After hearing his student's words, the professor couldn't help frowning, and was about to open his mouth to stop it, but found that Xu Mang had already picked up the pen and was ready to do something about the topic.

"What are you doing here?" the professor asked hurriedly.

"Do the question!" Xu Mang was stunned for a moment: "He asked me to do it." ”

“...”

"I'm kidding you!" said the professor with a black face, "Don't mess with me, you kid!"

"Oh..."

Xu Mang put down the pen in his hand in embarrassment, and said helplessly: "But this difficulty is really not good... It's not enough to let go of yourself, and we need to make it more difficult. ”

“？？？”

“？？？”

At this point,

The two students present looked confused, who is this guy?

How do you have such a good relationship with the professor, and... The professor doesn't seem to have a way to take this guy.

It's kind of awesome,

If a student can reach this point, I'm afraid it's not as simple as a top student.

It should be a top student with a background...

"Xu Mang!"

"You can't measure others by your standards. The professor said solemnly: "If you use your standard to make the questions, it will basically be a zero score." ”

Belch?

Xu Mang?

The professor said he was Xu Mang?

The two students looked a little surprised, they had heard of the name Xu Mang.

"Xu Mang?"

"The legendary Xu Mang is you?" another student looked at Xu Mang and asked curiously, "I've read your paper, it's really a bit awesome!"

"That's nature!"

"After all, I'm the spokesperson of the awesome. Xu Mang was not modest, and said with a smile: "I was born awesome!"

“...”

“...”

“...”

Others say things like this,

It's funny to listen to, because it's a joke in itself.

But Xu Mang...

It makes me feel angry when I listen to it!

Because he is telling the truth.

"Xu Mang... Almost. The professor reluctantly said, "You can go back." ”

"Don't!"

"I'm here to guide the work, professor... Just let me guide you, and it just so happens that your students are too. Xu Mang moved a crooked brain, and said with a smile: "I'll come up with a random question, this topic is my latest understanding, and the difficulty is basically close to the international competition, do you want to experience the real difficulty?"

The coach thought for a moment, looked at his student, and asked, "What do you think?"

In fact

These two students really wanted to challenge Xu Mang's problem, especially when they heard that it was an international competition-level question, and their desire to challenge was even stronger.

"Good!"

"I can too. ”

After receiving a response, the professor said to Xu Mang, "Then let's try it." ”

moment

Xu Mang took a blank piece of paper and began to give a proposition to the two challengers.

Let P=A1A2... Ak is a convex polygon on a plane with vertices A1A2... , the abscissa of Ak is an integer, and all are on a circle, the area of P is denoted as S, let n be a positive odd number, and the square of the length of each side satisfying P is an integer by n integers.

Proof: 2S is an integer and is divisible by n.

Finish!

Xu Mang raised his head with a smile, and then saw the cute appearance of the two, like his past self.

"Let's get started?"

"Give you two hours of time. Xu Mang said: "There should be no problem, this is a topic for high school students." ”

“...”

“...”

Is this a high school student topic?

Beat to death do you believe it or not?

The two looked at Xu Mang, who was smiling, and was instantly filled with helpless anger.

As a top student of the Department of Mathematics of Jiangxi University, I didn't know how to face this problem for a while.

Two hours...

But yes, it's just that it's possible... If the idea is wrong, it won't be solved in two hours.

At this point,

After the professor glanced at Xu Mang's question, he asked Xu Mang, "Xu Mang, are all your questions so inhumane?"

Xu Mang: Embarrassed

What does it mean to be inhuman?

How is there no humanity?

At a glance, this topic is full of love for the contestants!

This difficulty, this creativity, this thinking, it's all love!

ultimately

These two students from the Department of Mathematics of Jiang University did not do Xu Mang's non-human problems, of course, they can do it, but it takes a lot of time, and the current Zhejiang Provincial Mathematics Olympiad is very tight, so they gave up.

And Xu Mang...

He achieved his goal.

Appropriateness has been added to the challenge by adding some difficulty.

"Is it appropriate?" a student asked curiously, "Xu Mang... Isn't it going to be too hard?"

"It's not difficult!"

"Do you think it's difficult?" asked Xu Mang.

"Difficult... It's not that hard, but don't forget, it's a group of high school students!" the student said, "You're already talking about college. ”

Xu Mang nodded, and said silently: "These players are the elite of Zhejiang Province, can't they be described as geniuses, right? Since they are so-called geniuses, there is no problem, because with the knowledge points of high school, it is completely solved, but it is a little troublesome." ”

This student agrees with Xu Mang's point of view, although it involves university knowledge and can use high school knowledge to solve problems, there is no problem, but in the process and verification, it will be a little cumbersome.

Long

Xu Mang was almost familiar with these two students, and at this time he knew that the two were juniors, one was named Qu Wenzhong and the other was Ni Jiawei.

End at noon,

The three of them went to the cafeteria together.

"Huh?"

"You didn't take the postgraduate entrance examination?" Xu Mang was stunned for a moment, and asked in surprise: "Why don't you take the postgraduate examination?"

"There are thousands of paths in life, and there is not only one for graduate school entrance examinations. Qu Wenzhong said: "I signed a contract with a securities company a year ago, and I went to work in their company after graduating from university, with a starting salary of 15,000 a month. ”

“...”

"What about you? Xu Mang asked.

Ni Jiawei said: "I'm pretty much the same, but I'm not in a financial company, I'm in a high-tech company, and I signed the contract a year ago. ”

"Oh..."

Xu Mang nodded: "It's also good, the postgraduate entrance examination is just to give yourself one more direction to choose in your life, since you have a choice now, it is reasonable to give up what you should give up." ”

"Xu Mang?"

"What are you going to do in the future?" Qu Wenzhong asked.

"Me?"

"Scientific research and education. Xu Mang said: "Enhance the country's scientific research capacity and improve the social and educational environment!"

If this was said by someone else, the two felt that this person was a bit vain, but if it was said by Xu Mang, then there would be no problem.

That's exactly what he's doing.

"That's right. ”

"In the future, if you are not satisfied with your work, you can consider Yanghong Group. Xu Mang said: "Half of the industries under Yanghong Group are involved in high-tech, and there is a shortage of talents like you. ”

Yang Hong Group?

The two were stunned for a moment, not to mention... I did think about it.

But

Someone else took the lead in sending out the invitation.

"Xu Mang?"

"What is your relationship with this Yang Hong Group?" Qu Wenzhong asked, "You are the legendary eldest young master?"

"Uncle. ”

"The eldest lady of Yang Hong Group is my girlfriend, the kind who is about to get engaged..."Xu Mang said this, a sad expression appeared on his face: "She is an extremely savage woman. ”

“...”

“...”

What's the situation?

The atmosphere suddenly became sad.

Is it so scary?

"Xu Mang?"

"Since you live in such pain, why don't you choose to break up?" Ni Jiawei asked: "Isn't there no pain in breaking up?" ”

"Cut!"

"We are true love!" Xu Mang suddenly became noble and said to the two: "You don't have a girlfriend, so you don't understand." ”

Qu Wenzhong: (艹艹) Convex

Ni Jiawei: (艹) Convex

Afternoon

Xu Mang returned to his temporary office and began a leisurely life.

That's the question

Anyway, there's still a week, so what's the panic.

"If you have a topic, humming a little song, eating hot pot..."Xu Mang began to fantasize about the unrealistic scene: "How good it would be." ”

Then

The phone rang suddenly, and I glanced at Xiao Man's.

"What's wrong?" asked Xu Mang.

"When are you coming back?" asked Yang Xiaoman.

"Uh..."

"Ten more days. Xu Mang said: "There must be a beginning and an end." ”

"Oh... By the way, Dad asked me... Do you have a scientific research project that is short of money?" Yang Xiaoman said: "The second grandfather told my father, it is best to discuss it with my father when you come back." ”

What the?

Got it?

It's good... Save the opening.

"Okay, wait until I'll get back. Xu Mang said, "I'll hang up first?"

"Wait, kiss!"

"Doot toot!"

Yang Xiaoman's request was ruthlessly strangled in the cradle by Xu Mang.

Kiss?

Not dear!

You have the ability to hit me through your phone!

However, Xu Mang didn't know that Yang Xiaoman at this time recorded the reason and number of times he died in the 'death notebook'.

...

Six days later,

There are still two days left before the Zhejiang Provincial Mathematics Olympiad, Xu Mang has completed all the tasks, but he has not handed them over to Mr. Teng for review, Xu Mang's plan is to hand them in on the last day.

Turn on the system,

Xu Mang glanced at his chemistry skills, the chemistry skills he had accumulated during this time had reached more than 50,000, and it was time to hang up his knowledge points.

Inorganic chemistry, hang on!

Organic Chemistry, Hang Up!

Polymer chemistry, hang on!

Analytical Chemistry, Hang Up!

"Huh?"

"Why do you still need biological skills?" Xu Mang was a little confused, he found that there are many marginal and interdisciplinary disciplines in chemistry, atmospheric chemistry, environmental chemistry, marine chemistry... These knowledge points require dual skills.

At last

Xu Mang chose physical chemistry and cosmochemistry.

After looking at the time it takes for these knowledge points to be fully understood, it is estimated that it will take a month and a half.

Syllable!

The office door was opened.

Xu Mang saw Teacher Teng walk in with an indifferent face, and then... His face changed slightly, and Yin Tang turned a little dark.

"Put your feet down!"

"What does it look like?" Mr. Teng said helplessly, "How is the question?"

"It's okay. ”

"It's almost time to wrap up. Xu Mang said with a sincere face: "Teacher Teng... Do I get paid?"

“...”

"Nope. Teacher Teng shook his head: "To make a little contribution to the cause of scientific research and education, must it be linked to money?"

I...

This...

Mr. Teng's hat wearing technique is also very high-end!

"Teacher Liang?"

"What are you looking for me?" asked Xu Mang curiously.

"I came over to ask about the progress. Teacher Teng said solemnly: "Speed up, those players will come tomorrow." ”

"That's right!"

"Remember to be a kind person tomorrow!"
