What happened?

Nothing happened, I'm just pretending to be quietly~ Eh, no, it's just a quiet lecture!

Liu Feng is still talking, after all, a good teacher must also have good students, and his classmates really give him face, and they listen so attentively one by one, well, it really gives us face!

The first time he lectured in public, he looked at the eyes full of curiosity in the classroom, and couldn't help but nod with satisfaction, good students, they are all good students, it's not in vain that we can't stop saliva......

"From the Taylor formula of the unary function, we can deduce from this to the Taylor formula of binary, ternary, and even multivariate functions, so here, there is a theorem that everyone needs to memorize. ”

Liu Feng lectured without a pause in the middle, and when he arrived here, he paused for half a second, because the first point of this class came: "Theorem 1: Let z=f(x,y) have a continuous partial derivative of the n+1 order in a certain neighborhood of the point (x0, y0)......"

Yan Shan had already changed from the relief just now to the shock now.

Yes, shocked!

Really, from childhood to adulthood for more than 40 years, she has not been as shocked as she is today!

It's like earthlings meeting aliens one day, just like suddenly one day, the scientific community declares that the earth is not round, but a flat ......

This, this, is this really their own student?

This, is this really a student who hung up 5 of the 6 classes last semester?

Is this really a college scum who only scored 20 points in the final exam?

You're teasing me!

Yan Shan couldn't understand what was going on at all, and she couldn't believe that a scumbag with a score of 20 in high mathematics could be so proficient in the knowledge points of high mathematics two!

Although he only talked about a lesson on theorems and proofs of Taylor's formula, she had never heard it from an ordinary lecturer or even a professor except for a lecturer who had been engaged in high mathematics for many years!

Because it's not just about Taylor's formula, it's about a whole set of advanced math basics!

From derivative to integral, from partial derivative to composite derivative...... It is necessary to fully grasp the previous basic knowledge in order to have such a thorough understanding of Taylor's formula!

Moreover, more importantly, this product did not turn to the book when he lectured, nor did he have a PPT, he was completely relying on memory to speak, which, this is simply ......

Yan Shan's emotions towards Liu Feng have changed from waiting to be rescued at the end, to following the rhythm involuntarily, until now the shock is overwhelming!

Freak, what a freak!

Yan Shan shook her head, it seems that she has to have a good understanding of this classmate after class.

The exterminator was shocked by Liu Feng's performance, and the students in the class threw themselves to the ground one by one in admiration.

Needless to say, the top students are immersed in Liu Feng's clear-thinking atmosphere, and they don't have time to evaluate Liu Feng more.

As for those scumbag-level classmates, no one can understand them anyway, the exterminator is too so, Liu Feng can't run away, he even took out his mobile phone one by one, and gave Liu Feng several shines.

If it weren't for the fact that the exterminator had already sat in the first row from standing on one side of the classroom to the big Malaysian golden knife, listening to the lecture with a full face of enjoyment, maybe these people would have rushed to the stage and carried Liu Feng up and down to celebrate!

Awesome, buddy! I'll give you full marks for this!

But, who's going to tell us what this thing is about?

This is the victory of the scumbag! This is the counterattack of the scumbag!

Some people even broadcast Liu Feng's lectures live and recorded the video and posted it on social platforms such as Moments, campus network, Weibo, and Tieba.

"Come and see, I see aliens!"

"On how to counterattack and ascend to heaven as a scumbag, my mother no longer has to worry about my studies!"

"Shocked, the story that the scumbag of the chemical university and the beautiful teacher have to say!"

……

A group of friends kept swiping through the circle of friends, spreading this video farther and farther.

"Damn, what class is this!"

"Are all the current freshmen so awesome?"

"666, my mother asked me what I kept looking up at, and I said someone was going to ascend to heaven......"

……

Freshmen, sophomores, juniors, seniors, and even graduate students, doctoral students, and off-campus students......

Circles of friends, campus networks, Weibo, post bars and other networks have exploded in an all-round way, discussing who this awesome buddy is, worshipping, looking up, and so on.

It's really a good thing that doesn't go out and bad things spread thousands of miles, in today's era of developed networks, a little wind and grass will spread in an instant, especially this kind of extremely eye-catching thing.

Zhou Yunshan was resting, bored and flipped out of her mobile phone to swipe the circle of friends.

I stumbled upon a video of the circle of friends, and when I saw it, it turned out to be Liu Feng, a nasty guy!

What the hell happened, even the circle of friends of their junior year of theoretical physics spread!

Surprised, Zhou Yunshan hurriedly clicked the video in.

In the picture, I saw Liu Feng standing on the podium and talking, and below was a group of serious students, especially Teacher Yan Shanyan, who was marked with a big red circle, and also listened to Liu Feng's lecture with a serious face......

probably understood the 'original situation' of the matter, Zhou Yunshan said, this guy is really in the limelight, but isn't it just a lecture on stage, what's the big deal.

But don't say it, this guy really has the demeanor of a lecturer when he talks about it on stage, Zhou Yunshan thought with a red face.

Then I saw a group of barrages: 666; What is excellent, this is; where did this guy come out; whoever has his phone, I want to give him a monkey!

What a mess!

Seeing that someone even said that they wanted to give Liu Feng a monkey, Zhou Yunshan threw away the phone angrily, still in the draft book.

What a shame!

……

Brother Feng of the society, has become a legend since then.

Liu Feng didn't know that now he has become popular on the Internet, especially on the social network of Huada!

Even if people don't know his name, they have seen his face.

However, even if he knows, I'm afraid he won't care, after all, as a 'college bully', you must have the consciousness of a college bully, isn't it just to become famous, there will be more moments to become famous in the future, what's the big deal!

Sun Xiaoxiao looked at Liu Feng, who was calm and scolding Fang Xuan on the stage, while comparing the textbook, while listening, her eyes were full of little stars, she turned her head and accidentally glanced at Zhuo Tingting next to her, but found that this product also looked like a Confucian person, her eyes were full of traces of someone Liu, where was there a trace of a gentle saint, she was completely a little girl!

, Tingting has taken a fancy to someone!

No, I can't let my Tingting fall into the clutches of the devil!Sun Xiaoxiao's mind instantly crossed this thought, after all, Zhuo Tingting's appearance is so likable, even girls!

"Hey, hey, Tingting......"

"The second part, the proof of the extreme sufficiency condition......" Liu Feng became more and more comfortable on the stage, more and more comfortable, talking spittle, raised his eyes and suddenly saw Sun Xiaoxiao's small movements, and suddenly became unhappy, there are still students who don't listen well to the lectures and make small movements, and disturb others, it's really unbearable, "The girl on the left of the third row, listen carefully in class, don't affect others' ......"

Suddenly, a group of people followed Liu Feng's line of sight, their faces angry.

Teacher Liu said so well, there are still people deserting!

"What?" Sun Xiaoxiao was stunned, only to feel that there was a large group of grass ~ mud ~ horses galloping over her head, what did I do to anger people, as for looking at me with the eyes of the enemy?

Especially the exterminator's gaze, tsk, it's too scary!

Therefore, Sun Xiaoxiao, who was deeply hurt, instantly changed his attitude towards Liu Feng from worship to resentment......
