Live Wilderness Adventure

Chapter 334 Senior Welder

Bi Fang raised his head and walked into this huge space, like an ant crawling into the Forbidden City in the middle of the night.

The sound of footsteps echoed in the empty factory, not in a hurry.

[Is Lao Fang not in a hurry? Wouldn't the explosion just now attract other people? 】

[Jiayi, shouldn't he find something and slip away at this time? 】

"It doesn't matter."

Bi Fang shook his head, he didn't care about this, or he thought of it long ago.

"It's not an exaggeration to describe Ye Yimen with a small burst in three hours and a big burst in five hours. Besides, it has just rained, which is when everyone is very tired. It’s an instinct engraved in DNA to avoid frequent time periods, and I only dare to engage in such a big battle because of this, otherwise it’s not worth taking such a big risk just to show you an explosion.”

The water friends were amused, remembering Bi Fang's joke about passing by not to be missed.

There is another point that Bi Fang did not say. For some reason, the rebels and the army did not really enter the center of Yeimen. Only some thugs and gangs are not too willing to approach some dangerous places. The reason for the explosion does not matter. There is no need for these people to figure out things.

People cherish their lives.

The first moment they saw the explosion, normal people walked around, and so did the gangsters. There were still people joining in the fun when this happened, most of them in safe cities.

People living in Yeimen will never be like this.

After spending half an hour walking around the factory, Bi Fang probably figured out the layout here. At this moment, he stopped and looked at the room excitedly.

The water friends didn't know why, why Bi Fang started to smile inexplicably when he got here, until he moved a box as a foothold, and wiped the dusty sign on the door of the room.

Ministry of Defense!

This is an English card, but the drone's screen automatically gives appropriate translations based on different regions.

[Holy shit, is it a security office? 】

[What kind of security, people call it the Department of Defense, look at the name, how foreign]

【...Isn't this English? It's all translation problems, the translator's fault! 】

[The waiter behind the scenes: I took the blame for it! 】

[There really is! 】

[Fuck, go in and see if there is something good, will there be a gun? I really want to know! Ahhhhh! 】

Suddenly seeing a place where there might be weapons and equipment, the water friends were all very excited, wishing they could kick open the door now and go in to search for it.

pity.

Bi Fang turned the doorknob, but did not move.

Still locked.

Taking two steps back, Bi Fang suddenly rushed forward and slammed into the door sideways.

There was a loud noise, but nothing happened except shaking off some dust, and the door seemed unbreakable.

[It's over, is this the rhythm of bombing again? 】

【Blasting Maniac Fangshen.gif】

[Good guy, isn't it a jpg now? Are you starting animation? 】

[When I have money, I must buy a mobile phone that can view pictures]

[Looking at the wolf tooth barrage, just around the corner! 】

Bi Fang looked around, shook his head, and broke the water friend's idea of ​​wanting to see the explosion.

"It can't be bombed anymore. The inside of the factory is no different than outside the factory. There are a lot of sundries here, which can easily cause a fire. If you really want to blow up, you have to clean it up. It's very troublesome and not worth it."

[Ah, what should I do? 】

Some water friends cheered at the right time, although they were anxious, but seeing Bi Fang's confident appearance, he knew that he must have had an idea in his heart.

"We can burn the lock through!"

Bi Fang spoke amazingly, and the light in his eyes was amazingly bright!

"The factory must have had a power outage. We can't use many facilities, but one thing is still available. Remember the acetylene cylinders and oxygen cylinders outside the factory building? We can actually use them normally, equipped with a gas welding torch, and use gas welding to close the door. Just burn through the lock."

The advantage of gas welding is that it does not need electricity. When welding is needed in places where the power supply is insufficient, gas welding is very effective. As long as the pressure of the bottle body is adjusted, the gas will be released automatically, and it can be used by lighting a fire. It is very suitable.

The audience was taken aback by Bi Fang's idea, and then found it ridiculous.

Normal usage?

As the co-author, you also admit that what you just said is not a normal usage, right?

If you could do this earlier, why did you fry it in the first place?

Bi Fang scratched his head and laughed: "Isn't there no gas welding gun? It would be great if I could find the bottle. I can't weld without a gun."

Walking around the factory, Bi Fang came to a place according to his memory. If he remembered correctly, the gas pipeline was laid behind this wall.

Following the gas pipes extending from the wall, Bi Fang found many acetylene cylinders and oxygen cylinders again, and found two cylinders with sufficient gas and pressure, as well as several pipes and welding torches.

The things were very heavy, so Bi Fang moved them to a small cart, pushed them to the door of the defense department, and started to connect the equipment.

The audience who watched the skillful movements were stunned for a moment. Is this the so-called all-rounder?

Can you even weld?

【Now I really want to open Shen Fang's brain to see what's inside】

[Add me, it's too fucking outrageous, you can even weld, what else can you not know besides having children? 】

[Learn mathematics, physics and chemistry well, and you will not be afraid to travel all over the world. The ancients never deceive me]

[The end of the world is here, I'm sure, Lao Fang must be the one who survives to the end]

"Haha, there are so many skills that you don't overwhelm yourself. I used to have a friend who was engaged in welding, and I followed him to learn a few things."

After Bi Fang connected the equipment, he opened the main gate of the oxygen cylinder and adjusted its output pressure to 0.3-0.5Mpa, and then opened the main gate of the gas cylinder to adjust its output pressure to 0.3-0.5Mpa.

I also specially showed it to the water friends, while explaining the movements, it seems that I really want to teach them...

"Turn on the gas valve of the welding torch, and then use an open flame to ignite the torch nozzle. I just forgot to use the ignition, and now we have to start the fire again. This time I will teach you a new method, without using car antifreeze."

Bi Fang put down the welding torch, and took out potassium permanganate from his bag, but instead of taking out antifreeze, he took out a small glass bottle filled with small white particles.

Opening the lid, Bi Fang poured out a little in the palm of his hand and swallowed it in one gulp in front of everyone.

[Should live, Fang Shen is sucking white powder! 】

【…】

【What is this? salt? 】

"It's white sugar, I didn't expect it."

Bi Fang broke off two pieces of wood from a table, poured some potassium permanganate and white sugar on the wood pieces, and explained.

"Potassium permanganate contacts, rubs, and collides with organic matter, which will generate heat and release oxygen, which will cause combustion. We mix one part of sugar and two parts of potassium permanganate, and grind them in the middle of dry wood chips. If the weather is dry, the wood chips are very Fast burn, short duration, great results. It only takes a few minutes."

"By the way, I forgot to say before that potassium permanganate is a strong corrosive agent. When using it, do not touch it directly with your hands, so as not to burn the skin. Only when it is made into a reasonable concentration can you directly touch it. I did not use it directly twice. , Once it was poured on a sponge, this time it was a piece of wood, I don’t know if you have noticed.”

Bi Fang grabbed another piece of wood to cover it, and then began to rub against it. After a few strokes, he felt that the wood piece began to heat up.

It started smoking in less than a minute and successfully ignited the flame in just three minutes.

The audience watching was stunned.

"So you must always have potassium permanganate in your home. It is a real good thing that can clean wounds and purify water sources. When fetching water in the wild, add three or four grains of potassium permanganate to 1 liter of water and drink it in 30 minutes. If you get lost, you can still make a mark."

"Especially when plant poisoning is accidentally ingested in the wild, we need to lavage the stomach as soon as possible. In order to reduce the absorption of toxic substances, the simple method is to lavage the stomach with potassium permanganate solution with a concentration of 1:1000-1:4000. And the concentration is still very good Matching, 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 gastric mucosal ulceration, and it must not be used for gastric lavage. So pay attention to safe use. "

Bi Fang talked about a lot of benefits in one breath. He only mentioned a few sentences before, and now he explained it seriously.

If not, who would have thought that a common disinfection item would have so many particularities and uses?

"So learning is really important. If you are good at mathematics, physics and chemistry, you will have most of your wilderness survival skills."

The water friends are even more admired by Bi Fang's erudition. They can speak clearly and logically with just a bottle of common medicine. It is by no means a fluke that they have reached this point, but continuous accumulation.

[Fuck, is this thing so useful? 】

[I was so scared that I quickly placed an order and bought three boxes of potassium permanganate for dinner]

[Speaking of which, who did you bring the goods to (dog head)]

[Bring goods? My fist is hard! 】

[Don't scold, don't scold, you are learning, you are learning, and the children are useless. 】

With an open flame, Bi Fang approached the welding torch, as if igniting a fire, an orange flame instantly ignited at the mouth of the welding torch.

Open the oxygen valve of the torch, and finally adjust the oxygen control knob and the gas control knob.

With the oxygen output, the temperature of the flame rose rapidly, and after a while, the blazing light blue flame made everyone refreshed for a while.

Bi Fang came to the gate with a welding torch and burned it on the doorknob. After a while, the handle began to burn red and soften.

That's awesome!

Is this an advanced welder?
