Criminal Psychology

Believe it or not, there are always some people who are especially good at making up stories. The stories they make up seem bizarre, but they can make a three-year-old believe in them all the time.

So starting from the Yongchuan University campus where two appalling mass suicides occurred, a mysterious rumor began to spread throughout the university city.

At first, the rumor only appeared on the public forum of Yongchuan University City, and the entire topic post was decisively deleted by the administrator within 3 minutes after it was published. No one can see the content of the entire post.

History is made by gossipers.

The time is 4:14 am on April 0th.

The dormitories of most schools have turned off the lights, but most of the students are still hiding under the covers with their mobile phones and surfing the Internet.

Therefore, when the students saw a bloody picture in Moments, it was not too late.

From the small picture, it looks like a wall, because there is almost no light, and the overall tone of the photo looks dark.

The student hiding under the quilt stretched out his finger and carefully opened the big picture.

The photo unfolded in a flash, and the bright red characters were reflected in the pupils of each student.

It was really just a wall, a wall painted with bright red paint.

Countless numbers and unknown characters cover the entire wall, which seems to be a collection of many calculation formulas, which looks extremely miserable.

where is this?

What happened?

Which lunatic has nothing to do with math problems on the wall?

Many students thought of this, and naturally turned off the picture, and continued to chat about school gossip in the small group, and discussed topics such as a certain department's grass getting married with a certain school, or a certain celebrity cheating again.

Even so, the unresolved questions will not disappear immediately.

So when the second photo appeared, it swept the students' circle of friends almost within a few minutes.

I don’t know who shouted in which group: Hurry up and go to the BBS of Yongchuan University City, something happened to Fenghuang Pedestrian Street, something happened! !

Soon, the entire message, including the address of the same forum, was quickly copied and pasted into different WeChat groups.

Even though the tone of the message was exaggerated, in fact, many students followed the link to the BBS of Forever University to take a look, and found that the situation seemed far less serious than the rumors said.

It seems to be a store in the underground pedestrian street of Phoenix Book City, and a bunch of mathematical formulas have been painted on the wall.

The glass door was smashed to pieces, a hammer was added to the log-colored floor, the glass shards were splashed, and the bright red characters became a bit permeable under the green fluorescent light of "Safe Exit". no big deal.

Therefore, the students who wanted to read gossip became disappointed again, and the replies below were also very boring.

[Damn, who, is it sick to paint red paint in someone else's shop? 】

[The probability of a mental patient in the Department of Mathematics is still very high. 】

[I thought it was Uniqlo, Uniqlo...]

[LZ die please, title party die. 】

[Don't always want to make big news! 】

Most people didn't bother to reply to the posts, and a small number of people who were too idle to fart also closed the page after replying to the posts.

Therefore, it was the administrator of the Yongchuan University City BBS who first discovered the abnormal situation.

When he clicked to delete the post, he found that the forum system reminded him that there was a problem with the administrator account, and the window kept reminding him that he did not have the permission for this operation. As a responsible forum administrator, he quickly called the school forum maintainer to report the problem .

However, when he was on the phone, a theme post with "marked red", "highlighted" and "refinement" floated on the homepage ostentatiously, and the content was also very ostentatious-please don't delete my post, if There is a next time, at your own risk.

The ID of the poster is the same as that of the owner of the photo building.

Occasionally, some students returned to the homepage of the forum, saw the pinned post, and were a little confused about the situation for a while. They clicked back into the "photo post" again, dragged the reply to the end, and found that someone had summed up the ins and outs of the whole thing in the first place.

Roughly as follows:

The poster with the ID SF9706 posted a bloody wall photo on the BBS of Yongchuan University City. After the post was published, it was quickly deleted by the administrator.This act of deleting posts seemed to have angered the host, so that person went to another floor, posted the same photo, and even posted a topic post to warn the administrator not to make any more petty moves.

Of course, it is impossible for the administrator to highlight and refine a provocative post. Only SF9706 can do this.

The "photo post" is still there, and the "warning post" is still on top. It seems that the administrator of the BBS in Yongchuan University City has either fallen asleep, or has been hacked and lost his authority?

[The SB administrator deleted my post 1 minute ago, it seems that someone really got rid of the authority? 】

A new reply soon appeared in the "photo post", and a screenshot of the time when the post was deleted was attached, proving the fact that the administrator's authority was lost.

If it's just an ordinary store being smashed and bloody books brushed, it can still be read as social news, but if even the school forum is hacked by the other party, things don't seem to be so simple.

So behind this incident, it is obvious that there is a real tech geek who can kill the school forum administrator in seconds.

The question arises, why did the technical geek hack the BBS of Yongchuan University City just to post two photos?

What was written on the wall, what did the person who wrote it want, and what did the person posting the photo want?

Everyone has different questions in their minds, and the replies from "Photo Posts" immediately boiled over.

[Damn it, who is the landlord trying to fight with? 】

【What did LZ do to that store? What is it for? 】

[It really seems to be the underground pedestrian street of Phoenix Book City. When I passed by after nine o'clock in the evening, the store was still in good condition? 】

[Did LZ hack the forum? 】

[Mathematics Emperor and Computer Emperor made a move? 】

[Who can understand what is written on that wall? 】

[Can LZ speak human language, low IQ can't afford it! 】

The number of replies increased at a speed visible to the naked eye, and the onlookers gradually realized that deciphering the content on the wall seemed to be the key to understanding the whole gossip.

For this reason, many mathematics students in the school have suffered bad luck. They were called up by those good-natured and gossiping classmates at one o'clock in the morning to study what the hell was written on the wall in the photo.

[I can't see it very clearly, but it seems to be explaining something? 】

[Reconsidering LS, is it really cracking the password? 】

[Still using the password? ? ?Is this espionage? 】

[It feels like there is going to be big news! 】

The lively places are not limited to the Yongchuan University City Forum.

The police force of the Yongchuan No. [-] Sub-bureau was also brightly lit all night.

"Dare to delete my post ah heh heh heh heh, how courageous..." In the office, Comrade Wang Chao opened another can of refreshing functional drink, and after taking a big gulp, he refreshed the page again to review the new reply Come.

Sure enough, even without them guiding public opinion, the conspiracy theories in the picture posts have become rampant. The brains of the students have expanded from those in the mathematics department to aliens invading the earth, and their thinking is still expanding.

As the night progressed, more and more people watched the excitement.

"You guys must hold on for a while longer, don't go to bed so early!" The young man in front of the screen who controls the whole system murmured to himself.

Before he finished speaking, he heard someone beside him asking, "How's the flow?"

"The number of people online at the same time is 973, but the growth rate has slowed down." Wang Chao replied, he thought for a while, and then said, "Ah Chen, can we make it in time?"

In fact, after listening to Lin Chen's full set of plans, Wang Chao, as the implementer, was not worried that the plan would not work. What he was worried about was that the effective time was too slow.

After all, they are now using the Yongchuan University City Forum as the basis to deliver the information they want to the 22 students in the entire University City. In this process, the most uncontrollable thing is the time required for information transmission.

"Large-scale information dissemination relies on accumulation and sudden explosion, which is what we often call the tipping point. As long as the tipping point is well controlled, there is still enough time." Lin Chen pinched the boy's worried face and said, "The number of online visitors To 1000, publish the next content."

The students frantically flocking to the BBS in Yongchuan University City probably never imagined that their every reaction was a process of being manipulated by humans.

The midnight blood book not only kept the gossipers up at night, but even alarmed the experts in various fields in this university city.

The most famous mathematics department account on the BBS of Yongchuan University City lit up, and the homepage of the forum was swiped by admirers in an instant.

[Fuck, is brother Xuan online? ? ? 】

[Brother Xuan, Brother Xuan, solve the problem! 】

[Brother Xuan, I love you, love you, love you. 】

【Brother Xuan is here to decode, what does that picture say? 】

There are more and more questions, but the account named CXUAN just went dark quickly after it was lit, and did not leave any reply.

Even so, the speculation of the onlookers did not stop there.

Rumor has it that CXUAN is the most talented student in the Department of Mathematics of Yongchuan University, Chen Xuan. The reason why Chen Xuan is famous is not because of the dozens of math competition trophies he has won, but because of his face.

Chen Xuan is very handsome, the kind of integrity and handsome that can be on the cover of a magazine.

Soon, Chen Xuan's fanatical fans began to share knowledge about Brother Xuan's glorious deeds to those who didn't know the truth.

Until the big hands of the art department went online, most girls had already focused their gossip on face licking.

It was almost 1:00 in the morning, but the number of people online was as stable as Mount Tai.

Of course, the masters of the art department are much better than the grass of the high-cold department. After all, she deliberately clicked on the "photo sticker" that has been covered with thousands of layers, and then replied [Signed... I seem to have seen it somewhere? 】

Just like digging a ditch to guide the water potential, the eyes of the onlookers all fell on a small area in the lower right corner of the wall.

There is a strange figure composed of three semicircles with small arrivals at the front and back, like unfinished wavy lines, but after careful observation, it can be found that compared with the scribbled writing formulas, the three semicircles seem to be drawn more seriously , since the master of the art department identified the wavy line as the signature, then the person who must leave the blood book seems to have left his signature arrogantly?

[I seem to have seen this signature somewhere? 】

[LZ give a password, SF? ? ? 】

[Could the upstairs stop being so secretive, and speak directly to the code. 】

[I don't think I need to sleep tonight...]

The issue of signature once again pushed the discussion in the chat thread to a climax. In the ever-increasing floors, various speculations emerged one after another. Soon, someone asked the most critical question.

[The right code upstairs, is he talking about Sanfen? 】

It's like a firewood lighting a dry wood, or a drop of water falling into a frying pan.

Everyone is guessing that in this post full of countless brain holes, a pattern and a simple keyword can instantly inspire many crazy associations, and even without deliberately guiding, the association Lin Chen wants can also be realized. It will come naturally.

【Damn, it can't be related to the three corpses dug up by Yongchuan University, I'm getting goosebumps! 】

Finally, someone asked.
