Chen Xiangyang, Guo Na, and Zi Yan heard Yu Fan say that they had found a ignition technique, and their eyes widened with excitement.

"Oh? What do you know? Let's talk about it. The voice was unfamiliar, the voice was strong and deep, everyone looked in the direction of the voice, this is a middle-aged policeman, wearing a straight police uniform, tall and big, looking very energetic, also very mighty, is striding forward.

Zi Yin hurriedly greeted him and reported to the man: "Hello Director Jin, they are comrades from the XA City Bureau, they happened to come to us to handle the case, their team is especially good at dealing with experts in chemistry and psychology, and it just so happens that they are also willing to help, so I invited them to take a look," Then, Zi Yin introduced the middle-aged policeman to Yu Fan and them: "This is Director Jin of our bureau, and he has been at the scene since the accident last night." “

Although Director Jin seemed to be very imposing, he was very polite to them: "Hello comrade XA, just now you said that you found a way to set fire?" ”

Yu Fan nodded: "Although it can't be 100% sure, it's basically nine out of ten, come, everyone look at this." Yu Fan took out the original map of the warehouse to show everyone, and everyone came over.

Yu Fan explained to everyone unhurriedly: "First of all, the deceased was not an arsonist. The location of the deceased is in the corner of the warehouse, if the deceased is an arsonist, even if he makes a mistake in arson and sets himself on fire, then his body will definitely appear on the escape route, that is, the route closer to the door, how can he do the opposite and run into the warehouse? Isn't this a suicidal act of rushing into the flames? “

Director Jin listened thoughtfully, and then asked another question: "Then even if the deceased is not an arsonist, shouldn't he flee to the door at the first time when the fire catches fire?" Why did they end up burning in the corner? ”

Yu Fan smiled: "Director Jin, you got to the point, this is an anti-human psychological instinct, so why did he make this choice?" ”

Guo Na replied: "Because he can't find an exit?" ”

Chen Jieyang retorted: "The warehouse manager is most familiar with the warehouse, okay? How can you not find the direction of the exit? “

Zi Yttrium: "Or is he invisible?" Blindness? “

Director Jin further reasoned: "Or did he encounter some accident that made him unable to see the road and unable to distinguish the direction?" ”

Everyone turned their attention to Fan, which is equivalent to Fan announcing his answer.

Yu Fan looked up at the sky, the sun in the sky loomed in the floating ashes, Yu Fan said slowly: "Sometimes, what can bring us light will also bring us into endless darkness. ”

Everyone was surprised. Yu Fan pointed to the lamp in the original photo of the warehouse in his hand again, and said: "The reason why the warehouse keeper lost his way and the cause of the fire is this one - an incandescent lamp!" ”

Everyone got closer to the photo, but they didn't understand what Yu Fan meant.

Yu Fan continued to explain: "I only need to do a little bit of tricks on this incandescent lamp in advance, and it can become an automatic timer detonator!" Yu Fan gestured as he spoke.

Yu Fan gave Guo Na a thumbs up approvingly, and Guo Na stuck out his tongue at Chen Jiaoyang with some pride.

Yu Fan continued: "Now, I put the timed igniter bulb back on the lamp, and I can wait for the time to come. ”

Zi Yttrium: "What time?" ”

Yu Fan didn't answer immediately, he walked outside the warehouse, began to imitate the behavior of the storekeeper, and said to himself: "After I change shifts at 10 o'clock in the evening, after a little rubbing, I will start today's routine patrol, and when I get to the food warehouse, the time is about 11 o'clock." While saying that, Yu Fan pretended to make a watch action, although Yu Fan was not wearing a watch.

Yu Fan continued: "I confirmed the time and filled out the registration form in my hand. So I opened the door to the storeroom, and it was so dark that I couldn't see anything. Saying that, Yu Fan made a gesture of pretending to open the door, and then pretended to stretch out his head to look inside. Because it was so dark that I needed to turn on the light, I fumbled for the switch on the wall. Every sentence, Yu Fan immersed himself in restoring the actions of the warehouse keeper at that time.

Yu Fan: "I finally touched the switch, I turned it on." That's when ah!!! Yu Fan shouted so loudly that Chen Jieyang next to him trembled back. The light bulb suddenly exploded!! I didn't have time to react, the glass shards pierced into my eyes, I couldn't help but touch my eyes with my hands, but this aggravated the wound of my eyes, I was pushed to the ground by the power wave of the explosion just now, I couldn't open my eyes, I couldn't tell my direction, I felt as if my side was burning, I opened my eyes with all my strength and could only see a fire around me, I knew that things were wrong, I struggled to escape from here, so I wanted to stand up with something, but I pulled down the shelves, this warehouse is full of puffed food, This made the explosion and the flames spread more easily, and I felt that the heat in my body was unbearable, and I struggled like crazy, but the more this happened, the more chaotic the storeroom became, the bigger the flames, and I inhaled too much carbon monoxide gas from combustion, and my mind became less and less conscious. You can only rely on instinct to find the safest, safest place, not to be so miserable. After speaking, Yu Fan curled up in the corner where the deceased finally fell.

Yu Fan came back to his senses. Everyone also looked at Yu Fan dumbfounded, not knowing if it was the ashes in the air that made everyone uncomfortable, or if everyone wanted to say something, everyone licked their lips involuntarily, but no one spoke.

Director Jin broke the silence and said to Yu Fan: "This comrade of XA. As he spoke, he looked at Zi Yttrium, and seemed to ask Zi Yttrium what Yu Fan's name was.

Zi Yu hurriedly explained: "Special consultant of XA City Bureau, psychochemist, Mr. Yu Fan. ”

Director Jin reorganized the language: "Expert Yu, what you just said makes sense, so in your opinion, what should be done next?" ”

Yu Fan: "It seems that this case can be defined as a premeditated vicious arson case. Next, I hope that you will go to the relevant people to take a note and see if they can provide any clues. ”

Zi Yan said: "Last night, we had already made a record of the surrounding people overnight. ”

Yu Fan: "Please do it again." According to the statistics of human psychology, people at night, especially on the night of this frightening fire, the masses will be restless, feel afraid and afraid, and it is easy to miss important clues, and during the day, people's hearts have a strong sense of security and clearer thinking. ”

Director Jin also ordered: "Listen to the experts, organize people, and do it again!" ”

Zi Yan said firmly: "Yes! Roger that. ”
