KILL SURGE is a dark isekai web novel built on a single, relentless engine: survival through violence that cannot ever fully stop. Mark is summoned into a dying world as a Slave Candidate, and the blessing he should have received fractures into a curse-and-boon loop. Any kill refills his body completely; any real lull in danger drains him toward death.
The first arc is an escape through a fortress designed to contain summoned assets—ritual halls, anti-magic corridors, specialist barracks, bureaucratic record vaults, and sewage underworks—where every fight changes the board: routes open and close, keys upgrade, heat escalates, records are burned, and wounds persist as limitations even when his meters refill. Dialogue stays sharp and functional; lore is revealed through action—seals, brands, ledgers, protocols—never through speeches.
As the series escalates across continents and institutions, Mark’s power does not “level up” from killing; it refines. He becomes cleaner, faster, more procedural—while an anti-cheese consequence accumulates: each refill subtly erodes cognitive control, compressing decision windows, dulling empathy, and twisting threat perception. The world’s corruption is not only a monster in the dark; it is rot embedded in systems that label people as assets. Mark’s answer is not salvation. It is enforcement.
