Today is the one-year anniversary of the discharge of nuclear wastewater into the sea. I followed my family to the supermarket as usual to buy food. Suddenly, a large number of black clouds appeared in the sky, like the abyssal mouth of a huge wild beast. If you're not careful, you'll be swallowed by it.

Just as my family and I returned home, it started pouring rain. The rain today is very strange, with a strong fishy smell. The rainwater on the ground even has a fluorescent glow. I have a bad feeling about this.

An hour later, my premonition came true. I looked out of the window and saw Aunt Wang, who lives downstairs, drenched in rain, convulsing all over her body. Her skin turned red, and her limbs twisted abnormally. Then, layer by layer, the skin on her face started to peel off, revealing eerie white bones. Her mouth opened wide, twice the size it was before.

She looked extremely eerie. Just then, her husband rushed back with an umbrella. As soon as his hand touched Aunt Wang, she bit it off fiercely.

Aunt Wang ate her husband's hand. From a distance, I could even hear the sound of bones being broken.

Shortly after, the injured man began to transform, moving exactly like Aunt Wang. His eyes turned white, his pace slowed down, and his face became extremely terrifying, just like... the zombies I had seen in zombie movies before.

Then, a large number of people I knew all turned into this horrifying state. They bit anyone they saw, completely losing their sanity. I quickly ran to the door, locked it, and drew the curtains.

I solemnly said to my family, "Judgment day has come. From now on, we must not make loud noises, turn on lights at night, or go outside. Otherwise, we will be the ones who die."

At first, they didn't believe me. After secretly observing the situation outside, they fell silent for a long time. In the midst of the quiet environment, my 10-year-old sister suddenly burst into tears and said softly, "Sister, I'm scared."

I was scared too. I never thought I would experience these things in my lifetime, but I couldn't show it. I had to calm her down first. If she broke down and cried loudly, it would attract the zombies.

Returning to my room, I hugged a doll and bit my hand while silently shedding tears. I'm so afraid. I'm afraid that in the near future, I will also become an irrational zombie, afraid that I will harm my family without hesitation, afraid that I will turn against my close family members.

[Ding, host found. Now asking for your willingness: Hello, Xie Ning, I am System 001. I want to bind with you. Are you willing to accept my binding?]

I've read many novels before and I know systems are powerful. I said excitedly, "After I bind with you, can you end the apocalypse?"

[I'm sorry, I don't have the authority to do that right now. I'm just a money-making system that can only help you achieve your desire to get rich.]

I wiped away my tears and said, "Then I refuse to bind with you. I don't want money right now. Even if I have money, I might not have the life to spend it. In these last moments, I just want to be with my family."

System: [By completing the task, you can obtain a method to purify nuclear wastewater.]

I was intrigued. It continued, [After completing all the tasks, you can use the money you earn to purchase items from the system's store that can eradicate nuclear radiation. We also have a cure for the zombie virus, but you can only purchase these with the money you earn after completing the tasks.]

The root cause of the apocalypse is the mutation caused by nuclear contamination. Thinking back to the harmonious and peaceful days before, I gritted my teeth and said, "Alright, I'll do the tasks."
