say, hurry up." Li Xiaogong patted Li Zheng's shoulder, "You are a son-in-law, married to Princess Changle, how many people in Chang'an are looking at you."

Li Zheng smiled wryly.

"It's time for the old man to go back. I hope you and Her Royal Highness can have a child soon. How many people in Chang'an are looking forward to it." Li Xiaogong said earnestly.

Reluctantly, Li Xiaogong was sent away.

Standing at the door of his house, Li Zheng thought to himself that Li Lizhi was only 16 years old.

Everyone in Chang'an is waiting to become a beast?
Taking out the medicinal powder that Li Xiaogong gave him, he carefully smelled it, and there was a very strange musty smell.

I don't know what's in the powder.

Li Zheng poured it down casually, and he didn't know what was in the powder.

What if people are stupid?
The taste of the ancients is somewhat unique.

Who knows what's in the powder.

What should I do if something goes wrong?
Li Lizhi walked out of the house and asked, "Why is Uncle Huang here?"

Li Zheng looked at Li Xiaogong's back and said, "Just left again."

Li Lizhi looked suspiciously, "Is there something to ask?"

"Let me hurry up and make a baby."

"..."

After being speechless for a while, Li Lizhi said: "Mingda is still on the lazy bed, and he has become more and more sleepy lately."

After speaking, Li Lizhi blushed and returned home.

Li Zheng took out some blueprints from his room, walked out of the house, and walked all the way to the entrance of the village. He saw Li Ji and Li Daxiong busy in the field from a distance.

When I returned to my original home, it was still a bit chaotic.

Clean up the house and cook a few more dishes. Li Daxiong can eat it when he comes back from working in the field.

The old village chief and aunt who passed by came over with a smile and said, "Zheng'er, he is also a man now."

Listening to his aunt's joking words, Li Zheng said with a dry smile: "I made my aunt laugh."

The old village head said: "There is hope for life in the village, Zheng'er, you also want to have a queen sooner."

The aunt joked again: "How long has it been since the princess got married, and no matter how you say it, she will have to wait until next year, how can it be so fast."

The old village stroked his beard with a smile and said, "That's right."

The aunt said: "Zheng'er, you have to work harder!"

Li Zheng averted his eyes, the more he talked about this kind of topic, the more he felt something was wrong.

"I'll go to the blacksmith's shop." Li Zheng made an excuse and left the scene.

The aunt looked at Li Zheng's back and said, "Village Chief, why do you think Zheng'er is evasive?"

The village chief sighed and said, "Zheng'er is a kind child."

Li Zheng came to the blacksmith shop with the drawings.

The three brothers of the Tie family have been relatively free recently, and they don't have much work to do. At most, they just help the villagers make some farm tools.

Li Zheng handed the blueprint to Tie Da, "Look, can this thing be built?"

Tie Da looked at the drawing and asked, "What is this?"

"This is called a rotary machine, which is used for printing. With this thing, our printing speed can be nearly thirty times faster in the future."

Tie Da didn't feel much about Li Zheng's [-] times printing speed.

But since Li Zheng said it, Tie Da nodded and said: "It shouldn't be difficult to do, you can try it."

Li Zheng looked at the current furnishings of the blacksmith shop and said, "Is it okay to live in Jingyang recently?"

Tie laughed a little honestly, "The people in the village are very kind to our family, and now the child is born."

Li Zheng pointed to the blueprint and said: "The manufacturing requirements of this rotary machine are a bit high, especially in terms of size. If you are not sure, you can ask the children in the academy for help."

Tie Da looked at the blueprint and nodded, "Chang'an Ling is at ease."

After leaving the blacksmith shop, Li Zheng came to the academy again.

Yan Liben has been in the academy these days and rarely goes to court.

When we came to the academy, a group of children were listening to Li Chunfeng's lecture.

Li Zheng came to Yan Liben's room. At this moment, Yan Liben was drawing various blueprints. When he saw Li Zheng coming, he said, "Li Zheng, I happen to have something to ask you."

Looking at the drawings that Yan Liben was drawing, it seemed that many of these drawings had been discarded.

"What is Master Yan painting?"

Yan Liben explained: "Your tricycle gave me directions, and I wondered if I could make a horse-drawn carriage similar to the tricycle without being pulled by animals."

Li Zheng looked at Yan Liben's weird drawing.

Yan Liben said again: "My idea is this, this carriage needs four people to ride together."

Li Zheng observed and said: "Dare to be Master Yan, four people riding a horse is not as good as cattle, and is it more expensive to hire four people than to buy a horse?"

Yan Liben pondered, "But obviously a person can't ride a carriage."

Li Zheng sighed: "Master Yan, water can carry a boat, right?"

Yan Liben nodded, "It can also capsize the boat."

"That's not what I meant." Li Zheng explained
"what does that mean?"

"Water can push a boat, and wind can blow leaves."

Yan Liben thought about Li Zheng's words, "The old man seems to understand a little bit."

Li Zheng continued: "The transmission of the tricycle comes from human power, what if it is not human power?"

Yan Liben fell into deep thought, thinking about these words.

Li Zheng took out a blueprint and said, "Actually, I came this time to ask Master Yan to make something."

Spreading out the drawing in front of Yan Liben, Yan Liben looked at it carefully and said, "What is this?"

"This is also a transmission, but this one is a water-driven transmission."

Yan Liben looked at the transmission device, "I'll try to do it, old man."

After handing over the drawings to Yan Liben, Li Zheng left the academy.

Came to the Jingyang River, looking at the current Jingyang River.

He took out another blueprint, which is somewhat similar to the hydroelectric power station of later generations.

Using water storage to provide power requires sufficient water power to drive the machine.

Similar to a reservoir for later generations.

Since the Zhengguo Canal was built, the water system in Guanzhong has also developed a lot.

It's just that in autumn and winter, the water system in Jingyang is bad.

The water power of the Jingyang River is not very strong now.

A dam that can store water needs to be built.

Looking at the more than 500-meter-wide river, it flows from Linjing Village to Gaozhuang in the southeast.

The Jingyang River is 77 kilometers long, and the river in Jingyang Village is about 300 meters wide today.

Building a reservoir is a very large project.

Coupled with today's geographical environment, it is not an easy task to build a reservoir.

Xu Jingzong came up and said, "Chang'an order, I'm vomiting in Chang'an."

Li Zheng nodded, "I see."

Xu Jingzong said again in a low voice: "But Mou was arrested by people from Dali Temple just after he arrived in Chang'an."
