C City, XX District, XX Street, Ronghua Community.

Inside a building.

Xiao Yu and Wang Dong were crouching at the scene of the case, looking at the dried blood on the ground...

"The cause of death of the first deceased was suffocated by the killer after being strangled by a tightrope."

"The cause of death of the second deceased was cut off the trachea and arteries..."

"The cause of death of the third deceased..."

Without continuing to listen to the C City police report the case, Xiao Yu stood up and went outside the first floor.

The whole building is an old building, two units of that kind.

But the two units were opened on the ground floor and merged into one unit entrance and exit.

The windows of every house outside the building are equipped with protective fences.

Not only can outsiders not enter, but also people inside cannot come out.

After entering from a single door there is only one staircase to the upper floor, there is no elevator.

The entrance to the second floor and to the merged unit were fitted with iron doors.

Just lock these two iron doors.

The next unit and the people upstairs could not get out of this building.

Roughly speaking.

This old building is like a small prison!

Three days ago, when the police arrived and saw the building, they were stunned.

Who would have imagined that there would be such a building in a city?

Scientific?

Unscientific is coming.

It's not just such a building.

It is also guarded by more than thirty silver sellers.

The three people who were killed were the members of the criminal gang who guarded these silver women.

The police followed the vine again.

Arrest of six members of the criminal gang involved in it.

After a police investigation, no traces of the murderer were found.

The murderer did not leave fingerprints, footprints, murder weapons... Even the motive for the killing could not be inferred.

The murder weapon can only be roughly inferred from the victim.

At the same time, the monitoring in the community did not find any suspicious people entering.

It was as if a ghost had entered the neighborhood and killed three victims.

Everyone knows that this is impossible.

There is such a person who has done it.

"Really an agent?"

Wang Dong frowned and walked over to Xiao Yu, who was standing outside the community.

"Who knows."

Sarcastically, Xiao Yu said, "Let's go and see the corpse first." "

City C, Forensic Department Anatomy Room.

After entering, you can see the three victims' corpses lying on three dissection beds.

Xiao Yu's eyes scanned the swearing wounds of the three corpses.

The pupils in the eyes dilated violently.

Two more quick contractions.

Xiao Yu found a feeling of 'familiarity'...

Walk to a corpse.

Lowering his head, Xiao Yu stared at the corpse's neck.

What does it feel like to be strangled?

In addition to the panic that the body experienced when strangled.

There are still several stages in this process, which can only be described as torturous.

In the first stage, the throat will tear.

When strangled, the arteries tear.

This tear makes it possible for blood to enter the artery wall.

In the second stage, the body is out of control.

People who are strangled are likely to completely lose control of their body's functions.

This can lead to a variety of strange reactions, including but not limited to bowel movements and urination.

In the third stage, the head seems to be about to explode.

In cases of asphyxia, the brain's oxygen supply is cut off.

This type of seizure is sometimes called a "brain attack" and is painful.

You think this is the end?

No, when it's all over, it doesn't have to end.

Why?

After being strangled, after death, there will be eyelid bleeding, cyanosis of lips, bruising of internal organs, fracture of hyoid bone, neck strangulation and other symptoms... But it cannot be generalized.

Why say this?

Because Xiao Yu found that the victim's death was very painful.

He wasn't simply strangled to death.

But in the process, being tortured by death.

He's being... Execution!

How did Xiao Yu find out?

How long does it take to strangle a person?

Strangling is not holding your breath...

The person's neck is violently tightened, and it may faint in about 10 seconds.

If it lasts for 20 seconds, not dying may also cause a lack of oxygen in the brain.

In 30 seconds, due to blood supply and lack of oxygen, it is possible to become an idiot without dying.

So people start from being strangled and blocked by lack of oxygen, trying to strangle a person, 30 seconds to 55 minutes is basically almost the same.

Even if the physical fitness is strong, in this period of time, people's consciousness will be completely lost.

Why 5 minutes?

Because even during the apnea period, the complete loss of consciousness is in a state of suspended animation, and within 1 to 2 minutes, there is also a possibility of emergency recovery.

But after this period of time, it completely enters the period of respiratory arrest.

Life will also be completely ended!

The victim in front of him, Xiao Yu, found a terrifying phenomenon from his body.

He should have been strangled alive for more than 10 minutes!

This can be seen from the black and purple face that he appeared after his death, as well as the neck stranglehold, and the dark red flow of the eyeballs.

There is a saying in forensic science about this phenomenon.

Two-stage suffocation and multi-stage suffocation!

What do you mean?

During the process of asphyxia, there is an insufficiency of blood supply and blood oxygen.

In this process, the victim restored blood and oxygen in a short period of time.

And then, in a state of suffocation...

Xiao Yu thought of an ancient punishment, hanging!

The process of hanging is to strangle a death row prisoner three times.

It's not just about letting a person die.

Also let this person experience the long process of death!

"What a cruel means!"

Withdrawing his gaze, Xiao Yu looked at the corpses of the other two victims.

One of them was slit throat.

But a plastic tube was inserted into the throat.

In this way, the victim will not die all at once, and can still breathe.

But with each breath, an artery bleeds from a torn artery until death.

The other one.

Xiao Yuyi twitched the corners of his mouth.

The other person's abdomen is completely shaved open, and the internal organs flow...

This is the most common cruel ancient punishment, open stomach and broken belly.

People who are entrailed and disemboweled will not die for a while and a half.

But it was very painful, and I could only watch myself die!

Three victims, two of whom were executed by ancient punishments.

The other one also died a terrible death.

Xiao Yu also found that all three of them were being attacked by similar sneak attacks, making them lose their resistance.

Only then was he brutally and brutally killed!
