Bro, you are a policeman, not a thug.

Inside a national security 'special service vehicle'.

Xiao Mu was watching the surveillance video.

Hotel surveillance.

Staring at a 'young man' in the surveillance video footage.

As well as all the travel scenes of the young man staying in the hotel for four days.

Xiao Mu clicked to pause and zoom in.

Then, he zoomed in on the young man’s hands, face, and skin.

Finally, he observed the young man's body shape.

A picture of the physical characteristics of a young man is created in his brain.

His eyes fell on the young man's face again.

A conclusion was reached.

"The face, eyes, hair color... are all fake."

Xiao Mu said calmly, "You all know, right?"

"Yeah." Zhao Ming nodded.

"It would be too hard to find him just based on his size."

Gao Shengli sighed, "People with similar body types are looking for a needle in a haystack."

This is why it is said that the other party can 'disappear out of thin air'.

Because their disguise is too good.

You can change your face, hair color, eye color, and skin tone.

Even the body shape can be changed.

A thin person pretends to be a fat person, a short person pretends to be a tall person.

Is it difficult?

When all these signs change, how do you find him?

The 'disguise technique' in martial arts novels is extremely weak compared to today's 'disguise technique'.

This is no longer a disguise, but like a different person!

"There's another thing he shouldn't be able to change, right?"

Xiao Mu looked at the young man in the surveillance video, "The walking posture is fixed, why can't I find him?"

Old people, middle-aged people, young people, and young people are all different in so many ways.

For example, ‘walking’.

Ordinary people will not notice that the walking and running postures from childhood to adulthood have actually been 'fixed'.

For example, some people walk with pigeon-toed legs, some walk with pigeon-toed legs, and some people walk straight.

The size of the steps, the swing of the arms, the hunchback, the chest, the head raise, the lower head...

These gestures have been ingrained over countless years and everyone walks differently.

No matter how much you change your face or body shape, your walking posture cannot change much.

So, why can't he be found?

What questions can Xiao Mu think of that national security investigators can’t think of?

Zhao Ming's face was solemn, "He can even disguise his walking posture, and all his habits and characteristics seem to have changed!"

This is why Guoan deduced that this person may be a top secret service agent.

Because only this kind of people have the ability to change their physical characteristics at will.

They can even transform from a man into a woman.

Or, you can change from a woman to a man.

Ordinary people think this kind of thing cannot be done.

But for top-level special agents, these are all basic skills!

On the contrary, national security investigators also know these things and can track them through these characteristics.

If not found, there is only one possibility.

Someone is more capable than you, and they use their strength and skills to crush you!

Now.

Not only one such person appeared, but more than twenty!

Xiao Mu asked, "Now that you have discovered it, have you applied for the deployment of special agents to assist?"

For example, whoever can defeat the police king must be the police king.

The other party may have top-level special agents, and those who can deal with them must also be special agents.

"Here he is, checked for two days."

Gao Shengli shook his head and said, "I can't help it."

no way?

This is not to say that Dragon Kingdom’s top special agents are not good.

But if they also used this method, the special services of other countries would not be able to detect it.

This kind of 'disguise' is basically unsolvable.

Unless you can lock down the opponent and then use some special equipment, you can break through his disguise.

Because this camouflage technique is targeted at criminal investigators, security personnel, and even surveillance tools.

This is also why spies are difficult to catch.

Traditional criminal investigation is ineffective... Xiao Mu rubbed his eyebrows.

These guys are playing with hard skills and high-end games!

"Didn't you even notice whether he left the hotel?"

Xiao Mu looked at the two old Guoan men.

Gao Shengli and Zhao Ming's faces turned red.

"Go back to the hotel and have a look."

Xiao Mu stood up, walked out of the special service car, and walked to the hotel.

Gao Shengli and Zhao Ming looked at each other, what else were they checking?

Xiao Mu: Cheating!

Why not open it in the first place?

Xiao Mu didn't want to deal with problems that could be solved by normal means.

Are you afraid that people all over the world won't know that you are a dick?

Do you still remember what the head of national security said when you were awarded honors by the Ministry of National Security?

[Don’t be too unscrupulous, curb your tactics, and don’t go too far. 】

The boss has warned!

…

Enter the hotel and return to the suspect's room.

Unparalleled Smell, open.

It's been six days and you can still smell human odor?

The answer is: yes.

Human body odor can remain in a fixed space for up to 60 days.

Moreover, human body odor has good qualitative stability for at least 20 days.

Especially the ‘bacterial’ smell on the human body.

It will take more than one to two weeks to break down.

For example, a person touches something.

The bacteria on your body have come to this thing and left a smell.

Humans can't smell it, but there are many animals with a keen sense of smell that can.

I hate being a police dog... Xiao Mu felt MMP in his heart.

moment.

Various smells entered his nasal cavity.

Xiao Mu frowned because he smelled countless human body odors.

It means that at least dozens of people have entered the guest room recently.

How to tell?

He walked over to the bed and sniffed the sheets.

Came to the bathroom again...

Finally settle on a light body odor.

Following the body odor, Xiao Mu came to the corridor.

His eyes fell on the carpet in the corridor and he sneered.

At that time, the suspect knocked down four national security officers and fled without even wearing shoes.

During this process, the soles of the feet will contact the ground, and body odor and bacteria will remain.

No matter how the air circulates, body odor can disappear, but bacterial odor will not.

Unless professionally disinfected.

Otherwise, as mentioned before, the bacterial odor will remain for at least 1-2 weeks.

key.

There are more than 21 times more bacteria on human feet than on other parts of the body.

The smell is stronger!

Xiao Mu moved slowly, came to the corridor, and walked to the hotel stairwell.

Go downstairs, jogging platform... stop.

Huh?

Xiao Mu was stunned for a moment.

Is the bacterial smell on the ground gone?

This discovery confused him.

For a moment, he looked towards the stairwell window.

Jump out of the window and escape?

wrong.

If the other party escaped through the window, national security investigators would definitely find out.

From the perspective of the Eye of Insight, Xiao Mu found no trace of anyone jumping out of the window to escape.

What the hell?

How did this person disappear?

After pondering for a while, Xiao Mu stood on the jogging platform and looked around with his eyes.

No trace, no hiding, no escape...

But for a living person, even the smell of bacteria on the soles of his feet is gone.

How?

No... Xiao Mu turned his head instantly.

Look at the window again and take a closer look.

There was indeed no sign of escape on the window, but there were traces of opening and closing the window.

Could it be that an aerial work vehicle appeared at that time and picked up the other party?

If so, it will definitely be discovered by the national security and there will be traces.

Xiao Mu reached out to open the window and inspected it.

Suddenly a sneer appeared on his face.

Hey, are you playing this with dad?
