Heavy rain washed over the ground and poured into the car through the cracks in the doors, leaving a pool of water.

"Can't live ......"

Wrapped in an oilcloth, Bi Fang, who rushed back to the camp in the heavy rain, frowned.

The shelter that had been built with great difficulty was destroyed by a heavy rain, and his heart was quite melancholy.

Outside the eaves, it rained heavily, and the rain was filled with thick smoke, and the visibility was less than 20 meters, and it was white and unclear from 30 meters away.

The raindrops collided and shattered in the air, falling into a stream of water foam, mixed with the cold, looking for every crevice and sparing no effort to burrow.

Bi Fang stood under the eaves, and shivered violently when he was penetrated by this cold air, but soon, the fox meat in his abdomen that had not been fully digested turned into a warm current that reinvigorated him.

The rain drenched his forehead, and he reached back, only to squeeze two strands of hair from between his fingers and hang down from the corners of his forehead, and the faint light of the sky gilded his dark back.

"It doesn't matter, the camping site can be rebuilt, as long as you pay attention not to catch a cold, the body is the capital of the revolution, it is also very common to encounter this kind of heavy rain in the wild, you don't have to be too pessimistic, whether it is a person or an animal, it is rare to act in such weather, which is good news for us."

The worse the weather, the less people want to go out, and the same is true for gangs, which is an excellent time for "vulnerable groups" like Bi Fang.

Thinking of this, the unpleasantness of the destruction of the campsite was washed away by the heavy rain, Bi Fang no longer felt cold, but was full of energy again, thinking about where to search for supplies next.

"We've already been to the south of the industrial zone, so we should go in a different direction and look east, and I think there are cooling towers, which are hyperbolic shapes."

Bi Fang gestured with both hands on two curves, cooling towers are actually very common, watching movies as a child, the decisive point between Wolverine and Deadpool was on the edge of the cooling tower.

At that time, I didn't understand much, and I thought that this kind of tower was the symbol of a nuclear power plant, and I didn't know it anymore, and I subconsciously wanted to go around when I saw it, but when I grew up, I knew that large steel plants and power plants would also have this kind of thing, which was not an uncommon thing.

"Cooling towers are different from ordinary tall and thin chimneys, which are cooling equipment, which are generally used in large factories, such as chemical plants, steel plants, power plants, and there are many good things in these plants, and no matter which one of them, we should be able to collect something that is useful to us."

Determining the direction, Bi Fang wrapped the oilcloth tightly and rushed into the rain again.

One of the advantages of traveling in the city is that once you are familiar with your surroundings, you can easily recognize the direction, unlike in the forest, even if you return to the camping site, there are no markers, and you need to judge the direction again when you look at almost the same trees.

In the past, the front of the factory was south, so the east side naturally went out and turned left, and then it was good to keep going in this direction.

Rainwater flowed across the streets.

Matthew Hal was running in the rain, but he couldn't find the familiar figure.

Gradually, he couldn't run, his whole body seemed to be filled with lead, and the heavy dizziness was about to overwhelm him, and countless rains fell to the ground and exploded together, and he swirled, his eyes were dazed, and in a trance it seemed that there were walls all around, surrounding him.

Modern warfare is information warfare, and signal base stations are the key targets, and in addition to satellite signals, several other communication methods have been cut off.

Matthew knew this very well Du Ming, and specially prepared a satellite mobile phone, but the mobile phone was accidentally lost in the previous escape......

The last scene in my memory was a campfire in a factory, and I don't know where it went after that.

Is it possible to find a man in a ruined city by sheer luck?

Matthew regretted that he had a hot head, quit his job that everyone envied, returned to the front line, and even deliberately chose the same city after knowing the other party's destination.

But you can see it all, how can you ignore it?

He has seen countless tragedies happen, and countless times he has been unable to do anything but record the atrocities on camera.

But here the man is!

He must have a way!

……

Bugs that fall into puddles and are about to drown are constantly struggling, and the roads are damp and muddy after the rain.

One foot deep and one foot shallow, Bi Fang's upper was wrapped in a layer of mud, he put down the tarpaulin, shook it gently, the water droplets rolled off the tarpaulin, folded and put it away, he took the sailors to observe the destination, and his heart was faintly excited.

Ten minutes ago, Bi Fang climbed over the fence and wanted to enter the factory, but was blocked by the door again, so he had no choice but to find a way to enter the interior again, and walked around the factory, but he never thought that there was an unexpected discovery.

Inside the walls, the factories are lined up next to each other, and between the wide aisles, there are laid pipes everywhere, naked outside the walls.

Bi Fang held the steel bar and knocked on the steel pipe, the sound of Qingyue was endless, he came to an iron box, inserted the steel bar with a light car, and pried it out.

"This kind of iron box is actually not strong, just a thin layer of iron, which is easy to pry open, but everyone must be careful, it is likely to contain flammable and explosive gas, do not use too much force, causing tragedy."

Stuck into the steel bar along the gap, the iron sheet creaked, and soon there was a bang, and the iron door was directly twisted and deformed, breaking free.

Pulling open the iron door, there are two large cylinders inside.

Bi Fang wiped the sign, pointed to the two large cylinders in surprise and said, "It's acetylene and oxygen!" ”

He looked up at the huge factory: "This kind of gas pipe erected outside the building is not common, it should be for the convenience of the workers, I think it will be a steel plant, because the combination of acetylene and oxygen, the most commonly used place is gas welding, acetylene is a combustible gas, oxygen is a combustible gas, the two are mixed and ignited, the temperature can even reach 3,000 degrees, and it is not a problem to burn steel." ”

Hearing Bi Fang mention gas welding, many water friends suddenly became excited.

[Damn, I did this at the beginning of this semester's metalworking internship, and the temperature was high, so I directly melted the iron box. 】

[, why is it so familiar, it turned out to be gas welding! 】

[Can this thing still be used?] 】

[It's one thing whether it can be used or not, in fact, I'm more like knowing if it will explode (dog head)]

Bi Fang took two steps back, looked at the orderly laying of pipes, and a bold idea emerged in his heart, and he high-fived him with a fist.

"Acetylene and oxygen are very unstable and volatile when they mix together, but at the same time, if you know what you're going to do, you can make the most of it, what can you do with a bunch of combustible stuff mixed together?"

What can you do?

Flammable and explosive!

There is no need to point it out, the audience naturally thinks of this, and thinks about so many gas tank explosions, isn't it also a truth?

Acetylene might be even more powerful!

[Lao Fang, you want to make a bomb? 】

[Out of breath, Fang Shen]

[It's out! 】

[Strictly require the official to use satellites to supervise Fang Shen's every move, and never let him get out of the monitoring, otherwise it will be extremely dangerous (dog head)]

[You are Fan Ma Kajiro? 】

Bi Fang smiled and began to twist the knob on the cylinder, probably because it took a long time, there were some rust spots on the knob, and it creaked when it was twisted, and the audience trembled when they heard it, for fear that the moment they unscrewed it, there would be an explosion.

"Just now I was looking to see if there were ventilation ducts that would allow me to enter the factory, but now it seems that it is not necessary, we can make it simpler, the way to get in.

There is ample evidence that many flammable materials can actually be made into makeshift bombs, but this is definitely a professional field, so don't try it easily, just watch it fresh, so don't miss it when you pass by, I'll live demo this time, and if you miss it, you can only watch the recording. ”

Bi Fang made a joke with the audience, and at the same time had the purpose of attracting the audience to stay, after all, except for catching a fox today, it hasn't opened much.

The official is also very cooperative, and the wolf tooth and metube are very cooperative to send a push again, and the title is Ruined City: Bifang Blasting the Gate.

The title was eye-catching, and after a while, the number of live broadcasters began to rise gradually, and it rose by 100,000 in just ten minutes!

[Snap, soon, I came in when I saw the title, I heard that it was going to be blasted, I hope Fang Shen's tail juice, don't engage in some title parties]

[Plus one, is this really going to be blasted? Did the old side get explosives? 】

[I was still at work just now, and I came in when I saw this title, indicating that I didn't want to miss it.] 】

[There is no explosives, but there is a bottle of acetylene]

Looking at the audience who had just poured in, Bi Fang explained his situation and purpose again, but he couldn't figure out the water friends, and they were all excited, and they all wanted to see what the real blasting was like.

As he spoke, a small cylinder of less than one meter had been unscrewed, and Bi Fang checked it, it was very heavy, probably yes, but this was basically the weight of the cylinder itself.

Carrying the cylinder to a side door of the steel mill, Bi Fang gathered some other materials around.

For soldiers and spies, entering buildings is a very important strategic and survival skill, and the special forces have bomb disposal training, which Bi Fang naturally understands, and the scope is even wider, because many places also involve more advanced chemical knowledge.

The key to door blasting and controlling the explosion is how to direct the force of the explosion to blow the door down.

Bi Fang looked around, and took a fancy to a large iron box, which was more than one meter high and more than two meters wide, with a small lock, but only a light prie, the iron box was pried open, and there were many sundries inside, linoleum and oilcloth, which were very heavy but useless.

Many factories will prepare some linoleum linoleum, the purpose is to be used to cover and shelter from the rain when it rains, so as to avoid many things getting wet and losing their effect.

This is also the reason why Bifang is so easy to find oilcloth, and in the industrial park, these things are the most lacking.

Sure that there was nothing good inside, Bi Fang grabbed the edge of the iron box and dragged it towards the gate little by little, explaining as he dragged it.

"Blasting is sometimes the only way to get into an enclosed building, and the key is to put a huge, heavy ballast in front of the blast target to stop the blast debris from ejecting there, and at the same time to aim the blast at the target, which in my case is aimed at the door locks and the hinges on the doors.

In fact, this is similar to bullet shooting, and the gun also uses the barrel to limit the direction of the bullet, so that it flies towards the target path, so as to concentrate the target. Here's a truth, but this ballast is not heavyweight enough, we can also stuff some stones and clods into it to increase its weight and avoid being blown up in the event of an explosion.

As for how to design the actual blasting part......"

Bi Fang, who blocked the door, took a breath and smiled at the sailors who were looking forward to it: "I won't tell you this, in our business, many tricks can't be passed on randomly, and it will be miserable to find me if something happens, but I am very confident that it is definitely not difficult to blow up this door." ”

The sailors were disappointed when they heard the first half of the sentence, and even thought that they were selling dog meat on the head of a sheep, but when they heard the second half of the sentence, they still smiled in understanding.

[You only discipline, I don't blame you (dog head) if something happens]

[Bang bang, open the door, I'm checking the water meter]

[Open the door, your express has arrived, quickly take it]

[One dares to teach, one dares to learn]

"Alright, we can get started."

Blocking the side door with an iron box, Bi Fang picked up the acetylene bottle and came to the ballast and the side door, put it in the middle card owner, and then put down the backpack and took out the bottle of antifreeze that he saw before.

"Ethylene glycol will burn and explode when exposed to an open flame, which is actually similar to gasoline, we can stuff a strip of cloth into it, soak it, and it can be used as a lead."

A thin strip of cloth was stuffed into the bottle, contaminated with ethylene glycol, and Bi Fang pulled it out again, wrapping one end around the mouth of the acetylene bottle, and pulling the other end out and out of the ballast.

The next thing is life to ignite the lead.

"In the ruined city, it is a little difficult to drill wood for fire, you should have seen it before, I wasted a lot of effort to light the fire, and now it has just rained heavily, dry wood is even more difficult to find, and it makes it more difficult to get rid of the fire, but after entering the factory, I found a good thing that can help us live quickly."

Bi Fang dug into his backpack, grabbed a small bottle, opened the lid, and under the dim light, it seemed to be full of black powder.

Potassium permanganate!

Many viewers who have been watching it immediately recognized what this "familiar" bottle was, which was potassium permanganate found in the previous medicine box.

But isn't this thing for disinfection and labeling?

Viewers with good memories still remember Bi Fang's statement at that time, that is, it is used for disinfection and marking, and the mark has to be in the snow, so what does it have to do with the fire now?

"It's a big deal, you haven't learned chemistry well, potassium permanganate is a strong oxidant, once you encounter a reducing agent, it will automatically decompose, emitting a lot of heat, these heat gathered, it is the best igniter, it is very convenient to make a fire, as for the reducing agent, we actually have ......"

Halfway through speaking, Bi Fang took out a large bottle in his bag again, and after a while, he took out a large bottle and shook it in front of the water friend with a smile.

And this bottle of reagent, the audience also knows it, it is the bottle of medical alcohol!

"Ethanol is one of the reducing agents that can make it oxidize and decompose, but unfortunately, not many people seem to be aware of it."

Bi Fang only brought a backpack to survive this time, and all the things in it were collected before, and the audience knew them, and there were very few who might connect them and use them.

With these things, it is very simple to start a fire, first Bi Fang tore off the sponge pad, as early as this morning before he set off this morning, he thought about the possibility of needing to live, so he tore some sea surface from the inside of the car in advance and put it in his backpack.

The surface of the sea is fluffy and soft, contains a lot of air inside, and it is dry and flammable, making it suitable for ignition materials.

Bi Fang first picked some weeds and put them on the lead wire, and then put a sponge pad on the weeds, separated by a layer of grass, to prevent the sea from burning too fast, and then he poured a little potassium permanganate, then a little medical alcohol, and stirred it well with an iron wire.

After a while, puffs of white smoke were seen.

After a meal at the acetylene bottle.

Bi Fang immediately ran out more than ten meters and hid behind a big tree, covering his ears.

Blasting, right now!
