After successfully lighting a fire, Chen Ya immediately got busy, first of all, he picked up six plastic bottles, all of which were placed on the ground one by one, two of which were 550 ml mineral water bottles, and now they all contained some river sand and small stones, which he had collected by the island water before.

The other four bottles, three are 500-700ml beverage bottles, such as Nutrition Express, iced tea, etc., and the last one is a 1.5-liter large Coke bottle, although all of them have no bottle caps, but they do not affect the use.

At this moment, the drone had already flown down and began to shoot at close range, and Chen Ya also looked at the camera and said:

"Now, I'm going to use the materials in my hands to make two simple filtration devices. ”

As he spoke, Chen Ya picked up a mineral water bottle, poured all the river sand and small stones on the ground, and then used a blue crystal blade to cut off the bottom, and then put it upside down.

It looks like a funnel, and in the process, Chen Ya is also explaining:

"Although the Yangtze River is a freshwater river, due to the rain in the morning, the soil upstream is washed away by the rain, resulting in the river water is very turbid, obviously contains many impurities, if you drink it directly, it will definitely make you upset. ”

And even if there are no impurities, the seemingly clear fresh water in many large rivers actually contains many harmful germs and even ...... It's schistosome. ”

Don't be smart and think that there are no bloodsuckers in the Yangtze River, in fact, Beihu is the hardest hit area of bloodsucking disease, schistosomiasis has been raging along the Yangtze River, and when the epidemic is serious, it even makes some sections of the Yangtze River unsuitable for swimming.

"So, if you want to get clean drinking water, you need to filter it anyway. ”

After Chen Ya finished speaking, the tourists in the live broadcast room were blown up! All kinds of barrages rolled rapidly.

"It's all about you: bloodsuckers?

"If you don't complain, you'll die: that, although I don't want to say it, I still can't help but pick a prick, the anchor has jumped over the Yangtze River before, aren't you afraid of being infected with bloodsucking worms?"

"Soul Wandering West Heaven @ If you don't complain, you'll die: Are you showing your sense of existence? Or do you want to see Brother Ya infected with bloodsucking worms?"

"Christmas fried sauce: Can you stop talking about it? ”

......

Seeing the barrage, Chen Ya smiled, raised his hand and took out a box of antibiotics from the tactical backpack, and then said:

"Rest assured, I have prepared a box of antibiotics, which have an inhibitory or killing effect on pathogenic microorganisms. ”

Although antibiotics may not have a strong killing effect on bloodsucking insects, Chen Ya is afraid of his own resistance, even if he is infected, there are praziquantel tablets that kill bloodsucking insects on sale in the system mall.

Anyway, as long as there is a system, Chen Ya can continue to die without any scruples, and the tourists in the live broadcast room, after seeing the box of antibiotics, were relieved, obviously still worried about his life.

After a while, there was already some charcoal in the fire, Chen Ya picked it out with a stick, waited for the charcoal to cool, then crushed it into powder, and then began to make a filter device.

In the hole-shaped plastic bottle, two layers of river sand, small stones, and charcoal are laid successively, of which sand can remove larger sediments in fresh water, charcoal can clean water quality, and small gravel can increase trace elements.

Finally, Chen Ya tore a piece of cloth from his otter-bitten clothes, sealed it at the bottom of the funnel bottle, and began to filter the fresh water.

Using an empty bottle to fill the paint bucket with muddy river water, Chen Ya put the filter device upside down on the mouth of the bottle of the nutrition express line, and then began to pour water above the hole.

Rushing!~

However, after the originally very turbid river water slowly seeped out of the filtration device, most of the scum had been removed, and the color had become transparent.

Under the light of the fire, the visitors in the live broadcast room, through the camera of the drone, can clearly see that the transparent fresh water finally flows into the nutrition express line at the bottom.

"99 Tanuki: Brother Ya is awesome! This thing is actually the same as my water purifier. ”

"The Cold of the End: The routine is completely correct, and the firm is complete!"

"Soul Travel: Thanks to the demonstration made by the anchor, I feel like I have learned another trick!"

"Tiger Roaring Mountains and Rivers: Don't BB anymore! I just care about when I can cook crabs and eat them?"

"Blood Pupil: Haha, boil crabs and eat +1"

"Boiled Crab+10086"

......

Chen Ya couldn't help but smile when he saw the barrage, and then made a filter device again, which could also speed up the filtration of the water source, and the filtered fresh water was all packed into the 1.5-liter Coke bottle.

It took about half an hour, and after the big cola bottle was filled with clear fresh water, Chen Ya stopped filtering, then grabbed a handful of dead grass, and then began to clean the algae and burrs on the crabs in the paint bucket.

This kind of freshwater river crab needs to be cleaned before it can start to stew, but when it comes to river crabs, Chen Ya can't help but laugh.

When he was a writer, he had dealt with the river crab god countless times, but he didn't expect to be on a small island in the river tonight, but he was going to prepare to eat river crabs.

After washing all the river crabs with withered grass, Chen Ya immediately poured out the river water in the bucket, then picked up the Coke bottle, poured a little filtered fresh water into the bucket, and cleaned it again.

As long as there are conditions, Chen Ya is still quite hygienic, but if there are no conditions, even if it is eaten raw, he will not frown, but the current situation has not yet reached that extreme level.

After the ingredients and fresh water were all processed, Chen Ya poured the whole bottle of filtered fresh water into the bucket, and then brought three large stones, put them on the side of the fire in a zigzag shape, and then put the paint bucket on the shelf.

Under the continuous heating of the flame, the metal bucket began to heat up slowly, simmering this pot of freshwater crabs, maybe the food is a little single, and even with such a large paint bucket, more than a dozen river crabs were cooked, which was really overkill.

But because of the time, Chen Ya didn't have time to get more food, and he had just arrived at the Three Gorges of the Yangtze River not long ago, and only five or six hours had passed so far, and it was already very good to be able to find a small island to rest that night and have a little food.

In this regard, the tourists in the live broadcast room are very satisfied, and now they are all looking forward to the picture of the anchor eating crabs, while Chen Ya is sitting by the fire, feeling the warmth of the flames, and then smiled:

"When the water boils, it's ready to eat. ”

Uh-huh!~

At this moment, the sky was completely dark, and Chen Ya, who was sitting in front of the fire, suddenly heard a childish cry, and by the light of the fire, a gray figure gradually appeared on the outer wall of the stone circle, which was the otter who had left before.

Seeing the little otter, a happy color appeared in Chen Ya's eyes, he was worried that Lao Tzu's pot of crabs was not enough to eat, you came just in time!

Hurry up to my pot!
