Bro, you are a policeman, not a thug

"The surveillance camera was hacked and the source could not be traced. The network was connected using the Wi-Fi of the daily rental house."

Zhao Xiaotang reported with a sullen face, "The information registered in the daily rental house is from a certain province. It was obtained through illegal channels and cannot be traced... The enemy's anti-reconnaissance capabilities are extremely strong. They didn't leave any clues, not even a trace."

This is also expected. The person who could commit this crime cannot be an idiot!

At this time, everyone else was also looking at Xiao Mu who was smoking silently.

"Have you checked everyone else in the Jinling Criminal Police Brigade?"

Xiao Mu blew out a smoke ring.

"checked."

Dong Ruicheng smiled bitterly, "He didn't appear in certain places with the four victims, and he didn't do certain things... I tested it, and he didn't lie."

"Could it be that the other party only wants to kill four people?"

Xiao Mu tilted his head and looked out the window. "This is strange. What on earth did these four policemen do?"

What if there are no clues?

The same reasoning can be done!

In fact, the two most obvious clues have already appeared.

1. If the perpetrators are "accident makers" and they are a team, the person who can hire them should be a "big shot". Ordinary people cannot be exposed to this kind of profession.

2. The deaths of the four policemen may be related to some kind of cause and effect, otherwise how free would that big shot be to kill them?

And the key point is on "cause and effect".

What exactly did these four policemen do, or what did they do unintentionally, or perhaps they knew, saw, or heard... there are many possibilities.

Where should I start looking for clues next?

Xiao Mu, who was engaged in crazy reasoning, entered a certain state.

I began to review and ponder the four cases, and all the information began to be frantically pieced together and integrated in my brain.

Time is passing slowly.

Xiao Mu was never able to deduce any reliable clues.

"Go get something to eat first."

Zhao Xiaotang shouted, waking up Xiao Mu who was in the process of reasoning.

"it is good."

Xiao Mu came back to his senses, his eyes filled with fatigue.

Everyone walked out of the apartment together and took the elevator downstairs.

Just walked out of the unit door.

Sudden.

Xiao Mu's pupils shrank as he sensed danger.

The strangest thing is that I didn't sense any murderous intent or any source of danger.

What the hell?

Xiao Mu stopped and looked around.

Huh?

His gaze fixed on one place.

About ten meters away, there was a child about seven or eight years old.

A surprising scene appeared.

The child held a lighter in one hand and a pack of cigarettes in the other.

He wants to smoke?

No, the child just lit the cigarette.

Then he squatted down in front of a manhole cover.

He stretched out the hand holding the cigarette and slowly moved it toward the small hole in the manhole cover.

Xiao Mu's eyelids twitched, his brain started boiling, and he began to calculate frantically.

Counting footsteps, calculating time, calculating the direction everyone is walking...

If he didn't sense danger, they would go towards the child at this time.

And that child just happens to throw the lit cigarette into the sewage well.

And then……

The power of imitation - fleas.

Bang, there was a vibration under Xiao Mu's feet, and his figure disappeared from the spot.

When he appeared, he was already squatting in front of the child.

He held the cigarette between two fingers and stopped at the manhole cover.

No, the danger is not over yet!

Setsuna looked up.

Xiao Mu looked up at the sky and his face changed.

A window fell down along with its frame.

The place where it fell happened to be where he and the child were.

Xiao Mu grabbed the child, stood up and took a step back.

Or is it still wrong and dangerous?

Eye of Insight... Xiao Mu's eyes moved left and right and up and down frantically.

Then his eyes locked onto the falling window.

Double-glazed windows, one layer inside and one layer outside.

the strange thing is.

There was a wad of toilet paper wedged between the window panes.

toilet paper?

Xiao Mu's eyelids twitched, and he stepped back instantly and appeared in front of the unit door.

The moment he put the child down, he grabbed the unit door.

There was a loud bang.

Xiao Mu directly grabbed the unit door and used it as a shield.

The body moved again and appeared in front of the window that was about to crash to the ground.

Lift the unit door.

Bang.

The window frame hit the ground.

At the same time, Xiao Mu slammed the unit door in his hand against the window.

boom!

The ball of toilet paper exploded in the window like a grenade.

Xiao Mu's arms trembled in shock.

explode?

Xiao Mu sneered.

If, he didn't cover the unit door on it.

If there is an explosion, the glass will inevitably shatter.

Will the shattered glass fragments fly around like bullets?

By then, even if they were not hit by the window, they would have dodged it.

Will you also be hit by glass fragments and be seriously injured if not killed?

It’s a good imagination, don’t think like that next time... Xiao Mu sneered.

"Are you okay?"

Zhao Xiaotang and others rushed over, even drawing their service guns.

They were not blind, they all saw the explosion and were alertly looking around.

"No need to look, the person should have run away."

Xiao Mu looked at the sewage well in front of him and pointed, "There's something dangerous down there."

He had smelled not only methane and other gases (biogas) in the sewage well, but also gasoline and gunpowder!

Zhao Xiaotang quickly lifted the manhole cover, his face changed, and he also smelled gasoline.

He looked at the cigarette still burning on the ground, then at the sewage well, and finally at the child, his face turned ashen.

Not only him, but some of the police chiefs also opened the unit door and looked at the shattered windows below.

"Potassium chlorate and... red phosphorus?"

A police captain's face turned strange, and he muttered, "Throwing a cannon?!"

The reason I know about this thing is because I once came across a case of illegal firecrackers, where a batch of illegal firecrackers were seized.

Throwing firecrackers, also known as sand firecrackers, are small firecrackers that explode when thrown. Many people have played with them.

The ingredients of firecrackers generally include potassium chlorate and red phosphorus.

Potassium chlorate is a strong oxidizing agent and phosphorus is a strong reducing agent.

Moreover, both substances are extremely sensitive and will explode if impacted or squeezed.

This means that the ball of toilet paper stuck in the double-layer glass of the window is a large firecracker.

The purpose is to break the glass and injure people.

The sewage well in front of us has also been checked.

The methane was very heavy, and gasoline and gunpowder were also discovered.

If you throw an "open flame" like a cigarette butt down there, as long as any of them is ignited, there will be a horrific explosion.

Needless to say, what happened to those near the scene?

After realizing this, everyone's faces became even uglier.

Xiao Mu looked at the shivering child.

He had already guessed that someone had just been there.

Taking advantage of their time in the apartment, they set up some traps.

Or maybe a trap had been set long ago.

And the child in front of him is the key to triggering the trap and also the bait?

If that's the case...huh?

Xiao Mu looked up at another apartment building and saw a pair of eyes.

His face was covered with a layer of ice, and he almost laughed out of anger.

No, who gave you the courage?

How dare you not run away and eat melons nearby?
