World Sweeper: Starting with the Devouring System

In my previous life, I was the world's greatest assassin, codenamed “Netherworld.” No one survived my blade.

In this life, the “Orderkeepers” organization awakened me and made me a cleaner specializing in hunting down transmigrators.

They told me: Kill enough people, and you can go home.

I went on a killing spree.

Gourmet System? I devour it with one slash. My blade can taste flavors and detect poison.

Reborn with foreknowledge? I cut away their memories. I can foresee the next three seconds.

A mighty cultivator? I shatter their Nascent Soul. My blade aura begins to slay gods.
