Liu Danqing looked at the heavy rain outside and said, "It's raining hard outside, it's really a disaster, we can't go outside to look for food, we can only stay inside the shelter until the rain stops." ”

Now staying in the shelter, Liu Danqing knew that if he didn't find some topics or things, the audience would soon disperse, so he pondered for a moment and began to find topics from the materials they had now.

"Since I can't go out, I'm here to sort out the supplies we have and make some backup plans. ”

"First of all, my supplies, toothpaste, toothbrush, polyethylene sealed bag, a hiking bag with solar charging, unfortunately there has been no sun. A 50,000 mAh power bank can charge our mobile phones and drones, and I see, there is still about 30 percent of the electricity, so we have to reduce the time we use our phones now. A pair of underwear and a replacement quick-drying suit can make us drier and cleaner, improving our quality of life in the field. ”

"I looked in the bag, there is a small bundle of rope, which is also a must-have in the field, this is a 7-core 550 paracord, 30 meters long. 550 means that the weight that this paracord can bear is 550 pounds, which is equivalent to about 500 pounds, and it can be used to spend some extreme terrain. There is also a small strong light flashlight, in the field, don't count on the mobile phone light, you must prepare this strong light flashlight. ”

"Okay, my bag is basically empty, the biggest items, tents, blankets, and moisture pads have been washed away by the flash floods, and now I'm going to introduce my sapper shovel. ”

"Declare in advance, this is not an advertisement! This sapper shovel was bought by me for 300 Huaxia coins, and everyone saw it and helped me a lot, but in fact it also has hidden objects, and now I will show them one by one from the beginning. ”

"First of all, the shovel head, it can be adjusted at an angle, you see, I can adjust the shovel head to a 90-degree angle with the handle, so that it can be used as a hoe, especially useful when digging up some edible plant rhizomes, such as cassava, which is not easy to destroy with the planing method. ”

"Next is the handle, which has three sections, and in the middle section is a multi-functional knife, which can be attached to the top handle, which is easy to use, and everyone has already seen it. ”

"Next I'm going to introduce the items in the other two handles. First of all, the first section of the handle, inside is medical supplies, you see, this is gauze, needle and thread, used to bandage trauma, this is white medicine, the most widely used trauma medicine, these are anti-inflammatory drugs and antibiotics, in the field to prepare some, for life is a kind of protection. ”

"Inside the last vial is potassium permanganate, also known as GAO potassium manganate, which is a strong oxidizing agent. Not many people use it because it has a big taste and is also more corrosive. But in the field, it is a multi-functional good thing, so when the special forces members of various countries go out on a mission, they like to bring some of his functions, and I will pick the important ones and tell you about them. ”

"First of all, it is disinfection and cleaning the wound, and potassium permanganate has a strong bactericidal power. It is possible to rinse skin wounds, ulcers, abscesses, etc., with a solution with a concentration of 1:2000-1:5000. It can also be used to rinse the mouth to remove bad breath and disinfect the mouth. However, you must pay attention to the concentration when using, and it is better to be lighter than to have a worse effect than to be too thick. The simple way to test this concentration is to look directly at the solution, which is light purple or light red, if the solution is purple or dark purple, then the concentration is too high and corrosive. ”

"The second is gastric lavage, when poisoning plants by mistake in the wild, gastric lavage should be carried out as soon as possible to reduce the absorption of toxic substances, and gastric lavage can be used with potassium permanganate solution with a concentration of 1:1000-1:4000. Or look at the color, the solution is light purple or light red. ”

"The third is water purification, potassium permanganate is a conventional additive used in water purification plants. When taking water in the field, add three or four small grains of potassium permanganate to 1 liter of water, leave it for 30 minutes, let it have enough time to release oxygen to sterilize, and it can be drunk. ”

"The fourth is the road sign, when you get lost in the snow, you can sprinkle potassium permanganate particles on the snow, and the purple color produced after dissolving can guide the rescuers. However, the color is usually only stored for about two hours. If you see a rescue helicopter, then it's time to use this. ”

"The fifth is to make a fire, potassium permanganate can be used to make a fire, now I have at least one item here that has been used to make a fire with potassium manganate, that is this hard candy, after crushing the sugar, mixed with potassium permanganate, grinding it with a branch, it can produce fire, let's waste a candy, try it. ”

Liu Danqing peeled out a piece of candy, put it on a wooden pier, found a relatively straight branch, pulled it down, and crushed it on top of the hard candy, and soon, the hard candy was crushed into powder.

"Now, let's pour some potassium permanganate, we must pay attention here, it must be in a windproof place, if the potassium permanganate is blown into the eyes by the wind, it is not a joke, it may lead to blindness. We mix the two, and then we grind them on top with a twig, and we see that the smoke is already rising, and all right, it's on. ”

As Liu Danqing grinded for less than thirty seconds, an orange-red flame rose on the wooden pier, Xiao Weiwei squatted on the side excitedly and shouted: "It's on, it's really on", and the live broadcast room also exclaimed.

"The baby rabbit born in the Year of the Rabbit will give Weiwei a helicopter - Teacher Qingye, this is the tuition fee, please smile. ”

"Xiong Er gave Weiwei a passenger plane - strongly asked Qingye to come to our school as a teacher. ”

"Ma Da Ha loves Da Ma Ha to give Weiwei a helicopter - 666666666, Qingye Jungle Laboratory!"

Liu Danqing directly threw the wooden pier into the fire, destroying the corpse and destroying the traces to prevent potassium permanganate, a dangerous product, from harming Xiao Weiwei.

After processing the experimental items, Liu Danqing was about to get Xiao Weiwei's bag, but Xiao Weiwei grabbed her hiking bag and looked at Liu Danqing with a vigilant expression.

"Weiwei, come and give me the bag, the audience and friends are waiting to see it!"

"Don't give it, it's my private privacy, I can't give it to you!"

"Vivi, many people are dedicating themselves to science, and now it's just your bag that you give!"

"If you don't give, you won't give!"

"Vivi, just take a look, and don't snatch your bag. ”

"Don't give it!"

Xiao Weiwei clung to her mountaineering bag, took a firm stand, and had high morale! Let Liu Danqing mobilize in every possible way, but she just didn't hand over her bag.

The audience watching the live broadcast burst into laughter.

"Hahaha, why do I have a sense of immediacy when I look at Grandma Wolf?"

"Hehe, Qing Ye finally failed once!"

"It seems that looking at the Dongdong inside the Weiwei bag, will there be any surprises?"

"Xiao Weiwei, Master Qing has a lollipop here!"

Liu Danqing was helpless, so he had to retreat and asked Xiao Weiwei: "Weiwei, if there is anything in your bag that you can take out and display, I'll take a look." ”

Xiao Weiwei strained her face, glared at Liu Danqing, and said angrily: "No, it's all my privacy!"

But at the end of the day, she pulled something out of her bag.

"It's a flashlight, exactly like mine, couple, hehe. Here's the toothbrush toothpaste, like mine, a couple's set. The sealed bag is still exactly the same. These are the remaining three packets of daily nuts, which have a really good name, and now they really are a pack of daily nuts, which can replenish us with carbohydrates, sugar, and some vegetable oils. This is a pack of wet wipes, but in the wilderness area, wet wipes are not a good choice, large weight, single function, not as good as paper towels, in addition to being used as toilet paper, but also can be used as velvet when making a fire. There is also a pack of toilet paper, of course, I also want to apply to Weiwei every time I use it, hehe!"

"Vivi, anything else?"

Xiao Weiwei reluctantly took out another anti-cursion cream, handed a hand cream to Liu Danqing, and said, "It's really no longer there, you don't have to care about me anymore." ”

Liu Danqing laughed and said: "Okay, whether the audience believes it or not, I believe it anyway." ”

Xiao Weiwei was furious, waved her little fist, and said with a hammer: "Let you laugh at me, let you sarcastically mock me." ”

"Meng Meng didn't give it to Weiwei Helicopter - sprinkle dog food, sprinkle dog food again!"

"It's a lot of extra to give Weiwei a fighter jet - I like to see you guys take it seriously. ”

Liu Danqing took the two pieces of cosmetics, looked at them, and said: "Look at this hand cream, it contains glycerin, and it can also be used with potassium permanganate to make a fire, and it is simpler, as long as you squeeze some out, and then pour some potassium permanganate, as long as it takes a while, you can make a fire, now I don't have much potassium permanganate, I want to keep them just in case, so I won't test it for everyone." I'll show you another time I have the chance. ”

Xiao Weiwei looked at Liu Danqing with a resentful expression, and the purity of her eyes was comparable to that of Erha.

Liu Danqing was stared at by Xiao Weiwei and was furious, so she had to say: "Weiwei, there is really not much potassium permanganate, I can't afford to waste it!"

"Okay, I'll let you experiment with potassium permanganate and hand cream to make a fire before we go home, okay?"

"Hmph, who's rare!" Xiao Weiwei's passive skill, Tsundere, broke out again.

"I would like to remind you very seriously here that if you want to use potassium manganate for fire experiments, it is best to go outdoors, please be sure to take protective measures, in addition to fire prevention, eyes should also be specially protected, it is best to bring swimming goggles, safety first. After the experiment, be sure to extinguish the fire, and then dig a pit to bury the remnants of the experiment, so as not to cause a fire or harm others. ”

"Xiong Er gave Weiwei a passenger plane - thank you Qingye for reminding me, I am ready to buy potassium manganate and go home for experiments. ”

"Xiong Da gave Weiwei a fighter jet - thank you Qingye for reminding me and saving my house. ”

"Brother Qiang gave Weiwei a helicopter - I don't know why, I also want to thank Master Qing. ”

Liu Danqing didn't see the messages of these three goods, otherwise he would definitely have to sweat, and "Bear Infested" would have appeared in their live broadcast room.
