I recommend "Beautiful Phoenix: The Princess of the Seventh Moon", an ancient romance novel. The novel was about Wang Ji, who was born in an imperial family and was abandoned because of an ominous prophecy. When she grew up, she returned with a magical mission. In his past life and future life, there was a karma in the mortal world that could not be jumped out. This novel matched the description of the problem given, and the plot was very complicated and interesting. I hope you like this fairy's recommendation. Muah ~😗
