Late, 7 o'clock.

The entire third brigade worked overtime without even eating.

Conduct a blanket search of the business building.

On the rooftop.

"There are shops on the 1st floor with a reception, leisure area, monitoring room, and property office. The 2nd to 4th floors are a fitness club. The 5th to 10th floors are offices. The 11th to 15th floors are the office address of a company. The 16th to 18th floors are A certain company’s conference room, demonstration hall, and negotiation room are located on the 19th to 23rd floors of a hotel with a view and guest rooms, the 24th floor is the building owner’s office, and the 25th floor is the elevator machine room, cleaning warehouse, utility room, and security lounge.”

"There are three elevators in the entire business building, including two civil elevators and one freight elevator."

"Monitoring equipment has been set up in the three elevators and in the corridors of each floor... However, after our investigation of the surveillance video footage, we did not find any suspicious persons or the possibility of entering the building with flying tools."

A criminal police officer reported on the situation inside the building, "We also checked the only entrance to the rooftop and found no trace of anyone logging onto the rooftop. However, there were suspicious footprints on the rooftop, as well as traces of flying tools."

Damn it... Everyone looked at each other in confusion.

If no suspicious persons or suspects are found, forget it.

Even the only entrance to the rooftop showed no signs of entry.

So how did the other party get on the rooftop and fly up?

The entire business building has 25 floors and is nearly one hundred meters high.

How to fly?

What the hell is this if it’s not hell!

Just because they can't figure it out doesn't mean others can't figure it out either.

In an instant, these old detectives all looked at Xiao Yu, who was silent at the side.

It can be said that from beginning to end, all the clues in this case were discovered by this school police officer.

It doesn’t matter whether you admit it or not.

Xiao Yu's brain is indeed better than theirs.

This group of veteran detectives were blushing and looking forward to it at the same time.

I want to see if this school policeman can come up with other ideas.

"Xiao Yu, it's up to you."

The instructor He Yong looked at him with a smile.

They are using me as a tool... Xiao Yu almost laughed, "There is no way he can fly to the rooftop of the building."

Um?

Everyone was stunned and thought: Isn’t this nonsense?

But the next second, everyone's heart beat suddenly.

wrong!

They are all veteran detectives, so their reasoning skills go without saying.

Xiao Yu's words were obviously asking them, how did a normal person get to the rooftop without leaving any traces?

That's not even the point.

The point is that in the process of going up to the rooftop, he also has to carry a body.

No kidding.

Even if you find the most powerful climbing master in the world and ask him to carry a weight of 65 kilograms, he still won't be able to climb the rooftop of a 100-meter-high building!

What is sixty-five kilograms of weight?

The body weight of the victim Zhao Dechao!

"So, he can only go up to the rooftop from inside the building?"

Xiao Yu's master Wu Qiang, with twinkling eyes, told what everyone was thinking.

"Yes and no!"

Xiao Yu looked towards the edge of the rooftop, "Inspect the traces on the edge of the rooftop and see if you can find any rope fibers!"

His words were like a thunderbolt that struck the heads of everyone present.

Understood.

Xiao Yu's words had told them clearly.

Someone should have gone to the rooftop in advance and then used ropes to pull the body up to the rooftop.

If ropes are used, there will definitely be rope friction marks on the edge of the rooftop.

You can all think of this, what kind of IQ must it be... The eyes of everyone looking at Xiao Yu changed again.

It was like looking at an unknown creature, more like looking at a monster.

More than a dozen criminal police officers began to investigate the corners of the rooftop of the building, focusing on the edges where ropes could be pulled.

"There's a discovery!"

It didn’t take long, a criminal police officer exclaimed.

When everyone came closer, their eyes fell on a rooftop metal guardrail.

The guardrail is made of welded white steel pipes with a smooth surface.

After years of exposure to wind and rain, it has left behind traces of corrosion, weathering, oxidation, and other rust.

Because there is rust on it, if there is a rope pull, it will inevitably leave extremely obvious marks.

For example, wear and tear, or rope fibers scratched and left by rust on the steel pipe.

"The suspect should be a male and in very good physical condition. The floor where the body is transported should not be too high."

A criminal police officer gives his opinion based on experience.

Everyone nodded.

This is easy to reason about.

Most women don't have that much strength.

Due to poor physical fitness, he was unable to pull a 65-kilogram corpse onto the rooftop.

The floor where the other party transports corpses will not be high because even those with the best physical abilities have limited strength.

You ask a person to stand at a height of 100 meters and try to pull up a weight of more than 100 kilograms below?

Even calling the most powerful strongman in the world can't do it.

So this floor must be very close to the rooftop.

No more than ten floors at most.

This is already the limit that humans can achieve.

Soon, the criminal police locked the suspicious floor.

21st floor, view hotel, one room!

When I walked into this room and came to the floor-to-ceiling windows, I found drag marks on the windows and exterior glass.

This kind of scratch is the dust mark on the glass left after being rubbed by dragging objects.

But after investigation, strange things appeared again.

This room has no record of stays within 12 days.

No check-in means no one has entered.

After checking this, all the criminal policemen, including Xiao Yu, got big heads.

What kind of murderer is this that has such anti-reconnaissance capabilities?

Just the process of dumping the body made everyone spin in circles.

It can be described as terrifying!

"Re-investigate guest room area surveillance and housekeeping staff."

Zhou Xiangguo issued an order in a stern voice, "Inform the forensic doctor to come over."

As long as it is confirmed that this room is the scene of corpse transportation, traces will inevitably be left.

After the two criminal police officers left, the others found that Xiao Yu, who was standing aside, was still calm and composed.

"What did you find?" He Yong looked directly at Xiao Yu and asked.

"Not yet, but it's weird."

Xiao Yu frowned and shook his head, "If the other party is so smart, why did he leave such obvious clues?"

Whether in his previous life or in this life, he hates criminals with brains.

It is not difficult to find that the perpetrator of the case in front of him has a very high IQ and a sophisticated layout.

However, the easiest thing for smart people to do is to be smart but misunderstood.

Because this kind of people often make it more difficult for themselves when calculating others.

They will use their thinking to make clever arrangements and use means to show their IQ.

It is obviously a simple thing, but they will try their best to complicate it.

And in this process or link, it is extremely easy for some mistakes to occur.

Suddenly, Xiao Yu suddenly raised his head, his expression ugly.

"No, someone deliberately lured us here!"
