Zhang Wuji
Zhou Zhiruo reads the "Nine Yin Manual" and masters a quick-learning and "unorthodox" version of the skills detailed in the manual. As the story progresses, she develops a closer relationship with Zhang Wuji, until she decides to break her oath and marry him. However, Zhao Min shows up and disrupts the wedding. Zhou Zhiruo attacks Zhao Min in anger but Zhang Wuji intervenes and stops her. Zhou Zhiruo feels that Zhang Wuji has betrayed her love, and begins to see him and Zhao Min as her sworn enemies. She pretends to marry Song Qingshu of the Wudang Sect, who has a crush on her, and passes him the "Nine Yin Manual" and tells him to learn the skills and use them to defeat Zhang Wuji.
