Regressed Hunter's Dungeon Manual

Hyeonseok died a miserable death, blind and betrayed, abandoned in the depths of a brutal dungeon. But fate had other plans. He opened his eyes, not only seeing again but back in time! Armed with perfect foresight and razor-sharp senses from his past life, he knows every dungeon secret, every monster weakness, and most importantly, the treacherous individuals who left him to die. Now, he's not just leveling up; he's setting intricate traps, exploiting market fluctuations, and forcing his enemies into servitude with a terrifying, addictive elixir. His former tormentors thought they were cunning. They have no idea they're about to become his personal meat shields, puppets in a deadly game. But with a second chance, how far will Hyeonseok go to rewrite his cruel destiny?
