Live Wilderness Adventure

Chapter 104 Black or White? (ask for the first order!)

On the hot sand dunes, Bi Fang was facing the sky, his chest heaving violently.

Now his back is still aching.

It's really dangerous!

Fortunately, the parachute was opened at 350 meters this time, otherwise it would be really hard!

But Bi Fang wasn't afraid, he was already mentally prepared for an accident, so what kind of adventure would there be without an accident?

The wind and sand filled the sky.

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

"vomit!"

"Pfft!"

Bi Fang sat up suddenly, coughed twice, and spit out the sand in his mouth.

[It's alive again! 】

【full HP resurrection! 】

[The clothes are of good quality, not torn at all. 】

[Professional equipment, are you kidding? 】

【Fang Shen yyds!】

"What the hell? Curse me to be single forever? I'm a straight man of steel. No matter how hard you curse me, I won't find a girlfriend, and I won't get my man." Bi Fang 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 he was being cursed to be single forever.

After resting, Bi Fang got up and took off all the goggles and umbrella bag. These are not system equipment and cannot be carried, and they are too heavy. In the desert terrain, any weight must be calculated carefully.

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

[I feel that survival is more difficult this time, the desert is sand, besides sand. 】

【Stop talking, I'm already thirsty】

The UAV that fell freely along with Bi Fang had been suspended for a long time, and now it took off to take a panoramic view of the Qaidam Desert.

Like Mohe, looking around, the colors are extremely monotonous, but one is plain white snow, and the other is full of yellow sand.

The dry and ancient sandstorm swept across the desert, and the earth-yellow boulders were exposed on the ground.

The crimson Gobi and the dull yellow-green are already quite different from the colors of this world.

This has been the case here for thousands of years, flat, vast, arid, desolate, silent, barren...

never changed.

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

Having just landed from the cold high altitude, Bi Fang didn't feel the heat yet. He looked up at the sky and took off his jacket and inner lining.

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

Under the broken rock, a shiny black scorpion was shaking its poisonous hook, and was cautiously approaching the bug in the haystack. Suddenly, it was startled by this huge creature, and quickly slipped into the crevice of the rock to escape.

[? ? ? 】

[Why are you still sitting down? Not to survive? 】

[Why do you feel that the painting style is different this time? 】

【You have changed, Fang Shen! 】

"What's the rush?" Bi Fang was rather leisurely. He raised his head and looked into the distance, pointing at the sun and said, "Just look at the sun, does it seem like you can drive?"

The drone raised the camera, and the dazzling sunlight made the audience squint their eyes.

Huo, what a big sun!

"Making a survival plan according to 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."

"Cooler air at night allows you to travel faster with minimal risk of heat stroke. In hot climates, this decision alone will save your body three liters of water a day."

"In the desert, survival is no longer our top priority, because it will not be a short-term task to escape and ascend to heaven. What is more important for us is to find the source of life, water!"

[Then sit here all the time? 】

【A bit boring】

Many spectators were dumbfounded. Although skydiving was very exciting just now, they couldn't stay still right after they came out.

"Of course not. It's only ten o'clock in the morning. The rush time we should avoid is between eleven o'clock 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 will 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 up in the sun!

"Most of the water loss from our bodies happens through sweat. Cover as much of your skin as possible with loose, lightweight clothing. This will cause your skin to sweat and slow evaporation, which reduces water loss."

"For this reason, we'd be better off wearing a cotton undershirt than a wicking fabric, and covering it with a light trench coat, and color-wise..."

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

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

【Is not this nonsensical? Light color reflective, not hot! 】

[How do I remember that people in the desert wear black clothes? 】

[I remember wrong upstairs? All Arabs wear white! 】

"Everyone is right." Bi Fang was a little speechless when he saw the quarrel in the barrage, why couldn't he finish what he had to say?

"Actually, what I want 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 dumbfounded.

How could it not matter?

Aren't those Arabs all in white robes? If they are all the same, why not wear black?

And black absorbs heat, isn't this basic physics?

Faced with this question, Bi Fang nodded directly: "Who said there is no, 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 titled 'Why do Bedouins wear black robes in the hot desert?'"

"As a result, after research, they found that the difference between the two is basically 0!"

Ah this.

The water friends who were arguing so loudly froze together. Many of the audience were old friends, and they had no doubts about Bi Fang's knowledge. Hearing this conclusion, they were actually more than half convinced.

It turned out that they had been arguing for a long time, but it turned out to be meaningless?

Bi Fang paused, seeing that everyone stopped arguing, and continued.

"The study found that black clothing did absorb more heat, but the heat stopped 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 wide and easy to flip for air flow, and that heat has been dissipated."

"Of course, there is also an argument that the 'light clothing' theory ignores a key factor."

Bi Fang held up a finger, pretending to be mysterious: "The heat radiated by the human body!"

"They believe that the heat radiated from the body will also be reflected by light-colored clothing and return to you, making you feel hotter. I think this theory is good, but it has not been tested on humans, and I don't know if it is true or not."

"However, for the headgear, my suggestion is white, because the headgear is close to the head, and there is no gap like clothes, which is convenient for air circulation, and the heat will really gather."

"Also, if possible, find white clothing marked with UPF, that is, ultraviolet protection factor, above 30+! It is not easy to get sunburned."

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

He stood up, looked into the distance, judged the direction, and was about to set off. Suddenly, a strange sound that didn't sound like the wind suddenly appeared, attracting everyone's attention.

This is

The sound of the engine?

Wait, a car engine?

Who would drive in the desert?

Did I meet someone so quickly?

Bi Fang was a little confused.

He has only just begun to survive!

The first three chapters, come on, brothers!
