"What's right?"

The graduate student was a little puzzled, and wanted to take a closer look, and was shocked: "This is...?"

Feng Xingshen reacted. He hurriedly stood up and collected the information on the table. He was relieved to see his students withdraw their eyes in due course.

The graduate student is still in astonishment: "Right?"

Feng Xingshen nodded.

Thinking of something, he quickly picked up his cell phone and called Xue Xi on WeChat.

It was late at night, and the little girl seemed to be asleep, and the phone rang for a long time before being answered. The little girl seemed uncomfortable with this kind of communication, and only gave a "feed" after answering for a while.

The voice is low, dull and indifferent, with dim sleepiness.

Feng Xingshen hurriedly said, "Have you sent the result of this conjecture to others?"

The other side paused again, "No."

Feng Xingshen breathed a sigh of relief, and he solemnly said: "Before you publish it, don't show it to anyone else for the time being. There are many people in academia who dominate other people's labor."

"...Oh, got it."

The other party's tone is still very calm, giving Feng Shengshen a feeling that the emperor is not in a hurry.

He coughed and asked: "Did you prove this conjecture alone?"

The other side paused, and replied very seriously: "No, my grandpa proved two-thirds. It should be visible on the draft paper he gave you."

Feng Shengshen could see it, but this conjecture was proved by this method. Many people have tried it, and they often get stuck at the last step and can no longer proceed.

Therefore, the first two-thirds are really nothing but an introduction, and the most rare is the latter one-third!

Even if the little girl said that this conjecture was proved by herself, there was no problem.

Feng Xingshen had further trust in her character.

He treated her like a junior and liked her a little bit more. He smiled and said, "Which paper and magazine do you want to publish in?"

The other side paused: "Huh?"

Obviously some doubts.

Feng Xingshen opened his mouth: "You have to organize it into a paper and submit it to the most authoritative mathematics journal. Will you write a paper?"

"……will not."

Feng Xingshen smiled instead: "I can help you with this. I suggest you submit your paper to Inventiones-Mathematicae. Your conjecture can definitely cause a sensation in the international mathematics community!"

But the other party didn't seem to be aroused at all, and still calmly replied: "Okay."

Feng Xingshen: "..."

If it were him, he would definitely get up overnight to sort out the papers, but the other side's attitude...

He asked again: "Are you free lately?"

"No."

"Busy studying?"

"No, I'm going to participate in the National Mathematical League." Xue Xi hasn't done enough questions for a week. In order to show respect for the competition, she decided to do well on Mathematical Olympiad questions in the next three days.

"..."

Feng Xingshen felt that the world was illusory again.

How do you compare to a group of high school kids who have proved Bartra’s conjecture?

But he thought that the little girl was still a high school student and couldn't help swallowing: "Are you a third year in high school?"

"Ok."

"Okay, if you don't mind, I will find a reliable person to help you write the thesis!"

"Then please."

Feng Xingshen felt relieved. At the last moment, he asked: "We just talked a few words in the group, why do you trust me so much and send me the manuscript?"

Although he is already a mathematics expert in China and his character is guaranteed, even he cannot guarantee that he will not be tempted in the face of such a paper...

This is a glorious event that can be recorded in history!

Upon hearing this question, Xue Xi, who felt inexplicable, replied slowly: "Didn't you ask me to help you prove this difficult problem?"

Feng Xingshen:? ?

-

Xue Xi, who was awakened in the middle of the night, did not take this matter to heart after hanging up the phone, and fell asleep again.

In the next three days, she began to study the league questions seriously and put all her energy on learning.

Old Mrs. Xue tried to taunt her several times, but she was suppressed by Xue Sheng, while Liu Yiqiu and Xue Yao seemed to be hit by the piano. They were honest.

After three days, Xue Xi packed his bags and went to participate in the national league.

The participants in this competition are basically the same as those who went to the Mathematical Star. There are still three girls in the international school, and the other two girls live together.

After Lao Liu asked Xue Xi what she meant, he let her live alone.

On the bus, Fan Han looked at the girl wearing a peaked cap, sitting alone in the last row, pursing his lips, he sighed, the bus was full of people, and when he checked into the hotel, he went to look for her Please comfort her.

Five hours later, the car arrived at the hotel.

When checking in, Fan Han deliberately moved slowly, wanting to hear Xue Xi's room number, and then after Xue Xi handed the ID card to the front desk, the front desk smiled and said, "Hello, that's it. There are no single rooms in our hotel. , So can I upgrade you to the presidential suite for free?"

The rest of the people are dumbfounded. Is there such a good thing?

Fan Han is also dumbfounded. The presidential suite is on the 28th floor. If you don't live on that floor, ordinary guests can't get there at all!

Xue Xi didn't think much, "Yes".

Immediately a waiter came to help her with luggage. After a few people left, Fan Han thought about it. He still had a lot of pocket money. When he looked back and wanted to upgrade the suite, he saw that there were others checking in: "Excuse me for the single room. Any more?"

"Yes, sir, how many floors do you want to live on?"

Fan Han was stunned, a little stunned. He didn't understand what was going on. When it was his turn, after he asked for a room upgrade, he was told, "Excuse me, our hotel suites are all packaged, and there is no room now. The room is upgraded for you."

Fan Han:? ? ?

This night, Xue Xi slept very well, and breakfast was delivered to the room the next day. When the meeting time was reached, she got on the bus in good spirits.

The group came to the examination room. After Liu gave a few more instructions for the examination, Xue Xi followed the crowd into the door. After she found the examination room, she took out the admission ticket and entered the classroom.

Immediately, I saw an acquaintance-Liu Liyuan.

Coincidentally, Liu Liyuan happened to be sitting next to her.

Since the last incident, Liu Liyuan has held a grudge in her heart. She spread Xue Xifu's second-generation enjoyment everywhere, but Xue Xi took the first place and completely slapped her in the face, making her a joke!

During this time, she couldn't calm down and study hard. She knew that she had no hope of winning.

Liu Liyuan clenched her fists bitterly, she suddenly stood up, picked up her pencil case, and slammed Xue Xi viciously. Since she couldn't win the prize, then the instigator should not think about taking the exam!

Then-"pop!" Xue Xi grabbed his wrist.

A teacher looked over and said, "What's the matter?"

Liu Liyuan's eyes narrowed, and then she fell back and overturned the table and chairs behind her. She endured the pain in her waist and shouted, "Teacher, she hit me!"

Fighting in the examination room, both sides will be disqualified!
