The days are changing day by day, the world is changing day by day, because of the appearance of Kuang Tong, Zhang Bin has more time to soak in the library, and Kuang Tong is also actively following Han Sen to establish a new network of contacts, Yao Ruzhi, Zhuang Wen and Qin Lan are sorting out Han Sen's papers while perfecting their own new ideas.

At the end of the two sessions, Han Sen was finally busy.

After a long absence, everything is very comfortable, and Han Sen's beautiful Bentley Continental coupe has reappeared on the campus of Tsinghua University.

The Continental car stopped in front of the small red building at Wudaokou.

"Hello Han Xuewei!"

"Hello!"

"Han Xuewei!"

"Hello Professor Wang!"

......

Walking into the small building, the faculty, staff, and students who came and went back and forth in the corridor greeted Han Sen respectfully.

“hi！” Walking into his office, Han Sen greeted several students.

"Hello boss!" After getting acquainted with it, several students no longer called Han Sen "Han Xuewei" and "Han Academician", and uniformly called Han Sen "boss".

Han Sen nodded, they were all about the same age, even Zhang Bin and Kuang Tong were older than Han Sen, Han Sen really couldn't put up a stand in front of them, he liked the title of "boss" with Park Kan very much.

Han Sen walked to Zhuang Wen's table, handed Zhuang Wen a bag, and said: "Zhuang Wen, this is a custom book, custom fountain pen and top schoolbag for the two sessions, anyway, I will give you a copy of all the souvenirs that can be taken at the venue, take it home to your brother!" ”

For a high school student, the souvenirs of the two sessions are still very face-to-face, this is Zhuang Wen specially asked Han Sen to help him bring it, his younger brother Zhuang Wu is going to be in the third year of high school this year, Zhuang Wen wants to give his younger brother Zhuang Wu a gift.

Satisfied, taking the small souvenir handed by Han Sen, Zhuang Wen smiled and said, "Boss, why don't you help write a word of reward?" ”

Han Sen thought for a while, wrote a sentence under the title page of the notebook: "Heaven rewards hard work", and then signed his name.

The neat writing has no artistic value, but it is solemn and rigorous.

A word, a small gift, has an immeasurable impact on the growth of teenagers.

Because of this encouragement, Zhuang Wen's younger brother Zhuang Wu began to work hard throughout his third year of high school, and he was admitted to the Department of Mathematics of Tsinghua University with the top score in the province, and a few years later, he became Han Sen's doctoral student, of course, this is the distant future.

Han Sen picked up the cup, took a sip of water, and asked, "Recently, has there been any major events in the school?" ”

"Yes, yes!" Yao Ruzhi said excitedly: "Boss, do you know which god is next to our office?" ”

"Who?" Han Sen walked to his desk, put down the water glass, and asked curiously!

The excited Zhuang Wen rushed in front of Yao Ruzhi and spoke: "Oh my God! O Pierre Deligne, O Pierre Deligne! He, he's been to our office many times! You see, he's signed it all for me! ”

"it!" Han Sen was excited when he heard this name, Pierre Deligne was Han Sen's idol, Han Sen immediately said excitedly: "My God! O my idol! I, me, me, everything you have his signature, my God, you bunch of things, you didn't sign a copy of it! ”

Hearing that it was next door to the office, Han Sen immediately rushed over: "He, where is he?" ”

Qin Lan spoke: "Big brother, this is PBC School of Finance, and Professor Deligne is a professor of mathematics!" ”

Han Sen also sensed his stupid behavior, kicked Qin Lan, who was talking coldly, and asked, "Fuck off, he, where is he?" ”

"He has a lecture at two o'clock this afternoon, it is his first lecture at our Tsinghua University, and now it is half past one, he should be in the auditorium!" Yao Ruzhi spoke with a little temper, if Han Sen hadn't sent a message at noon today saying that he was going back to school, now a few of them would not be stuffed in Han Sen's office, but crowded in the auditorium to be ready to accept the "baptism" of the big guy Pierre Deligne.

Han Sen immediately got up: "You didn't even tell me in advance about such important news, let's go, hurry up!" If there is no place for it, see that I don't kill you! ”

......

When Han Sen arrived at the auditorium, the entire auditorium had been surrounded by three floors inside and three floors outside, not only from Tsinghua University, but also scholars and students from universities in Beijing.

Pierre de Ligne, the great man, completed his doctoral dissertation in 1968 under the direction of the "Pope of Mathematics" Grothendieck. In 1970, at the age of 26, Deligne became a professor at the Institut des Hautes Etudes des Sciences in France. There he completed his work on Hodge Theory and the Wey Conjecture. Deligne moved to the United States in 1984 to join the Institute for Advanced Study in Princeton, where Hansen had the privilege of meeting him several times.

Now he actually appeared at Tsinghua University!

His appearance is like a powerful magnet to attract the "worship" of the Chinese mathematical community.

Therefore, the entire Tsinghua University is full again.

Tsinghua University opened the stadium as a parking lot, and each foreign school bus asked for a fee of 100 yuan, and a group of security guards were very familiar with the high parking fees of top scholars and professors.

Students from other majors at Tsinghua University are more sophisticated, they are not interested in Professor Deligne, but they are interested in making money, and they don't know where to get bottled water and ice cream, and sell water and ice cream near the auditorium.

This is the international influence of a scholar, and Professor Deligne has led the GDP of the entire Tsinghua University to a small peak.

......

When Han Sen arrived at the auditorium, it was already full of people on the inner and outer three floors.

With so many people, what should I do, in fact, it was easy for Han Sen to find the conference staff and enter the auditorium as him, but Han Sen really didn't expect that he would be like a brainless little fan brother now.

I took a look in my pocket, and there happened to be a "work permit" for the two sessions a few days ago in my pocket, so Han Sen put on his work card and began to squeeze into the crowd, pretending to squeeze while saying: "Let it, let it go!" Borrowed, borrowed, hey! Classmates, let me go, I'm a staff member! Give it a go! ”

The shrewd Han Sen squeezed into the auditorium very smoothly, but Yao Ruzhi, Zhuang Wen and Qin Lan, who stayed outside, stayed outside with a confused expression, what is the situation, the three of them originally wanted to find a VIP seat in the name of Han Sen, you know, Professor Deligne appeared at Tsinghua University for Han Sen, as long as Han Sen was informed that he was going to come to listen to the lecture, Han Sen would get the treatment of absolute VIP, and the three of them would also follow Han Sen to take advantage, would they need to squeeze in like this?

The three of them looked at each other, and really wanted to point at Han Sen who was squeezing towards the auditorium and shouted, "He's not a staff member!" ”

As long as you're thick-skinned enough, the world is all yours.

Han Sen squeezed into the auditorium very smoothly, the entire auditorium was already overcrowded, the corridor was full of people, there were no seats for a long time, Han Sen squeezed and sat on the ground, as for Yao Ruzhi, Zhuang Wen and Qin Lan, where do you like to go.

Excitedly, Han Sen took out a small notebook, looking forward to his idol with little stars on his face.

Beside Han Sen, several young teenagers secretly looked at Han Sen and discussed in a low voice:

"This, isn't this Academician Han Sen!"

"No, it's impossible, Academician Han Sen is sitting on the ground?"

"I don't know, it seems!"

"Why don't you ask?"

"Why don't you ask?"

.....

"Be quiet!" Han Sen, who was determined to be a student, respectfully waited for the teacher's appearance, and was annoyed by a few teenagers around him, and Han Sen reprimanded him unhappily.

A group of teenagers next to him were immediately startled, this TMD is really Academician Han Sen, big guy, why can you be my side!

Several teenagers were immediately frightened by Han Sen, obediently without saying a word, sitting upright,, I, we were reprimanded by Academician Han Sen? You must know that in the hearts of this group of undergraduates, Han Sen's status is higher than that of Pierre Deligne.

Although they were reprimanded by Han Sen, they had a lot of fear, but they were more excited, and it was Academician Han Sen who was crowding around them!
