Medieval Demon Hunter's Legend

A soul awakens in a brutal medieval world clutching a forbidden tome bound in flesh and blood—a grimoire that can forge anything from the void. Every demon slain, every law mastered, brings him closer to godhood. But in this savage realm, he is both the hunter stalking monsters and the prey hunted by forces beyond comprehension. His only weapon is the cursed book that chose him. His only path is written in blood.
