The biting wind carries the stench of iron and fear across a brutal medieval society, where the strong devour the weak without a second thought. Here, lineage might grant a name, but true power is bought with coin and blood. A harsh truth hangs in the air: trust no one but yourself, for every shadow hides a threat, and every smile conceals a blade. This is a world where being born a noble offers little comfort if you sit at the bottom of the food chain.

Yet, into this cutthroat realm, a new soul awakens. Once Kim Yohan, he now wears the skin of Johann Aitz, the lowliest son of a prestigious noble family, burdened by a forgotten life of modern knowledge. He trains relentlessly, honing skills alien to this age, determined not to be another casualty. But his desperate fight for survival takes a terrifying turn when he crosses paths with Kaegal, the infamous Master of Poison of the Empire’s greatest assassination guild, the Nesos Guild. Can a single man truly escape becoming prey in such a brutal era?
