I recommend the following two time-travel novels about Shangguan Wan 'er to you, Return to Ancient Times and Be a Sage, and Wantang. Among them,"Return to Ancient Times as a Sage" was a sci-fi time-travel novel, telling the story of Shangguan Wan 'er traveling to ancient times to become a Great Sage Master, while "Wan Tang" was an ancient romance novel, telling the story of Yang Xiao traveling to become Shangguan Wan' er and surviving in the Tang Dynasty palace. I hope you like these recommendations. If you want to know more, you can tell me anytime ~
