At noon, the sun shines brightest during the day.

Coupled with the fact that it is located below the equator, ultraviolet rays can sunburn people in just one hour.

At this moment, Ye Xuan walked out of the shade of the tree, and the scorching sunlight suddenly enveloped him, which made people feel very uncomfortable.

There are many shells scattered on the beach, some washed up by the waves, and some picked up by seabirds.

In a short time, he collected more than a dozen shells. These shells vary in size, the largest being more than 30 centimeters in diameter, like a small washbasin.

So many shells are enough, he doesn't have many bottles to store water now, and it's useless to collect too many shells, and when the time comes, he can only watch the rain evaporate.

Thinking of this, Ye Xuan hugged the shell and walked quickly towards the camp.

A dozen shells, neatly stacked by him, on the beach in front of the camp, would be filled with rainwater if the rainstorm hit.

"I can't put all my freshwater hopes on rain, and if it doesn't rain in the next few days, it's like a slow death. Ye Xuan took out a waterproof bag from his backpack and said, "So, I will use all means to collect fresh water." ”

As he spoke, he removed the dagger from his leg and cut it all along the edge of the bag.

This waterproof bag is quite large, and he used it to hold drones, but now that he is in a difficult situation, he can't manage these things. When the waterproof bag is cut, it becomes two transparent plastic sheets with a length and width of 40 cm.

"I'm going to use solar distillation to collect fresh water. ”

Holding two pieces of plastic film, Ye Xuan walked out of the shade again, squatting on the beach, and digging the sand with both hands.

As a result, after digging a few times, Ye Xuan shook his hand and stopped, frowning: "No, the sand is too hot." ”

The specific heat capacity of the sand is very low, so the heat absorption rate is very fast, and the high temperature of 36 degrees Celsius makes the sand on the surface of the beach hot. Fingers digging into it like touching a red-hot soldering iron.

When he came to a pile of shells, he picked a palm-sized shell, returned to his position, and continued to squat on the beach, grabbing the shells with both hands like a marmot, and digging up quickly.

For a moment, the sand flew.

"I believe that most of the audience already know what I am going to do. The principle of distillation is very simple, you only need to dig a sand pit, then fill it with seawater, and finally cover it with plastic film. The high temperature and scorching sunlight cause the seawater in the bunker to quickly evaporate into water vapor, which eventually condenses on the surface of the plastic film. ”

Wiping the sweat on his forehead, Ye Xuan's hands kept moving, and he continued: "This method is best used in a hot environment, if it is other low-temperature environments, I recommend not using this method, because the fresh water obtained is far inferior to the water consumed." ”

In fact, this method can also be used in the desert, although there is no seawater in the desert, but it can be replaced by urine and plants. However, solar distillation takes too long, and it is estimated that the survivors have already dehydrated before the fresh water has evaporated. So Ye Xuan didn't use this method at the beginning, but drank urine directly and ate raw reeds.

"The temperature here is very high and the sea is abundant, so I estimate that I can collect about 1L of fresh water in a whole day. Now there are two plastic films, which means that I can collect 2L of fresh water a day, and the key distillation water is very stable, except for rainy weather, it can provide me with fresh water every day. ”

2L of fresh water per day means that the remaining 8 coconuts can be saved and left for drinking after going to sea. As for plastic bottles and kettles, they can also be filled with water.

The sand was very soft, and in about half an hour, he dug two 30-centimeter-square bunkers. In fact, if he could, he would like to dig bigger, because the bigger the bunker, the more fresh water will be collected through evaporation, but the plastic film is only that big.

The drone is suspended in mid-air, and through the aerial angle, two square bunkers next to each other are like a pair of glasses.

Seeing this scene, the audience in the live broadcast room began to launch a barrage.

"Black-rimmed glasses? long... Elders!"

"A true fan, even if..."

“-1S！”

“*******。 ”

"Get out, you don't deserve to read his poems!"

"Open the door, check... Forget it, the demolition team will go straight to it!"

"Good boy, you guys have something, can this be filmed?"

"This is a broken live broadcast room to eat jujube pills. ”

Glancing at the barrage, Ye Xuan's face was suddenly full of black lines, and he hurriedly spoke: ", don't make trouble, you will be blocked in the live broadcast room!"

He was a little speechless, these spectators can even film the bunker, it's just terrifying.

After digging the sand pit, Ye Xuan took out a shell again, this shell was quite large, enough to hold 1L of water.

They take their shells to the beach, fill them with seawater, and pour them all into a sand pit, where they gradually evaporate into completely distilled water in the scorching heat.

Then, he placed the shells in the center of the bunker, and after placing the shells, he covered the bunker with plastic film, and the surrounding area was firmly covered with sand. Then he grabbed a handful of sand and pressed it in the center, causing the whole plastic film to sink towards the center.

Patting the sand on his hands, Ye Xuan explained with a smile: "The purpose of this is to let the water droplets condensed on the surface of the plastic film converge towards the central depression, and then accurately slide into the shell. ”

After solving a beach, he did the same and got another bunker. Over the next few days, these two bunkers will provide him with a steady stream of fresh water.

After doing it, he smiled at the live camera: "Okay, wait until evening, you can come and get water." This method is simple, requires no skill and saves time and effort, as long as you add seawater to the bunker once a day. ”

Returning to the grass shed and sitting down, Ye Xuan was a little confused for a while.

The original plan was to stay on the island for three days, and if rescue did not come, go to sea to save himself. It's only been a day and a half, and everything that needs to be done has been done, and it seems that now is quietly waiting for help to arrive. But the sudden idleness in the middle of a dangerous wilderness made him very uncomfortable.

Glancing at the barrage, Ye Xuan spoke: "When waiting for rescue, my mentality will always be uneasy. Because you never know when help will come, and even if it does, it's unknown whether it will be found or not. At this time, you need to do something to relieve your potential tension. As I said on a previous show, don't waste too much time looking for food in the wilderness. But right now, what I have the most is precisely time. ”

"If I sit here and wait for the past two days, my anxiety will gradually affect me. Especially as time goes on, help doesn't come and despair grows in your heart. So, I had to do something to try not to think about the rescue. ”

Speaking of this, he stood up, looked at the blue sea and golden sand in front of him, and said with a smile: "Food can soothe people's minds, so I decided to go fishing and see if I could catch some delicious food." ”
