After losing his life in an unforeseen accident, Kim Yohan is reincarnated as Johann Aitz, a member of the renowned Aitz Family.

Although born into nobility, Johann quickly realizes that his status means little, as he stands at the very bottom of his family’s hierarchy. Worse still, the world he has entered is a harsh medieval society where only the strong survive.

“The only one you can truly rely on is yourself.”

In this ruthless era, survival depends on two things alone: power and wealth.

Using the knowledge and experience from his previous modern life, Johann trains relentlessly to strengthen himself. Along the way, he crosses paths with Kaegal, the infamous Master of Poison from the Nesos Guild—the Empire’s most feared assassination organization.

What follows is Johann’s relentless fight to survive in a savage world where the weak are destined to become prey.
