Douluo Continent: Half-level Innate Realm, but a Sword Cultivator with a Heart-Only Mind

There's a type of sword cultivator who's incredibly cunning. You ask him if he won or lost, and he says he's achieved enlightenment. You ask him if he has any last words, and he says he still has unfulfilled wishes. You shatter the sword in his hand, and he says, "No sword in hand, but a sword in heart." ...Qi Dao transmigrates to the Douluo Continent, his martial soul undergoing a malignant mutation, leaving him only at the half-level of the Innate Realm. Facing his parents' comfort, his consciousness rewinds to the past, he holds his sword and questions himself, experiencing a sudden enlightenment. His will becomes as firm as divine iron. From then on, the continent loses a useless person and gains a sword cultivator—a sword cultivator of the heart.
