Ting Fang was depressed to death, it was a very happy thing to meet her relatives who she had never seen, but the other party made up for himself with a confident face, and he hurt everyone very badly. Ting Fang looked at the sky with tears in her eyes, where was her sister miserable...... My sister's crazy Ye Mansion is almost out of place, okay! She rushed with her uncle, and she was fine.

When she got home, Xu Jingchang sat in her study with a small radish head on one side. What's going on?

Xu Jingchang saw Tingfang coming back, and said with a smile: "Is the shaking done?" ”

Ting Fang was embarrassed: "Didn't Niangniang say that she was not in a hurry?" ”

Xu Jingchang smiled and said: "His Royal Highness King Fu said, you should be so refreshing, you can get it in one night at most." ”

Nima! All slave owners should be hacked to death! Ting Fang said bitterly to Xu Jingchang: "I don't have a workshop at home!" A carpenter came! ”

Xu Jingchang said: "I know, so I'm not here?" ”

Ting Fang was about to cry: "Overseer? ”

Xu Jingchang nodded.

Tingfang: "......"

After a while, Ting Fang said: "Seven girls, Brother Gong, you two are looking for another place, I have to work." ”

Ting Wu said: "You two are alone in the same room, don't you have to shy away?" We're out of the way. ”

Avoiding the balls, my sister now just wants to deal with the slave owners quickly. Xu Jingchang also had something to say, so he said: "It's not cold horizontally and vertically, the doors and windows are fully open, just ask Ping'er An'er to stay at the door." You two can find another place. Get out of the way. ”

Ting Wu pouted and complained: "It's all you, and my sister's gossip is endless." ”

Ting Fang said: "There is nothing in the world, and mediocre people disturb themselves." Ignore him. ”

Xu Jingchang smiled silently. After the two children withdrew to Chen Gong's room, he said: "Your Highness means that you have to do your best." It must be seen by the mother. ”

Ting Fang frowned and said, "You changed your mind." ”

Xu Jingchang was silent for a long time before he said: "Your Highness has grown up, so it's not good to mess around." "Hehe, His Royal Highness King Fu recently, it's a little scary. The loss that can't be hidden in his heart, in fact, King Fu is already his only surviving relative.

Ting Fang didn't have as complicated feelings for King Fu as Xu Jingchang, but seeing that Xu Jingchang was not interested, he didn't speak again. Grab a brass pen and compass ruler and draw three views little by little. Shaking is essentially a fixed pulley, and it is easier to understand the sliding **. The moving pulley is a bit against the sky in terms of thinking. The fixed pulley changes direction, and the movable pulley changes the "mass". The hatchback combination can save a lot of effort. The common sense that is taken for granted in modern times was not many people who understood it in ancient times. Even if it is discovered, there is no systematic theory, so it is particularly easy to be lost. For example, the Bianhe Hongqiao, which once amazed the world, is regarded as the ultimate in ancient mechanics. However, it is still a craft not a science, and the craftsman is lost when he dies. When it came to the Qingming Shanghe map copied by the Ming and Qing dynasties, the bridges in it were all stone. Stone arch bridges are either bad, or they are too demanding on the foundation, unlike wood, where bridges can be built.

Therefore, in fact, pulleys appeared in ancient times, but they were not used. Ting Fang only needs to draw all the internal and external structures of the pulley, and there is no need to explain much, and the craftsman can understand it in seconds. The difficulty is that several pulleys need to be matched in a well, and how to combine the pulleys. After Ting Fang finished writing the principle, he handed a stack of paper to Xu Jingchang: "The theory is like this, but how to use it well, you still have to realize it." ”

Science and engineering, science and engineering, science and engineering can work together to do something truly meaningful. Xu Jingchang took the drawings and turned them page by page. After reading it, I had a rough idea: "Let's try it." ”

Isn't this nonsense, engineering monks are real dogs, don't expect to achieve results in the next life if you don't do real things.

Xu Jingchang called Ping'er and said, "Your Highness just went to my house to ask for the abacus, and the two of them are now chatting around in the gatehouse outside, you give them the drawings drawn by your girl, and tell them to send them to the workshop immediately." Let's make that first, and I'll go back and see. Wood and copper and iron are done, hurry! ”

Ping'er was originally from the palace, and he knew King Fu's temperament. I immediately picked up the drawings and trotted all the way outside.

Ting Fang crossed his arm and asked, "What else is going on?" ”

Xu Jingchang took out a toy snail from his sleeve: "Give it to you." ”

Ting Fang took a look, it turned out to be a clockwork. Tighten the clockwork, and the little snail slowly crawls forward. Ting Fang smiled: "It's not appropriate to send me, it's just right to send Xiaoba." Thank you, brother. ”

Xu Jingchang smiled: "I did it for a long time to make it, you can play when you get started, Your Highness has been tossing for a long time." ”

Tingfang thought it was imported, but she didn't expect it to be original. Immediately looked at Xu Jingchang with admiration: "You are amazing!" ”

Xu Jingchang was extremely proud in his heart, but he had nowhere to tell, so he had to come and talk to Tingfang. Seeing that Tingfang really understood, he sold Guan Zi and said, "Do you know how I learned it?" ”

Ting Fang tilted her head and thought for a while: "Dismantled someone else's, put it back little by little?" ”

Xu Jingchang shook his head: "I've been doing it, but I can't do it." Your waterwheel inspires me. I knew there must be gears in it to move, but I was too embarrassed to tear down His Highness's chiming bell. Coincidentally, all the toy gears you made that day were exposed. I studied it for a day and a night, and I made it last night. ”

Ting Fang supported his forehead, and the engineering monks were really like birds: "How long have you been up?" Would you like to take a break? ”

"It's fine." Xu Jingchang smiled at the corner of his mouth, "I can't sleep with joy." Come and talk to you. Again, do you see if there is anything else that can be changed? ”

Ting Fang shook her head: "I don't know much about that thing." You slowly learn arithmetic, and when you have my level, you will get twice the result with half the effort. ”

Xu Jingchang nodded: "Arithmetic is a good thing, how much effort can be saved." When I was a child, I didn't learn well, and if I wanted to make something, I either thought about it in my head or tried it little by little. When you learn arithmetic when you are older, you can do the math first and then do it, or do it while you do. It's a pity that you don't have the ability. ”

Ting Fang said happily: "It's okay, I'll teach you." ”

"Thanks!" After Xu Jingchang finished sharing, his mood index rose, so he asked Tingfang, "You weren't very happy when you came in before, what's wrong?" Who made you angry again? ”

Ting Fang waved his hand: "It's good if Your Highness doesn't give me anger, and the rest is a trivial matter." After speaking, he teased Xu Jingchang again, "If you are a senior sister, you will be a pair with King Fu." It's a good match. ”

Xu Jingchang had just been intimidated by King Fu, and said angrily: "The little junior sister is the most suitable, why don't the little junior sister be the princess of Fu." ”

Ting Fang laughed: "Confidant! ”

Xu Jingchang let out a long sigh: "It's boring to grow up." He couldn't help but say, "His Royal Highness treats me really well, but during this time, I just scared him, knowing that he wouldn't do anything to me, I still scared him." "Xu Jingchang is even more lonely than Tingfang, and he can only suffocate everything in his heart. But he was so uncomfortable that he didn't know what he was afraid of. King Fu treated him the same as before, but he just felt different. I can't tell if it's intuition or hallucination. Judging from the attitude of the people in King Fu's Mansion towards him, I don't know if King Fu has changed or he has changed. couldn't tell the truth, the cut was still messy, Xu Jingchang felt that he was about to collapse.

Ting Fang pouted: "It's all resentful." ”

Xu Jingchang glared at Ting Fang.

Ting Fang smiled: "Don't stare at me, I'm not stupid and bold, I dare to say anything." ”

Xu Jingchang, hehe.

Ting Fang spread his hands.

Xu Jingchang said: "Girl, what are you afraid of, Your Highness?" ”

Ting Fangkai mocked: "Open your mouth, shut up Your Highness, Princess Fu is not as affectionate as you." ”

Xu Jingchang was speechless: "What is the name of His Highness if you don't call it?" ”

"His Royal Highness King Fu!"

Xu Jingchang looked at Tingfang with disgust: "How many lives do you think I have?" "Tsundere dissociates herself from the prince who grew up together and looks for death. He changed his name to His Highness, and Ting Fang found out. Even if His Royal Highness has grown up, he will wait to be thrown back to the Dingguo Mansion by the Fu King to make soup and drink it for the Duchess of Dingguo. The king wants the minister to die, the minister has to die, the father wants the son to die, the son has to die, what a fuck!

Ting Fanghe: "Then you still ask me why I'm afraid of His Royal Highness King Fu?" ”

Xu Jingchang was annoyed, and kowtowed heavily on the table: "If he hadn't been His Royal Highness, I would have been stewed by my stepmother." But he is His Highness, and I ......"

Ting Fang looked at the beautiful senior brother with a sympathetic face, tsk, if it was someone else, she would have been thrown out by her, but he is a handsome guy, and he really can't do it! King Fu is the king of Xu Jingchang and the king of Dingguogong, so Dingguo Gong has no choice but to Xu Jingchang. But at the same time, since there is a difference between a monarch and a minister, there is no way to simply be brothers. Xu Jingchang is so hard, he has no relatives! It's miserable! Ting Fang leaned on the table and asked, "You don't have any other acquaintances?" ”

Xu Jingchang said weakly: "Yes, I went to the frontier." ”

Ting Fang asked curiously: "Who!" ”

"Your Highness's little uncle." Xu Jingchang said, "It's not pro, you know that His Royal Highness's mother family is the Liguo Mansion, right?" ”

Ting Fang nodded.

Xu Jingchang said: "His Royal Highness's little uncle is the old son of the first prince of the country. Xianli Guogong couldn't give birth to a son, Xianli Guogong was gone early, and when he was almost about to succeed, his concubine was pregnant. pregnant. Born a brother. You can't let a concubine raise a child, and it's even more difficult to marry and fill the house when you're old. I put it in my mother's house and raised it. The mother also brought it herself. Later, Niangniang entered the palace and gave birth to His Royal Highness, and Li Guogong, who was still the prince at the time, entered the palace as a companion. Because he is an uncle, he can control His Highness. Later we were added. But everyone else has been almost cleaned up by him, my uncle's family is a few, especially cowardly, Ren beats, scolds, and bullies, and actually mixes up for a while, and now His Royal Highness is really bored and looking for them to play. ”

Ting Fang asked very respectfully: "And then?" ”

Xu Jingchang continued: "No, then later, Li Guogong was gone, and the prince went home to keep filial piety and found that the family was already poor and couldn't open the pot." When I was a child, I could mix with my uncle, but when I grew up, I couldn't still eat my uncle's food, right? He was good at martial arts when he was a child, and he went out of filial piety to enter the palace and told the saint that he wanted to join the army and go to Datong. The saint is very happy, and he will really send it to Datong. He's quite capable of fighting, and now he's a general soldier. We haven't seen each other in years. ”

Ting Fang praised: "It's a man!" Why don't you go along? ”

Xu Jingchang said: "There are several reasons. One is that I am small; second, my stepmother didn't let go, afraid that I would come back after earning meritorious service; The three concubines refused, this was purely worried about me. Besides, His Royal Highness King Fu doesn't do it, and no one plays with him. Saying that he remembered the old days, "Uncle Xiao is very good, you will know when you see it in the future." ”

Ting Fang twitched the corners of her mouth: "What does it have to do with me?" ”

Xu Jingchang chuckled: "Yes." ”
