When many viewers heard this, they couldn't help but be impressed by Xu Ye's profound knowledge again. Pen, fun, and www.biquge.info

After walking for a long time, there is a lot of stagnant water in this vicinity, but there is no living water.

All around was jungle, and a hazy fog began to appear in front of them.

Chen Xu's eyes narrowed, and he felt that something was wrong, so he immediately stopped.

Some viewers saw that Xu Ye was not leaving, and immediately sent a barrage to ask.

He pointed to the fog in front of him and said solemnly, "I don't know if you see the fog in the jungle ahead?"

The audience was a little puzzled:

"See, it's just ordinary fog!"

"yes, it doesn't seem like anything special. ”

"No, it's already past nine o'clock, and the weather is so sunny that there shouldn't be fog, right?"

Chen Xu nodded, "Someone still found something wrong, these fogs are not ordinary fogs, it is called jungle miasma, that is, poisonous fog, it is a toxic gas, the cause of miasma is the toxic gas emitted by the steaming of moisture after the decay of animals and plants." ”

According to the weather conditions of the past six years promulgated by the Meteorological Observatory, 85 percent of the weather here is cloudy or rainy, and only 10 percent are really sunny. ”

"In this environment, especially in spring, the wild grass rots, and it is easy to breed spring grass miasma, and once the human body inhales a large amount, it will immediately produce symptoms of chest tightness, dizziness, nausea and vomiting. ”

"Here, I will teach you a simple way to identify, that is, when we cross this terrain, if we find that there is no fog around the jungle, only in the jungle, it is basically certain that this is a poisonous miasma, and it is best to detour around it. ”

"If you have to cross, be sure to soak it with a towel or cotton cloth, cover your mouth and nose, filter the toxic gases, and in the process of crossing, you must bend down and keep yourself short, as little contact as possible with the fog suspended in the air, and quickly pass through dangerous places. ”

When some southern viewers heard this, they immediately sent a barrage to verify, saying that the forest near their home did have miasma.

"Nima, this Shennongjia is really dangerous, I didn't go because I listened to Xu Ye's words, otherwise I wouldn't know how to die!"

"666, someone like Xu Ye who doesn't bring anything, in case he encounters a miasma, he can only use his underwear as a mask, right?"

"Wow, wouldn't that be disgusting?"

"It's disgusting, it depends on whether you want to smell your underwear or you want to smell the miasma!"

Seeing this kind of barrage, Chen Xu could only cry and laugh.

Today's Shennongjia is a rare sunny day, so it is easy to tell if there is fog in the jungle.

Along the way, he walked in places with fresh air.

At noon, he heard a "bang" from the front.

Chen Xu's face was happy, knowing that he was not far from the water source.

Five minutes later, he saw a small river more than two meters wide.

"It's living water, and there are far fewer bacteria than dead water, but the possibility of parasites can't be ruled out, and I don't have a container at hand to boil the water. ”

"But we can still choose places where the water is fast, where the flow is fast and the chance of dust and parasites accumulating is minimal. ”

After explaining, Chen Xu picked a corner, lay on the ground, and drank two sips of water carefully.

Just as he was drinking water, a black shadow suddenly came out of the crack in the stone.

He was quick and grabbed the black shadow in his hand.

"Damn, so awesome, catching fish with your bare hands?"

"666, Xu Ye's hand speed, at least 20 years of singleness!"

"Impossible, right? How can a fish be so easy to catch?"

Chen Xu stretched out his hand.

Through the shooting of the camera, the audience saw that it was indeed not a fish, but a gecko-like creature, only a few centimeters in size, with a blue-black body, covered with slime.

"What is this, gecko?"

"How can a gecko be in the water, this should be a salamander, right?"

"It does look like an axolotl!"

Chen Xu smiled, "Everyone guessed half right, this is indeed similar to the salamander, but there is a separate classification, called the giant salamander, I name its other common name, you may have the impression that it is also called baby fish!"

Giant salamander?

Many viewers immediately felt that this title was familiar, but they couldn't remember the specific content at once.

"The salamander is the largest living amphibian in the world, and its adult can grow up to two meters, so it is called the salamander because its cry resembles the cry of a baby. ”

"It is widely distributed in China, because of its delicious taste, rich flesh, and natural mountain pepper flavor, so it has been hunted on a large scale, and now it has become an endangered animal and is protected by national laws. ”

As he spoke, Chen Xu put the baby fish in his hand back into the river.

"Oh my God, if this thing can grow to two meters, it would be too scary, right?"

"I can't help but think of the overlord salamander in "Exquisite Ancient City"!"

"Haha, Xu Ye's expression when he released the baby fish was particularly painful, obviously he wanted to eat it!"

"Doll fish: Thank you to the country and thank the party!"

After finding a water source, Chen Xu began to look for a location nearby and prepare to set up a campsite.

This is a typical river valley terrain.

It is hilly and mountainous on both sides, and in the middle is a depression through which the river passes.

"As I said before, Shennongjia is very humid and has a lot of rainy days, so when we choose to camp, we must avoid this low-lying river valley. ”

"On the one hand, it's to prevent the campsite from being flooded, and on the other hand, it's to avoid possible landslides, rolling rocks, and mudslides!"

Explaining the effort, Chen Xu found a mountain hole in the hills and mountains next to him.

The corners of his mouth curled, and he smiled, "It seems that I was lucky to find a natural hollow, which is stronger, safer, and windproof than ordinary shelters made of tree branches." ”

"The only regret is that the opening of this hole is too big, and I have to find a way to plug it, otherwise, not only will the warmth be poor, but also not very safe!"

While speaking, Chen Xu saw the gravel on the ground, "There are a lot of stones around here, maybe we can use it to build a stone wall, which will be a hundred times better than a fence built of tree branches!"

In contrast, some viewers immediately posted a barrage and said:

"Master Xu, you can't do this, right? These gravels are not bricks, they are big and small, and they are very irregular, how do you build stone walls?"

"Yes, even if Xie forcibly piles it up, I'm afraid it's not a wall, but a pile of stones, right?"

"Xu Ye should have his own way, right?"

Chen Xu looked at the barrage, nodded, and explained: "Everyone's doubts are actually very normal, it is indeed difficult to pile up a wall of these gravels, but if I use a tree trunk to tie a frame first, and then throw the stones into it to fill in." ”

"It's like when building a building, it is a reason to make a mold with wooden boards and steel bars, and then fill it with cement, so that the wall will be very stable!"
