“Tuk-tuk-tuk.”

"Please come in."

Shanghai Peking University, Lin Xiao’s office.

After hearing someone knocking on the door, Lin Xiao said something without raising her head.

The door opened, and a voice that sounded old but powerful came.

"Lin Xiao, why don't you go out and rest on New Year's Day?"

Hearing this familiar voice, Lin Xiao finally raised his head, and then said with a smile: "Teacher Xu."

The person who came was none other than Xu Ji, his former mentor.

Xu Ji walked next to him with a smile, and looked out the window at the same time. The cold winter outside was eroding people's hearts, but it did not stop people from going out to play. The students of Peking University were enjoying today, which had only begun since the National Day.

Some holidays bring smiles to my face.

"There's nothing interesting to see. I admired the scenery of Beijing University when I was a kid, but after staying here for a long time, I no longer feel that way. It's better to stay in the office and do research."

Xu Ji smiled and saw Lin Xiao lowering his head again, looking at the scratch paper on the table filled with various formulas and calculations, shaking his head slightly, and then looking out the window again, "Our society has become so

Well, you have to go out and take a look and see what you have achieved."

Lin Xiao raised his head again, picked up the teacup next to him and took a sip. Suddenly he realized that he had not made Xu Ji a cup of tea or anything, and since today was a holiday, his students went out in twos and threes with their friends.

After playing, he was the only one left in the office.

As for him, no one is looking for him. After all, everyone now basically knows that he is studying a very difficult topic.

The chief scientist wants to research a topic, so naturally no one dares to disturb him.

Probably only elders with relatively close relationships like Xu Ji could come to him.

He stood up, went to make tea for Xu Ji, and responded: "Of course I can see that society has gotten better. Of course, although it does have something to do with me, it is not so good that all the problems have been solved."

"Oh?" Xu Jilai became interested, "What other problems do you think there are?"

"We humans are not free enough."

"Not free enough?"

"Well, for example, we can't leave the solar system yet."

"Uh..." Xu Ji didn't know whether to laugh or cry, and said, "Well, this kind of problem is not something I can study. I'm not very interested in it as a math major."

"However, you can be considered an outlier among those of us who study mathematics."

Lin Xiao made the tea, handed it to Xu Ji, then returned to his seat and asked with a smile: "Is it possible that the physics community and the mathematics community are still arguing about whether I am a mathematician or a physicist?"

Xu Ji smiled and said: "It seems so. I don't know the specific situation. After all, I haven't attended those mathematics conferences for a long time... Oh, by the way, this year's International Congress of Mathematicians will be held soon. You should also pay attention.

Have you received the invitation letter?”

Lin Xiao opened the drawer next to the table and took out the invitation letter.

"Well, I received it a few months ago, inviting me to give a one-hour report."

"Then do you plan to go?" Xu Ji said, "Oh, by the way, can you go abroad now?"

Lin Xiao smiled: "You also said that our society has improved. Although there are still some problems, there is no problem in going to France."

With the current strength of their country, those conspiracies and tricks in the past are basically no longer dared to be used against them.

So there is no need to worry about problems like assassination happening.

At that time, sufficient protective forces will be arranged around him.

Of course, the most important thing is that with Xiaomi here, no conspiracy or conspiracy in this world can be used against him.

Just like the unlucky Secretary of State who was imprisoned, all the problems that occurred with his mobile phone were naturally caused by Xiaomi.

Xiaomi can directly control his mobile phone, and then directly hijack all text messages and calls sent to this mobile phone. At the same time, he can also connect the phone, and directly simulate the electromagnetic waves of the Secretary of State's voice, so that the other party will not be suspicious at all.

So as long as these conspiracies and machinations require the use of electronic devices to communicate, they will not be able to escape Xiaomi's "eyes".

Of course, this is just the simplest.

Nowadays, when any electronic device in the world is produced, a program will be implanted by Xiaomi. This program cannot be discovered even by the manufacturer responsible for the production.

Therefore, with such a function, when all electronic devices in the world are updated, they will be completely under Xiaomi's control.

Therefore, now Lin Xiao is basically not worried about anything else in the world that can threaten him. Even if it is a nuclear bomb attack, Xiaomi can turn the nuclear bomb into a piece of useless waste before it is launched.

Iron, who makes the nuclear bombs of various countries very safe in terms of safety?

"That's good." Xu Ji smiled and said, "Then what kind of surprise do you plan to bring to our mathematical community again?"

"I remember the 2026 conference. I had a video meeting with you at the closing ceremony. As a result, you came up with a one-way function that directly falsified the p=np problem. Will you have to do it again this year?

Did you bring us a surprise?"

As he said that, Xu Ji couldn't help but said: "It's a pity that in the past four years, you have been engaged in aerospace. We in the mathematics community are all very sorry."

Lin Xiao smiled: "What's such a pity? There are many talented people in the world, so you can't always keep an eye on me."

"I estimate that your talent is unprecedented and unprecedented."

Lin Xiao waved his hand, then looked down at the draft paper on the table and said, "As long as I solve this problem, I'll go. If not, forget it."

Xu Ji was stunned for a moment, then he raised his head and asked: "What you are studying now is the problem you plan to report? I asked you why you didn't do other scientific research during this time, but were at school...

Um?"

"Wait! Zeta function...are you studying the Riemann Hypothesis?"

"Yes."

Lin Xiao nodded slightly.

Before, except for the people at Yueshisi who knew that he was studying the Riemann Hypothesis, no one else knew.

Of course, he did not hide anything. Although the purpose of studying the Riemann Hypothesis is to solve the problem given on the moon monument, but also, the Riemann Hypothesis is the crown of the pinnacle of human mathematics. Once it is solved, it will naturally also be solved.

It needs to be announced to the whole world.

This is an important milestone for the mathematical community.

Of course, it's no wonder that Xu Ji next to him was so surprised.

His eyes were full of surprise, and soon, the surprise turned into happiness.

"Finally, you finally started to study the Riemann Hypothesis. It seems that I can see the solution to this problem in my lifetime."

After saying that, Xu Ji patted his head again and said with a smile: "Oh, look at me, what are you talking about? It seems that this problem will be solved in July this year."

Lin Xiao smiled, not being modest, and said directly: "Probably."

"Hey, I just like how you agreed so straightforwardly. You are worthy of being my student." Xu Ji laughed and said, "It's great to have such a talent."

Then he drank the tea that Lin Xiao had just made for him in one gulp, then stood up and said, "Then I won't bother you anymore."

"I'll just wait for your good news."

Lin Xiao smiled and said: "Teacher Xu, just wait, but you also need to have a good rest. Don't be so tired today on New Year's Day."

"What the hell, he's only over seventy years old. Why don't you look at your doctoral supervisor. If Professor Searle celebrates his birthday this year, he will be 104 years old."

"Professor Serre..." Lin Xiao was stunned and whispered in his mouth. Speaking of which, he may not have had a good contact with Professor Serre for a long time, as if it was four years ago.

But at this time, Xu Ji said: "Oh, by the way, four years ago, in 2026, I also attended Professor Searle's 100th birthday party, and he even talked to me and said

I sent you a banquet invitation, but you didn’t reply to him or anything."

"He seems a little angry."

"But he also knows that it's not convenient for you to go abroad. He's mainly angry that you didn't reply to him. It's been so many years, so you guys should have forgotten about it."

Xu Ji waved his hand, "I won't say it anymore, I have to leave."

But when Lin Xiao heard what Xu Ji said, she was stunned.

He had never received that invitation letter back then. If he had received it, he would have sent his most sincere blessings to his mentor first, and then explained the reason why he could not go.

He frowned, but he did not ask Xu Ji, but said: "I understand, thank you, Teacher Xu."

"Um."

Xu Ji waved his hand and left here.

Lin Xiao thought for a moment and finally called out Xiaomi, "Xiaomi, go check and find out where the invitation letter sent to me went."

After a while, Xiaomi brought back the answer.

"After the bodyguard received it, he was worried that I would go to France to attend the banquet and cause an accident, so he didn't tell me about it?"

After learning that it was for this reason, Lin Xiao fell silent.

Finally he sighed, "Okay, I get it."

Xiaomi hummed and said: "Master, your bodyguards are so ignorant. They did such a thing without telling you. Do you want me to teach them a lesson?"

Lin Xiao said angrily: "Don't mess around with things. There's nothing to say about this matter. They may have done something wrong, but they can still be regarded as... their responsibilities."
