Chapter 46 Changed In order to prove himself, the old man took Zheng Fa and the others to another room. The door of this room is always closed, and Zheng Fa and his friends have never come in. The room was not big, about ten square meters. There was a row of tall bookshelves against the wall. The books on the shelves were placed in a very messy manner. There were also a few half-opened books on the floor and on the chairs. You can tell at first glance that this sloppy study belongs to this lazy old man. The only difference in the style of the painting is the desk in the corner of the room near the window. There is nothing else on the desk except a thick stack of paper and a pen holder full of pens. The most amazing thing was that the stack of draft papers was stacked neatly, like a piece of smoothly cut tofu. "Is this your new book?" Tang Lingwu also saw this pile of special drafts. The old man was now modest: "It's just an idea of mine. I've been writing it for several years." He turned to Zheng Fa and said, "I really don't have that much time. I made an appointment with someone to write this book before I retired, but it's been five or six years since I retired and I still haven't finished it." "People's Publishing House really called to urge us to pay, I didn't brag..." Facing Zheng Fa's suspicious gaze, he stammered, "At most I boasted one or two... five, six, seven, eight sentences."
Zheng Fa looked at the obviously different desk and nodded: "You really value this book." "I wouldn't say I value you that much. Like I said before, I'm not that good at math." The old man touched the draft paper on the table, thought for a while, and asked Zheng Fa, "Do you know why I've always been reluctant to teach you?" “Am I a slow learner?” "Well, stupidity is one of the reasons." The old man has always been straightforward about his contempt for Zheng Fa's IQ. "Because I am taking the college entrance examination now?" Zheng Fa guessed again. "That's one reason, but the main reason is that you're not the type of person who does math." Zheng Fa was stunned, not quite understanding why the old man said that. "I'm not saying that you have a problem with your character, but you shouldn't be too goal-oriented when doing mathematics. And you..." The old man glanced at Zheng Fa: "Do you want to learn topology? Or are you here for those weird patterns?" Zheng Fa frowned. "Wouldn't it be better to be more practical?" Tang Lingwu muttered. "What is mathematics?" the old man suddenly asked. "what?" "The essence of mathematics is to study things that do not exist." The white old man said to the two people, "Do imaginary numbers exist? Do natural numbers even exist in nature? Can points, lines and planes in geometry be found in nature?" Zheng Fa didn't say anything. He still didn't understand what the old man wanted to say, but the old man seemed to have found the feeling of being a university teacher: "Mathematics is essentially an abstract, non-existent axiom system. To some extent, you can regard it as a set of purposeless game rules invented by humans. It just happens that this set of rules can explain some things in this world," he said incessantly. "So many theoretical mathematicians look down on applied mathematicians. We agreed to be the mothers of science together, but why are you so weak..." Looking at the young faces of Zheng Fa and Tang Lingwu, the old man swallowed the indecent word on his lips and changed it to another word. "Lost women." Seeing that Zheng Fa still didn't understand, the old man explained more clearly: "If you are studying topology for those patterns, then let me ask you, have you ever thought about whether topology can really analyze all these patterns?" Zheng Fa nodded. "This is the tricky thing about science. Even if you are right 10,000 times, you can't be sure that you are right. If you are wrong once, you are really wrong. At that time, do you still want to learn topology from me?" Zheng Fa understood what he meant. The old man was beating around the bush, trying to persuade him not to lose sight of the main point.
"I want to learn, even if I learn slowly." Zheng Fa said slowly. Even without these talismans, he was still very interested in the knowledge of this world. "Then I suggest you learn from me." Seeing that he looked determined and didn't seem to be lying, the old man was relieved. He comforted Zheng Fa, which was rare, "It's okay to go slowly. You haven't fully mastered the high school knowledge. Topology is a second-year undergraduate course at Jingcheng University. You must have at least the knowledge reserve of a freshman to really get started. It's normal to be slow now." The old man had good intentions, but Zheng Fa still refused: "But I still want you to help me analyze those patterns." Zheng Fa thought very clearly. He was interested in mathematics, but he only used it as a tool. Just like the old white man's brain. "I really don't have the time!" Zheng Fa turned to look at Tang Lingwu who was standing beside him, pointed at her and asked, "I remember you said that she has already learned college courses?" "Ok?" "Since I have to start from high school, why don't I learn from her?" There is no problem that can't be solved by borrowing a brain. If that doesn't work, just borrow another one. Tang Lingwu was stunned for a moment and pointed at herself: "Me?" "I'll teach you martial arts and you'll teach me math, okay?" Tang Lingwu looked at the old man Bai hesitantly. The old man frowned, but did not deny Tang Lingwu's ability: "That's a good idea. If you have something you can't teach, just ask me. In fact, if you teach him, it will greatly improve your understanding of those knowledge points, but it will waste your time..." "I'll teach you! I want to learn martial arts!" "Don't you want to?" the old white man snorted. Tang Lingwu didn't say anything, just smiled with her lips pursed. Zheng Fa took out the draft books with a smile: "So which one should we start with today?" The old white man was stunned. He pointed at Tang Lingwu: "She has become your teacher and can also practice martial arts." "Correct." "She won't scold you anymore, and I can't scold you. Not only will you not be scolded, but you'll also have a beautiful girl as your teacher, and me as your part-time worker." Zheng Fa smiled and said, "It seems so." "And I, not only have to work for you, but I also lose the joy of scolding you?" The reasoning was so flawless that it made the old man look desperate. "At least you learned your lesson." Zheng Fa patted the old man on the shoulder and said, "Next time, don't threaten to drop out of school." …… Because he had to teach Tang Lingwu how to practice martial arts, Old Man Bai’s home was no longer spacious enough. Several people came to the small open space where the old man Bai had witnessed Zheng Fa getting started with the Songhe Posture.
The old man in white continued to practice Songhe Posture with great difficulty, and his expression was much more serious than before. Zheng Fa stood in front of Tang Lingwu and instructed her how to stand. They were very close to each other, and her nose felt itchy when being brushed by each other's hair. A faint fragrance came from the little girl. He was not affected and quickly collected his mind. Then he discovered the difference in this world - after practicing the "Spirit Crane Body", once he circulated the Qi in his body, he would feel a force in the void responding to him in the Xuanwei Realm. But this world doesn’t have that! The difference between them made Zheng Fa wonder. "Zheng Fa, you... smell so good!" Ok? Tang Lingwu seemed to feel that her words were too obscene, and her eyes wandered around. Zheng Fa's eyes fell on her seriously, probingly, as if he wanted to see another old friend in her face: ...Gao Yuan, is that you? …… "Zheng Fa! I found something strange!" Gao Yuan saw Zheng Fa, trotted over to him, and put his head in front of Zheng Fa, as if he wanted to whisper something to him. "Stop, stay away from me." Zheng Fa closed his eyes. "?" "I'm not used to you suddenly becoming so ugly." Gao Yuan touched his confused face, quickly put aside his confusion, and whispered, "I haven't changed, it's the Seventh Young Master who has changed!" "Changed? How?" Zheng Fa was a little curious when he heard it. "Becoming..." Gao Yuan seemed to be having trouble describing it, scratching his head, "Becoming, a bit like me." ...What a coincidence, I also know someone who looks a bit like you. (End of this chapter)
