Bro, you are a policeman, not a thug.

The night deepened, and the summer streets were dotted with stars.

A police car stopped outside a villa community on the second ring road.

After getting off the police car, Xiao Mu did not rush to enter the community with Fang Shaoqiang, but observed the community.

The community is in a fully enclosed design, with a towering wall outside the area, surrounding the entire residential area.

The wall is three meters and a half high, and it is slightly more difficult to climb without using auxiliary tools, and there are surveillance cameras on the wall.

The residential area has four exits, divided into east, west, south and north.

One main gate and three side gates, all with guard booths, and guarded by security guards 24 hours a day.

There are three ways to enter and exit the community.

Access card, owner card, and security release.

Fang Shaoqiang looked strange and stared at the boy in front of him quietly.

He thought: There is indeed something!

Only some old criminal detectives know that sometimes clues and traces are not necessarily at the scene of the crime, but may be outside the scene.

Only some smart old criminal detectives will develop a habit.

Before arriving at the scene, check outside the scene first and conduct "reverse reasoning".

For example, in front of you.

Xiao Mu's purpose for observing the outside of the community first is only one.

No matter how the missing child disappeared, he first disappeared in the community and at home.

If it involves a series of situations such as trafficking and kidnapping, someone must have taken the child out of the community.

What method will this person use?

Excluding going up to the sky and into the ground, the other party can only leave through four doors and walls.

There is a surveillance on the wall, and if you leave from here, you will be discovered.

If it is not a wall, there can only be four doors, which will involve two problems.

1. The security guard has a problem.

2. The person who took the child away is most likely the owner or property staff of the community.

Because it is a closed community, outsiders can hardly enter.

A 5-year-old child is not small anymore, and it is impossible to be transported in anything.

It is very likely that vehicles and other means of transportation are involved.

And vehicles cannot avoid surveillance in the community.

If it is an outside car entering the community, there will be detailed records and registration.

Thinking of this, Xiao Mu was a little confused.

What he could think of, the criminal investigation personnel of the Fourth Brigade must have thought of.

They must have investigated, which means no clues or anomalies were found.

Since no anomalies were found, it can only mean.

The missing 5-year-old child is still in the community?

If I guessed correctly, the Fourth Brigade has searched the three buildings in the residential area.

If he is really hidden in the community, there is no way there is no trace.

Then there is only one possibility left.

Xiao Mu's expression is as if he has seen a ghost.

Go to the sky and the earth?

"Basement, sewage well, septic tank..."

Xiao Mu's expression is solemn, "Paraglider, flying wing, hot air balloon, drone, jet backpack..."

If you want to 'go to the sky and the earth', there are only these few ways.

Again.

What he could think of, how could the old criminal investigations of the Fourth Brigade who are more experienced than him not think of it?

"We have checked it all, it's not."

Fang Shaoqiang smiled bitterly, "That's why I asked you to come here and think of a way to help Uncle Fang."

This is Beijing, the capital.

It's not Gotham City with simple folk customs.

A living person disappeared strangely.

Don't you think it's scary?

"Let's go to the scene first."

Fang Shaoqiang led the way and walked towards the residential building where the child disappeared. "If you can't see anything, go back and rest early, don't delay the enrollment procedures."

I didn't expect anything when I asked Xiao Mu to come to help investigate the case.

It's a good thing if you can find it, and it's fate if you can't find it.

Looking at the back of his master, Xiao Mu was happy.

Who is he looking down on?

His temper came up instantly, and he followed his master.

He entered a residential building and came to the home of the person who called the police on the third floor.

Walking into the house, Xiao Mu smelled blood and saw bloodstains in the living room.

Thinking of the mother of the missing child committing suicide tonight, he sighed in his heart.

The figure of his mother appeared in his mind.

If he was in danger, his mother would probably go crazy!

Shaking his head, eliminating the distracting thoughts in his mind, Xiao Mu calmed his mind.

Then, he began to follow Fang Shaoqiang to investigate the scene.

The house is very big, with four bedrooms and two living rooms, more than 200 square meters.

Xiao Mu felt that he could not afford the house in front of him in his lifetime.

One and a half hours later.

After inspecting all the rooms, Xiao Mu's expression became gloomy.

It really was a ghost, there was indeed no abnormality or trace.

Something is wrong!

There is a law in the field of criminal investigation, the Locard exchange principle.

Also known as: Locard's material exchange law.

And this law was proposed by the famous investigator Edmond Locard in his "Criminal Investigation Course".

It has never been overturned so far!

What is it?

Any criminal process is actually a process of material exchange.

And the perpetrator can be regarded as a material entity. In the process of committing a crime, it is inevitable that he will come into contact and exchange with various material entities.

To put it bluntly.

No matter what crime it is, as long as it is committed, it will definitely leave direct or indirect traces at the scene.

The fact that you can't find clues and traces does not mean that it does not exist.

It can only show that your eyes, experience, and IQ are not enough.

What does this show?

It means that his IQ is higher than yours!

Xiao Mu wanted to swear to show his dissatisfaction.

It was like a foreigner who had just arrived in Beijing and wanted to taste some soy milk.

The main point was that he didn't believe in evil and started the second on-site investigation.

In a blink of an eye, it was midnight.

Standing in the living room, Xiao Mu wanted to say something sweet.

Still found nothing.

When I read novels, I thought it was cool to travel through time and reincarnate, and I could pretend in various ways.

As a result, when it happened to me, I was slapped by the little bitch of reality.

You force me to cheat, right?

Xiao Mu gritted his teeth and thought.

The wheel of fate that only he could see appeared in front of him out of thin air.

It was just past midnight.

It had been eight days since his last draw, and he had obtained 8 points of fate.

Seeing the pitiful 8 points of fate, the enthusiastic Xiao Mu calmed down.

Immediately afterwards, his heart almost cooled down.

With the nature of the wheel of fate and the experience of the last draw.

It was completely a farce to want to get a reward with only 8 points of fate.

No matter what, give it a try.

Xiao Mu gritted his teeth and started to draw.

Sure enough, there was no surprise.

After seven consecutive draws, the Wheel of Fortune also gave seven [Thank you for participating].

No, Brother Roulette, you play so dirty... Xiao Mu almost lost the ability to control his expression.

His heart was cold, and he was completely dead!

He sighed and became indifferent again.

He continued to draw with the last bit of destiny.

Xiao Mu didn't have any hope at all.

As a result...

The Wheel of Fortune suddenly paused, turned into a golden-red light, and gathered into four golden-red fonts.

[Eye of Insight]

Xiao Mu was stunned at first, and then his face was full of ecstasy.

This is very comfortable!
