What got summoned was the world’s strongest sociopath.

Hutson, a man reborn into a ruthless and dangerous world, now inhabits the body of a young hunter in a small barony. With no connections and nothing to his name, he must rely on his sharp mind and cunning to rise through a medieval-like society. As he climbs the social ladder, he uncovers a terrifying truth: wizards, beings far more powerful than any knight or noble, rule over the world. Driven by this discovery, Hutson throws himself into the pursuit of wizardry—a path darker and more brutal than he could ever have imagined. In a world where betrayal lurks around every corner, Hutson seeks what all others desire: immortality. With his intellect and ruthlessness, he will stop at nothing to claim it for himself.
