I recommend "Little Ruffian Girl Traversing the Deep Palace 2: Only Being an Empress, Not a Concubine". This is an ancient romance novel with the female protagonist named Qian Duoduo. In the story, her hair was short, she was skilled in martial arts, she was open and bold, she was strong and difficult to tame, and she only wanted to be an empress and not a concubine. If you like novels that travel back in time, then this book is definitely suitable for you. I hope you like my recommendation, Mwah ~😗
