"I've already talked about the formula, so I'm going to come up with a problem to see how well you can get it: let it be for any smooth directed closed surface S......"

Professor Lu explained the topic clearly, and then swept his gaze to the students.

Everyone lowered their heads, for fear of being suddenly named, this kind of casual question, if you don't answer it well, you will deduct class points!

Seeing the black pressure on the top of his head, Professor Lu felt a little uncomfortable, even in Yan University, there were fewer children who really learned......

"Professor Lu."

Promise, who was sitting in the first row, suddenly stood up.

"Promise classmate, you will answer this question?" Professor Lu was quite impressed by this excellent female student.

"Professor, I want to recommend Nan Sheng, she once said that she is good at points."

The promise lightly hooked the corners of his mouth, and a trace of cunning crossed his eyes.

"Oh? Then please answer the questions of Nan Sheng. ”

Although Professor Lu was not familiar with the name, he still listened to the promised suggestion.

Students from other schools didn't know Nan Sheng, so they looked around and searched for Nan Sheng.

Nan Sheng stood up from the last row, without a trace of panic on his face, he was made a fool of himself in his previous life because of this question, but this life is different......

She smiled calmly and replied in an unhurried tone: "This problem should be solved by the Gaussian formula, according to the Gaussian formula, the surface of the curve is constant zero......"

Nan Sheng said for two minutes, analyzing this complex operation into a way.

And Professor Lu was even more surprised, originally when this student stood up from the last row, he had a preconceived idea that she couldn't do it, but she was able to answer the curve integral question so completely, which surprised him!

And this kind of calm bearing can simply compete with the doctoral students he brings.

The old man smoothed his gray hair with his hand and said, "Very good answer! Add two points to you, what is the student number? ”

After Nan Sheng reported his student number, the old man lowered his head and looked for it on the roll call.

The other students all looked at Nan Sheng, and their eyes changed from doubt to shock and admiration! This is simply a study of God!

But there was only one look that was different from the others—the look of Promise was cold and vicious, like a poisonous snake.

She glared at Nan Sheng, and her heart was so angry that she almost crushed a mouthful of silver teeth.

"Damn it!" Promise a resentful stomping.

I'm here to make her make a fool of myself!

But now, not only the professor praised her, but even those classmates were impressed with her!

Xu Yu looked behind him again, and this time he met Nan Sheng's eyes, Nan Sheng smiled at her, and said with his mouth: Thank you for digging the pit for me.

Xu Promise was almost so angry that he vomited blood, and quickly turned away and stopped looking at her.

Nan Sheng raised his eyebrows indifferently, and became more confident in the future academic evaluation, and Yu Guang saw Yu Yu looking at him.

After hesitating for a long time, she finally said in a voice as loud as a mosquito: "Nansheng, I'm not because of those things...... Don't get me wrong. ”

Nan Sheng was stunned for a moment, and then understood what she meant.

"It's okay, it's okay if you can ignore me, I don't have any friends in this class, isn't it miserable?"

Nan Sheng's mischievous tone made Yu Yu laugh, and she nodded obediently like a shy little rabbit.

"Wait for the lights to go on—"

When the bell rang for the end of class, all the students scattered.

Only Yu Yu slowly packed up her things.
