Bi Fang ran dozens of meters in a row, leaning against a big tree to block his ears.

The drone flew high into the air, and the sailors looked intently at the sponge, which was so small that it was almost invisible, but in half a minute, the yellow-brown point suddenly brightened.

It's on!

The firelight spread rapidly along the string, climbing up like a small snake, winding and twisting, opening the snake's kiss full of flame fangs, and devouring it fiercely!

The loud bang made people lose hearing for a moment, and a white shock wave spread out visibly to the naked eye, spewing flames like an oversized welding torch, and the scorching wind softened the steel, and the glass shattered into shards.

The black cement floor in a radius of several meters suddenly turned white, and then cracked and deformed.

The sailors who looked down from the sky widened their eyes, their hearts leaked in the explosion, and they couldn't believe the scene in front of them, the cement floor should have been gray and white, and it would have turned black because it was soaked in rain and changed color, and now it instantly turned white......

In the dazzling light of the fire, the iron gate twisted, was thrown into the air by the shock wave of the explosion, and rose to a height of several meters before falling again, slamming into the ground.

Even Bi Fang, who was leaning against the big tree, felt that he was gently pushed behind his back, which showed the strong impact.

The thick mist condenses into droplets, which fall down and moisten the ground again, but before it can be soaked, the residual high temperature will evaporate the water vapor again.

When the wind blows, it dissipates into nothingness.

The drone changed its angle and came to Bi Fang.

His brain was a little dizzy, so he didn't rush out, but took out his water bottle and drank some water to relieve his discomfort.

The sailors could only see Bi Fang sitting on the ground drinking water calmly, with thick smoke billowing behind him, as if everything had nothing to do with him.

Ten minutes later, after confirming that there was no secondary explosion, Bi Fang dusted off his shoulders, walked out of the tree, and looked at the smoke at the side door, not surprised.

Bi Fang took two steps forward to the gate, stepped on the cracked ground and said: "Acetylene has a large carbon content, so it will have thick smoke when burning, and the temperature is very high. ”

Hearing Bi Fang's calm analysis, the sailors who were frightened by the power of the explosion were dumbfounded, what kind of heart can look directly at such an explosion?

This is much more shocking than the grenade explosion in the film and television drama, the ground turns from black to white, inch by inch cracks, the iron door is carried by the shock wave to a height of several meters, and it begins to deform and fall to the ground in the air.

[Terrible? I don't think you're scary]

[Fang Shen is super calm]

[Nonsense, just what we saw were several life and death crises, not to mention that I didn't see it, it was so awesome, I was blown up]

[Mount Tai collapsed in front and the color remained unchanged, Elk Xingyu left and his eyes were not instantaneous, Fang Shen would not be Fang Shen,, I am a ruthless 666 machine! ] 】

[After all, it's acetylene, and the explosion temperature is much higher than the average bomb, right?] 】

"Yes, acetylene can reach 3,600 degrees in oxygen combustion, and even in the air, it is more than 2,000 degrees, far exceeding the high temperature of ordinary bomb explosions, and the melting point of iron is only 1,500 degrees.

"In the event of such an explosion, don't rush in, because you don't know what's behind the door, and it's dangerous in case there are flammable and explosive materials, even if you are sure that there are no such things, you should beware of fire extinguishers."

Fire extinguisher?

Cao Lifeng, who was about to go back to the dormitory after eating, glanced at the fire extinguisher and didn't care, what should I be careful about this thing? Isn't it just for extinguishing fires?

"Many people only know that the fire extinguisher can extinguish the fire, but the fire extinguisher itself is a high-pressure tank, the internal pressure is about ten times that of the atmosphere, under normal circumstances, the thick tank wall can effectively prevent the occurrence of explosion, but the expired fire extinguisher tank will be corroded by external pollution and thinned.

In addition, the carbon dioxide flame retardant dry powder, foaming agent and other components of the fire extinguisher are exposed to high temperatures, and chemical reactions may also occur, resulting in an increase in the pressure in the bottle.

In 07, when a porter used an expired dry powder fire extinguisher in a wholesale market warehouse in Shenyue, the fire extinguisher suddenly exploded, and the porter Wang was killed on the spot.

In 12 years, Mr. Lin, the owner of shop No. 405 of Yantan Furniture Market in Lanzhou City, heard an abnormal sound from the scrapped dry powder fire extinguisher at the door, so he leaned over to take a look, and then the fire extinguisher suddenly exploded, and Lin was seriously injured......"

Hiss!

Cao Lifeng gasped, only to feel that the temperature around him had risen, he looked at the fire extinguisher in the corner of the wall in a daze, moved his steps quietly, walked around, and went upstairs to the corridor on the other side.

"Well, there are many more similar cases, so I won't say more."

As he spoke, the smoke and flames at the door had dissipated, and Bi Fang took out a towel, covered his mouth and nose after dipping it in water, and said in a loud voice.

"Let's go in and have a look, we still have to be careful before we go in, although acetylene combustion produces carbon dioxide and water vapor, but the dust formed by the explosion is still very much, so be careful, the safest way is to cover your mouth and nose with a wet towel, in short, be careful."

Ready, Bi Fang put on his backpack and came to the explosion site, which was even more terrifying.

Most of the iron box that was originally used as ballast was blown up, and the tarpaulin inside had long since been burned into black charcoal, fused with the melted iron box around it.

I pinched the edge of the wall, and it turned into yellow ash with a slight pinch of it.

Raising his feet to enter, the eyes of the sailors were instantly attracted by a touch of red on the wall, it was the fire extinguisher, but the distance was far away, and it didn't seem to be affected by the explosion.

But the rust on the hand of the fire extinguisher still made the sailors who learned that the fire extinguisher would explode secretly frightened.

Ordinary days are fine, naturally someone is responsible for inspection and maintenance, but when the war in Yimen has been in turmoil for a long time, lives cannot be saved, how can anyone take care of a small fire safety?

Even Bi Fang carefully bypassed, and the moment he avoided the fire extinguisher and entered the factory, he felt that it was all worth it.

Standing next to the fence, looking down from here, the height alone is tens of meters high, looking at such a huge factory, an ambition arises spontaneously.

The factory is fully equipped with facilities, except for the absence of people, it is almost exactly the same as usual!

It means that this place has never been looted, or that the situation is critical, and there is no time to remove the equipment, in short, it is undoubtedly much better than the previous empty factory.

Looking at the empty factory, the sailors were all amazed.

It's too big.

[It's incredible, this place is too big, isn't it?] 】

[The bigger, the better, so that the security force is stronger, will there be any good things in the kitchen?] 】

[Yes, the bigger the place, the greater the possibility of having good things, didn't the old party say it. 】

"It's not just the wilderness that feels vast and terrifying, it's so big, it's frightening, it's a huge abandoned factory, I reckon it's the size of at least four football fields, and the height of a cathedral.

The workers had long since left, but other creatures were beginning to move in. Let's go, let me see what the hell is good here. ”

Bi Fang ran out along the fence and waved at the drone.

He couldn't help the desire to explore in his heart!
