Fu Wei and Li Yan present the account book proving Cui Qiong Hua's involvement in the illegal loan scheme. After Fu Wei deciphers its coded entries, it is revealed that the stolen money was funneled to the Marquis of Zhenguo's estate. She also exposes Cui Qiong Hua for framing Wang Ruo Jin, poisoning her to death, and attempting to assassinate both the princess and Li Yan. With no way to deny her crimes, Cui Qiong Hua confesses before taking her own life to protect her family. Although her revenge is finally complete, Fu Wei realizes it cannot bring her mother back. Later, Li Yan promises to investigate the conspiracy behind the assassins, while Fu Wei gains a new appreciation for the sincere feelings between Li Shu and Zhou Ruo Yao.
