Sun Ce leaned crookedly on the desk, and Sun Quan, Lu Yi, Lu Meng and others sat around, watching Xu Yue explain his research results intently. Xu Yue was very excited, his bloodshot eyes were frighteningly bright, his face was pale, but there was an unhealthy flush, and the corners of his mouth were full of white foam, even on his beard, which was far from his usual elegant image, and he explained with spittle.

Although Sun Ce didn't say a word, he was so impressed. He originally thought that without a precision timing tool, Xu Yue would not have been able to come up with a formula for free fall, but he now knew that he had underestimated the ancients and underestimated Xu Yue's IQ. Xu Yue successfully bypassed the obstacle of timing, and not only came to the conclusion that the speed of the free fall was proportional to the square of time, but also to obtain that coefficient.

His number was five, which was very close to the correct answer.

The method he used was a diagram, assuming that the horizontal velocity was constant, dividing the curve of the fall of the iron ball into several equal parts, and then calculating the distance in the vertical direction. The method was so simple that people couldn't believe it, and even Sun Ce, a traverser, felt incredible.

It can be seen that some people are naturally smarter than others, especially those who study mathematics, and the brains of people in the Three Kingdoms era and people in the twenty-first century are essentially no different. The traverser has an advantage in knowledge, an advantage in insight, and no advantage in IQ.

Not only that, Xu Yue also adjusted the weight and height of the iron ball to derive the relationship between potential energy and kinetic energy - the terms he used potential and velocity were changed to potential energy and kinetic energy under Sun Ce's "suggestion". In the past two days, he has become obsessed with the game of pool again, because he has discovered that when two iron balls of the same size collide, if one iron ball is stationary, the other iron ball can perfectly transfer kinetic energy to the stationary iron ball. You can't do this if the two balls aren't the same size.

He felt that there must be some kind of mathematical relationship in this, and he wanted to solve this mathematical relationship.

Xu Yue is worthy of being the master of mathematics in the Han Dynasty, not only good at research, but also good at imparting knowledge. He not only explained his experience in a simple and straightforward way, but also successfully expanded it further, and talked about several similar mathematical problems one after another. Not only Sun Quan and Lu Yi listened attentively, but even Lu Meng and others who were not very culturally qualified listened to it with relish.

If it weren't for the fact that he was too tired, Sun Ce really wanted to listen to it for a while. Seeing Guo Jia standing at the door with his hands behind his back, Sun Ce interrupted Xu Yue. stood up, took Xu Yue's arm, and said with a smile: "Mr. has worked hard." However, there are still many problems waiting for you to study, you must pay attention to take care of your body, combine work and rest, and not be tired. ”

"Not tired, not tired." Xu Yue was full of smiles, but he couldn't help but yawn. "General, I have a reluctant request."

"You say."

"I want to write a book that collects arithmetic from all over the ages, and divides it into categories, all in one."

"Okay, do you want some fees?"

"I don't need it for the time being, I need some books to help copy, preferably ...... Those who can read books. ”

Xu Yue said as he blinked, rare and approachable. As soon as Sun Ce saw it, he knew that what he was asking for was definitely not as simple as money. Xu Yue concentrates on his studies and does not have high requirements for the quality of life, and the money he gives him is enough for his family to have no worries about food and clothing.

"If Mr. Gonghe has any request, even if he says it bluntly, as long as he can agree, I will definitely agree to you."

"I ......" Xu Yue licked his lips and stopped talking.

"Shuzuo no, there is a serious shortage of people who have read books in the camp now, and no one gives it to you." Guo Jia walked over and raised his hand. "Go to the baggage camp to find out, there must be some literate and hyphenated officials and slaves, whoever you fancy will be taken away, just go to the person in charge to prepare a case."

Xu Yue's eyes lit up and stared at Sun Ce. "Really?"

Sun Ce is not stupid, as soon as Guo Jia spoke, he understood what Xu Yue meant. Xu Yue must have taken a fancy to which woman was copied from the Cao family and the Cai family. Xu Yue himself has a wife and children, but Xu Yue himself is a very ordinary scholar, and his wife's family background is also very ordinary, she has no culture, and she only knows how to handle housework. Xu Yue came this time to have a trial component, so he didn't bring his family here, and his life was not too convenient. There are officials and slaves who have not copied from each family in the baggage camp, and it used to be regarded as a powerful family, and there are many women who are literate and hyphenated, and most of them have good appearance, Xu Yue has more contact with the baggage camp, probably because he fell in love with a beautiful woman who knows books and etiquette, and pities her for being unfortunate and wants to save her.

Sun Ce teased: "Of course, as long as Mr. Gonghe doesn't miss the right thing." I'm still waiting for the results of his research to improve the stone thrower. ”

Xu Yue was overjoyed, gave up his hand again and again, and went happily.

Guo Jia waved his hand quietly, and when Lu Meng and the others saw this, they withdrew from the big tent one after another and stayed outside the tent, leaving only Sun Quan and Lu Yi in the tent. Lu Yi also wanted to leave, but was stopped by Sun Ce and asked him to listen together.

"General, Xun Yu stole Nanyang and changed the law in Chang'an."

"Oh? What did he do, let's hear it. ”

Guo Jia took out a piece of paper and handed it to Sun Ce, on it was the news that had just been copied, there were more than a dozen, the content was relatively brief, but all aspects were very thoughtful, obviously not the kind of news that ordinary meticulous work could inquire. Sun Ce glanced at Guo Jia, with a hint of inquiry in his eyes.

"News from Zhong Xuan." Guo Jia said.

"Zhong Xuan?"

"That's right, the Zhong family, like my Guo family, uses the law to pass on the family, and Zhong Xuan's knowledge is also biased towards the Legalist, so he has not been taken seriously, and he is still a Huangmen squire in his forties. He originally planned to return to Yingchuan, but it happened that Xun Yu changed the law and recommended him to the Son of Heaven, so he didn't come, but asked his nephews Guo Yuan and Guo Wu to bring a book. Guo Yuan and Guo Wu are my brothers, and their martial arts are not bad, especially Guo Wu, who has worshiped famous teachers and traveled abroad for several years, according to himself, he has never met an opponent. This kid is a little arrogant, and he doesn't like to speak. ”

Sun Ce smiled. This Guo Wu shouldn't be as simple as not being able to listen to what he says. "The artist is bold, where is the person, let him come."

"Outside, I asked Zhong Kang and Shu Zhi to teach him a lesson, lest he not know the height of the sky and the thickness of the earth and collide with the general."

Sun Ce was silent. Under his command, Xu Chu was the first in foot combat, Chen Zhi was the first in cavalry combat, and Guo Jia asked the two of them to try Guo Wu, which shows that this Guo Wu does have some real skills. However, he didn't take this matter to heart, there were only a handful of people who could defeat Xu Chu in foot combat, and there were not many people who could win Chen in cavalry combat. Chen Zhi's talent is not bad, and he practices seven kills every day, and he is well-trained, even if he fights against Guan Yu and Zhang Fei, he will not fall behind. Martial arts is also a kind of technique, in addition to talent, it also requires scientific and rigorous training, and it is necessary to often carry out confrontational practice, otherwise it is difficult to maintain the best competitive state. Masters are basically unreliable in the people, and the real masters are either in the military camp or as guards around some powerful people.

After reading the briefing, Sun Ce handed it to Sun Quan and Lu Yi, and when they finished reading them one by one, he said, "Fengxiao, do you think Xun Yu's change can be successful?" ”

Guo Jia laughed. "General, changing the law is a big deal, and it is impossible to achieve it without the strong support of the king. The Son of Heaven may support him, but the Son of Heaven is young and has limited influence, if he wants to support Xun Yu like Qin Xiaogong supported Shang Yang and Emperor Xiaowu supported Sang Hongyang, it would be five years at least and more than ten at most, but whether Xun Yu could survive these five or ten years was hard to say. Even if he could, five or ten years later, the general's foundation was solid, and it was time to let go of his hands and feet and fight him. ”
