    "Isn't that enough?" Wang Yuanzhen ran over from the camp impatiently. Wang Qinian raised his head and looked at him, his face covered with black smoke stains.  "Soon, soon." He replied.  Because the search team never came back, they could only find other ways to obtain pure water first. Without electricity and without a semipermeable membrane, the simplest and most direct way they could think of was to make distilled water.  Wang Qinian and a few people found some smooth steel pipes nearby and a large pot with a lid, and began to make a simple distilled water equipment.  Such equipment is not a problem for people like Wang Qinian who have made many tools in the apocalypse. The only problem is that they don't know whether the water they get can be drunk.  They have carefully filtered most of the impurities when fetching water from the river, but viruses and heavy metal impurities that are invisible to the naked eye cannot be filtered. It is difficult to truly remove harmful substances in the water with simple distillation methods. When these substances can also  When evaporating, the concentration of harmful substances contained in distilled water will be even higher than before.  "Captain Wang, please stand aside. I don't know if there is any problem with the steam." An assistant of Wang Qinian said to Wang Yuanzhen.  The crude equipment cannot be completely sealed, and water vapor is constantly emerging from those gaps.  "What a fuss." Wang Yuanzhen muttered, but still stood aside honestly.  Water began to drip down along the condenser tube made of steel pipes, and fell drop by drop into the stainless steel lunch box below. Everyone stared at it involuntarily, watching the crystal clear water drop by drop gather into groups and flakes, and finally  Submerged the entire lunch box floor.  "Should these be enough?" Wang Yuanzhen asked.  "Wait a moment." Wang Qinian said.  Different substances have different volatilization conditions. Although no one has turned into a monster due to inhaling water vapor, it is difficult to guarantee that those viruses will not enter the air with the water vapor after the water boils for a period of time.  He handed Wang Yuanzhen a mask and waited patiently for the lunch box to be filled with water.  It¡¯s hard to describe the value of those beating water splashes in people¡¯s hearts. After a long period of thirst, every drop of splashed water will make people feel sincerely regretful, and they will all lick their lips involuntarily, as if it is  The sweetest nectar in the world.  "Is that enough?" Wang Yuanzhen finally couldn't help but asked.  The lunch box was half full. Wang Qinian carefully placed a two-liter plastic bucket under the condenser pipe and carefully lifted the lunch box over.  "Old Zhang." He said to an old man who was already waiting next to him.  The base has already established a complete set of methods for testing water quality.  Lao Zhang came over with two small bowls and filled one with the distilled water he had just obtained, while the other carefully scooped some river water.  ¡°Keep it away a little, and be careful not to contaminate the distillation equipment.¡± Wang Qinian said to Lao Zhang.  The latter nodded, put the two bowls on the ground, pricked his finger with a needle, and squeezed the blood into the two bowls. ? ?Everyone held their breath, waiting for the results.  The blood drops fell into the two bowls respectively. At the beginning, they all gathered together and slowly spread to the surroundings.  But soon, the bowl placed far away began to behave strangely. The drops of blood began to gather together and tumble, as if some force was pushing them.  The blood beads in the bowl quickly shrank to a point and floated like plankton.  This is a force that cannot be ignored. Such a scene always reminds people of those mutants who have lost their humanity after mutation.  Wang Yuanzhen suddenly grabbed the changing bowl and poured the bloody water inside into the fire.  "Be careful!" Wang Qinian reminded.  Wang Yuanzhen simply threw the bowl into the fire.  There was still no change in the other bowl. Wang Qinian nodded to Lao Zhang, so Lao Zhang lifted the bowl.  The people around him raised their spears nervously. He smiled and drank the bowl of water.  For an old man like him who has no ability to work, this is the only contribution he can make to the base.  Wang Qinian started timing, and after five minutes, Lao Zhang still showed no abnormality. Wang Qinian carefully observed the whites of his eyes and tongue coating, but found no changes, and finally breathed a sigh of relief.  A burst of suppressed cheers erupted all around. People in the apocalypse have already learned to suppress their voices at all times, but at this moment, no one can remain calm.  Wang Yuanzhen threw off his mask, grabbed the lunch box, took a sip of water, and then handed it to the people around him. At this moment, they shared the water as if they were sharing old wine.  "Light the other fires as well." Wang Qinian said with a sense of accomplishment.  Together they made four sets of identical installations,It is now possible to operate simultaneously.  "Every bucket of water must be inspected before it can be drunk." He said to Lao Zhang.  "Don't be careless." "Don't worry." Lao Zhang nodded and said.  "I want to spread the news to the people below right away, so that the people below can feel at ease." Wang Yuanzhen said.  "This can only be a temporary measure." Wang Qinian said.  There was no problem with the water source, but they didn't have enough fuel.  Even if each person takes just one sip, more than 2,000 people will need 200 liters of distilled water, not to mention there are many more places that need water.  What is being burned now are furniture fragments unearthed from the ruins. They are limited in number and are not resistant to burning. The most important thing is that they emit a lot of pungent gas when burning.  No one would mind such a smell, but Wang Qinian was worried that it would attract monsters from a distance.  "Let's take care of the immediate needs first." Wang Yuanzhen didn't take his concerns to heart. There were sentries at the commanding heights around him, and he believed there would be enough time to evacuate the crowd.  "Zheng Shilei." Wang Qinian called the assistant over.  "I'll leave the distilled water to you. Be careful and don't make any mistakes. Don't forget, those river waters can turn people into monsters. You must personally inspect every bucket of water to see if they pass the test."  "Leave it to me." Zheng Shilei nodded.  This kind of thing is not very difficult and labor-intensive. All it requires is care and responsibility. Not long after, a search team came back and said it had found a working generator. Wang Qinian led most of the strong men on the way.  In the past, women, old people and half-grown children were left to Zheng Shilei.  "Be careful, don't touch that water." Zheng Shilei felt a little frustrated, but he finally understood the importance of the problem and patrolled among the four large pots non-stop.  "Your father is a bad guy! You are not a good person either" Suddenly a few boys were fighting together at the edge, and Zheng Shilei hurriedly ran over and pulled them away.  "What are you doing?" Zheng Shilei slapped them several times, and they all became honest all of a sudden.  There is no such thing as a child being ignorant in the apocalypse. A willful child will either kill his family or be beaten to the point of becoming sensible.  "He drank water secretly!" A boy about thirteen or fourteen years old said, pointing to the boy who had just been beaten.  ¡°His father is a thief, and he grew so fat because he ate the things his father stole!¡± Another boy who was with him added.  "Your dad is the thief!" The boy who was beaten until the corners of his eyes were bruised shouted angrily. He wanted to rush over and catch the boy who was speaking, but was kicked down by Zheng Shilei.  In fact, the boy is not that fat, but compared to other boys, he does stand out. Such a figure is very dazzling in the apocalypse.  "We still have to fight, right?" Zheng Shilei felt agitated. There was a bucket of undistilled river water near the place where they had just struggled. If they knocked over the bucket of water, the consequences would be serious.  "You still want to hit me, right?" He slapped each boy several times on the face and body, gathering them together.  "Do you know what that is?" Zheng Shilei said to the boys.  "If that water gets on you, you will turn into monsters! Use your brains! Stop fooling around!" He looked at the dry lips of those children, and his heart suddenly softened, so he picked up a clean cup and took it  A glass of water was given to each of them and they took a sip.  "Bring me some firewood!" he shouted loudly, and the boys dispersed in laughter, leaving only the boy who had been beaten standing there.  ¡°If you¡¯re a man, don¡¯t hold grudges.¡± Zheng Shilei said to him.  "You are all partners, and you will have to face the future together." "They are not my partners." The boy said in a voice that he could not hear.     "no!"
