Centenarian loser cultivator Cassian, discarded by his clan and used by the poisoned Saintess as an antidote—left dying from the process—awakens the Karma Reversal System: all harm converts to cultivation. By swallowing poison and taking damage, he rapidly rises—avenging himself, earning elders' favor, and catching the eyes of multiple saintesses. From trash to Tiger Peak Saint Son, he slaps down rivals in this hilarious, high-energy fantasy hit.
