The Wandering Knight’s Survival Manual

After dying in an unexpected accident, Kim Yohan is reincarnated as Johann Aitz of the prestigious Aitz Family. Although born a noble, Johann sits at the very bottom of the household hierarchy in a ruthless medieval society where the law of the strong reigns supreme. Believing that the only person he can trust is himself, he realizes that survival in this brutal world requires only two things: money and power. While training relentlessly by applying knowledge from his modern life, Johann unexpectedly crosses paths with Kaegal, the Master of Poison from the empire's premier assassination organization, the Nesos Guild. This marks the beginning of Johann’s fierce struggle as he refuses to become mere prey in a merciless era.
