Bi Fang raised his head and walked into this huge space, just like an ant crawling into the Forbidden City late at night.
The sound of footsteps echoed in the empty factory, neither urgent nor slow.
[Isn’t Lao Fang anxious? Won’t the explosion just now attract other people? 】
[Plus, shouldn’t you quickly find something and run away at this time? 】
"It doesn't matter."
Bi Fang shook his head, not caring about this, or he had already thought of it.
"It's not an exaggeration to describe it as a small explosion in three hours and a large explosion in five hours. What's more, it has just rained, which is when everyone is very tired. When it rains, it just rains, and all living things are very...
It is an instinct engraved in our DNA to have a period of time when we are less likely to be seen. I only dare to engage in such a big battle with this in mind, otherwise it would not be worth taking such a big risk just to show you an explosion."
The water friends were amused and remembered Bifang's joke just now about not to miss it when passing by.
There is another point that Bifang did not mention. For some reasons, neither the rebels nor the army really entered the center of Yemen. Some thugs and gangs were not too willing to get close to dangerous places. The explosion was not caused by any reason.
What these people want to figure out is not necessary.
Everyone cherishes their lives.
The first moment they saw the explosion, normal people walked around, and the same was true for gangsters. There were still people joining in the fun when something like this happened. Most of them were in safe cities.
People living in Yemen would never be like this.
After spending half an hour walking around the factory, Bi Fang roughly figured out the layout. At this time, he stopped and looked at the room excitedly.
The water friends didn't understand why Bi Fang started smiling inexplicably when he arrived here, until he brought a box to stand on his feet and wiped the dusty sign on the door of the room.
Ministry of Defense!
This is an English sign, but the drone screen automatically gives appropriate translations according to different regions.
[Holy shit, is this a security station? 】
[What's the security guard? They call it the Ministry of Defense. Look at this name. It's so foreign.]
[…Isn’t this English? It’s all a matter of translation and the fault of the translator!]
[Waiter behind the scenes: I’ll take the blame!]
【It actually does exist!】
[Fuck, go in and see if there are any good things. Is there a gun? I really want to know! Ahhhhh! 】
Suddenly seeing a place where there might be weapons and equipment, all the water friends were so excited that they wanted to kick open the door and go in to search.
pity.
Bi Fang turned the door handle, but it didn't move.
Still locked.
After taking two steps back, Bi Fang suddenly rushed forward and bumped sideways against the door.
There was a loud noise, but nothing happened except for shaking off some dust. The door seemed to be unbreakable.
[It’s over, is this the rhythm of another explosion? 】
[Explosion Maniac·Fang Shen.gif]
[Hey guys, aren’t they all jpgs now? Are they all moving pictures now? 】
[When I get rich, I will definitely buy a mobile phone that can view pictures]
[Watching movies on Langya Danmu is just around the corner!]
Bi Fang looked around and shook his head, breaking the friend's idea of seeing explosions.
"We can't blow it up anymore. The inside of the factory is no better than the outside. There are a lot of debris here, which can easily cause fires. If we really blow it up, we have to clean it up. It's very troublesome and not worth it."
【Ah, what should I do?】
There were water friends who complimented him at the right time. Although he was anxious, looking at Bi Fang's confident look, it was clear that he must have had an idea in his mind.
"We can burn through the door lock!"
Bi Fang's words were astonishing, and the light in his eyes was astonishingly bright!
"The factory must have lost power, and we can't use many facilities, but there is one thing we can still use. Remember the acetylene bottles and oxygen bottles outside the factory? We can actually use them normally, with a gas welding gun, and use gas to weld the door.
Just burn through the lock."
The advantage of gas welding is that it does not require electricity. When welding is needed in places where the power supply is insufficient, gas welding is very useful. Just adjust the pressure of the bottle to automatically deflate it and light a fire to use it. It is perfect.
The audience was startled by Bi Fang's idea, and then found it ridiculous.
Normal usage?
Co-author, you also admit that what you just said is not normal usage, right?
If you could have done this earlier, why did you have to blow it up in the first place?
Bi Fang scratched his head and laughed: "Isn't there a gas welding gun? It would be great if I can find the bottle. I can't weld without a gun."
After walking around the factory, Bi Fang followed his memory and came to a place. If he remembered correctly, behind this wall was a gas pipeline.
Following the gas pipe extending from outside the wall, Bi Fang once again found many acetylene bottles and oxygen bottles, two bottles of gas and sufficient pressure, as well as several pipes and welding guns.
The things were very heavy, so Bi Fang moved them onto a small cart, pushed them to the door of the defense office, and started to connect the equipment.
The audience was stunned as they watched the skilled movements. Is this the so-called all-rounder?
Can you even weld?
[Now I really want to open Fang Shen’s brain and see what’s inside it]
[Add me in, that’s too damn outrageous. You can even weld. Apart from giving birth, what else can’t you do? 】
[Learn mathematics, physics and chemistry well, and I will not be afraid of traveling all over the world. The ancients have never deceived me]
[The end of the world has come, I am sure that Lao Fang must be the one who survives to the end]
"Haha, I have so many skills that I don't feel overwhelmed. I used to have a friend who was engaged in welding, so I followed him and learned both skills."
After connecting the equipment, Bi Fang opened the main gate of the oxygen bottle and adjusted its output pressure to 0.3-0.5Mpa. Then he opened the main gate of the gas bottle and adjusted its output pressure to 0.3-0.5Mpa.
I also specially showed it to the water friends, explaining and performing the movements at the same time, as if I really wanted to teach them...
"Twist open the gas valve of the welding gun, and then use an open flame to light the nozzle of the welding gun. I just forgot to borrow the ignition, and now we have to light the fire again. This time I will teach you a new method without using car antifreeze."
Bi Fang put down the welding gun and took out the potassium permanganate from his bag, but did not take out the antifreeze. Instead, he took out a small glass bottle filled with small white particles.
Opening the lid, Bi Fang poured a little bit into his hand and swallowed it in front of everyone.
【It’s my birthday, Fang Shen sucked the white powder! 】
【……】
【What is this? Is it salt?】
"It's white sugar, I didn't expect it."
Bi Fang broke off two wood chips from a table, poured some potassium permanganate and white sugar on the wood chips, and explained.
"When potassium permanganate comes into contact, friction, and collision with organic matter, it will generate heat and release oxygen, which will cause combustion. We mix one part sugar and two parts potassium permanganate and grind it between dry wood chips. If the weather is dry, the wood chips will be very
It burns quickly, the time is short, and the effect is good. It only takes a few minutes."
"By the way, I forgot to mention before that potassium permanganate is a strong corrosive. When using it, do not touch it directly with your hands to avoid burning the skin. Only when it is formulated into a reasonable concentration, you can directly touch it. I did not use my hands directly twice.
, once it was poured on a sponge, this time it was wood chips, I don’t know if you paid attention.”
Bi Fang grabbed another piece of wood and covered it, and then began to rub it. Within a few moments, he felt the wood piece starting to get hot.
It started to smoke in less than a minute and successfully ignited a flame in just three minutes.
The audience was stunned for a moment.
"So you must always have potassium permanganate at home. It is a really good thing. It can clean wounds and purify water sources. When fetching water in the wild, add three or four capsules of potassium permanganate to 1 liter of water. You can drink it in 30 minutes.
You can still mark it if you get lost.”
"Especially when poisoning by accidental consumption of plants in the wild, we must lavage the stomach as soon as possible. In order to reduce the absorption of toxic substances, the simple method is to use a potassium permanganate solution with a concentration of 1:1000-1:4000 to lavage the stomach. And the concentration is very good.
To match, just look at the color, it can be lavender or light red.
If the solution is purple or deep purple, its concentration has reached 1:100-1:200. This extremely high concentration of potassium permanganate solution can cause ulceration of the gastric mucosa. It must not be used for gastric lavage. So pay attention to safety.
use."
Bi Fang talked about a lot of benefits in one breath. He only mentioned a few sentences before, but now he explained them seriously.
Otherwise, who would have thought that a common disinfectant item would have so many particularities and uses?
"So learning is really important. If you are good at mathematics, physics and chemistry, you will also know most of the wilderness survival skills."
Friends in the water are even more admired by Bi Fang's erudition. He can speak clearly about a common potion. It is not a fluke to reach this point, but a continuous accumulation.
[Holy shit, this thing is actually so useful?]
[I was so scared that I quickly placed an order and stocked up three boxes of potassium permanganate to eat]
[Speaking of which, who are you bringing the goods to (dog head)]
【Bringing goods? My fist is hard!】
[Stop scolding, stop scolding, keep learning, keep learning, the children have all failed.]
With an open flame, Bi Fang brought the welding gun close to him, and the muzzle of the welding gun instantly ignited an orange flame.
Open the oxygen valve of the welding gun, and finally adjust the oxygen control knob and gas control knob.
With the oxygen output, the flame temperature increased rapidly, and soon the blazing light blue flame made everyone feel energetic.
Bi Fang came to the door with a welding gun and burned the door handle. After a while, the handle began to burn red and soften.
