In order to avenge the death of her mother, Bai Wan'er married her sister Bai Jinqiu to Huo Jingxuan, who was rumored to be disfigured and critically ill. On the day of the wedding, she pretended to be cowardly, but in fact she was the "Ghost-faced Guanyin", a miracle doctor with the power to control snakes and detoxify. Huo Jingxuan also hid his identity, pretending to be disfigured and sick, but in fact he was secretly tracking down the Nantian Sect who killed his mother and the mole in his family. The two met for the first time as newlyweds and tested each other. Bai Wan'er secretly healed the poisoned Huo Jingxuan, but she didn't know that he was the long-lost grandson of her grandparents who she had been looking for.
