9 p.m. Beijing time.

Sheraton presidential suite.

Standing next to the French window, Lu Zhou received a call from the other side of the Pacific Ocean.

"Your sister has arrived safely."

"OK, I see Thank you. "

"You're welcome," Qin Yue smiled at the other end of the phone. "By the way, she lives in a student apartment Or I'll give her your apartment. I'm planning to rent a smaller apartment near the school. "

When Lu Zhou left Princeton to return home, he gave Qin Yue the keys to the villa in the nearby town and the Ford Mustang, and asked him to pay a property tax for himself every year.

After all, the older the house is, the longer it is unoccupied, the less it can live. Especially in the northern state of New Jersey, if there is no one left in the house in winter, it is easy to have the water pipe crack and collapse the roof.

Although I don't think I'll have a chance to go back and have a look, the house and the fireplace inside, and the land boat are still very fond of it.

Lu Zhou shook his head and said, "no, I mentioned it to her at this time of the new year. She refused without even thinking about it. Later, I also thought about it. It's not downtown. I'm not sure if she lives in such a big house as a girl. If you don't want to live, ask vera or other professors in Prince for me if they are interested. "

In fact, for Xiao Tong's idea, Lu Zhou can feel it in her heart.

On the one hand, she is very grateful for the fact that she has been opening her wings to protect her from the wind and rain since childhood, and also relies on this feeling. On the other hand, her character is very similar to her. She is the type who is not willing to cause trouble for others, eager to be able to live an independent life, eager to be able to one day no longer rely on herself, no longer a small burden of her own, or even help in turn I'm busy

In fact, what Lu Zhou wants to say is that he doesn't mind being dependent on her, let alone taking such dependence as a burden.

After all, they are family.

And the relationship between family members, itself is maintained in a kind of mutual dependence

Qin Yue smiled and said, "I didn't say I'm not going to live. I can rent such a big house for 3000 dollars a year. This kind of good thing can't be found all over North America. I just said if your sister needs it, I'll find the house myself. But it's true that it's not convenient for her to live in such a remote place. "

Although Princeton's student apartments are low-cost, they are better near the campus facilities and secure. Xiaotong's Qinyue apartment seems to be a two person apartment. If there is a roommate, he can integrate into campus life faster.

After simply asking Xiaotong about her situation over there, Lu Zhou put her affairs aside and chatted with her former students.

"How is it? Are you still used to life there? "

Qin Yue smiled and replied, "I've always been used to it. It's enough for me to have a place to concentrate on my research. The only thing you are not used to is that you are not here, and you can 't get lessons from you when you meet difficulties. "

Lu Zhou: "you are already a professor. You want to learn from me. It's time to think about it. In other words, what are you working on recently? "

"The Hualin problem in additive number theory When it comes to this, Qin Yue can't help sighing, "this thing thinks of my big head every day! Sometimes I think it makes sense that there are few people studying number theory. You often encounter a problem that seems to be a pure stack of prime numbers, but it turns out to be an algebraic geometry problem after deep research. However, the method of algebraic geometry can not solve the problem of polarized light. Finally, representation theory, p-adic theory and so on have to be introduced Of course, it also includes your group construction. "

"It's actually a good thing," Lu said with a smile. "Isn't that how our science has progressed?"

Qin Yue was helpless and said, "that's right, but it's not very friendly for people who study these issues. Sometimes I can't help but think that if there is a way to quickly get the qualitative meaning of the problem we want to solve with what method can we solve it... "

Lu Zhou: "I'm afraid it's not a category of mathematics. It's a category of metaphysics."

Qin Yue: "maybe."

When the topic came here, there was a sudden silence.

After chatting for such a long time, Qin Yue always felt that there was something Lu Zhou wanted to say, but maybe he didn't know how to say it, so he was circling around with him all the time.

When he hesitated to take the initiative to break this point, the silent boat suddenly spoke abruptly.

"Vera she How are you? "

Not surprisingly, Qin Yue said secretly that it was true, and then sighed.

"I asked for you, but I didn't find anything useful She is not very willing to say her own situation, and I don't know if she found out anything, she now intends to hide from me. Later, I tried to ask the lecturer Molina who studied Riemann's conjecture with her, but she didn't want to talk too much about it. "Hearing this, the boat was silent for a while.

“…… Thank you. I see. "

After a pause, he continued.

"If she's really not going to say anything, don't force her."

Qin Yue: "are you going to hang up?"

"Well, if it's nothing." Looking at the wall clock, Lu Zhou continued, "after all, it's not too early for me."

After hesitating for a moment, Qin Yue asked, "may I ask you a question? What I really wanted to ask before was about -- "

land boat:" If it's an academic question, just ask. "

Qin Yue, who was interrupted, sighed softly and said, "forget it, I still don't ask..."

……

Sitting in the next room, Wang Peng, who has just shaved, is sitting beside the bed, checking the equipment in the lower trunk according to the Convention.

Just then, there was a faint sound of footsteps in the corridor outside the door.

From the sound of footsteps, he could tell who was coming. He stood up and walked to the porch after throwing the equipment back into the trunk. Almost as soon as there was a knock on the door, he grasped the handle and opened it.

"What is it?"

Standing at the door, the boat said casually.

"Drink? It's my treat. "

From the expression on Lu Zhou's face, Wang Peng seemed to see something. After a few seconds of silence, Wang Peng said, "you can only smoke at work and not drink, but if you want to drink, I can accompany you."

"What kind of company?"

Wang Peng replied straightforwardly, "look around and carry you back when you are drunk."

Lu Zhou shook his head with a smile.

"Drunk? I? Come on... "

Looking at the boat turning to the elevator, Wang Peng didn't say much. He closed the door, followed him to the elevator, and even reached for him to press the button on the floor where the bar is.

Seeing this, Lu Zhou took a look at him and said nothing.

I didn't say a word all the way. I went to the boat in front of the bar and sat on a high footed stool. Then I looked at the bartender behind the bar and said.

"A whisky and water."

"Just a moment."

Looking at the bartender's shaking hand like a unicorn's arm, Wang Peng vaguely predicted that Lu Zhou would drink a lot tonight, so after a moment of silence, he reminded him.

"Tomorrow is the unveiling ceremony. I suggest you drink less."

As a result, what he didn't expect was that Lu Zhou, who had always listened to people's advice, this time changed its normal.

"Leave it alone."

He took the cup from the bartender's hand and rudely dropped the boat with such a sentence. Without saying a word, he drank it one by one.

When did the boat stop? I can't remember it very well.

When he came back to his senses, it was the next morning
