In fact, Shangguan Ru had made her move before Slave Huan's return, and she had already tried all sorts of methods to entice her twin brother to enter the South City.
Her first option was to make use of Xu Yanwei, who Shangguan Fei was very fond of. As she was also under the protection of Slave Huan, she would be the perfect person to serve as a bridge between both camps and for convincing him to enter the South City.
However, she quickly killed off the idea because Xu Yanwei had informed her that the Ninth Young Master had already replaced her with another woman. Xu Yanwei was devastated as she had, yet again, failed in her lifelong mission to marry into a rich family.
