I recommend 'The Time of Qin and the Rain of the Moon' and 'Qing Ding Feng Hua' to you. The first book was a doujinshi derivative light novel. The female protagonist transmigrated in the Qin Dynasty and met the sage of conspiracy, Zhang Liang. Together, they explored the supernatural power and unimaginable secrets. The second book was an ancient romance novel. The female lead, Yu Shang, and her best friend traveled to ancient times and happened to pengci Ao Huang. The story between the two was fascinating, and the ending was He. I hope you like my personal recommendation.
