I recommend " Beautiful Spirit Controlling Concubine: The Preceptor Begging You to Put Her Down ". The male lead is called Xuanyuan, the Preceptor of the Nalan Royal Family. The female lead is Ling Qingyan. The Eighth Prince of the Nalan Royal Family also likes her and her younger sister, Nalan. The story had elements such as demons, ghosts, immortals, and the six worlds. It was a very interesting journey through time. I hope you like my recommendation.
