30 days of wilderness survival

Water is the source of life.

People cannot be short of water, especially in a hot environment, an adult needs at least three to five liters of water to maintain the normal metabolism of the human body.

Coconut water has a good cooling effect, quenching thirst, and also has a diuretic effect, but coconut water is cold, should not be drunk excessively, excessive drinking will lead to gastrointestinal discomfort, which will lead to diarrhea.

Although Qin Feng's body had been strengthened, it was far better than that of ordinary people, but even so, without sufficient water intake, it was difficult for him to maintain his state at the peak.

The rainforest hides countless dangers, poisonous insects and beasts, each of which has the potential to pose a deadly threat, and he must keep himself in peak condition so that he can deal with the danger that may come at any time.

Tropical rainforest, lush vegetation, water source must be very abundant, and what Qin Feng needs to do is to find a water source.

Just finding the river hidden in the jungle can solve not only the problem of drinking water, but even the problem of food.

Where there is a river, there must be fish, and in a place like this that has not been set foot by humans, the fish in the river must be very abundant, and there is no human catch, and there will definitely be no shortage of fish over the years.

It's much easier to catch a fish in a river than a fish in the sea.

In addition, even if there is no fish, there will definitely be other catches.

If the animals in the tropical rainforest want to survive, they also need to drink water, and the water from food is far from satisfying their needs for growth and reproduction.

Seeing that it would be dark in less than three hours, Qin Feng decided to hurry up and investigate, and if he couldn't find it today, he would look for it tomorrow, anyway, he had time.

Under the gaze of Xiao Zhan and the four of them, Qin Feng climbed up a big tree and began to observe the topography of the island.

And the reason why he wants to do this is naturally his reason, people go to high places, water flows to low places, rivers flow from high places to low places, and the same is true for rivers in tropical rainforests.

Lost in the rainforest, there is hope that if you can tell the difference between high and low terrain, you can hope to find a water source.

Trees cannot grow without sunlight and water, and those trees near rivers grow much faster than their counterparts elsewhere due to their abundance of water.

As a result, the trees that grow near the river are much taller than those in other places, and if you look closely, you can tell the difference between them and the surrounding trees.

After looking around for a while, Qin Feng finally found a signal from the water source, but unfortunately, it was far from where he was.

"Damn, it's too far, at least five hours!"

Qin Feng couldn't help but be a little disappointed, this was too far from what he expected, the river was hidden in the deepest part of the jungle.

Tropical rainforests are one of the most dangerous places on earth, and the deepest part of the rainforest is the most dangerous place for rainforests.

As far as the eye can see, there is only one river, and this means that all the animals in the jungle will go there to drink, and humans, as intruders, will inevitably be attacked by them.

"Alas, it looks like we can only plan tomorrow!"

Qin Feng couldn't help but sigh and climbed down the tree, and just as he landed, a white tree root attracted his attention.

"Is this cassava?!"

With a skeptical attitude, Qin Feng bent down and stretched out his hand, tugging at the white tree root.

This drag directly dragged out the big guy buried in the soil.

Just as Qin Feng thought, the white root on the ground was none other than the rhizome of cassava.

"Hey, is this a sweet potato?"

At this moment, Xiao Zhan greeted him and looked at the things in Qin Feng's hand and looked at them.

Zhao Liying said excitedly: "Isn't this a sweet potato! I didn't expect to find sweet potatoes in this kind of place!"

"I like roasted sweet potatoes the most, it tastes so good!"

As Di Lieba spoke, he stretched out his hand towards the "sweet potato" in Qin Feng's hand.

At the same time, the audience watching the live broadcast was also talking.

"Is this really a sweet potato?"

"Why doesn't I feel like it?"

"I just took a look at the sweet potatoes at home, and it's a lot worse than this!"

"This shouldn't be a sweet potato, it's cassava!"

"Cassava?!What the hell is that!"

Qin Feng shook his head, cleared his throat, and introduced: "Don't look at this plant as a sweet potato, but it is not a sweet potato, but cassava, which is mainly distributed in the tropics. "

"Cassava is native to the Americas, and has fleshy long cylindrical roots, which are rich in starch and can be eaten or used as paste, which can be ground in cassava flour and made into bread, but it is different from sweet potatoes, it cannot be eaten raw, and it must be soaked in water for a long time and cooked to remove toxicity. "

"Cassava contains a toxic substance called linolenic bitter glycoside, which can be poisoned if raw or undercooked cassava is ingested or its soup is consumed. If a person eats 150-300 grams of raw cassava, it can cause poisoning and even death!"

"To prevent cassava poisoning, before eating cassava, the skin must be removed, and then the potato flesh must be soaked in water to dissolve the toxic substance, and it is generally soaked for about six days to remove 70 percent of the toxin, and then heated and cooked so that it can be eaten. "

After introducing cassava, Qin Feng threw the cassava in his hand violently, then took a bottle of seawater and washed it away, washing away the sticky mucus on his hands.

"Alas, I thought it was delicious, but I didn't expect it to be poisonous!"

Di Lieba sighed helplessly, but at the same time, she felt lucky, fortunately Qin Feng knew more, otherwise if she found out, she would definitely take it and throw it into the bonfire to roast and eat, and she would definitely be poisoned by then.

Qin Feng said: "The main thing is that it's too troublesome to soak for six days, just to eat a cassava for six days, and we don't have so much time to waste." "

Xiao Zhan nodded and said, "That's right, I'm afraid that after soaking for six days, there will be poison, and then the gains will outweigh the losses, so there is no need to do this." "_
