Magus Reborn [Stubbing in Three Weeks] Novel

Kai, one of the last surviving mages in a dying world consumed by dark creatures and corrupted mana, performs a forbidden ritual to travel back in time. His goal: to prevent the apocalypse and honor his master's final wish. The ritual succeeds, but not as planned—he awakens thousands of years in the past, inhabiting the body of Arzan, a young nobleman who was murdered. Now trapped in a primitive magical era before the Golden Age of Magic, Kai must navigate immediate threats: defending his new territory from an incoming beast wave while hunting down his host's killer. As he works to reclaim his former powers in a world where magical knowledge and techniques are far less advanced, he realizes he has an unprecedented opportunity. With his future knowledge and expertise, he might be able to alter the course of history itself and prevent the catastrophic fall of civilization he escaped from.
