The Rise of the Underground King in a Fantasy World

Once the feared King of the Underworld, Leo ruled the underground mafia with unmatched power—until one night, he was cast into the abyss of death. Awakening in a pitch-black void, he stood face-to-face with Marcus, the God of Death. Instead of an end, Leo was offered a second chance: rebirth into a dangerous world brimming with magic, monsters, and gods vying for supremacy.

Chosen by Marcus to carry his will, Leo must conquer the World of Gods to elevate his patron above all others. Gifted with the mythic skill "Killer Slash" and guided by a mysterious system designed to enhance his abilities, Leo is thrown into a new life of peril and promise. His first challenge? Surviving an encounter with deadly wind wolves, a reminder that in this world, death is ever-present.

Determined to reclaim his title as the Underworld King, Leo sets his sights on Emberfall, a town where he plans to build a new empire—one that thrives in the shadows, just like before. But this time, he’ll rule not just with cunning and violence, but with the divine power of death itself. In a world full of rival god-chosen warriors, ancient magic, and ruthless monsters, Leo’s ambition is clear: conquer or die trying.
