Siheyuan: 55 years, starting from a buyer

"Masters, Brother Ming, please be alert to the surrounding environment. The zombies move very quickly. If there are any changes, please be careful. We will wait until it is completely safe before picking up Xiaobao."

"Okay, but Xiaowei, as a girl, how can you be so bold? You handled it very calmly from beginning to end, and never showed any panic." Zhang Sheng praised Yu Xiaowei. A 19-year-old woman faced this situation and behaved more calmly and calmly, even calmer than Chen Yang.

Thinking of the scene of Yu Xiaowei holding a baseball bat to fight zombies, Zhang Sheng couldn't help but recall the scene of his first duel with Yu Xiaowei. The museum director Ma Boran once patted his chest and solemnly promised: He is not a person who accepts disciples casually.

However, Zhang Sheng was now somewhat puzzled by this aura - Yu Xiaowei was only eighteen years old, why was she so sophisticated and experienced? Her calmness and changes in dealing with zombies seemed to exceed her actual age and the immaturity that should be expected of her.

"Master, you see, I have had a special hobby since I was young, which is doomsday movies. When I was little, I often thought about how to protect myself if the doomsday came one day. The more I think about it, the less afraid I am. With a master like you by my side, why should I be afraid of zombies!" Yu Xiaowei responded with a smile.

"This **, your mouth is getting sweeter and sweeter." Zhang Sheng smiled slightly. In his opinion, it might be just an unintentional remark, but Yu Xiaowei in front of him is still the lively and lovely teenage girl.

Yu Xiaowei smiled softly, then turned to the door: "I'm going to try the door with the key next, you guys pay attention to the movements around you, if there are zombies, use the weapons in your hands to fight as much as possible. Brother Yin, please keep your special ability."

Although he survived for five years in the apocalypse in his previous life without activating any special powers or experiencing any mutations, and was merely a fake air-powered person with stronger immunity to the original virus, Yu Xiaowei still understood that the way to identify the power of people with special powers had certain identification standards in various bases. Even if it was Yin Guang's light-attributed special power that was more advantageous against zombies, the power that a person with special powers could release in the initial stage was also very limited.

At this time, Yu Xiaowei, who was chatting while testing the door lock, was very lucky. After the second try, the door opened with a click.

### Chapter 49 Uncertain Water Pollution

"I'm going to open the door, get ready." When the sound of the key turning in the door lock rang out, Yu Xiaowei looked at Zhang Sheng and Yin, and they nodded to each other to indicate that they were ready.

With the third command, the door opened. It was quiet and unusual inside, without any unusual sounds.

Zhang Sheng and Yin finally breathed a sigh of relief, only Yu Xiaowei walked cautiously towards the space inside the door.

Only after she was sure that the villa was indeed uninhabited did she finally put down the stone in her heart:

"Master, Brother Yin and I will tidy up the room! You can bring Xiaobao up first, but be careful when you go out."

Zhang Sheng nodded, "Okay, got it." Then, he picked up the spring stick and went out. Everything around him seemed very peaceful. He drove the car into the yard and locked the iron gate. Then he picked up the sleeping Xiaobao from the car and took him into the villa.

At this time, Xiaobao's fever had gone down. However, he had not yet woken up. Based on his experience in his previous life, Yu Xiaowei felt that this time, Xiaobao would most likely be able to activate his special powers after waking up.

However, for safety reasons, Yu Xiaowei still arranged Xiaobao in a room on the first floor and locked the door from the outside. In order to prevent any possible situation, a table was even placed next to the door to block it. Even if he unfortunately turned into a zombie, it would be unlikely for a zero-level intelligent zombie to open the door. The worst that could happen was that he would just hit it with force.

In addition, placing him on the first floor kept him away from the smell and noise of other living people, which reduced the level of violence. They would be more prepared when they came back to find this situation. This was just a precautionary measure, because Yu Xiaowei speculated that this child was likely to be a person with special abilities, and the fact that he did not lose consciousness proved his stable state.

Chang Jun looked through the medicines she brought back from the hospital. Xiaobao had already been disinfected and had his fever reduced. The remaining saline solution and glucose were the most basic supplies used to maintain Xiaobao's physical condition. Considering that Xiaobao had not eaten or taken in water yet and could not get additional nutrition such as protein, these basic supplies were given to Xiaobao.

"Let's all go upstairs and rest for a while!" Chang Yun finished the infusion on Xiaobao and said, "I have mastered the time. I will come down to remove the needle later."

Don't worry too much about my brother. I suggested that we eat something first. In the early days of the end of the world, the water and electricity supply were still sufficient. Although there was no one to supervise it, it could still operate for a certain period of time. Because of the space I brought, I had a complete set of kitchen utensils and seasonings.

But regarding the water source, Yu Xiaowei does not want to rely on the water in the pipes for drinking. He knows that although the water quality in the early post-apocalyptic period is not absolutely unfit for drinking, he still needs to be cautious to avoid causing unnecessary crises. There is no big problem with the water itself, and nature has its own self-purification system.

However, the most important thing to be vigilant about is whether the source of the water supply has been infected by zombies. If it is drunk directly without being given enough time to clean itself, the consequences may be disastrous.

Then, Yu Xiaowei looked at Zhang Sheng who was standing beside him and said, "Second Master, please go again and inform those people to avoid drinking water from the pipes as much as possible. This incident may be related to the strange snowfall yesterday. The snowfall mixed with the water. I don't know what kind of impact it will have on humans after drinking it."

If she was lucky, she might be able to use the small amount of pathogens that entered her body to transform the child into a person with special abilities. But what if she was unlucky? Yu Xiaowei was not willing to take this gamble. Without any definite information about the existence of water-based special abilities, she had already prepared herself and stockpiled some bottled water.

Although there were some disgusting people among them, most of them were normal people. She had neither shown them too much kindness nor intended to harm them. Considering this reason, after some consideration, Yu Xiaowei passed the news to this group of people. Whether they would accept this advice in their final actions was not within her decision-making range.

Looking at Yu Xiaowei who had a determined expression in front of him, "Well, Xiaowei, this kid has a good heart. It won't take much effort to remind others. It's a good deed." Yu Xiaowei nodded and followed Zhang Sheng out of the room to inform the other party.

Seeing Yu Xiaowei also come out, Zhang Sheng looked quite surprised and said, "I can go by myself."

"No, Second Master, we are short of something for cooking! I want to bring some ingredients and water in." Yu Xiaowei replied with a smile.

When Zhang Sheng heard what Yu Xiaowei said, he couldn't help but smile: "I didn't even think about it so much, it's really useless."

Shang Yun witnessed Yu Xiaowei walking out of the door and followed him. The two followed Yu Xiaowei's instructions and moved all the supplies out of the trunk of the car. At the same time, Yu Xiaowei pretended to be looking for something in the bag, but actually took the opportunity to put some seasonings and supplies into the bag, and then took the bag into the villa.

Although Yu Xiaowei occasionally visited the villa community in her previous life, she also lived there many times after cleaning it because it was relatively close to the base. However, during one of her team's trips, a water-based supernatural provided water supply, and she only needed to use this part of the water source for cleaning work. The rest of the time, she relied more on the water for daily life.

However, I have only been there a few times and do not know the surrounding area very well. The source of the water supply has never been specifically explored, so not using tap water is a practice to minimize consumption. But this does not mean that it cannot be used - if the body is not damaged and it is ensured that the water is not mixed with any contaminants, it is possible to carry out daily bathing and washing activities to a certain extent.

After the end of the world, Pingyuanjing, the national capital, began to move the core scientific research team to a safe place after experiencing the early chaos. Then they began to study the dead, and found that under the intrusion of the dead, whether animals, plants or humans, they may mutate, and they have similar reaction mechanisms to humans.

As for soil and water quality, as long as they are not in areas attacked by the dead or the plants are not polluted, the products grown will not be threatened. The same principle applies to water sources. Even if you ingest water that smells of the dead or is mixed with the dead, there is not much risk; nature has a strong self-purification ability.

When it comes to polluted water resources, once the source of pollution is removed, retesting after a period of time will reveal that the water quality has returned to normal, but this process of repair takes time.

But in some extreme cases, a small base suffered catastrophic consequences due to a temporary pollution source, so each base strictly guards the water source. In the wasteland, human ** is common, and it is heartbreaking to see it.

In the early stages, even if those teams treated them unkindly, Yu Xiaowei was still unwilling to lose a large number of lives in vain, even though there were elements among them that he wanted to get rid of.

A further consideration is the concern for their own safety: when leaving the country tomorrow, it is undoubtedly not ideal for many people to dance with zombies. In the context of the end of the world, there are many ways to eliminate Cha Yang, and delaying this time is not important.

After a heavy loss caused by a large change in water use, large bases have paid special attention to this, because even a slight negligence may lead to a tragedy.

Later, they would often use smaller animals, such as mice, to test the water quality, and only allow members of the base to enjoy it after confirming that it was safe.
