Who is the person behind this? Li Shimin wants to find out.

The prince has been following His Majesty. He doesn't know what His Majesty is thinking at this moment, so he can only walk quietly behind.

When the children arrived at their new home in the mountains, they went to play with the little bear. It was very hot during the day, but at night they became more lively.

Walking to the edge of Huaqing Pool, Li Shimin saw the windmill that the children were talking about.

The waterwheel rotates slowly, but the windmill rotates very fast, and the wind blowing is not strong, but it is not a pleasure in this hot summer.

He can actually live a more leisurely life than me.

"It doesn't make sense, how does this thing spin!"

A loud shout interrupted the leisurely elegance of the moment.

Zhang Yang was enjoying Xiao Wu's back tapping. Her little hands were not very strong and she kept beating with the help of a small wooden hammer.

After taking a look at Tian Khan with an angry look on his face, Zhang Yang said to her: "Okay, I will do it myself."

"Yeah." Xiao Wu put down the wooden hammer and turned to leave.

"Your Majesty, this is driven by magnetic force. There are two compasses at the front and back. The magnets are different in size and quantity. They can naturally drive the windmill to rotate. It is not a profound knowledge."

Li Shimin stared at the two compasses behind the spinning wheel, "Is this what you asked Yan Liben to cast?"

Zhang Yang nodded, "It's pretty much the same, that's the principle."

"Lonet? So as long as there is a magnet, it can keep turning?"

"No, no, the magnetic force is also lossy. Today it rotates fast, but in two days it will slow down or even stop. Just remove it and replace it with the magnet."

Seeing that His Majesty kept staring at it, Zhang Yang smiled and said: "Your Majesty, even if you read it for ten years, you won't be able to understand it just by looking at it. I have a relevant professional book here, which can help you understand the mystery."

While talking, he handed over the book.

Taking the scroll with one hand, Li Shimin looked at the content on the page carefully. With the light of the oil lamp, the Tian Khan's eyes were darkened and he couldn't understand what the picture was.

But in front of Zhang Yang, Li Shimin couldn't look stupid, so he could only nod his head pretending to understand.

"Well, in that case, if I take this book back and go back, can I cast it?"

"That's natural. If Your Majesty can understand the reason, it will be easy to cast it."

Li Shimin put the booklet away and said, "If you had created this thing earlier, I wouldn't have to endure the heat in Chang'an City."

Zhang Yang grinned and said, "Your Majesty, you are just joking. I just came across such a wonderful idea by chance and practiced it before I came up with this thing. I am not hiding it and not showing it out, but learning is a step-by-step process."

This trip was not in vain, so I decided to give this booklet to Yan Liben and have him cast it by hand.

Zhang Yang added: "Actually, this pamphlet is just one of the articles in the next science book. Lishan wants to establish its own sect and school, and Yue'er is the leader. Since we want to open a sect and establish a sect, we need to have our own school."

knowledge system.”

After taking a sip of tea, Zhang Yang sighed: "But this matter is not easy. It may take a lifetime, or it may require several generations of hard work over many years. Science is vast and goes deep into the ocean, and there is no end to learning."

"It seems you have great ambitions."

"This is my wife's goal, I just help her achieve it."

"Yue'er's goal is your goal. What difference does it make between you and your husband?"

Zhang Yang frowned and looked at the lights swaying in the wind, "There are many difficulties and dangers. Even if you are on the sword and in the sea of ​​fire, you must persevere. You must always leave your own footprints in the times. You can also be regarded as a comforting teacher. I must let my

My fellow disciples and those in my hometown know that I did not waste my time in Datang."

Standing up slowly, Zhang Yang told Li Shimin the grand wish in his heart.

"What I have learned is firm materialism. People in my hometown have this persistence. It has long been integrated into my bones and blood. It cannot be erased or eliminated. It is the deepest mark in my memory. I...

"

"It's getting late, I'm going back to rest."

When you are expressing your ambitions, the atmosphere is already tense, and it is very uncomfortable to be interrupted suddenly.

Zhang Yang said in surprise: "Your Majesty, won't you listen to what I have to say?"

"I'm tired, tired."

"Your Majesty, my next words may be enlightening to you."

"I want to go back to the palace. I have to deal with government affairs these days and I will probably not come to the mountain."

The Emperor was quick on his feet, smiling and even cheerful.

Zhang Yang sat down beside Huaqing Pool in despair, looking at the moonlight in the pool, "Your father is so rude."

Li Yue was packing the children's bedding when her husband said this and she was stunned for a long time.

Zhang Yang said again: "How can you not listen to what others have to say?"

Xiao Sizi whispered: "Sister Huang, why is my brother-in-law mumbling to himself?"

Li Yue spread out the quilt and put down her hair in a bun, letting her yellowish hair spread out. "Your brother-in-law has a lot of worries and a lot of things to do. He is like this sometimes."

Xiao Wu and Xu Hui also helped tidy up the bedding, "Master, this happens often. It has been like this for a long time. It might be fine tomorrow morning. Your Highness, there is no need to worry."

Xiao Sizi looked in front of the door for a while, then lay down on the quilt and said, "Sister Huang, I want to eat jelly tomorrow."

The princesses were lying on the big bunk, which was the girls' room.

Adjacent is the boys' room, where there are only three princes, Li Zhi, Li Fu and Li Ming.

Eight sisters and three brothers.

In fact, the father has other children, some have grown up, some are raised by his mother and concubines, and some have their own residences in Chang'an City.

When Li Fu and Li Ming grow up, there will be arrangements for them in the future. Their father may send them into the army, or he may let them go to their respective fiefdoms.

Li Yue closed the door for the children and stood next to her husband, "Are the stars in the pool so beautiful?"

As she spoke, she looked back at her daughter. Xiao Qingqing was holding a brush in one hand. Zhang Qingqing was her name, and she couldn't write it well.

In the end, she gave up and simply sat on the back of the bear and stared at Huaqing Pool in a daze like her father.

"The prince will go to the fiefdom when he reaches adulthood. I heard from my aunt that someone in the palace recently mentioned this matter. Qingque has already reached adulthood."

Li Tai was trained by himself. If he went to a fiefdom, wouldn't all the business methods he taught him be wasted?

Zhang Yang raised his head and looked at the vast starry sky, "The starry sky here is very beautiful. I can't get tired of it. It's more beautiful than the starry sky in my hometown."

"We were talking about Qingque, why did my husband talk about the starry sky again?"

"His Royal Highness the King of Wei has not yet fulfilled his ambition, so he would be unwilling to go to the fiefdom like this. The compilation of Kuo Di Zhi has not been completed, and the construction of Lishan has not been completed, so he cannot go to the fiefdom yet."

"It seems that the mother also expressed in her words that she did not want the children to leave Chang'an City."

No matter how ruthless the Tian Khan is, no matter how wrong the way he teaches his children, there is still a queen.

God is so ruthless, and the queen cares about her children, especially her legitimate sons and daughters, who are all her own flesh and blood.

If the Queen's body can remain healthy, perhaps the overt and covert fights between these children can be subsided.

Zhang Yang put his arms around his wife's shoulders and said, "Brother-in-law, I will have to work harder from now on."

"It sounds like Qingque and the others are ignorant."

"Who knows, they are all my younger brothers and sisters. I will have to worry more about it then. Aren't we just going to settle the issue of Li Tai going to the fiefdom?"

Li Yue smiled and said: "Then there will be Mr. Lao Fu."

Recently, due to the scorching heat, the Lishan factory only operates in the morning and evening and has been shut down since noon. Normally, the Lishan factory operates for three to four hours.

But now the Lishan factory only works for one to two hours a day.

The blacksmith shop immediately stopped working, except for the necessary maintenance of farm tools when it occasionally resumed work. Usually, the stove was not even fired.

This made Li Shimin very dissatisfied. He looked at the hematite and coal piled up into a hill and said to Shangguan Yi: "How long will it take for the blacksmith workshop to resume normal operation?"

"Work will start after the hot summer."

The person who runs the village is Shangguan Yi. This guy worked in Hongwen Hall many years ago and is also a diligent person.

After the riots in the former Sui Dynasty, the family fell into decline.

But he could be regarded as a famous official, but the young man did not want to succumb to others, so he came to Chang'an City alone, hoping to find an official career.

The blind Hongwen Museum didn't recommend it to me earlier, so how could it fall into Zhang Yang's hands?

Today, I made an appointment with His Majesty and the Prince, as well as the King of Wei and Li Xiaogong to go fishing together. Zhang Yang was sitting at the entrance of the village wearing a hat to protect the sun and holding a fishing rod.

The Foreign Affairs Council still rejected the Uighurs' apology. This incident caused the impeachment of many officials in the court. The emperor was vacationing in the summer, and even if they were dissatisfied, things had already come to this.

Zhongshu Province did not express any opinions on this rejection of the Uighurs' apology, and even tacitly approved of it.

When the officials delivered the impeachment memorial, Zhongshu Sheng responded immediately and sent people to transport it to Lishan.

"This matter must have been done by Duke Zhao."

Li Tai, who was also carrying a fishing rod, asked puzzledly: "How do you think it was done by Zhao Guogong?"

Zhang Yang nodded and said: "Because he is definitely the most active and obligated to cause trouble for the Foreign Affairs Council."

Li Tai was silent for a long time and murmured: "But some people say it was arranged by Mr. Zheng."
