In less than 5 minutes, 3 litres of water were obtained, and as the sand dug down, the more water was extracted.

Xiao Lingfeng was digging diagonally, and the actual location had been dug under the boulder, and with the cover of this big stone, the moisture in the ground had been preserved.

"Actually, we could have taken water like this, and we didn't have to drink those disgusting camel waters. Duan Xuerong looked at the full bottle of water with satisfaction.

The water wasn't very clean, and there was some fine sand and dust in the water, which was better than disgusting camel water.

"Look, this is the water I squeezed out of the sand, because it contains impurities, I can't drink it directly, but I can purify it by making a simple water purification device. ”

Xiao Lingfeng flipped through Duan Xuerong's backpack and found a very small mineral water bottle from it, as well as a few high-temperature belts, these daily necessities were very helpful for surviving in the wilderness.

"Everyone knows that the water purifier is mainly to filter the impurities in the water, so that the quality of the water is more pure, and you can also use some simple tools to make the water purifier in the wilderness, and the effect is absolutely very good. ”

Xiao Lingfeng took a few pieces of charcoal from the temporary shelter last night and kept them in his pocket, which should be able to be used when necessary.

"Charcoal has a strong adsorption capacity, and the last time I was on a desert island, I used charcoal powder to brush my teeth because I didn't have toothpaste, and this time I can use these large pieces of charcoal to fill the water purification device. Xiao Lingfeng cut the bottom of the small mineral water bottle so that the mouth of the bottle was facing down.

"You can make a water purifier with a mineral water bottle, are you teasing me?"

"I really haven't seen anyone who can use bottles and charcoal to make water purifiers, now I won't say anything and just watch how Brother Feng operates. ”

"Brother Feng's existence is to make everything impossible possible, this thing is hanging in the wild, even crocodiles dare to do it!"

"I'm going to see Brother Feng's sharp and expressive operation again, the bottle water purifier, I'm looking forward to it!"

Seeing Brother Feng's unfortunate expression, I knew that he was going to pretend to be forced again, and it seemed that he was going to succeed. ”

"If you have the ability to pretend to be stupid, you can't pretend to be stupid~! Brother Feng has always belonged to the former. ”

"Hey~!Someone is going to pretend to be a demon, yes! That's right, it's that crocodile guy!"

There is no precedent for survival in the wilderness in this parallel space that is basically similar to the region, Xiao Lingfeng opened this type of precursor, in the previous earth, the charcoal water purifier was really simple, and few people used it here.

"First of all, I had to fill the bottle with something very absorbent, and I used this rag to fill the bottom of the bottle, remembering to fold the rag very thick, so that the diffuser density of the rag was as small as possible." ”

"Then put in some charcoal, and this hay, and then put in this gravel, just fill this water purifier!"

After Xiao Lingfeng made the water purifier, he prepared a high-temperature bag, and now he has no water storage containers, only these high-temperature bags.

"Whoa~!"

The turbid water in the bottle is poured into the water purifier, and the water slowly flows out of the bottle, but the water is turbid and has a trace of black impurities.

"Didn't you say that this is a water purifier?Why is it getting darker and darker?" Duan Xuerong held the high-temperature bag, looking helpless and dazed.

I just saw that the product was full of confidence, this one was shown, why did you make such a big foreign appearance?

"2333333 thought I was going to pretend to be forced, but I didn't expect to fail to pretend to be forced~!"

"Congratulations to Brother Feng for pretending to fail, what about the special water purifier, the sewage device is almost the same, now, the water is even dirtier~~ ahhahahahaha~~!"

"Pay attention to Brother Feng's sharp eyes, it doesn't seem that he is pretending to fail!"

"Is there a follow-up move, how will Brother Feng operate, now insert an advertisement, and the advertisement will be more exciting~!"

"Little Chrysanthemum Grandma's class has started, the child uses boiling water to water the flowers, and always throws thumbtacks into the pigsty, what should I do?"

"It's mostly wasted, just take a beating. ”

Xiao Lingfeng looked helpless, this group of animals took the opportunity to mock themselves whenever they had the opportunity, but he didn't care, this was normal.

"It is normal for the water purifier to be in this situation, the water flows through the charcoal and the dead grass and gravel, and the fine impurities in it will flow out along the water, everyone knows that the house is leaking, so as to prove that the penetration of water is indeed very strong, and after these impurities are washed away, it can play a role in water purification. ”

Sure enough, the water that flowed out of the water purifier in less than 10 seconds was extremely clear, and Duan Xuerong also changed to a clean bag to hold the water.

"Wow~!You're so amazing~!These waters are really clear!" Duan Xuerong praised excitedly.

To be honest, being praised by such a beautiful girl with bright eyes and bright teeth, I feel that my heart is hairy, as if there is a cute kitten scratching my heart.

The kitten should be snow-white all over, its claws are not very sharp, it doesn't scratch it very hard, its whiskers are long, and its eyes should be sapphire-like.

No matter what Duan Xuerong thinks, she will not be able to make this guy think of a cat because of her small expressions and words, and even the color of the fur can be clearly seen.

The water in the bottle was all purified, and the three of them began to drink heartily, which looked very pure and quite refreshing.

"In this scorching desert, it is better to drink some cool water, and I squeeze all this water out of the sand, and it only needs a little simple purification treatment to instantly turn it into refreshing mineral water." Xiao Lingfeng drank happily.

The cool pure water expelled the heat, and the originally hot body became much refreshed, and it was best to drink some water after being thirsty for a long time.

"I'll go, this operation 6666666~!"

"I admire Brother Feng a lot, this guy's operation is too powerful. ”

"What is the principle of the water purifier, why does it come out with brown water at the beginning, which looks so dirty, and then it comes out with clean water?"

Xiao Lingfeng explained, "The loose structure of charcoal makes it have many tiny voids, resulting in a very large surface area, which is in full contact with water, adsorbing tiny particles and pigment molecules in the water, thus purifying water to a certain extent." However, charcoal particles can also pollute water bodies, so they also need to be filtered. ”

"I'll go, Brother Feng is so knowledgeable, the extreme environment of the desert can't bother him, is this guy really Superman?"

"Superman, do you like to help grandma cross the street?"

I'm Superman, "I used to like to help my grandmother cross the street, but since I was blackmailed a few times, my flight panties have been repaid~!"
