The Reincarnated Assassin is a Genius Swordsman

For as long as he could remember, Raon had known only the weight of a collar—his will subjugated, his blade wielded not for himself, but for masters who saw him as nothing more than a tool to be pointed and unleashed. Every order carved another link into the chain that bound him, and every mission stained his hands with blood that was never truly his to shed. But fate, cruel and capricious, offered him a second chance: a new life, a new body, and a world that did not yet know his name. Yet even in rebirth, the ghost of his old existence refused to fade. Wrath—the smoldering ember of every indignity suffered, every choice stolen—remained coiled in the ashes of his broken leash. Where others might have sought peace or oblivion, Raon made a different choice. For the first time, his feet stand on ground of his own making, and his sword swings by the decree of his own heart. He will carve his path through any who dare to bar his way, be they mortal tyrants, ancient powers, or the divine themselves. In a world that would cage him once more, Raon will prove that the most dangerous weapon is not the one forged in steel, but the one tempered by an unyielding will.
