Chapter 136

When Gu Lu walked out of the school gate with a cardboard box, he saw a familiar shadow at the school gate.

Su Xi also found Gu Lu, and walked over with a small smile, "Teacher Gu, good morning!"

"Long time no see. Gu Lu responded.

Su Xi had a sweet smile on his face, "Yes, the affairs of foreign companies are a little troublesome, and it took me a lot of effort." But luckily, I've taken care of it and just came back yesterday. ”

Then, Su Xi noticed the cardboard box in Gu Lu's hand, "Are you going to ask for it...... Selling scrap?"

"......" Gu Lu was speechless, "I resigned, and here are some things in my office." ”

"Resign?" Su Xi frowned slightly, and then became surprised, "Gu Lu, you resigned!"

Gu Lu nodded, "Well, just now, I already resigned. ”

"That'...... Then you, are you interested in being my personal tutor?" Su Xi looked up at Gu Lu, turned his toes, grabbed the corners of his clothes with both hands, and stumbled to say this.

"Uh...... I have already agreed with Yenching University that I will teach at Yenching University. ”

"Oh, well. Su Xi's lost eyes flashed.

The plan has failed again!

Su Xi held his little hands behind his back, a pair of smart eyes scanned Gu Lu's face, and the skirt fluttered gently in the wind, "Gu Lu, I invite you to dinner now, you shouldn't refuse." ”

Gu Lu shook his head and smiled, "Of course not." But it wasn't you who invited me, I invited you, even if I thanked the casino for your help that time. ”

Su Xi pondered for a few seconds, "It's okay for you to treat you this time, but next time I'll invite you back." ”

"Remember, I owe you a meal!"

Gu Lu nodded, "Yes." ”

is about to part, one of the two is in Haicheng and the other is in Yanjing, and they don't know when they will meet next time.

simply, Gu Lu came all by Su Xi.

............

On September 3, Gu Lu flew to Yanjing.

First went to the small villa near Yan University, and Gu Lu visited the teacher Ji Changyi.

Seeing Gu Lulai, Ji Changyi was very happy.

didn't even say a few words of greeting, Gu Lu was pulled by Ji Changyi to fight three hundred rounds on the chessboard.

As a result, it is naturally still the same every time Ji Changyi wins Gu Lu with the advantage of half a son and one son.

"Boring, boring!" Ji Changyi stroked his beard and looked sulking, "Always let me do this, you are not bored." ”

"The students had a lot of fun. ”

"I think you're just idle and have nothing to do. Ji Changyi picked up the teacup and took a sip, "What have you been busy with lately?"

"I'm working with a senior brother in Princeton on the first problem of the minima-model program. Gu Lu replied honestly.

"Minimal model program?" Ji Changyi raised his eyebrows, "This thing is very unpopular!"

Gu Lu shrugged his shoulders and smiled, "I thought so at the beginning, but after studying for a while, I found that there are many misunderstandings about the rumors about the program of the minimum model in the mathematical community. ”

Gu Lu's words made Ji Changyi curious, "How do you say this?"

"The Minimalist Program is not as difficult as rumored by the outside world!" Gu Lu shook his head and expressed puzzlement, "When I was studying the Minima Model Program, the whole process was extremely smooth without the slightest hindrance. ”

"Even better than when I first worked on the Cohen-Lenstra conjecture. I really don't understand it, it's really three people into a tiger, and the outside world has obviously exaggerated the difficulty of the research of the minimalist program. ”

Ji Changyi stroked his beard and said in a calm tone, "It shouldn't be possible." Although the direction of the minimalist program is unpopular, there are at least hundreds of mathematicians working in this direction. There's no way they're lying. The minimalist program is indeed a very difficult direction to study!"

"As for your words...... Ji Changyi turned his head and glanced at Gu Lu and spoke, "I haven't asked yet, how far has your research progressed?"

Gu Lu replied, "At present, it is almost 80% completed." ”

"It's pretty fast. Ji Changyi muttered, then stretched out his hand, "Show it to me." ”

Gu Lu took out his mobile phone, opened a document, and handed it to Ji Changyi, "Oh, teacher, this is it, at present, we have reached the final stage of proving the existence of the Calabi-Yau cluster flip operation." ”

"Let me see. Ji Changyi put on reading glasses and looked at the lines of formulas.

One minute, two minutes...... Thirty minutes, forty minutes......

After a full hour, Ji Changyi took off his reading glasses and rubbed his somewhat swollen eyebrows.

"Teacher, are you okay?" asked Gu Lu with concern.

"I'm fine. Ji Changyi waved his hand, signaling Gu Lu not to worry, and then smiled bitterly, "People, I still have to serve the old, a few years ago, I didn't have anything to do with reading papers for six or seven hours in a row, but now I can't!"

"But to my relief, my students have all grown up!" Ji Changyi's eyes were full of relief when he looked at Gu Lu, "Gu Lu, didn't you just wonder why you think that the minimalist program is not as difficult as rumored?"

Gu Lu nodded, "Well, yes." ”

Ji Changyi laughed, "Actually, it's not that the rumors are false, it's just because you haven't realized that your math level has improved a lot compared to before!"

"The Miniatures program may be an almost difficult mountain for you who just graduated a year ago. But now, for you, it's just that. ”

"Haha, I didn't expect that in just one year, Gu Lu, you have made such rapid progress, and in a few years, you can become the only presence in the international community of Chinese mathematics like several of your senior brothers. ”

Ji Changyi's face was ruddy, and his tone was full of joy.

"Hey, I guess it's because Gu Lu stayed in high school to teach this year. Otherwise, you should not come to Yanda and continue to go back to your high school to teach math and do the math!"

Gu Lu: "......"

Gu Lu sneered, "Teacher, forget it, Haicheng is quite far away, and it will cost a lot of money to go back to the plane ticket alone." ”

"I'm kidding you, I'm willing to let you really go back. For a talent like you, staying in high school as a teacher is burying talent. Ji Changyi stood up with the armrest of his chair, "When you went back to Yan University to teach, I already greeted your senior brother. ”

"What did Senior Brother Bao say?"

"Your senior brother is naturally happy that you can go back to school, and he has already made arrangements, and when you go to school, you can go directly to him. ”

"However, with your resume, it is not enough to be directly promoted to associate professor, so you can only start as a lecturer. Ji Changyi explained the situation to Gu Lu.

Gu Lu had already expected, "The lecturer is good, teacher, don't worry, I will definitely work hard in Yan University next, and within two years, I will strive to get a professor's title back!"

"You kid is very ambitious!" From lecturer to professor in two years, Ji Changyi knows the difficulty.

Gu Lu smiled very easily, "Several of your disciples, except for me, are all professors, no matter what you say, I can't embarrass you." ”
