Practicing Only Demonic Arts, I Reduced the Heroine to Tears

Free of systems and set against a sweeping backdrop of imperial courts and martial arts realms, this gripping tale follows a practitioner forced down a dark path. "You were meant to be a righteous person; why indulge in heterodox and demonic ways?" "You think I wanted to? Every orthodox technique that catches my eye gets corrupted and 'demonicized' by an inexplicable force, transforming into a self-destructive taboo art that hurts me by eight hundred while annihilating the enemy by a hundred thousand! If not for my indestructible jade-figurine body, how could I ever roam the world unchecked?" "If you, this fiend, do not repent, do not blame my sword for being merciless!" "You can't even beat me—do you actually enjoy being defeated, captured, and tortured by me?" "I beg you to practice something else! Otherwise... otherwise I'll die right here in front of you!" "Just how many times have I saved you? With me around, don't you know whether you're even capable of dying?" "Please don't give up on yourself! Look, I'll go gather the others to discuss this together. Surely there's a way to help you break your demonic addiction!" "Don't! If they ever find out about each other, that's what will truly destroy me!"
