So I have been trying to find a novel that wasn't complete and I forgot to mark down the title. It began with the MC, a female with the surname Feng(If I remember correctly) whose cultivation/destiny had been stolen by a girl who had a similar? aspect of the Phoenix or something. She was then declared a waste and she, her mentally ill mother, and younger brother were cast out into a town on the border or something?She also had a master in a secret space who was injured and the story really starts with her trying to get a fruit that, coincidentally the male lead also wants and he's her fiance and he hasn't allowed the betrothal to be dissolved for reasons? I can't seem to find it anywhere.
You're looking for Godly Empress Doctor, which was a victim of MistyCloud's Qidian purge a few months back. Not sure if it's being continued on Webnovel. Edit: It doesn't appear to be. Looks like it's in limbo and you're out of luck.
