At the same time that Tang Yan's mother reprimanded her daughter, Guo Haitao, who was thousands of miles away from Huaqing University, had just entered the house at this time.

Now that the teachers and students of Huaqing University have been on vacation, the originally lively campus has become a lot deserted, except for these faculty and staff living in apartments, there are basically no people on the huge campus.

But even so, Guo Haitao, who has always been engaged in the research of sensitive core cryptography, is still busy in the computer room of the laboratory all day long.

"It's back. Seeing her husband enter the door, his wife Zhao Ru greeted her with a smile, took the briefcase from Guo Haitao's hand, and gently put it in the closet next to her.

"It's quite fragrant, and the roasted eggplant you made for me again?" Guo Haitao asked with a smile.

"Aren't you going to be able to eat this bite in the past two days, and it's cheap to catch up with the super-similar eggplant, so you can eat enough." Zhao Ru said.

"Huh. Guo Haitao smiled when he heard this, and then said: "Rest in the afternoon, and finally finish the patch thing." ”

"It's been more than a month, and those people in the Security Service should have given you a holiday a long time ago. Zhao Ru shook his head and said.

"There's no way, this time the stakes are very high, once those loopholes are grasped by the intelligence agencies of other countries, the consequences will be unimaginable, what is it if I take a few days off." Guo Haitao said indifferently.

"How did those vulnerabilities suddenly come to pass? I remember that the encryption programs you designed before never had a vulnerability. Zhao Ru asked curiously.

"This time, thanks to Duan Yun's kid......," Guo Haitao said.

"Duan Yun, he can actually find a loophole in your design program?" Zhao Ru showed a look of extreme surprise on his face.

In terms of understanding Guo Haitao, no one can compare to Zhao Ru, the wife who has been born for decades, whether it is for him as a person or for his academic level.

In Zhao Ru's opinion, if her husband claims to be the second in Huaxia in the study of cryptography, I am afraid that no one will dare to claim to be the first!

Moreover, for more than 20 years, Guo Haitao has been the chief person in charge of the national sensitive cipher, responsible for the development of five generations of military ciphers, which shows the country's recognition and trust in his academic level!

So after hearing that Duan Yun had now found out the loophole in the encryption program designed by her husband, the degree of surprise was naturally conceivable!

"The back waves of the Yangtze River push the front waves...... Young people nowadays are amazing. Guo Haitao shook his head lightly when he heard this, and said: "To receive such a seedling as an apprentice, God treats me well!"

"It's a pity that this Duan Yun's education is a bit low. Zhao Ru said with some regret.

"I will find a way to help him, even if I help him write his papers, I will let him enter this academic circle!" Guo Haitao pondered for a while, and then said: "There are people with high diplomas, but a genius like Duan Yun is rare for decades!"

Guo Haitao walked into his study as he spoke.

For more than a month, Guo Haitao has been working late in the computer room almost every day, and he rarely even goes home for dinner, so he has never turned on his computer.

Now that he is free, Guo Haitao can finally turn on his computer, watch some news programs and academic websites at home and abroad, and pass the time a little.

It's just that after Guo Haitao turned on the computer, he saw that there were more than 100 emails in his e-mail, so he clicked on it casually.

Most of these emails were electronic journals of some foreign mathematics journals that he subscribed to, and after Guo Haitao glanced at them, he put them aside.

Guo Haitao soon discovered the email from Duan Yun.

After being stunned for a moment, Guo Haitao quickly clicked on the email.

It has been more than a month since the last meeting between master and apprentice, during which Guo Haitao sorted out a sample essay for his doctoral dissertation and more than a dozen selected topics and sent them to Duan Yun, hoping that he could find a research direction and write a paper that could be published in domestic and foreign journals.

After all, if you want to achieve the level of publication in mathematics journals at home and abroad, you must have a high quality, even if Guo Haitao asks Huaqing University to recommend it, it is impossible to reduce the standard of accepting manuscripts too much, otherwise, it will affect the authority and credibility of the journal.

According to Guo Haitao's idea, Duan Yun only needs to produce a less difficult paper in the next year, and after ten years, after accumulating a certain number of manuscripts, Duan Yun should be able to obtain the honorary title of the school, so as to successfully enter the academic circle with this title, and finally take over Guo Haitao's 'mantle' little by little and become his successor.

This is what Guo Haitao wants to achieve in the end!

It's just that only a month has passed, and Duan Yun has sent him an email, which has somewhat aroused Guo Haitao's curiosity.

Guo Haitao's first reaction was that Duan Yun was likely to have encountered problems in the research thesis project, after all, even the least difficult dissertation direction listed by Guo Haitao for Duan Yun was extremely difficult for ordinary doctoral students, not to mention that Duan Yun's main business was to play football, and mathematical research was just his hobby, and it was reasonable to encounter difficulties.

But the moment he clicked on the email, Guo Haitao was attracted by the title of the Chinese file attachment of Duan Yun's email.

I saw that the title of the attachment reads "Arguments and Reasoning on the Hodge Conjecture".

Guo Haitao thought that his eyes were spent, and after taking off his glasses, he wiped them carefully and put them on the bridge of his nose again.

After confirming the title again, Guo Haitao clicked on the attachment.

In an instant, a paper full of data and analytical theories appeared on the computer desktop.

Until now, Guo Haitao still can't believe that Duan Yun has solved this problem, which is known as one of the top ten problems in the mathematics world and has plagued countless mathematicians for a century!

In addition, Guo Haitao also studied this Hodge conjecture for a period of time in his early years, and the feeling to Guo Haitao at that time was that this Hodge conjecture involved too many advanced mathematical theories, and the arguments and data required were too complex, and even made people feel that they couldn't start at all!

In the end, Guo Haitao's research on Hodge's conjecture only lasted for more than a month, and after still not finding a clue to the argument, he finally chose to give up reluctantly.

The reason why Guo Haitao would send the proposition of Hodge's conjecture to Duan Yun before was that he didn't report any hope at all, but just wanted Duan Yun to try it and get in touch with some of the industry's top mathematical problems.

But Guo Haitao never expected that Duan Yun would really choose the most difficult one among the more than ten propositions, and it only took a month to write the paper.

With full of doubts, Guo Haitao carefully checked the paper.

When Guo Haitao saw that Duan Yun used the theory of topology as an introduction at the beginning, he couldn't help but shake his head, because in his opinion, this should obviously not be the right answer.

But after looking at it for a while, Guo Haitao's eyes suddenly became stagnant......
