Whether it is jungle survival training or desert survival training, the first thing to consider is the issue of water sources. No matter where you are, rainwater can be one of the important ways to obtain water sources. However, in desert arid areas, the most obvious environmental feature is extremely scarce rainfall.
amount. And due to the arid characteristics of the desert, the falling rainwater quickly penetrates into the ground.
Therefore, instead of holding a container and praying to God for a heavy rain in a desert area, it is far less practical to find ways to obtain water yourself.
In addition to looking for edible plants growing in the desert, the quickest and easiest way to obtain water in the desert is to condense the water stored in the sand through thermal distillation.
Put your hand deep into the sand layer, feel the humidity of the sand layer through your skin, choose a place with high humidity, and dig a hole. Place a piece of plastic film over the hole, press the sun with a heavy object, and the moisture will be extracted from the ground.
Crystals form on the plastic film, and finally fall into a container placed under the plastic film and accumulate.
This method of extracting drinking water through thermal distillation is very efficient. If the humidity in the sand layer is high enough, about one hundred milliliters of drinking water can be extracted in half an hour. Moreover, after being filtered by the sand layer, the condensed water droplets no longer
It needs to be re-sterilized and can be consumed directly.
At noon, the temperature in the entire desert reaches the highest level of the day. Under the sun's rays, the surface temperature reaches an astonishing height. If you take off your combat boots and step directly on them, it will definitely cause burns to the skin on the soles of your feet.
Although the weather was crazy hot, in order to avoid heat cramps and thermal exhaustion, Luo Hao and the others did not take off their camouflage combat uniforms. Instead, they unfolded the long sleeves of their camouflage uniforms and raised their collars to protect themselves.
Every inch of skin on the body is protected from the harsh sunlight and hot wind and sand.
Not only that, they even put on all the pure cotton T-shirts and Arabian kerchiefs in their backpacks. In this way, their sweat will be absorbed by the clothes on their bodies, retaining the sweat on the skin, and the sweat evaporates to produce
The cooling effect can also give people a cool feeling.
Luo Hao led his team to move as close to the shadows under the sand dunes as possible to reduce sun exposure.
Luo Hao compared the coordinates on the map, and then used the compass to correct the team's direction from time to time. As they moved forward, several people continued to collect edible plants within their field of vision.
Unlike the American deserts, there is no barrel-shaped cactus here with an average height of 1.0 meters that can produce more than one liter of drinking water. However, there are acacia trees here, a medium-sized tree widely distributed from Africa to Australia.
Edible water can be extracted directly from the roots of the tree, but its seeds, young leaves, and young stems need to be cooked before they can be eaten.
In addition, on the route that people like Luo Hao are currently walking, a creeping plant called "wild gourd" is most widely distributed. From its flowers, seeds, tender stems to the spherical berries that grow,
Almost the whole body can be eaten, which is a very good source of food and water for the six people in group B.
The six people in Group B were very lucky. During a day's walking, they not only found three acacia trees, but also found two groups of wild gourds, which fully replenished their meager supplies.
Without confirming what supplies were in the supply, Luo Hao was not going to use the energy bars on his body, so Luo Hao would never give up this opportunity to replenish supplies.
As evening approached, Luo Hao discovered the fourth Acacia tree on their journey. After signaling the team to wait under the tree for a while, he began to confirm the team's current location based on the map and the compass in his hand.
Zhou Bai used his hands to pry open the sand layer at the root of the acacia tree, then pulled out a saber and cut an opening at the root of the tree. Then he wrapped a piece of cotton cloth around the wet root to absorb the water seeping out from the incision and collected it.
into the prepared container.
"Haozi, how far are we from the first supply?" Xu Xudong threw a young stem of a wild gourd into his mouth, chewed it slowly, and sucked the water in the stem to relieve the thirst in his mouth.
Luo Hao put away the map in his hand, looked at the brothers around him, and consulted: "The first supply is still three kilometers away from our current location. It is now five in the afternoon. We will continue on our way. From the first supply
I will follow everyone’s opinions on whether to obtain supplies or set up tents and camp on the spot.”
After a short consideration, everyone agreed to hurry up and get supplies from the first supply when the temperature started to drop, because just one day of traveling had already consumed one-third of everyone's fresh water.
Or the result of deliberate savings.
Moreover, the surface temperature still retains the daytime temperature, which is not too cold. If the sky continues to darken, the temperature will further drop and it will not be suitable for marching.
Now that everyone had reached a consensus, Luo Hao did not linger any longer and led the team towards the first supply.
Almost an hour later, Group B arrived at the location on the map where the first supply was located during this desert survival training. The strap of the supply bag was tied to a long-dried tree trunk.
Several people hurriedly dug out the supply bags buried in the desert, and then opened the backpacks with joy. However, when they saw clearly what was in the backpacks, the smiles on their faces froze instantly.
Because there is no saline and glucose water in the supply package as they imagined, but a snack that everyone is familiar with...! Raccoon! Bear! Dry! Crispy! Noodles!
Who knows how Zhu Zhiyang got such fried snacks, but what was placed in front of the members of Team B was indeed the retail price of one yuan a pack in the store, and the wholesale price was only a few cents. The pack also came with toys. Once
There was a time when raccoon noodles were a symbol of high status among students!
Xu Xudong grabbed a package of beautifully packaged barbecue-flavored crispy noodles from the supply bag. He suddenly felt that the raccoon pattern on the package was so annoying, "I know the fox head is not so kind, but give us something like this to fool students."
Making supplies is too damn cheating!"
Luo Hao also picked up a package of barbecue-flavored crispy noodles, tore open the package, threw away the seasoning packet inside, and gnawed on the lightly salty noodles with a crunch.
Situ Kong looked at Xu Xudong who was holding the crispy noodles and looked unhappy, broke off a piece of dough and stuffed it into his mouth, he chuckled and said: "Don't be so picky, the fox head has prepared something for you, instead of using a
It would be nice to fool you with a backpack full of yellow sand."
