Today's Guo Haitao is over sixty years old, and for people of his age, fame and fortune have long been a thing of the past, not to mention that he has almost all the honors he can get as a scientist, so today's Guo Haitao is really indifferent to fame and fortune.

If there is anything that Guo Haitao can't reassure or still regrets, it is that he is very worried about his academic 'no successor'.

This may sound strange to outsiders.

As the top university in China, Huaqing has always been the smartest and best among the tens of millions of students in the country, and it is far from being comparable to ordinary universities in terms of intelligence and diligence.

And unlike Beijing University, which has the same name as Huaqing, the students who enter this school are not keen on politics, and the proportion of doctoral and master's students in related disciplines is very high, and it has been sending the top young talents in various disciplines to the country for decades.

In fact, Guo Haitao is a professor and doctoral supervisor of the Department of Mathematics in Huaqing, and all his students are the elite of the elite, smart and diligent enough.

Although smart and hard-working people are indeed easy to succeed, as the saying goes, success is 99% diligence plus 1% talent, but if you want to really stand at the top of a discipline, that 1% talent is far more than 99% effort!

Guo Haitao has made remarkable achievements in research for decades, and in his opinion, maybe the students under him are indeed excellent, but Guo Haitao needs not talents, but geniuses!

Duan Yun is the first student who makes Guo Haitao feel bright, he can even take a top event like the National Mathematics Olympiad as a challenging game, and it can be easily completed Guo Haitao didn't think of the answer, from this point of view, Duan Yun is definitely a good 'seedling' that is rare in ten years!

"I heard Yang Ying say, you are now a football star?" After entering the campus of Huaqing University, Guo Haitao asked Duan Yun with a smile.

"Hmm. Duan Yun nodded, and then said, "I'm just eating with a mouthful of food." ”

"Hehe......" Guo Haitao smiled when he heard this.

In fact, Guo Haitao never watches football, and he disdains those stars and the like, in his opinion, sports will only make people strong, but science and technology are the foundation of a nation's strength!

He invited Duan Yun to Huaqing today, mainly to test how much potential Duan Yun has in mathematics, if Duan Yun is indeed talented, he can arrange a more 'promising' job for him.

"This Huaqing University is really too big...... although Duan Yun is not the first time to come to Huaqing, he is still shocked by the environment of this century-old famous school, although many buildings look a little old, but they are full of thick heritage and history, and even make Duan Yun feel a little sacred.

"If you have the opportunity, do you like to study and work here?" Seeing Duan Yun beside him looking around from time to time, Guo Haitao asked with a smile.

"I think it's more suitable for retirement, it's quite quiet. Duan Yun replied casually.

"Haha. Guo Haitao smiled when he heard this, and then stopped talking.

Crossing a tree-lined path and a man-made lake, Guo Haitao led Duan Yun to an apartment building that looked a little old.

The housing of lecturers and professors at Huaqing University is basically allocated by the government, and even in the center of the capital city, where every inch of land is valuable, the state still does not hesitate to plan a large area of land to give these top scientific and technological elites a comfortable place to live.

And when Duan Yun walked forward for a while, he was surprised to find that there were actually armed policemen standing guard at the gate of this faculty residential area, and they were four armed policemen with loaded guns!

Duan Yun was taken aback by seeing this formation, it can be seen that the state still attaches great importance to the security of these scientific researchers, which is a treatment that money cannot buy!

However, these armed policemen are obviously quite familiar with Guo Haitao, Guo Haitao just said a few words, and those armed policemen let Duan Yun enter the community.

Guo Haitao's residence was located in the innermost three-story building in the innermost part of the community, and after Duan Yun followed him into Guo Haitao's room, he was immediately stunned by the scene in front of him.

Guo Haitao's house looks nearly 100 square meters, and the house is quite clean, but the furniture in the room is relatively old and simple, but the number of books stacked in it is staggering.

I saw that in the huge living room, in addition to a sofa and a TV, the walls were surrounded by bookcases, which were full of all kinds of books, and even because the bookcases could not be placed, many books were simply placed in the corridor and bathroom, at a glance, it was like a small library.

Moreover, Duan Yun also found that many of these books were in foreign languages, including English, Japanese, and even many words that even Duan Yun couldn't name, and the book cover and paper were slightly damaged, apparently after a long time of reading!

"Mr. Guo, you have read so many books. Duan Yun exclaimed.

"A lot of them were read when I was younger, but in fact, the really useful content in a book is only a few pages. Guo Haitao smiled when he heard this, and then said to Duan Yun: "You sit down first, and I'll pour water for you." ”

"Forehead......" Duan Yun was about to say a few polite words, and then he found something that surprised him even more.

In a row of bookcases in the living room, there are more than a dozen photo frames, some of which are obviously photos of Guo Haitao and his family when he was young, and others are group photos of some previous high-level national leaders!

This can't help but Duan Yun is a little smacked, but it is also common sense, after all, Guo Haitao is the top mathematician in China, and it is not surprising that he is even called a 'national treasure'!

"Drink tea. At this time, Guo Haitao came over with a plate of tea sets and said to Duan Yun with a smile.

"I'll come by myself!" Seeing this, Duan Yun hurriedly took the tea set from Guo Haitao's hand.

Although Guo Haitao's life looks quite simple, Duan Yun found that his tea set is quite exquisite, antique, serious purple clay pot, and the aroma of tea is fragrant, which makes people feel refreshed and happy.

"Good tea. After Duan Yun took a sip from his teacup, he couldn't help but praise.

"Hehe, there aren't many young people who like to drink tea now, and I'm worried that you don't like it. Guo Haitao said with a smile.

"Teacher Guo, you didn't just call me here today to invite me to tea, right?" Duan Yun asked after putting down the teacup.

"Well, I called you over today, in fact, I want to ask you a math problem, I wonder if Duan is willing to help me solve it?" Guo Haitao said in a rather polite tone.

"I said Mr. Guo, don't use the word "ask for advice", I really can't afford it, even you can't answer the question, how can I solve it with a half-ass?" Duan Yun said with a respectful face.

Although Duan Yun is indeed a master of mathematics, he does not dare to have the slightest support in the face of a highly respected figure like Guo Haitao, which is also a kind of respect for Guo Haitao.

"Duan Yun is too modest. Guo Haitao smiled when he heard this, then got up and took out a test question that had already been prepared from the bookcase next to him, put it in front of Duan Yun and said, "You can help me take a look first......
