I Became an Evolving Space Monster - Chapter 380

Kiro is a slave branded with a deadly collar, forced to work in brutal mines under the ruthless Kargal Empire. Each year, slaves are hunted for sport in the deadly Hunting Games—a fight to the death on a savage alien moon. This year, Kiro is chosen to play. Sent into a wilderness filled with monsters and traps, survival seems impossible. But something ancient watches from the shadows—and it has plans for him.

When a person dies, they either die light as a feather (aka unimportant) or heavy as Mt. Tai (aka very important).

This is the story of a crazy lich who possesses an internal game system and brings catastrophe to the entire world.

Beings that create and control monsters and demons, beings that build and reign over malicious labyrinths, the chosen individuals to possess an overwhelming Unique Skill… They are the Demon Lords.
