Believing he has finally won, Zhou Kui confesses that he murdered Wang Ruo Jin after she discovered his true identity. Forced to surrender the Red Armor Army's military seal, Li Shu appears to give in, but Zhou Ruo Xi suddenly turns on Zhou Kui and stabs him to avenge her mother. Fu Wei then reveals that she is Zhou Ruo Xi from three years in the future, while Liang Feng successfully prevents Zhou Kui's final plan by destroying the explosives hidden throughout Qingzhou. Driven to desperation, Zhou Kui launches one last attack before Li Yan kills him. Ling Lan then attempts to avenge her master by shooting Fu Wei, but Li Yan shields her with his own body. As Fu Wei sacrifices herself to protect Li Yan, both are struck by arrows and collapse together in the snow, where Li Yan finally regains all the memories of their previous life. In the present day, Fu Wei finishes writing their story. At a cultural festival, she meets Li Shu and Zhou Ruo Yao before encountering a man who bears Li Yan's face. As they gaze at each other, it becomes clear that their bond has endured across lifetimes. (Source: Chinese = tvmao.com || Translation = KamilaRN at MyDramaList)
