The city walls of the Gonggaohou Kingdom are not high, but they are also mottled ancient walls. They are destroyed by time and the vicissitudes of life. The occasionally visible moss under the city tells the traces of the passing of time.

The mansion of Gonggao was unable to be opened, so Han Yan had to take a group of people out of the city and set up a shed in the shade under the city walls, allowing the six strong men to use materials locally and cut down elm wood to bring them back.

Han Yan told Carpenter Li about the keel water truck he wanted to build... In modern terms, it is called overturning. He is ready to install it on the bank of the Zhang River to solve the problem of farmland irrigation among the people of the Gonggaohou Kingdom.

The fallout first appeared in the Eastern Han Dynasty. In the Book of Later Han, Bi Lan recorded that it was a fallout, and Ma Jun of the Three Kingdoms period improved it. This thing should have appeared in the late Han regime in the east.

Han Yan had never read the history books and could not remember them even after reading them, but it is certain that the Han Dynasty did not fail.

Carpenter Kasai showed great enthusiasm for this kind of automatic water storage and irrigation tool, and his eyes were shining...

While Carpenter Li made a rollover, a large amount of wood chips and bark remained. Han Yan did not let them be thrown away. Instead, he placed them on an open space like a treasure, and asked the coachman to help him go to the city to buy hemp, rags, old fishing nets and other things.

Half a month passed in a blink of an eye.

Mid July.

Mountains, rivers, beliefs, and the great Han Dynasty were particularly high.

Life, youth, and everything are quite vigorous.

Perhaps it was the arrogant spirit of the head of the Hei Family in Anlu County who was sitting on the emperor's frame that stimulated Emperor Jing of Han, so he issued an edict.

"Officials are the example of the people, and their clothes and carriages should be commensurate with their positions. It is now stipulated that if the clothes and entourages of chariots and entourages are not commensurate with their identities, they should be reported to their competent departments, and the lieutenant in charge of the title and the left and right internal historians must investigate those who do not comply with the official body."

An edict made the world's powerful people restrain themselves. Anyone who dared to overestimate the system was a master with title. Ordinary people would never dare to play like this, nor did they have the financial resources to play with the emperor's majesty.

Han Tuidang has always been paying attention to Han Yan. He is too lazy to care about this evil grandson's early departure and late return.

If Han Yan went to the street to tease a good woman, Han Tuidang would probably come forward to save him, and then take him home to break his legs, so that this evil grandson would be paralyzed in bed for the rest of his life, the reason was... he would no longer have to watch you wander in front of me. He was upset.

Gonggao Hou Mansion.

The carpenter does rough work, and Xier only goes out of the city to help Han Yan deliver food every day, and stays in the mansion the rest of the time.

She didn't think much about the Marquis' summoning.

Han Tui was exhausted and came back a few days ago. He wanted to go to Chang'an to contact Zhou Yafu's old subordinates to plead with the emperor, but on the way, he was persuaded by people sent by his family to come back.

Compared to Han Yan next to Liu Che, the Emperor of Gonggaohou Kingdom was far away. Even if Han Tuidang was stunned, he would not think that he was more informed than the evil grandson.

Han Yan's words explained the inside story thoroughly. His Majesty wants to deal with Zhou Yafu and pave the way for the crown prince. Not to mention you, a Gong Gaohou, even if you have another hundred, you will be useless. This is a major event about the safety of the country. No matter how deep your brothers are, they are not as important as the Han Dynasty.

Thinking of this, Han Tuidang sighed softly and looked at Xier in the hall and asked, "When I came back, I saw Han Yan building a shed outside the city, and with a group of people who were not doing their jobs and started a carpenter's business. What do he want to do?"

"Crown Prince Yan said he wanted to cut wood into wheels and build a super big wheel to put it in the river." He said with his hands spread out and gestured.

“What’s the use of this wheel?”

"Um..." Xier thought about it before answering: "I heard from the prince that this wheel can solve the problem of irrigation in our Gonggao Marquis."

"Oh." Han Tuidang picked up the tea cup, sucked the tea leaves with the cover, took a sip and moistened his throat, and smiled indifferently, thinking that if you have this ability, I will look up to you.

"I also heard that he asked someone to collect things in the city, and he also used it to make wheels?"

"This prince didn't say it, and I didn't know it either. But when I was delivering food to the prince, I saw that he soaked the things he received, as well as wood chips and bark in a large jar to make it swell. Then he chopped it with an axe and mashed it, washed it many times with water, then steamed it with water, and then washed it several times. It was so troublesome."

Xier told the past half month of experience and was confused and didn't know what Han Yan was going to do, but judging from his posture and seriousness in his eyes, it seemed like he was going to do something earth-shaking.

"Let him go, something that is not a weather-free thing, not by the crown prince, to establish a good relationship with the crown prince of the Han Dynasty, but instead live poorly outside the city as a vulgar craftsman, hum." Han Tui was so angry that he snorted coldly.

But after humming, he suddenly felt that something was wrong. He didn't go out for nothing. He heard about Han Yan on the road. Although some reputation was insignificant, it also showed that this evil grandson was not a fool...

After pondering for a while, Han Tuidang decided to go out of the city to see it in person and find out.

"Can he really make water grow in the fields?"

With this idea, Lao Han took a carriage out of the city.

It is already the hot summer season in mid-July, and there is no cloud in the sky. Occasionally, a gust of wind is wrapped with heat waves, blowing the rolling leaves and rushing to the city, and circling there, until the hot wind is weak, it will stop.

Han Yan finally took off his gorgeous brocade robe, couldn't stand the heat, so he put on a thin sweatshirt and did an experiment tirelessly by the big tank.

He has boiled the bark, hemp and other things into fine fibers. Then he has to blend the fine fibers into a suitable slurry with water, and then use a leaking paper mold to pick up the pulp. After dehydration and drying, it will be paper. This process has a long way to go.

At the gate of the city, Han Tuidang was stunned for a moment when he saw him so serious. Looking at the giant wheel that had already had a prototype and the dragon bone water wheels that looked like long dragons, he suddenly felt a little joy in his heart... He might not be sure that he would lose, maybe he could really solve the problem of irrigation in the Gonggao Marquis Kingdom.

No, it is not just the Gonggao Marquis Kingdom, but as long as this giant ship is effective, farmers along the river can benefit. This is a major project that benefits the people of the world.

"Grandpa." Seeing Han Tui standing at the gate of the city, he didn't get closer to see. Due to politeness, Han Yan stood up and said hello.

"Can this thing work?" Han Tuidang stared at the wooden giant wheel nearly ten meters wide. Although it was just a contour, it was also shocking enough.

"If nothing unexpected happens, it will definitely be possible." Han Yan said, wiping the sweat on his forehead with a hand towel.

Carpenter and servants rushed over and saluted Han Tuo, very respectful.

"Everyone do it. Yanzi and I have a few words to say." Han Tuodang didn't like these people very much, so he waved his hand to let them retreat. With a yearning for the past in his eyes, he slowly asked Han Yan: "Is Tiaohou really helpless?"

"The great achievements shocked the Lord, and his character was arrogant and arrogant. Your Majesty didn't take him. How could the Crown Prince save the world after he ascended the throne?" Shaking his head, then scooped up a scoop of water from the water tank and poured it into a basin, increasing the moisture of the fine fiber slurry, because the one just now was too thick and water could not be soaked from the paper mold.

Han Tuidang: "When are you planning to go back to Chang'an?"

"It's not clear that there are many noble relatives in Chang'an. Although Liu Che is protecting me, I don't have any foundation and rely on his favor. When I have a foundation and can be chopped off and fed to the dog without being chopped off by someone to feed it to the dog, I will go back."

"..." Han Tui was speechless. Even the princes, who had to keep going to Chang'an, had to keep going. When you had a foundation, the sun would probably come out from the west. "I think it would be better for you to stay by the crown prince."

"You don't understand."

Han Yan didn't want to explain anymore, but just covered his head and did an experiment. There was a faint hope in his heart fermenting...

Han Tuo no longer advised him because he couldn't understand Han Yan anymore, and because there were soldiers galloping in the distance, as if there were a big matter of urgent need.

"Report..."

The soldiers' urgent horns seemed shrill and echoed outside the city gate.

"The Huns invaded Yanmen, killed them to Wuquan, then went straight to Shangjun, took the Yuan horse and left. More than 2,000 soldiers of our Han soldiers killed more than 2,000 people, and blood flowed into a river!"

"What?" Han Tuidang glared in his eyes, his blood surging, and he gritted his teeth.
