I'm a Decent Guy, but the System Isn't Decent

Gu Chen is constantly reborn in different worlds.

To stay alive, he has to keep completing the System's yin-absorption and yang-replenishment missions.

In each world, he gains a special ability.

"Ability: Change colors?"

"Wait, then changing the sun's color should be totally normal, right?"

"Hold on, are chromosomes colors too?"

"Wait a second, the brain controls the body through nerve signals. If I control the color of someone's central nervous system, could I turn them into a vegetable?"

One perilous cycle after another.

He struggles endlessly just to stay alive.
