My Disciple Has Fallen to the Demonic Path Again and Again

Bai Xi transmigrates into a cultivation novel full of angsty romance as its tragic heroine. She pines after the male lead for ten lifetimes without ever winning his heart. The heart-wrenching torment along the way goes without saying, and in the end she falls to demonic corruption and is executed. The tenth lifetime is the worst of all. Not only is her face disfigured and her voice poisoned away, but the number one powerhouse in the cultivation world, Ancestor Wuji, will turn her to dust in an instant, destroying her body and soul! What the hell kind of heroine is this? This is clearly the plot and fate of a supporting character. Thinking of the ending, then looking at Ancestor Wuji, who is terrifyingly ruthless yet so handsome he could split the sky, Bai Xi decides: With a master this powerful and good-looking, wouldn't it be great to cling to his leg and cultivate the path to immortality like a good girl? But then... She has the time of her life cultivating, only to be dragged onto the demonic path by her master, Ancestor Wuji?!! Wait, isn't something wrong with this plot? A dark, eerie aura curls around her ears. Her master lifts her chin, his voice chilling: "Good disciple, are you willing to cultivate spiritually with your master?" Bai Xi is nearly scared to death. Damn it, the original plot set me up. This is not how things were supposed to go at all. Can someone tell her why this incredibly impressive master is making a move on her? Theme: I wish to guide you to immortality, yet you guide me into demonic corruption.
