Risking their lives to solve the case, criminals all over the network are going crazy

Liu Yu's brain thought quickly, it is very likely that the warehouse is not the first scene, the real scene is the mango tree.

Because the interior space is limited to see through the door keyhole, the first scene Chen Ying saw in the warehouse that night was actually the mango tree outside the house.

At that time, it was the murderer who hung the tattooed man's body on a mango tree.

And the sound in the warehouse is also most likely made by some special means.

It leads to the misconception that the warehouse is haunted.

Suddenly, Liu Yu remembered the island's specialty - rats!

Will the murderer use rats to make special sounds in the warehouse, such as screaming, biting, squeaking strange sounds.

But this brain hole is too big, and using animals is not a simple matter.

At present, the animals used by humans are the most dogs and birds, and as for the mice, they are all living in cartoons, called Jerry and Tom.

To the right of the warehouse is a guest room, and on the left is Dean Sun's room.

Here's the problem.

Directly outside Dean Sun's room is the mango tree, the mango tree where the tattooed man hanged.

So how did Chen Ying see the situation outside the window through the keyhole?

Could it be that Chen Ying has perspective?

Liu Yu paced back and forth in the room, and finally did not understand the reason.

Could it be that the murderer, like in a fantasy novel, can project one time and space to the other?

Coolness, from the tail vertebrae to the top of the head.

Straight to the heavenly spirit cover.

I think of a classic line in a horror movie, ghosts are scary, scary to death, people are scary, scary to death.

And at this moment, Liu Yu's brain supplement brought the greatest fear.

Instead, reason from the convex lens in the keyhole.

What is the function of a convex lens?

Visually close distant objects and zoom in on their features.

How to zoom in on distant objects and turn them.

Submarine!

Yes, that's right, the submarine feeds back the situation on the sea surface to the crew at the bottom of the sea through the principle of reflection.

Equally!

The mango tree outside Dean Sun's window can also be presented on the keyhole in this way.

Liu Yu's eyes searched the house again, but he did not see any devices.

The reasoning has reached a dead end.

It seems that reasoning in this direction will not work.

Looking at Liu Yu, who was silent and seemed to be thinking.

Liang Xin asked in a low voice, "Team Liu, what did you find?"

Liu Yu wandered out of the reasoning and replied: "Look at the keyhole, there is a convex lens device inside, which can present the image inside the house to the observer outside.

Liang Xin half-squatted and observed for a while.

Suddenly: "Are you saying that the murderer used a magnifying glass to show the process of hanging the tattooed man under the mango tree through the keyhole?"

Liu Yu nodded heavily: "That's right. Liang

Xin's head turned extremely fast, and he immediately understood what Liu Yu meant.

Liang Xin's face showed a stunned expression: "How did you do it?" "

Hey, brother, I can't figure this out, I still want to ask you: "The reflection of light!"

Liang Xin's face was full of puzzlement, one second genius, the next second.....: "Through the reflection effect, the scene outside the house is projected to the keyhole!"

Liang Xin carefully observed the interior of the room and did not find any relevant reflective devices.

How the murderer did it.

Liang Xin looked at Liu Yu: "...

Liu Yu: "...

I don't understand either!

Got it, bumped into a piece and went.

Or Dean Sun, will you give an explanation?

The two turned their heads at the same time and looked at the tall Dean Sun, who shrugged his shoulders and spread his hands.

To have one’s hands tied.

Suddenly, a voice came from behind him: "Have you ever had a stomachache?"

The three turned their heads at the same time and looked at Li Sansi who walked in from outside the door.

Li San thought that there was no movement for so long, so he went upstairs alone to see what was going on.

Just heard the extreme conversation between Liang Xin and Liu Yu.

"It hurts!"

"It hurts!"

Who hasn't been a police officer ever hurt? Stomach problems are standard.

Stay up late on duty all year round, nervous tension, anxiety, the most prone to problems is gastrointestinal disease.

Therefore, Liu Yu and Liang Xin answered this question in unison.

I saw Li Sansi walk in from outside the door.

So, is stomach pain related to this case?

A question popped up in Liang Xin's mind.

However, after Li Sansi asked a question, Liu Yu's eyes suddenly lit up.

Staring at the position of the keyhole behind the door, Liu Yu's eyes flashed with fiery light.

"Got it!"

Liu Yu quickly closed the wooden door and looked at the keyhole position from behind the wooden door, sure enough.... There is a new mark in the keyhole of the wooden door.

The holes are stretched open, and the surrounding areas are clearly rubbed with traces.

That is to say, there is a device similar to the periscope in the submarine, connected to the keyhole position at the door, and the other end is facing the mango tree position outside Dean Sun's window.

So!

When Chen Ying looked at the keyhole that night, she could directly see someone hanging the tattooed man.

It is because of this reflex device.

And Li Sansi asked about stomach problems for a reason.

Many people with stomach problems will do gastroscopy, and the gastroscopic equipment used in gastroscopy is a soft thread with the thickness of a black little finger.

The principle of gastroscopy is the total reflection of light.

In summary, the murderer is most likely to use a gastroscope tube, one end is connected to the keyhole position of the warehouse, and the other end is connected to the crime scene.

Through the principle of gastroscopy management of total reflection, the scene situation is presented in the keyhole, which plays an ultimate haunted event.

But the so-called black gastroscope tube was not seen at the scene.

The murderer must have quickly taken away the pipe when Liu Yu and the others entered the room that day.

How did he do it?

Liu Yuke remembers that that night, Chen Ying was hung from the scene of the discovery of the crime, screamed to wake everyone up, and then the group arrived at the warehouse for no more than five minutes.

It takes time for the murderer to recover the gastroscopy tube.

Between electric flints!

A picture exploded in Liu Yu's mind.

Rayong!

He remembers that night, Rayong was the last to open the door of the room, ask what had happened, and then specifically remind him that the haunting was because he had played an orphanage game.

From the time of the crime to Rayong appeared, the time was almost five minutes, which was enough.

Moreover, the next room to Rayong is Dean Sun's room.

Not far from the warehouse, it is theoretically possible to recycle the gastroscopic tube.

"Go!" Liu Yu thought about this and said.

But Liang Xin and the others' brain speed could not keep up with Liu Yu, and they wondered why Liu Yu suddenly left the warehouse.

But the body told him very honestly that it was probably right to follow Team Liu.

Liu Yu arrived at Luo Yong's room very quickly.

Rummage through the room.

Liang Xin was a little puzzled, what was going on with Brother Yu, what was he looking for.

Dean Sun also looked at the young police officer, thinking that he must be looking for something important.

Liu Yu stopped in front of Luo Yong's bed, lay down, pouted his butt, and looked at the bottom of the bed.

A circle of black tubes appeared in Liu Yu's field of vision, and Liu Yu reached for the circle of black pipes.

One grab and one pull.

Liu Yu lifted out the black pipe that circled the city and appeared in front of everyone.

"This is it!"

"Crime aids."
