Doomsday: My Grandpa Turns Out to Be Me

Also known as: My Golden Finger Is Actually Me from a Parallel World

Two outbreaks of infection have left countless people infected. All living things are mutating wildly, and plants and animals have evolved to an unprecedented degree, steadily squeezing humanity's living space.

A mysterious old man whose face is never seen injects Zheng Ji'an with a regression potion that gradually grants him animal abilities.

It gives Zheng Ji'an an eagle's range of vision, a frog's ability to track movement, a bear's sense of smell, a mantis shrimp's lightning-fast strike, a cat's jumping power, and all sorts of other powerful abilities.

Dandelions that silently parasitize human bodies, and dodder vines that devour all living things, spread everywhere and destroy everything.

Monsters from the ocean floor come ashore, and an island nation sends out a distress signal.

A massive nuclear war breaks out. Humanity is cast down from its throne and struggles to survive.
