Live Wilderness Adventure

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

　　 The drone flew high in the sky, and the water friends watched attentively at the group of sponges that were so small that they were almost invisible, but within half a minute, the yellowish-brown spot suddenly brightened.

　　 got it!

　　 The flame spread quickly along the string, climbing up like a small snake, twisting and twisting, opening a snake kiss full of flames, and biting fiercely!

　　 The loud noise made people lose their hearing for an instant. A white shock wave spread visibly to the naked eye, and the spewing flame was like an oversized welding torch. The hot wind softened the steel and the glass shattered into pieces.

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

The water friends looking down from a high altitude stared, their hearts leaked in the sound of the explosion. I can’t believe that in this scene, the concrete floor should have been gray and white, but it would turn black because it was soaked by rain. And discoloration, instantly turned white...

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

　　 Even Bi Fang, who was leaning against the tree, felt that his back was gently pushed, showing the strength of the impact.

　　 The thick water mist condensed into water droplets, and it fell on the patter, and the ground was wet again, but it was not soaked yet, and the remaining high temperature evaporated the water again.

　　 When the wind blows, it disappears invisible.

　　 No one changed the angle and came to Bi Fang.

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

　　 Water friends can only see Bi Fang sitting on the ground calmly drinking water, with smoke billowing behind him, as if everything had nothing to do with him.

　　 Ten minutes later, after confirming that there was no second explosion, Bi Fang wiped the dust off his shoulders, walked out of the big tree, and looked at the thick smoke coming out of the side door. It was not surprising.

Bi Fang stepped forward to the gate and stepped on the cracked ground and said: "Because of the high carbon content of acetylene, it will burn with thick smoke and the temperature is very high. You see, the cement floor here is very high. It turns white, which means that the water has been evaporated. It is a terrible high temperature."

　　 Hearing Bi Fang’s analysis, the water friends who were frightened by the power of the explosion were dumbfounded. It is such a heart that can directly look at such an explosion.

　　 This is much more shocking than the grenade explosion in the film and television drama. The ground turned from black to white, cracked inch by inch, and the iron door was brought to a height of several meters by the shock wave, and it began to deform and fall to the ground in the air.

【horrible? I don’t look as scary as you]

　　【Fang Shen is super calm】

　　 [Nonsense, all we have seen are life-and-death crisis several times, let alone missed it, it’s so awesome, I was blown up]

　　【Taishan collapsed in front and the same color, Milu Xingyu left without blinking, Fangshen will not be Fangshen, awesome, I am the ruthless 666 machine! 】

　　 [After all, it is acetylene, and the explosion temperature is much higher than that of ordinary bombs, right? 】

"Yes, acetylene can reach three thousand six hundred degrees in oxygen combustion, even in the air, it is more than two thousand degrees, far exceeding the high temperature of a general bomb explosion, and the melting point of iron is only one thousand five hundred degrees. If it weren't blown up, it might already be a pool of molten iron."

　　 "When you encounter this kind of explosion, don't rush in, because you don't know what is behind the door. In case there are flammable and explosive materials, it is dangerous. Even if you are sure that there are no such things, be careful of fire extinguishers."

　　 Fire extinguisher?

　　 Cao Lifeng, who was about to return to the dormitory after dinner, glanced at the fire extinguisher and didn't care. What should I be careful about with this thing? Isn’t it used to put out the fire?

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

In addition, the fire extinguisher's carbon dioxide flame-retardant dry powder, foaming agent and other ingredients may be exposed to high temperature and chemical reactions may occur, resulting in an increase in the pressure in the bottle. At this time, a slight bump may cause an explosion, and the explosive power is very terrible. .

　　 In 2007, when a porter used an expired dry powder fire extinguisher in a warehouse in a certain wholesale market in Shenyue, the fire extinguisher suddenly exploded and the porter Wang was killed on the spot.

In 12 years, Mr. Lin, the shopkeeper of Shop 405, Yantan Furniture Market, Lanzhou City, heard an abnormal sound from a scrapped dry powder fire extinguisher at the door. He leaned over to see what happened. At this time, the fire extinguisher suddenly exploded and Lin was seriously injured. …"

　　 hiss!

　　 Cao Lifeng gasped, only to feel that the surrounding temperature had risen. He stared at the fire extinguisher in the corner, calmly moved away, walked around, and went upstairs on the other side of the corridor.

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

While 　　 was speaking, the smoke and flames at the door had dissipated, Bi Fang took out a towel, covered his mouth and nose after being soaked in water, Weng said.

"Let’s go in and take a look. Everyone should be careful before going in. Although carbon dioxide and water vapor are generated by the combustion of acetylene, there is still a lot of dust formed by the explosion, so be careful. The safest way is to cover it with a wet towel. Keep your mouth and nose, and be careful anyway."

　　 Prepared properly, Bi Fang put on his backpack and came to the explosion place, which was even more shocking.

　　 The iron box that was originally used as a ballast was blown up, and the tarp inside was burned to black charcoal long ago, and it merged with the molten iron box around it.

　　 squeezed a piece of the wall, and a small pinch turned it into yellow gray.

　　 raised his foot and entered, the water friend's gaze was instantly attracted by a touch of red on the wall, a formal fire extinguisher, but the distance was far away, and it seemed that it was not affected by the explosion.

　　 However, the rust on the handshake still shocked the water friends who knew that the fire extinguisher would explode.

　　 Ordinary days are okay. Naturally, someone is responsible for inspections and maintenance, but Yemen has been warped for a long time, and their lives can’t be saved, so there are people who care about small fire safety?

　　 Even Bi Fang cautiously walked around. When UU read www.uukanshu.com to avoid the fire extinguisher and enter the factory, he felt that it was all worthwhile.

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

　　 The internal facilities of the factory are complete, except for the absence of people, they are almost the same as usual!

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

　　 Looking at the empty factory, the water friends were all amazed.

too big.

　　 [Unbelievable, this place is too big, right? 】

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

　　 [Yes, the larger the place, the greater the possibility of good things, hasn’t the Lao Fang said that. 】

"It's not just the wilderness that gives the sense of vastness and horror. It is too big and scary. This is a huge abandoned factory building. I guess it is at least the size of four football fields and the height of a cathedral. .

　　 The workers had left long ago, but other creatures began to move in. Let me go, let me see what good things are here. "

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

　　 He can't help his inner desire to explore!
