Episode 4 recap: Yin Ruoshui changed her name to Qin Ruoyao.

Under Lin Cangwu's careful treatment, Yin Ruoshui gradually regained consciousness. She learned that she was in Liaocheng, still within the territory of the Southern Frontier Kingdom. Yin Ruoshui felt panicked, but with Lin Cangwu's reassurance, she gradually calmed down. When she found out that it was Lin Cangwu who saved her, Yin Ruoshui was extremely grateful. Due to the injuries on her face, Lin Cangwu had to perform surgery to treat her.

After Lin Cangwu removed the tape from Yin Ruoshui's face, her appearance changed significantly. She looked quite different from before, almost like a different person. Lin Cangwu asked her name, but Yin Ruoshui didn't dare to tell the truth. Instead, she told him that her name was Qin Ruoyao. Lin Cangwu allowed her to stay in the mansion and had a maid accompany her for a walk. At the same time, he informed her about the Lin family. It turned out that Lin Cangwu was adopted by General Lin of Liaocheng and had an elder sister named Miss Lin. General Lin loved Lin Cangwu dearly and even passed on the title of General to him. Lin Cangwu lived up to expectations and achieved great military accomplishments in the recent battle against the Yin Kingdom, for which he was praised by the emperor.

Upon hearing this, Yin Ruoshui was shocked. At that moment, they encountered Miss Lin. Miss Lin was suspicious of Qin Ruoyao's identity, but since she was a friend of Lin Cangwu, she suggested that she stay in the mansion for a while. Yin Ruoshui learned that there was an epidemic in the territory of Liaocheng and offered to use her medical knowledge to help the affected people. Lin Cangwu gladly agreed to her proposal.
