On the hot sand dune, Bi Fang lay on his back, his chest rising and falling violently.
Now his back is still aching.
It’s really dangerous!
Fortunately, I opened the umbrella at 350 meters this time, otherwise I would have really stopped!
But Bi Fang was not afraid. He was already mentally prepared for an accident. What kind of adventure would it be if there was no accident?
The sky is filled with wind and sand.
Bi Fang lay on the ground for three minutes, when suddenly a gust of wind and sand blew in, choking him.
"vomit!"
"Poof!"
Bi Fang sat up suddenly, coughed twice, and spit out the sand in his mouth.
【Alive again!】
【full HP resurrection!】
[The clothes are of decent quality, not torn at all.]
【Professional equipment, are you kidding?】
【Fang Shen yyds!】
"What the hell? Are you cursing me to be single forever? I'm a straight man. No matter how much you curse me to find a girlfriend, you still won't get my person." Bifang spat out the sand in his mouth and made a joke.
.
He knew it was the God of Eternity, but every time he saw it, he felt like it was cursing him to be single forever.
After resting, Bi Fang stood up and took off all his goggles and parachute bag. These were not system equipment and could not be carried, and they were too heavy. In the desert terrain, any load must be carefully calculated.
"I don't know how to use these equipment. After all, a parachute can be used in too many places, so I threw them all here. The big brother who flies the helicopter will come down and collect them later."
[Another small detail to protect the environment]
[Positive energy, iron juice]
[Wearing professional outdoor sportswear: I don’t know how to use an umbrella bag, it has too many uses (funny)]
[I feel like it’s more difficult to survive this time, in the desert, there’s nothing but sand.]
[Stop talking, I’m already thirsty]
The drone that had been falling freely with Bifang had long been suspended. At this moment, it took off and captured an unobstructed view of the Qaidam Desert.
Like Mohe, the colors are extremely monotonous when you look at them. However, one is covered with white snow, and the other is filled with yellow sand.
Dry ancient sand winds swept across the desert, exposing huge earthy rocks on the ground.
The red Gobi desert and the dull yellow-green color are completely different from the colors of this world.
This place has been like this for thousands of years, flat, vast, dry, desolate, silent, desolate...
Never changed.
In the distance, the distorted heat waves are visible to the naked eye, declaring the passion of this land.
Having just landed from a cold altitude, Bifang didn't feel the heat yet. He looked up at the sky and took off his jacket and inner lining.
Different from the past, this time Bifang did not give priority to identifying the direction. Instead, he came to the shadow of the boulder and sat down.
Under the broken rock, a black and shiny scorpion was swinging its poisonous hook, and was cautiously approaching the small insect in the haystack. Suddenly, it was suddenly alarmed by this giant creature, and quickly slipped into the rock crevice and escaped.
【???】
[Why are you still sitting down? Are you not going to survive? 】
[Why do you feel that the style of painting is different this time? 】
【You have changed, Fang Shen!】
"Why are you so anxious?" Bi Fang was very leisurely. He raised his head and looked into the distance, pointed at the sun in a leisurely manner and said, "Just look at the sun, does it look like it can hurry up?"
The drone raised its lens, and the dazzling sunlight suddenly made the audience squint.
Huo, what a big sun!
"Making survival plans based on different environments is the key to survival. Deserts are different from forests and snow forests. Here, daytime is not a good time to travel. We should choose to travel in the evening and early morning."
"The cooler night air allows you to travel faster with minimal risk of heat stroke. In hot climates, this single decision will save your body three liters of water per day."
"In the desert, survival is no longer our top priority, because escaping to heaven will not be a short-term mission. What is more important for us is to find the source of life, water!"
【Are you going to sit here all the time?】
【A bit boring】
Many viewers were confused. Although skydiving just now was very exciting, they couldn't just stop and stop.
"Of course not. It's only ten o'clock in the morning. The traveling time we should avoid is between eleven and four o'clock in the afternoon. I'm here to make some preparations!"
In the desert, the most dangerous enemy is undoubtedly temperature.
It can lead to dehydration, heat stroke, and a series of serious problems, especially water shortage. If you are dehydrated in the desert, your whole body will be dried out in the sun within a few days!
"Most of our body's water loss occurs through sweat. Cover as much skin as possible with loose, lightweight clothing. This will cause your skin to sweat and slow evaporation, thus reducing water loss."
"For this reason, it's better to wear a cotton undershirt rather than a wicking fabric and then cover it with a light windbreaker, and color wise..."
Before Bi Fang could finish speaking, he was interrupted by a barrage on the screen.
[I know this, you have to wear light-colored clothes, right?]
[Isn’t this nonsense? Light-colored reflective, not hot!]
[Why do I remember that people in the desert wear black clothes?]
[Did you remember correctly upstairs? Arabs all wear white!]
"Everyone is right." Bi Fang was speechless when he saw the quarrel in the barrage. Why couldn't you just listen to what he had to say?
"Actually, what I want to say is, if you don't have professional equipment, it doesn't matter what color it is!"
How can it be?
Not only the audience, but also Yao Jun, who has always liked outdoor sports, was also confused.
How could it not matter?
Aren't those Arabs all wearing white robes? If they are all the same, why don't they wear black?
And black absorbs heat. Isn’t this basic physics?
Faced with this question, Bi Fang actually nodded directly: "Who says there is no such thing? In fact, if you observe more carefully, you will find that the residents of the Sinai Desert are wearing black robes!"
"This was the subject of an academic study in the journal Nature in 1980. The title of the study was 'Why do Bedouins wear black robes in the hot desert?'"
"After research, they found that the difference between the two is basically 0!"
Ah this.
The noisy water friends all stopped in silence. Many of the audience were old friends. They had no doubt about Bi Fang's knowledge. After hearing this conclusion, they actually believed most of it.
It turns out that they had been arguing for a long time, but it turned out to be meaningless?
Bi Fang paused for a moment, then continued after seeing that everyone stopped arguing.
"Studies have found that black clothing does absorb more heat, but the heat stops there."
"In other words, the black clothing absorbs extra heat, but by the time it actually touches the skin, that extra heat has disappeared because the robe is large and easy to flip, allowing air to flow, and the heat has dissipated."
"Of course, there is also the argument that the 'light clothing' theory misses a key factor."
Bi Fang raised a finger and said mysteriously: "The heat radiated by the human body!"
"They believe that the heat radiated by the body will also be reflected by light-colored clothes and return to your body again, making you feel hotter. I think this theory is good, but it has not been tested on people, and I don't know whether it is true or not."
"But for the headgear, my suggestion is still white, because the headgear fits tightly to the head and does not have gaps like clothes, which facilitates air circulation and heat will really accumulate."
"In addition, if possible, find white clothing marked with UPF, which is an ultraviolet protection factor of 30+ or above! This will make you less likely to get sunburned."
After finishing speaking, Bi Fang took out a thin windbreaker from his bag and put it on. Finally, he took out a cotton short-sleeved shirt and also covered his face.
He stood up, looked into the distance, judged the direction, and was about to set off. Suddenly, a strange noise that did not sound like wind suddenly appeared, attracting everyone's attention.
