early morning.

Lu Zhou is sitting in the cafeteria of clincia Hotel, enjoying bread and coffee, checking the unread email in the mailbox according to the Convention, and browsing the latest research results of number theory, algebraic geometry, differential manifold and other directions marked by him on arXiv.

These days, the whole mathematical world is quiet, there is not much interesting news released. In professional academic forums such as mathover folw, most of the discussions are not academic issues, but rather gossip about the mathematical world.

Even though not everyone has been invited to the IMU conference, most mathematicians are paying close attention to the upcoming World Conference in St. Petersburg.

Just as the boat was browsing a post about the prediction voting of the fields prize, a Russian man with sunglasses on his neck sat opposite him and whistled.

"May I trouble you to stay in the hotel today?"

From the computer screen away from the line of sight, the boat will inquire into the line of sight to him.

"What happened?"

"If I have to say, there are some problems," said maxim, taking off the sunglasses at the neckline and wiping them with glasses cloth. "Someone intruded into the power grid system of St. Petersburg and inserted some dirty code into it. And according to our national security intelligence office, it could be a premeditated operation. "

Lu Zhou said without words: "I have no idea Can it still be without premeditation? "

"You don't understand me," said maxim, looking up at the boat with a smile. "I mean, it could have been a premeditated murder against you."

The atmosphere on the table froze for a moment.

It's like being silenced. It's quiet.

This is probably the first time.

His life is really under threat.

The throat was slightly dry, and the boat took a sip of coffee.

It took three seconds to recover his composure, he said, putting down his coffee cup.

“…… To be honest, it's a bit far fetched. It's just that the failure of the nuclear power plant is a bit far fetched when it comes to murder. "

Blow up a nuclear power plant to deal with him

Next to the Helios nuclear power plant is St. Petersburg, the second largest city in Russia. Even if controllable fusion technology is no longer clean and safe, it has a nuclear character.

If things are exposed, it's not just a matter of regional disputes.

Even if we slide to the edge of war, the land boat will not feel strange.

"More than 80% possibility, at least we think the strategic value of someone is obviously more important than that of the Helios fusion power plant, and it can also successfully destroy the friendly relations between us and our neighbors. After all, if you are in trouble in Russia, it is not a sentence of" we are very sorry "that can be dismissed casually."

Wearing the clean sunglasses on the bridge of his nose, Maxim raised his eyebrows to the boat, pushed away the chair and stood up.

Through sunglasses, he stared at the boat with serious eyes and continued.

"In a word, the situation is that some people are going to be bad for you. We are not sure if they have plan B waiting for you after plan a fails. So in order to avoid accidents, we hope you can try to control the scope of activities in this hotel. Here we have 100% assurance to ensure your safety. If you are too far away from here, the figure may only be 90% or even 80%. "

"I see," Lu Zhou nodded, his eyes moved away from Maxim's face, and continued to look at the computer screen. "Although I don't know who looks up to me so much, I will try to control the range of activities in the hotel."

He had no intention of wandering around during the IMU conference.

Since someone has been following him, it's better to be careful.

"That's the basic situation. I have another important thing to deal with in a moment. I won't stay here. Have a good day."

With a gesture of goodbye, Maxim smiled and walked to the entrance of the cafeteria.

However, as he was passing by the seat of the land boat, he suddenly glanced at the left and right, pretended to be careful and lowered himself down, and whispered a word.

“…… I'm afraid I'll take you to that place where there are many good girls next time. "

Hearing the sudden sound, the boat that just took a sip of coffee almost didn't choke.

Dry cough put down the cup, Lu Zhou took the paper towel to wipe his mouth, black face said.

“…… Thank you. No more. "

"Ha ha, don't be shy, my friend. Besides science, life has many other interesting things to pursue. If it wasn't for this accident, I would really like to take you to see, but Let's talk about it next time. "Maxim slapped him on the shoulder with a hearty smile, and then swaggered off.

The delay in ignition of the Helios fusion reactor did not affect the peace of St. Petersburg. Even Pravda, the authoritative newspaper representing the official mouthpiece, has only made a slight mention at the end of the page. For various reasons, such as the convening of the IMU conference, the visits of scholars from various countries and so on, the ignition plan originally scheduled to start at the beginning of the month will be postponed for one week.

However, even for the delay of the ignition plan, Russian officials have only taken it lightly. However, many people with a keen sense of political sense can still smell an unusual smell from a series of clues, such as "the president of the three Baltic States who visited in advance to return home", "the manager of the St. Petersburg branch of unified power company was arrested for taking bribes" and so on.

It's like an invisible storm brewing over St. Petersburg and even the entire Russian power system

On the afternoon of Maxim's departure from the clincia Hotel, scholars from all over the world began to arrive at the five-star hotel, which has almost been vacated for the International Conference of mathematicians.

In fact, as early as yesterday, many people have arrived here.

For example, Lu Zhou's tutor in Princeton, Professor deline, and Professor feverman, who once worked with him on the NS equation, and Professor fortings, who is said to be planning to make a big news before retiring.

And this, land boat also knows when breakfast.

However, compared with those old friends such as deline and Professor feverman, it was the figure standing in the lobby of the hotel carrying the suitcase that really made the mood of the land boat fluctuate obviously.

The silk like blonde hair is tied into a long ponytail at the back of the head, which is as dazzling as the floating light on the snow in winter under the background of the white long skirt. The thin shoulders and body lines look a little fuller than four years ago, but somehow, the feeling that people can't rest assured is more concerned than four years ago.

She was coming out of the cafeteria, walking through the lobby to the elevator, and recognized her at a glance.

And it seems that he felt his vision, holding the suitcase and standing in the middle of the hotel lobby, Vera also saw the familiar figure from the crowd.

"Professor..."

A little cry, that sapphire like pupil in an instant write a touch of surprise and surprise.

Her right hand released the handle of the trunk towbar, leaving the trunk in place, she trotted all the way to the direction of the landing boat.

According to the principle of inertia in Newtonian mechanics, if she doesn't slow down and move on at this time, she will probably collide with the ship in the next action.

However, this kind of unusual action is a little too exciting for a girl.

Under the influence of a series of physiological functions, such as shame and tension, with the distance between her and the land boat getting closer and closer, the pace of galloping is still as slow as pouring lead.

Standing in front of the boat, Vera, who was flushed with red cheeks because of running or something, reached out and smoothed her hair quickly. She said with a coy expression.

“…… Long time no see. "

"I haven't seen you for a long time," Lu said with a smile as he looked at the familiar face

"Well I'm fine. Don't worry about me. "

Although I got a positive reply, I didn't know why I suddenly dodged the eyes, but I couldn't let the boat down.

Just as Lu zhouzheng was about to ask questions, the sound of high-heeled shoes stepping on the granite floor came from the side.

"You make people more worried."

The two men looked to the other side. They saw Molina, who had picked up Vera's suitcase in one hand and carried her own suitcase in the other, and had already come to their side.

Because I saw it in Jinling last year, compared with Vera, Molina's feeling of land boat didn't change much.

If there is any change, it's probably that long windbreaker, which keeps warm, has been replaced by a short grey green coat.

A little boyish short hair over the ears, combined with the striped white shirt and khaki trousers, gives a feeling of being on the streets of Paris in the last century.

Hearing Molina's words, Vera hesitated a little and whispered.

"Eh? Do you have one? "

"I think if you have any questions, it's better to say them. Someone is a famous escort, and you are his precious apprentice. He must be able to find a way to help you out. "

"No, I'm really OK Please don't worry about me. "

It seems that she felt the pressure from Molina's questioning. Vera, who took over the handle of the suitcase towbar from her hand, said a thank you in a low voice. Then she took the suitcase and walked quickly to the direction of the elevator, even forgot to say goodbye to the boat.

Looking at the back of Vera walking to the elevator, Lu Zhou pulls a hand of Molina beside her and asks earnestly."Aren't you her teammate? Don't you know anything about her? "

"Obviously, my teammates didn't fully open up to me. What's more, even if I knew, without her permission, do you think I would tell you the privacy of a lady?"

Turning a white eye toward the landing boat, Molina pulled her sleeve back and quickly ran after the elevator with her suitcase.

Looking at the direction of the elevator with complicated expression, the land boat fell into silence.

Just at this time, another familiar voice with some joy came from the side.

"Professor!"

Attracted by the sound, Lu Zhou turned his head at once, and saw a young man with a dark complexion and curly hair, holding the arm of a Latino beauty with the same dark complexion and flowing long hair, greeting him warmly with his free right hand.

Seeing that Lu Zhou didn't seem to respond, the guy continued to shout as if he was afraid that he would forget himself.

"Hey, Professor! I'm hardy! Don't you forget me

"Of course I know it's you, just need a little time to digest this huge information..."

The line of sight swam back and forth between hardy and the beauty who greeted him. The boat opened its mouth, and it took a long time to say, "you all Married? "

With a bright smile and neat white teeth on his face, hardy felt the back of his head embarrassed and said with a smile, "of course! Anyway, I've graduated from the Ph.D. program for so many years, and I'm not young. Besides, I'm a professor now. It's pathetic not to get married again. "

Lu Zhou: "..."

This guy, as always, likes to add an extra sentence after a sentence that has nothing wrong.

Sure enough, he shouldn't have graduated so early.

It seems that he is aware of the inadequacy in Lu Zhou's eyes. After chatting with him modestly, hardy takes his newly married wife to the elevator.

According to him, they got married two months ago, and this time in St. Petersburg, in addition to attending the IMU conference, another thing is to spend their honeymoon.

The reason why we choose to arrange the honeymoon together with the IMU conference is that if we apply to the school in the name of attending the IMU conference, the school will not only allow paid leave and reimbursement of road expenses, but also give them a certain amount of travel subsidies

After attending the IMU conference, they will fly to Italy and Greece in the name of connecting flights.

Among all the people we know, hardy seems to be the only one who can do this kind of operation

Besides Hardy, in the lobby of the hotel, Lu Zhou also met Qin Yue.

Compared with four years ago, the change of this young man can be said to be from the inside out and earth shaking.

I remember when I first came to Princeton, this young man was a very honest and dull man. Now he not only treats people but also talks, which gives a very reliable feeling.

Seeing that their students are getting better and better, the heart of Lu Zhou is naturally quite happy.

The only thing that makes him a little bit frustrated is that Vera still refuses to confess to herself. What's wrong with her body

I hope, as she said, it's not a big problem.

But Lu Zhou always felt that things were not as simple as he thought
