Chapter 24 Water Purification
Pu Zhi turned off the fire, opened the door and looked at him through the iron door: "What do you want to talk to me about?"
The aisle was filled with the smell of hot pot base. Zhang Xiaobai, who had been eating dry food for half a month, couldn't help swallowing.
Although he was very greedy, he still knew the importance of the matter. He held up a half bag of rice and said, "My grandma drank unclean water and got a fever. Here are about ten kilograms of rice. Can I exchange it for a box of fever-reducing medicine?"
"I don't lack rice." Pu Zhi neither refused nor agreed.
I didn't expect her to refuse so bluntly. People outside were fighting for these ten kilograms of rice, but she actually didn't even look at it.
More than a month after the apocalypse, Zhang Xiaobai has lost his former immaturity and become thinner. He purses his lips tightly, and his jawline is clearly visible, adding a sense of determination and broken strength to him.
After hesitating for a while, he took out three crystal cores from his pocket: "Then I'll use this to exchange, okay?"
Pu Zhi looked at the thing in his hand in surprise. He could count the number of times he had gone out with one hand. He was just an ordinary person without any special abilities, but he actually found the crystal core and got three of them. This kid had something.
"Okay, but I'm only giving you a discount this time because of our neighbor. I won't give you that discount next time."
Hearing that Pu Zhi agreed, Zhang Xiaobai excitedly raised his head, the corners of his mouth unconsciously raised, and his clenched hands tightened because of happiness: "Thank you, Sister Pu Zhi!"
Pu Zhi took out a box of antipyretic medicine from the room and handed it out through the gap in the iron door.
After getting the crystal core, she remembered the water purifier that had been vacant all this time, and said calmly as if she was saying that the weather was good today: "I have a water purifier. If you are willing, one crystal core can purify a bucket of water."
Now Zhang Xiaobai was completely uneasy. Since the end of the world, although there was water everywhere, none of the water was drinkable.
Because of drinking contaminated water, many people developed high fever and vomited, and quite a few died.
I anticipated that something was wrong on the first day of the apocalypse, and filled all the containers in my home with uncontaminated tap water, which allowed me to barely hold on for half a month.
Brother Guo and his family who live in 301 also listened to my reminder and stored a lot of water. The water for the two families was almost used up ten days ago, and it is difficult to get a sip of water every day.
Although I made a simple filtering device, the effect was not very ideal. My grandmother had a high fever because she drank the water that I purified.
If we had a water purifier, my grandma and I wouldn't have to just stare at the rice without being able to cook it.
He bowed to Pu Zhi excitedly, saying thank you all the time.
Pu Zhi waved her hand nonchalantly: "I don't know whether the water purifier can purify the water outside. When you are free, send me a bucket of water. The first bucket will be free. I will not be responsible if there is any problem.
Zhang Xiaobai nodded repeatedly, the gratitude in his expression did not seem fake, and he excitedly ran downstairs with the antipyretic medicine.
He wanted to tell his grandmother and Brother Guo the good news.
Not long after, Zhang Xiaobai brought a bucket of water that looked clean but actually had a slight fishy smell. Pu Zhi took it and asked him to come back for more in ten minutes.
Inside the house, a bucket of water was completely purified in three minutes. Pu Zhi scooped up a handful of water, put it to the tip of his nose and sniffed it. The odor was obviously much lighter and almost imperceptible. The filter part of the machine seemed to have turned a little black.
Qingyin curiously put the branch into the water and gave an evaluation.
: It doesn’t taste good.
After writing, he did not forget to shake off the water on his body.
Ten minutes later, Zhang Xiaobai came to fetch water on time, followed by the couple from 301 and Huang Dashan, a man living alone on the eighth floor.
The four people subconsciously swallowed the water as soon as they saw it. Long-term lack of water caused their throats to crack like dry loess, but at this moment they seemed to become moist again.
Xiao Ren stared at the four people closely, and Pu Zhi opened the door with confidence and took out the bucket.
"It's better to boil the water before drinking it. If there is any problem, I can't do anything about it."
The four of them nodded in unison, and the couple from 301 took out a crystal core first: "Let's order a bucket first, and it will be delivered later."
Pu Zhi took it generously and agreed.
Huang Dashan was still hesitating. He planned to wait until he was sure that the water was drinkable before handing over the crystal core. His intuition told him that this crystal core would definitely be of great use.
Zhang Xiaobai changed his medicine and had no extra crystal cores on him, so he did not order any more water.
From this bucket of water, 301 and 802 each scooped out a large portion, leaving most of it for themselves, enough to last for several days.
On the third floor, Zhang Xiaobai had just arrived at the door of the room when Lin Qingqing took out a crystal core and put it in his hand.
"Sister Qingqing, this won't do!" Zhang Xiaobai hurriedly put down the bucket and wanted to put it back, but was stopped by Lin Qingqing.
"I know you have no crystal cores. This is a little gift from my husband and me. If you hadn't reminded us to store water, we would have died of thirst."
Guo Shi stood gently behind Lin Qingqing, completely agreeing with his wife's decision.
Zhang Xiaobai lowered his head. His short hair had grown long enough to just cover his eyes.
His eyes were red with tears welling up in them, and he bit his lower lip tightly to prevent them from falling.
Guo Shi patted his shoulder vigorously. After all, he was still a 17-year-old boy and he had worked hard these days.
: "Your grandma is still waiting for water, go back quickly, if anyone wants to thank you, it's us who should thank you."
Zhang Xiaobai choked up and nodded: "When I find the crystal core, I will definitely return it to you."
After saying that, he picked up the bucket and opened and closed the door in one go.
Lin Qingqing wanted to say it was too late to return it.
Guo Shi and his wife looked at each other and smiled in tacit understanding. Xiaobai is a good child.
…
After their experiments, they found that boiling water after purification through a water purifier would only cause mild diarrhea and no other abnormalities.
Grandma Zhang's high fever subsided on the second day.
The only three families left in the unfinished building order one bucket of water every three days, which works out to one crystal core per day on average.
Although it's not much, it's enough. If you have a good relationship with them, you will have fewer worries in the future.
35 days after the end of the world.
Pu Zhi collected enough crystal cores to help Xiao Ren reach level two, and at the same time opened a clone card with a validity period of one hour.
After the upgrade, Xiaoren's body is two meters long, and he is one and a half meters tall when standing. His claws and teeth are sharper, and the fur on the surface has become harder, like a suit of armor, while the innermost part is still dense and soft fur, which plays a good role in keeping warm.
If Pu Zhi grows up a little bit, maybe he will be able to ride a car, but now he can only carry a car for a short distance.
To upgrade your superpower, you need 100 crystal cores of the same level. To upgrade to the third level, you need 100 second-level crystal cores, which means 10,000 first-level crystal cores.
If I add Qingyin and Xiaoren, I will need a total of 30,000 pieces, and I don’t know when I can get them all.
"Sister Pu! Are you there?"
Zhang Xiaobai's voice suddenly came from outside the door. Pu Zhi opened the door puzzledly. Didn't he order water every three days? Why did he come today?
