Ren Yi stared straight at his eyes: "You mean, Zi Yan is in the venue?"
"It may not be Ziyan, Ziyan has so many believers, I'm afraid I won't take the risk myself." Gong Yingxian analyzed, "There are currently six radio stations and one Internet station live broadcasting this concert. In order to ensure the stability of the live broadcast signal, The venue will limit the flow of other satellite signals, which means that it is impossible to control the bomb remotely. Moreover, if we use a signal jammer to block all signals, the bomb will only have a timing function. In this way, Zi Yan will lose the future. He will not leave such a loophole in the control of the bomb's early detonation, so there must be a person on the scene, even if all signals are blocked, the bomb can be detonated manually."
"Manually? Doesn't that mean that that person is doomed to die?" He Gu frowned, "I listened to your conversation, and it feels like this is an X cult organization."
"You guessed right." Ren Yi said coldly, "Many cases that happened in the past six months are all related to them." Thinking of the experience of these months, those innocent people who died in vain, firefighters who died or were injured, and policemen , doctors, as well as the pain left to the family members and the panic of the general public, Ren Yi gritted his teeth with hatred for these perverts.
"In this way, in order to ensure that one person can detonate all the bombs, the first one to explode must be able to cause a chain explosion." Gong Yingxian looked at He Gu, "This is better realized on the equipment system, right."
He Gu nodded: "It's just that the scope has not been narrowed enough to be able to be found in..." He looked at his watch, "It will be found within forty minutes. Many piping systems are spread throughout the venue."
Gong Yingxian glanced at the phone: "Sister Yan is here, Captain Zhang is also making progress, let's go there first and collect the clues."
The three of them came to the meeting room, which had become the emergency combat command.
Qiu Yan waved at them: "Come here, the surveillance has discovered it."
Tan Haochun, who was sitting in front of the computer, turned to greet them: "Hi, Dr. Gong, Captain Ren."
"What did you find?"
Tan Haochun's fingers tapped on the keyboard quickly, showing them a fast-forward screen.
Several people stared at it for a long time, but the picture didn't seem to change much.
"what is this?"
"This is an example. It is between 9:30 p.m. and 10:00 p.m. The pictures of several surveillance cameras, they seem to be unchanged, as if no one passed by, but they are actually frozen."
Gong Yingxian frowned and said, "The system was hacked a long time ago."
"Of course, otherwise how would they get the design drawings of the venue. Now Captain Zhang and his team are watching all the surveillance videos in a week at the highest speed. Looking at them in reverse chronological order, they can see that it was four days ago, and they haven't found anything unusual yet. " Tan Haochun grabbed a large handful of French fries and stuffed them into his mouth, then secretly glanced at Qiu Yan, "I'm sorry, I have to eat when I'm nervous."
Qiu Yan patted his head: "Continue."
"I analyzed that there are no traces on the monitoring. There are two possibilities. One is that the monitoring has been tampered with, and the other is that they haven't seen it yet. The longer the time goes, the less likely the second possibility is, so I tend to the first. .I have compiled a software that can find out the traces of surveillance modifications, but these surveillances have several T, and this year is bound to be endless. Just now, Dr. Gong said in the group that the criminals are very likely in the venue, so I used This software only ran monitoring for one day today, and it was discovered soon.” Tan Haochun took a sip of Coca-Cola and called up a seemingly complicated data analysis software. Several histograms showed peak values. “Through cross-comparison, It can be seen that the monitoring has been modified from time to time since the beginning of the concert. In order not to arouse the suspicion of the monitoring room, the hacker only selects a part to modify each time, and the modification time is not continuous. According to the position and time of the camera modification by the hacker, A person's trajectory can be depicted."
Tan Haochun's fingers almost flew up on the keyboard. Soon, a floor plan of the venue was displayed on the screen. The lines representing the routes were displayed on the floor plan one by one, and the colors were different according to the time. There were eight lines in total, interlaced with each other. Extended, it seems a bit messy.
Several people stared at the screen in silence.
"It's hard to see the pattern of these routes at a glance, and it's almost impossible for a person to complete these routes in such a time." Gong Yingxian said, "Hackers are using this method to confuse us and cover up the criminals' real trajectories. .”
Qiu Yan said: "But at least it proves that the gangster is indeed in the venue, and his movement trajectory must be within the range of this ball line."
Gong Yingxian pondered: "That's right, and it also proved that the bomb was planted after the concert started, the bomb must have followed the car into the venue."
All the spectators went through security checks, but the cars entering the garage did not.
"And it's the organizer's car." Qiu Yan said, "In order to prevent the audience from going to the backstage to harass the stars after entering the venue, once they enter the venue, they will be completely isolated from other areas and cannot perform activities in the venue. But if it is a concert Relevant staff may not only put bombs in the cars of the organizers, guests, equipment teams, and media teams, and use various equipment boxes or materials to conceal the bombs into the venue, but also use their work certificates to move freely in the venue.”
The security team leader immediately said: "Their cars are separated from the audience's cars. There are more than 200 cars in total, all parked on the basement floor."
Gong Yingxian said: "Immediately take the test strips to test the ion mass spectrometer."
Qiu Yan called Cai Qiang and took a group of people to detect explosives. Nitro-based explosives are the most common type of explosives. As long as the explosives have stayed on a certain object, nitrate, ammonium, and sulfonate ions can be detected in a short period of time with test paper and instruments.
Tan Haochun murmured: "I hope Brother Qiang can catch him as soon as possible."
"Even if he catches people, it will only relieve the crisis of the bomb being detonated in advance." Ren Yi looked at his watch, burning with anxiety, "It's only half an hour, and now there is not enough time to evacuate the crowd."
Tan Haochun let out an "ah", shook his legs nervously, stuffed a lot of snacks into his mouth, and whispered, "I, we must find it."
He Gu pointed at the screen: "Give me a printout of this action trajectory map, I will compare it with the design map, at least some places can be ruled out."
"Okay." Tan Haochun wondered, "Who are you?"
"I'm an engineer in a gymnasium."
At this time, Ren Yi's walkie-talkie rang, and Xu Jin said: "We have checked the structural columns, boiler room, power distribution room, power storage unit and other places, and found no explosives. Sure enough, the gangsters would not put explosives on these targets. It’s a big place, but just in case, we will continue to investigate, what progress has the police made?”
"They should be able to identify the vehicle with the bomb soon." Ren Yi glanced at Gong Yingxian, "We are still eliminating suspicious places."
"Okay, communicate anytime."
Gong Yingxian sat on the side, holding his head in his hands, repeatedly recalling every word Zi Yan said in the video, even the change of tone was deliberating carefully.
Ren Yi looked at Gong Yingxian, who was frowning and pale, and was very worried, but found that he had no place to care.
Qiu Yan walked to Gong Yingxian's side and patted him on the shoulder: "Don't worry, calm down and think about it."
Gong Yingxian nodded.
"Zi Yan...is that person?"
"no."
"Are you so sure?"
"According to Liu Dayong's description, that person has severe obsessive-compulsive disorder, and Ziyan doesn't show any tendency toward obsessive-compulsive disorder." Gong Yingxian said in a deep voice, "Besides, Song Juhan is a young singer. No more than thirty-five years old. Ziyan introduces himself as a "humble" messenger, but he also says that he is conveying the will of God. Subconsciously, he thinks that only God is above him, and he is the representative of God in the world. His words are full of conceit and narcissism. This video of him and the planning of this bombing incident, including the gestures and movements he coordinated with when speaking, all reflect his strong desire for control and performance All kinds of profiles do not match the characteristics of the arsonist back then. The arsonist disappeared for 18 years and even tried his best to cover up his existence. If he were Zi Yan, he would wish that the whole world knew his feat. The mentality of expressing oneself at the center of the world stage and gaining everyone's attention and admiration is a common characteristic of the leaders of Cult X, and it is also one of the sources of their charm. Therefore, the two of them are not alone."
After listening to Gong Yingxian's analysis, Ren Yi gasped.
This intricate crime spanning eighteen years, what kind of terrible truth is hidden behind this thick fog
"What puzzles me now is..." Gong Yingxian pondered, "What standard does Zi Yan use to judge a person as an 'evil' soul?"
This question stunned everyone.
Gong Yingxian said to himself: "Only by starting from the motive can we judge his behavior."
They have never considered this issue before. In the consciousness of normal people, everything that Cult X does is crazy and irrational, and it is difficult for normal people to understand. But now they have to understand.
Tan Haochun said: "Aren't they a coalition of pyromaniacs? Arson itself is their belief."
Gong Yingxian shook his head and said: "Maybe Zi Yan thinks so in his heart, maybe other people think so too, but when Sect X controls people, it must be for a just reason. Zi Yan needs such a reason to unite Groups, and use this reason to brainwash everyone so that they lose their personality and only have group psychology. And groups also need such a reason to constantly find a correct starting point for their behavior. When the outside world strikes them, they will Will use this righteous reason to make excuses for themselves, and then the cohesion will be stronger. Therefore, Ziyan will never say that we kill people for fun, but only say that we use fire to purify evil souls, and repeatedly say, Go on saying it until he himself and others believe it."
Tan Haochun sat up straight: "I called out all the arson cases in the past ten years to see if I can find the cases committed by this organization, and maybe I can find their criteria for judging evil spirits."
"It's impossible for them to hide from people for so long. I think the real formation of this organization has something to do with the spreading power of Seraphim's website." Gong Yingxian said, "So, narrow the scope to five years."
