Ren Yi stared straight: "You mean, Zi Yan is in the venue?"

"It may not be Zi Yan. Zi Yan has so many believers, so I'm afraid it won't take risks in person." Gong Yingxian analyzed, "Now there are six radio stations and one online station that are broadcasting this concert live. In order to ensure the stability of the live signal, the venue will limit the current flow of other satellite signals, which means that remote control of bombs cannot be achieved. Moreover, if we use signal shielders to block all signals, the bomb will only have a timing function. In this way, Zi Yan loses the control to detonate the bomb in advance, and he will not leave such a loophole, so there must be someone on the scene. Even if all signals are blocked, they can detonate the bomb manually."

"Manual? That means that that person cannot escape death?" Why frowned, "I listen to your conversation and feel like a X organization."

"You guessed right." Ren Yi said coldly, "The many cases that have occurred in the past six months have all been related to them." Thinking of the past few months, those innocent people who died in vain, firefighters, police, doctors, and the pain left to their families and the panic of the public, Ren Yi gritted his teeth at these perverts.

"In this way, in order to ensure that one person can detonate all bombs, the first one must be able to cause a chain explosion." Gong Yingxian looked at why, "This is better achieved in the equipment system, right?"

Why nodded: "But this range has not been narrowed down to... " He looked at the watch, "It was found within forty minutes. Many piping systems are spread throughout the venue."

Gong Yingxian glanced at the phone: "Sister Yan is here, Captain Zhang has made progress. Let's go there first and summarize the clues."

The three of them came to the conference room, which had become the emergency combat command center.

Qiu Yan waved to them: "Come here, the surveillance has discovered it."

Tan Haochun, who was sitting in front of the computer, turned around and greeted them: "Hi, Dr. Gong, Captain Ren."

"What's the discovery?"

Tan Haochun's fingers quickly tapped on the keyboard, showing them a fast forwarding scene.

The few people stared for a long time, but the picture seemed to have not changed much.

"What's this?"

"This is an example. The pictures of several surveillance cameras are between 9:30 and 10:00 pm. They seem to have not changed. It seems that no one has passed by, but they are actually frozen."

Gong Yingxian frowned and said, "The system was invaded very early."

"Of course, otherwise how could they get the design drawings of the venue? Now Captain Zhang's people are watching all the surveillance videos within a week at the highest speed. In reverse order of time, they all saw four days ago, and nothing strange was found." Tan Haochun grabbed a handful of French fries and stuffed them into his mouth, then secretly glanced at Qiu Yan, "Sorry, I'm going to eat when I'm nervous."

Qiu Yan patted his head: "Continue."

"I analyze that there are no traces on surveillance. There are two possibilities. One is that the surveillance has been tampered with, and the other is that they have not seen it. The more time goes, the smaller the second possibility, so I tend to be the first one. I have compiled a software to find out the traces of surveillance being modified, but these surveillances have several Ts, and this year they will definitely not be able to run. Just now, Dr. Gong said in the group that the criminals are very likely to be in the venue, so I used this software to only run the surveillance for one day today, and soon discovered it." Tan Haochun took a sip of Coke and called out a data analysis software that seemed somewhat complicated. Several bar charts showed peaks. "Through cross-comparison, it can be seen that the surveillance has been modified from time to time since the concert started. In order not to arouse suspicion in the monitoring room, hackers only select parts to modify each time, and the modification time is not continuous. According to the hackers modifying the position and time of the camera, a person's movement 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. Depending on the time, the colors were also different. There were eight in total, extending intersected and extended, which seemed a bit messy.

Several people stared at the screen in silence.

"It is difficult to see the rules of these lines at a glance, and it is almost impossible for a person to complete these lines in these times." Gong Yingxian said, "Hackers are using this method to confuse us and cover up the real trajectory of the criminals."

Qiu Yan said: "But at least it proves that the gangster is indeed in the venue, and his movements must be within the range of this group."

Gong Yingxian thought, "That's right, and it also proved that the bomb was buried after the concert began, and the bomb must have followed the car into the venue."

The audience members were all under security check, but there was no car to enter the garage.

"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, they will be completely isolated from other areas and cannot be moved in the venue. However, if they are relevant staff at the concert, not only can they put bombs in the cars of the organizer, guests, equipment group, and media group, and use various equipment boxes or supplies to cover the bombs into the venue, but they can also use their work documents to move freely in the venue."

The security team leader immediately said: "Their cars and the audience's cars are divided into sections, with a total of more than 200 cars parked on the first floor."

Gong Yingxian said: "Take the test strips right away to detect the ion mass spectrometry."

Qiu Yan called Cai Qiang and brought a group of people to detect explosives. Nitro explosives are the most common ones now. As long as the explosives have stayed on an object, they can detect nitrate, ammonium, and sulfonate plasmas with test strips and instruments in a short period of time.

Tan Haochun murmured: "I hope Brother Qiang can catch someone as soon as possible."

"Even if he caught someone, it would only relieve the crisis of the bomb being detonated in advance." Ren Yi looked at his watch and was anxious. "It's only been more than half an hour, and now there is not enough time to evacuate the people."

Tan Haochun said "ah", trembling his legs nervously, stuffed snacks into his mouth, and whispered: "I, we must find it."

Why point to the screen: "Print a copy of this movement trajectory diagram for me. I want to compare it with the design diagram, and at least some places can be ruled out."

"Okay." Tan Haochunqi said, "Who are you?"

“I am an engineer at the gym.”

At this time, Ren Yi's intercom rang, and Xu Jin said: "We have checked the structural columns, boiler rooms, distribution rooms, electric storage units and other places, and no explosives were found. The criminals did not put the explosives in these large target places, but just in case, we will continue to investigate. What progress has the police made?"

"They should be able to determine the vehicle that brought the bomb soon." Ren Yi glanced at Gong Yingxian, "We are still excluding suspicious places."

"Okay, communicate at any time."

Gong Yingxian sat aside, hugged her head with both hands, and repeatedly recalled every word Zi Yan said in the video, and even the change in his tone was carefully pondering.

Ren Yi looked at Gong Yingxian, who was frowning and pale, and was very worried, but he felt uncomfortable to find that he had no stance of concern.

Qiu Yan walked to Gong Yingxian and patted him on the shoulder: "Don't be anxious, 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 had severe obsessive-compulsive disorder, and Zi Yan did not show any tendency to obsessive-compulsive disorder." Gong Yingxian said in a deep voice, "And, Song Juhan is a young singer. Zi Yan should be no more than thirty-five years old when listening to his songs. Zi Yan introduced himself as a messenger of "humbleness", but said that he was conveying the will of God. Subconsciously, he believed that only God was above him, and he was the representative of God in the human world and was the only one. His words were also full of conceit and narcissism. His video and the planning of this explosion,

Including his gestures and actions when he spoke, he reflected his strong desire to control and express himself. All kinds of profiles did not conform to the characteristics of the arsonist back then. The arsonist disappeared for eighteen years and even tried his best to cover up his existence. If he was Zi Yan, he would wish that the whole world would know his feat. This mentality of standing at the center of the world stage to express himself to the fullest and gaining everyone's attention and worship is a common feature of the leaders of the X Cult and one of their charm. Therefore, the two of them are not the same person."

After listening to Gong Yingxian's analysis, Ren Yi gasped.

What kind of terrible truth is hidden behind this complicated crime spanning eighteen years?

"What puzzles me now is..." Gong Yingxian thought, "What is the standard for Zi Yan to judge a person as an 'evil' soul?"

This question stunned everyone.

Gong Yingxian said to himself: "Only by starting from the motivation can he judge his behavior."

They had never considered this issue before. In the consciousness of normal people, everything X teaches does is crazy, irrational, and it is difficult to understand with normal people's thinking. But now they must understand.

Tan Haochun said: "Aren't they arsonism alliance? Arson itself is their belief."

Gong Yingxian shook his head and said, "Maybe Zi Yan thinks this in his heart, and maybe others think this in his heart, but when X Church controls people, it must use a justification for justice. Zi Yan needs such a reason to gather the group and brainwash everyone with this reason, so that they can lose their personality and have only group psychology. The group also needs such a reason to constantly find a correct starting point for their behavior. When external attacks them, they will use this justification for excuses for themselves and then become more cohesive. Therefore, Zi Yan will never say that we kill people because of fun, but will only say that we are purifying the evil soul with fire, saying repeatedly, constantly speaking until he and others believe it."

Tan Haochun sat upright: "I have transferred out all the arson cases in the past ten years to see if I can find the cases committed by this organization, and maybe they can find their criteria for judging evil souls."
