It seems that you are very interested in the book, Heavenly Court of Yi. If you like this type of scheming female protagonist, then I recommend you to read "Hua Qiangu". This is a very interesting ancient romance novel. It is based on the sadistic love story between the female protagonist Hua Qiangu and the male protagonist named Bai Zihua. It is mixed with elements such as Xianxia and fantasy. It is full of suspense and reversal. If you want to know more about novels like chess and marriage, I can also recommend them to you. Song in the Cloud, Twelve Hours in Chang 'an, and The Legend of Ruyi are all good choices. I hope you like my recommendation, Mwah ~😗
