I haven't seen you for a long time, and when you meet again in a foreign country, it's inevitable that there will be a lot of words.

While eating and chatting, the meal was eaten from twelve o'clock to more than two o'clock unconsciously.

After settling the bill, the three of them walked to the door.

Before saying goodbye, Lu Zhou looked at Chen Yushan and said sincerely: "I'm really embarrassed this time...... I'll wait until I get my driver's license another day and come to Philadelphia for dinner. ”

Chen Yushan's eyes lit up, and she immediately said, "Then it's okay, I can remember this meal!" ”

It seems that the senior sister is still a little worried about hanging herself at the airport for a long time.

Lu Zhou patted his chest and said, "Don't worry, what I promised, I will definitely not release your pigeon!" ”

The group said goodbye, Chen Yushan returned to the University of Pennsylvania, and Lu Zhou got into Brother Luo's car and went to Princeton, a small town located between Philadelphia and New York.

Sitting in the car, Lu Zhou fastened his seat belt and asked casually.

"How's the conditions over there?"

Senior Brother Luo said while driving, "What are you asking?" ”

Lu Zhou thought for a while and said, "For example, the dormitory? ”

Senior Brother Luo: "Dormitory? There are good and bad, but you don't have to worry, math and physics are at the top of the chain of disdain for Princeton's disciplines, and you are enrolled as a joint program between Kim University and General University, and you will probably be assigned a single room there. But let's be honest...... Personally, I find it interesting to have a quadruple room with two bedrooms. ”

Lu Zhou: "Won't it be troublesome?" ”

Senior Brother Luo smiled and said, "Actually, it's okay, it's also interesting to make friends with people from different countries, and the most important thing is that the dormitory will not be deserted." And in addition to being lively, the quadruple room has a large living room, and you can have a party on weekends. My ex-girlfriend and I met at a weekend party for international students. ”

Boisterous?

That's still it.

Lu Zhou smiled.

If he had a choice, he would prefer a quieter place.

Along the way, Senior Brother Luo talked to him about Princeton's campus scene, but as he talked, the topic somehow drifted to his previous girlfriends.

With an embarrassed but polite smile on his face, Lu Zhou listened to him quietly.

Just when he was about to fall asleep, Senior Brother Luo finally stopped telling his relationship history and parked the car on the side of the road.

"Here we are."

Lu Zhou, who was almost asleep, looked out the window and saw the familiar building.

Before I knew it, I had arrived at my destination.

After getting out of the car, Senior Brother Luo helped Lu Zhou drag the suitcase out of the back of the car and said casually.

"I'll take you through the formalities, I guess you haven't had time to visit Princeton last time you were here. You might get lost your way here for the first time, but every year I meet new students who ask for directions. ”

Lu Zhou nodded and said, "Then I'll trouble you." ”

Indeed, the last time he came to Princeton, he spent most of his time in a ten-square-meter hotel, delving into the twin prime conjecture. By the time he turned this conjecture into a theorem, the five-day academic conference had already ended, and he was soon on a flight back home.

Senior Brother Luo grinned: "What's the trouble, everyone is their own people, and it is appropriate to help each other outside." ”

With that, he took Lu Zhou and walked in the direction of the administrative building.

……

As one of several universities in the colonial period of the United States, Princeton University is influenced by British universities in both academic style and campus layout, with a kind of Oxfordian old-fashionedness.

This kind of old-fashioned is like two bronze statues of tigers in front of Nassau Hall, asserting themselves in this ever-changing world.

Although most of the elites who graduate from here will meet at an investment bank on Wall Street, it has to be said that this is indeed the farthest place from Vanity Fair among the Ivy League schools.

brought Lu Zhou to Nassau Hall, Senior Brother Luo did not accompany Lu Zhou in, but stood outside waiting for him, looking at the suitcase for him.

Walking into this historic administrative building with his own materials, Lu Zhou quickly found the place to register for school according to the instructions on the brochure and the door number on the side of the corridor.

Sitting in the office was a Latin American woman in her thirties, with a slightly darker complexion and a ponytail, and judging by her dress, she probably looked like an assistant or something.

It may be that someone came here to say hello in advance and told this lady that a Chinese student would come to report today, so she just glanced at Lu Zhou and said formulaically.

"Do you have the materials?"

"It's all here." Lu Zhou handed over the materials in his hand.

The lady checked the materials and made sure there were no problems, then opened the drawer at hand.

"Your student registration has been registered, this is your student ID card and the dormitory key, with the door number plate written on it, remember to keep it safe. In addition, your dormitory is ...... in this location," he said, drawing a circle on the map of the freshman handbook with a ballpoint pen, and the lady returned the freshman handbook to Lu Zhou's hand, smiling slightly, "I wish you a happy study life." ”

That's it?

Lu Zhou blinked and looked at her.

Noticing the inquiry in her gaze, she asked, "Is there anything else?" ”

Lu Zhou glanced at the only key and student ID card in his hand, and asked, "Where is my tutor?" ”

"It's up to you to choose," the lady looked at Lu Zhou and continued, "Most people decide on their doctoral supervisor before entering the university, but your situation is a bit special. My advice is that you have the opportunity to sit in on a few classes and choose a tutor who suits you and start your studies...... Of course, the premise is that the other party also has time, and preferably as soon as possible. ”

Meaning, go to the interview yourself?

Lu Zhou thought that the school had already appointed him.

But that's fine.

If you arrange a random tutor, you will find that you can't get along in the end, and it will be very troublesome.

After coming out of the administrative building, Senior Brother Luo immediately walked over to him.

"Done?"

"Sort of."

"Who is your mentor?"

"Haven't thought about it yet......"

"Haven't thought about it yet?" Senior Brother Luo looked at him in surprise and said unexpectedly, "I thought you had already thought about this issue during the Chinese New Year. ”

Lu Zhou coughed lightly and said, "There were a lot of things during the New Year, so I didn't come over...... Can you recommend me? ”

Senior Brother Luo thought for a while and said, "If you recommend it...... If you're going to jump into the math physics hole, I'm of course the first to recommend my boss, Edward Witten. If you're planning to focus on number theory or algebraic geometry, Drinje is a good choice. If you had been here a few years earlier, you could have even studied under Andrew Wiles, the proover of Fermat's theorem, but sadly, he returned to his alma mater, Oxford, to teach at his alma mater in 11 years. and Faltins, the proover of Modell's conjecture, also because of the great masters in the field of algebraic geometry and number theory......"

It seems that in addition to his ex-girlfriend, this senior brother still has something in his stomach.

Although I hadn't worked with him, it was impossible to think that I could do a PhD under Edward Witten.

After listening to his suggestion, Lu Zhou thought seriously for a moment and nodded: "I'll think about it." ”

Senior Brother Luo smiled and said, "Do you need me to take you to the dormitory?" ”

Lu Zhou: "No need, according to the map, I think I can find the location, just send me here." ”

"OK, remember to call me if you have something."

"Well, definitely!"

After separating from Senior Brother Luo, Lu Zhou followed the route on the map and walked in the direction of the dormitory building.

His residence hall is located in a quiet corner of the Princeton campus, not far from the Institute for Advanced Study.

With his excellent sense of direction, Lu Zhou easily found this place.

Although he had already seen the photos of this dormitory building in the freshman handbook, he was more or less prepared in his heart. But when he saw this dormitory building in reality, he was still surprised.

It's really ......

It's so retro!

It is said that this colonial-style British building is more than 90 years old, and the older ones can almost apply for museums. Although it has been renovated several times, the building has largely remained in its original appearance.

In particular, the dark red brick wall and the dark green vines on the wall look like an old mansion.

Isn't it really haunted?

With such a question, Lu Zhou walked in.

When he walked up to the second floor with his suitcase, he looked up and saw a figure standing abruptly on the stairs.

Because the light on the stairs was not good, and Lu Zhou had just come in from a bright place, Lu Zhou couldn't see her face clearly, but judging from the silhouette of her body and skirt, she was probably a lady.

The man who brushed the long hair from his ears and crossed his arms smiled at him.

"You're finally here."

Seeing that the man opened his mouth to speak to himself, and he was still very familiar with his own tone, Lu Zhou was suddenly shocked.

Hold the grass!

What the hell?
