Hearing Xu Yan's question, Huang Shan was silent for a moment, and he showed a bitter smile: "Brother, what you are asking is, I am indeed a little discouraged - uh, to put it more bluntly, I am a little scared." ”

Opening the window and looking at the campus where the lights were shining outside the window, Huang Shan said in a deep voice: "We are criminal policemen, whether a case can be solved or not, when we come into contact with the case, we can probably weigh a few points -- I had a feeling at the beginning, this batch of cases in Shudu is not something we can handle." ”

Xu Yan raised his eyebrows slightly, he let out a "hmm" and motioned for Huang Shan to continue.

"We're detectives, we're armed with guns, we're specially trained, but we're still ordinary people with mortal bodies, but—"

Huang Shan turned to face Xu Yan, drew his hand out of the window, pointed to the darkness of the campus outside the window, and said resolutely: "He, he is definitely not an ordinary person!"

"Brother, I'm not a timid person, I've been a police officer for almost 20 years, I've seen a lot of dead scenes, I've seen many disgusting scenes of broken corpses and beheadings, and now I'm numb.

But in the case of Shudu University, seeing the head that was pulled out alive, I had nightmares for several nights in a row - these cases are very strange, and there is a very heavy evil aura in them, this is a very evil force, and it is not something that ordinary people like us can deal with-"

Xu Yan smiled: "It seems that tonight, after seeing our investigation team, Brother Huang feels more disappointed?"

Huang Shan smiled, he did not deny: "...... I can see that Major Zhang should have kung fu. It should be very good. There are several others, look at their frames and movements. It should also be very capable of fighting. But well...... No matter how strong they are, they are just ordinary people. But we're going to deal with it. but supernatural evil...... It's a real demon monster. From this point of view, I would rather send me some monks or Taoist priests who can exorcise demons and demons. ”

Saying that, probably Huang Shan also felt that his words were too ridiculous, and smiled at Xu Yan.

At this time, Huang Shan seemed to remember something: "By the way, brother, there is a good thing, I don't know if you are interested." ”

"Ah, what's that good thing?"

Yellow Mountain is close to Xu Yan. Lowered his voice: "Brother, let me ask you--you are an intelligence department, your chief should pay more attention to espionage cases, right? If you can catch a lurking foreign spy, it should be good for you, right? Can you get a second-class merit or a third-class merit?"

Xu Yan was stunned for a moment and replied, "I don't know much about catching spies." The ministry should attach great importance to this matter, but it is difficult to say what kind of merit it can be made, and it should have something to do with the weight of this spy -- if it involves major intelligence. There should be meritorious service awards. ”

"Oh, it's good to have meritorious service. Fertilizer and water do not flow into the fields of outsiders, and it is better to give this clue to you, brother, than to cheapen the national security in the city. ”

"Brother Huang. What are you talking about?"

Although he knew that there was no one around, Huang Shan still glanced around: "Brother, I remember." You also attended the last task force debriefing meeting, right?"

"Yes. Participated. ”

"That's good! There's something you heard at that meeting. I don't need to explain it to you - in short, in order to crack the case and avoid causing social panic, our network supervision and technical investigation joint communication operators in the city monitor the communication and Internet activities in Shudu University and the surrounding areas, including email, QQ, WeChat and other data transmissions are within the scope of our monitoring...... As long as someone talks about "murder", "homicide" or the name of the victim, the time and date of the crime, and other information related to the case on the phone chat or online communication tools, our monitoring system will automatically warn and start filing to remind our monitors to pay attention to this person......"

"I know—do you have any news that you've monitored?"

On that day, our surveillance system noticed that someone was sending out an email through the school's Internet with a large number of photos...... At that time, the system did not give an alarm, and our monitoring personnel did not pay attention to it, and did not intercept it at the first time. Later, by chance, when the network monitor was reviewing, I found out that something was wrong -- the email contained a large number of photos of the scene of our case, and the email was written in English, and it was accompanied by a detailed description of the case in English, giving a detailed description of the case -- and because the whole email was in English, it did not touch our monitoring system.

Then, we started the tracing process, only to find out that the email was sent to a US IP address in the US state of Virginia. ”

Xu Yan hesitated: "It's just an email, it doesn't mean anything, does it? Could it be that a student from our school happened to pass by the scene of the murder, took a photo, and took it out to brag and show off? This kind of possibility, there should be, right?"

Huang Shan didn't deny it: "Which hairy child who doesn't know the height of the sky and the height of the earth goes out to brag about these photos, this possibility is indeed there." But I don't think that's the case -- the email was very problematic. ”

"Brother Huang, tell me about it?"

"The letter was written in English, we found someone to translate it, and the translator said that the sender's English was of a very high standard, and he must have lived abroad. Moreover, his words to describe the scene of the murder are very professional, clear and meticulous - I don't know English, but I have read the translation of the letter, and I feel that the other party should also be my colleague, and he speaks very methodically - to put it mildly, many of our criminal police officers are not as good as others in writing investigation reports, and I will not believe it if you say that this is a joke by a naughty student, this is definitely a professional work from a professional, and the other party has a very high standard. ”

Hearing what Huang Shan said seriously, Xu Yan also became serious: "This can be regarded as a piece of evidence - but, even if this email is very professional, it doesn't prove that the sender is a spy, right?"

Huang Shan took a long time: "We have a second piece of evidence -- we found that this email was involved in a case, and our network supervisor immediately traced the other party's IP address to confirm the identity of the other party." But I didn't expect that. Tracing past IPs is a fake -- well, the network is too complicated. I don't really understand, anyway. The people in the network monitoring team told me that in order to disguise their sending address, the other party used 5 layers of fake IPs and proxies to disguise his real IP, and if it wasn't for the port of our monitoring on the campus server, we really couldn't be sure that this letter was sent by our school.

How about it, brother, I feel a little interesting, right? Think about it, if ordinary people contact foreign friends, can they be so cautious? Do you have to use so many means to cover up your IP? It can be seen that this guy is a thief. It's even more suspicious!"

Huang Shan said this, Xu Yan also agreed--for no reason, who would use so many fake IPs and fake addresses for no reason? If people who don't have ghosts in their hearts just send an email, can they use it so sneaky?

Huang Shan continued: "Moreover, at the end of the email, the sender said that he believed that a series of murders occurred on the campus of Shudu University in Jincheng City, Shudu Province. It should be classified as a kind of murder case secretly known as the 'F' virus rage case by the Chinese government. But this series of murders is obviously different from other 'F' virus type cases, this is a new and specific species, which is a great threat to human security. At present, the Chinese government has no good way to deal with it...... This situation should be taken seriously and prevented by the federal government......"

Listening to Huang Shan's narration, Xu Yan's brows gradually frowned - the matter has come here. Even if you don't need Huangshan to explain, Xu Yan also understands where the problem is: even now. For the common people in China, the "F" virus is crazy. This is still a confidential term. Ordinary people can't come into contact with this term, and since the other party knows this very well, there is a good chance that his identity is an intelligence agent sent from abroad.

He nodded: "In this case, there is indeed something wrong with this person -- even if he is not a professional spy or an amateur spy, he should definitely be arrested! However, I am strange, what does the United States want to do by planting spies in our Shudu University? We are not a military base or an army, we are just a university. ”

Huang Shan corrected him with a very serious expression: "Brother, you don't know anything -- although our Shudu Province is located in the southwest, it was an important town in the country's third-line national defense and military industrial construction in those years, and many major military and scientific research projects were in our province.

Shudu University is a well-known brand-name university in China, and it is also the scientific research base with the strongest comprehensive scientific research strength in Southwest China, undertaking several major national-level research, such as the latest generation of fighter engine metal synthesis research projects, the controllable nuclear fusion project in cooperation with the Third Academy, and the room temperature superconductor project of the Fifth Academy...... Many of our projects in Shudu have very important significance and practical applications in military and people's livelihood, and the research of some projects is even at the forefront of the world. It is normal for the Americans to want to find out about the progress of our research on these projects and to plant spies in our place. ”

Xu Yan's face was slightly hot when he heard Huang Shan say - he was so ashamed, as a student of Shudu University and an intelligence officer, he didn't know anything about the situation of his alma mater - this was also because Xu Yan studied liberal arts, and he usually didn't care much about the situation at the Institute of Psychological Engineering, so he couldn't have imagined that in this ordinary campus, which he thought was uneventful, he would undertake such a major national project, carry out amazing research topics, and even provoke spies from the United States!

"Brother Huang, I'm really embarrassed, I'm studying at Shudu University, and I'm in the intelligence industry, but I don't know anything about this kind of thing...... I'm ashamed. ”

"It's nothing, let's do public security, all kinds of things, we have to know a little bit about everything. Because I participated in the comprehensive management meeting of the Municipal Legal Committee a while ago, it introduced several key security areas in the city...... It mentions several projects that are being studied in Shudu University, which are major projects at the national level, and I paid attention to them at the time, so I remembered - how about it, brother, this case is a bit of a mess, right?"

"Well, did you find out later? Who sent that email?"

Huang Shan spread his hand: "This ...... Our monitoring team, their mission is to prevent someone from leaking information about the case, but to track down spies, such a lofty task...... This and this...... We can't afford it. Huang Shan laughed dryly, and he lowered his voice: "Actually, we don't really want to get involved in catching spies. ”

"Ah, why?"

Huang Shan sighed: "The affairs of your intelligence department are too troublesome! Which of your intelligence departments and national security is a fuel-efficient lamp? Everything that has something to do with you is extremely troublesome! Originally, we were thinking that it would be better to have more than one thing and to hand over this clue to the national security in the city, but it was only when I met my brother tonight that I suddenly remembered that counter-espionage seems to be your task as well, right? This credit should be given to you rather than to be given to the national security in the city, but to you, brother?

Huang Shan was so enthusiastic that Xu Yan didn't know what to say -- if he talked about killing monsters, Xu Yan was still a little confident, but how to get this job of catching spies? Should he take it?

Fortunately, Xu Yan already had experience - he asked Huang Xi if he was indecisive about internal affairs. He called Huang Xi up with a phone call, and then briefed her on the situation. Knowing that the Jincheng police had important clues about the espionage case and wanted to hand them over to the Ministry of Intelligence, Huang Xi's eyes immediately lit up and blurted out: "Okay! Director Xu, this is a good thing, let's take it!"

Since the insider Huang Xi said this, Xu Yan was also indispensable, he nodded and smiled and said: "Okay, since this is the case-Captain Huang, then I will be ashamed to accept this-this, it won't cause you any trouble, right?"

Huang Shan laughed: "How can there be trouble? This kind of case, we hand it over to the local national security is also a handover, and the transfer to you is also a handover, it is all the same, and it makes no difference to us." By the way, I'll take you to the network monitoring team on the third floor to meet their person in charge, and I'll give you the clues. ”

Then Huang Shan led Xu Yan and Huang Xi up to the third floor - here is also a large computer room, in stark contrast to the chaos of the monitoring room on the second floor, this room looks very neat, and the room is neatly placed with more than a dozen computers. The lights were bright, and there was a low hum in the room, it was the sound of the exhaust fan changing the air, several police officers were working in front of the computer, someone was watching something intently, someone was typing quickly, and the room was filled with the sound of ticking fast and rhythmic typing, and the atmosphere seemed very peaceful—if it weren't for the police officers in police uniforms in the room, it would be no different from a computer room or a computer reading room in a school.
