The person Su Fengzi found was Ye Yan, a professor of mathematics at T University.
At eleven o'clock in the night, Professor Ye hurried to the underground shopping mall with the door key in his hand.
Most mathematicians are unruly, and Professor Ye is probably the best among them. He wears messy curly hair and double-cotton slippers. After pushing the door in, he doesn't say much. He threw the key on the table breathlessly and asked: "What code do you want to solve?"
Lin Chen glanced at Ye Yanzhi's appearance, and he could almost imagine how the other party felt like a ghost when he received a call from Su Fengzi. He probably wanted to drop the phone, but when he thought that the caller was Su Fengzi, he could only obey. Get out of bed and go downstairs for a taxi.
The dynasty stepped aside in front of the computer, and the police officers under Jiang Chao had already delivered the book of "Discrete Mathematics".
Ye Yan quickly flipped through the book, 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!"
"Because you don't read much." Ye Yan said in a good manner, as if he didn't want to stay for a second. He grabbed a note and 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 like nothing else, still looking at the angry Professor Ye with a faint smile and said, "Why are you so anxious, let's have a late night snack together?"
"Am I sick, go to supper with you?"
Su Fengzi was probably used to his attitude, not angry, and 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, maybe I will trouble you later."
"Then why did you call me so early?" Ye Yanzhi sat down even though his mouth was rude.
Lin Chen picked up the note.
There are two short sentences on it.
[4.10 Home Farewell Dinner]
[Wir waren tot und konnten atmen.]
In the dim light, the black and white text became more and more blurred.
Although he is sloppy, I have to say 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 Wang Chao started to ask questions again on the principle of asking if he didn't understand.
But Professor Ye obviously has no self-consciousness to teach and educate people. He hugged his arms and said coldly in the direction of Chao Su Fengzi: "Am I still responsible for teaching the police how to solve cases?"
"Of course not." Su Fengzi replied.
The atmosphere between the two 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 was the first shot taken?" Xing Conglian asked.
"April 8." Dynasty replied consciously.
"What about the second rule?"
"April 10th, good luck, boss, they cleared the field on April 10th, and that was the last word they left before clearing the field."
"What do you think?"
Lin Chen listened to Xing Conglian and suddenly asked him. After thinking for a while, he slowly said: "The first item is easy to understand, more like a schedule. On April 8, the schedule for April 10 was arranged. Home should be The location, referring to their usual meeting place, then the farewell dinner…”
"It's more appropriate to translate it into a casual meal." Xing Conglian took out his mobile phone again and called Jiang Chao: "Old Jiang, let your subordinates check the whereabouts of the six deceased on April 10 to see if there is any meeting. point."
"Article 2..." Lin Chen naturally turned his head and asked Xing Conglian, "What do you mean?"
"German, it should be a poem." Xing Conglian said.
"I'm relying on poetry, and it's very high and literary!" Chao Dynasty looked up from the screen again, and interjected, "Isn't this sick, put a lot of effort into encrypting a poem, and write it directly, and no one will doubt it, okay? "
"This is a different feeling." Lin Chen interrupted the boy's words.
Not only Xing Conglian, but even Ye Yan looked at him suspiciously.
The underground at night was so silent that there was no sound of footsteps.
Lin Chen said softly: "It creates a beautiful illusion, a secret phrase that everyone keeps reciting in their hearts. It will give everyone an incomparably powerful power."
After the dinner, before death begins, recite it repeatedly and keep it in your heart.
"We're dead, but we can breathe."
Xing Conglian's voice was low, and his melodious voice like a cello echoed in his ears.
Lin Chen was stunned for a while, only to realize that he was talking about that poem.
Not obsessed with the intention of death in the poem, Xing Conglian entered the key words on his mobile phone, and then quickly searched the full text.
"Memories of France"
Remember me, the sky of Paris, the great autumn daffodils...
We go to the flower girl to buy hearts:
Those hearts are blue and bloom in the water.
It rained in our room,
The neighbor, Mr. Lesson, came in, a thin man.
We play cards and I lose eyeballs;
You lent me your hair and lost too, he beat us.
He walked through the door, the rain chasing after him.
We are dead, but we can breathe.
The author of the poem is Paul Celan, a Jewish poet who has lived through hardships.
"What does this mean?" Ye Yan also glanced at it and couldn't help but ask.
Lin Chen shook his head, a little speechless.
Anyone who has read this poem can appreciate the cool and beautiful mood of death in it.
For those students, it was so appealing, death wasn't bloody, it was so beautiful.
This reminded him of the scene when his little sister jumped from the blue to the transparent sky, she was so happy, as if death was just another form of life.
The mobile phone was passed from person to person, Xing Conglian held a cigarette between his fingertips and looked at him with dark green eyes: "This poem must be meaningful."
That was the last sentence left by the organization to the believers before clearing the venue. Apart from encouragement and incitement, it must have symbolic meaning.
Of course Lin Chen knew that what Xing Conglian wanted was to deduce an exact address from the poem, the 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 ever-changing, and what's more complicated is that different people have thousands of interpretations of the same poetry.
We're dead, but we can breathe...
So what is your understanding
"Buying a heart, or is it blue? Is the heart blue, floating in the water? The water in spring is green, blue is only sea water, but Yongchuan is also close to the sea..." In this atmosphere, Still talking non-stop, there was only Dynasty, "Playing poker? Is there a poker tournament in the university town recently? Probably not. Neighbor Mr. Lesson... The rain is chasing him... Who is he?"
The young man kept asking, but the police captain couldn't help it, and slapped him hard on the back of the head.
"Let's use the elimination method first." Lin Chen paused and said to the dynasty, "Take out the topographic map of Yongchuan University Town."
"Okay!" The young man raised the keys, and a gray 3D satellite image was laid out. "But Ah Chen, why do you think you will be in Yongchuan University City? Should we focus on Yongchuan University first?"
"It now seems unlikely that the incident will happen at Yongchuan University tomorrow. If I were the final planner, I would definitely use the first two groups to attract the attention of the police, and arrange the final highlight in a place that no one expected. ..." Lin Chen said, looked at Xing Conglian, but found that the other party was just brooding and thinking, and there was no response, so he continued, "Since the primary purpose of the mastermind behind the scenes is to make money through live broadcasts, then we can exclude all unmonitored Or surveillance coverage in areas with relatively weak coverage."
Dynasty quickly turned all unmonitored areas gray.
"Actually, the public area is easy to say, but many school classrooms have cameras. What if they rush in and attack the teaching building?" Wang Chao said worriedly as he looked at many areas that were still bright.
"Since the object of their hatred is the ordinary classmates around them, they will definitely choose places where students are relatively crowded..." Lin Chen paused and said to the dynasty, "Please organize a list of the student activities of various universities in the university town tomorrow. Give me the table."
"It's been sorted out." Chao Dynasty took out a piece of paper from his schoolbag and laughed, "The boss asked you to do it, so be prepared!"
Lin Chen looked at the dozens of activities on the A4 paper, large and small, and finally understood the pressure of Xing Conglian.
Probably long before this, Xing Conglian had already considered the issue of suspending various activities and control, but even if group activities on campus could be suspended, there were still classrooms, cafeterias, libraries and other crowded places, the entire university. There are more than 200,000 students in the city, but it is impossible for them to disappear without a trace overnight.
Lin Chen stared at the satellite image, and was a little lost for a while.
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 collective activities can make them feel the short-term and incomparably powerful power..." Lin Chen took a deep breath and said, "I will choose a closed place that outsiders can't break through in a short time. massacre."
After he said this, no one in the shop spoke any more.
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 outdoor activities on the paper, and continued: "It is unlikely that the cafeteria is too crowded, unless there are firearms, small Crowds have a hard time controlling their students several times over, and…”
"The cafeteria is not elegant and beautiful," Lin Chen said.
"You have to kill people with grace, do you need a BGM!" Chao said angrily.
"Since you want to be elegant and beautiful, then someone resists, obviously not beautiful enough..." Xing Conglian seemed to think of something and asked Lin Chen, "How likely are they to 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 killing feast can fit the mood..." Lin Chen thought for a moment, then suddenly looked at Xing Conglian, "Did you just say control?"
Xing Cong raised his eyebrows, obviously thinking of the same place as him.
The two suddenly looked at each other, but did not speak. Comrade Wang Chao began to worry, "What's wrong with the control, how can they control the innocent students?"
"Qiu Shui Xian..." Lin Chen looked at Chao Dynasty and said, "You can find a photo to see."
Hearing the words, 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 blankly, "This is the blue heart?"
"The autumn daffodils are generally pink, but when the light is dim, it will appear blue-purple." Lin Chen explained.
"So, they are going to set the killing time 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 lead to death, so its effect should still make students who ingest it by mistake. become weaker and less resistant."
"Poisoning... Poisoning?" Wang Chao was so frightened that he almost exploded, "Come on, what should we do, do they know how to poison the drinking fountains? Are we going to check all the water sources, the school classrooms and the barrels in the library overnight? Water, and the mineral water that will be distributed at the event site?" But the workload is too great, "What if the problem lies with the source manufacturer of the drinking water, and it has already entered the market!"
The teenager's brain hole got bigger and bigger, and Lin Chen stopped him: "It won't be so difficult, let's analyze it, first, we haven't received any reports of colchicine poisoning yet, assuming there is a group of problematic Water source, then it has not entered the market yet, and supermarket distribution 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, "Secondly, If it is a poisoning incident aimed at student activities, it is very likely that the batch of water has been purchased and will only be distributed to students at the right time, so it will be relatively difficult to prevent similar free drinks; but the most difficult to control is the third point , if colchicine is in the hands of the members of the organization and they are poisoned by themselves, then the boiling water room in the school and the water dispenser in the classroom will become the target..."
"The third point is okay too, it's scary when 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. Moreover, the poisoning of public drinking water facilities cannot control the amount of drinking of the students. 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 excluded, it should be a targeted attack."
Lin Chen heard the words and looked again at the list of tomorrow's activities compiled by the dynasty. Although most school activities start after class at 5:30, the time limit of 6 pm can still help them exclude some daytime activities.
If the poisoning needs to be successful, a lot of drinking water is essential, so knowledge competitions, party joining ceremonies, college conferences, lectures can be temporarily excluded.
The rest is an indoor basketball game after school, as well as the activities of the A University Singer Competition and the T University Dance Festival...
It circled these three activities with a red pen, and then looked at Xing Conglian.
Tonight, Xing Conglian has been talking very little, especially since just now, he has been contemplating most of the time. Obviously, when it came to such a difficult decision, even Xing Conglian had some difficulty making up his mind.
In fact, there is still a period of time before the live broadcast tomorrow evening. If they respond quickly and take strong measures, then it is entirely possible to wipe out that organization in one go, and opportunities and dangers can be accompanied forever.
For example, the best way to deal with it is to deploy three specific locations, and both the deployment and the police force are well resolved.
However, if they choose this way of dealing, it means that they can't scare the snake in advance and must wait quietly for the other party to act.
Just waiting like this is putting public safety at great risk. Not only do they have to watch unknowing students drink highly toxic liquids and wait for them to become poisoned, but they must ignore those possible dangers to the public. Poisoning of water sources.
In this process, once there is any casualty, it is a heavy responsibility that they cannot bear.
Or, they can choose the easiest and easiest way to solve the problem: go straight out the door, smash the coffee bar across the street, then point the middle finger at the surveillance camera and write down all their speculations.
But the question is, what then...
Then, it is possible that the organization will order to stop the action, and the group members will continue to dormant. It is also possible that there is a second set of plans within the organization, so they will not be able to guess the location of the next dangerous event.
Even, the organization can let its members go to a place collectively and drink the highly toxic water in front of the teachers and students of the whole school.
The corpses are scattered all over the field, and the sky is mourning, so why not be 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 ask very, very seriously.
