National Security Bureau 8: I, the King of Criminal Cases

The armed police guarding outside the building can also shoot them down!

But it's very strange.

Zhou Chen only smelled residual body odor on the 12th floor and couldn't "track" these body odors.

These body odors seemed to be cut off by "something" and could not be found at all.

This was the first time he encountered such a situation.

After a little contemplation, Zhou Chen understood.

In his previous life as a criminal policeman, he knew many colleagues, and also knew several colleagues in customs and security inspection.

I heard from those colleagues that some criminals, in order to smuggle contraband and smuggle drugs.

They often spray some odor-eliminating and odor-covering things and drugs on the camouflage surface.

For example, "deodorants" and "fragrances" for civil and industrial use.

This is done to prevent being smelled by police dogs and revealing their feet.

However, things that can eliminate human body odor are "professional" and very expensive.

Who can use this kind of thing?

Zhou Chen's face became cold.

Agent? Or spy?

But it must be one of them, because it is too professional!

There are three points for this inference.

1. When ordinary people are on the run, how many of them know how to cover up their body odor to prevent being chased by police dogs?

2. Even if you know, do you know what the medicine for covering up body odor is?

3. Who would carry something to cover up body odor all the time?

Zhou Chen looked at several subordinates, "Keep the blockade of the 12th floor."

"Yes!"

Three of the four special agents ran to the corridor to guard the corridor, stairwell, and entrance and exit respectively.

Only one person stayed with Zhou Chen.

"The body odor of eight people, six locals, and two aliens..."

Zhou Chen walked step by step on the 12th floor, scanning everything with his eyes, "Where can you hide?"

The 12th floor is an office area, but it is not an ordinary office area.

It is similar to a high-rise office.

The entire floor is full of offices of various sizes.

In the search just now, except for the seven terrorists, no one else was seen.

Zhou Chen knew that he was "deceived" by his eyes.

The so-called "seeing is believing" is not accurate at all.

Sometimes criminals have the ability to deceive the eyes of criminal investigators anytime and anywhere.

There are even some extremely powerful criminals who can not only deceive your eyes, but also use your eyes to mislead you.

The so-called seeing is believing does not exist in the field of criminal investigation!

All office doors were opened.

Zhou Chen, with his "eye of insight" turned on, searched carefully one by one.

To no avail!

Even my eye of insight can't see through?

Zhou Chen, who searched the 12th floor again, was a little confused.

Did I come to Gotham City, where the people are simple and honest?

Or is there something wrong with my sense of smell?

No... Zhou Chen shook his head and looked at the last location.

The public toilet on the 12th floor.

·· ········Please give me flowers·· ······

Although the 12th floor is a high-rise office area, not every office has a separate toilet.

The second time he came to the public toilet, Zhou Chen's expression became strange.

First of all, everything in the bathroom is clear at a glance, and there is no way to hide people.

Secondly, the bathroom has a faint smell of disinfectant, which is normal.

But what is abnormal is that the police dog will be smoked by this smell.

Animals with a keen sense of smell hate this kind of "irritating" smell.

Similarly, Zhou Chen's sense of smell has also failed.

His eyes and sights are inspecting the bathroom inch by inch.

Finally, he raised his head and looked at the ceiling with a strange expression on his face.

He had a bold guess.

In order to confirm the guess, Zhou Chen walked out of the bathroom and took a look at the ceiling of the corridor.

That's right, there should be something wrong with the bathroom.

Through the corridor, it can be found that the overall space height of the 12th floor is about 4 meters.

Because of the general floor decoration, there are few special decorations for the corridor ceiling.

Compare the height of the bathroom by visually measuring the height of the corridor.

2.5 meters?

A full 1.5 meters less in height!

"Decorating the ceiling, removing one-third of the height, are you stupid?"

Zhou Chen's cheeks showed a cold smile and walked back to the bathroom.

Through observation, it can be found that the material of the bathroom ceiling is PVC gusset plate.

This is a kind of material made of polyvinyl chloride resin, which is resistant to corrosion and aging.

Many commercial buildings use this kind of material to decorate the ceiling.

"Ladder." Zhou Chen said.

The special agent who had always been with him ran out.

A few minutes later, the special agent found a stepladder in the sundries on the 12th floor and moved it to the director.

Zhou Chen climbed up the stepladder, raised his hand, and gently pushed the PVC gusset plate on the ceiling.

Under normal circumstances, the weight of the PVC gusset plate is very light and can be lifted with a slight push.

But... Zhou Chen's face changed.

He felt a kind of "heaviness", as if he was not pushing the PVC gusset plate.

But a piece of steel plate!

...

PS: I overslept, please forgive me, I will work immediately! Loss.

Chapter 80 Come and play with me (2 more)

After discovering that the PVC gusset plate was not right, Zhou Chen took a look at the metal frame supporting the gusset plate.

His pupils contracted violently, and his heart trembled slightly.

Found it!

The ceiling is not made of PVC gusset plate, but a disguise. It is made of solid metal material.

As long as the steel frame has enough bearing capacity and there is still 1.5 meters of space.

There is a secret room above that can hide people anytime and anywhere!

Zhou Chen opened the Eye of Insight and carefully inspected the ceiling of the bathroom.

Finally, his eyes fell on a 1-meter square gusset near a corner.

Here... Zhou Chen lowered his head again and looked at the ground for a few times.

The ground was very clean, cleaner than other places in the bathroom.

"Gun!" Zhou Chen said coldly.

The special agent handed over the sniper rifle on his back.

He raised the sniper "997" sniper rifle in his hand and aimed at the gusset.

Zhou Chen pulled the trigger.

Boom!

A small hole was torn in the ceiling.

You should know that a normal PVC gusset will explode directly with one shot.

And the small hole in front of him was not only smoking, but also revealing the torn marks of the metal plate being pierced.

At the same time, you can also feel the thickness and defense of the metal plate.

The sniper bullet was so powerful that it didn't lift the metal plate, which means it was "locked".

Bang, bang, bang... Another four shots in a row.
