Chen Qiaoshan is already very familiar with the Tsinghua campus. He followed Wang Sifeng and Yao Yong and walked into the campus again.

The buildings in Tsinghua are a little old. There are many old houses with red brick or gray brick exterior walls on the campus, old buildings with a history of 70 or 80 years, and new houses from the 1970s and 1980s. However, as time settles, they have long lost their glory.

Of course, Tsinghua’s buildings are not only these two colors. The entire campus consists of four colors: black, white, red and gray.

Seeing Chen Qiaoshan looking around, Yao Yong asked, "What are you looking at?"

Chen Qiaoshan did not return directly, but said, "You Tsinghua University has a historical atmosphere, and the teaching buildings are older than the other."

Yao Yong smiled and said, "Is that a strong humanistic accumulation? You are not able to understand the wealth of landlords like you."

Chen Qiaoshan smiled, humanistic accumulation also requires money to support it.

The old building does look very historical, but its utilization rate is not high. It also requires a large amount of funds every year to maintain it, which is not as cost-effective as rebuilding it on site. However, history is history after all, and its inherent value is far from being replaced by steel and cement.

Chen Qiaoshan also had a deep understanding. When he went to Huanghe Tower before, when he saw the elevator inside the building, his interest was almost ruined, and he no longer had the feeling of Cui Hao as "there is no Yellow Hero Tower here."

A group of red buildings emerged in the distance, covering various buildings that were slightly low around. Chen Qiaoshan couldn't help but ask, "Where is that place?"

Yao Yong took a look and said, "There are Sixth Schools over there. They were just built last year. What is the Yuyuan Building? They were built by a Taiwanese capitalist donated money."

Chen Qiaoshan was not surprised. There were many people who liked to donate and build in Tsinghua University. Tsinghua Economic Management was named after Hong Kong banker Li Guowei and his wife Yi Helun.

Li Guowei was born into a famous family and was a famous philanthropist on Hong Kong Island. His ancestors were Li family, one of the four major families in Hong Kong and Britain.

The Li family started out by selling opium in the early years, and later entered the real estate industry and became a wealthy family. The grievances and hatreds of several generations can be regarded as a realistic version of the bloody drama.

Chen Qiaoshan doesn’t remember a Hong Kong and Taiwan tycoon named “Yu Yuan”. There is Cheng Yutong Building, but that was later Tsinghua Medical Building. It happened several years later. “Why haven’t you heard of this name in the Internet administrator?”

Yao Yong smiled and said, "Don't think it's bad. Yuyuan is a Taiwanese-funded enterprise."

Chen Qiaoshan felt something was wrong. He still remembered that later generations were named "Zhenweislovak" because of the Four Sects, which caused a big storm. They also paid for sponsorships. One was scolded to the point of being decent, while the other was ignored. This contrast is really strong.

...

When he arrived at the School of Economics and Management, Chen Qiaoshan asked, "Have you contacted someone? Where did you meet?"

Wang Sifeng said: "I haven't contacted him yet, but he has his mobile phone number, but it's turned off. Dr. Ye said that the person must be in school."

Chen Qiaoshan is a little terrible. With such a big campus, who knows where the people are? "What should I do now? Where can I find people?"

Yao Yong smiled and said, "I've asked someone to inquire. There is Professor Li's advanced microeconomics in the afternoon. Shen Jiye must be in class now."

"Just come to the door like this?" Chen Qiaoshan hesitated a little. Although he didn't do anything wrong, he lost all his face. It would inevitably make people feel embarrassed when he met Professor Li Daokui.

Wang Sifeng reminded: "Don't think so much, don't delay any more, find the person first before talking about it."

Chen Qiaoshan agreed with a tough time. He went to the computer room to see it, and everyone, including Dai Zhikang, was helpless.

Since the outbreak of the Sino-US hacker war, cyber attacks have come to the forefront overnight. Until now, the Chinese Hacker Alliance has attacked every day.

Reality is cruel, far less relaxed than in film and television dramas.

DDoS attacks will prevent the designated target from providing normal services and even disappear from the Internet. They are the most powerful and difficult to defend against cyber attacks at present.

So far, this is a world-class security problem that cannot be completely solved and can only be temporarily alleviated.

Chen Qiaoshan knew very well that when it came to professional issues, he could not get involved, so he could only find a professional to solve it. Even Wang Sifeng could not handle it, so he could only put his hope on Shen Jiye.

According to the address Yao Yong found out, several people found a small classroom and did not rush to go in.

Chen Qiaoshan looked inside and saw a thin teacher standing on the podium, with seven or eight students sitting sparsely below.

The person on the podium should be Professor Li Daokui. She looks younger than 40 years old and is absolutely young and promising. As for Shen Jiye, she really has no way to tell and can only see the students' backs.

"What, call the person out?" Yao Yong asked.

It was still class time, and Chen Qiaoshan didn't want to be too contemptuous, "Forget it, go in and wait." As he said that, he went into the classroom first, found a seat in the back row to sit down, and the two of them followed in.

The stage was talking about random dominance. Chen Qiaoshan came in halfway, feeling a little cloudy and mist, but after hearing it, the two of them next to him only persisted for a few minutes and then lost their energy.

When the course ended, the three of them did not attract the attention of others, nor did they contact Professor Li, and directly found Shen Jiye.

"Are you here to find me?" Shen Jiye looked at the person who came, obviously a little surprised.

Chen Qiaoshan didn't beat around the bush and directly pointed out his purpose, "Mr. Shen, we are from Qingshan Forum. The website was attacked by DDos in the afternoon. I want to ask you for advice."

Shen Jiye was stunned. He knew that Qingshan Forum was now famous, especially in the financial sector. Last time he bet with the Internet celebrities in Tianya, the bet of 100,000 yuan was not small, and countless netizens were waiting for the result.

The small and medium-sized board has been around for a few days. When Dazu Laser is listed, regardless of the winner or lose, the two forums will definitely become popular again.

Shen Jiye is a little frustrated. He can make a fortune by setting up a forum, but his own business has hit a lot one after another. Green League is still an unknown person. Could it be that he can only stay in Zhongguancun and rent a counter to sell computers in his life?

Everyone came to him, and Shen Jiye was not easy to refuse, so he asked about the specific situation.

Wang Sifeng said: "It's Syn, Flood attack, and our server can no longer respond."

When it comes to professional issues, Chen Qiaoshan couldn't get involved, so he simply left all the issues to Wang Sifeng and Yao Yong to handle.

After chatting for a while, Shen Jiye roughly understood the seriousness of the problem.

Green League's current products are specifically designed to deal with DDos attacks. He naturally understands the situation of Qingshan Forum. "Syn, Flood has been out for less than two years. It is considered a new technology and it is very troublesome to solve it. If the black hole is OK, the problem will be simple, but the machines are all outside now, so I can't do anything about it."

Wang Sifeng was very anxious. The forum was not going to go down all the time. If this continues, the loss would be too great. He even wanted to persuade Chen Qiaoshan to spend money to eliminate the disaster. "Mr. Shen, is there really no way?"

Shen Jiye can understand the feelings of several people. His understanding of DDos is much deeper than that of ordinary hackers. After thinking about it, "There are solutions, but it is difficult to deal with the symptoms but not the root cause."

Yao Yong said: "No matter whether it is useful or not, you can tell us first."

Shen Jiye did not hide his own privacy and said directly: "One is to shorten the timeout response time of Syn, which can reduce the server load exponentially, but it may affect normal users. Another is to identify IPs, but it cannot deal with IP spoofing."

Chen Qiaoshan said: "Mr. Shen, I would like to ask you to give us some technical guidance. If possible, I hope to cooperate deeply with Lusheng."

"In-depth cooperation?" Shen Jiye muttered. He didn't know how many days the Green Alliance could last.

In order to engage in research and development, he gave all his money, but unfortunately no one cared about the product. If he couldn't find a profit point, Green Alliance would be able to close down.

Not only Shen Jiye, but also Wang Sifeng and Yao Yong were surprised, and they couldn't figure out how to cooperate in depth with the Green Alliance.

Since he heard the word "black hole", Chen Qiaoshan has been unable to calm down. He doesn't know the Green Alliance, but black holes are too famous. The most notorious hacker tool CC attack in history was born to challenge black holes.
