Chapter 775

November 27.

The first snow of winter arrived. Snowflakes fluttered, covering the eaves of red walls and green tiles, small paths of lake stones, and century-old ancient trees. The vermilion railings and dark tiles of the Shuchun Garden were shadowy in the wind and snow.

After finishing class, Xu Qingzhou came out of the lecture hall and went straight to the School of Mathematics.

This semester, he still opened the course on the Riemann Theorem.

With the passage of time, the number of tourists coming to his classroom to check in has decreased a lot, but with the blessing of the Nobel Prize and the Fields Medal, the stepped classroom is still overcrowded.

Song Yao called Song Lulu to come home for dinner. Just now Song Lulu sent a message saying she would go back to the dormitory and come over in 20 minutes. He just happened to go to Professor Gu's side to drink a cup of tea.

At the gate of the School of Mathematics, Xu Qingzhou stomped his feet, patted off the snow petals on his shoulders, and just walked in when he bumped into an old acquaintance, Professor Jiao Mingwu, a teacher of the former advanced algebra class.

"Professor Xu." The old professor greeted with a smile.

"Professor Jiao, are you going to class?"

"Yes, freshman advanced algebra."

The two exchanged a few pleasantries, and Professor Jiao held his teacup and went to the stepped classroom at the end of the first-floor corridor.

As soon as Professor Jiao arrived in the classroom, a student asked impatiently: "Professor, was that Professor Xu who just passed by?"

"Hmm."

Professor Jiao nodded with a smile.

"Wow, Professor Xu. Is it too late to go out and find him for an autograph now?" Someone tilted his head and looked out the window.

"He has already left. It's my first time seeing a living Professor Xu; he is much more handsome than on TV."

"Ah, you haven't seen him? Professor Xu opened a course on the Riemann Hypothesis and comes to school every week," someone said.

"No, I wanted to go to the class last week, but don't we have class?"

Under the stage, the students whispered.

The class bell rang.

"Alright, let's have class first. I left you a question last week. Raise your hand if you solved it."

Professor Jiao scanned the circle, seeing everyone looking at each other, he drank tea, put down the cup, "You guys, if you had one-tenth of Professor Xu's level, would I still need to worry so much?"

One-tenth...

The students under the stage were speechless. If this big shot's one-tenth, would they still need to sit here and attend class? They would have already taken off directly.

These old professors often have "Professor Xu used to..." on their lips.

This is simply incomparable, okay?

Professor Xu is a god, and they are just ordinary mortals.

"This question requires the use of partial knowledge of matrix inversion and rank calculation..." Professor Jiao knocked on the blackboard and didn't waste time, directly starting to explain the question.

In the past, he would also come up with some difficult questions to cool down the newly enrolled students, don't think that you are great just because you are in Kyoto University, you must know that there are people outside people, and there is heaven outside heaven.

Now there is no need to be so troublesome, just throw out the paper Xu Qingzhou wrote in his freshman year.

Look, this is the paper your Professor Xu wrote in his freshman year.

The effect is very good.

Office.

"Rare guest, come in quickly."

Gu Zhizhong had already gotten up to make tea when he saw Xu Qingzhou.

Xu Qingzhou was not polite to Gu Zhizhong either. After sitting down, he said: "I've been busy these days, just a little idle today. Isn't this, just happened to come over to drink a cup of tea."

In 6 years, the temples of old professors like Gu Zhizhong and Jiao Mingwu have added a lot of white hair.

Sitting in this office, Xu Qingzhou was occasionally a bit dazed. At that time, Professor Gu was helping him look at his paper here. That was already in 2014.

Not long after, the office was filled with the refreshing fragrance of tea.
