I went to the wrong table on a blind date and was kidnapped by my date.

"Report, all five private buildings have been searched. "

A special agent stood in front of Xiao Yu and Wang Dong, "Four of the buildings are rented apartments, and their internal monitoring is normal and there is no abnormality. The only private building is now under renovation and again there is no exception!"

No exceptions, inference error... Xiao Yu raised his eyebrows.

Needless to say, the ability of the special services of Gan'an.

Even they couldn't find anything abnormal, and they could only say that there was no abnormality in the five buildings in front of them.

But if not here, where would it be?

"Men lose their feet, horses lose their hooves. "

Wang Dong looked at Xiao Yu with a smile, "That prison under may not be here!"

Damn, the little brother can be counted as having a mistake in reasoning.

If we have always been exhausted, how can we ordinary people live?

Is this expression gloating, old brother... Xiao Yu tilted his head and looked at Wang Dong.

The psychology of micro-expressions to understand?

Just as he was about to rub Wang Dong.

Suddenly, Xiao Yu thought of something, "Did the white van find it?"

"Nope. "

One of the leading agents shook his head, "No suspected crime vehicle found." "

"That's not right. "

Xiao Yu frowned, "You have investigated and visited and confirmed that two months ago, white vans often came in and out of here?"

"Yes. "

The secret service nodded, sure, "However, none of the five buildings have the possibility of getting into the van. "

"You searched just now, there's a building being renovated, right?"

Xiao Yu raised his hand and pinched his eyebrows, "So, is the entrance door being renovated?"

"Ahhh..."

The secret service was stunned and nodded, "Yes, it is indeed being renovated." "

"Go, go and see. "

Lowering his hand, Xiao Yu scoffed, "It seems that someone wants to cover up the traces!"

Through the conversation between Xiao Yu and the secret service, Wang Dong heard something abnormal.

Why is it so coincidental to decorate the gate at this time?

So not renovated in front of the gate.

Can a van drive through this door?

Wait for everyone to come to the suspicious building.

Ten-storey building, standard small private business building design.

It looks like it's going to be converted into an apartment building.

The entrance door is indeed being renovated.

From the spacious gate of the past, it was built into a small unit door to enter the house.

Wang Dong called a decoration master and asked, "How big was the gate here in the past?" "

"Four meters wide, three meters high. "

The worker answered honestly, "The landlord asked for a new construction to be changed to an apartment-style three-meter-wide and two-and-a-half-meter-high unit entrance door. "

Xiao Yu glanced at Wang Dong.

Wang Dong's face turned cold.

Four meters wide, three meters high... Not to mention vans, ordinary large vehicles can enter.

With a gesture, the members of the second group surrounded the entire building.

All the workers who were being renovated were taken away for investigation.

The first floor used to resemble a business hall, and there was nothing to see.

From the second floor to the ninth floor, it is a business office area.

The tenth floor is the elevator machine room and warehouse.

Even if the search was re-searched, after two hours, nothing was found.

I really think too much myself... Xiao Yu's pupils contracted a few times.

The eye of the falcon, the nose of the king butterfly... After going down to the first floor.

Xiao Yu resumed the investigation.

This time he didn't take the elevator.

Instead, go up layer by layer within the safe passage.

Then another layer of search began...

When the nine floors were searched, the safe passage was ready to go to the tenth floor.

Suddenly, his footsteps stopped and his nose wrinkled a few times.

The smell of blood, the smell of human blood!

Why does this smell come from the stairwell... From the perspective of the Falcon Eye, Xiao Yu walked towards the tenth floor step by step.

This time, I found that something was wrong.

It is important to know that the step height of ordinary stairs is generally about 15 cm to 18 cm.

The steps in front of me are 22 centimeters high.

Not only that.

The number of stair steps to the jogging platform is 10.

From the jogging platform to the 10th floor, there are 13 steps.

Together, it's a 23-step staircase.

Any idea what this means?

Multiply by 23 steps for each step by 22 cm.

506 cm height?

That's more than five meters tall!

Why is the height of the ninth to tenth floors so high?

Xiao Yu, who looked puzzled, walked up to the tenth floor.

The bloody aura gradually became stronger.

The area on the tenth floor is the storeroom and elevator machine room of the building.

There are two elevators inside the building.

Because it is an old building, the computer room needs a relatively large area.

Then there is the warehouse, which has a lot of sundries.

All that's left is an inconspicuous room.

Xiao Yu smelled the increasingly thick bloody qi and moved forward step by step.

Until you stop at the end of the hallway, in front of a room door.

Push the door to enter.

Xiao Yu saw that there was a large double wooden bed placed inside, and there was nothing else.

The smell of blood came from this room.

After walking in, I smelled some strange smells, as if mixed with some air freshener.

Xiao Yu's sense of smell of 'King Butterfly' was also stimulated by the smell of this freshener.

He looked at the room suspiciously, ordinary can't be ordinary.

The area is not very large, about forty square meters.

It can't be some kind of 'underground prison'.

Is that 'underground prison' really not in this building?

Xiao Yu's eyes suddenly flashed with an indescribable strangeness.

No, there is a problem with the spacing between the ninth and tenth floors.

Climb a flight of stairs five meters high?

Science?

......

An hour later.

A secret service officer brought a building drawing and handed it to Xiao Yu.

After looking at it carefully, Xiao Yu curled the corners of his mouth.

Not laughing, but mocking.

There is indeed a problem with the ninth and tenth floors!

Because it is a private building.

At the beginning, the building was set to a height of 4 meters per floor, and the thickness of the floor reinforcement was about 50 cm.

4 times 2 is 8 meters, plus the floor slab 50 cm.

The height of the two floors together is close to 8.5 meters.

But......

The internal height of the ninth and tenth floors in front of you is only 2.5 meters?

The upper and lower floors together are only 5 meters high?

Even with the floor, it's only 5.5 meters?

Here's the problem.

According to the calculations on the architectural drawings.

The two floors together are obviously 8.5 meters, but now it is only 5.5 meters?

It turned out to be 3 meters in height and disappeared ?!
