Dingdong—

Pang Xuelin picked up his phone, looked at Qi Xin's reply, and couldn't help but be slightly stunned.

The tone of this reply seemed to be different from Qi Xin's past speech.

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

Could it be that she is looking for a boyfriend?

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

The Witherspoon Steakhouse on Nassau Street is not far from the hotel where Pang Xuelin is staying. Pang Xuelin went downstairs at 6:30 and walked to the steakhouse at 6:40.

Qi Xin hasn't arrived yet.

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

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

Her coat was not buttoned, and there was a versatile knee-length skirt inside. Black stockings wrapped around her slender calves, looking elegant and elegant.

Having not seen each other for half a year, Qi Xin looked much thinner and haggard, but when she saw Pang Xuelin, her eyes seemed to have instantly returned to her former glory.

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

A bright smile appeared on Qi Xin's face and he couldn't help but speed up his pace.

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

Behind Qi Xin, a tall mature woman was followed. Although her appearance was a little inferior to Qi Xin, the charm between her eyebrows was far beyond that.

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

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

Pang Xuelin was stunned.

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

Qi Xin sat down opposite Pang Xuelin and said with a smile.

Pang Xuelin came to his senses and smiled and said, "Qi Xin, why did he get divorced after only half a year? You should call me junior,

"Then... OK! Junior!"

Seeing that Pang Xuelin's attitude towards him was no different from before, for some reason, Qi Xin felt a little happy inexplicably.

"Is this one..."

Pang Xuelin turned his gaze to Zhizi sitting next to Qi Xin.

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

"Hello, Professor Pang!"

Zhizi blinked at Pang Xuelin and said with a smile.

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

"Hello, Wang Zhi!"

Pang Xuelin glared at Zhizi, shook hands with her, then handed the menu to the two of them, and said, "I ordered a fried salmon with herb sauce, a fried butter shrimp, a fried sirloin steak, and a creamy mushroom soup. What do you want to eat, add some more!"

Qi Xin took the menu and said, "I'll add another tuna salad, a tomahawk steak and borscht, Sister Zhi, where are you?"

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

"good!"

Soon, Qi Xin recruited a waiter and handed the ordered menu to the other party.

Pang Xuelin asked: "Senior sister, how did you feel during this time when you came to Princeton?"

Qi Xin said: "It's okay, but the study pressure is a bit too high. I have to read various documents every day and write several articles every week for group discussions. In addition, I have to help professors with projects, and I often get so busy that I don't have a business school. But I'm a little surprised. Why doesn't Princeton set up a business school? I'm studying finance and economics now and feel more academic."

Pang Xuelin smiled and said, "Princeton not only has no business school, but also no law school and medical school. This is to maintain theoretical tendencies for its academic style and maintain the simplicity of the school. This feature is incomparable to other Ivy League schools or other recently emerging prestigious schools."

Qi Xin nodded and said, "That's true. The classmates around me are very hard-working. After I entered school, I didn't dare to relax at all. I felt that if I relaxed a little, I might fall behind."

Pang Xuelin laughed and said, "This is a rare opportunity. When you graduate, you will miss this hard-working day."

Qi Xin smiled and nodded.

At this time, Tomoko on the side said, "Professor Pang, I am now studying for a graduate school under Professor Peter Sanek. I heard that the Ponzi geometry seminar at Jiangda is still recruiting people. I want to go to your doctoral school. What do you think?"

Pang Xuelin was slightly stunned. He didn't expect that Zhizi would actually think of using this method to return to him.

If she goes to her own school, then she will not attract attention by handing over the graphene lithium air battery to her in the future.

He laughed and said, "Yes, but I have a high requirement for recruiting graduate students. Let's do this. If you prove the hail guess, I will agree to you to study for a doctorate under me!"

"Hail guess? Is this difficult?"

Qi Xin said curiously.

Pang Xuelin smiled and said, "The hail conjecture is also called the horn valley conjecture. It 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, the even factor 2 is precipitated. After several times, it finally returns to 1. This conjecture has been almost half a century since it was proposed, and no one in the mathematics community has been able to solve it yet."

"This is too difficult!"

Qi Xin opened her mouth and was about to ask for love for Zhizi, but Wang Zhi smiled and said, "Professor Pang, then I'll agree that if I solve the hail speculation, I'll go to your subordinates to study for a graduate school."

"A gentleman's words!"

"It's hard to chase after all!"

The two clapped in a tacit understanding.

Qi Xin looked at Pang Xuelin, then turned her head to look at Zhizi, always feeling something was wrong.

The set meals ordered by the three of them were quickly served. Next, Pang Xuelin, Qi Xin and Zhizi ate and chatted, and the atmosphere on the dining table was always very lively.

Half an hour later, Tomoko finished eating the last piece of fish steak, picked up a tissue and wiped her mouth, and smiled and said, "Okay, Professor Pang, I've finished eating, I won't bother you next. I wish you all a happy time!"

As he said that, Chiko didn't wait for Pang Xuelin and Qi Xin to react, so she got up and left the restaurant.

Pang Xuelin and Qi Xin couldn't help but look at each other, and Pang Xuelin smiled and said, "Your bestie, is quite interesting."

Qi Xin laughed and said, "Indeed, I have known Sister Zhi for less than a month, but I don't know what happened, so we became friends who can talk about everything."

Pang Xuelin secretly found it funny. With Zhizi's ability, he probably had already checked Qi Xin's details, and then deliberately approached the other party. It should not be too simple to get Qi Xin's friendship.

I just don’t know how the other party obtained the legal status of the United States, but I can still study for graduate school under Peter Sanak.

Pang Xuelin needs to ask carefully.
