"Zoom in on the robbers!"

Looking at a surveillance screen that had not yet been blocked, the commander-in-chief hurriedly gave an order to the personnel of the technical department.

Hear the words.

The technical staff quickly tapped their fingers on the keyboard.

quickly zoomed in on the figure of the robber in the surveillance footage.

The image quality of the surveillance screen is not too good, and there are naturally very few details that can be seen clearly after zooming in.

What's more, the robber is still wearing a hood, and even if the surveillance footage is clear, it is impossible to see his face.

But.

From the robber's body movements, you can still see his panic and eagerness.

Seeing such a situation, the commander-in-chief couldn't help frowning.

"Captain, the robbers seem to be ...... Only to realize that the surveillance camera is not blocked? ”

The team leader looked at the enlarged surveillance screen, and it was also a tentative opening.

Hear the words.

The captain did not speak.

He just stretched out his right hand and pounded his stubble chin.

His eyebrows were deeply locked, and his face was full of puzzled expressions.

It shouldn't be!

Judging from the information he obtained, a person like Zhao Ming should not make such a low-level mistake!

It's been almost an hour since the standoff, and he's really just now discovering the problem with the camera?

Could it be that these details were ignored because of nervousness?

But judging from his resume, he can't be such a psychological quality!

But the panic in the surveillance screen doesn't look like it's faked.

And he doesn't have to pretend like that!

And.

If the surveillance camera thing is his bureau, and he hasn't bitten the hook yet, he doesn't have to cover the surveillance camera, right?

Could it be that I really thought too much?

Is this surveillance camera really Zhao Ming's secret?

"Hiss......"

Thinking of this, the commander-in-chief couldn't help but take a cool breath.

He reached out and rubbed his temples, which were a little aching, and a look of unconsciousness annoyance appeared on his face.

If the surveillance camera is really Zhao Ming's mistake, then this is a great opportunity for the escort team to attack and raid.

And because of his misjudgment, he let such an opportunity slip away.

Now the robbers are aware of the problem with the surveillance cameras.

He will definitely choose to change his position after sealing the surveillance camera.

It is obviously impossible to use the bank situation that I learned through the surveillance screen to conduct a raid.

The commander-in-chief gritted his teeth and secretly clenched his fists, feeling extremely annoyed in his heart.

I actually missed the perfect opportunity to end the exercise.

This can be said to be a major mistake by himself, the top decision-maker of the escort team.

"Headquarters, now the robbers have blocked the surveillance cameras, and they have directly cut off the only way for us to know the inside of the bank."

"In such a situation, if you want to raid, I'm afraid it's not easy."

Just when the chief captain remained silent.

The captain of the special operations team of the escort team on the side frowned and reminded him.

Hearing this, the captain also nodded solemnly.

It is impossible to determine the location of the robbers, and if you launch a surprise attack, you will not be able to ensure that the robbers will be killed in the first place.

Naturally, this does not guarantee the safety of the hostages.

"Is it possible that we can start with the ventilation ducts?"

"Isn't there drones and electronic robots in the technical department?"

"Use them to carry cameras, enter through ventilation ducts, go to the location of the bank lobby, and find a way to find out where the robbers are."

"As long as the location of the robbers can be determined, the probability of a surprise attack is still very high!"

The other squad leader raised his eyebrows and opened his mouth to give his opinion.

Hearing this, everyone hurriedly looked at the captain of the technical department.

Apparently they felt that the proposal was feasible.

"No way!"

"The ventilation duct is generally a single-layer alloy plate, and the sound of drones and electronic robots is already loud when they move, and the sound will be amplified when they move in the ventilation duct."

"It's hard not to notice a situation like this, and if the robbers find out, it's very likely that they'll be enraged and endanger the safety of the hostages."

In the expectant eyes of the team leaders, the team leader of the technical department shook his head.

He explained with a solemn face.

Hearing this, everyone frowned.

"If it's a ventilation duct, I'd have an idea."

"We can prepare some sevoflurane and put it in through the ventilation duct and put everyone in the bank down."

"At that time, there is no need to even commit the risk of a surprise attack, just open the door and go in to control the robbers and end the exercise."

After all the squad leaders were slightly silent, the captain of the criminal investigation detachment, who had been following the captain before, spoke.

Hearing this, everyone's eyes were on him.

The leader of the special operations team raised his eyebrows and asked with a little curiosity.

"Sevoflurane...... What is it? ”

As he said this, the captain of the criminal investigation detachment looked back at him.

There was a look of surprise on his face.

The leader of the special operations team, who looked at each other and asked questions, was a little embarrassed for a while.

"Heptaflurane!"

"The most common inhalation anesthetic, colorless, transparent, and non-pungent odor."

"In the homicides we encountered, if the victim was anesthetized, most of them were with this inhalation anesthetic."

"Uneducated!"

The captain of the criminal investigation detachment raised his eyebrows and opened his mouth to popularize science.

In the end, I couldn't help but tease.

Hearing such ridicule, the leader of the special operations team also scratched his eyebrows slightly embarrassed.

"I don't have access to homicides, how can I know this thing......"

He smiled and excused himself, but he seemed a little unconfident when he spoke.

And when they heard him say this, except for the captain, the rest of them all smiled.

Time.

The oppressive atmosphere in the temporary command headquarters has eased somewhat.

Actually, there is nothing wrong with what he said.

He is not exposed to homicide cases, nor is he a medical student, so he has little access to anesthetics, and naturally he will not understand it.

Regarding the proposal to use sevoflurane, the team leaders obviously agreed.

After all.

This proposal is extremely risky and highly feasible.

Sounds perfect.

But.

After only two seconds, the captain, who had been silent, vetoed the proposal.

"Sevoflurane doesn't work."

"Sevoflurane needs a concentration of four percent to anesthetize, and overuse and too deep anesthesia can cause hair cramps all over the body."

"The area of the bank is more than 200 square meters, and there are no less than seven or eight vents of the ventilation pipes, and the pipes are quite complicated."

"In such a large space, it is impossible to accurately control the concentration of sevoflurane through ventilation ducts."

"Once the dose is excessive, the lives of the hostages and robbers are in danger at any time, and the insufficient amount cannot achieve the effect of anesthesia."

"Don't say it's an exercise, even if it's a real battle, it's impossible to use the method of sevoflurane."
