Criminal Psychology

The person Su Fengzi found was Ye Yan, a professor of Mathematics Department of T University.

At eleven o'clock at night, Professor Ye hurried to the underground shopping mall with the key to his house.

Most mathematicians have an uninhibited image, and Professor Ye is probably the best among them. He has messy curly hair and a pair of cotton slippers. After he opened the door and came in, he didn't talk much. He threw the keys on the table panting, and asked: "What code do you want to solve?"

Lin Chen glanced at Ye Yanzhi's appearance, and he could almost imagine the ghost-like mood the other party felt when he received Su Fengzi's call. He probably wanted to throw the phone, but when he thought that the caller was Su Fengzi, he could only obediently obey. Get up on the bed and go downstairs to take a taxi.

Wang Chao moved away from the seat in front of the computer, and Jiang Chao's police officers had already sent the "Discrete Mathematics" over.

Ye Yan flipped through the book quickly, glanced at the restored price list on the screen, and said, "Oh, it is indeed the password."

"Professor, are you sure, why did we just look at it, it's all garbled characters!"

"Because you haven't read enough books." Ye Yan said angrily, as if he didn't want to stay longer for a second, he pulled out a sticky note, wrote a few words, then slapped it on the table, and asked: "Is there anything else? I'll go first."

Lin Chen glanced at Su Fengzi, who was leaning against the window as if nothing had happened, still looking at the angry Professor Ye with a faint smile, and said, "Why are you in such a hurry, let's have a late-night snack together?"

"Am I sick, and go to eat supper with you?"

Su Fengzi was probably used to his attitude, so he wasn't angry, but still smiled.

Seeing that Ye Yan was about to leave, Xing Conglian hurried forward: "Professor Ye, please wait a moment, our technicians are still restoring some images, and maybe I will trouble you later."

"Then why did you call me so early?" Ye Yanzhi sat down even though he was very rude.

Lin Chen picked up the sticky note.

There are two short sentences written on it.

[4.10 Home Farewell Dinner]

【Wirwarentotundkonntenatmen.】

Under the dim light, the black and white characters appear more and more blurred.

Although he has a rough appearance, it has to be said that Ye Yan's handwriting is really good.

"Hey, the book is all in Chinese, why did it become English when it was deciphered?" Comrade Chao Chao began to ask questions again based on the principle of asking if you don't understand.

But Professor Ye obviously didn't have the self-consciousness of teaching and educating people. He crossed his arms and said coldly in Su Fengzi's direction: "Am I still in charge of teaching the police how to solve cases?"

"Of course not." Su Fengzi replied.

The atmosphere between these two people was subtly weird. Specifically, as long as Su Fengzi was around, the atmosphere would not be normal.

Lin Chen looked at the two sentences translated by Ye Yan, and handed the note to Xing Conglian.

"What date did you take the first one?" Xing Conglian asked.

"April 4." Dynasty answered very consciously.

"What about the second rule?"

"April 4th, good luck, boss, they cleared the venue on April 10th, that was the last sentence they left before clearing the venue."

"What do you think?"

Lin Chen listened to Xing Conglian and asked him suddenly, and after a moment of contemplation, he slowly said: "The first one is easy to understand, it's more like a schedule. On April 4th, the itinerary for April 8th was arranged. Home should be The venue, referring to their usual meeting place, then the farewell dinner..."

"It's more appropriate to translate it into a breakup meal." Xing Conglian took out his mobile phone again and called Jiang Chao: "Lao Jiang, let your subordinates check the whereabouts of the six deceased on April 4 to see if there is any intersection." point."

"The second article..." Lin Chen turned his head and asked Xing Conglian naturally, "What do you mean?"

"In German, it should be a poem." Xing Conglian said.

"I rely on it to be poetry, it's so high-quality and literary!" Wang Chao raised his head from the screen again, and interjected, "Isn't this a disease, if you put a lot of effort into encrypting a poem, if you write it directly, no one will doubt it, okay? "

"It's a different feeling." Lin Chen interrupted the boy.

Not only Xing Conglian, but even Ye Yan looked at him suspiciously.

In the underground at night, there was no sound of footsteps.

Lin Chen said softly: "It creates a beautiful illusion, a code word that everyone keeps silently chanting in their hearts, and it will give everyone extremely powerful power."

After dinner, before death begins, recite silently and keep in mind.

"We are dead, but we can breathe."

Xing Conglian's voice was deep and melodious, like a cello, echoing in his ears.

Lin Chen froze for a moment before realizing that he was talking about that poem.

Not obsessed with the intention of death in the poem, Xing Conglian entered keywords into his mobile phone, and quickly found the full text.

"Memories of France"

Reminisce with me, the sky of Paris, the great colchicum...

We go to the flower girl for hearts:

Those hearts are blue and bloom in water.

It's raining in our room,

Mr. Lesson, a neighbor, came in, a thin man.

We played cards, and I lost my eyeball;

You lent me hair and lost it too, he beat us.

He went through the door, and the rain chased after him.

We are dead, but we can breathe.

The author of the poem is Paul Celan, a suffering Jewish poet.

"What does this mean?" Ye Yan also took a look and couldn't help asking.

Lin Chen shook his head, a little speechless.

Anyone who has read this poem can appreciate the cool and beautiful artistic conception about death in it.

For those students, it was so attractive, death is not bloody, it is so beautiful.

This reminded him suddenly of the scene when his little junior sister jumped from the blue to transparent sky, she was so happy, as if death was just another form of life.

As the mobile phone was passed from person to person, Xing Conglian held a cigarette between his fingertips and looked at him with darker green eyes: "This poem must have meaning."

That was the last sentence left by the organization to the believers before the venue was cleared. Apart from encouraging and inciting, it must have symbolic meaning.

Of course Lin Chen knew that what Xing Conglian wanted was to deduce from the poem an exact address where the students would end their lives at 18:00 tomorrow.

But the problem is that the intentions in poetry are complex and changeable. What's more complicated is that different people have thousands of understandings of the same poem.

We die, but we can breathe...

So, what is your understanding?

"Buy a heart, or is it blue? The heart is blue, floating in the water? The water in spring is green, and the only blue is sea water, but Yongchuan also depends on the sea..." Can you feel this kind of atmosphere? , and kept talking, only the dynasty, "Playing cards? Is there a card contest in the university town recently? There shouldn't be any, Mr. Lai Song, the neighbor... The rain is chasing him... Who is he?"

The boy kept asking questions, and the captain of the criminal police couldn't help it, so he slapped him on the back of the head.

"Let's use the elimination method first." Lin Chen paused, and said to Wang Chao, "Call out the topographic map of Yongchuan University City."

"Come on!" The young man raised his hand and pressed the keys, and a gray 3D satellite image spread out, "But why do you think you will be in Yongchuan University City, Chen? Should we focus on Yongchuan University first?"

"Now it seems that it is unlikely that the incident will happen at Yongchuan University tomorrow. If I were the final planner, I would definitely use the first two times to attract the attention of the police and arrange the final highlight in a place that everyone did not expect. ..." Lin Chen said, looking at Xing Conglian, but found that the other party just frowned and thought deeply, without any response, so he continued, "Since the primary purpose of the mastermind behind the scenes is to conduct live broadcasts to make money, then we can rule out all unscrupulous Surveillance or surveillance coverage is relatively weak areas."

Dynasty quickly grayed out all no-surveillance areas.

"In fact, public areas are easy to talk about, but many school classrooms have cameras, what if they rush in and attack the teaching buildings?" Wang Chao said worriedly, looking at many areas that were still bright.

"Since the object of their hatred is the ordinary classmates around them, they will inevitably choose a crowded place where students gather relatively..." Lin Chen paused, and said to Wang Chao, "Please sort out a list of students from various universities in the university city tomorrow. Give me the activity sheet."

"It's been sorted out." Wang Chao took out a piece of paper from his schoolbag, and said with a smile, "Boss told me to do it, so be prepared!"

Lin Chen looked at dozens of activities, large and small, on the A4 paper, and finally understood the pressure of Xing Conglian.

Probably long before this, Xing Conglian had already considered the issue of suspending various activities and monitoring, but even if group activities on campus can be suspended, there are still classrooms, cafeterias, libraries and other crowded places, and the entire university It is impossible for the more than [-] students in the city to disappear without a trace overnight.

Lin Chen stared at the satellite image, feeling a little dazed for a moment.

He suddenly listened to Xing Conglian and asked him: "What is the most dangerous and uncontrollable situation in your imagination?"

"You want to ask, if it were me, how would I kill the most people in this situation, right?"

"You can understand that."

"They are a group, and only group activities can make them feel the short-lived and extremely powerful power..." Lin Chen took a deep breath and said, "I will choose a closed place that cannot be breached by outsiders in a short period of time. Carry out the massacre."

After he finished speaking, no one in the shop spoke anymore.

A rotating display stand is still turning gently, and the crystal ornaments reflect colorful light.

"Then you can exclude all open places." Xing Conglian took a pen, crossed out all the outdoor activities on the paper, and continued: "It's unlikely that the cafeteria is too crowded, unless there are guns, small Crowds have a hard time controlling students that are several times their size, and..."

"The cafeteria is not elegant and beautiful enough." Lin Chen said.

"Killing must be done gracefully, so it must be accompanied by a BGM!" Wang Chao said angrily.

"Since it needs to be elegant and beautiful, it is obviously not beautiful enough for someone to resist..." Xing Conglian seemed to think of something, and asked Lin Chen, "How likely is it that they will kill according to the content of that poem."

"Poetry has existed for a long time. If it is a code word or a slogan, then they should hope that the final feast of killing can be in line with the artistic conception..." Lin Chen thought for a moment, then suddenly looked at Xing Conglian, "You just said control? "

Xing Conglian raised his eyebrows, obviously thinking the same thing as him.

The two suddenly looked at each other, but didn't speak. Comrade Chao Chao became anxious, "What's wrong with the control? How do they control innocent students?"

"Civilian..." Lin Chen looked at Wang Dynasty and said, "You can find a photo to see."

Hearing this, the young man quickly entered keywords in the image search box. He looked at the flowers that instantly covered the entire screen, and after a while, he said numbly, "This is, a blue heart?"

"Colchicum is roughly pink, but when the light is dim, it will appear blue-purple." Lin Chen explained.

"So, they plan to kill in the evening?" Wang Chao swallowed, "But what is the blue heart floating in the water..."

"Colchicine is very toxic, and the lethal dose is about 0.8mg/kg." Lin Chen said lightly, "But it is relatively bitter, and a certain dose will kill you, so its effect should still make the students who eat it by mistake Weakened and less able to resist."

"Poisoning... Poisoning?" Wang Chao was so frightened that he almost exploded, "Damn, what should I do? Could it be that they will poison the drinking fountains? Do we have to check all the water sources overnight, school classrooms and buckets in the library? Water, and the mineral water that will be distributed at the event site?" But the workload is too much, "What if the problem lies with the source manufacturer of drinking water, and it has already flowed into the market!"

The young man's brain hole was getting bigger and bigger, Lin Chen stopped him: "It won't be so difficult. Let's analyze it. First, we haven't received any reports of colchicine poisoning. Suppose there are a batch of problematic ones. The water source, it has not flowed into the market yet, and the distribution of goods in supermarkets and school water delivery will not work late at night, so we have time to prevent this part of the water source problem." Lin Chen looked at Xing Conglian and said: "Second, If it is a poisoning incident aimed at student activities, it is very likely that the batch of water sources has already been purchased and will only be distributed to students at the right time. It will be relatively difficult to prevent similar free drinks; but the most difficult thing to control is the third point Well, if colchicine is in the hands of members of the organization and they poison it themselves, then the school's boiling water room and the water dispensers in the classroom will all become targets..."

"The third point is okay too, it's scary if the three come together~"

Su Fengzi's voice came from the corner.

"Colchicine is very bitter. Students can easily find that there is a problem with the water after taking a sip, and the poisoning of public drinking water facilities cannot control the amount of drinking of the students. If there is a similar poisoning situation, at most it will be auxiliary It is used to distract the police and create an atmosphere of panic..." Xing Conglian said with a cigarette in his mouth, "The teaching building and library can be ruled out, it should be a targeted attack."

Hearing this, Lin Chen looked again at the list of tomorrow's activities compiled by Dynasty. Although most of the school activities started after class at 05:30, the time limit of [-]:[-] pm could still help them exclude some daytime activities.

If poisoning is to be successful, plenty of drinking water is essential, so knowledge contests, party joining ceremonies, college conferences, lectures can be temporarily ruled out...

What was left was an after-school indoor basketball game, as well as activities at the University A Campus Singing Contest and the Dance Festival at University T...

It circled these three activities with a red pen, and then looked at Xing Conglian.

Tonight, Xing Conglian said very little, especially since just now, he spent most of his time in meditation.Obviously, when it comes to such a difficult decision, even Xing Conglian has some difficulty making up his mind.

In fact, there is still some time before the live broadcast tomorrow evening. If they react quickly and use tough tactics, it is entirely possible to wipe out that organization. Opportunities and dangers will always accompany each other.

For example, the best way to deal with it is to control three specific locations, and the problems of control and police force are easy to solve.

However, once they choose this way of handling, it means that they cannot alert the enemy in advance, and must quietly wait for the other party to act.

It’s just that this kind of waiting puts public safety at great risk. Not only do they have to watch the unknowing students drink the highly toxic liquid and wait for them to be poisoned, but they must also ignore those possible threats to the public. Poisoning of water sources.

During this process, once any casualties occurred, they would not be able to bear the heavy responsibility.

Or, they can also choose the simplest and easiest way to solve the problem: go straight out, smash open the coffee bar across the street, give the middle finger to the surveillance camera, and write down all their speculations.

But the problem is, and then...

Then, maybe the organization will order to stop the action, and the group members will continue to hibernate. It is also possible that there is a second plan within the organization, so they will not be able to guess the location of the next dangerous incident.

Even, the organization can let its members go to a place collectively and drink the highly poisonous water in front of the teachers and students of the whole school.

Corpses are scattered all over the field, mourning all over the sky, so why not feel happy?

"We can't take risks." Xing Conglian finally spoke.

Lin Chen didn't expect that Xing Conglian's decision was actually like this?

"Is there any way to change the will of this group before six o'clock tomorrow night?"

He listened to him asking very, very seriously.
