In the apocalypse, I have a flying house with unlimited upgrades.

This morning, my father, who had been unemployed for several months, was out looking for odd jobs when he suddenly received a call from his foreman informing him that he was returning to work.

The project is on a tight schedule and demanding, requiring preparations for working through the night. However, the pay is generous; agreeing to work will earn you three days' wages, more than twenty times the usual amount.

My father was overjoyed and told me to take good care of my younger sister, promising to celebrate her birthday after he finished his work. Although I was puzzled, I didn't dare to object.

After all, I've been three months behind on rent, and it's been almost a month since the new semester started. I'm still behind on tuition, and there's been new news about my sister's amblyopia treatment.

This is good news; in an instant, there was hope for everything.

"After my father left, I prepared delicious food for my younger sister, all her favorite dishes. On my way to tutor her classmates, I had a vague premonition that something was wrong..."

"I had only been in tutoring for less than half an hour when my classmate's father rushed back. He looked panicked, shouting that something terrible was about to happen, and yelling at his wife and daughter to quickly pack their things."

But when he saw that there were outsiders present, he suddenly composed himself, and a strong sense of unease welled up inside me. He must have found out something, but I couldn't muster the courage to ask him..."

"My tutoring session was interrupted. My classmate's father said he would help find a car to take me away. He made several phone calls, and his face was serious. I knew he couldn't do it."

Subsequently, under the insistence of the classmate's father, the family quickly packed their personal belongings.

The boy's diary entry ended there. He then turned on his phone's video recording function and thoughtfully plugged it in.

The video was very long, recording how he restrained himself after being bitten and how he transformed into a zombie... until Ye Ziming's figure appeared on the screen, and then the video abruptly stopped.

Xu Shuai put away his phone, his eyes filled with complex emotions, feeling as if a thousand-pound weight was pressing down on his chest and back at the same time.

He looked at the boy who came from a poor family but was kind-hearted, never complained about the hardships of life, and was instead positive, confident and sunny.

Even before he turned into a zombie, he still cared deeply for his family and worried about his sister's safety.

They are even less willing to cause trouble for others because of their own behavior, and choose to bind themselves before their rationality disappears.

If there is anyone whom Xu Shuai absolutely must save, it is this kind of young man with a pure and innocent heart.

Xu Shuai accepted the task entrusted to him by the boy without complaint.

He felt heavy-hearted, but he also quickly extracted some hidden information from the boy's diary.

It has been discovered that painkillers can indeed prolong the infection period after being infected by zombies.

The process from the boy being infected to his transformation into a zombie lasted for ten minutes, while Xu Shuai had previously observed a zombie transformation time of only one minute.

If painkillers are used to prolong the duration of pain, it is worth exploring whether the duration can be further extended, and by how much.

The close-up footage of the teenager's transformation process is a valuable research sample video.

Perhaps one day, he can hand this video over to biological research experts.

This will accelerate the research into a potion that can prevent or even cure the zombie virus.

"Ye Zi, keep this phone safe. When you have time, edit the video and remember to delete the long parts."

He handed the phone, which was overheating and lagging due to excessive memory usage, to Ye Ziming, stopping the latter from showing mercy to the zombie.

"Alright, close and lock the door later, and don't disturb him anymore. That's all we can do."

"Ye Zi, you take the two of them and continue the investigation. I'll go deal with the old zombie downstairs."

After assigning tasks, Xu Shuai picked up the ropes scattered on the ground and hurried downstairs.
