Math professor returns to routine

Chapter 396 Same as 9, Ru Hexiu

Sunday afternoon.

After dinner.

Separating from Tang Wan in front of the gate of the girls' dormitory, Lu You didn't stay too long and quickened his pace to return to the dormitory.

The outdoors in summer is really not a place for humans.

Not to mention walking, even if you stand in the shade of a tree, you will sweat profusely.

In particular, Lu You was carrying a schoolbag with a laptop in it. The heat could not escape at all, as if he was in a furnace.

Lu You crossed two steps in one step and went upstairs as quickly as possible.

As he passed the corner between the third and fourth floors, a familiar yet unfamiliar voice called to him.

"Lu You?"

Lu You looked up.

He saw a tall, thin boy wearing short sleeves, shorts, slippers and carrying a garbage bag walking towards him.

"It's really you! What a coincidence!"

Lu You's mind moved and he immediately remembered the boy's name.

Su Xinghe.

Like him, from Yue Province.

Zhang Zhichuang's good friend is very good at physics.

Lu You raised the corner of his mouth and said, "Long time no see. I didn't expect you to be at Capital University as well."

Su Xinghe stopped in front of Lu You and said with a smile: "Capital University is number one in the country in physics, where else could it be if it wasn't here?"

"Isn't there another neighbor?"

"The school next door is strong in applied sciences. My goal is condensed matter physics, so this is the place that suits me."

Condensed matter physics is one of the largest and most important subdisciplines of physics today.

In China, people who don’t know it well may think it is an unpopular subject, but in fact it is not.

In recent years, the popular superconducting materials, quantum computers, electric vehicle batteries, etc. all involve condensed matter physics.

Lu You has a certain understanding of this, but not much. After all, his main focus is number theory and algebraic geometry, and there is a big gap at the application level.

"It seems that you also live in this dormitory building?"

Su Xinghe nodded slightly and said, "I live in 512, how about you?"

"403 downstairs."

Su Xinghe was stunned for a while and said in surprise: "Isn't that the same as hemorrhoids?"

"Indeed, when we get in and out of bed, he gets in and out of me." Lu You said with a smile.

“The world is such a small place!”

Feeling that his back was getting stickier, Lu You quickly interrupted the conversation.

"I have something else to do. I'm going back to the dormitory first. We'll talk when we have time."

"Okay, walk slowly."

"You too."

Arrive in front of the dormitory door.

Lu You took out the key from his pocket and as soon as he inserted it into the keyhole, the dormitory door was opened.

A cool breeze blew against my face, dissipating some of the heat.

"Huh? Are you back?"

While speaking, Zhang Zhichuang's eyes quickly moved down and landed on the shopping bag held by Lu You, and he immediately grinned.

"I'm coming back right now. Why are you bringing gifts? You've seen so much!"

Without waiting for Lu You to reply, Zhang Zhichuang grabbed the shopping bag and turned back to the dormitory.

"Lao Gong, Lao Bi, come here quickly! Brother Lu has brought us something good!"

"Really? I'll get out of bed right now!"

"Wait for me, the BOSS is still 10% short of health!"

Lu You twitched his lips, then changed his shoes and walked into the dormitory, closing the door behind his back.

Gong Qing approached Zhang Zhichuang and urged, "Open it quickly and see what's inside."

"Don't worry, I won't be able to run away with long legs."

Zhang Zhichuang opened the bag and took out the contents one by one.

"Apples, grapes, bananas, and... what is this box? Oh, it's actually egg tarts!"

Lu You put down his schoolbag, took off his sweat-soaked T-shirt, threw it into the laundry bin, and put on a pair of dry short-sleeved clothes. He looked like he was reborn.

Gong Qing looked back at Lu You and asked, "Master, can we eat the egg tarts?"

Lu You picked up the water cup, took a sip, and replied, "Eat it! I brought it to you in the first place!"

"Thank you, foster father!"

Zhang Zhichuang couldn't wait to pick up a piece of egg tart that was still warm, and bit off half of it.

A small clicking sound sounded.

Unexpectedly, the crispy egg tart crust spread all over Zhang Zhichuang.

"Fuck! Brother Lu, you plotted against me!"

"You didn't pay attention, who's to blame?" Lu You replied calmly.

With Zhang Zhichuang's lesson learned, Gong Qing was obviously more cautious, holding the egg tart in one hand and protecting the bottom of his mouth with the other.

Lu You took out a tissue, wiped the sweat from his forehead, watched the two of them swallow the egg tarts, and then asked: "How is it? Is it delicious?"

Zhang Zhichuang stuffed the remaining half of the egg tart into his mouth and replied vaguely: "It's delicious, the skin is very crispy."

Gong Qing had a thoughtful look on his face and asked, "Master, where did you buy this egg tart?"

Lu You sat at the desk, unzipped his schoolbag, took out his computer and put it on the table, saying, "I don't have to buy it, I made it myself."

Zhang Zhichuang's eyes widened and he said in disbelief: "You can even make desserts? Are you still a human being?"

"Just mix the egg tart shell and egg tart liquid. It's not difficult. There are detailed recipes and tutorials on the Internet, just follow them."

"You won't be able to catch your girlfriend just by relying on this, right?" Gong Qing asked.

Lu You opened the computer screen, pressed the power button, and said, "No, the egg tarts are too low-end. I relied on a white chocolate chrysanthemum." "What the hell?" Zhang Zhichuang asked in confusion.

"Forget it if you don't understand."

Lu You didn't bother to explain, and adjusted himself to start studying.

At this time, Bi Yangde, who had just finished playing the game, hurriedly took off his headphones, stood up and asked, "I killed the BOSS. Where were you talking about?"

Zhang Zhichuang took off the pieces of egg tart skin bit by bit and said, "Brother Lu brought the egg tart back, do you want to eat it?"

"Egg tart? Forget it."

Biyangde sat back on the chair and said, "The calories are too high, I won't eat it."

Zhang Zhichuang frowned and said, "It's just an egg tart, is that all?"

"As for!"

Bi Yangde said with a serious face: "Maintaining a good figure requires sufficient exercise and strict diet control. Now that school has started, we can't increase the amount of exercise, so we can only start with diet."

"I really don't understand. If you can't eat this or that thing just for the sake of a good figure, what fun is there in life?"

Hearing this, Lu You interjected: "Hemorrhoids, everyone has their own lifestyle. What seems meaningless to you may just be what others like.

It's best if you understand. If you don't understand, respect it. Talking too much will only make people unhappy. "

"Too."

Zhang Zhichuang scratched his head, looked at the bright red apples on the side, and asked, "You always eat those apples, right?"

"You peel it and I'll eat it." Biyangde said with a smile.

"Can't you eat it with the skin on?"

"No."

"Depend on!"

Zhang Zhichuang left the dormitory with an apple and a fruit knife.

When he came back, the skin on the apple had been removed and divided into four pieces.

"Eat the apple."

Zhang Zhichuang walked around the dormitory, giving each person a piece of cake, and finally stopped behind Lu You, chewing on the apple while looking at the paper on his computer screen, feeling unclear.

"Brother Lu, we all have nine years of compulsory education and the same IMO gold medal. Why are you so good?"

Lu You kept his eyes on the paper and said without squinting: "It's good to be reincarnated. The genes given by your parents are incomprehensible."

"Alas! The world is so unfair!"

Zhang Zhichuang returned to his seat after finishing the apple.

"Brother Lu, the apples you bought are really good. They are crisp and sweet. I will buy a few more kilograms next time."

"Wait until next week. Buy more next week."

A few kilograms of apples cost only a few dozen yuan, which was just a drop in the bucket for Lu You's pocket money.

"Actually, I prefer the pinker texture to crispy apples."

Almost at the same time, Zhang Zhichuang and Gong Qing focused their sharp eyes on Bi Yangde, as if they wanted to pierce him.

"What, what's wrong? Why are you looking at me like this?" Biyangde trembled.

"Tell me! Where did you come from as a heretic to actually like pink apples?" Zhang Zhichuang asked sternly.

Gong Qing looked at Bi Yangde with strange eyes and said, "I don't even eat the pink apple dogs at home. They are all given as gifts. I didn't expect anyone to like them."

"It's you who don't know the goods!"

Bi Yangde snorted coldly and did not argue with the two of them. He turned to Lu You and asked, "Master, the course selection system opened yesterday. Have you chosen it?"

Lu You held his cheek with his left hand, silently calculating the formula in his mind, and said casually: "I have chosen."

"Which professional course should I choose? Experimental class or ordinary class?"

Lu You patted his head, changed his sitting posture and leaned on the back of the chair.

While thinking about the formula, I also had to deal with the questions from the three little ones in the dormitory, which was really difficult.

"If I remember correctly, it should be an experimental class."

"So are we! We can take classes together then!" Bi Yangde said happily.

"Let me tell you, I don't quite understand. What's the difference between this experimental class and the ordinary class?"

When Zhang Zhichuang was choosing courses, he simply saw the same course names, some with the suffix of "experimental class", and chose them out of curiosity.

Lu You recalled the vx conversation with Professor Xiao Liang a few days ago and explained: "Professor Xiao said that the teaching content of the experimental class and the ordinary class are the same, but the difference is the teaching method.

The experimental class is for students with good basic knowledge. Simple introductory knowledge will not be taught too much, and the teaching sequence and the depth, breadth and abstraction of the lectures will be higher. "

Zhang Zhichuang's heart skipped a beat, and he said anxiously: "What about the exam? Will the exam become more difficult?"

"I'm overthinking it. The test papers are the same. Otherwise, how would I calculate my grade points at the end of the semester?"

"That's okay!" Zhang Zhichuang breathed a sigh of relief, "I'm afraid the test papers will be doubled for me."

"No, you, who IMO have perfect scores, are still afraid of a small final exam?" Gong Qing said amusedly.

"Whether you are afraid or not is not the same thing as whether you want to do it or not. Who wants to waste effort on taking a difficult test when he can take an easy test? There is no benefit."

"makes sense."

"By the way, Master, what did you choose for physical education class? The three of us are all badminton."

Lu You recorded his scattered thoughts and replied: "Tai Chi."

Zhang Zhichuang stood up suddenly and said in shock: "Tai Chi is very popular. We are here on time, but we didn't even choose the campus network. How did you get an external network?"

"Perhaps I was lucky. When I entered the course selection website, I happened to see an open seat, and I chose it casually."

"It's probably because someone withdrew from the election and then missed it." Gong Qing guessed.

"What a waste of luck!" Zhang Zhichuang said angrily.

"By the way, why do you want to choose Tai Chi?"

Zhang Zhichuang stood with his legs apart, put on an extremely non-standard Tai Chi starting position, and said, "Don't you think it's cool to be able to do Tai Chi with one hand?"

"What about you, Great God, why did you choose Tai Chi?" Gong Qing asked.

Lu You smiled slightly and said, "Because Tai Chi is really handsome!"
