This character... Gu Jiu is a genius after all, so why did he time-travel in the body of this scumbag and good-for-nothing young lady Gu Beiyan? ! But it doesn't matter. With the system artifact in hand, sex change at will is no longer a dream. Gu Jiu, who had transformed into a man, met the Ninth Prince, Jiang Qiancheng by chance. She was mistakenly taken to Sheng'an Kingdom, and met the Sheng'an Prince Mu Yan in her daughter's body. No, there must be a mistake somewhere. I, Gu Jiu, will definitely make peach blossoms bloom. But, if this is open, why are they all men? Random sex change, slutty guard × fake white flower, domineering and tsundere attack
