Wilderness Challenge for Live Broadcast

Audiences:……

Anyone can tell that Xu Ye's words are modest. In fact, he probably has already figured out the swamp environment.

We're so worried about you!

Yeah, we thought you wouldn't get used to it in the swamp, and you were caught up by other contestants in the end!

Grandpa Xu: I've already paid! Program crew: I understand!

...

Looking at the barrage, Chen Xu shook his head and said, Although I'm no stranger to the swamp environment, we still can't take it lightly.

Just in 2016, a light plane en route to Papua New Guinea crashed into a forest swamp due to engine failure, killing 12 people.

After the air traffic control received the distress message, it immediately sent a search and rescue team to start a rescue. It took two full days to find them.

The survivors who survived at that time were only 4 people. The rest were either swallowed by mud or bitten by poisonous insects and died of poisoning.

Yes, the swamps are divided into low, medium and high level swamps, that is, oxygen-poor, medium-oxygen, eutrophic swamps, and forest swamps, which is the environment in front of us, are exactly eutrophic swamps.

There are many animals and plants in the environment here, ranging from crocodiles and anacondas to nematodes and bacteria, which are very dangerous, because you never know what kind of terrifying creatures are lurking under the water!

have to.

Asahi's examples started again.

Just when the audience wanted to make barrage jokes, Lina suddenly coughed twice, then took off her vest, got wet, and covered her mouth and nose: Chen, we have to get out of here first, my throat is already starting to feel uncomfortable !

Chen Xu nodded, and covered his mouth and nose in the same way.

Hydrogen sulfide is easily soluble in water, so in the short term, we can use soaked cloth as a filter to prevent our respiratory tract from being irritated too much.

You should know that even low-density hydrogen sulfide still has the risk of loss of smell and even conjunctivitis, while higher-density hydrogen sulfide can poison and die within an hour, with a concentration of 1000, It can be fatal in an instant!

So, sometimes it smells like rotten eggs,

On the contrary, it is a good thing, because the high concentration of hydrogen sulfide will quickly paralyze the olfactory nerve, so that you will not notice the abnormality.

But you don't have to worry about it in the wild. Under natural conditions, the highest abundance of microbial degradation and reduction is only 2%. As long as you are careful, there is no fatal danger.

In the swamp, Chen Xu explained the danger of hydrogen sulfide to everyone while covering his mouth and nose.

Lina also added that the area where hydrogen sulfide can accumulate is generally an anaerobic environment at the bottom of the mud, just like many swamps will emit tiny swamp bubbles.

But Chen Xu also said before that this is a large oxygen-rich swamp, and anaerobic areas rarely exist.

so.

After walking for tens of meters, Lina took off her clothes. Sure enough, the surrounding air immediately smelled much fresher.

Chen Xu simply twisted the vest over the water and put it on.

Because the water level of the swamp is below their knees, it doesn't matter if the clothes are dry or not.

call……

He took a breath and looked around. Except for the land tens of meters behind him, the other three directions looked almost exactly the same. Except for the trees, it was the water full of aquatic plants and garbage.

As we all know, the swamp is one of the most disorienting wild environments. The water here is very muddy. You may not be able to see the current situation of Lena and me.

Our feet are almost completely covered by the mud at the bottom of the water. Yes, the mud bed at the bottom of the swamp is very soft. Every step we take, we need to go through three steps: pulling out, sinking in, and pulling out again.

It looks like walking in thick snow, but the density of mud is higher than that of snow, and it is much heavier than the latter.

Once you get lost here, even if you don't get eaten by the crocodile, you will die of exhaustion, so we have to find a way to confirm a rough and accurate position...

After saying the last sentence, Chen Xu raised his head subconsciously.

The audience knew at a glance that Master Xu was looking for the sun. Anyone who watched his live broadcast knew that using the sun to identify the direction is one of the most common ways to survive in the wilderness.

But embarrassingly so.

The oxygen-enriched swamp has lush vegetation, just like the trees on the mountains. The large canopy blocks the sky, making it difficult to see the shadow of the sun.

Chen Xu also seemed to have given up on using it. It's hard to find the position of the sun. Although you can see it by climbing up a tree, there are many ways to tell the direction. We still need to waste energy for the time being.

I don't know if you still remember a method of identifying orientation that I demonstrated in a lake in Borneo, Indonesia, by judging by the direction of water flow!

Water flow judgment?

Does the swamp have water?

Some people in the live broadcast room couldn't help asking questions.

Lina nodded: Of course the swamp also has a flow direction, but its flow is so slow that we can hardly notice it, but since there are many organisms in the oxygen-enriched swamp, it must be a complete circulatory system, so the water cannot be dead , definitely living water!

right!

Chen Xu took over the conversation.

While Lina was teaching the audience about science, he had already caught a dead branch soaked in the water, then took out the paracord and tied it to a tree trunk, and threw it into the water again with a plop. .

The stick is floating, and if the water is flowing, it must move in the direction of the flow.

The method couldn't be simpler.

But the difficulty is that you have to know the environment very well.

First of all, you have to know which direction the water is flowing in!

Chen Xu possesses platinum-level wilderness peak skills, and his wilderness knowledge is already top-notch in the world. Coupled with the all-terrain survey in the special forces skill group to collect environmental information, he has already figured out the terrain here.

The swamp in northern Argentina is located between the Andes Mountains in the west and the Gran Chaco Plain in the northeast. It is about 50 kilometers long and distributed in blocks.

Affected by the river left by the western mountains, its general flow direction is from west to east. Although it flows very slowly, it can only flow about 20 meters a day, but it does flow.

As Chen Xu spoke.

The dead wood that was thrown into the water barely moved, and most of them were swaying slightly indiscriminately following the waves of the water that fell into the water for the first time.

It seems it will take time.

While waiting, Chen Xu and Lina naturally didn't just stand here stupidly, but started looking for some food to replenish energy.

The oxygen-enriched swamp does have a lot of life, but likewise, there are a lot of snakes and crocodiles.

Often the places where food is easiest to obtain are also accompanied by great crises.

Chen Xu must plan ahead.
