When a blonde saw Xu Mang, she felt like she was crazy. Her eyes were full of adoration. She sat on the edge and asked questions. She was embarrassed. She didn't know what to do for a while.

"Ellie!"

"Be reserved... You will scare Professor Xu." A dark woman on the edge said hastily to the emotional ally.

As a result,

the black woman said with embarrassment: "sorry, Professor Xu, Ellie's major is condensed matter physics. Her idol is you. When you see her idol for the first time, you will inevitably get excited and make you laugh."

Eh?

She... She is Ding Jun's girlfriend?

It seems that they are not the same as those in their own impression. Are they too common?

Although Xu mang can't recognize the European and American people's looks, they can still be distinguished from each other. This girl named Ali is not like... Except for her blonde hair, other conditions are not so good.

What's the situation?

Why do friends around you like to find ordinary girls?

Are you vulgar?

"Professor Xu?"

"How did you come here all of a sudden? I heard Jun say before that... He and you are friends, and the relationship is very good, I fantasize that one day I can meet you, but this dream has come true. " Ellie said to Ding Jun, "dear, let's change to a restaurant and go to Michelin 3-star."

"..."

"do not come to Xu Du, do not need to go to Michelin 3-star?" Ding Jun said helplessly.

"No!"

"it's because Professor Xu is here that we are going to eat in Michelin 3-star." Ai Li is a very stubborn and wayward girl. At this time, her small temper surged up and seriously said, "Professor Xu seldom comes here. We must treat him well."

"No, no, no!"

"No need... Thank you." Xu mang saw that Ding Jun's face turned black. It was the couple who might quarrel, and said with a quick smile, "it's very good here. I let Ding Jun book here."

"Ah?"

"Oh... Then... That's it." Said Ellie.

After a while,

people began to order, but Xu mang was still the same as before. He ordered a steak set meal and a pasta set meal. The price was not cheap. For these two packages, they cost about 199 US dollars, equivalent to about 1400.

"Lying trough!"

"Ding Jun... Why is it so expensive here?" Xu mang said in Chinese: "Temo's 200 dollars, converted into 1400 dollars!"

"..."

"I said you calculate money like this?" Ding Jun helplessly said: "directly according to the exchange rate? Isn't this a rogue? "

Xu Mang:???

What do you mean?

Don't you need to come at the exchange rate?

"Is the exchange rate between our country's money and the US dollar already one to one?" Xu mang asked cautiously, "I'm actually a fake Chinese?"

"You..."

"this..."

"forget it... Anyway, you have a wife who is very profitable." Ding Jun gave up the debate on purchasing power with Xu mang. He can see that Xu mang is an idiot in this respect. It is better to have a fight with an understanding person than to have a debate with an idiot.

At this time,

Ellie said in the same words: "Professor Xu... Xu, you... Don't argue with him. He... He... Is a fool."

Xu mang looks at Ai Li in surprise. He doesn't expect her to speak. Although she talks intermittently, the basic meaning is very clear. It seems that we should be more careful when we speak in the future. It seems that the whole world is speaking Chinese.

"You have a good command of Chinese... Did you learn from this idiot?" Xu mang asked with a smile.

"Well!"

"After all, I'm his wife." Ellie said with a smile, "it's normal to know your husband's language."

Yeah!

Good!

This marriage... I got it!

Xu mang was satisfied with Ellie's performance and allowed them to get married on the spot. Then he said to Ding Jun, "Ding Jun, it seems that you two are true love. If you look like this, you are not as handsome as I am. You can find such a good girl... It's just natural that you can find such a good girl

Ding Jun is so angry. Why is this guy still so cheap?

At this time,

the waiter delivered the lunch they ordered, and then ate it happily. At first, Xu mang thought that he had ordered an ordinary steak, but he came up with a large piece. Later, he realized that it was a Tomahawk steak, which was very large.

Not to mention,

this steak tastes good enough. You can only feel like you are eating steak when you eat this steak. You can feel that you are just eating beef when you eat other steaks."Ellie."

"Has your group encountered a problem recently?" Ding Jun said seriously: "why don't you ask Xu Mang and let him solve this problem."

In a word,

the five people on the scene, including Ai Li, came to their senses in an instant. They were all members of a research group. Recently, there was a problem that trapped several people. Even the tutor was at a loss. They were already on the verge of despair. Now Professor Xu is here, and this problem can finally be solved.

"Well!"

"Professor Xu... Can you help us?" "It's a computing problem... No one in our school can solve it, including the professional math professors and students, and they can't do anything about it."

Xu mang thinks it's also... Brown University, but it's not at this level. It seems that the school can only rank among the top ten in the United States.

"Oh..."

"no problem!" Xu mang nodded.

Soon,

after lunch was finished,

Xu mang was directly tied to Brown University by Ding Jun and his group, and all the way down to the famous barrow Holly experimental building, which is a comprehensive building of engineering and physics. In fact, the level of brown University is quite high.

In particular, undergraduate and doctoral students have a very high admission threshold, which is one of the most difficult universities in the United States.

Although the number of university students is increasing, Brown University still maintains a small and elite education. According to Ding Jun, there are only 6000 undergraduates, 2000 graduate schools and 700 full-time teachers.

As a result,

on this scale, seven Nobel Prize winners were selected.

"Professor Xu... That's the problem." Ellie pointed to a group of complicated calculation processes on the computer screen, and said helplessly, "we were stuck for three weeks... We found a lot of people, and they all said that we couldn't solve it."

When Xu mang saw this large complex formula, he couldn't help standing still. It seems that this is not a simple condensed state, but a topological insulator with topological concept, which is one of the most important quantum materials in condensed matter physics.

Ha ha,

it's not simple!

Ding Jun this boy also learned the routine, which is not a matter of raising one's hand. He should raise his hand twice.

In the face of the sudden silence of Xu Mang, the people present are very nervous, for fear that Xu mang will answer No. if he can't even... Basically, it can declare that the research project has failed.

"This question..."

"it's not very difficult. Do you have a pen and paper?" Xu mang said with a smile.

All the people were stunned. This is the solution? Just a look?

For Xu Mang's magical operation, most people are confused. He just glanced at the formula. He didn't even ask what the experiment was. It can be solved directly. It's totally out of line with the common sense of science.

After a moment,

Xu mang got the paper and pen, sat alone in front of the computer and began to calculate the problem, not to mention... This problem is really difficult. The difficulty is not thinking, but calculating steps, which are particularly complex.

It's estimated to take at least two hours.

Two hours...

too long!

"System... Open animal mode!"

In the next second, Xu Mang's Unicorn arm reappears in the lake and writes a piece of soul Waltz between the pen tip and the paper.

Shua Shua Shua...

soon,

soon,

soon enough, people were frightened, their facial expressions gradually distorted, and they exchanged the fear in their eyes, incredible emotions, and even a little helpless.

Is this...

is it written by body function without brain?

Ai Li and others observed that every time Xu mang calculated the answer, he hardly needed to wait. The answer came out directly. How did the answer come out? Several people imagined many possibilities, and finally they thought it was graffiti.

How can it be so fast? Is this the speed that human beings should have?

Robot?

Maybe only robots can do it. Of course, it can be et.

"Is this... Is this an illusion?"

The black woman murmured a few words, her pupils contracted slightly, and she was staring at Xu Mang's calculation process. Although she couldn't see clearly, this did not prevent her from feeling shocked at the moment, which was more intense than before.

Hallucination?

No, this is in reality.

Several people answered the black woman's question in their hearts. Although they didn't want to accept the fact, the fact was in front of you. Whether you would like to accept it or not, this is the fact, and the problem is being solved at such a speed.At this time,

Xu mang suddenly stopped writing and sat in a chair in a daze.

The sudden behavior scared many people at the scene, thinking that he had encountered some problems, which could not be solved in a short time.

"I..."

"I'm thirsty... Can I have a bottle of water?" Xu mang looked back and said to the group of people around him.

"..."

"..."

"

"... "

this...

good naughty Professor Xu!

It's too skinny!

Soon,

Ai Li took a bottle of water, handed it to Xu Mang and said respectfully, "Professor Xu... Here you are."

"Thank you."

Xu mang took a drink and then went on with his calculation.

Shua Shua, Shua Shua,

is still the speed, or the emotion that can not be calm. At this time, the laboratory is silent, only the sound of continuous friction between the pen tip and the paper surface.

"Good..."

"it's hard to understand... I can't understand it."

A boy lowered his voice and said to his companions that from the moment Xu mang took up his pen, the boy had lost his face. The confused expression has not changed from the beginning to the present.

According to common sense, he is a condensed matter physics major, and his mathematical ability is excellent, at least in the field of application. As a result... After seeing Xu Mang's calculation process, he felt that he might have learned a false mathematics.

Otherwise, why can't you understand Professor Xu's calculation process?

For a long time,

after Xu mang wrote down the last calculation process, he sighed in silence. By now, it was all over. He put down his pen... Looked back at the people and said calmly, "it's over... The so-called problem has been solved."

“???”

“???”

“???”

That's the end?

Just... Less than 15 minutes!

Is it right?
