Slender bamboo silk flew between his fingers, Liu Yi's eyes looked at the two children who were scuffling together in the martial arts room with interest, at first the two were still holding their own wooden knives and wooden spears, but probably after the fight, they felt uncomfortable, and directly threw away their fists and feet to fight, and there was no intention of fighting, Liu Yi felt that it was normal for children to fight, as for the cause, it seemed to be arguing about who was more powerful in the father of the two families, trying to persuade each other, but in the end, it was obvious that he wanted to convince the other party and make the other party admit his point of view.

The world of children, that's it, there is no reason to talk about it, it seems that no matter whether it is the official history or romance, Zhang Fei and Guan Yu have no conclusion on who has higher martial arts, but in terms of reputation, whether it is now or in the future, Guan Yu is more famous.

"No matter?" Glancing at the trap bird in Liu Yi's hand, Cui Zhouping threw a nut into his mouth and asked.

"What's the matter? I would like to know too. Liu Yi asked rhetorically: "Speaking of the fact that people and horses have been busy these days, and your feet don't touch the ground, are you a little undutiful as a county man?" ”

Ma Tan's talent is good, but the four counties are busy with Ma Tan, but it is Cui Zhouping, who has not even returned to the governance office recently, so there will be no problems, right?

"At first, it was really busy, but now it's basically sorted out, just go back regularly to get stamped, go back four or five times a month, it's almost enough." Cui Zhouping didn't care.

So, that's why you come here every day?

Liu Yi didn't say it directly, but said, "Otherwise, bring your sister-in-law and their wives together." ”

"Not so good." Cui Zhouping nodded thoughtfully and said, "But since Bo Yuan has been invited, it is better to obey his fate respectfully." ”

Liu Yi: "......"

He suddenly found that he didn't know when Cui Zhouping's emotional intelligence had become lower, or his skin had thickened.

Cui Zhouping turned his head to look at the bamboo bird that was gradually forming in Liu Yi's hand, and teased: "This is not like Bo Yuan's craftsmanship. ”

The bamboo bird is only a rough outline, so that people can see that it is a bird, but it is not as lifelike as the carvings that Liu Yi has done in the past.

"Playthings don't need to be vivid." Liu Yi didn't explain either, the craftsman is a separate skill, and he has only recently figured it out, with a pair of skillful hands, he can control it, but the attributes have not yet come out, let alone come alive.

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

"Who said it was a joke?" Liu Yi pulled the beak of the bamboo bird, stretched out his hand, and the bamboo bird poofed, in Cui Zhouping's stunned gaze, fluttered its wings, flew upward, hovered above the heads of the two, and for a while it was like a real bird, and never fell.

"How is this done?" Cui Zhouping was surprised.

"Mechanics, I told you, there is also a powerful existence in the air, relying on the flapping of wings, imitating the movements of birds, and relying on the power of the machine inside......" Liu Yi said a lot of numbers, and Cui Zhouping listened to it for a while and did not fully understand the law.

But he frowned and said, "If this mechanical bird is enlarged and made of wood, can it carry people into the sky?" ”

Flying has always been something that human beings 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 want to use bamboo silk to make it?" ”

Looking at the bamboo bird that flew for a while, it began to descend slowly, Liu Yi sighed: "Because the bamboo silk is light, if it is replaced with a wooden plank, it will not be able to fly, that is, the internal organs do not dare to do more, if it is enlarged, it is feasible to use bamboo silk to do, but don't say that it is manned, it is tied to a stone that can't go up, and the bamboo silk is fragile and not suitable for manning." ”

Flying this kind of thing, Liu Yi also thought about it, if there are enough conditions, I don't know what will happen if I make a hot air balloon or a glider with the blessing of attributes, but these thoughts are just to think about it, don't think about it for the time being, there are many problems to be solved, the glider is simple, but there are no parameters to make it, there is no guarantee of safety, who will be the test product? It's easy to get killed.

"Uncle Bo Yuan, what is that?" Guan Xing and Zhang Bao, the two little guys, stopped beating each other at some point, ran over with a blue nose and swollen face, and looked at the stopped bamboo bird in Liu Yi's hand.

"Want to either?" Liu Yi looked at the two boys and said with a smile.

"Yes!" Guan Xing and Zhang Bao have also been familiar with Liu Yi during this time, not as shy as they were at the beginning, and they didn't hide it at the moment, and nodded.

"Memorize the multiplication formulas I taught you, and be able to write them down silently, one for each person." Liu Yi said with a smile.

The ninety-nine multiplication table is the cultural class taught by Liu Yi during this time, although it is not difficult, but it is quite practical, in this era, as a general, you must often count the number of people, this multiplication table is enough.

"Good!" When Guan Xing Zhang Bao heard this, he said in unison, that thing is not difficult for them, Liu Yi has already told them about the algorithm.

"Your new arithmetic book is complete?" Cui Zhouping looked at Liu Yi and smiled.

"Not yet, it's just some simple algorithms, and I'll slowly improve it in the future." Liu Yi shook his head, he is now trying to simplify the translation of the various arithmetic scriptures, summarize them, and then classify them one by one, adding some mechanical applications, this kind of thing, not a day's work, which is so easy, now it is just wandering in the stage of addition, subtraction, multiplication and division.

"In the past, I heard that Luban made birds and could fly for three days without stopping, but now it seems that it is not a lie." Looking at the bamboo bird in Liu Yi's hand, Cui Zhouping said with a smile.

"Three days and three nights is a bit exaggerated." Liu Yi looked at the bamboo bird in his hand and said, "Maybe it's something else." ”

I didn't think it was credible before, but after coming into contact with the Mo family's tricks, Liu Yi is not sure now, his bamboo bird runs according to the clockwork method, and it will break if he plays twice, maybe Master Lu Ban and his old man have other wonderful ideas, then it is unknown, it may really be a character with an IQ as high as two hundred and five.

Regarding the practice of martial arts, Liu Yi didn't care too much, the two little guys have their own heritage, besides, Liu Yi's ability to really teach people to practice martial arts, it may be the wrong child, the time has come to the spring ploughing season, the atmosphere in the entire Jingnan area feels different from last year, it seems that the people have become much more positive, which has nothing to do with the attributes of the city, many families have children, although the government promulgated the regulations, people under the age of thirteen, do not need to pay taxes, But in terms of families with new children, there are still more burdens, but at the same time, there is more motivation, and there is hope for life, isn't it?

In the spring of the sixteenth year of Jian'an, except for the frequent harassment of Shanyue, it was a stable season, and most of the news from the north came at this time.

It is rumored that Cao Cao built a bronze bird platform in Yecheng, as high as ten zhang, extremely luxurious, Liu Yi can hardly imagine what kind of building it is, after all, the tallest building in Yueyang City is only seven zhang high, and cement is also used, ten zhang high copper bird platform, in such an era of backward productivity, there is no such thing as cement, how did it be completed? For Liu Yi, this is an unsolved mystery, is Boss Cao floating again? Obviously, the new defeat in the Battle of Chibi did not take long long.

Liu Yi occasionally takes his wife, children and dogs back to the fishing village to live for a few days, although Yueyang City is luxurious and comfortable, but the fishing town also has a different rural scenery, Ma Jian is still very busy, I heard that he has been busy calculating Shanyue recently, but what the effect is, Liu Yi didn't care, now even if he loses to Shanyue, Liu Yi can afford the loss, he hopes that Ma Jian can lose for a while.

It's just that this idea only stays on the idea, even if Ma Jian has no experience, he can completely abuse Shanyue in terms of heart and eye, just like Liu Yi has no experience in leading troops to fight, as long as his subordinates are strong, he can still play a brilliant record of 2,000 people in Ma Ping and four counties.

He wanted to let Ma Jian suffer some small losses, but at least these Shanyue did not have this ability, and at the end of April, Liu Yi received a good report from Ma Tan, and the Shanyue in the four counties had been successfully subdued, about 5,000 people, and the rest did not dare to come and harass them if they had nothing to do.

As for the process, anyway, in the good news after the fact, the whole city basically gave Liu Yi a sense of déjà vu of playing monkeys, basically dividing the relationship between Shanyue, using this to fight that, and then letting that fight this, and then come forward to appease, the soldiers and horses are basically useless, and those mountains are almost used as pants by Ma Tan.

This year's opponent can't do it!

Looking at his daughter who was riding on Wangcai's back and laughing, Liu Yi sighed softly, it seems that he has to find a stronger opponent for Ma Tan, Shanyue...... It doesn't seem to be too challenging, and it also proves that Ma Jian is indeed a good talent.

"Why is the husband sighing?" Lu Lingqi, who was studying needlework with Mrs. Wei, glanced over in confusion and asked.

"It's nothing, it's just that the sky is about to change." Liu Yi shook his head, saw that the large clouds in the sky were converging in this direction, stood up and said, "Go back to the house, I'm afraid it's going to rain." ”

The sunlight was gradually blocked, and the spring rain began to cover the lake with a curtain of spring.

A small boat, in such a rainy curtain, quickly approached the fishing town, and the boat was playing the flag of Liu Bei's army.

"It seems that the days of peace are coming to an end~" Seeing the boat quickly docking near the fish pond, a soldier with a panting hat and a robe walked straight here, Liu Yi looked at his wife and said.

When Lu Lingqi heard this, she didn't speak, but there was a little worried look in her eyes.

"See the Prince!" The soldier soon came to the attic, saw Liu Yi, bowed and said, "The lord is in a hurry, please leave as soon as possible and go to the public security to meet the lord." ”

"Let's go rest first, and leave tomorrow." Liu Yi looked at the dense rain curtain and sighed silently......
