"What? Someone wants to buy gel bait samples from you?"

In the office of the Dean of the School of Life Sciences.

Tian Liangwei looked at Chang Licheng with a serious expression.

One hour ago.

After noticing that something was off with Wang Zhaomin's actions, Chang Licheng immediately reported the situation to Xu Yun and was quickly brought to the Dean's office by Xu Yun.

Although Tian Liangwei was not the dean of their own department, the title of an academician still made Chang Licheng feel a bit uncomfortable. He shrunk his neck and said:

"That person hasn't contacted me for a long time, but today he suddenly talked to me about last night's incident.

At first, I didn't pay much attention to it, but when he said he wanted to buy gel bait with money, I felt something was strange.

Beijing is located in the north, and cockroaches are relatively rare here, let alone the American cockroaches that are mainly distributed in the south.

And in terms of closeness, there are at least five people in our major who are more familiar with him, such as Wang Siyuan from the neighboring class who is also from his hometown. It doesn't make sense for him to contact me....

So the more I thought about it, the more suspicious it became, so I went to Xu Shen...."

"You did the right thing."

After hearing the cause and effect, Tian Liangwei affirmed:

"This situation doesn't make sense logically. It is very likely that because the other party has been staying in Luzhou for the past few years, he has formed a stereotypical impression of cockroaches.

But recently, when he went to Beijing, he couldn't see many cockroaches around, so he used the usual template in his expression and revealed his true intentions.

After all, as you said, Wang Zhaomin was just an ordinary advertising student from another school before, so he might not be very careful with his words.

Of course, we cannot rule out the possibility that he did see some American cockroaches. Although they are rare in the north, they are not completely extinct...."

Thinking of this, Tian Liangwei turned to Xu Yun and asked:

"Xiao Xu, what do you think?"

After a moment of contemplation, Xu Yun glanced at the computer on the table and said:

"How about... we ask Director Wang Qingchen from the Network Information Center to take a look? Let's first determine the location of the other party."

Tian Liangwei smiled and pointed at him with his index finger, looking very happy:

We are "pawread dot com", find us on google.

"Xiao Xu, we are on the same page."

As one of the most prestigious universities in China, in addition to being frequently criticized by some ill-intentioned people in public opinion, there have been numerous battles in the field of network security, which often surpass public opinion.

Therefore, although the development of computer science at the University of Science and Technology of China was relatively slow, and it was not until later that it separated from the School of Information to become an independent School of Computer Science.

But in terms of network security capabilities, apart from Tsinghua University, Zhejiang University, Beijing University of Posts and Telecommunications, and Shuimu University, hardly anyone can surpass the University of Science and Technology of China.

As the head of network security at the University of Science and Technology of China, Wang Qingchen's resume and abilities are naturally extraordinary.

Like Zhang Rui before him, he graduated from the mysterious Zhan Shuo University's Gold Digging College.

He used to be the deputy director of the Institute of Information Engineering of the Chinese Academy of Sciences and one of the top experts in network security in China.

In addition, Wang Qingchen was also one of the seven legendary top players of the Red Alliance. He fought side by side with Lion and Bing'er many times and was a true main member of the battle in 2001.

Later, the Red Alliance disbanded for some reason, and Wang Qingchen was hired as the director of the Network Security Office by the University of Science and Technology of China at the end of 2013, starting to protect the growth of the next generation.

After receiving Xu Yun's notification, Wang Qingchen quickly arrived at the scene.

The head of network security at the University of Science and Technology of China appeared to be in his forties, around 175 cm tall, with a relatively thin figure and unusually lush hair.

After arriving in the office, Wang Qingchen greeted Xu Yun and Tian Liangwei familiarly:

"Academician Tian, Dr. Xu, long time no see."

Xu Yun and Tian Liangwei nodded in return, and then Xu Yun described the situation that Chang Licheng encountered in detail:

"Director Wang, with only the other party's QQ number, can we roughly locate their IP or information?"

Wang Qingchen thought for a moment and replied:

"Querying the IP is simple. As long as the other party is not a top-level hacker, even if they use CDN, it shouldn't be a problem. As for personal information...

Dr. Xu, this may require applying to the official department for online connection. After all, we can't do anything illegal.

Of course, if our university wants to investigate, the procedures are relatively less cumbersome."

Upon hearing this, Tian Liangwei and Xu Yun, who were both computer novices who couldn't even distinguish a graphics card, felt relieved.

Then Wang Qingchen opened his own laptop and let Chang Licheng log into the QQ account.

"Class 2 of Applied Physics... Communication group for the 21st freshmen of the University of Science and Technology of China... I really like you, Jiaran... Gathering place for street racing veterans... ** enthusiasts club..."

After publicly executing Chang Licheng's QQ groups, Wang Qingchen finally found the previous chat records and began to investigate.

Half an hour later.Wang Qingchen clapped his hands together and made a gesture like a exploding star in the sky:

"OK, it's done. The IP address on the other side is 202.106.xxxxxx... It's a broadband connection in a residential area near Dahongmen, south of the Fourth Ring Road in Yanjing."

Xu Yun touched his chin thoughtfully and said:

"So it's really in Yanjing... Director Wang, what should we do next? Do we need to contact other departments for assistance in the investigation?"

In Xu Yun's opinion, once they had locked down the opponent's IP address, as long as they could gather information about the opponent's recent activities or financial transactions through channels, they would be able to determine the situation to a large extent.

However, to his surprise, Wang Qingchen shook his head:

"No need."

Xu Yun blinked, not understanding:

"...Ah? Why?"

Wang Qingchen pointed to the screen with an expression that said, "You don't think I locked down an IP address in just half an hour, do you?":

"Well, I specifically looked into the relevant information about this location, and finally found out...

The internet profiles of the residents in the area highly overlap with those of a certain company, including but not limited to the nodes that disconnect and reconnect to the internet every day, and the Wi-Fi connections of the company's Penguin accounts during working hours, and so on.

At the same time, the company's factory area is also very close to this area, so it can be roughly inferred that it is a dormitory building for a company."

"What company is it?"

"Let me check... Hmm, it's a foreign company called Senxia Co., Ltd., also known as Senxia Pharmaceuticals in Chinese. They mainly produce pesticides and related derivatives."
