After Becoming a Cannon-Fodder Demon Cultivator, I Tore Up the Heavenly Dao's Script

[Strong Female Lead] [Plot-Driven] [Romance] [No Cheating] [Twists] [Light Ensemble Cast] [Happy Ending] A clear-headed, composed female lead. No System. Growth and progression, with a semi-traditional cultivation setting. This is not a mindless power fantasy: the entire plot revolves around the heroine. The heroine isn't a pushover. She may resort to unscrupulous methods, act domineering or scheming, or play dumb to fool her enemies, but she also has a soft side. All her reactions are shaped by how the plot unfolds. (Transmigrated into the body of an early-death supporting character with the same name? My younger sister gets the female lead's script? I don't even have a golden finger, and you're telling me I'll die in a year? A chaotic, unfamiliar world, an unknown cause of death, and a conspiracy gradually coming to light. Just when she thinks it will all be over, a twist arrives.) [In this world of humans, demons, and devils, I became a demon in this life, and I'll cultivate immortality all the same.] [What's going on? Did I break the script by changing it? The heroine's little sister keeps shoving spiritual treasures at me: "Sister, if you don't want them, it means you don't love me!" The fox gentleman keeps insisting they should only be friends, but in truth: "A Wei, once I've fattened you up and taken good care of you, I'll eventually warm you up and carry you off!" The warm-hearted phoenix... (Where's my part? Has my scene not come yet?) Someone... (Don't say that, I don't even have a shadow.)] P.S. Updates will begin once the main story is posted.
