Water, the most precious thing in the desert!

Especially in the case of water shortage, every drop of water is very precious, so even if it is your own urine, you can't waste it, because at a critical moment, it may be able to save someone's life.

Cheng Fei remembers that when he was learning survival skills in the wilderness, he once saw a news item on the Internet that a desert traveler had lost his way in the desert. After drinking all the fresh water that the man was carrying, he survived the arrival of the search and rescue team by drinking his own urine.

Therefore, although he was very reluctant, if it really reached the point of exhaustion, Cheng Fei could only choose to drink his own urine, after all, he didn't want to die.

However, having said that, drinking urine is also very particular.

Because, although urine is basically composed of water, it also contains various impurities and toxins in the human body, so it is best not to drink urine directly unless it is a matter of life and death.

If it really comes to a critical moment and you have to drink your own urine to save your life, then it is best to take the urine in the middle section to drink, because, according to medical theory, the urine in the middle section is non-toxic and sterile, and even in special cases, the urine in the middle section can be used to clean the wound.

And, one thing to keep in mind: the urine you drink should not be left on for too long, but only before the urine has completely cooled down and started to turn yellow.

Belch......... The reason why I say so much is just to tell you a truth, that is: urine is not what you want to drink, you can drink it if you want to.........

At this time, the method adopted by Cheng Fei is the filtration water method.

He wrapped the sand in the vest to make a simple filter, and the urine was filtered through the double layer of sand and vest, which could greatly reduce the impurities and toxins contained in it, at least, it was much safer than drinking urine directly.

Passing through the door of adventure and spanning two worlds, Cheng Fei's soaked urine has at least five hundred milliliters, and after filtration and loss, there are still three or four hundred milliliters left.

Shaking the kettle and listening to the sound, Cheng Fei couldn't help but have a bitter smile on his face: This ........ It is the back hand he has prepared for himself.

Hopefully, never need it!

With a sigh, Cheng Fei spread his vest on the edge of the sand pit, and he went back to the sand pit to lie down, he wanted to sleep, but the temperature was too high, and there was neither an electric fan nor an air conditioner here, so he couldn't fall asleep anyway, so he had no choice but to silently carry the meditation method of Baguazhang, close his eyes and recuperate.

Enduring the scorching heat, time seemed to slow down, and Cheng Fei felt as if he had entered an endless realm of cultivation, obviously it was only two or three hours, but it seemed like two or three centuries had passed.

Finally survived the high temperature during the day, Cheng Fei climbed out of the sand pit.

As a person who practices martial arts, his six senses are sensitive, far beyond ordinary people, so he can clearly feel that the sunlight at this time is not as strong as at noon, and the temperature has also decreased.

That's great news!

Cheng Fei sorted out his clothes and belongings, kettles, flints, treasure maps and dog-leg knives, although the vest had been dried, there was a smell of urine, but in this case, he could only use his strength.

As before, with the vest covered over his face, leaving only a thin slit at his eyes, Cheng Fei embarked on the journey again.

The vast desert, boundless, the hot wind blows from time to time, raising the sky and flying sand, Cheng Fei walks in it, feeling like walking in the sand rain.

As far as the eye can see, there is rolling yellow sand all around, and there is no end in sight.

The sky is high and the earth is infinitely vast, which is indeed the most spectacular scene of nature, but at the same time, it is also the most desperate environment, and it is easy to make people despair.

Mindset is especially important at times like these.

Even in despair, adventurers must hold the belief that "I will succeed", otherwise, once people fall into despair and extreme pessimism, they will lose their minds, act irrationally, and even send themselves to a dead end.

Fortunately, although Cheng Fei is not a naturally optimistic person, he does not have much pessimism, and in the process of moving forward, he is not idle, but thinking about cultivation, first, he hopes that he can integrate cultivation into his life, and secondly, he can also distract his attention, so that he does not keep focusing on despair.

Although he has not been in contact with martial arts cultivation for a long time, Cheng Fei has the complete inheritance of Baguazhang and is very clear about every step of his cultivation, so after a period of research, he gradually has some clues.

Breathing, pace, and strength, just as Cheng Fei's research was rising, suddenly, a bright green in the distance came into his eyes.

Suddenly awakened, Cheng Fei stared at it, and it turned out that it was actually a huge columnar cactus, standing on the desert, even if the wind and sand were thousands of miles, it was difficult to break.

This is the largest plant Cheng Fei has seen since he came to the Great Desert of the Western Regions, and it is also the most beautiful plant in his eyes!

Without the slightest hesitation, Cheng Fei immediately headed towards the giant cactus, and when he got closer, he found that the giant cactus was far bigger than he had imagined.

At a height of seven or eight meters, it is as majestic as an ancient giant!

"What a big cactus!"

Cheng Fei couldn't help but exclaim, and at the same time, a little smile couldn't help but appear on his face.

Since entering the desert, he has been suffering from a lack of water, and even has to collect his own urine, and now, he can finally breathe a sigh of relief.

Although the cactus is covered with spikes, it is known as the "sweet spring of the desert" because it is an extremely drought-tolerant plant, and its stems contain a lot of water and sugar, so that desert travelers in distress can split large cacti and dig up their tender and juicy stems to quench their thirst.

Cactus meat has the effect of lowering blood sugar, lowering blood lipids and blood pressure, if you can eat a vegetable cactus every day, you can eliminate excess cholesterol, fat and sugar in the body, play a role in qi, blood activation, heat clearing and detoxification, promote metabolism, and even, can also be used for weight loss.

Although not all cacti can be eaten, at least, Cheng Fei knows that the one in front of him is still edible, and it is not in vain to study with Sun Tu, a wilderness survival expert, for nearly a month.

With such a large cactus, Cheng Fei naturally couldn't eat it all, he only needed to pick a fork, which would not endanger the life of the cactus.

He was a little selective, chose a thicker fork, and chopped it down with a dogleg knife, peeling off the spikes and skin on it, revealing the green and white and tender stem meat inside, which was very appetizing to look at, but in fact, the taste of cactus meat was not very good, and there was a trace of bitterness in the thick and clear air. However, the juice was quite full, and he endured the bitterness, and took a few large bites, feeling less thirsty than before.

There is no way, survival is like this, in order to survive, you must learn to endure, only by overcoming all difficulties and obstacles, and getting out of the predicament alive, can you be regarded as a qualified adventurer.

"It's like eating melon!"

Cheng Fei comforted himself so much, although this can't change anything, at least psychologically better. At that moment, there was a slight sound that pierced his ears.

"Huh?"

Cheng Fei almost subconsciously looked towards the source of the sound, only to see that under the surface of the sand not far away, a small thing was moving rapidly.........
