Bro, you are a policeman, not a thug

Xiao Mu did not look at the burned young man who was screaming.

Instead, he squatted on the ground and looked at the glass marble.

Neither perception nor sight nor hearing could detect it.

How did it come about?

When it appeared, the young man's body suddenly caught fire.

How can this be done?

Xiao Mu's brain was analyzing, reasoning, and even calculating.

Suddenly, his body shook and his expression became strange.

A possibility came to mind.

Marbles, have they always been here?

It is only because of the angle, position, and human perspective that we overlook it.

Its function is not to make young people's bodies burn.

Just to attract his attention and make him bow his head?

The moment he lowered his head, the young man's body started to burn?

What did someone do to the young people in this process?

Xiao Mu raised his head and looked around.

His gaze instantly froze on the windowsill of the stairwell.

Another marble was found!

This marble is very special, transparent and attached to the glass.

Xiao Mu shifted his gaze and looked out the window with a puzzled expression.

wrong.

It’s the same problem just now.

How can glass marbles ignite open flames and set a young man's body on fire?

Xiao Mu suddenly narrowed his eyes because he was illuminated by the sunlight outside.

Sunlight?

Xiao Mu's eyes suddenly widened, he looked at the glass marbles again and reached out to pick them up.

It's clearly spherical, but when I lift it up in my palm, it looks like...

magnifier!

Gather light?

As we all know, a magnifying glass can focus light and increase temperature.

When the temperature reaches the ignition point of the combustible material, the material will burn.

It’s still not right… Xiao Mu’s pupils shrank.

At that moment, the young man's body was moving.

Even if this glass marble has a magnifying glass focusing function, it will not instantly ignite the young man's body.

It takes a process for the magnifying glass to focus and heat up, and the temperature is not high enough!

Xiao Mu moved his gaze to look at the young man's body, especially his clothes.

Recall the moment when the young man's body burned, emitting a fire-like explosion.

I wrinkled my nose and smelled a strange smell... garlic?

garlic?

Xiao Mu's face changed, and he looked as if he suddenly understood something.

Now I know why the young man's body is burning.

white phosphorus!

White phosphorus has a smell similar to garlic.

Its characteristic is that it ignites at about 40°C in moist air and slightly higher than 6-8°C in dry air.

There is white phosphorus on the young man’s clothes!

That glass marble has a focusing function, and it is easy to instantly focus the temperature over 40°C!

But precisely because he found the reason, Xiao Mu's expression became solemn.

How could someone have anticipated their presence in the stairwell and prepared two marbles there in advance?

One to attract his attention, and one to ignite the white phosphorus on the young man's body?

Xiao Mu's scalp felt a little numb.

I quickly went to the sixth floor, and then to the eighth floor, breathing a sigh of relief.

He found glass marbles on the landings on the sixth and eighth floors.

One is in a hidden position on the ground and the other is on the window.

There are two on each floor!

"You calculated that the young man would definitely use the stairwell, didn't you? You also calculated that someone would catch him in the stairwell?"

Xiao Mu murmured, "But that's not right. How are you going to determine the angle at which the marbles will be focused?"

and so……

Are you using some method to make the light shine on the marbles, and then use the marbles to shine on the young man?

Kill and silence!

That means you are nearby... Xiao Mu looked up and out the window.

After searching for two minutes, no unusual people were found.

"Something."

Xiao Mu smiled and said, "This is the only way to arouse my interest!"

……

hospital.

The youth's burns were treated simply.

Curled up on the hospital bed, his hands trembling, his eyes empty, as if he had lost all hope.

Xiao Mu was looking at him coldly.

It’s like looking at a… warning line!

"Warning line?"

Zhao Xiaotang's face turned grim. "Are you saying that the traps in the apartment complex were all deliberately set up by someone?"

"Yes."

Xiao Mu nodded and looked at the young man. "If we can find this residential complex, we'll fall into their trap and trigger the warning line. This young man will not only notify certain people, but also activate the trap."

"We can use that child to ignite the sewage well. If that doesn't work, we can also make the window fall down. These things were all arranged in advance by someone."

"It's just that he was too clever and added some things inside the sewage pit and the window, which was actually superfluous."

"But those people seemed to know him very well. They knew he might mess things up and that the police would find him, so they installed a trap in the elevator of that residential building."

"If this trap is activated, it means the young man has been completely exposed, and it will also be his death."

"Those people will also come to kill and silence the witnesses immediately and clean up all the tails."

"Or perhaps those people wanted to kill him anyway and made preparations in the stairwell in advance."

"There was a man waiting outside the apartment, intending to kill the young man, but he got away!"

If it were someone else, the young man would most likely be burned to death.

The other party's killing method was so powerful that even Xiao Mu was almost deceived.

But one thing is certain, the young man in front of him should know something.

People would kill him to silence him, or they would do so out of necessity.

Why do you say that?

Because this young man is a waste who is more likely to cause trouble than to accomplish anything.

It was clearly a high-level case of "accidental murder", but he turned it into a low-level "premeditated murder".

If this isn't trash, then what is?

Any teacher would give up on this kind of 'disciple', right?

What's the point of keeping this kind of garbage?

It makes me think that some people were forced to kill him to silence him in the end.

Have you guessed something?

"Your master is your relative, right?"

Xiao Mu looked at the young man coldly.

The young man's pupils dilated instantly, then quickly contracted and he lowered his head.

Police have identified the youth.

Wu Hao, 26 years old, from another province, came to Yongcheng two months ago.

The social relations of the suspect Wu Hao have almost been clarified.

Xiao Mu was holding his cell phone and looking at a document.

Liang Guanyu, male, 48 years old, from another province, was listed as a missing person 14 years ago.

He is related to Wu Hao and is also Wu Hao's uncle.

The reason why this person was found was that Wu Hao's other relatives had been monitored by public security personnel from other provinces.

No suspicious points were found through investigation.

The only suspicious person is Liang Guanyu, who disappeared 14 years ago.

The essential.

The file of Liang Guanyu before his disappearance was very clean.

And it’s very...awesome!

Not only is he a PhD, he is also an assistant professor. When he was young, he won a place in the International Mathematical Olympiad.

Engaged in mathematics work and possesses very strong mathematical analysis and calculation capabilities.

He can be said to be a genius in the eyes of ordinary people!

"Mathematics? Calculations? Accidents?"

Xiao Mu breathed a sigh of relief, "Sure enough, he is this kind of person!"

Only this kind of person can create so-called accidents.

And the killing methods that are difficult for ordinary people to understand!
