Princeton Institute of Advanced Studies, Dean's Office.

The cleaned female worker wiped the dust on the glass window after pouring the water on the sill of the window sill.

After doing all the work with her hands and feet, she lifted the bucket and walked outside the office.

Before leaving, she looked at Professor Peter Sanak, who was sitting behind her desk, with some surprise.

Although she didn't know much about academic things, for the first time, she saw that the old man, who was always serious, showed a distressed expression in front of people.

Of course, although he took the post of dean, it was only five or six years ago...

Sitting at the desk for a while, the old man with white hair pushed the glasses on his nose and looked at the young man standing at the desk and sighed softly.

“At the beginning of this year, it was proposed to include you in the team of lifelong researchers at the Princeton Institute of Advanced Studies. I know that it is not a good time to say this now, but... are you really thinking about it?”

Each research institute at the Princeton Institute of Advanced Studies has a small, life-long research team. The scholars who make up this team are the best scholars in the world, and the research they undertake is also the most advanced research in all fields.

In academia, the status of a lifelong researcher at the Princeton Institute of Advanced Studies means not only the guarantee of research funding and living standards, but also the highest honor.

At present, there are only ten ten-year life research fellows in the School of Mathematics. One of them is Professor Pierre De Ligne, a mentor of Lu Zhou. If you stay here, it may be this year if you are fast, or two or three years if you are slow.

but……

Lu Zhou shook his head and said softly.

"I have considered it for half a year."

Before winning the Nobel Prize, his resources in the country were far less than those of Princeton. After winning the Nobel Prize, the resources he could get at Princeton were far from what he could get at home. Support can be compared.

There is nothing wrong with saying that he is selfish. After all, when he is doing multiple-choice questions, he really considers the problem with the "best choice" as the starting point.

After listening to Lu Zhou, the Dean Peter Goddard did not say anything more. He opened the drawer and took out an application form from it.

"Yes? Since you have already considered it, then I have nothing to say. Serve the country and serve the world... This is the Princeton's school motto. I think your choice is correct."

Putting this application form on the desk gently, Dean Peter Goddard seemed to put down the burden and rested relaxed on the chair, watching Lu Zhou continue.

"In addition to the position of researcher at the Princeton Institute of Advanced Studies, there are also faculty members at Princeton University... I guess you should be resigning when you return this time."

Lu Zhou: "Yes, I will go to Nassau Hall in a while."

Dean Goddard smiled and said: "Remember to say hello to Professor Isbrod for me."

Picking up the application form from the table, Lu Zhou nodded slightly.

"I will."

After leaving the office of Dean Goddard, Lu Zhou did not have too much stop at the Institute of Advanced Studies and went straight to Nassau Hall at Princeton University.

Compared with the disappointment of Dean Goddard, President Isbrod’s reaction was fairly mild, or calm.

After listening to Lu Zhou’s willingness to resign, he did not say much, and took out a form with similar specifications from the drawer.

"...I remember more than twenty years ago, when I was the Academic Director. Mr. Faltins found me and told me that he was going back to Germany. I have also retained him, but now I think, actually No need for this. This choice can be made in a day or two, and it can't be changed in a few words."

Pushing the glasses, he handed the form to Lu Zhou’s hand.

"It is our loss to be able to keep you."

Speaking of this, President Iscrob paused for a moment and continued in a joking tone. "So, in order to make up for our losses, I hope that you can at least accept the title of honorary professor while resigning as a professor."

After taking the application form, Lu Zhou slammed down and immediately laughed: "This is my honor."

......

When I first left Nassau Hall, it was already at dusk.

I left here with two application forms. On the way home, Lu Zhou walked very slowly, even a little around the road.

This kind of mentality is probably like a person who is going to travel far away. I want to spend more time in the places I have lived in in the past.

After all, I have lived here for so long, and I have experienced so many things. He still has a lot of feelings for Princeton.

When passing by Carnegie Lake, when Lu Zhou thought about whether to run for a while in the past, he accidentally saw a familiar figure sitting on a bench by the lake.

The corner of his mouth smirked. He walked over to the vending machine, bought a can of sports drink and a can of coffee, and walked toward the lake.

When he was close, Molina, wearing a blue sportswear, was wiping the sweat on her face with a towel.

Suddenly, a can of drink appeared in her sight.

Slightly squatting, Molina looked sideways to the side and saw that Lu Zhou was standing there.

The delicate eyebrows picked and picked, and she took the drink unceremoniously. After throwing a "thank you", she buckled the pull ring of the can, and poured a sip on her head.

"You're welcome."

Lu Zhou smiled and sat on the other side of the bench, buckled the pull ring of the coffee pot, and took a sip.

Although he still likes to drink instant coffee, the canned espresso coffee produced in this factory also has a flavor.

Molina: "When are you coming back?"

"It’s just arrived at noon. I originally planned to leave some time to run, and after I finished the matter, I didn’t realize that it was getting dark.” Looking at the students running late at the lake, and the lake. The canoeing team of the training team, Lu Zhou said in a chattering tone.

Molina looked at Lu Zhou.

"It’s half a year since you were not on Princeton."

"Yeah, time flies," looked at the sparkling lake in the sunset. Lu Zhou smiled and said, "Sometimes I will have the illusion that I just graduated yesterday, but I have been 25 years old since I came back." It is."

Molina: "...I think most people just graduated at the age of 25."

Lu Zhou was embarrassed and smiled. "It seems to make sense to say this... What do you say about it? How about your topic with your tutor?"

Molina’s mouth evoked a smug smile: “I have graduated and is now a lecturer at Princeton University.”

Lu Zhou glanced at her with a slight surprise: "I have graduated? Congratulations... Although I want to help you open a party to celebrate new colleagues, I have resigned now."

"Is it."

Molina’s expression was not unexpected, as if she had guessed it.

Looking at the can of drink in her hand, she continued, "So this can, is it my own?"

"That's right. Although a can of drink may not be enough," Lu Zhou patted the dust on his trouser legs and stood up from the bench, watching her smile and said, "When you have a chance, you will come to China for a tour." I will ask you to drink again."

Molina joked: "If there is no chance?"

"That may only be waiting for some day to meet at the academic conference."

When I used to run in the evening, the communication between the two was basically the same.

It started without any warning and ended without any warning.

Looking at the back of Lu Zhou, Molina did not say anything, picked up a stone and threw it into the lake.

In addition to mathematics, she has no other things of interest, and Lu Zhou can only be regarded as a general friend.

However, thinking of this guy is not here, how much still makes her feel lonely...
