I am bound to a doomsday ark system, and I must constantly collect materials to upgrade the spacecraft.
I picked up a porcelain doll-like beauty on the road. He was so weak that he couldn't even unscrew the bottle cap.
Others ridiculed: "This kind of vase will not survive more than three days in the apocalypse."
I protected him behind me and watched him slowly push up his gold-rimmed glasses.
That night, he used the juice of mutated plants to prepare an anti-enemy medicine and saved the entire camp.
Later I learned that he held the core secrets of the virus that could destroy the world in his mind.
When the strongest zombie wave surrounded the city, he held my hand with a pale face: "Don't be afraid, I will give them a big gift."
