Whether it's jungle survival training or desert survival training, the first thing to consider is the water source. Rainwater can be used as one of the most important ways to obtain water anywhere, but in desert arid areas, the most obvious environmental feature is extremely scarce rainfall. And due to the arid nature of the desert, the rain that falls quickly seeps below the ground.

So instead of holding a container and praying for God's favor in the desert area for a heavy rainstorm, it is far better to find a way to obtain water by yourself.

In addition to finding edible plants that grow in the desert, the quickest and easiest way to obtain water in the desert is to condense the water stored in the sand layer by means of thermal distillation.

Dig your hand deep into the sand, feel the humidity of the sand layer through your skin, choose a place with high humidity, and dig a hole. A plastic film is placed on the entrance of the hole, and the sun is pressed with a heavy object to extract moisture from the ground, and crystals form on the plastic film, which finally fall into a container placed under the plastic film and gather.

This kind of drinking water extraction by thermal distillation is very efficient, and if the humidity in the sand layer is high enough, about 100 milliliters of drinking water can be extracted in half an hour. Moreover, after the filtration of the sand layer, the condensed water droplets no longer need to be re-sterilized and can be drunk directly.

At noon, the temperature in the entire desert reached the highest point of the day, and under the sun, the surface temperature reached an alarming height, and if you took off the combat boots on your feet and stepped on them, it would definitely cause burns to the skin on the soles of your feet.

Although the weather was maddening, in order to avoid heat cramps and heat prostration, Luo Hao did not take off the camouflage combat uniforms on their bodies, but on the contrary, they also spread the long sleeves of the camouflage uniforms and raised the collar to protect every inch of skin on their bodies from being harmed by the scorching sun and scorching sand.

Not only that, but they even wore all the cotton T-shirts and Arabic scarves in their backpacks. In this way, their sweat is absorbed by the clothes on their bodies, which retains the sweat on the skin, and the cooling effect of sweat evaporation also gives people a cooling feeling.

Luo Hao led the team to move as close to the shadow below the dunes as possible, so as to reduce the exposure to the sun.

Luo Hao compared the coordinates on the map, and then corrected the direction of the team from time to time through the compass, and in the process of advancing, several people continued to collect edible plants within their field of vision.

Unlike the deserts of the Americas, there is no average 1 here. 2 meters, a barrel-shaped cactus that produces more than one liter of cooking water. However, there is the acacia tree, a medium-sized tree that is widely distributed from Africa to Australia, and its roots can be extracted directly from edible water, while its seeds, young leaves and young stems need to be cooked before they can be eaten.

In addition, at present, on the route that Luo Hao and others walk, the most distributed is a creeping plant called "wild gourd". The plant is almost all edible, from its flowers, seeds, and young stems to the spherical berries that grow, which is a great source of food and water for the six people in Group B.

The six people in group B were lucky, and during the day's walking, they not only found three acacia trees, but also found two wild gourd groups, which fully replenished the poor materials they had on their bodies.

Without confirming what the supplies in the supply point were, Luo Hao was not ready to use the energy bar on his body, so Luo Hao would never give up this opportunity to replenish supplies.

Towards evening, Luo Hao spotted the fourth acacia tree in their journey, and after signaling the team to make a little news under the tree, he began to confirm the current location of the team according to the map and the compass in his hand.

Zhou Bai used his hands to pick up the sand layer at the root of the acacia tree, then pulled out his saber and cut the opening at the root of the tree, then wrapped a piece of cotton cloth around the wet root, sucked the water oozing from the incision, and collected it into a container that had been prepared long ago.

"Haozi, how far are we from the first supply point?" Xu Xudong threw the tender stem of a wild gourd into his mouth and chewed it slowly, sucking the water in the tender stem to relieve the thirst in his mouth.

Luo Hao put away the map in his hand, glanced at the few brothers around him, and asked: "The first supply point is still three kilometers away from our current location, and it is now five o'clock in the afternoon, whether we continue to rush and get supplies from the first supply point, or set up tents and camp in the same place, I follow everyone's opinions." ”

After a brief period of consideration, everyone agreed to hurry up and get supplies from the first supply point while the temperature was starting to drop, because just one day's journey had already consumed a third of everyone's fresh water, which was the result of deliberate savings.

Moreover, the surface of the earth still retains the temperature of the day, which is not too cold, and if the sky continues to darken, the temperature will drop further and it will not be suitable for marching.

Now that everyone's opinions were agreed, Luo Hao didn't linger any longer, and led the team towards the first supply point.

Almost an hour later, Group B arrived at the location of the first supply point on the map of the desert survival training. The straps of the supply packs were tied to a long-dried tree trunk.

Several people hurriedly dug out the supply bag buried in the desert, and then happily opened the backpack, but when they saw the contents of the backpack clearly, the smile on their faces instantly froze.

Because there is no saline and glucose water in the supply kit, but a snack that everyone is familiar with...... Small! Wash! Bear! Dry! Crisp! Face!

The ghost knows how Zhu Zhiyang got this kind of fried snack, but what was placed in front of the members of Group B was indeed a pack of retail prices of one dollar in the store, and the wholesale price was even only a few cents, and small toys were included with the bag.

Xu Xudong grabbed a pack of beautifully packaged, barbecue-flavored crispy noodles from the supply bag, and suddenly felt that the little raccoon pattern on the bag was so annoying, "I know the fox head is not so kind, but it's too fucking to give us supplies with this kind of thing that fools elementary school students!" ”

Luo Hao also picked up a packet of barbecue-flavored crispy noodles, tore open the packaging bag, threw away the seasoning package inside, and "crunched" the dough cake with a light salty taste.

Situ Kong looked at Xu Xudong, who was holding the crisp noodles with an unhappy face, broke off a piece of dough cake and stuffed it into his mouth, and said with a smile: "Don't be so picky, the fox head has prepared food for you, instead of fooling you with a backpack full of yellow sand." ”
