Xiao Yu seemed to have eaten a dead mouse, it was hard to describe his mood at this time.

He now has two problems.

The first one: I want to greet the whole family of the person who controls the little bird. Is it convenient?

Second: How the hell did you do it?

First of all, it is not so difficult to control the bird to hold something without dropping it.

Secondly, control the bird to fly to a specific place and put things down in a specific position.

Again, control the bird to peck the glass, attract the attention of others, and cooperate with each other...

This unscientific feeling is like when you were in school, learning to learn and discovering that God closed the window of English for you, and by the way, closed the door of mathematics, and plugged the door of physics, even the dog hole of Chinese. I built it for you...

No, I can't resist everything alone... Xiao Yu turned his head and looked at Wang Dong.

In the end, it didn't look much better.

Wang Dong, who had been silent at the side all along, had an extremely ugly expression, full of shock.

Even he, the old Guoan, was very confused, feeling that the painting style of the world was a bit fantasy.

if not?

How do you manage to control five little birds and do these unreasonable things?

Swallowing his mouth, Wang Dong regained his senses and looked at Xiao Yu, "Can it be done?"

"Theoretically..."

Xiao Yu nodded, "It can be achieved!"

Just because you can't do it doesn't mean others can't.

I remember seeing a video of a crow once.

It makes a tool to dig out the small bugs in the tree hole.

At that time, Xiao Yu's eyeballs almost fell out.

Of course, this is all theoretically possible.

For example, in the case of the surveillance video, it was the first time Xiao Yu and Wang Dong saw each other!

"Look for someone." Xiao Yu walked out of the ward.

Wang Dong followed behind Xiao Yu with a serious expression.

Really looking for someone.

Wireless headsets are basically Bluetooth, and the suitable distance is mostly within ten meters.

It is certain that there is a person hiding in the hospital, controlling the bird, successfully using the Bluetooth headset, and committing a crime...

It is definitely impossible to catch people now, so how could they not run away?

It doesn't matter, as long as you have appeared, you will definitely leave traces.

Surveillance is everywhere in the hospital.

Under the comprehensive search of the national security, you want to hide your whereabouts?

I want to fart!

...

An hour and a half later.

"Head, I found it~~!"

A national security officer came to Wang Dong.

There is a monitoring room in the hospital, and there is a video.

There are four types of people who can enter and exit the ward area.

Medical care, patients, family members, sanitation workers.

Excluding these four types of people, suspicious persons are easy to find.

The suspect, a youth wearing a baseball cap!

Since he entered the hospital, he deliberately covered his face with a hat, wearing a pair of large glasses and a mask.

The body shape is easy to identify, about 1.8 meters tall, thin and frail, with a slight hunchback...

Xiao Yu held a photo of the suspect and stood in front of a window in the hospital corridor.

This is the third floor, and the fifth floor is the corridor outside Lu Jinyan's ward.

In winter, and it is a hospital, the windows are generally not opened.

But the window in front of me showed signs of opening...

Put down the photo, pick up the tablet, and click on a surveillance video.

In the video, the young man stood here and opened the window, took out a small box from his arms, released a few birds, and gestured to the birds.

Then, take out the Bluetooth headset.

No, not one earphone, but two.

Is the other just a headset?

No, it's a mini...camera!

The young man wears a camera with a bird around his neck...

Xiao Yu was stunned.

That's it, so you can see what's going on in the ward, right?

Then, the young man let a little bird hold the earphone, waved his hand, and five little birds flew away.

He waited with a mobile phone...

A flash of light, like thunder, suddenly appeared in Xiao Yu's mind.

He thought of a hypothetical reasoning of his own when he was in the K city hotel.

First of all, traces of drugs remained in the bodies of the past five deceased.

But no one approached them, and they couldn't find any way to 'feed' them medicine.

Xiao Yu finally understood.

Feeding does not necessarily require people, it can be birds.

Let the bird hold some kind of medicine, while the victim is not paying attention...

Hypnosis in Lenovo Live Studio...

All the clues are connected together.

The complete criminal process is in front of you!

"Then here comes the last question."

Xiao Yu muttered to himself, "You've worked so hard, what's the purpose of killing someone?"

There must be goals in everything you do, this is the eternal truth.

When people want to eat, they are hungry.

People want to drink because they are thirsty.

People want to sleep, they are sleepy...

People do many things every day, big and small, with purpose.

In addition to the so-called neuropathy, and some psychopaths.

Killing this kind of thing, kill it if you say it?

In order to kill people, it takes time and effort, racks your brains, and uses various methods. Do you believe that there is no purpose?

Xiao Yu can think of this.

How could Guoan not think of it?

Five dead... no, five victims now.

After the national security investigation, they were not familiar with each other in the past, or even knew each other, let alone caused any hatred, or offended, or hurt certain people.

Passion kills?

Xiao Yu couldn't figure it out.

"`. Target now!" Wang Dong put down the phone.

"So fast?" Xiao Yu's eyes lit up.

The two walked out of the hospital, got into a police car, and drove towards a certain shopping mall...

As long as it appears, there must be traces.

With traces, follow the clues.

The city's sky-eye monitoring has done a good job!

Skyeye monitoring is an indispensable monitoring tool in every city today (Zhao Lizhao).

Suitable for security monitoring and remote monitoring, forming a systematic management.

The system enables users to implement related management by realizing video monitoring and recording of video images.

For example, Litianyan monitors the whole city to search for a person.

This search method only needs to scan the portrait, and use the monitoring system to track the scan, scan the journey, scan the whole process...it can quickly lock on certain targets.

For example, the suspect wearing a peaked cap is.

After leaving the hospital, he was locked under the surveillance of Guoanli Tianyan.

At this time, he was entering a shopping mall.

Catch!
