The slender bamboo silk was flying between his fingers, but Liu Yi's eyes looked at the two children who were fighting together in the martial arts room with interest. At first, the two of them were holding their own wooden knife and wooden spear, but they probably felt that it was not easy to fight, so they threw away their fists and feet and started fighting without any intention of tying up. Liu Yi thought that it was normal for children to fight. As for the cause, it seemed that they were arguing about which fathers of the two families were more powerful and tried to convince the other party, but in the end, they obviously wanted to defeat the other party and let the other party admit their views.

This is the world of children, and there is no reason to say. It seems that no conclusion is given to which Zhang Fei or Guan Yu is more powerful in both the official history and the Romance of the Communist Party of China. However, in terms of reputation, Guan Yu is more famous now and in the future.

"Don't care?" Cui Zhouping threw a nut into his mouth and asked.

"What do you care about? I want to know too." Liu Yi asked back: "That's right, Ma Su has been busy all these days, and his feet are not touching the ground. Are you a little unduly aware of your duties?"

Ma Su has good talent, but the four counties have helped Ma Su, but Cuizhou Ping has even returned to the capital less recently, so there will be no problems, right?

"I was really busy at the beginning, but now I have basically sorted out. Just go back regularly and stamp it. Go back four or five times a month, and it's almost enough." Cui Zhouping said indifferently.

So, is this the reason why you come to have a meal every day?

Liu Yi did not say it directly, but said, "Otherwise, bring your sister-in-law and the others together."

"Not very good." Cui Zhouping nodded thoughtfully and said, "But since Bo Yuan invited me, it's better to obey your orders than to be respectful."

Liu Yi: “…”

He suddenly realized that from when Cui Zhouping's emotional intelligence had decreased, or his skin had become thicker.

Cui Zhouping turned his head and looked at the gradually forming bamboo bird in Liu Yi's hand, making fun of it: "This is not like Bo Yuan's craftsmanship."

The bamboo bird is just a rough outline, which makes people see it as a bird, but it is not as vivid as the carvings that Liu Yi made in the past.

"There is no need to be vivid." Liu Yi did not explain. The bamboo craftsman has made a single skill. He has only figured it out recently. With a pair of skilled hands, he can control it, but his attributes have not yet come out, let alone appear vividly.

"Oh?" Cui Zhouping saw that Liu Yi had tied a knot while he was talking, and the bamboo bird was finished. He asked with a smile: "I'm afraid this thing will break when you touch it, how can I play with it?"

"Who said he was playing with it?" Liu Yi pulled the bamboo bird's mouth and raised his hand. The bamboo bird blew its wings in Cui Zhouping's astonished gaze, and flew upwards, hovering above the heads of the two people. For a moment, it turned out like a real bird, and had not fallen.

"How to do this?" Cui Zhouping said in surprise.

"I have told you about mechanics that there is also a powerful existence in the air. I flap my wings, imitate the movements of birds, and rely on the power of mechanisms within..." Liu Yi said a lot of numbers, and Cui Zhouping could not fully understand the rules after listening for a moment.

But he frowned and said, "If this mechanical bird is enlarged and made of wood, can it be carried to fly to the sky?"

Flying has always been something that humans desire, both in the East and the West.

"You're thinking too much." Liu Yi shook his head and said, "Do you know why I use bamboo silk to make it?"

Looking at the bamboo bird that began to slowly descend after flying for a while, Liu Yi sighed: "Because the bamboo silk is light, if it is replaced with a wooden board, it will not be able to fly. Even so, the internal mechanism dare not do more. If it is enlarged and made with bamboo silk, it is feasible. But let alone carrying people, it is even impossible to get a stone tied up, and the bamboo silk is fragile and not suitable for carrying people."

Liu Yi also thought about flying. If there are enough conditions, he didn’t know what would happen if he made a hot air balloon or glider with the blessing of his attributes. But these thoughts were just thinking about it. Don’t think about hot air balloons for the time being. There are many problems to solve. Gliders are simple, but without any parameters, safety is not guaranteed. Who will be used as a test subject? It is easy to kill people.

"Uncle Bo Yuan, what is that?" Guan Xing and Zhang Bao stopped fighting each other at some point, ran over with a bruised nose and swollen face, looking at the stopping bamboo bird in Liu Yi's hand.

"Do you want it?" Liu Yi looked at the two boys and laughed.

"I want to!" Guan Xing and Zhang Bao have become familiar with Liu Yi during this period. They are not as shy as they were at the beginning. They don't hide their heads at this moment and nodded.

"Remember the multiplication formula I taught you and can write it down, and give it to each person." Liu Yi smiled.

The 99 multiplication table is a cultural course taught by Liu Yi during this period. Although it is not difficult, it is quite practical. In this era, as a general, you need to count the number of people frequently, and this multiplication table is enough.

"Okay!" Guan Xing and Zhang Bao heard this and said in unison. That thing was not difficult for them. Liu Yi had already told them the algorithm.

"Have you finished your new book?" Cui Zhouping looked at Liu Yi and smiled.

"It's not yet, it's just some simple algorithms that will be gradually improved in the future." Liu Yi shook his head. He is now working hard to simplify the translation, summarize and summarize the calculations of each school, and then classify them one by one, adding some mechanics to some applications. This kind of thing is not a day's work, so it's not that easy. Now it's just hovering in the stage of addition, subtraction, multiplication and division.

"I used to hear that Luban made birds and could fly for three days without stopping. Now it seems that it is not a nonsense." Looking at the bamboo bird in Liu Yi's hand, Cui Zhouping smiled.

"Three days and three nights are a bit exaggerated." Liu Yi looked at the bamboo bird in his hand and said, "Maybe it's other principles."

I felt it was unreliable before, but after getting involved in the Mohist mechanism, Liu Yi is not sure now. His bamboo bird runs according to the clockwork method, and it will break down after playing twice. Perhaps Master Luban has other wonderful ideas, so it is unknown. He may be a person with an IQ of up to 25.

Liu Yi didn't care much about martial arts practice. Both little guys have their own inheritance. Besides, Liu Yi's ability to teach people how to practice martial arts may be a misleading child. The time has come to spring plowing season. The atmosphere in the entire Jingnan area gives people a different feeling than last year. It seems that the people have become much more active. This has nothing to do with the attributes of the city. Many families have children. Although the government issued the regulations that people under the thirteenth do not need to pay taxes, it is still more burdens for families with new students, but also more motivation and hope for life, right?

In the spring of the 16th year of Jian'an, in addition to the frequent harassment of Shanyue, it was a stable season, and most news from the north was heard at this time.

It is rumored that Cao Cao built a bronze croaker platform in Yecheng, which was ten feet high and extremely luxurious. It is hard for Liu Yi to imagine what kind of building it was. After all, the tallest building in Yueyang City is only seven feet high, and cement is also used. In such an era of backward productivity, there is no such thing as cement. How was it completed? For Liu Yi, this is an unsolved mystery. Did Boss Cao go back again? It was obvious that the new defeat in the Battle of Red Cliff was not long.

Liu Yi would occasionally take his wife and children and dogs back to the fishing village to live for a few days. Although Yueyang City is luxurious and comfortable, the fishing village also has a different rural scenery. Ma Su is still very busy. I heard that he has been busy planning for Shanyue recently, but Liu Yi didn't care about the effect. Now even if he loses to Shanyue, Liu Yi can bear the loss. He hopes that Ma Su can be defeated for a while.

But this idea is only about the idea. Even if Ma Su has no experience, he can completely abuse Shanyue by his mind. Just like Liu Yi has no experience in leading troops to fight, as long as his subordinates are powerful, he can still achieve a brilliant record of two thousand troops in the four counties.

He wanted Ma Su to suffer some small losses, but at least these mountains did not have the ability. By the end of April, Liu Yi received Ma Su's good news. The mountains in the four counties had been successfully subdued, with about 5,000 people. The rest did not dare to come and harass them if they had anything to do.

As for the process, in the aftermath of the good news, the whole city basically gave Liu Yi a sense of déjà vu, which was basically a relationship between Shanyue, using this to beat that, then let that beat this, and then came forward to comfort him. The soldiers were basically useless, and those Shanyue were almost like pants played by Ma Su.

This is not a match for the competition!

Looking at his daughter riding on Wangcai's back and laughing, Liu Yi sighed softly. It seemed that he had to find a stronger opponent for Ma Su. Shanyue... It seemed that it was not too challenging, and it also proved that Ma Su was indeed a good talent.

"Why are you sighing?" Lu Lingqi, who was studying needlework with Mrs. Wei, looked here in confusion and asked.

"It's nothing, it's just that the sky is about to change." Liu Yi shook his head, looked at the large clouds in the sky gathering here, stood up and said, "Go back to the house, it's going to rain."

The sun was gradually blocked, and the drizzling spring rain began to blur the lake's spring scenery with a layer of curtains. Standing in the attic, I felt a bit like a fairyland on earth.

A small boat quickly approached the fishing town in such a rainy curtain. The boat was the banner of Liu Bei's army.

"It seems that the peaceful days are coming to an end~" Seeing the boat quickly docking near the fish pond, a soldier in a straw hat and straw raincoat rushed straight to the place, Liu Yi looked at his wife and said.

When Lu Lingqi heard this, she didn't say anything, but she had a look of worry in her eyes.

"See the Lord of the House!" The soldier soon came to the attic, saw Liu Yi, and bowed and said, "The Lord of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of the House of

"Go and rest first, let's go tomorrow." Liu Yi looked at the fine rain curtain and sighed silently...
Chapter completed!
