Xu Mang was lying on the bed, listening to the sound of water running, and his brain was thinking about how to explain the next thing to Xiaoman.

moment,

The sound of water flow stopped.

Immediately afterwards, the violent airport walked out of the bathroom, then walked to Xu Mang and said softly: "Sleep on the side."

Xu Mang didn't hesitate and quickly lay down on the cold side.

When Xiao Man lay down, Xu Mang slowly walked up to her, hugged her in his arms, and said with a smile: "It smells so good. What kind of shower gel did you use?"

“Very expensive!”

"The shower gel I wash costs several thousand." Yang Xiaoman twisted her body and leaned into Xu Mang's arms as much as possible. She leaned her head on his chest and said softly: "How have you been doing these past two days? Old man.

Is it so enthusiastic?”

"ah?"

"Oh, it's nothing, just because you are so beautiful." Xu Mang said with a smile: "Xiaoman, I have something to ask you?"

"snort!"

"I knew you didn't have good intentions." Yang Xiaoman rolled his eyes and whispered softly: "Just tell me."

"Can you remember more questions?" Xu Mang said: "I just received a call from Teacher Teng from the Mathematics Department of Jiangsu University, reminding me that I am the question writer of this Zhejiang Provincial Mathematical Olympiad Competition. It was decided last year. As a result, I gave

Forgot"

"I think we should let students in Zhejiang Province experience the types of questions in some international competitions and see how far the gap between the so-called top students in high schools is and the top international students." Xu Mang said: "It's not like we have banned Mathematical Olympiads, why are there still so many

Multiple Mathematical Olympiads?”

Yang Xiaoman shook his head and said silently: "I don't know, we were really miserable in the International Mathematical Olympiad recently."

Xu Mang didn't know much about these things, but he used Douyin to watch various science popularizations by awesome people, and then discovered a problem. Many people defined the mathematical ability of foreign students as mentally retarded.

certainly,

Xu Mang didn't know if those big guys were right, so he went to Princeton University this time just to see if the real situation was the same as what the so-called big guys on the Internet said.

In fact, Xu Mang already had an answer to this question, but he couldn't resist his stubborn character.

"Fool!"

"Have you finished getting your visa?" Yang Xiaoman asked.

"Um."

"It was done before I came here." Xu Mang said with a smile: "That's it, it's settled, help me memorize some questions when the time comes, uh, just remember the most difficult questions."

""

"Can you be a human being?" Yang Xiaoman rolled her eyes: "The contestants come here to compete, not for your autism."

Xu Mang said awkwardly: "I'm just going to experiment. Anyway, I will tell Teacher Teng when the time comes. He is the general person in charge. I think it is a trend to move the topics closer to internationalization. We need to take a long-term view."

"What if it's exposed?" Yang Xiaoman said worriedly.

"It's none of my business." Xu Mang said with a serious face: "Without the nod from the general manager, can I ask such a question? Without the nod from the general manager, can the contestants do the question?"

""

"You are indeed not a human being!" Yang Xiaoman said helplessly: "You beast!"

The words fell,

Xiaoman's pretty face turned red and she whispered, "Hey beast, when do you do what a beast should do?"

"sorry!"

"I am a man worse than a beast." Xu Mang said seriously: "Sleep!"

Yang Xiaoman: convex

this day,

Finally heading to Princeton University.

Xu Mang has applied for the temporary position of assistant coach and is setting off with the team.

The leading professor was named Wu, a mathematics professor with a good temper. During the conversation between Xu Mang and Professor Wu, he discovered that Professor Wu was not only good-tempered, but also seemed to be a real giant. He knew many Fields Medal winners.

"well"

"We were originally the champions of this competition." Professor Wu said, "In the end, you were suspended, which was beyond my expectation."

"Isn't this their usual trick? If you can't beat them, you will be banned from the competition." Xu Mang said with a smile: "By the way, Professor Wu, which field of mathematics are you studying?"

"Partial differential equations, metric geometry, and applied problems of probability." Professor Wu said, "Have you done any research on these problems?"

"No!"

"I major in physics." Xu Mang shook his head hastily. He really had no feeling for mathematics.

at this time,

There's still an hour left before takeoff.

Xu Mang simply walked around the airport with Xiao Man. It was strange that no one came to see off the team that represented the country.

"well?"

"What's going on over there?" Xu Mang pointed to a group of people in the distance and asked curiously: "Did something happen?"

"Maybe he's a star."

"Didn't you see that everyone was taking pictures with their mobile phones?" Yang Xiaoman said: "Only celebrities can have this kind of formation."

"oh"

After watching it for a few minutes,

Xu Mang observed a man wearing a mask walking to the so-called VIP lounge with support, and then a group of people stood outside the glass wall, taking pictures with their mobile phones.

"Who is this?"

"Why don't I recognize him?" Xu Mang said with a confused look on his face: "Is he a big star?"

""

"I don't know him either. Maybe he's someone who just debuted." Yang Xiaoman shook his head.

Well

It just looks like this,

They are not even 0.1% as handsome as this beautiful person.

"Why can't we rest in the VIP room?" Xu Mang asked: "We are going to participate in international competitions and win international honors."

"Stop complaining."

"If you are really unhappy, just buy the airport." Yang Xiaoman said angrily: "This is reality."

for a long time,

Xu Mang and his party boarded the plane and began their next journey

get off the plane,

He took a bus directly to Princeton. Since he had reserved the room in advance, he only needed to pack his bags and check in. However, Xu Mang encountered a little trouble because he was temporarily inserted as a teaching assistant and there was no room for him.

In the end, he could only live in the same room with Xiaoman. Professor Wu knew that the two were lovers, so he simply turned a blind eye, but he still did not forget the kind reminder.

"Don't stay up late at night, and don't do anything that has nothing to do with rest." Professor Wu said seriously.

Xu Mang:???

Yang Xiaoman:???

Soon the two of them understood the meaning of Professor Wu's words.

this night,

Nothing happened.

The next day,

Princeton University,

Xu Mang felt the atmosphere of a famous private research university for the first time, but the house was a bit old and felt like it was a house that was more than a hundred years old. Although it was quite classic, it felt a bit dangerous.

Due to a tight schedule, Xu Mang started to help Professor Wu guess the questions after attending the opening ceremony as a teaching assistant.

The rules of the competition are very simple.

There are only two days, and each day has only one paper with fifty questions, for a total of one hundred questions.

Full score of five hundred,

The individual award will be based on the one with the highest score, and then ranked in order. The team award will be based on the total score of the five people, and then ranked in order.

at this time,
