This is a small oval pond, less than 40 square meters in size, which looks like it was dug by hand and has no downstream side.
The fishy smell in the air was stronger, making people feel nauseous.
A dense mass of green duckweed had huddled together, taking up almost a third of the entire pond.
Apart from the occasional bubble that pops up from underwater, the surface of the water is almost completely still.
After a moment of stunned silence, Ye Feng slowly walked to the edge of the pond and looked around.
When he saw the circle of withered grass on the shore and the skeletons of several animals, his brows furrowed even more deeply.
They seem dissatisfied with the water source here.
"Brother, what are you waiting for? Let's get going..."
Fu Changxiong was extremely thirsty and thought Ye Feng was afraid of danger underwater.
So he volunteered to pick up the kettle and prepare to fill it with water.
"stop!"
Ye Feng suddenly stopped him.
"What's wrong?"
"The water here is absolutely undrinkable."
Everyone could tell that the water was unclean.
In the wild, as long as you encounter flowing and clear water, it is generally safe to drink it directly.
However, stagnant water sources like this, under high temperatures and the presence of various plants and animals, can breed countless parasites and pathogens.
This is basic common sense in the wild.
But in their eyes, as long as it's boiled, there shouldn't be any problem.
The usually quick-witted Liu Sisi seemed to have noticed Ye Feng's worries.
"Brother Feng, is it okay to drink this water even after it's been boiled?"
"That's right."
Ye Feng nodded helplessly, his tone clearly showing disappointment.
"High temperatures can indeed kill about 90% of bacteria, but not all of them."
The remaining 10% is the most dangerous part.
Among them, the most heat-resistant Bacillus, Aspergillus flavus, and thermophilic bacteria are all bacteria that can withstand temperatures up to 250 degrees Celsius.
Boiling water has a boiling point of only 100 degrees Celsius. Even if you boil it for several hours, it's only equivalent to giving these germs a lukewarm bath.
"Once we drink this water, we're absolutely guaranteed to get malaria."
Upon hearing this, everyone licked their dry lips in disappointment.
They searched for nearly half an hour, thinking they had found a water source, but were now told it was undrinkable.
During the search, the water in everyone's kettles decreased by several kilograms.
For most of the day, they barely stopped wiping away sweat.
His entire body, even his underwear, was soaked.
In fact, all of these people, including Ye Feng, had already begun to experience mild dizziness.
If I hadn't replenished enough salt, I probably would have collapsed long ago.
"Hey!"
Suddenly, Liu Sisi raised an eyebrow, and an idea popped into her head.
"Brother Feng, I once saw an episode of Bear Grylls' survival show about finding water."
It seems like they dug a hole right next to this stagnant pool, and then…
"Then the mud in the mud pit will filter out most of the bacteria and parasites."
Finally, filter it several times using a sock or cloth, and then it's ready to boil and drink, right?
Ye Feng blurted out everything she wanted to say, leaving Liu Sisi speechless and only able to nod blankly.
"Give me a break. I've watched each of the 42 episodes from season 1 to 6 of Man vs. Wild at least five times."
When it comes to a passion for wilderness survival, you're nowhere near as passionate as I am.
The moment I observed this stagnant pool, I had already thought of this solution.
Until I saw them…
Ye Feng stretched out his finger and circled around the withered and dead plants at the edge of the pond.
"Remember, knowledge is static; people must learn to adapt to local conditions and apply it flexibly."
Especially in the wild, look at those plants, they're growing right next to a pond, yet they still die.
I should have known that the plants in the Amazon are all tropical and wouldn't be killed by the sun.
Therefore, there is only one possibility: a problem with the water source.
"This water is poisonous!?"
Liu Sisi only thought the water was unclean; as for whether it was poisonous, she had never really considered that possibility.
"Hmm. You could say that."
Ye Feng nodded and pointed to the bubbles that were constantly rising in the center of the pond.
“In this kind of stagnant water, fish generally cannot survive, and even if they do, they would definitely be dead long ago.”
So those bubbles mean that gas has been fermenting underneath.
Because it can't be discharged, it can only rise to the surface as bubbles.
This is the Amazon, after all. Think about it, what kind of gas could possibly kill these resilient weeds and plants?
Everyone looked at each other, completely bewildered.
Only Liu Sisi guessed some of the clues.
"Could it be... methane?"
"You're right."
Ye Feng gave her an approving look.
"It is estimated that within a year, all the plants here will die and become nutrients for this land."
It gradually turned into a swamp.
Then came the mangroves, which eventually became a habitat for bats and pythons.
Remember this: if you encounter water in this kind of environment in the wild, you must not drink it, no matter how thirsty you are.
Because human vitality and stomach capacity are far inferior to those of wild grass.
Even they can't withstand it, how can you possibly manage?
After saying that, Ye Feng turned and walked into the woods. The others reluctantly put away the jars and followed him.
It was already 4 p.m., and the group dared not travel any further.
Or perhaps they simply didn't have the means to travel.
Because there was very little water left in the jar, Ye Feng had to let them rest temporarily for safety reasons to reduce the loss of bodily fluids.
At this moment, everyone was slumped on their backpacks, leaning against the big tree, their eyes slightly narrowed.
They were covered in sweat, their clothes clinging almost entirely to their skin.
The tongue kept licking its lips, as if trying to alleviate some of the symptoms of dehydration.
It wasn't that they were particularly tired; it was just that at that moment, only two words were on their minds: drink water.
Ye Feng was in the same boat; he was already feeling his vision becoming somewhat blurry.
The intake is insufficient to cover the output; the amount of water consumed is far less than the amount of sweat excreted.
In addition to the waste of physical energy and the prolonged tension on the nerves, all organs of the body need water to function.
It's like when a car is running out of gas, the engine slows down; it's the same principle.
Ye Feng knew that this was a sign of dehydration.
He never expected that on their very first day away from home, the entire team would face a life-or-death crisis.
Dehydration in the rainforest—such a ridiculous thing, yet it actually happened.
However, Ye Feng wasn't without a way to find water.
However, this process is likely to take a long time, and they don't have much water left on them.
It will be dark in a little over two hours, and we still haven't found a place to stay.
If we were to find a stagnant pool of water at this point, it would be extremely dangerous.
