In the warehouse, there was silence.

Empty, you can hear your own breathing.

In the air, there seemed to be a heavy smell of dust.

As soon as they entered, several young police officers took a deep breath and then covered their mouths and noses to prevent themselves from coughing.

"Attention, cover your mouth and nose, it looks like there's flour here."

Gu Ling suddenly thought of something, his face changed, and he turned his head sharply and said:

"Attention, turn off the safe, don't fire, beware of dust explosions!"

Dust explosion refers to the combustible dust within the explosion limit range, encountering a heat source (open flame or high temperature), the flame instantly spreads in the entire mixed dust space, the chemical reaction speed is extremely fast, and a large amount of heat is released at the same time, forming a very high temperature and great pressure, and the energy of the system is converted into mechanical energy and light and heat radiation, which has a strong destructive force.

Dust explosions are mostly in production and processing sites accompanied by aluminum powder, zinc powder, aluminum processing and grinding powder, various plastic powders, intermediates of organic synthetic drugs, wheat flour, sugar, sawdust, dyes, bakelite ash, milk powder, tea powder, tobacco powder, coal dust, plant fiber dust, etc.

In the flour mill, dust is suspended in the air, and the most taboo thing is an open flame.

Because after the dust reaches a certain level, it will cause a large explosion when it encounters a little open flame.

Therefore, the employees of the flour mill used to wear protective clothing, and dragged grounded iron products under the clothing, so as to channel the static electricity caused by friction into the ground and prevent the discharge phenomenon from producing open flames, so as to blow up the flour mill to the sky.

"Go back, go back, open the gates, guard the surroundings, call the blower, let's ventilate it!"

There are generally three dust explosion conditions:

(1) Combustible dust is suspended in the air at an appropriate concentration, forming what is often referred to as a dust cloud;

(2) There is sufficient air and oxidant;

(3) There is an ignition source or strong vibration and friction.

The use of effective ventilation and dust removal measures, smoking and open flame work are strictly prohibited, which is the way to avoid dust explosion.

Generally speaking, when the concentration is reduced to a certain level, there is no longer a risk of explosion.

Dozens of black shadows, lightly, how to get in and out.

Get off the wrong foot!

Under the darkness of the night, the public security officers who retreated outside were overshadowed in their hearts for no reason.

The valley drop is even more obvious, and a heavy pressure is felt.

His palms were sweaty, and he tried to take a deep breath to calm his excitement.

Years of lurking in the dark gave him a keen instinct that made him feel a little bad.

The warehouse with the door open in front of it, blown by four high-power fans, stood quietly in the deep twilight, like a pair of open mouths, ready to pounce at any moment·······

When he was terrified, out of the corner of his eye, he suddenly caught a glimpse of a white shadow and swept by.

"Who!"

Draw your gun and aim!

At this point, there's nothing more to sneak into······

With such a big move, to talk about the so-called infiltration is nothing but self-deception.

So he simply shouted out neatly.

"Section chief, where is someone?"

Seeing that he suddenly pulled out his gun and aimed, the public security officers also subconsciously pulled out their guns and scattered and lay down.

Nothing was found.

"Didn't you all see that? There was a white shadow just now, it seemed to be a person! ”

Zero was convinced that he was not mistaken.

His eyesight is specially trained, and even on a moonless night like this, he can see farther than ordinary people.

Especially dynamic vision, so close, only a distance of more than ten meters, it is impossible for him to see such a conspicuous white shadow.

However, all the police, in unison, said that they did not see it.

The feeling of uneasiness in the heart of the valley is accumulating more and more······· He regretted the operation a little.

Obviously, he was a rising star of public security before he became an undercover agent, and after he came back, because of his years of undercover work, he was promoted to the chief of the second section of the second department of the public security search, and there were only a few people who stood on him in the public security system.

Even if you can get some credit this time, you can't be promoted again····· This small credit did not mean anything to his promotion to minister.

Undercover is a very dangerous job, but once it is successful, the credit is not small, which is enough to erase the qualifications of others for more than ten years, and it is the only way to quickly promote the position····· The premise is to survive and complete the mission to destroy the undercover organization.

The Japanese public security department is divided into the first department of search, the second department of search, and the department of general affairs.

Below the second department of the search, there are the first section, the second section, and the third section.

The position of section chief, even if you have a family background and talent, and want to sit up, under normal circumstances, you have to stay up until you are in your fifties, and this is still when everything goes well, if there are some twists and turns in the middle, it is possible to stop at the position of the head of the public security bureau of a certain county below.

And he, who is only 29 now, has been promoted to the head of the second section of the search, chatting and laughing with a group of old men from his father's generation, relying on his undercover in the organization over the years, and obtaining a lot of intelligence, and performing well in destroying the organization······ This is a real feat.

Of course, there are also elements of political exchanges between the eastern and Kansai parties, as well as the connections of some of our ancestors.

But in any case, he is now a powerful figure who is not too big or small·······

"Why the hell am I so obsessed with catching the boss with my own hands?"

He couldn't help but ask himself.

Perhaps······· It's to live up to the original intention!

That year, after graduating from the police academy, he and his friend Date Hang talked about their usual ambitions while enjoying the cherry blossoms.

"This country is full of injustice, corruption, darkness, on the surface seems to be very stable, but there is a bigger crisis lurking in the shadows, we as police officers, I am afraid to see the deeper dark scenes of this country!"

"If that's the case, let's bring about a change, IDA, there are some things that have to be done by someone to make a difference."

Yes, I am here to change the country, this is the original intention of joining the public security and choosing an undercover organization!

In order to change this country, I must be in a high position, stand taller, and gain more power, so that I can have the ability, from the top down, to change this backwater country!

This perverted and sick country has long been rotten!

Consortiums manipulate parliamentarians, political donations have become the norm, the people at the bottom are numb and powerless, and European and American ghosts are eyeing them······· It's already to the point where if you don't change, you die!

Itahang, we used to be under the cherry blossom tree, and we agreed to be together.

Thinking of that year, when the white cherry blossoms fluttered and fell one after another, and the two of them complained to each other under the tree, and promised to dedicate themselves to the country and the people, he lifted his spirits, and the anxiety in his heart was relieved a lot.

There had never been a moment when he felt so deeply that the soul of his friend Date Hang was not far from him, with him.

"It's a day, is that you?"

He felt a sense of peace that he hadn't felt in a long time, a feeling that could only be felt when he was with friends who could trust each other for the rest of his life.

In the vision that ordinary people can't see, a little white shadow gradually shows its figure, and it can't see clearly, standing silently three feet behind him, stretching out his hands, blocking some invisible power for him.

Circles of ripples rippled around the white shadow, and the conflict between the two forces made the white shadow seem a little vain.

On the third basement floor, in the hub room of the otherworldly magic position, Lin Zhengyang and Xiao Ai stood up in surprise at the same time, and said in unison:

"Soul!"

"Date Air!"
