Using My Enemies as Fuel, I Defy the Heavenly Dao

[Female-Led + No CP + Revenge and Punishing Scumbags + Cultivation + Going Crazy + Crawling Through the Dark] Yan Chu transmigrates into a cultivation novel as the black-hearted female supporting character, only to be poisoned by her scumbag stepfather and his mistress. Her scumbag stepfather and fake sister tear open her stomach and rummage through her entrails, laughing as they tell her she doesn't deserve to live in this world. Because of her Yin constitution, Ye Huan, the sect master of the Hehuan Sect, turns her into a human cauldron, tormenting her day and night. Ye Huan forcefully lifts her chin and tells her that she'll be his plaything for the rest of her life. In the end, when her revenge fails, the heroine's devoted admirers band together to hunt her down and grind her bones to dust. Only after entering the story does she gradually realize that she hasn't truly transmigrated into a book. All of this is a trap set for her by Heaven. Later, Yan Chu tears up the script that the thieving heavens wrote for her, removes her bloodied lower jawbone and flings it at Ye Huan's face. She goes into overachiever mode, carrying a Gatling gun over her left shoulder and wielding a broadsword in her right hand, mowing down every love-struck fool who stands in the way of her cultivation.
