I recommend the following novels that have a similar style to Legend of Zhen Huan: " A Song of Lament "," The Empress Dowager's System "," Cold Moon in the Qing Palace "," Biography of the Imperial Consort Wenxi in the Qing Palace ", and " The Reborn Empress is a Black Lotus Flower." They all had elements such as palace fights and harem battles, and the female lead was also very capable. I hope you like my recommendation.😗
