"How about it, let's go work in my company!", when he was about to leave, Simmons sent out an invitation again, through this contact, he admired Lu Qiujian's mathematical talent, "My Renaissance company can provide you with a broad enough platform!"

"I still prefer to do research!", Lu Qiujian politely rejected him again, but he didn't say anything to death, "Of course, if I need your help in the future, I will definitely contact you!", it doesn't seem to hurt to know a Wall Street celebrity, Jason is still much more tender than him!

"My phone is open for you 24 hours a day!" Simmons' Renaissance is also unique on Wall Street, and among his 150 employees, there are never any Wall Street analysts, MBAs, or PhDs in finance, but rather PhDs in mathematics and natural sciences.

"Thank you!", Lu Qiujian watched him board the private jet, turned around and hugged Natalie gently, "Nat, don't be sad, I'm not going to an alien planet, if you want, you can go to Huaguo to see me in the summer vacation!"

"You were on vacation during my summer vacation, why don't you stay in the United States for a while!", Natalie's eyes were full of anticipation, "We can hike like we did in the past few days, go to the Pacific Ridge Trail, go to the Continental Divide Trail"

The sooner this event is carried out, the better it is for him, and only after this matter is over can he have time for other research, and by the way, he shook his head apologetically, "You know, I haven't been home for almost another year, and my family misses me too!"

"Okay, I'll find a way to find you then!", Natalie smiled at the corners of her mouth, and although she was a little reluctant, she didn't want to make the parting bleak.

After sending off another person, Lu Qiujian boarded the flight back to New York alone, got off the plane and hailed a taxi, and returned to Princeton in the evening.

I went out on a trip and was delayed for several days, and then it was time for the exam, so Princeton should not be able to ask for a report meeting, right? Lu Qiujian thought happily.

"Hey, man, you're back! Someone from the school's outreach department comes to harass him almost all day!", and as soon as he got back to the dormitory, Patrice complained to him!

"What did they say?Do they come here every day?", he threw his luggage on the floor, opened his bedroom and looked at it, well, it was quite clean, it seemed that Patrice had helped him get someone to clean it in the past two days.

"Keep asking me if you've come back, can you contact you or something!", he took the Arkansas specialty that Lu Qiujian threw over, unscrewed the lid and tasted it, and nodded with satisfaction, "Of course I said I couldn't help it! But the day before yesterday and yesterday suddenly didn't come, I don't know if I will come today!"

"Probably not!", according to the time, it will be too late anyway!

Sure enough, when Lu Qiujian returned to the classroom, he came up with his reason for preparing for the exam, and the other party immediately proposed that he could apply to the school for him to be exempted from the exam; unfortunately, Lu Qiujian firmly refused, and had no choice but to give up the plan to hold this report meeting.

The exam didn't require much energy for Lu Qiujian, and he even found time to update a few articles on arXiv during the exam, which greatly satisfied the mathematicians who had been looking forward to it for a long time during the trip.

"Man, are you leaving soon?", when the last exam was over, Patrice, who had always been very aggressive, also showed a reluctant look.

"yes, next season's NCAA Tigers can only rely on you!I'll follow your game online!", Patrice did not participate in this year's draft in the end, and the top pick still went to LeBron James, but when the reporter asked him if Lu Qiujian participated in the draft, he was still confident of getting the top pick, his expression was a little embarrassed.

"No problem, I'll help you clean up Yale!", he patted his chest and assured that after Lu Qiujian left, qualifying from the Ivy League has become the highest expectation of the Tigers.

"Are you going back?", Professor Nan's house, the two chatted while playing Go, "It's okay to go back, but don't relax yourself, and strive to make some pioneering achievements!"

"How's your contact?", Lu Qiujian quietly slaughtered one of Professor Nan's big dragons, "If only you could substitute for me next year!"

The corners of Professor Nan's mouth twitched, "I don't want to teach a child like you who doesn't understand anything about respecting teachers and teaching!"

I didn't see that it was still an old tsundere!"Hey, who made which of your big dragons have too ecstatic body, it really makes people want to eat it!"

"I'm going to refill a cup of tea!", the male professor leaned together, his knee just hit the chessboard with a slight turn, and the chess pieces were knocked into a mess, "Hey, I'm really careless, or this game should be a draw! It's a pity, I finally let out a few chess pieces to revitalize the situation, and I was about to clean you up, but it's gone!"

"It's okay! I remember the position of the chess pieces, why don't I rearrange them for you?"

"Hey, don't you give the teacher face at all, do you?", Professor Nan didn't have the slightest doubt that he could review it with his memory, "Go, go, hurry back and pack your things, and I'll clean you up when I go to Beijing Normal University next year!"

"Hehe, then I'll wait for you! I'll pick you up when you're back, please eat authentic Beijing snacks!", Lu Qiujian got up and left with a smile.

After leaving Professor South's house, he went to visit Wiles, Gowers, Thurston, Griffith, Dyson, and other professors who had helped and taught him throughout the year.

These people all felt sorry for Lu Qiujian's departure, and revealed the intention of retaining; Lu Qiujian was very grateful in his heart, but still politely refused.

"Professor Witten, I'm sorry for you about the letter of recommendation!", coming out of Edward Witten's home, Lu Qiujian's visit also came to an end, in addition to Witten, he also asked Dyson to write him a letter of recommendation, with the recommendation of these two people, presumably the supervisor who applied for a doctorate should not reject him, right?

After a night of bouncing out at a bar with Patrice and other Tigers, and the next day a celebration with Alforth and other math classmates, Luciu's time at Princeton was nearing its end.

After packing his bags, he threw the things he didn't need to Patrice, packed the rest, and after attending the final ceremony tomorrow, he would go to New York to board a flight back to China.
