Please let go, I am not your boyfriend

Is this a human thing?

Lu Xun once said that time, like a wild donkey that has run free, slipped through the crack of the door with a slam.

When Lu Li opened his sleepy eyes, glanced at his phone, and realized that it was Friday, he couldn’t help but sigh that what Mr. Lu Xun said was really right.

It has been two days since he drove back from Jiangling.

For the past two days, he almost ate and slept. He didn’t even want to turn on the computer.

He swore that he would never drive for such a long time again.

Really too tired.

If he hadn’t been woken up by the phone call, he still wanted to go back to sleep.

He glanced at the number of the missed call, it was his roommate.

“What’s the matter?” He asked after retorting.

“Brother Lu, the math teacher has been calling names for four days in a row. In these three days, you are the only one who didn’t go. He said it yesterday, and he still called names today. If you don’t come today, he will report it. The school missed it.” The voice on the other end of the phone was a little anxious.

Lu Li: “Can you help me answer it?”

“I can’t answer, Brother Lu. Yesterday and the day before yesterday, he called those who hadn’t been there before, and all those who hadn’t been there were called to the podium to look at the photos of the students one by one. If you can answer, I’ll help you You answered.”

Lu Li: “…All right, I understand.”

After hanging up the phone, Lu Li fell into deep thought.

I’m a billionaire now, and I still have a system, should I go or not?

After thinking for a while, he still decided to go.

After all, let’s put it this way, I am still a student now.

Moreover, to be honest, Tianjing University’s school rules are quite strict. If such a thing is really found out, it will be recorded as a major demerit, or it will be dropped out of school.

To be honest, Lu Li couldn’t think of what he would do if he was expelled from school.

Renting a boyfriend for the day?

Come on, the two clients, Nan Jinping and Lin Xiaowan, almost drove him crazy.

Forget it, let’s go.

Lu Li reluctantly got up from the bed, wiped his face briefly, put on some clothes, and ran to the classroom.

Soon after.

The class bell rang.

Looking at the full seats in the classroom, the teacher on the podium nodded in satisfaction, “That’s right, this is what you should do. It’s not right for you to skip class when you are only a sophomore. Okay, now open the textbook , let’s talk about Fourier series, first, let’s review the last lesson…”

Land from:…

Didn’t they say roll call!

Why don’t you order it!

Fuck me?

Forget it, I didn’t come to class just for roll call. Although I don’t understand, let’s listen.

But, listening to it, Lu Li felt something was wrong.

Those mathematical formulas that are like heavenly scriptures, and the formulas and theorems that he knows every word but can’t comprehend the meaning when put together, have become extremely simple at this moment?

Oh, so the Fourier series is derived in this way?

Does this look quite simple?

Is this the difference between Fourier series and Taylor’s formula?

Can the Fourier series be used like this?

It’s interesting…

While Lu Li was listening, the pen in his hand was scratching on the paper, and at the same time he couldn’t stop nodding.

The person sitting next to him looked at Lu Li, feeling very speechless.

They are all sitting in the last row, what are they pretending to be?

Who doesn’t know who?

Who are you nodding in this void?

cut.

The man snorted disdainfully, and then continued to look down at the mobile phone in the book.

“Do you understand this sample question?” The teacher on the podium put down the chalk and looked at the students.

The students in the first and second rows nodded wildly.

The students in the third to fifth rows froze for a moment, then nodded.

The students in the fifth row to the eleventh row had bitter faces, but looked at the people in front of them and nodded. In the end, they could only nod.

The students at the back of the eleventh row raised their heads as if they had just woken up from a dream, then they nodded at the people in front of them, and followed suit mechanically.

“Understand, right? Well, I’ll choose a classmate to answer the next practice question.” The teacher nodded in satisfaction, and then opened the roster.

Except for the students in the first row and the second row, everyone buried their heads deeply in their books, for fear that they would become that unlucky guy.

“I’ll look for it,” the teacher flipped through the roster and said casually, “Student Lu Li, please come up and answer this question.”

He just said that casually.

Because, he didn’t want to waste his time doing roll call for that student named Lu Li.

So, he just said it casually.

He had decided that Lu Li would not come, so he continued to look through the roster.

However, just when he was about to open his mouth to continue picking the next student, a voice suddenly appeared in the classroom, “Here”.

The teacher suddenly raised his head and found that a boy sitting in the last row actually stood up?

Lu Li is here?

The teacher couldn’t believe it.

Also unbelievable is Nan Jinping.

She was too familiar with this voice.

That was the voice that haunted her dreams.

she turned back abruptlyThen, she saw the figure that was firmly imprinted in her heart.

Tears suddenly flickered in her eyes.

“I found you…” she murmured, and then, remembering something, she suddenly buried her head in the textbook.

She was afraid that if Lu Li saw him, he would run away again.

So, she decided to go directly to block him during the small class break!

The teacher looked at Lu Li who came up to the stage, and didn’t say much, just nodded and handed him the chalk.

As a teacher, he would never speak out to ridicule Lu Li in such a large audience.

He is professional, and he will never do something that hurts the self-esteem of students.

It’s just that he was a little curious.

Because, when Lu Li took the chalk in his hand, his expression was extremely indifferent.

It was a kind of indifference with a well-thought-out plan.

“Could it be that this student really knows how to do it?” The teacher muttered in his heart.

He saw the scene just now clearly. Fourier series is a very difficult thing in the first place.

What’s more, this Lu Li was sitting in the last row.

Moreover, judging from his aura, he is obviously the kind of rich second generation with high self-cultivation.

Isn’t this kind of rich second generation usually gold-plated?

The teacher looked at the blackboard with puzzled eyes.

The more I looked, the more frightened I became.

Because, Lu Li actually started writing on the blackboard like flowing clouds and flowing water!

Moreover, this is not counted.

At the beginning, he did use the same method as the sample question.

But, halfway through writing, he started to change.

He actually didn’t follow the most basic and general method among the examples, but also the most computationally intensive method.

Instead, after proving that Lebesgue is integrable, McLaughlin’s undetermined coefficient method was introduced, and finally, the Cauchy formula was used to solve this problem!

The teacher was completely dumbfounded.

Among these contents, even the simplest Cauchy integral formula and McLaughlin’s undetermined coefficient method are only involved in the “Mathematical Analysis” course for mathematics majors, and they are a headache for countless people.

Not to mention that this student even proved the Lebesgue integrability of this question!

Is this meow really a sophomore? ? ?

Which university’s mathematics professors are his parents? ! !

No wonder, no wonder I had to come to my class.

There is no need for people to come to class!

“Teacher, I’m done.” Lu Li put the chalk on the podium and turned to look at the teacher.

“Well, Lu Li, right?” The teacher thought about it.

“Well, I’m sorry teacher, I have something to do this week, so I didn’t come to your class, I…”

The teacher raised his hand and interrupted Lu Li, “I can understand, but try to come to my class as much as possible, otherwise people will think you have something against me. If you have something to do in the future, please ask someone to tell me … Forget it, no need, come to my class from now on if you have time, if you don’t have time, forget it, just do your work.”

Land from:…? ?

Students in the audience:? ? ? ? ? ?

Is this still their old-fashioned teacher? ? ?

What does this mean? ? ?

Tell a student, if you don’t have time, you won’t use my class? ? ?

What the hell? ?

Besides, what does it mean that if Lu Li doesn’t come to his class, it will make others think they have a problem with him? ?

Also, what is written on the blackboard? ? ? ? ?

Is this really something that humans can write?

Is this what people do? ?
