Lighting a fire for an arsonist? Yu Fan said amazingly.

Everyone looked at Yu Fan very nervously, everyone knew that Yu Fan was not crazy, but they didn't know what Yu Fan wanted to do.

Yu Fan asked Zi Yan: "Zi Yan, can you help me find a big iron basin, I want to put a fire in the central square of the town!" ”

Zi Yttrium swallowed: "Yes, yes, but what are you doing with this?" Why ignition? ”

Yu Fan: "In criminal psychology, it is said that serial arsonists cannot suppress the temptation of flames, they will be forced to be attracted by flames, tonight we are going to do a flame show together, have a bonfire party." First, we can attract suspects to participate in this flame show, and the behavior of such people will definitely show clues, and we can catch him by observing and combining profiles. Second, the burning of the blazing fire will more or less satisfy his desire for flames, which may prolong his next crime! ”

Yu Fan paused for a moment and continued: "This is also a way to no way, the best offense is to defend, don't let our offense stop, when he really has a respite, it will be the day when the town suffers." ”

Everyone understood what Yu Fan meant, hit it off, and began to arrange it in full swing.

Zi Yan summoned his colleagues to find a cauldron and pulled it to the center of the town, Chen Xiangyang, Yu Fan, and Guo Na respectively led people to find observation points to observe the scene, and Chen Wanli borrowed a pseudo base station to send a text message to the crowd near the town, informing them that there was an event in the central square tonight.

The firewood was set up, the gasoline was poured, everything was ready, and the sky was slowly getting dark. At six o'clock, many families have finished dinner, but there are not many pedestrians on the road in the town, probably because there was an arson case just yesterday, and people are still panicking.

However, after all, the family cannot sit down, because people's fears need to be channeled, and the way to channel them is to confide in each other. At half-past seven, people began to come out of their homes one after another, chatting with each other in groups of three or five, and the recent fire was obviously their best conversation.

Many people received a text message from Chen Wanli and gathered in the square. There are more and more people in the square. The people from the town police station also quietly lurked in the crowd.

"Can we begin?" Zi Yan asked Yu Fan.

Yu Fan: "Hmm. ”

A small torch ignited the fuel in the brazier, and the flames soared, and the town should not have had a bonfire party for a long time, because this kind of party has certain safety hazards after all, and it generally requires various approvals, and it is difficult to approve it. Tonight is the first cut and then the prelude, I have to say that Director Jin of the small town police station really helped Yu Fan and them to give them a lot of green lights. Perhaps it is also because Yu Fan's way of doing things is different from tradition, and this Director Jin happens to be a person who is willing to innovate, so he supports it so much.

The moment the brazier was lit, the townspeople couldn't help but let out a "wow".

Ordinary people generally choose to watch from a distance, while arsonists who are desperate for flames will enjoy it up close. Yu Fan observed the crowd at close range, and everyone looked at the flames in a daze.

In fact, there is a psychological explanation for why people are in a daze when they see a flame.

The first thing to explain is what "daze" is. "Daze" refers to being in a hurry, fear, or being preoccupied with the outside world. Daze is a stress response of the human brain to regulate external affairs. People who are in a state of daze, unwilling to think, stagnate in a quiet atmosphere, forget everything.

Since being in a daze is a stress response, there is a corresponding stimulus. In the case of fire, light and heat can stimulate people.

Light affects the human body through the nervous system, and nerve fibers transmit light signals to the visual cortex and other parts of the brain, control the body's biological clock and hormones, and affect the pituitary gland, pineal gland, adrenal gland, and thyroid gland. Through their interactions, the physiological and behavioral rhythms of the human body are generated, reset and regulated.

The common flame in life is orange and yellow, which belongs to the warm color. In this tone, it gives a warm and bright feeling, the person's mood tends to be stable, and the mind is in a relaxed state.

The flame heats up, raising the temperature of the surroundings. In this warm and comfortable environment, the capillaries on the surface of the body dilate, and the blood retained in the periphery increases, while the blood supply to other organs is relatively reduced, including the brain, which first responds to the previous state of ischemia and hypoxia, and begins to become sluggish and coagulated.

But at this time, Yu Fan found a person's abnormality!!

In the crowd standing in front, a man was wearing a black coat and a mask, and his body was shaking. Yu Fan looked carefully and found that the person kept rubbing his hands, but it looked very unnatural, as if it was like a ...... It's like one hand trying to control another hand that is out of control. If you look closely, you can see that this person is constantly taking deep breaths, and his body is very undulating.

Yu Fan hurriedly called in the headset: "I found a very suspicious person here, eight or nine is not far from ten, ask for support." ”

Chen Jieyang said in the headset: "Received, I'll be next to you, come over immediately." In addition to Chen Jiaoyang, everyone else also responded and came to support.

Chen Jieyang found Yu Fan in less than a minute, and Yu Fan pointed to the suspicious discovery to Chen Jieyang with his eyes. At this time, the eyes of the man in black also met Chen Jieyang.

The four eyes are facing each other, even if they are silent, even if they are far away, they can still convey each other's messages. Chen Xiangyang's eyes are the predator, and the eyes of the man in black are the prey!

The man apparently smelled danger and turned to leave. Chen Jieyang was preparing to chase. But!

Unexpected voice!

With a thud, the flames in the center of the square turned into a cloud of white smoke. The fire was extinguished. What's going on?

Everyone present let out a sigh, hey.

Everyone looked towards the center, and it turned out to be a familiar figure, it was the people from Nabo Town who had obstructed Yu Fan in the morning, holding a fire extinguisher to extinguish the flames.

At this time, Yu Fan and Chen Jieyang turned their heads to look in the direction of the man in black, and the man in black was gone, and he escaped into the darkness.

"Is CNMD stupid? Trouble at the right time! Chen Jieyang could no longer suppress the anger in his heart and shouted and scolded.

Everyone gathered around the brazier, including Director Jin. Everyone stared at the mayor and his party with anger. There was a fire in everyone's eyes, and the mayor was surrounded like this, and they were a group of people in their hearts.

When the mayor saw everyone coming, he deliberately raised his voice: "Who set this fire?" ”

"Me!" Everyone yelled, and everyone took another step forward.
