Shangguan Ru allowed her killers to act freely by leveraging on her authority.
Gu Shenwei realized that he made a wise move of not killing Shangguan Ru at that point in time as this was the best opportunity to act freely without the need to bear much responsibility.
In the eyes of outsiders, Stone Castle's Tenth Young Master seemed to become stranger, tougher and more ruthless as though she wanted to take over the entire South City. However, only three killers knew the truth. Shangguan Ru became fearful and she was unable to overcome this ordeal. On some occasions, she wanted to stay away from killing people. On other occasions, she became overcome with ambition and wanted to do something extraordinary. This was the main reason why she stayed in South City even though she did not do much there.
