Echoes of the Self Episode 18

Li Shu blocks Zhou Kui's supply route after learning of his rebellion and reconciles with Fu Wei, who decides to let go of the resentment from her previous life so they can work together. To deceive Zhou Kui, Li Shu pretends to be consumed by grief over Zhou Ruo Yao, convincing Zhou Kui to trust him. Believing his plan is succeeding, Zhou Kui orders Zhou Ruo Xi to secretly poison Li Shu with a drug that will keep him under his control. Fu Wei makes one last attempt to persuade Zhou Ruo Xi to turn against Zhou Kui, but she refuses despite realizing their lives are mysteriously linked. Soon after, Fu Wei and Li Yan finally marry. Although Li Yan's health continues to decline because they now share the same fate, he has no regrets. Just as the couple is about to complete their wedding ceremony, an unexpected voice interrupts the celebration. (Source: Chinese = tvmao.com || Translation = KamilaRN at MyDramaList)
