Please recommend a novel where the protagonist has two identities. One of the identities must be the strongest, such as the sword dance of the elf.

I recommend 'The Phoenix Battles The Land' to you. The protagonist of this Xianxia-Wuxia romance novel had a double identity. One was the former future courtesan, and the other was a current cultivation expert. She continued to grow as she cultivated and eventually became an existence like a phoenix, unstoppable. I hope you like this fairy's recommendation. Muah ~😗
