After Yu Shaoyang was sent back to the detention center.

Xiao Yu stood in the villa bedroom.

He's ready to simulate a crime scene!

"Go into the bedroom, talk, argue, scold..."

Step by step to the edge of the bed, Xiao Yu's arms were in the air to compare some movements, and in his mouth, "After provoking anger... Homicide? "

His left arm first made a pull, and his right hand fell to the landline phone, picked it up, and used the telephone line to make a winding motion.

His eyes quickly scanned everything around him...

"Unreasonable!"

Xiao Yu stopped all the movements and frowned, "At that time, Wang Mei's consciousness was in a normal state, and the resistance should be very fierce... How do you control a woman who is struggling with resistance with one arm and wrap a phone line around the woman's neck... Isn't that just making a movie, is that reasonable? "

The first thing to be clear is that it is difficult to control a struggling person with one arm.

Not to mention one arm controlling, one arm using a telephone line to commit the crime.

The last thing is... Xiao Yu's gaze was on the bed, on the floor, and he didn't find any traces left after the fierce struggle.

Science?

If the whole killing process holds.

Wouldn't it be.

Wang Mei honestly let Shaoyang wrap the telephone line around her neck.

Strangled without any struggle, let alone any resistance?

Tell me a story?

Moving his gaze, Xiao Yu looked at the ceiling of the bedroom.

The interior decoration of ordinary people's homes will be 'hanging shed'.

The ceiling is mostly made of wood planks, which are processed in turn.

Xiao Yu's gaze was looking at a place on the ceiling.

There's a little hole there.

Its size is only one-third the thickness of a normal person's small finger.

It was one of the fifty-three camera locations that Xiao Yu had discovered.

Of course, the camera inside is gone, only the thread.

Where are these wires connected?

Xiao Yu was not clear.

Unless the villa as a whole is destroyed, the 'root cause' can be found.

But even if he didn't have to find it, Xiao Yu could roughly guess it.

The place where it is located must be very hidden.

Even if found, it should be empty.

"Can it be inferred that Yu Shaoyang's killing process ... Not established! "

Xiao Yu thought a little, "So, the third person appeared?" So what method did this person use to make Wang Mei lose his resistance and let Yu Shaoyang fall into a deep sleep? Drugs? Or some other means... Wait a minute! "

He walked inside the bedroom.

Windows, indoor toilets, and every corner...

Finally, Xiao Yu's gaze fell on a wall lamp on the wall.

What's so nice about wall lamps?

Because on this wall lamp, there is a hole in the thickness of a finger!

Then, Xiao Yu continued to search.

He found a total of five such holes in his bedroom.

They are wall lamps, chandeliers, wardrobes, a corner of the floor, and indoor toilets.

Having observed with the Falcon's Eye, these holes are not holes, but a kind of pipe!

"For what purpose?" Xiao Yu was puzzled.

The nose of the king butterfly... Open.

Although three years have passed, the villa has remained enclosed and there is no air circulation.

If there is some odor left in the pipe, there should still be residue, right?

Xiao Yu's nose approached the pipes and sniffed lightly.

Moment.

His body retreated in an instant, and his expression changed slightly.

What does that taste like?

Through the ability of the 'medical expert' given by the system, Xiao Yu's brain instantly got a definite answer.

Enflurane, sevoflurane, nitrous oxide...

What are these things?

Enflurane and sevoflurane: anesthetic gases!

Nitrous oxide: oxidants, chemical gas agents... Nitrous oxide!

For example, enflurane and sevoflurane, this gas is mostly used in surgery, giving surgical patients general anesthesia.

And nitrous oxide, this kind of thing can make people hallucinate and enter a certain state of excitement.

"That's the way it is!"

Xiao Yu was slightly stunned.

Recall some of the confessions made by the suspect Yu Shaoyang.

"Kill people... At that moment, I felt the blood in my whole body boiling, and there was an indescribable excitement! "

Blood boiling? Excited?

Normal people, after killing people, the blood boils, still very excited?

"It is certain that at that time Yu Shaoyang was anesthetized and unconscious. After waking up, Wang Mei was dead, her blood boiling and excited... Is it laughter? "

Xiao Yu's always flat expression flashed a hint of coldness, "Also produced some hyperactive hallucinations?" In this illusion, think that man is killed by himself? "

Reasoning holds!

Walk out of the bedroom and walk to the villa kitchen.

Xiao Yu continued to investigate for half an hour.

When he found five more small holes in the kitchen... After five pipes.

Breathing stopped instantly... A scene appeared in Xiao Yu's brain.

A person first used the pipe in the bedroom to release gas, leaving Yu Shaoyang and Wang Mei unconscious and killing people.

Then.

This person used gas to cause Shaoyang to fall unconscious again in the kitchen, took Wang Mei's body, dismembered it, put it into a suitcase, and put it back in front of Yu Shaoyang.

Finally, when Yu Shaoyang wanted to abandon the corpse.

Did this person secretly change the suitcase and use the dog's body to drop the body, as used the method used earlier?

Yu Shaoyang feels that the weight of the travel box is not right?

Yes, he couldn't feel it.

When the police found the dog's body, although only the bones were left in decay, it was also tested to be a large dog, a Caucasian Shepherd!

Adult dogs easily weigh more than fifty kilograms.

"Reasonable."

Xiao Yu murmured, "The corpse was replaced before it was buried by the abandoned corpse, right?" The reason for such a cumbersome operation, your purpose is to make Yu Shaoyang think that he killed people? "

You did it!

"What about the purpose?"

Xiao Yu couldn't figure it out again.

Suppose there is such a real murderer.

Why did he kill Wang Mei, blame Shaoyang, and then drop the body.

For what?

Suppose, if it were not for Yu Shaoyang's evil mentality, he would have trouble sleeping and eating all day long, and finally surrendered himself.

It seems that the police do not know that there is such a case, right?

Xiao Yu really couldn't figure it out, what good would it be to the real murderer to go through such a lot of trouble?

So, he was waiting for an answer.

The phone also happened to ring at this moment.

"Dude, the man has found it."

Wang Dong's voice rang in his mobile phone, "It is very coincidental that the Deng Hua you are looking for has returned to China, and is now on the passenger plane flying to Bincheng, and will arrive in an hour." "

Who is Deng Hua?

Real owners of the villa!
