In 2177, underground cities descend upon the world, overturning its rules.
This is an age of universal exploration, where strength reigns supreme. And I, Bai Lu, am merely a cleaner at the very bottom of the city, tasked with clearing battlefields after the powerful have fought, scraping by amid blood and stench.
An accident, and a battered, rusty knife from a treasure chest, let me glimpse another side of the world: invisible “threads” connect all things!
Betrayed by greedy companions and made a monster’s target? I sever its [Target] thread with one slash and make it suffer the consequences!
A monster’s deadly charge? I cut its [Charge] thread with one slash, leaving it standing there, unable to move.
