On the hot sand dunes, Bi Fang faced the sky on his back, his chest rising and falling violently.

His back still ached.

It's really dangerous!

Fortunately, this time it was at 350 meters, otherwise it would have been a real break!

However, Bi Fang was not afraid, he was already mentally prepared for an accident, what kind of adventure was it if there was no accident?

The sky is full of wind and sand.

Bi Fang lay on the ground for three minutes, when suddenly a gust of wind and sand blew and choked him.

"Gross!"

"Poof!"

Bi Fang sat up suddenly, coughed twice, and spat out the sand from his mouth.

[It's alive again!] 】

[Full Blood Resurrection!] 】

[The quality of this dress is good enough, it's not broken at all. 】

[Professional equipment, joking? ] 】

【Fang Shen YYDS!】

"What's that? Curse me to be single forever? I'm a straight man of steel, no matter how much you curse me for not finding a girlfriend, you won't be able to get my person. Bi Fang spat out the sand in his mouth and made a joke.

He knew it was an eternal drop god, but every time he saw it, it felt like he was cursed to be single forever.

After resting, Bi Fang got up and took off all the goggles and umbrella bags, these are not system equipment, they can't be carried, and they are too heavy, in the desert terrain, any bit of weight must be carefully calculated.

"I won't use these equipment, after all, there are too many places where a parachute can be used, so I will throw them all here, and the big brother who drives the helicopter will come down and take them away."

[Another small detail to protect the environment]

【Positive Energy Oh Iron Juice】

[Wearing professional outdoor sportswear: I won't use the umbrella bag, it has too much effect (funny)]

[I feel that it is more difficult to survive this time, desert, except for sand or sand.] 】

[Don't say it, I'm already thirsty]

The drone that fell freely with Bi Fang had long been suspended, and it rose into the air at this moment, taking a panoramic view of the scene of the Qaidam Desert.

Like Mohe, as far as the eye can see, the color is extremely monotonous, but one is plain white snow, and the other is full of yellow sand.

Dry, ancient sand winds swept across the desert, and earthy yellow boulders were exposed to the ground.

The red Gobi and the yellow-green dryness are already very different from the colors of this world.

It has been like this for thousands of years, flat, vast, arid, desolate, silent, barren......

It hasn't changed.

In the distance, a distorted heat wave is visible to the naked eye, proclaiming the enthusiasm of the land.

As soon as he landed from a cold altitude, Bi Fang didn't feel the heat at this moment, he looked up at the sky, took off his jacket and underwear.

Unlike in the past, this time Bi Fang did not give priority to discerning the direction, but came to the shadow of the boulder and sat down.

Under the broken rock, the black and shiny scorpion shook its poisonous hook, and was cautiously approaching the small insect in the grass, when it was suddenly startled by this behemoth, and quickly slipped into the rock crevice to escape.

【？？？ 】

[Why are you still sitting down?] Don't go to survive? 】

[How do you feel that the style of painting is different this time?] 】

[You have changed, Fang Shen! 】

"What's the hurry?" Bi Fang was very leisurely, he looked up into the distance, and pointed to the sun without hurrying, "You just look at this sun, as if you can hurry?" ”

The drone lifted the camera, and the dazzling sunlight suddenly made the audience squint.

Ho, what a big sun!

"Survival planning according to different environments is the key to survival, deserts are different from forests and snowy forests, where daytime is not a good time to rush, we should choose to rush in the evening and early morning."

"The cool air at night allows you to travel more quickly and there is very little risk of heat stroke. In hot climates, this single decision will allow your body to save three litres of water per day. ”

"In the desert, survival is no longer our top priority, because if we want to escape from the ascension, it will not be a short-term task, but more importantly, we will find the source of life, water!"

[Then sit here all the time?] 】

[It's a little boring]

Many viewers were stunned, although the skydive just now was very exciting, but they couldn't just come out and not move.

"Of course not, it's only ten o'clock in the morning, and the rush time we should avoid is between eleven and four o'clock in the afternoon, and I'm here to make some preparations!"

In the desert, the most dangerous enemy is undoubtedly temperature.

It can lead to water shortage, heat stroke, and a series of serious problems, especially water shortage, if you are dehydrated in the desert, within a few days, the whole person will be dried out!

"Most of the water loss in our bodies occurs through sweat. Cover as much skin as possible with loose, lightweight clothing. This will make your skin sweat and slow down evaporation, which will reduce water loss. ”

"For this reason, it's better for us to wear a cotton undershirt instead of a sweat-wicking fabric and cover it with a light trench coat that ...... in terms of color"

Before Bi Fang could finish speaking, he was interrupted by a barrage on the screen.

[I know this, I have to wear light-colored clothes, right? 】

[Isn't this nonsense?] Light-colored reflections, not hot! 】

[How do I remember that it seems that people in the desert wear black?] 】

[Upstairs misremembered, right?] Arabs wear white! 】

"Everybody's right." Bi Fang saw that there was a lot of noise in the barrage, and he was a little speechless, why couldn't he listen to him finish speaking?

"Actually, what I'm trying to say is that if you don't have professional equipment, it doesn't matter what color you are!"

How can it be?

Not only the audience, but even Yao Jun, who has always liked outdoor sports, was also stunned.

How can it not matter?

Aren't all those Arabs dressed in white robes? If it's all the same, why not wear black?

And black is endothermic, isn't this fundamental physics?

Faced with this kind of question, Bi Fang nodded directly: "Who said no, in fact, if you observe more carefully, you will find that the inhabitants of the Sinai Desert are wearing black robes!" ”

"In 1980, in an academic study in the journal Nature, the topic was 'Why do Bedouins wear black robes in the hot desert?' ”

"As a result, after the study, they found that the difference between the two was basically zero!"

Ahh

The noisy sailors were all stunned, many of the audience were old friends, and they had no doubt about Bi Fang's knowledge, and when they heard this conclusion, they actually believed most of them in their hearts.

It turns out that they quarreled for a long time, and the result was meaningless?

Bi Fang paused, saw that everyone was no longer noisy, and continued.

"The study found that the black clothes did absorb more heat, but the heat stopped."

"In other words, the black garment absorbs the extra heat, but by the time it actually touches the skin, that extra heat is gone, because the robe is wide and easy to turn over for air to flow, and the heat has already dissipated."

Of course, there's also the argument that the "light-colored clothing" theory ignores a key factor. ”

Bi Fang raised a finger and pretended to be mysterious: "The heat radiated by the human body!" ”

"They believe that the heat radiated from your body is also reflected by light-colored clothing and comes back to you again, making you feel hotter. I think this theory is good, but I haven't tested it in people, and I don't know if it's true or not. ”

"However, for the head covering, my advice is white, because the head cover is close to the head, unlike the clothes, there is a gap, which is easy for air circulation, and the heat will really build."

"If possible, look for white garments marked with UPF, which is the UV Protection Factor, and are above 30+! This makes it less likely to get sunburned. ”

After speaking, Bi Fang took out a thin windbreaker from his bag, put it on his body, and finally took out a cotton short-sleeved shirt, which was also covered on his face.

He stood up, looked into the distance, judged the direction, and was about to set off, when suddenly, a strange sound that did not resemble the sound of the wind suddenly appeared, attracting everyone's attention.

This is......

The sound of the engine?

Wait, car engines?

Who will drive in the desert?

Did I meet someone so quickly?

Bi Fang was a little confused.

He's just starting to survive!
