"This is a medicine, 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 if you take a concubine."

Li Zheng also took over the medicine given to him by Li Xiaogong, "That's actually me..."

"No need to say more, hurry up." Li Xiaogong patted Li Zheng on the shoulder, "You are the prince consort, you married Princess Changle. How many people in Chang'an are watching you."

Li Zheng smiled bitterly.

"I should go back too. I hope you and Your Highness can have a child soon. How many people in Chang'an are looking forward to it?" Li Xiaogong said earnestly.

He had no choice but to send Li Xiaogong away.

Li Zheng stood at the door of his house and thought to himself that Li Lizhi was only sixteen years old.

People in Chang'an are waiting for themselves to be beasts?

He took out the powder that Li Xiaogong gave him, and carefully smelled it with a very strange smell of mold.

I don't know what's in this medicine powder.

Li Zheng fell down casually, and he didn't know what was in these medicine powders.

What if someone is stupid?

The tastes of the ancients were somewhat unique.

Who knows what is in this medicine powder?

What to do if something goes wrong with the food?

Li Lizhi walked out of the house and asked, "Why is the emperor coming?"

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

Li Li looked suspiciously, "Do you have any instructions?"

"Let me hurry up and make a child."

“…”

After a while of silence, Li Lizhi said: "Mingda is still lazy in bed, and she has become more and more sleepy recently."

After saying that, Li Lizhi returned home with a blushing face.

Li Zheng took out some drawings from his room, walked out of the house, and headed towards the entrance of the village. He saw Li Ji and Li Daxiong busy in the field from afar.

When I returned to my original home, my home was still a little messy.

After cleaning up the house, Li Daxiong can eat after finishing his work in the fields.

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

Listening to his aunt's joking words, Li Zheng said dryly: "I'll make my aunt laugh."

The old village chief said: "There is hope for the days in the village. You must have a backpack sooner."

The aunt joked again: "The princess has only been married for so long. No matter how long it is, she will have to wait until next year. How can it be so fast?"

The old village smiled and said, "That's right."

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

Li Zheng avoided his eyes, and the more he talked about this topic, the more he felt something was wrong.

"I'll go to the blacksmith shop to check it out." After casually finding an excuse, Li Zheng left the scene.

The aunt looked at Li Zheng's back and said, "Village Chief, how did Zhenger hide and dodge?"

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 idle recently and don’t have much work to do. At most, they just help the villagers create some farm tools.

Li Zheng handed the drawing to Tieda, "Look, can this thing be created?"

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

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

Tie Da didn't feel anything about the printing speed that Li Zheng said was thirty times.

But since Li Zheng said that, Tie Da nodded and said, "It should not be difficult to do, you can try it."

Li Zheng looked at the furnishings of the blacksmith shop and said, "Have you adapted to living in Jingyang recently?"

Tie Da laughed a little honestly, "The people in the village are very nice to us, and now the child is born."

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

Tieda looked at the drawings and nodded, "Don't worry about Chang'an."

Leaving the blacksmith shop, Li Zheng came to the academy again.

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

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

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

Looking at the drawings Yan Liben was drawing, it seemed that these drawings had been invalidated a lot.

"What is Yan Dajiang drawing?"

Yan Liben explained: "Your tricycle gives me direction. I wonder if I can make a carriage similar to a tricycle that does not require animals to pull."

Li Zheng looked at Yan Liben's strange drawing.

Yan Liben said again: "This is my idea. This carriage is ridden with four people."

Li Zheng observed and said, "Da Jian Yan, it is better than a beast to ride four people. And is hiring four people more expensive than buying a horse?"

Yan Liben thought, "But one person obviously couldn't ride a carriage."

Li Zheng sighed, "Master Yan, water can carry boats, right?"

Yan Liben nodded, "You can also overturn the boat."

"I don't mean that." Li Zheng explained

"What does that mean?"

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

Yan Liben thought about Li Zheng's words, "I seem to understand a little."

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

Yan Liben fell into deep thought and thought about these words.

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

Spread the drawings in front of Yan Liben, Yan Liben looked at them and said, "What is this?"

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

Yan Liben looked at the transmission device, "I'm trying to do it."

He handed the drawings to Yan Liben and Li Zheng left the academy.

I came to the Jingyang River and looked at the current water of the Jingyang River.

I took out another drawing, which was somewhat similar to the hydropower stations of later generations.

To use water storage to provide power, there is enough hydraulic power to push the machine.

Similar to a reservoir in later generations.

Since the Zhengguo Canal was built, the water system in Guanzhong has also developed much more.

However, in the autumn and winter periods, the water system in Jingyang was worse.

The water power of Jingyang River is not very high now.

A dam that can store water needs to be built.

Looking at the river channel more than 500 meters wide, flowing from Linjing Village to Gaozhuang in the southeast.

The Jingyang River is 77 kilometers in total, and the river surface of Jingyang Village is about 300 meters wide.

Building a reservoir is a very large project.

With today's geographical environment, it is not easy to build a reservoir.

Xu Jingzong walked and said, "Chang'an Order, I have been silently vomited to Chang'an."

Li Zheng nodded, "I understand."
