This was the description of the plot in the book," The Evil Emperor Specially Spoils Older Concubines ". Let me recommend a novel similar to the one in the palace," Feng Qiu Huang." The story also takes place in the ancient palace. The female protagonist was demoted to a concubine's daughter and finally married to the empress. In the middle, there was a series of palace struggles and emotional entanglements. I hope you like my recommendation.😗
