My Body, A Demon's Vessel

Waking up in a reeking, corpse-strewn sewer was horrifying. For Xu Qiyun, transmigrated into the body of a pathetic cultist named Donald Grant, it was just the start. He'd hijacked a vessel fresh from a botched Demon Descension Ceremony, now surrounded by rotting remnants of an occult ritual. The ritual was supposed to summon a demon. Instead, a dark red bead embedded itself in his soul, granting terrifying, unwanted power: the ability to perceive the unseen grey mist of corruption on others and halt violent attackers with a chilling thought. Yet, this gift came with a horrifying price – a malevolent, alien consciousness that surfaces unbidden, clawing for control. Now, trapped between a powerful, illegal cult and the looming Inquisition, Donald must unravel the secrets of his predecessor's cursed life, navigate a gaslit steampunk city, and somehow exorcise the demon within before his new life becomes a literal hell, controlled by another.
