Falling into the Mortal World for You

As lovely as a celestial maiden, she stood amid falling willow fluff and snowflakes, dressed in a bright red wedding gown. Gripping a greatsword, she plunged it into the villain's chest and said: “Well, we've seen blood today, so it must be a lucky day. I'll take the blood from your heart to officiate my wedding to him!” The moment she was born, her own father tossed her into the mortal realm like a broken bowl, turning her into an ordinary mortal. Everyone thought she had long since been reduced to a pile of bones. But to everyone's astonishment, she survived. She even got a Thunder God for a father, a mysterious and powerful cultivator who insisted on becoming her master, and a divine phoenix for a companion. Born with an ordinary mortal body, she struggled to cultivate. Everyone around her doted on her as if she were useless, so her life wasn't all that bad. Until one day, the villain killed her senior brother and master. Her entire sect branded her a bringer of bad luck and humiliated her in every way, while her Thunder God father was executed on the God-Slaying Platform trying to save her. From then on, her temperament changed completely, and she became the notorious great demon of the Three Realms. When she flew into a rage and set out to kill every evildoer, everyone came forward to tell her to be kind. To hell with kindness. I'm not just going to kill them, I'm going to wipe out every one of those vile bastards.
