I just want to be a quiet and powerful person

As we go forward, the terrain gets lower and lower.

Ten minutes later, the two came to a low-lying area.

This low-lying area looks like a ditch. Broken tree branches can be seen everywhere on both sides and at the bottom of the ditch.

Seeing this, Lin Xian speculated:"This place should be a flood discharge point."

After that, he jumped into the ditch first, then turned around and took Mu Wanqing's hand, and carefully carried her down.

Such a considerate gesture made Mu Wanqing feel extremely sweet.

She pursed her lips and smiled and said,"Junior, there's no need to be like this. I'm not as delicate as you think."

She didn't want to put any extra burden on Lin Xian, and she was indeed not that fragile.

"Okay, then follow me!"

Lin Xian smiled slightly, holding the wooden stick and walking in front.

After walking for a long time, the front suddenly became clear.

In front of him was a flat depression, with large tracts of reeds blowing in the wind.

The two quickly found the water source. Only the reeds were visible. On the muddy ground, a small pool of water appeared in front of the two of them.

The water level was not high, only ten centimeters at most.

On the muddy ground around the water source, you could clearly see the footprints of various animals.

It was understandable that there was little water.

After all, this is downstream of the flood discharge point. It is mainly formed by the accumulation of water in the mountains when it rains.

During this period, the weather was relatively dry and there was not much rain.

Therefore, the accumulated water appeared to be very little.

But this is not the point. The key point is that this puddle is dirty.

Dirty in every sense of the word.

The water is very turbid and looks yellow and orange like juice. There are many reeds and dead leaves floating on the water, as well as many insect corpses... water The pool was too small, and it was stagnant water. It had no self-purification ability at all.

Seeing this scene, Mu Wanqing frowned and said,"Junior, this water looks like you can't drink it.""

"Of course not drink it!" Lin Xian agreed.

The content of bacteria, germs and microorganisms in this puddle is very high. Drinking it and having diarrhea is a trivial matter, but contracting parasites and diseases is a big deal.

Staring at this puddle, Lin Xian suddenly had an idea. He said:"Senior, is Heoka*001 still there?"

G*001?

In an instant, Mu Wanqing's face turned red.

She bit her lip and hesitated:"Isn't there something bad here...? Seeing that she had misunderstood, Lin Xian explained:"Uh...that's not what I meant. I thought of a way, but I need to use that box of things.""

"oh oh! Mu

Wanqing reacted, looking a little embarrassed and said:"Wait a minute, I'll look for it.""

After that, she stepped forward and opened the outer zipper of Lin Xian's backpack.

Seeing that the box of things was still there, Mu Wanqing took it out and handed it to Lin Xian.

"As long as it's still there, I thought those golden monkeys wouldn't even let go of this thing. Lin Xian teased.

Suppressing the shyness in her heart, Mu Wanqing asked curiously:"Junior, how do you plan to get water?""

She thought Lin Xian wanted to use the water to hold water, but then she thought about it and felt something was wrong.

Because the water in the puddle was obviously not drinkable.

This made her extremely confused and wanted to see how Lin Xian got the water. Lin Xian wanted to see how Lin Xian got the water. Xian smiled slightly mysteriously and said:"Senior sister, please sit down and rest for a while. You will have clean water to drink later.""

"All right!"

Mu Wanqing is indeed a little tired, mainly because of the fierce battle last night, which left her with some faint pain. She found a relatively clean place to sit down, Mu Wanqing hugged her knees and stared unblinkingly. Lin Xian.

He took a few steps back, squatted down about two meters away from the puddle, and then dug up the soil with both hands.

Because he was close to the puddle, the soil was very soft. Within a few strokes, Lin Xian dug out a 20 A centimeter-deep hole.

The deeper you dig, the softer the soil becomes, eventually turning into mud. At the same time, water gradually seeps out from the ground. There is more and more water in the pit, and soon most of the mud pit is submerged.

It's just that compared to puddles, the water in the mud pit is turbid, almost like mud.

Mu Wanqing raised her eyebrows and couldn't help but said:"Junior, are you sure the water in the pit is drinkable?"

"Although it looks dirty, it is actually dozens of times cleaner than the water in puddles. Lin Xian smiled and said

"real?"

Mu Wanqing was doubtful.

Lin Xian explained:"Of course. Since the water in the mud pit infiltrates from the ground, during the infiltration process, the sediment in the ground will filter out most of the dirt. It looks dirty now because the water is mixed with dirt. After the dirt settles, it will be clean."

It's a pity that there is no alum, otherwise it will settle faster.

Now, we can only wait slowly.

While waiting for the muddy water to settle, Lin Xian took out his dagger, cut off a piece of reed, and made a simple straw.

Then, In Mu Wanqing's shy eyes, he took out two Totos.

Lin Xian took out a piece of charcoal from the pocket of his jacket pants, cut it into small pieces, wrapped it in a piece of shredded wood, and finally stuffed it into one Totoo..

A simple water purifier was completed.

As for the other Taotao, it was used as a bottle to store water.

Seeing this, Mu Wanqing finally understood, and suddenly realized:"Water purifier?"

"That's right!

Lin Xian smiled and said:"The sediment is only the first layer of filtration, and it can only filter larger parasite eggs and impurities." Charcoal is the second layer of filtration, which can absorb smaller microorganisms and bacteria in the water."

While speaking, the water in the mud pit has almost settled.

As the soil particles sink, the water quality becomes countless times clearer.

Although it still looks a bit turbid, it is less than the 'orange juice' in the puddle. A lot.

Lin Xian waved and said,"Senior, please help me!"

"How to help?"

Mu Wanqing stepped forward and said expectantly.

"Just take this and catch the water." Lin Xian said, handing over the intact Totao.

After accepting the settings of the water purifier, Mu Wanqing became less shy about Totao.

After this camping experience, she felt that she might be able to use it again in the future. He couldn't look directly at this thing anymore.

Lying on the ground, Lin Xian put the charcoal bag filled with Tuolao into the puddle and started filling it with water.

I have to say that the quality of the Gang* brand is really good, it is light, thin and elastic.

At this time, the Taotao had turned into a huge water ball, but it showed no signs of damage.

After using a dagger to poke a few holes in the tip of the water ball, a series of clear water drops immediately flowed out along the charcoal bag.

Seeing this, Mu Wanqing hurriedly stepped forward, opened the bottle in her hand, and caught the water droplets.

The water filtered by charcoal was already very clear, at least it looked no different from tap water.
