I recommend "The First Lady's Snake and Scorpion". This is an ancient romance novel written by the author, the swordsman. The protagonist was a trump card killer, but she eventually died at the hands of her superior and was reborn as the most inconspicuous Di daughter of the Prime Minister's residence. In this environment, when she faced her gentle and virtuous sister, the entire Prime Minister's residence was stirred up by her. If you like novels about female assassins traveling through time, you can't miss this book! I hope you like my recommendation, Mwah ~😗
