"Still not good?" Wang Yuanzhen ran from the camp impatiently, Wang Qinian raised his head and looked at him, his face was full of black cigarette stains.

"It's coming, it's coming." He replied.

Because the search team never returned, they could only find a way to obtain pure water by other means first, without electricity and semi-permeable membranes, and the simplest and most direct way they could think of was to make zuò distilled water.

Wang Qinian led a few people to find some smooth steel pipes nearby, and found a cauldron with a lid, so he began to make a simple distilled water equipment.

Such equipment is not a problem for people like Wang Qinian, who have already made many tools in the last days, the only problem is that they don't know whether the water they get can be drunk or not.

They have carefully filtered most of the impurities when they take water from the river, but those viruses and heavy metal impurities that are invisible to the naked eye cannot be filtered, and it is difficult for simple distillation methods to really remove harmful substances from the water, and when these substances can also be volatile, the concentration of harmful substances in the distilled water will be even higher than the original.

"Captain Wang, stand out a little, I don't know if there is a problem with these steames." One of Wang Qinian's assistants said to Wang Yuanzhen. Rudimentary equipment could not be completely sealed, and water vapor was constantly coming out of those cracks.

"What a fuss." Wang Yuanzhen muttered, but still honestly stood aside.

Water began to drip down the condenser pipe made of steel pipes, and drop by drop fell into the stainless steel lunch box below, and everyone couldn't help but stare at it, watching the crystal clear water gather into a ball and piece of water, and finally flood the entire lunch box floor.

"That's enough, right?" Wang Yuanzhen asked.

"Wait a little longer." Wang Qinian said. Although no one has turned into a monster due to inhalation of water vapor for the time being, it is difficult to guarantee that those viruses will not enter the air with water vapor after boiling for a period of time. He handed Wang Yuanzhen a mask and waited patiently for the lunch box to slowly fill with water.

It's hard to describe the value of those beating splashes in people's hearts, after a long period of thirst, every drop of water that splashes out of the water will make people feel sincerely sorry, and they are all involuntarily licking their lips, as if it is the sweetest nectar in the world.

"Enough!" Wang Yuanzhen finally couldn't help but ask. The lunch box was already half full, so Wang Qinian carefully connected a two-liter plastic bucket under the condenser tube and carefully lifted the lunch box over.

"Lao Zhang." He said to an old man who was already waiting next to him. The base has already determined a complete set of methods to test water quality.

Lao Zhang came over with two small bowls and filled one of them with the distilled water he had just obtained, while the other carefully scooped some river water.

"Take a little away and be careful not to contaminate the distillation equipment." Wang Qinian said to Lao Zhang.

The latter nodded, put both bowls on the ground, and pricked his fingers with a needle, squeezing the blood into each of them.

Everyone held their breath and waited for the results.

The droplets of blood fell into two separate bowls, and at first, they all gathered together and slowly spread to the periphery. But soon, the bowl in the distance began to grow weird, and the drops of blood began to gather together and tumble, as if something was pushing them. The blood in the bowl quickly shrank into a dot and floated like plankton.

It's a force to be reckoned with, and it's always reminiscent of mutants who have lost their humanity after mutation.

Wang Yuanzhen suddenly grabbed the bowl that was changing, and splashed the blood and water inside into the fire.

"Beware!" Wang Qinian reminded.

Wang Yuanzhen simply threw the bowl into the fire.

There was still no change in the other bowl, Wang Qinian nodded at Lao Zhang, so Lao Zhang lifted the bowl.

The people around him raised their spears nervously, and he smiled and drank the bowl of water. For an old man like him, who is no longer able to work, this is the only contribution he can make to the base.

Wang Qi began to time, five minutes later, Lao Zhang still did not look unusual, Wang Qinian carefully observed the whites of his eyes and tongue, there was no change, and finally breathed a sigh of relief.

There was a burst of suppressed cheers around him, and people in the last days had long since learned to suppress their voices all the time, but no one could remain calm at such a moment. Wang Yuanzhen threw off his mask, grabbed the lunch box, drank a large sip of water, and then handed it to the people around him, at this moment, they shared the water as if they were sharing aged good wine.

"Light the other fires as well." Wang Qinian said with a sense of accomplishment. Together, they made four identical devices, which were now ready to work at the same time.

"Every bucket of water has to be checked before you can drink it." He said to Lao Zhang. "Don't be careless."

"Don't worry." Lao Zhang nodded and said.

"I'm going to send the news down there right away to reassure the people below." Wang Yuanzhen said.

"This can only be a stopgap measure." Wang Qinian said. There is no problem with the source of water, but they do not have enough fuel. Even if everyone only takes one sip, more than 2,000 people need 200 liters of distilled water, not to mention that there are many more places where water is needed.

The pieces of furniture that are now burned are all scraps of furniture that have been turned out of the ruins, they are limited in number, and they are not resistant to burning, and the most important thing is that they emit a large amount of pungent gas when burned. No one would mind the smell, but Wang Qinian was worried about whether it would lure the monster from a distance.

"Let's solve the urgent need first." Wang Yuanzhen didn't take his concerns to heart, there were sentinels on the commanding heights around him, and he believed that there would be enough time to evacuate the crowd.

"Zheng Shilei." Wang Qinian called the assistant just now. "I'll leave the distilled water to you, be careful, don't make any mistakes. Don't forget, those rivers are monsters, and you'll have to check every bucket of water yourself and see them pass. ”

"Leave it to me." Zheng Shilei nodded.

The difficulty of such a thing is not high, the labor intensity is not large, all that is needed is to be careful and responsible, and it didn't take long for a search team to come back and say that they had found a working motor, and Wang Qinian rushed over with most of the sturdy men, leaving the women, the old and the half-grown children to Zheng Shilei.

"Be careful, don't touch the water." Zheng Shilei felt a little frustrated, but he finally understood the importance of the problem, and kept patrolling between the four cauldrons.

“…… Your dad is a badass! You're not a good thing either......"

Suddenly, a few boys scuffled together on the very edge, and Zheng Shilei hurriedly ran over and pulled them away.

"What are you doing?" Zheng Shilei gave them a few slaps alone, and they were all honest all of a sudden. In the last days, there is no such thing as a child who is ignorant, and a wayward child will either die with his family, or he has already been beaten to be sensible.

"He steals water!" A boy of about thirteen or fourteen years old pointed to the boy who had just been beaten.

"His dad is a thief, he just ate what his dad stole to get so fat!" Another boy who was with him added.

"Your dad is a thief!" The boy who had been beaten and bruised in the corners of his eyes shouted angrily, and he tried to pounce and grab the boy who was talking, but was kicked down by Zheng Shilei. In fact, the boy is not very fat, but compared to other boys, he does stand out, and such a body shape is very dazzling in the last days.

"You're going to fight, aren't you?" Zheng Shilei felt irritated for a while, there was a bucket of undistilled river water near the place where they scuffled just now, and if they knocked over this bucket of water, the consequences would be very severe. "Still fighting, huh?" He slapped each boy in the face and brought them together.

"Do you know what that is?" Zheng Shilei said to the boys. "If that water gets on you, you're going to be monsters! Use your brains! Don't fool around! ”

He looked at the children's dry lips, and his heart suddenly softened, so he picked up a clean cup and took a glass of water for each of them to take a sip.

"Bring me firewood!" He shouted loudly, and the boys laughed and scattered, leaving only the boy who had been beaten standing still.

"If it's a man, don't hold grudges." Zheng Shilei said to him. "You are all partners, and you will have to face it together in the days to come."

"They're not my buddies." The boy said in a voice he couldn't hear.

"It's not!"
