Criminal Psychology

It was raining heavily outside the window. Although Xing Conglian couldn't hear what Xing Conglian was saying, the vibrating notification of the mobile phone quickly grabbed Lin Chen's full attention.

He lowered his head, and in just a few seconds, countless messages flooded into the WeChat group instantly, and new messages continued to appear one after another

[Teacher, teacher, and students are leaving, there is no way to stop them. 】

[When will the electricity come? 】

[Starting to tear up the test paper. 】

【I'm so scared too...why did the power go out all of a sudden? 】

[May I ask what's going on, when will the call come? 】

【Rely on me, it's so scary. 】

[Can you really not let them go? 】

[Our door is blocked, what should I say next? 】

……

The screen showed a dark green light, Xing Conglian came over, took a look, and said, "Tear up the test paper... Are these kids crazy?"

"But it makes people's blood boil, doesn't it?" Lin Chen hugged his arms and looked coldly at the dark night in front of him.

"passionate?"

Lin Chen put his finger on his lips, signaling Xing Conglian to keep silent: "Listen."

Outside the window was a vague scream, sometimes high, sometimes low, and sometimes completely silent, as if there were no sound at all.

"You mean screaming?" Xing Conglian asked uncertainly.

As soon as he finished speaking, there was a loud bang suddenly in the rainy night.

The sound was too loud, as if something heavy had fallen from the sky, and the tail sound had some metal-specific vibrato.

Lin Chen shivered and looked into the depths of the night, but the distance was still rain except for the rain, and the unextinguished street lamps were like duckweed under the heavy rain.

The torrential rain, accompanied by roars, came rushing toward us.

The sudden heavy object obviously reminded the children of the incident of jumping off the building today. Those cries became more manic, like underground ghosts, trying to overturn the soil and rush into the world.

His cell phone began to vibrate non-stop, and one after another of text messages poured in one after another like a spell calling for his death.

[The door can't be stopped soon! 】

[Did someone jump off the building again? ? 】

[Someone is calling for help! ! ! 】

【How to do? 】

【what to do? ? ? 】

[It's okay to let them go, anyway, the power is out! 】

[I really can't stand it anymore! 】

……

The characters on the screen flowed crazily, and Lin Chen almost said to himself: "Yes, collective unconsciousness."

After he finished speaking, he glanced at Xing Conglian and rushed out without even having time to explain.

[Be sure to guard the students and prohibit any students from leaving. 】

[Tell the students that it is raining when they go out, so wait for a while to see if there is a call. 】

The short three-story building is so long, and he typed words one by one while running.

The moment he stepped out of the eaves, the torrential rain instantly soaked him all over, and there was a huge pulling force behind him, and Lin Chen was pulled back abruptly, stopping in his tracks.

"Is it useful for you to rush out now, calm down." Xing Conglian held his hand tightly and said word by word.

"I'm very calm!" He panted heavily, and the rain was now as strong as hailstones. "Power failure, falling objects, someone is instigating students to rush out of the classroom!"

"You mean someone wants the students to riot? But you can control the crazy students by yourself. I doubt it. Now tell me, if the students rush out of the classroom now, what is the worst consequence?" Xing Conglian His voice was as calm as ever, and he wasn't even breathing in the slightest.

"Casualties, stampede..." Lin Chen's thoughts turned, and countless possibilities swirled in his mind.

"Stairs?" Xing Conglian said suddenly.

"Yes, the stairs. I'm afraid someone has tampered with them."

"Okay, I see, you go back and stay now, I will send someone to check the stairs."

Lin Chen was about to speak, but suddenly his shoulders were heavy, and Xing Conglian pressed his hands on his shoulders, and said in an extremely calm voice: "It is also possible that someone set up a trick to lure you to appear, so you give the order here, It's the best choice."

After Xing Conglian finished speaking, he let go of his hand and ran to the depths of the rainy night in his place.

Lin Chen's vision was blurred.

"I understand."

He said this to Xing Conglian's back.

The sound of rain continued, Lin Chen sat back on the stairs, although dripping all over his body, he couldn't feel the slightest bit of coolness.

Thunder and lightning still passed by alternately, but maybe Xing Conglian's figure running into the rain curtain at the end was too reckless, and there was a strange and extremely quiet feeling in his heart.

He suddenly felt that the heavy rain seemed to be favored by God.

【The teacher is in better condition now. 】

[Damn it, it was too dangerous just now, it was crazy. 】

[Our class tore up all the test papers, do you believe it? 】

[Fortunately, it was raining, and they were still a little hesitant, otherwise they would definitely not be able to stop it. 】

……

Lin Chen took a deep breath, and his breath was full of the coldness of a rainy night.

He wrung out his shirt, wiped his hands, touched the screen, and typed:

[Students who want to leave are notified that it is raining too much now. If there is no call after 10 minutes, they will go downstairs in an orderly manner from class [-] to class [-]. 】

----

When Xing Conglian rushed to the downstairs of the teaching building, he saw broken paper scraps all over the floor.

There are still scattered pieces of paper upstairs, mixed with rainwater and falling down.

However, most of the students' shouts had stopped, and the entire dark building stood quietly and empty in the rainy night.

Xing Cong thought about it, probably Lin Chen's arrangement played a role.

The security guards of the school had already heard the news, and there were also several figures dashing through the rain curtain in the distance. They should be the police officers he called Jiang Chao to find just now.

Because of the many suicide cases, he had already had photos with most of the security guards. He didn't even need to show his police badge, but just wiped the rain off his face, and some security guards had already called out his name.

"Captain Xing, what happened to Captain Xing?"

Xing Conglian looked up at the floor. The students were tested on the fifth floor, and there were still people sticking their heads out to look at something. The teaching building had two staircases, east and west, and time was tight.

He pointed to the five security guards in front of him, and said solemnly: "Have you seen this building, five of you, check the first to fifth floors of the east staircase separately, try your best to complete the inspection within 5 minutes, and the rest follow me... ..."

As he spoke, he said to the last security guard left behind, "Give me the walkie-talkie and headset."

In the corridor, only the emergency light was on after the power was cut off. Xing Conglian stood on the bottom floor and looked up. The entire corridor was shrouded in vague dark green light.

The sound of hurried footsteps sounded behind him, Xing Conglian quickly turned around, and made a silent gesture to the three police officers who rushed over.

"Check the stairs in 5 minutes, mute the phone, try to keep the sound as low as possible..." After he finished speaking, the phone vibrated slightly.

Lin Chen sent a text message as if pinching the time.

[If there is an incoming call in 6 minutes, the student union will start to leave, be careful. 】

Xing Conglian put away the phone, turned on the flashlight that came with the phone, and bent down to touch the ground.

The stairs were dimly lit, and the ground was extremely wet and slippery due to the rain. He grabbed the handrail and walked upstairs.

The armrest was very stable to the touch, and he shook it vigorously again, but there was still no problem.

A drop of cold water fell on his forehead. Xing Conglian raised his head and saw fine droplets of water condensed on the iron railing. He frowned and lowered his head quickly. Next, it is even more blurred.

He lowered the light of the flashlight, and there was something vaguely falling on the edge of the stairs.

He walked a few steps, squatted down, and realized that they were actually two tiny plastic beads.

One is yellow and the other is pink.

At this moment, a suppressed and tense voice came from the intercom.

"There are nails on the ground, everyone be careful."

Although there was no wind, in an instant, Xing Conglian seemed to feel that the air around him was so cold that it was about to freeze.

Nails, plastic beads... if you add students running down the stairs...

He seemed to see blood all over the floor, and heard the painful screams of students lingering in the corridor.

After he stabilized his breath, he whispered into the intercom microphone: "Be careful, clear the stairs quickly, and leave in 5 minutes as originally planned."

After speaking, he bent down, picked up the two plastic beads on the ground, and sealed them in the evidence bag.

The sound of crackling rain echoed in the empty corridor, listening to the sound of rain, Xing Conglian rarely felt lucky to survive the catastrophe.

---

For the students in the teaching building, tonight was just a small attempt to rebel against the school's occasional brain-dead decision.

Anyway, it's dark, and everyone is making trouble together anyway, the simplest truth is that the law does not blame the public.

Moreover, just tearing off two papers is no big deal at all. Who made the school crazy and called them out to do psychological tests on a rainy day?

Moreover, the efficiency of school affairs was really low, until they left the teaching building one by one, Dianyi still didn't come.

Xing Conglian stood in the dark without an umbrella. He watched the figure of the last student leaving the teaching building safely, and took out his cigarette case and lighter.

"Captain Xing, don't you need to stop the students to investigate?"

the policeman in front of him asked in a low voice.

"Five hundred students, can you stop them?"

Probably because he was really unlucky, he pressed the lighter a few times, but even sporadic flames did not appear.

At the moment, Jiang Chao's police officers were scanning the backs of the students leaving with the eyes of terrorist criminals. Xing Conglian frowned, patted the other party's shoulder, and extended his hand to the other party.

"Captain Xing...I...I don't smoke..."

After being tossed all night, he has completely lost his temper. Like his luck today, if a lighter appears in front of him, he will be called a ghost.

He took out the sealed evidence bag from his pocket, handed it over, and said: "Together with the things you found on the ground, take it for inspection, and focus on fingerprints."

After he finished speaking, he turned and left.

The rain was still falling, it was obviously a spring rain, but when it fell to the end, there was a sense of bleakness.

He was walking under the tree alone, when suddenly, his cell phone started to vibrate again.

On the other end of the phone was Jiang Chao's tense voice.

"Old Xing, the power outage is artificial. I just discovered a simple timed power outage device. It seems that the power will not be restored for a while. Are you okay?"

Perhaps Jiang Chao's voice was so loud that it made the surrounding rain seem a little quieter.

"Oh, it's fine for now."

Xing Conglian glanced at the dim light of the building in the distance, and there seemed to be a thin figure sitting alone at the top of the steps.

He put down his phone and walked to where he came from.
