Echoes of the Self Episode 17

Zhou Kui reveals that he has known Fu Wei was impersonating the princess all along and demands that she either cooperate with his rebellion or die as the Zhou family's second daughter. Fu Wei realizes that Zhou Kui has been secretly raising funds, building an army, and colluding with foreign forces. She attempts to escape but is wounded before Liang Feng rescues her. After hearing everything, Li Yan suspects Zhou Kui is behind the conspiracy, while Fu Wei believes Li Shu is also involved. Refusing to condemn his brother without proof, Li Yan lures Li Shu to the Yan Prince's residence to uncover the truth. Once Fu Wei explains everything, Li Shu realizes he has been deceived and agrees to join forces with them. He also discovers that Fu Wei is not Zhou Ruo Xi. As the three unite against their common enemy, Li Yan promises to protect Fu Wei. Meanwhile, Zhou Ruo Xi secretly orders a search for the missing Li Shu while keeping his disappearance hidden from Zhou Kui. (Source: Chinese = tvmao.com || Translation = KamilaRN at kisskh)
