"How is it? Do you understand?"

Half an hour later, Yu Yong also looked at Lu Lu and others with caring eyes. To be more specific, it was the caring eyes of mental retardation.

Yu Yong knew that he had not really understood the problem-solving process of the problem, and even whether he could understand it before graduating from college was between the two. In this case, he believed that the girls in the biology department who had never even studied differential geometry in front of him would never be able to understand it in his life. So, he just wrote down Gao Bozhu's explanation process according to the cat and painted the cat and repeated the explanation process. As for the explanation, whether he was wrong? Believe it or not, he said that he was the isotropic and uniform 3-dimensional single-connected manifold m^3 into 4 types, and then fabricated an Einstein space e^3, and would not even discover these girls on the other side?

He has this confidence!

After listening for a long time, Lu Lu said hesitantly: "Senior Brother, can you please write down the problem-solving process?"

Yu Yong simply pushed the pieces of paper that Gao Bozhu applied directly to Lu Lu: "Here, it's all here."

Lu Lu looked at the formulas that were full of ghosts and ghosts, and the mathematical terms that were like hammers and sticks were all over the place, and suddenly they were two big: "Is this a problem-solving process? Why does it feel like draft paper?"

What does it mean to feel like draft paper? It is clearly draft paper!

Yu Yong still pretended to be profound: "Don't worry! If you can understand, this is the problem-solving process; if you can't understand, even if you carve the problem-solving process and inlaid with diamonds, he still can't understand!"

"All right."

Lu Lu finally believed in the persuasion of professionals. There was no way, it would be impossible not to listen. Who made me know nothing?

At noon the next day, Lu Lu, who was still feeling pain, was waiting early at the entrance of Xueer Canteen. Seeing Jiang Shuiyuan coming from afar, he took the initiative to greet him: "Junior brother, why did you come!"

Master, junior brother? Are we very familiar with each other?

Jiang Shuiyuan's eyebrows were beating, and he still spoke gently: "Is there anything wrong?"

"Can't you look for you if you're fine? No matter what, we've met old friends both sides." Cinderella, who looks ordinary to below the average, used vulgar and stiff techniques to flirt with her. Unfortunately, her temperament, her conversation, and her appearance could not support her humor. The atmosphere on the scene was very awkward. In the burning eyes of people around her, she scratched her head: "Actually, I did the title you gave me yesterday!"

“Make it?”

Jiang Shuiyuan was shocked. Although he read the title casually, the content was still impressive. This should involve the manifold problem in general relativity. Before he could touch the edge, this freshman girl of biology actually made it silently? If you guess correctly, the School of Biology should not even learn differential geometry, right?

Could it be that every school has the legendary sweeping monk?

Could it be that the pretty little girl in front of me who is not stunningly beautiful is Dugu Qiubai, who is hiding in the city?

Jiang Shuiyuan asked tentatively: "What is the cosmic model you used?"

"Ferriedman model?" Lu Lu was not sure, but she only heard the name yesterday.

"!"

Oh, he is really a master! Jiang Shuiyuan immediately looked at this inconspicuous little girl Liang with admiration, and respected her tone: "Awesome, amazing! How did you learn differential manifolds? Do you teach yourself or?"

"Don't worry about this!" Lu Lu felt sweet as if she had received the recognition of the handsome guy, but she tried her best to keep a low profile. After all, she didn't dare to beat the stolen gongs and drums, and she would reveal her feelings after a little question. Then she took out the draft paper from her pocket and slapped it: "Hey, this is the solution to the problem. Take it back and understand it slowly!"

Jiang Shuiyuan opened those pages casually, and there were a bunch of nouns and equations written on them, which did not look like the problem-solving ideas at all. And judging from his shallow discrimination ability, it was not like the handwriting of a girl. He continued to ask: "Then why did you use the Ferridman model?"

This question is simple and simple. Just say that the Feridman model is the mainstream standard universe model.

But this question is difficult to say, because it involves the explanations of the origin and evolution of the universe, such as nuclear physics, particle physics, relativity, quantum mechanics, etc., and it is important to note that we have not yet discovered anisotropy in the residual background radiation. At this stage of cosmic evolution, at a sufficiently large scale, the distribution of matter can be regarded as isotropic and uniform, so the Feridmann model can be used when estimating the age of the universe.

——This is a bit beyond the margin of knowledge for freshmen in the biology department. Lu Lu was immediately puzzled: "Uh... this kind of problem, if you go back and slowly understand it, always eat the buns that others have chewed, how can you grow up healthily in the future!"

When she said this, she naturally showed her timidity. Jiang Shuiyuan smiled and folded a few pages of paper into the book: "Thank you!"

"Isn't it a bit too light to help you with such a big help?"

"Then how do you say thank you?"

"Traveling, you can do me a favor, too!"

Jiang Shuiyuan didn't expect that this young lady-in-law who looked ordinary was so tricky. She was indeed not good at looking at her: "Tell me, what can I help you?"

Lu Lu looked excited about the conspiracy: "That's right. I am also the deputy director of the Art Department of the Student Union of the Academy of Students. Isn't it almost the graduation season? The institute is preparing to hold a graduation party, and the specific work will be handed over to our Art Department for the process. Now there is a finale of a heavy figure, so I want to invite you-"

"Sorry, I'm busy with exams recently, I'm afraid I don't have time."

"Why don't you have time? At most ten minutes to perform a show. No matter how busy you are, can't you even get ten minutes? Do you know how much time and time I spent to do that question?" Thinking of his wallet that had lost a lot and the days when he was tight, Lu Lu couldn't help but feel sad and angry: "How can you be like this, a boy?"

Jiang Shuiyuan felt inexplicably: "If I remember correctly, you dirty my clothes first and then help me with the questions? Let's go back and forth, have a clear relationship, the facts are conclusive, and the handling is appropriate. It seems that there is no need to make any moral accusations against me, right?"

Lu Lu gritted her teeth: "At worst, I'll help you with another question!"

Jiang Shuiyuan didn't want to cause any trouble: "If you do it again, it would have to be Goldbach's guess!"

"mean!"

Just be stingy, it’s better than being angry in the future. Jiang Shuiyuan bypassed this girl who was not beautiful but thoughtful, and walked into the cafeteria to continue looking for food. Unexpectedly, the girl did not retreat, but followed her inseparably, lined up together, made meals, and had dinner together. What should I do?

Of course, I chose to ignore her.

After Jiang Shuiyuan finished his meal silently, looking at the girl following behind him, he decided to go to the library to search for the analytical geometry textbooks currently available in domestic universities. Although Liangjiang University is unknown and the library is also dilapidated, there are quite a lot of various textbooks collected in it. I don’t know if the school thinks that various textbooks are a necessity for students of the school, or because the schools collected a lot of textbooks before the merger. Now, once merged, it has become its current scale.

He used to pick two sets of the most well-known textbooks and found a secluded corner to read them. That's right, it was "flipping". Basically, he first looked at the catalog, then closed his eyes and thought for a few minutes, and then started to flip through the books. Soon, he turned one-third of the book.

Originally, Lu Lu saw Jiang Shuiyuan pick up a bunch of textbooks from the mathematics district, and subconsciously avoided a few steps, for fear that he would catch him and ask the previous question again. However, the people didn't even look at him, and they just flipped through books and played with them. They were also very interesting and well-like, so she plucked up the courage to come over and said, "Hey, what are you doing?"

Jiang Shuiyuan, who was almost interrupted, glared at her and did not answer her question.

"Are you reading a book?" Lu Lu asked persistently.

"I know, ask?"

"Do you usually read books like this? How effective is reading? How much can you remember? I feel that reading books like this, I can't remember anything!" Lu Lu was like a curious baby.

Jiang Shuiyuan directly banned: "Don't talk, keep quiet in the library!"

Lu Lu waved her fist so much that she was so angry that she wanted to go over and swear at him: This little fairy is the blessing you have cultivated for so many lifetimes, but she dares to ignore her. Who gives you the courage? Is it Liang Jingru?

The library is very quiet, the air conditioner is neither hot nor hot, and the buzzing sound of the lamp tubes is very hypnotic. Lu Lu, who is accustomed to taking a nap, was quickly sleepy and lit his head like a kowtow bug. After reading a book, Jiang Shuiyuan was about to get up quietly. As soon as he moved his chair, Lu Lu jumped up instantly like a husky who was stepped on his tail: "Where are you going?"

Jiang Shuiyuan frowned slightly: "Where am I going, do you care?"

"It's okay, I just ask casually, you can do whatever you want." Lu Lu yawned without any image, "Also, am I a girl or your senior sister, can you please be more polite when you speak?"

Jiang Shuiyuan was too lazy to pay attention to her, so he got up and walked out. Lu Lu immediately followed him and followed him. Jiang Shuiyuan was furious: "I want to go to the bathroom!"

"You go! I won't peek. I'm just waiting at the door."

Jiang Shuiyuan finally understood why "a good girl is afraid of tangling the man". Not to mention a good girl, even a hero in Liangshan, he has to be afraid of the opposite sex who is like a vine lingering around a tree! Like Wu Er Ge and Hei Sanlang, who are still the few who dare to take ruthlessness. Besides, killing people in a civilized society is illegal!

So he inexplicably missed high school life.

In my memory, the girls in high school are very simple and shy. Even the crazy fans are only brave enough to sneak over during class breaks and peek at them. When the bell rings, they still have to go back to their classroom honestly. Unlike now, the classroom is a vegetable market, and everyone comes and goes freely. It is said that some tough girls dare to break into the dormitory of boys!

Is the campus so big that I can’t even put down a little private space for boys?
