Shenshan City, Yingtian Branch.

In a spacious room, a group of police officers sit around a projector, analyzing the case.

Next to the projection screen stood a middle-aged man with pale temples, who was Captain Chen in charge of the case.

The picture of the curtain flickered continuously, and finally froze in the Anfu community, Qiu Wei's home.

It has an eye-catching headline, and the light background sets off the big red letters, "The Mysterious Disappearance of a High School Student".

Then, the screen turns, and a photograph of the missing person appears on the screen.

"Qiu Wei, male, a senior in Baohe High School, mysteriously disappeared from his home two days ago. ”

Captain Chen was introducing the victim of this case, and his speech was very fast, and the police officer below took out a notebook and quickly wrote it down.

"We investigated the victim's friends and teachers, and learned that the victim had a gentle personality, normal behavior, family harmony, and no conflict with others, which can rule out running away from home and retaliation. ”

"Therefore, we have investigated the whereabouts of the victim on the day of his disappearance, Xiao Wang, report your investigation. ”

As he spoke, Captain Chen looked at a big man among the officers.

The big man named Xiao Wang stood up and said, "After our investigation, it can be determined that the victim went to the library on the day of his disappearance. ”

"Because the victim was a senior in high school, he went to the library to check the materials that day, and I have the library borrowing records and surveillance footage here. ”

Xiao Wang distributed the record and video to everyone, and then continued: "At half past three in the afternoon, the victim left the library and returned home in the No. 86 bus. ”

"At four o'clock in the afternoon, the victim returned to his home and did not come out until six o'clock, when his parents came home and found the victim and missing. ”

"Then I called up the surveillance of the community, and during the time the victim was at home, there was nothing unusual around. ”

"Now, it is almost certain that the victim has mysteriously disappeared from his home. ”

The officers frowned and whispered that the case was quite tricky.

Captain Chen nodded and said, "Lao Zhang, report on the on-site investigation." ”

"Yes!"

Lao Zhang stood up and said: "Judging from the situation at the scene, the time of the victim's disappearance was about between five and half past five, and the key is that we did not find any traces of struggle at the scene, indicating that the victim disappeared voluntarily or unknowingly, without any resistance and reaction." ”

"Moreover, we also found the victim's mobile phone at the scene, which had a call record on it, and then we investigated the victim's classmate Huang Yifan, and judged that the victim seemed to be frightened before the call. ”

A thread appeared in the minds of the people, stringing together all the clues.

Apparently, the victim had been threatened on the way back, and the person who threatened him knew the victim, so the victim was unguarded and disappeared from his home.

However, there are still many things that don't make sense.

At this time, Captain Chen said: "The victim's disappearance is extremely weird, but the mobile phone was left, so we brought the victim's mobile phone back and conducted a cracking analysis." ”

Then, a young man with a small head stood up, although he was a newcomer who had just graduated and had little experience, but he had extremely high technology in the field of electronic equipment.

Captain Chen looked at the inch-headed young man and said, "Zhou Heng, tell me what you have discovered." ”

"Yes, Team Chen!"

Zhou Heng was a little excited, this was his first time, and he had to perform well.

Then, Zhou Heng connected his laptop to the projector and began to demonstrate his findings.

"On the surface, the victim's mobile phone call history and the data in the mobile phone are normal, but after my research, I found that it is not. ”

Through the projector, Zhou Heng released a few pictures.

"You see, there are subtle traces here, and obviously the records and data have been altered, so I reversed the anti-missile, traced back to the source, and found something. ”

Everyone's attention was drawn as they looked at the curtain and waited for an answer.

Perhaps, this case was solved because of this.

Zhou Heng clicked the mouse, and in the next second, a picture appeared on the screen.

"This is, QR code?"

Everyone was puzzled, and on the curtain, there was a complete QR code.

Zhou Heng explained, "The operation of the mobile phone and the underlying data trajectory are extracted, as well as those lost records and data, all of which are combined to form this QR code." ”

What are you kidding, what does a QR code have to do with the case? Can it make people disappear out of thin air?

But some police officers looked at the QR code carefully, and their faces suddenly changed, as if they thought of something terrible.

"This is Number Five!"

An older police officer was horrified, his eyes full of uneasiness and trepidation.

Some of the officers heard it, their faces full of surprise, as if they had heard something.

But some of the new officers didn't know what was going on, and they even took out their phones and prepared to scan them to see what was going on.

"You can't sweep it!Xiao Wang, do you want to die!?"

Lao Zhang hurriedly stopped, "If this QR code is scanned, there will be a big problem." ”

It's just a QR code, as far as it?

Xiao Wang was puzzled, but he didn't continue to scan the code.

At this time, Captain Chen knocked on the table, and the conference room suddenly fell silent.

"This case is beyond our ability and I will hand it over to other departments. ”

Captain Chen glanced at the QR code on the screen again, and said, "This QR code must be destroyed, remember, some QR codes can't be scanned, don't blame me for not reminding you!"

Soon, this meeting was dissolved, and everyone was shocked, especially Xiao Wang, Zhou Heng and others.

Vaguely, they felt that they had been exposed to a terrible secret today.

When everyone was gone, Captain Chen sighed to himself, there was nothing he could do about this case.

When he came to his office, Captain Chen opened the secret compartment under the desk, which contained a top-secret file.

Turn the first page, and there is a case recorded on it, "Number One: Death Sickness".

Looking down, it is a QR code, and further down, it is the introduction of this case.

Anyone who scans the code will get sick, at first it was just a common cold, but as time went by, the condition became more and more serious, and finally evolved into a terrible terminal illness.

Terminal illnesses vary from AIDS to leukemia and cancer.

From health to serious illness and death, it only takes a month!

There are many terminally ill patients in the hospital, and people are dying all the time, and it is impossible to count which people died because of scanning the code!

Page 2, "Number Two: Desperate Maniacs".

This page also has a QR code.

This is a weird QR code, and the person who scans the code will be mentally devastated, struggling with various illusions and realities, and finally completely despair and become a madman.

Once mad, they will indiscriminately attack nearby people or animals until they die of exhaustion.

Page 3, "Number Three: Bloody Skull".

Seeing this, Captain Chen shuddered, this QR code is extremely terrifying, as long as it is scanned, there will be a tingling sensation in the mind, and it will continue to intensify over time, and any medicine and surgery will have no effect.

The only way to relieve the pain is to bang your head against the wall, and the skull is so bloody that the brains don't stop.

Therefore, the victim finally knocked himself to death, and the death was bloody and miserable, without exception.

Page 4......

Page 5.

Captain Chen's gaze stayed on the fifth page, "Five: Mysterious Disappearance".

The QR code on this page is exactly the same as the one on the previous screen.

It seems that Qiu Wei just scanned the QR code and then disappeared out of thin air. ”

Captain Chen rubbed his eyebrows, and sure enough, he still had to hand it over to the professionals, although he didn't want to deal with those people.

Looking at the remaining content of the file, which was more than fifty pages, Captain Chen suddenly felt a deep sense of powerlessness and crisis.

"The world is getting more and more dangerous. ”
