Xu Xingguo quickly left the sewage drainage channel.

Liquid nitrogen.

This thing is very useful for bomb disposal.

Just now, Zhuang Yan asked Long Bin to inform the Ga Bureau’s Special Service Office to prepare this thing.

Generally, liquid nitrogen barrels are an indispensable thing in anti-terrorism bomb disposal, and are also called liquid nitrogen treatment systems.

In fact, it is just a steel barrel or iron barrel filled with liquid nitrogen.

Liquid nitrogen is a colorless, odorless and volatile liquid with a relative density of 0.808, a melting point of about -209 degrees and a boiling point of -195 degrees.

Generally, liquid nitrogen barrels are used to store explosive objects, because the temperature in the liquid nitrogen barrel can drop to -198 degrees. After most substances are placed, their physical and chemical properties will change, which will cause some explosive objects to fail for a period of time. For example, the lightning/tube will not take effect after being placed, and for example, explosives will also lose their activity.

However, this liquid nitrogen barrel is usually used to deal with small explosions, such as residual mortar shells, landmines, etc. If it is inconvenient to disassemble it on the spot, it can be placed in the liquid nitrogen barrel and transferred to a safe area to be destroyed.

This Type 97 bomb is too big and has a broken body and is in an unstable state. Solemn dare not move this thing rashly.

However, since it cannot be put in, you can freeze it by pouring it directly on the bullet body.

Although the effect is not as good as the liquid nitrogen soaks directly, it is also a way.

Old Xu ran back quickly with the liquid nitrogen bucket, and quickly put on his mask and gloves.

"I'll fall."

"Okay." Zhuangyan pointed to the crack: "This cracked crack and the fuses are poured on me."

After saying that, he stepped aside.

Xu Xingguo opened the liquid nitrogen pump and pulled out the valve, aimed the nozzle at the bullet body, and began to slowly step on the pump.

The liquid nitrogen at the nozzle began to flow out, landed on the bullet body, and immediately vaporized.

The entire sewage drainage channel suddenly became white and mist.

Because it is not as good as the soaking effect, Lao Xu has to pour the liquid nitrogen into it.

Taking advantage of this time, Zhuang Yan began to assemble his own bomb cutter outside.

This thing is the best cutter for water pipe bombs and military bombs.

It looks like a pipe, and the types of bullets used are also different depending on the part to be disassembled. Generally speaking, there are fork-type bullets, flat-head cutting bullets, blade-shaped bullets, cylindrical bullets and chisel-shaped bullets, etc.

The basic principle is that after excitation, the cutting bullet in the tube is shot out, cutting or destroying the target at an extremely high speed.

The solemn use of chisel bullets, with the purpose of destroying the rivets on the warhead part.

Just destroy it, the fuse part can be screwed out with tools.

All 20kg of liquid nitrogen was poured out.

The solemn cutter is also assembled.

Xu Xingguo said: "I've done it here."

Zhuangyan said: "Leave here, I will complete the rest."

Xu Xingguo seemed to want to say something, and opened his mouth and finally said only two words: "Be careful."

In fact, there is nothing to say. Now that the liquid nitrogen is falling, the fuse and the bullets at the cracks are all very safe.

The charge in the Type 97 6 Fanlu explosive bomb is Type 91 explosive, which is similar to Tiendi in terms of stability. In addition, it is now frozen by liquid nitrogen, so the safety should be very high.

After Lao Xu left, he solemnly set up the cutting device, aimed it at the rivet, and then pulled the lead to leave the sewage channel until he squatted behind the bunker thirty meters away.

The power of the bomb is very powerful, but it may not be the safest here. If you miss the game, your life will be in great danger.

Fortunately, the bomb is in the tunnel, and even if it explodes, its power will be greatly reduced. However, some buildings next to the sewage channel will inevitably be damaged. What's even more terrible is that there is a small gas station fifty meters away nearby.

No one can guarantee something will happen.

Zhuang Yan squatted behind the sandbag, checked the wiring connector, and after making sure there was no problem, he pressed the detonation button.

Bang—

A harsh metal impact sound came from the sewage channel.

Zhuang Yan stretched out her head and looked at the direction of the sewage channel, and there was nothing unusual.

I looked at the watch behind the sandbag and started timing.

After one minute, I stretched my head and looked at it.

Everything is still very quiet.

He breathed a sigh of relief.

No smoke, no explosion.

It seems to be done.

He took the toolbox and returned to the sewage drain again.

Lao Xu also came back.

"It's done?"

He solemnly inspected the hole left in the rivets in the fuse, and looked inside, and the rivets were cut off.

"It's done," he said.

"Then remove the fuse quickly." Xu Xingguo said: "The temperature has begun to rise."

He nodded solemnly, removed the large wrench from the toolbox, stuck it on the brass post of the fuse, tightened it and stuck it.

Xu Xingguo fixed the bullet body with something so that it would not be rotated with the solemnity.

"It's coming." said solemnly.

Xu Xingguo was sweating profusely, and he didn't know if it was hot or nervous.

After all, once this big guy is blown up, the two of them will definitely have no bones left, and it is lucky to be able to retrieve some parts.

Zhuang Yan slowly increased the force in his hand, and a dent appeared in the place where the brass fuse was card owner...

Rolling and rolling-

The friction sound of a metal makes people nervous.

Click—

Suddenly, the solemn hand sank two points.

Xu Xingguo's eyes suddenly doubled, and the sweat on his forehead became more layered, and he was dripping down.

Zhuangyan stopped.

Old Xu stared at the fuse and asked after a long time: "How is it?"

"It's loose!" A smile appeared on his solemn face.

"Good, I was scared just now!" Xu Xingguo also breathed a sigh of relief: "Hurry up!"

The solemnity began to twist slowly.

After twisting for half a turn, release the wrench, then stuck, and continue twisting...

It is not safe to have a fuse that leaves the bullet body for a moment.

Even though the fuse has loosened, no one knows what will happen next.

After all, it has been a decades-old bomb, and it is much more dangerous to dismantle old bombs than to dismantle new ones.

Xu Xingguo and Zhuangyan's camouflage uniform were soaked, sweat oozing out of the roots of their hair and flowing down their cheeks to their chin.

...

Longteng Hotel, in the Dragon and Phoenix Hall.

All the guests stared at the TV.

News from Linhai City and provincial TV stations both interspersed with the news that Linhai City construction units dug up bombs.

Now all Linhai citizens gather in front of the TV no matter where they are, at home, in shopping malls, or even on the streets.

People from the mall gathered at the place where LCD TVs were sold. People on the street gathered in front of the TVs in the convenience store, and everyone at home was on the sofa...

Even the most popular TV series is no longer followed tonight.

Lin Qingying sat next to her mother, her eyes never leaving the large screen LCD on the wall for a moment.

It was really quiet in the hall, and I was even very careful when I breathed.

Lin Jianjun was furious just now and almost called Zhuang Yan and asked him to come back immediately.

On the day of my wedding, I actually went to dismantle the bomb!

What is this!

If it weren't for the mother's stopping her, Lin Jianjun would probably announce the wedding immediately.

On the TV screen, a female reporter holding a microphone kept explaining the scene to the camera. A police light could be vaguely seen flashing in the distance behind her.
