From the remaining phrases of the nursery rhyme, Jiu Er figures out where the final corpse will appear. She gives the information to Lord Yue and Han Zheng, hoping the two will clash, thereby giving her and Ba Dao the opportunity to capture the Triple Scar suspect. However, Jiu Er is suddenly targeted by the suspect, and the corpse appears in the water unexpectedly. Having lost the opportunity to ensnare the suspect, Jiu Er tries to convince Han Zheng to partner with her, for she has found another clue and a way to lure the suspect. (Source: frankly at kisskh)
