This dinner was quite warm and pleasant, during the dinner, Guo Haitao and Duan Yun exchanged mathematical things with each other, and as the exchange deepened, Guo Haitao looked at Duan Yun with more and more love in his eyes.

After the meal, Zhao Ru cleaned up the dishes and chopsticks, and Guo Haitao made a new pot of tea, and sat with Duan Yun and sipped comfortably.

"Xiao Duan, how do you feel about being a player now?" asked Guo Haitao.

"It's okay, it's just a mouthful of food. Duan Yun put down the teacup in his hand and said with a smile.

"Do you like math?" Guo Haitao asked again.

"Of course I do. Duan Yun replied very simply.

In fact, Duan Yun's so-called liking is that he likes to treat mathematics as a kind of entertainment, just like playing chess and other brain-moving games, it is completely for the purpose of recreation.

But when this sentence heard Guo Haitao's ears, his eyes lit up.

"Then what do you think of Huaqing University? ”

Huaqing is one of the top schools in the country, and it is naturally a place that everyone yearns for. Duan Yun pouted and said.

"Haha, that's right, Huaqing University is indeed a famous school that everyone yearns for, but there are very few people who can enter this school to study and work. Guo Haitao paused, and then said: "But you are definitely qualified to work in Huaqing." ”

"How is this possible?" Duan Yun was stunned for a moment when he heard this, and said, "I have been expelled from the school in Heyang because of that incident before, and my qualification for escort has also been cancelled, how can I still enter this school?"

"As long as you want, I can apply to the school to let you be my external opponent, and this is no problem at all. Guo Haitao said confidently.

Professor Guo ...... "At this moment, Duan Yun understood Guo Haitao's intentions, and only heard him say: "I have always respected people like you, because I have never been able to reach this state of yours in my life, whether it is to be a scholar or a person, I am just an ordinary person, I want to live a leisurely life, I don't want to be too tired......"

Duan Yun's words are very clear, that is, he has no interest in coming to Huaqing to engage in scientific research.

"Everyone has their own aspirations. Guo Haitao's face showed disappointment when he heard this, and he only heard him say: "You have a high mathematical talent, if you can embark on this road, the future is limitless, and there is money to be made in scientific research......

"Mr. Guo, whether you believe it or not, in fact, I used to study mathematics only for scholarships and university admissions, but now I have a better life plan, and I am very satisfied with my current life. Duan Yun interrupted Guo Haitao's words and said.

"Uh......" Guo Haitao sighed lightly when he heard this.

He obviously regretted Duan Yun's choice, after all, Duan Yun could be regarded as the best graduate of mathematics with the highest talent and the greatest potential that he had seen in the past few decades.

"But if I had time in the future, I'd like to come and sit with you and work on some interesting math problems together. Duan Yun smiled at Guo Haitao, and then said: "Maybe you don't believe it, I like to do problems, just play chess, it's also a kind of entertainment." ”

"Do you like to do questions?" Guo Haitao's eyes lit up when he heard this, and he seemed to think of something.

"Hmm. Duan Yun nodded and said, "The questions you gave me just now are quite good, especially the last one...... That, my level is a little worse, I haven't finished the calculation, can you let me take this question back, and I will study it slowly?"

"Yes! Of course no problem!" Guo Haitao replied very simply after hearing this, only to hear him groan for a while and then said: "Actually, I still have a lot of interesting math problems here, as long as you want, you can take it back and do it." ”

"Hehe, thank you so much. Duan Yun said with a smile.

"Wait. At this time, Guo Haitao stood up and walked to the study.

After a full five or six minutes, Guo Haitao walked out of the study again, holding a stack of printed paper in his hand and handing it to Duan Yun.

"This is a variety of interesting math problems that I have compiled and collected over the years, if you are interested, take the time to do it, and next time you have time, you can always come to me, as long as you like to do the problems, I will always provide them to you. Guo Haitao said to Duan Yun with a smile.

"Okay, good!" Duan Yun's face was overjoyed when he heard this, and he immediately took the pile of paper handed over by Guo Haitao.

"Take a bag and put it in it. Guo Haitao took out a file bag from the bookcase and handed it to Duan Yun.

"Hmm. ”

Duan Yun knew that the questions Guo Haitao found for him should be quite difficult, and they could not be compared with the various Olympiad papers sold on the market.

For Duan Yun, the reason why he is willing to do these problems is because of entertainment on the one hand, and on the other hand, he doesn't want his master-level mathematical talent to be wasted, maybe he will be useful in this subject in the future.

It's just that what Duan Yun didn't know was that Guo Haitao put some very special 'groceries' in the test paper he gave him.

What Duan Yun would not have thought was that this application would change the trajectory of his life in the future......

But at this time, Duan Yun still didn't know about it, and in the rest of the time, Duan Yun talked to Guo Haitao about other things.

"Mr. Guo, I actually envy you. Duan Yun watched his wife Zhao Ru bring the washed fruit to the two of them, turned around and walked into the kitchen, and said to Guo Haitao with a smile.

"Hehe, what do you envy me?" Guo Haitao asked with a smile after hearing this.

"I would like to ask you a personal question, I wonder if Mr. Guo is willing?" Duan Yun Zhengse said.

"Say!"

"That's right, when we were eating just now, I saw that you and your wife were really very affectionate, I want to know, how did the two of you manage to keep this relationship warm for so many years?" Duan Yun said with a deep groan.

There is no doubt that in Duan Yun's view, Guo Haitao and Zhao Ru can still have a sense of respect for each other for so many years, which is very rare in today's society.

Because for most families, after decades of marriage, the passion has long faded, the love has disappeared, and all that remains is marriage.

But from the time they were eating just now, Guo Haitao and his wife's unpretentious show of affection made Duan Yun a little incredible.

"Huh. Guo Haitao smiled when he heard this, and said, "You can be regarded as asking me." ”

"Well, if you can't say it, forget it. Seeing this, Duan Yun smiled and said.

"Actually, there's no secret, maybe it's just that we feel like we both have endless wisdom. At this time, Guo Haitao paused, then got up and took out a few thick notebooks from the bookcase, and said to Duan Yun, "I can show you this." ”
