Everyone stared at Zhao Xuan's straight and tall back, he put one hand in his pocket and the other hand held chalk, writing the blackboard.

The sound of chalk rubbing against the blackboard echoed through the quiet classroom.

The tip of the pen is like a shadow, jumping on the blackboard, Zhao Xuan's movements are not stagnant, like flowing water, almost in one go!

For a full ten minutes, the huge blackboard was already filled with dense formulas, numbers, and some text explanations, and the flowing handwriting was not cluttered in the slightest.

From beginning to end, he never rested, which shows that his arm strength is extraordinary.

Looking back, everyone saw a faint but casual smile on his face, and after doing all this, he was at ease!

"This guy really has arrogant capital...... someone was stunned and shocked.

Some people pouted, not confident: "Is it right or wrong or is it another matter." ”

"Look at the teacher's expression, I'm sure I've passed the test. Someone sighed.

At this time, the middle-aged Mediterranean, staring at the calculations on the blackboard, his face was full of disbelief, and his body was trembling slightly, "God...... Genius?"

He said that as long as Zhao Xuan completed one-tenth of the calculation, it would be considered a victory.

But the calculation on the blackboard, not to mention one-tenth, has exceeded one-fifth!

This question, which combines the knowledge of mathematics, economics, big data, operations research and other aspects, is a very comprehensive problem, and the countless formulas alone can make people dizzy.

To solve it, you need a huge and complex knowledge base, as well as super computing power.

Even for him, it took a whole day and night to completely solve this problem.

For an average professor, it is estimated that he will give up halfway through the solution.

But the young man in front of him only spent about ten minutes to solve one-fifth of it, and the whole process was extremely easy!

What is this concept?

How many times stronger is he than himself?

"The result is already obvious, teacher, will you announce it?" Zhao Xuan smiled faintly and looked at Song Moxin, with pride, as if to say:

Brother is not awesome, did you like me?

Of course, Song Moxin didn't like him, she only felt a strong disgust.

She doesn't deny that he is a capable person, but he has a problem with his character, it is not right to be late, and he has no respect for his superiors, and he is even more public ** her.

Extremely arrogant and morally corrupt, he is a scumbag, and it will only make people disgusting!

"The villain has ...... ambitions," Song Moxin sighed helplessly.

The middle-aged Mediterranean also sighed, and said weakly: "I won't care about you anymore, you won't ...... win"

"He didn't win. ”

At this moment, Ling Yu said lightly, "Teacher, you didn't lose. ”

"What?" the crowd was confused.

The middle-aged Mediterranean was also puzzled: "I promise that if he can complete one-tenth of the calculation, even if he wins, he will complete more than two-tenths......"

"He's said that, what else do you want?" Zhao Xuan looked at Ling Yu and seemed to be smiling.

"That's in the right situation, he's wrong, so the progress is ...... Zero. Ling Yu spoke calmly as if he hadn't seen anything.

"Zero, don't be funny......" Zhao Xuan shook his head in disdain.

The middle-aged Mediterranean scratched his head and said, "I've checked, and there doesn't seem to be any problem with his way of calculating......"

Ling Yu actually didn't need to care, how Zhao Xuan pretended to be forced, as long as he didn't step on his head, it didn't matter.

However, he knows that little Lori's mind is above ordinary people, and although she doesn't understand those things on the blackboard now, her future perception will be somewhat misleading, and he needs to correct it.

Besides, the middle-aged Mediterranean is a good teacher, and he has thought about him, and it is not impossible for him to take less unjust paths.

The substitution of the third formula in the lower left corner and the conversion of the fifth formula in the upper right corner contradict each other. The estimation assumptions are not valid, and all the estimation results are invalid, and the progress is zero. ”

The flat voice, the casual tone, Ling Yu glanced at it, pointed out this, and then didn't pay much attention to it, leaving only the middle-aged Mediterranean and Zhao Xuan stunned in place, as if struck by lightning!

It was as if they saw a high-rise building made of data, and a crack spread somewhere in the foundation, and the crack was rapidly dispersed, and in an instant it was dense like a spider web, covering the entire foundation.

With a bang, the foundation collapsed, and the entire building collapsed!

Just like the domino effect, if the first piece falls, it will overwhelm the second piece, and the next thousands of pieces will not be able to escape the fate of falling.

A blackboard of calculations may seem complex and numerous, but it only takes the most basic and inconspicuous contradiction to destroy everything!

The middle-aged Mediterranean had long forgotten about the gambling contract, and he was so excited that he couldn't speak, and immediately trembled and picked up a pen and paper to write it down.

Zhao Xuan looked at Ling Yu in shock, feeling incredible.

There are hundreds of formulas densely packed on the blackboard, and dense phobia is going to make a mistake, but Ling Yu pointed out at a glance that strong eyesight is essential, and his terrifying mental arithmetic ability is even more terrifying!

This person is really powerful!

Zhao Xuan's eyes had a strong and solemn color.

Everyone at the bottom blinked, unaware.

Little Lori didn't care about thirty-seven twenty-one, and organized a few acquaintances to shout "666" for Baba.

Excellent man, always fascinating.

Only then did Song Moxin realize that her understanding of Ling Yu was too little and too little, she simply didn't know anything!

She couldn't tell what it was like in her heart right now, but the feeling of remorse and heartache became more and more obvious.

"By the way, the bet was won by the teacher, so that classmate, you should fulfill your promise, right?"

Suddenly, someone spoke, looking at Zhao Xuan playfully.

Zhao Xuan looked at the man fiercely, his cold gaze was like a blade, and he directly made the person lower his head.

"Kneel down and apologize, it's you who said it yourself!"

"That's right, kneel! Talk like a fart, what kind of man!"

“......”

But then, more people shouted in unison, and they were happy to embarrass such arrogant and immoral people!

Zhao Xuan didn't speak, and his face became more and more gloomy.

At this moment, the middle-aged Mediterranean put down the pen and paper and sighed, "I don't need the student to kowtow to me, just apologize." ”
