Xiao Yu, who opened the Falcon’s Eye, glanced at the home appliances and equipment.

The sweeping robot has no problems and is not touched by multiple people.

No problem with the humidifier, no problem with the dehumidifier, no problem with the air purifier…

Frowning, Xiao Yu came under the air conditioner.

Looking at the air conditioner that was plugged into the socket, sneered.

This is the most obvious human trace and suspicious point he found after watching the video.

Remember the surveillance video, the victim Song Ni turned off the air conditioner because it was too cold?

At that time, she obviously used a mop to unplug the air conditioner switch, right?

But later, when the police found the body, do you remember that the air conditioner was on?

30 degrees, the culprit that caused the corpse to rot rapidly!

Here comes the funny question.

Will artificial intelligence plug in the power supply?

If it weren’t for the artificial intelligence plugged in the air conditioner power plug.

Who will do it?

And this is a very obvious anomaly.

The artificial intelligence that loads your sister… Xiao Yu sneered and coldly stared at the air conditioner power plug.

The Falcon’s Eye can not only see far, but also can see details that ordinary people can’t see with the naked eye.

For example, fingerprints.

However, Xiao Yu was confused.

Because he not only did not see fingerprints on this plug, but also did not see the traces of artificial insertion on the traces of ‘accumulation of dust’.

How do you see it?

You think, like the air conditioner power plug, almost all year round will not be plugged in, easy to fall on the dust, dust.

Whether you touch it directly with your hand or with gloves, it will stick away some of the dust.

Without gloves, fingerprints will be left behind.

Wearing gloves will still leave traces.

But…… There were no fingerprints on this plug, and there were no traces of palm pinching.

There are only some traces of being touched by hard objects.

What hard object?

It should be the traces left by the victim, Song Ni, when she pulled the plug with a mop.

Could it be that no one but the victim had ever touched the plug?

Ghosts…… Xiao Yu’s forehead began to sweat.

At that time, in addition to the victim, artificial intelligence, there was also a ghost?

And this ghost, with the artificial intelligence crime, play together?

Xiao Yu, who had made up his brain a little, almost laughed at himself.

I’m really a genius, and it’s a pity not to write novels.

Brain holes are holes in the brains, but obviously this is impossible!

Ghost your sister… Xiao Yu waved his hand, and a team member brought a tool ladder.

He stepped on it, took a closer look at the plug, and carefully observed the marks on it.

Then he smiled, his expression became strange, and he scolded in his heart: Your special wife is also a talent!

What did Xiao Yu find again?

Sty…… To be precise, it should be a nail eye.

How did the nail eye become a needle eye?

Many of the power plugs are wrapped in thick soft rubber on the outside.

You take the nail and stick it in the thick soft rubber.

When the nail eye is pierced, it will become a needle eye due to the elasticity of the rubber when it is pulled out.

In less than half an hour, the team members found a stick and a nail.

Insert the nails upside down on the stick.

Xiao Yu unpluged the air conditioner plug and let it hunch over.

Then take the stick that has been nailed, insert it into the plug, and as the stick is lifted, place it on the power socket, with a force.

Click

Plugged in!

It’s another day of wits and courage with criminals, and I’m tired… Xiao Yu handed the stick to the stunned team members.

Wang Dong, who was a little buzzing in his brain, looked at the stick and then looked at the power socket, “Is this also OK?!” ”

“Why not?”

Xiao Yu sneered, “Criminals, what people do, they don’t do it!” ”

Wang Dong nodded.

Indeed, who would play like this in a normal person?

“If that’s right.”

Xiao Yu said in a cold voice: “This person should have plugged in the plug during the time when the victim turned off the power switch in the surveillance video, the room was in the dark, and the victim went to the bathroom to take a shower.” ”

As we all know, some monitors do not have the function of shooting at night, and the monitoring of the victim’s home in front of you is.

And this person is most likely the murderer, hiding in the victim’s house beforehand.

Appears when the power supply is pulled.

Why bother?

Because he knew the victim had a camera at home, he didn’t want to be caught by the camera.

Why not destroy the surveillance video inside the camera?

Because……

Xiao Yu looked at the seat where the camera was located, and on the entrance door, it was embedded in the wall.

If you want to take the camera out, you will definitely leave a lot of traces.

Therefore, he will deliberately plug in the power in the ‘dark’.

This is also why Xiao Yu would scold the murderer in his heart, “Zhen Te Niang is a talent.”

It also made him feel a strong smell of ‘late obsessive-compulsive disorder’.

Do you understand obsessive-compulsive disorder?

Sometimes this kind of crowd is like a perfectionist.

For example, if you see a red dot or digital prompt on a missed call on your phone, you must lose it.

If you see a prompt on the webmail, you should also get rid of it.

Some obsessive-compulsive disorders are even more pathological to the point where items in the home must be neatly arranged and cannot be moved by anything.

Even if you move, you must put it back in place.

It’s really a disease, and it’s still psychosis.

If it is serious, it is very likely to lead to depression, anxiety, and schizophrenia!

But obsessive-compulsive disorder and perfectionists are different.

The perfectionist’s brain thinks and spirit forces you to ‘perfect’.

People with obsessive-compulsive disorder think mentally, forcing you to ‘rationalize’.

Reasonable and perfect are two concepts.

For example, if your brain thinks it’s reasonable to do this, your body will be forced to do it.

If you don’t do it, you will be uncomfortable, not only anxious, but also difficult to sleep and eat.

Like the stick with the nail in it, use the stick to plug in the power supply.

Normal people think that you can’t be funny when you do this, is it funny?

But the suspects wouldn’t think so.

He thought it was reasonable and thought it wouldn’t leave a clue.

A nail eye, what can you find?

Then there’s the camera in front of you.

He thought that if he moved the camera, he would be discovered by the police.

Recognize that the air conditioner is plugged in in the dark, and I don’t want to leave a trace.

Why plug in air conditioning?

The case file shows twelve victims.

When the bodies of eleven victims were found, the air conditioners in the home were turned on at 30 degrees.

It’s also an obsessive-compulsive disorder, and the killer not only wants the body to decompose quickly.

It is necessary to turn on the air conditioner, and it is reasonable to think that the heat of the air conditioner accelerates the high rot of the corpse.

One more thing… Xiao Yu turned his head and looked at the smart speaker in the corner of the hall.

Every victim’s home has this kind of intelligent voice assistant.

The killer is also picking on the victims who have such intelligent assistants in the family.

The same is obsessive-compulsive disorder!
