After Zhang Yuan finished the whole answer, Wang Lili just opened her mouth and swallowed the originally prepared speech.

She secretly rolled her eyes and replied, "This classmate...... That's a good answer, please sit down. ”

It turned out to be the legendary god of learning, this kind of person is actually the most annoying, if you don't study, you will, and you will bring a bad classroom atmosphere.

Ye Kaifu had already regained the admiration in his heart, and he was no longer surprised, as if he was numb.

"The great god is really a great god, and he will not change the essence of the strong because he sleeps......"

The strong are qualified to sleep.

He was ashamed of his jealousy.

The next thing was fine, Zhang Yuan no longer dozed off, but just took care of himself, and the focus of his pupils seemed to be in the distant void.

The teacher didn't take another roll call, anyway, he read it like a sutra in a class, and then it was over.

"Jingle bell", the bell rang.

Wang Lili assigned a few after-class exercises and signaled that everyone could leave.

When they left, everyone was very positive, which was really frustrating.

"Let's go, let's go back too."

After sleeping for a while, Zhang Yuan was in good spirits and wanted to go back to the bedroom to continue his liver dissertation.

Ye Kaifu reluctantly sorted out the information and asked Zhang Yuan: "Mathematical equations are too difficult, is there a general framework for easy understanding?" ”

Zhang Yuan thought for a moment and said, "Framework? You're talking about the solution idea, right? There is actually not much complexity in this course. ”

"Solving homogeneous partial differential equations is the simplest, as long as you use the separation variables, you can solve them in four steps......"

"Then to solve the problem of non-homogeneous generalized definite equations, either by introducing a new function, or by using a method similar to parametric variation, the non-homogeneous problem is solved as a homogeneous problem, and then the Fourier series can be developed to form a new solution condition......"

"Later, the non-homogeneous boundary conditions are transformed into homogeneous boundary conditions, and thus transformed into the problem of solving non-homogeneous generalized equations......"

"Stop!"

Ye Kaifu wanted to cry without tears, and couldn't help screaming.

When he found that there was no shortcut in the whole learning process, he could only say a sentence silently in his heart:

Terrible!

……

After packing their things, the two prepared to leave.

"Zhang Yuan, don't go yet!"

At this time, Zhang Yuan suddenly heard a female voice calling behind him, and turned his head to see that it was Xu Yunjing, a graduate student led by Professor Wang Zhong.

"Senior sister, are you also here to attend the class?"

Xu Yunjing said: "Yes...... I plan to switch to mechanical engineering when I am studying for a doctorate, so I will learn a little relevant knowledge first, and it will be convenient to change majors later. ”

Zhang Yuan was curious: "Changing to engineering? You're studying math now, right? Won't Professor Wang be angry? ”

"No, no, no...... He should respect my opinion. ”

Xu Yunjing thought to herself: I'm not that kind of genius student, why do I have to take the hard road of pure numbers, I can't make money and work hard, can't I get along with myself?

“…… He's your ...... Bro? That's a strange name. Another pair of big dripping eyes also looked over, it was substitute teacher Wang Lili.

"yes, I'll introduce you." Xu Yunjing said with a smile: "Her name is Wang Lili, she is a good friend of mine, and she is now studying for a master's degree with Professor Lin from the School of Mechanical Engineering. ”

"Hello senior sister!"

"This junior brother is quite shy. I deserted in class, slept, and was caught by me. Wang Lili said with a smile.

Her voice lowered slightly: "Although that question was killed by him in seconds." ”

Zhang Yuanpo was a little embarrassed: "Senior sister, I'm really sorry, I'm tired from writing papers, so I accidentally fell asleep." I didn't mean to. ”

"I'm going to write a thesis at such a young age, in what direction?"

"Analyzing Robot Motion ...... with Geometric Group Theory and Topology"

As soon as she heard the title, Wang Lili was a little speechless: "Are all the children so perverted now?" What kind of group theory, topology, I'm still worried about sending paper, three districts and four districts are good. ”

Seeing that they were greeting each other, and in the blink of an eye, they became senior sisters, junior brothers or something, Ye Kaifu, who was standing on the side, rolled his eyes, and lost his interest in being a light bulb.

He greeted angrily: "Zhang Yuan, I'm going to the library, bye!" ”

"Bye-bye!"

Ye Kaifu turned around in a chic manner, with a smile on his face, and in his heart, what "people live to learn" must be a lie.

Such a good-looking senior sister hooked up in a blink of an eye. This kind of technology is simply a model for my generation.

Since Zhang Yuan is picking up girls, let's also pick up girls, maybe we can meet one in the library?

The holidays are running out, and we can't afford to be forced like this anymore.

……

After chatting like this for a while, Zhang Yuan asked, "Senior sister, what are you looking for me?" ”

Xu Yunjing patted her head: "I almost forgot, there's really something." ”

At this time, there were only three of them in the entire classroom, and Xu Yunjing rummaged through her small bag.

She took out an invitation letter and handed it to Zhang Yuan: "In another week, the auditorium of Xisha University will hold the award ceremony of the 'Galaxy Award' to commemorate the successful construction of the Earth Era. ”

Awards?

Zhang Yuan was full of excitement, and he didn't seem to have done anything. The paper hasn't been written yet, and he's just an ordinary spaceship worker, what award do you get? Why?

"How can it be my turn?"

"It's your father's award, the beauty you want!"

"Oh!"

Zhang Yuan's heart jumped, and his father's award seemed to have no right to refuse.

Xu Yunjing made an exaggerated gesture: "That's the legendary first prize of the Galaxy Award, with a prize of 10 million!" As your father's only immediate family, wouldn't it be too much for you to lead an award on his behalf? ”

"The Earth Age is about to depart, and all these face projects have to be done. And there will be a fundraising ceremony behind it, and it is the most important thing to mobilize those local tyrants to donate. ”

"The foundation is short of money, not hundreds of millions, but hundreds of billions, trillions! It's also good to go to that group of entrepreneurs and pick up some wool. ”

"Okay, okay, I got it."

However, it can't be said to be a face project, it's an honor that my father deserves!

Zhang Yuan thought about it, he had already donated all his belongings, and he didn't have any psychological burden, so he just went.

He asked, "Shall I speak or something?" ”

Xu Yunjing said with a smile: "It's good to come on stage to receive an award." Who will pay attention to you, a primary school student, look at your stinky beauty! You are not a party to the party, just a representative, and the reporter will not embarrass you. ”

"It is possible for you to say a few words of 'thanks', thank the government, thank the foundation, thank the jury, etc., it's very simple, you don't have to worry about the donation activities later, we will take care of it."

"That's good." Zhang Yuan hated that kind of troublesome ritual the most. If you publish a long article, you have to write an article, and it is better to have this time than a liver paper.

"Don't forget, I'll let you know when the time comes."

"Got it, got it."

After chatting about this, Zhang Yuan said goodbye to the two giggling sisters, wanted to tease his senior sister, and went to think about the paper alone.
