Bi Fang jumped directly from the stone, walked along the stream for a hundred meters, and then returned to the starting point.
"No matter which water source you choose, be sure to observe whether there are animal carcasses and feces around, and whether the water body has any peculiar smell or strange color."
Leonardo held the kettle and looked around cautiously, fearing that he would see something that he shouldn't see...that shouldn't appear.
"The best choice is a stream that flows down from a high place and flows quickly...too fast is not good as it will bring along the sediment at the bottom. A shallow stream with a lot of rocks at the bottom is the best choice."
"We are lucky. The water in front of us is a relatively good water source. Running water does not rot, and it is difficult for bacteria and protozoa to exist in large numbers in such water.
In addition, the water flowing down from a high place and passing through layers of stones has been filtered for the first time. There are almost no large particles in the surface water of such a stream, and even some colloids in the water will be deposited at the bottom."
There are many such streams in rainforests and forests.
Abundant rain will fall from high places and flow to low places day after day, washing out streams.
"This kind of water is the most delicious." Bi Fang picked up the water in his hand and took a few sips, then smacked his mouth. "Okay, it just doesn't have a weird smell."
"Other water sources, such as lakes, are inferior choices. The bigger the lake, the better. Small lakes are less mobile, conducive to the growth of bacteria and protozoa, and tend to have an odor."
【What does it smell like?】
[Don’t think too much, I just want to know what it tastes like.]
"You asked me what it smells like?" Bi Fang dragged his chin and thought for a while, "I think it smells like fish poop."
Ah this.
Leonardo was stunned for a moment and began to think about what the smell of fish poop was.
"The water in large rivers and lakes is generally not drinkable directly. If you have to, you can use clothes, gauze, and tea bags to filter it in advance and then use a filter to filter out other impurities and harmful substances.
It is best to boil the water for five minutes to 100% kill the microorganisms in the water, including viruses. However, it cannot completely remove the particles and magazines in the water, and it cannot remove the odor of the water, which is more troublesome.
You can also use a portable ultraviolet irradiation pen, which can be inserted into the water to irradiate the water body, which can kill all microorganisms at a speed of about 90 seconds per liter. It cannot remove large impurities in the water and cannot reduce the odor of the water, but it will not introduce new odors.”
Bi Fang explained various key points of water sources, while Leonardo held the kettle and waited for the pills to take full effect.
In the hot environment, the two of them traveled for two hours and lost a lot of water, making them extremely thirsty.
After replenishing the water, Bi Fang simply washed his face, then took out the green snake from the funnel bag and performed simple processing and cleaning.
Leonardo shook the kettle in his hand and said warily: "Can I drink it?"
"Drink." Bifang smiled. Leonardo was frightened out of his ptsd, and he was 100% vigilant about anything that entered his mouth.
"Water purification tablets are a common item in the wild. The main ingredient is sodium silver chloride compound. This species will react when it encounters water. The silver ions and chloride ions in it will have corresponding effects and eliminate the protist organisms in the sewage.
And some bacteria, fungi, viruses and other debris."
"Some water purification tablets will simultaneously precipitate most of the particles and colloids in the water, and the action time is about fifteen minutes. They cannot reduce the odor of the water, but the tablets themselves have a slightly pungent smell that can cover up the odor of the water."
"The water purified in this way can even be stored for a long time, but if the water quality is serious, it is often not enough to purify the water with water purification tablets alone. However, in my opinion, the water quality here is at a level that can be directly drank.
"
"But I'm not worried at all." Leonardo grimaced, a little puzzled.
Now that he thought about the scene just now, he still felt like vomiting.
Unfortunately, Bi Fang did not have any container to store water, so he directly took out the snake's stomach, washed it repeatedly, turned it over, and finally soaked it in water.
Anyone who has seen the animal world should know how well the snake's stomach accommodates, and it is definitely one of the best in the animal world.
After soaking for a while, it will be a good water storage container, able to hold at least about one and a half liters of clean water.
After doing all this, Bi Fang started tinkering with the red mud again.
"We need to mash all the herbs we collected directly. You can use two stones to grind them into crumbs. You don't have to be too particular about it. We only need its ingredients."
Throw the ground herbs into the red powder and mix thoroughly. Bifang takes up the water from upstream and pours it into it, and starts mixing it with the mud.
The whole process is very simple, because this is not kneading the dough, but stirring it into a slurry.
Soon, a pot of red mud appeared in front of the audience. It looked a bit like red facial cream, and the whole thing exuded an oily sheen.
Leonardo got closer and smelled it, and there was a strong plant fragrance. If he hadn't seen the entire production process, he might have thought it was a new product from a beauty salon!
【I actually feel pretty good?】
【Is it an illusion? 】
[I seem to be watching some primitive documentary...]
[How did Lao Fang do it without any sense of disobedience]
[I won’t watch the next Lord of the Rings Elf Prince if he’s not Fang Shen.]
The audience was a little surprised, it felt so weird!
Bi Fang was not polite. He already had several large bites from mosquitoes on his arm. He directly scraped out a bunch, rubbed it with both hands, and smeared it all over his body.
The pot of mud in front of me looks dark red, but once it is spread and applied to the body, it turns into a bronze color!
It was not as unbearable as the audience originally imagined, but instead intensified the wildness of the jungle. The originally fair body turned directly into a bronze color, as if it had been exposed to the sun for a long time.
The moment the red mud touched his body, Bi Fang felt a comfortable cooling sensation.
After being baked at high temperature into powder, the whole ball of red mud is basically in a sterile state. Added with water and herbs, it is very cooling and makes the bites from poisonous mosquitoes no longer itchy.
Leonardo on the side was not to be outdone. He tied up the cuffs of his hands and applied a ball on all the violently exposed torso, which also turned into a bronze "native".
When less than half of the large pot of clay was used, the two people had completely changed their "skin colors". They looked at each other and laughed in unison.
"Okay, I finally finished the mosquito repellent, and now it's time to have lunch."
Bi Fang sat cross-legged on the ground, dug a pit, put the charcoal he had taken earlier into it, quickly lit a flame according to the re-ignition method, and placed the cleaned bamboo leaves on top of the charcoal fire.
"If you can clean the poison glands, then it's best to clean them. If you can't, it doesn't matter. Just roast them completely. They are essentially proteins, and they will be denatured and inactivated at high temperatures."
The snake meat tumbled over the charcoal fire, and Leonardo's stomach also tumbled.
But the only thing no one noticed was that a flash of white flashed past among the bushes not far away.
