In mid-September, after half a month of debugging and installation, the keel water truck could finally rotate in the Zhang River.

The car is 10 meters high and supports 24 wooden spokes in the middle, spreading around in a radial state, like a bicycle wheel that has expanded ten times.

There is a scraper and a water bucket at the top of each spoke. When the water bucket that holds water is lifted up step by step, it will naturally tilt, injecting water into the ferry and flowing into the reservoir high on the river bank. If farmers want to irrigate the land, they just need to dig a channel beside the reservoir and lead to their own fields and irrigate it automatically.

Such a worldly invention, Han Yan directly wrote a letter and sent someone to Liu Che, asking him to help submit a memorial to Emperor Jing of Han, asking people to inspect. If he felt that he could, he would promote it all over the world, which could improve irrigation efficiency, increase farmland output, and benefit the country and the people.

Prince's uterus.

In September, the weather in Chang'an is like a steamer, which is so hot that it makes people breathless, but Liu Che's room is cool and refreshing.

There is a bronze ice magazine in the house, four-legged beast, eight dragon ears, and hooked cloud patterns, which is quite exquisite. This thing is equivalent to a modern refrigerator, which emits cold air from time to time. There are also iced sweet springs and frozen fruits inside for use at any time.

Not to mention this, there was a servant who shook the bearings of one person high, and there were seven huge fans connected to the shaft. They were created by skilled craftsmen in Chang'an. They were shivering all over the hall. But they were pitiful to the servant, sweating all over the head...

"Report to the letter from His Highness the Crown Prince, Han Yan." A guard in front of the door reported, his armor was not airtight, and the sweat between his eyebrows was flowing down.

Liu Che was eating cherries bored. On this hot day, even the emperor went to Ganquan Palace to escape the summer heat. The court was over and everyone stayed at home.

But it's so boring at home... So Liu Che often misses his sworn brother. If Han Yan was there, he would always think of ways to have fun, and he wouldn't be so lonely.

Upon hearing the guard's report, Liu Che quickly got up and shouted hurriedly: "Come on."

As he said that, he grabbed a handful of cherries from the bronze ice arc and gave them to the guards, "Take it to eat."

"Thank you, Your Highness," the guards trembled with excitement, knelt down and kowtowed to bow before leaving.

After carefully reading Han Yan's calligraphy that was so ugly that it was so ugly that Liu Che's smile gradually filled up.

"Oh, you little rock, you won't be at ease when you go home. With this keel waterwheel, the harvest of the people on both sides of the river will increase. You can afford taxes and be healthy. I will go to report to my father."

...

Since the death of Liang Wang Liu Wu, King Chengyang Gong, and King Runan died one after another. The brothers passed away one by one. Their era has passed, which made Emperor Jing of Han feel sad and his physical condition worse and worse.

He could only stop the mountain memorial, without the physical strength or energy.

However, thinking about this life, Emperor Jing was still very pleased. The great man was thriving under his governance. The number of people who were beaten to prison this year was less than 200. The money in the treasury accumulated tens of millions of dollars, and the ropes that lined the money were decayed and could not be counted. The old corn in the granary was covered with layers of layers, and they all flowed out of the warehouse. They had to accumulate outside the outside, so they rotted and could not be eaten.

Just as he was thinking about his achievements, he saw Liu Che coming in from outside the hall.

"The child bowed to the father."

"Get up." Emperor Jing raised his hand and looked down at his heir. His heart was ups and downs. I remember when I was the crown prince, I was like Che'er bowing to my father, but in a blink of an eye, I was old and a hero was old.

After watching it for more than ten seconds, Liu Che was so heartbroken that Emperor Jing asked, "Is there anything wrong?"

"Reported to the father, Han Yan went home to visit Gong Gaohou and created something called a keel waterwheel that can solve the irrigation problem of 700 acres of land along the river. The farmers' poor harvest was partly due to the lack of watering. He wanted his father to send someone to see it so that the waterwheel could be implemented nationwide."

"Oh?" Emperor Jing raised his eyebrows, a little surprised.

The boy with Hu blood had a deep eyes and was a good archer who rode and archery since he was a child. Unexpectedly, he would not do his job properly and not read the books of sages, but went home to invent and create. If the people in the world learn from you and like curious skills, then who would still farm and what are the people eating?

I heard that Han Yan was creating, Emperor Jing’s first reaction was that he didn’t like it. But what he invented was something that was conducive to agricultural production and could increase grain production. Do you use it or not?

After thinking for a while, Emperor Jing looked at the ardent earnestness in Liu Che's eyes, knowing that the child was also pleaded for the people. He sighed and was unwilling to give him a face, saying, "Since Han Yan has this ability and you will submit a memorial, then I will follow his wishes and ask your teacher Wei Wan to go to Gonggao Hou Kingdom to take a look and consider the students he taught. But..."

Emperor Jing had a erect face, sat upright and stood upright, with his waist straight.

"Cheer, you must be clear that governing the world's food is the first priority. Whether the people are rich or not, whether the people can eat enough depends on the farming. If there are many people who are idle and immersed in strange tricks and tricks, it will affect agriculture and shake the foundation of the country. Furthermore, he is a descendant of the princes and the descendants of the country, but does not serve as a craftsman's work, and does not wait for a good house. If you ask Wei Wan to tell Han Yan, the unhealthy trends should not rise. Even if he creates a dragon bone water wheel, which is beneficial to the people, I will not praise him, and it can only be considered a merit or demerit."

"This..." The young Liu Che lowered his head deeply, afraid that Emperor Jing would see his expression. As the crown prince of the Han Dynasty, keeping in agreement with the emperor's thoughts was the most important reason why you can ascend the throne. Even if you don't agree in your heart, you quickly responded: "Child is respectful to the teachings of the father."

Emperor Jing was a little worried and reminded again: "Governing the country is reliable and upright. Han Yan created a keel water truck and was just his temporary interest. This cannot be eaten as a food, and you must not learn from him."

"I understand, let Teacher Wei Wan scold Han Yan." Liu Che's speech was powerful, and he agreed with Emperor Jing's words like a gold-breaking stone.

"A child can be taught." Emperor Jing of Han smiled, satisfied with his heir, and ordered: "Go and see your grandmother, she misses you very much these days."

"Here." Liu Che responded, and after saluting, he left the palace.

When I went out, I lamented. I originally wanted to ask Han Yan for me, and I also wanted to show off my ability to employ people to my father. Seeing how talented my sworn brother is, I didn't expect that he would be hit by the head, but he was not recognized, but was scolded instead...

Young people like novel things, and Liu Che is no exception. He is very hard in the palace, and being a crown prince is even harder. He has to behave properly every day and dare not do anything out of order. It is like a little monkey locked in an iron cage, looking at the world with curiosity. If someone throws something into your cage, he will never be reluctant to throw it away if he is not tired of playing.

Growing up in the palace, Liu Che was very scheming and had a strong rebellious attitude towards reparations. Now Emperor Jing is still in power, I have no choice but to wait for me to become the emperor...
