"What did you just say?" The cousin looked at her husband, and an incredible expression appeared on her face: "Quickly recount all what you just said to me, and tell me every word!"

"Huh?"

"It's... It's very difficult. The cousin-in-law said helplessly: "Anyway, it's the mistake you just pointed out, Xiao Xu had already pointed it out for me two hours ago, and neither of us took it to heart at that time, until... Just now. ”

I...

This...

How is that possible?!

Xiao Man's fiancé, Xiao Xu, turned out... Is it true that the talent for mathematics is so high?

If what her husband said was not a lie, then Xiao Xu would probably have solved the problem he came up with in the afternoon, perhaps for some reason, he didn't want to spend too much time on that topic.

Cousin Xiao Man is very helpless, in case his own idea is true, this Xiao Xu is simply terrible,

Before that, I had read a lot of Xiao Xu's papers, although there was a lot of mathematics involved, but at the time I thought that there was someone in the team who specialized in solving mathematical problems, but now it seems that it is Xiao Xu who solves mathematical problems.

"You didn't lie to me, did you?" asked Cousin Xiaoman.

"Nope!"

"At that time, I gave a lecture to Xiao Xu, and he sat next to me, listening attentively, and after I finished speaking, he pointed out my mistakes on the spot, and then you appeared, and then the rest of the thing happened. The cousin-in-law said, "As time goes on, I am talking to you now. ”

“...”

Cousin Xiaoman has long been accustomed to her husband's narrative, and at this time her self-esteem has been hurt, and the victim turned out to be her cousin's fiancé, a mathematics professor at Cousin University, who lost to a physics professor at Fuda, or in the field of mathematics.

It's not that I belittle Fuda, it's just that I lost to amateurs in my professional field.

"How many times have you spoken?" asked my cousin hurriedly.

"Again!"

"Are you sure it's once?" said my cousin incredulously, "Not three times?"

"Just once. The cousin-in-law said seriously: "I will never lie to people about this." ”

Again...

My heart hurts!

As a professional math professor, I read it carefully twice before I found the error.

At this point,

When my cousin-in-law saw his wife, he was shocked from the beginning to the current dissatisfaction, and asked cautiously, "Wife... There's something wrong with your expression, are you on the same page as someone else's Xiao Xu? I find that I'm not as good as someone else's Xiao Xu, don't be like this... People are guests. ”

originally

There is nothing big about it, but he was so angry by his husband that he was angry, and he said angrily: "He is a physics person who wants to defeat me in the field of mathematics? You are also highly educated, do you think it is in line with science?"

"It's not..."

"I'm just a doctor, so I won't be involved in the battle between your professors. The cousin-in-law said helplessly: "I am innocent... You can do whatever you like, anyway, don't hurt the harmony when the time comes, after all, they are all relatives. ”

"I know!"

"You sleep your sleep. The cousin glared at her husband and sat silently on the bed thinking about something.

...

Following

Xu Mang and Xiao Man were holding on to death, there was no way... Both of them suffer from a terminal illness 'if you don't hold each other will die syndrome', as long as the two of them lie in bed together, they must hold each other, otherwise it will be difficult to sleep, of course, it doesn't matter when you are alone.

Suddenly, the door was opened, and a dark shadow rushed in, this black shadow turned on the light, and this person was Xiao Man's cousin.

“...”

"These two... Is it necessary to be so affectionate?" The cousin saw the two hugging each other, her face was full of black lines, thinking that her cousin was such a pure and lovely girl, and she actually degenerated into this, the power of love... It's too scary to imagine.

"Don't sleep!"

"Get up, get up!" shouted my cousin.

moment

The two looked at their cousin with confused faces, not knowing what was going on for a while.

"You also slept so late in China?" The cousin looked at the two of them who looked at a loss, and said helplessly: "I remember that you are going back tomorrow, right? I'll take you on another tour of New York. ”

“...”

“...”

Yang Xiaoman was not a sleepy person before, but since he was with Xu Mang, he gradually became contaminated with some of his vices and liked to sleep very much.

"Sister!"

"We don't want to go anywhere, we just want to sleep all morning, then eat and drink in the afternoon, and then get on the plane home. Yang Xiaoman twisted his little face, angry but didn't dare to speak, and said, "Sister... Don't disturb the two of us sleeping. ”

How could Cousin Xiaoman let the two of them continue to sleep, today she specially asked for leave from school, in order to implement the plan she thought of last night.

soon

Yang Xiaoman and Xu Mang sat in the living room eating breakfast with a stomach full of anger, toast, bread, jam, fried eggs, milk, this kind of Western-style breakfast made Xu Mang unbearable, and he didn't like sweets.

"Cousin?"

"Is there a national goddess hot sauce?" Xu Mang asked, "It's called The Godmother in English." ”

"Nope!"

"Do you like to eat or not? Cousin Xiaoman said expressionlessly.

Alas...

There is not even a national goddess hot sauce, how to eat this breakfast?

Xu Mang finally sandwiched an omelet between two slices of toast, smeared a layer of mustard on top, and ate it with tears in his eyes.

"Xu Mang?"

"I still don't believe what you said yesterday. The cousin smeared strawberry jam on the bread and said with a blank face: "You said that you solved it at the time, this is because you don't want to spend too much time on it... Isn't that the case?"

"That's right!"

"I don't think it's difficult at all, it's just that it's extremely complicated. Xu Mang said indifferently.

Xu Mang didn't talk nonsense, yesterday when he finished eating, he analyzed the speed of the topic, and finally thought that it would take about twenty minutes to turn on the beast mode, while ordinary people would need at least one and a half hours.

duration

You can't make a mistake yet, and if any small detail goes wrong, you have to recalculate it.

This question tests students' patience and perceptiveness.

Although Cousin Xiaoman believed Xu Mang's words, she still pretended to be disdainful at this time, and said to Xu Mang: "You guy bragging, I wonder why Xiaoman would fall in love with you as a person who likes to brag." ”

“...”

"Sister... Xu Mang is really powerful. Yang Xiaoman resisted weakly, but her resistance was useless.

soon

Breakfast was finished, and Cousin Xiaoman left her home with the two of them.

But as I walked around, I felt that something was wrong.

How did you end up at Columbia?

"Xu Mang!"

"At the moment you have two options. Xiao Man's cousin said solemnly: "Accompany our two sisters to go shopping, or you stay alone in Columbia University and solve my problem." ”

Xu Mang: Σ('д′*ノ)ノ

it!

What a heavy scheming.

The lesser of two evils... Xu Mang chose to solve the question.

Shopping

Joke... Every time I accompany Xiaoman shopping, I almost don't die, and now there is another cousin of hers, isn't it even more tragic.

"Walk slowly!"

Xu Mang looked at the backs of the two sisters leaving, and felt a little lonely for a while, he was not a person who was afraid of loneliness in the past, but after being with Xiaoman for a long time, he gradually became a little unaccustomed to loneliness.

"I didn't expect this dwarf and shriveled to have such a big impact. Xu Mang sighed, his eyes returned to the huge blackboard, a blackboard could not fill the process of solving the problem, Xu Mang noticed that there were more than 20 blackboards prepared on the side, all of which could be moved up and down, left and right.

"The system... Turn on Beast Mode!"

【Beast Mode Activation】

Open the whole!

Xu Mang picked up the chalk on the side and scribbled frantically on the blackboard.

Boom,

It's outrageously fast.

Ten minutes later,

It was class time, and the students were holding their books, and when they passed by Xu Mang's side, almost all of them involuntarily stopped and looked at him with a confused expression.

Since they were facing away from the crowd, the students didn't know that it was Xu Mang who was solving the problem.

However, most of them joined in the fun, just stood for a while and left, but the expressions of those students of mathematics, physics and chemistry became a little hideous.

"Bob... This... Do you know this guy?"

"I don't know!"

"I don't know who he is... But it's so powerful, and the speed of solving the problem is so fast, I just don't know if he's right. ”

"At the moment, there seems to be no problem. ”

The crowd began to discuss, and most of them were guessing who this guy was, but because class was about to start, the students did not stay long and left behind Xu Mang.

soon

In the multimedia classroom of the mathematics major,

As the first-year Columbia undergraduates discussed what had just happened, a mysterious man was trying to solve a problem that was extremely complex and time-consuming, and he was so fast that it couldn't be explained by science.

Then

An old man with white hair came to the classroom, and he was the mathematics professor who was teaching today.

"Professor Angus!"

"Did you notice anything unusual on the way?" a girl raised her hand and asked the old professor, "Did you notice a boy?"

Strange?

Schoolboy?

What's the situation?

The professor said curiously, "I came from another passage, and I didn't notice anything unusual or a boy you said. ”

"Professor Angus!"

"Professor Mu's problem of applied mathematics seems to have been solved, and I took a video!" the girl took out her phone and clicked on a video she had taken.

Professor Angus walked over to the girl and looked at the back of a boy on the phone screen, holding chalk and scribbling frantically on the blackboard, but... It's not graffiti, if you look closely, you can see that he's answering a question.

It's weird...

Can his brain keep up with his hand?

Scribbled, right?

Professor Angus knows that the difficulty of this question is not particularly difficult, but the process is extremely complex, requiring amazing patience and strong insight, but judging from the video, there is a high probability that it is making trouble, and the answer is given directly without thinking, how is it possible.

This is unscientific!

"Go and see if the student is still there. Professor Angus said to the girl.

"Okay professor. ”

Words fall,

The girl hurried out of the classroom.

"Alright. ”

"Now let's start the class. ”

Professor Angus had just turned on his computer when he returned to the podium and was gasping for air.

"Professor!"

"I think... You... You'd better see for yourself!" The girl said breathlessly, "It's just shocking!"
