Chapter 557

Of course, the collection of drinking fresh water in this way is relatively passive, and the amount of water collected is relatively limited, which is difficult to meet the normal physiological needs of five people.

Generally speaking, when special forces obtain fresh water resources needed for survival in the wild, there are many methods, various and strange. But it is nothing more than collection, purification, desalination, or squeezing and filtering from animals and plants with rich water content.

Plants are easy to understand. Many water loving and shade loving plants are rich in relative water content. As long as their branches and leaves are crushed, filtered and squeezed, they can still obtain some fresh water resources. It can even be said optimistically that this fresh water resource also contains certain vitamins and trace elements needed by the human body. It's good for health.

But the water squeezed from animals is different.

Most of them are filtered and extracted from the body fluids of certain animals. This method is difficult to implement, and the extracted water source is also relatively heavy taste. It is difficult for ordinary people to drink it, unless they have to use it at a critical moment to protect their lives

However, at this time, for the elite Chinese special forces on the isolated island, the method and area of obtaining water source have certain limitations and scope. Not all methods can be used, nor can they be obtained anywhere.

First of all, the water source system on the whole island has been seriously polluted. There is no need to think about the way to obtain natural fresh water resources on the spot. Because the diffusion rate of water pollution is extremely fast, it is too expensive to test the degree of water pollution with their own lives. How can they take this risk.

Secondly, due to the serious pollution of the whole water source system, the vast majority of animals on the island were poisoned and died. Even the animals that survived the disaster had already escaped. After all, there is still a way out of the island. If you continue to stay, I'm afraid there will be only a dead end.

Moreover, if the whole water source system on the island is polluted, it is impossible for the plants on the island to be unaffected. Although this high-tech toxin has little impact on plant life and can not directly poison the plants, it is already contained in the plants, As a result, the possibility of extracting drinking water from plants with rich water content has also become an extravagant hope.

Therefore, at this time, the elite door of this team of Chinese special forces proposed to use fresh water. There are only the last two ways. One is the method of directly desalinating and extracting from seawater and condensing water vapor with cool rocks. They are already using it and have adopted it as much as possible within their control. However, this method is too passive, and the amount of fresh water collected is relatively small, which can not meet the survival needs of five team members at the same time.

In order to survive and take the initiative to obtain more water resources, they have also tried their best, but they can only find a way from the salty sea water.

However, desalination of seawater is a major issue that has been perplexing all mankind. It has taken thousands of years for human beings to research and invent many methods of desalination of seawater, but there are few processes, low energy consumption, high output, and there are still few sustainable ways and methods of desalination of seawater, which still remain in a relatively backward state.

Up to now, it has not even gone beyond the most primitive desalination procedure - natural distillation.

However, on the isolated island, other methods have been cut off. At the moment, the elite of this team of Chinese special forces, who seem to be facing a desperate situation, can only take the most primitive method of desalinating seawater.

First, take two special combat helmets, fill them with sea water, build them up and down in the same direction, and fix them in the sun. The helmet above takes off the camouflage net and the camouflage helmet cover on the helmet to expose the smooth metal shell.

Then, use the bamboo split in half and the middle bamboo wall has been removed as the drainage. In this way, a very simple distillation device with very original principle can be completed.

Since both helmets are fixed in the high-temperature sunlight, the seawater contained in the lower helmet begins to evaporate when heated. Once the water vapor evaporates, it will naturally first touch the metal surface of the upper helmet. Because the upper helmet is also filled with seawater, the temperature of the metal surface of the upper helmet is relatively low.

In this way, when the water vapor evaporated from below touches the relatively low-temperature metal surface above, it will naturally condense into water and gradually drop, and then drop on the drainage bamboo due to the action of gravity, and then drain out from under the helmet.

The distilled water drained out can be drunk directly.

There are many ways and means to obtain water sources. In short, special forces will do everything as long as they can obtain water sources to survive.

Although the fresh water collected and extracted by each device is not much, as long as the quantity is enough, the amount of fresh water obtained is barely enough.

In this way, the water source problem was barely solved.

As long as the enemy is not well rested and full, they suddenly attack them, otherwise they can barely continue to live. As long as the water source is used to solve the problem of filling the stomach, it will become relatively simple.

After all, special forces can not eat for days and nights, but it is absolutely impossible not to drink for days and nights.

Hunger doesn't kill people so quickly, but thirst really kills people soon. Even people have a sense of pain, discomfort and despair that life is worse than death, but there is nowhere to escape.

After solving the urgent task of drinking water. The elite of this team of Chinese special forces had to face a shocking and painful problem.

That's corpse odor, a terrible corpse odor that can make people collapse.

After several days and nights of bloody battle, the remains of the martyrs and the messy dead bodies of the enemy have long been everywhere. Those incomplete corpses, after several days and nights of fermentation and decay, send out bursts of suffocating terrible corpse odor, which can be called the magic attack in the game world.

Just imagine that the sun's extremely poisonous sun shines almost vertically on the island in the South Sea, carrying a lot of light and heat, so that the temperature on the island is far higher than that in other places. This is one of them.

Secondly, the four sides of the island are boundless sea. The high temperature of the sun scorched the boundless sea and transpiration out of countless water vapor. As a result, the humidity on the whole sea surface, including isolated islands, is extremely high.

Under the condition of high temperature and high humidity, microorganisms grow wildly, devour and decompose the martyrs' bodies and the enemy's bodies mercilessly.

That shocking degree of tragedy is unimaginable and even inhuman. Therefore, the strong corpse smell makes people hate why they have a nose, and why their sense of smell doesn't fail?

In particular, I watched the remains of my closest comrades in arms, gradually swallowed and decomposed by crazy microorganisms, gradually became incomplete, gradually exposed white bones, gradually distorted and ferocious But the sense of grief and helplessness that I can't help is almost heartbreaking and painful.

And the terrible images and terrible scenes on the whole island are like purgatory on earth.

This is a direct and terrible blow to human spirit.

Among all the people, the most painful and helpless is probably Cheng Chong, their formation captain. You know, he brought these people out and brought them to the battlefield. In addition, he repeatedly promised to take them back intact in front of his superiors. But what can he do now?

In fact, even when he retreated to the seaside to the north of the island, Cheng Chong never gave up the remains of any martyr. He put the martyrs' bodies together as neatly as possible, cleaned them up as much as possible and made them decent

That's my comrades in arms! They have been as fresh as themselves, have their own feelings, have their own careful thinking, small abacus They firmly believe that if they fall to the ground, the remaining comrades in arms will do the same as them.

However, when he found that no matter how hard he and his team members tried, they could not change the stubborn laws of nature and the almost inhuman cruelty in front of him, it can be imagined that his inner pain and struggle were so intense, intense and painful that he could hardly look directly at it.

However, even so, they must persevere and carry on. Even so, they must survive and fight and kowtow with the enemy, without exception.

Because the war is not over, the tasks assigned to them by their superiors have not been completed, the enemy has not been defeated, and they have not won the final victory.

As soldiers, they must insist that they never have the right to give up and quit.
