Guo Haitao's meaning is very clear, that is, he wants to accept Duan Yun as an apprentice.

Strictly speaking, there is only a teacher-student relationship in academics, but Guo Haitao's master-apprentice relationship is obviously a closer relationship than his relationship with those graduate and doctoral assistants under him.

Guo Haitao is really a talent.

In his opinion, it is very, very difficult to find a 'successor' who can take charge of the real level of talent, even more than the topic he is currently studying, after all, as long as the difficult topic is persistent, there will be a day when he can solve it, and finding a real genius in cryptography can only rely on chance and luck.

"Teacher Guo......" Duan Yun saw Guo Haitao's thoughts, and after seeing him ponder for a while, he said: "I'll tell you the truth, I respect you, Teacher Guo, and I also like mathematics, but mathematics is really just my hobby, and I am very satisfied with my current life, and I have no intention of changing careers for the time being......"

"Hmm......" Guo Haitao nodded lightly when he heard this, and a touch of loss flashed on his face.

In fact, he had long known that Duan Yun would most likely reject him, but today he couldn't help but ask Duan Yun again.

"But there are no absolutes, and no one can predict what will happen in the future. Duan Yun paused, and then said: "Teacher Guo, whether it is knowledge, conduct or life realm, is beyond my reach, it is my Duan Yun's honor to be able to worship Teacher Guo as a teacher, but I don't want to engage in mathematics for the time being, if Teacher Guo you accept my condition, I will call you a master today!"

Duan Yun's words were very sincere, and although Duan Yun himself was also a master of mathematics, in terms of being a man, Guo Haitao was also enough to win Duan Yun's respect, so accepting Guo Haitao as a master, Duan Yun was completely acceptable.

Moreover, after Duan Yun was reborn, among the people he came into contact with, there were only two people who could be called top academic figures, one was Chen Haisheng, a master of traditional Chinese medicine, and the other was Guo Haitao.

Although Duan Yun is rich, his social status is not high, compared to academicians and scholars like Guo Haitao, who have already achieved fame, he is only a small nouveau riche at best, and if he wants to make a difference in Kyoto in the future, he must have strong connections.

Establishing a friendship with such a top person will naturally help Duan Yun in the future.

So after comprehensive consideration, Duan Yun decided to establish a master-apprentice relationship with Chen Haitao.

It's just that Duan Yun wouldn't have thought that apprenticing with Guo Haitao would make a major turning point in his future life!

"I can understand your thoughts, in fact, when I was young, my heart was also very big, I wanted to do business, I wanted to be a soldier, I wanted to go to the army, I wanted to go to the war, but in the end I found that people only need to do one thing well in this life......" Chen Haitao pondered for a while, and then said: "In fact, the simpler people live, the more comfortable they will be, I just said, I will not force others to do anything, I will not object to what you want to do, and I think you will one day be the same as me......"

"I see. Duan Yun nodded, and then picked up the wine and poured it to the cup of himself and Guo Haitao, then suddenly got up and picked up the wine glass and walked in front of Guo Haitao, and then slowly knelt in front of Guo Haitao, and said, "Master is above, apprentice, I toast you!"

The man has gold under his knees, kneels to the sky and kneels to his parents, and he will be a father for life if he is a teacher for a day, so Duan Yun's move is to admit Guo Haitao as a master!

"Huh. Seeing this scene, Guo Haitao smiled and said to Duan Yun: "Hurry up, don't do this now, you just need to give me a verbal promise." ”

Although Guo Haitao motioned for Duan Yun not to kneel, he still took the glass of wine from his hand.

The next moment, Guo Haitao raised his head and drank all the wine in the cup.

"Congratulations to Mr. Guo. Seeing this, Yang Ying on the side said with a smile.

This is exactly what Yang Ying wants to see.

Although Guo Haitao is a professor of Huaqing, he is the person in charge of the national cryptography project, and his identity is quite sensitive, and he is not suitable for long-term contact with ordinary people like Duan Yun.

And now that the two of them become masters and apprentices, there will be more and more mutual learning and exchanges, which means that Duan Yun can often enter and leave Huaqing in the future, which will also provide her with a lot of opportunities to meet Duan Yun!

"Master, if you need my help with anything in the future, it is incum......bent on you to be an apprentice," Duan Yun paused, and added: "Of course, I really don't want to join your research group now, and I don't plan to take the research mathematics exam yet......"

"Hahaha, that's okay, I said, I won't force you to do anything. After drinking the apprenticeship wine that Duan Yunjing gave him, Guo Haitao's face suddenly relaxed a lot, and he only heard him say with a smile: "I still have time, I can wait slowly......"

"Teacher Guo, eat. Yang Ying on the side was also very attentive to Guo Haitao at this time.

Next, the atmosphere in the restaurant became much more relaxed, and Duan Yun told some interesting stories about him in the team and the national team, including the fact that the BT physical trainer tortured the lazy national football team in various ways. 、

Duan Yun's eloquence was very good, and he often provoked Guo Haitao and Yang Ying to laugh constantly, and the dinner party was quite pleasant.

And Guo Haitao also talked about some of his experiences after joining the Huaqing scientific research group in his early years, including the reception of three generations of national leaders, which attracted Duan Yun and Yang Ying's admiration.

Maybe Guo Haitao did not get amazing money and wealth in his life, but there is no doubt that he has won a lot of honors, fame and fortune that ordinary people can only look up to, and he chose the former.

It's all a matter of personal values.

At this point, the current Duan Yun is obviously more interested in wealth.

Duan Yun's dinner lasted until ten o'clock in the evening.

After Yang Ying put away the dishes and chopsticks, she washed them in the kitchen alone.

After making a pot of tea, Duan Yun respectfully handed it to Guo Haitao.

"Sit down, there's something I want to give you. Guo Haitao motioned for Duan Yun to sit down, then took out a plastic box from the satchel he was carrying with him and handed it to Duan Yun.

"This is ......" After Duan Yun opened the box, he found that there were three discs inside.

"Here are some of my research experiences in cryptography over the years, and there are a lot of data and cryptography cases that I think will be of interest to you. Guo Haitao stretched out his finger and pointed to the red disc at the top of the box, and said to Duan Yun: "In addition, this red disc is a new type of encryption method that I have researched in the past two years, if possible, I hope you can find some loopholes in it, this is very important to me......
