The Science Fiction World of Xueba

Ding dong——

Pang Xuelin picked up the phone, looked at Qi Xin's reply, and couldn't help being slightly taken aback.

The tone of this reply seemed to be different from Qi Xin's way of speaking in the past.

And she also took the initiative to bring a friend to see her?

Could it be that she has found a boyfriend?

Pang Xuelin shook his head and didn't think about it.

The Witherspoon Steakhouse on Nassau Street is not far from the hotel where Pang Xuelin stayed. Pang Xuelin went downstairs at 6:30, and when he reached the steakhouse, it was only 6:40.

Qi Xin hasn't arrived yet.

Pang Xuelin found a four-person booth and sat down, and asked the waiter for three glasses of water.

About ten minutes later, Pang Xuelin saw Qi Xin walking in wearing a gray woolen coat.

Her coat was unbuttoned, and inside was a versatile knee-length skirt. Black stockings wrapped her slender calves, which looked elegant and elegant.

Not seeing each other for half a year, Qi Xin looked a lot thinner and haggard, but when he saw Pang Xuelin, his eyes seemed to regain their former brilliance in an instant.

Pang Xuelin waved to Qi Xin: "Qi Xin, I'm here!"

A bright smile bloomed on Qi Xin's face, and he involuntarily quickened his pace.

But in the next second, Pang Xuelin's eyes suddenly widened.

Behind Qi Xin was a tall, mature woman. In terms of appearance, although she was a bit inferior to Qi Xin, the charm between her eyebrows and eyes was far superior.

Not to mention, her figure is already close to perfection.

"Tomoko...how could she be with Qi Xin?"

Pang Xuelin was dumbfounded.

"Learn...Professor Pang, long time no see!"

Qi Xin sat down opposite Pang Xuelin and smiled.

Pang Xuelin came back to his senses, and said with a smile: "Qi Xin, why did you get married after not seeing each other for half a year? Why don't you call me junior?

"Then... alright! Junior!"

Seeing that Pang Xuelin's attitude towards him was the same as before, for some reason, Qi Xin felt a little happy for no reason.

"Who is this……?"

Pang Xuelin turned his gaze to Sophon who was sitting next to Qi Xin.

Qi Xin smiled and said, "By the way, let me introduce you, this is Wang Zhi, my best friend I met after I came to Princeton, and is now a master's student in the Department of Mathematics of Princeton University!"

"Professor Pang, hello!"

Sophon blinked at Pang Xuelin, and said with a smile.

Pang Xuelin felt a little headache, Zhizi actually appeared beside Qi Xin, and it seemed that she had obtained a legal status in the United States.

"Wang Zhi, hello!"

Pang Xuelin glared at Tomoko, shook hands with her, and then handed the menu to the two of them, saying: "I ordered a pan-fried salmon with herb sauce, a pan-fried butter prawn, and a grilled sirloin steak. A cream of mushroom soup, what do you want to eat, add more!"

Qi Xin took the menu and said, "Let me add another tuna salad, a tomahawk steak and borscht, sister Zhi, how about you?"

Tomoko smiled and said, "I'll have a cod steak and borscht!"

"good!"

Soon, Qi Xin called a waiter and handed over the ordered menu to him.

Pang Xuelin asked: "Senior sister, how do you feel during your time in Princeton?"

Qi Xin said: "It's okay, but the study pressure is a bit heavy. I have to read various documents every day, and I have to write several articles for group discussions every week. In addition, I have to help the professor with projects, and I am often very busy. But I’m a little surprised, why didn’t Princeton set up a business school? The finance and economics major I’m studying now feels more academic.”

Pang Xuelin said with a smile: "Princeton not only does not have a business school, but also a law school and a medical school. Rising prestigious schools are incomparable."

Qi Xin nodded and said, "That's true. The students around me are all very hardworking. After I entered school, I didn't dare to relax at all. I feel that if I relax a little, I may fall behind."

Pang Xuelin laughed and said, "This is a rare opportunity. After you graduate, you will miss this period of hard work."

Qi Xin smiled and nodded in agreement.

At this time, Sophon on the side said: "Professor Pang, I am currently studying under Professor Peter Sarneck. I heard that Jiang University's Ponzi Geometry Seminar is still recruiting people. I want to go to you to study for a Ph.D. how do you feel?"

Pang Xuelin was taken aback for a moment, but he didn't expect Sophon to come back to him in this way.

If she goes to study under her own hands, it won't be noticeable that she will hand over the graphene lithium-air battery to her in the future.

He laughed and said, "Yes, but I have relatively high requirements for recruiting graduate students. How about this, if you prove Hail's conjecture, I will allow you to study under me for a Ph.D.!"

"Hail conjecture? Is it hard?"

Qi Xin asked curiously.

Pang Xuelin said with a smile: "The hail conjecture is also known as the Kakutani conjecture, which refers to a positive integer x. If it is an odd number, multiply it by 3 and add 1. If it is an even number, then extract the even factor 2??. After several times, finally Back to 1. It has been almost half a century since this conjecture was proposed, and no one in the mathematics community has been able to solve it.”

"This is too difficult!"

Qi Xin opened his mouth, and was about to plead for Sophon, when Wang Zhi said with a smile: "Professor Pang, then it's settled, I'll go to graduate school under you after I solve the Hail conjecture."

"A gentleman's word!"

"A four-horse horse is hard to catch!"

The two clapped their hands tacitly.

Qi Xin looked at Pang Xuelin, then at Sophon, always feeling that something was wrong.

The set meals ordered by the three were served quickly. Next, Pang Xuelin, Qi Xin, and Tomoko ate and chatted, and the atmosphere at the table was always lively.

Half an hour later, Tomoko finished eating the last piece of fish fillet, wiped his mouth with a tissue, and said with a smile, "Okay, Professor Pang, I'm done eating, and I won't bother you from now on. I wish you a good time!"

Saying that, Sophon didn't wait for Pang Xuelin and Qi Xin's reaction, got up directly, and left the restaurant.

Pang Xuelin and Qi Xin couldn't help but looked at each other, Pang Xuelin said with a smile: "You are very interesting, girlfriend."

Qi Xin laughed and said, "Indeed, I have only known Sister Zhi for less than a month, but somehow, we have become friends who talk about everything."

Pang Xuelin secretly thought it was funny, with Tomoko's ability, he might have checked out Qi Xin's details long ago, and then deliberately approached him. If he wanted to gain Qi Xin's friendship, it shouldn't be too simple.

I just don't know how the other party obtained the legal status in the United States, and even went to graduate school under Peter Sarnak.

Pang Xuelin had to ask carefully.
