Qin Yun, the daughter of an archeology professor and the deputy chief of the police, lives up to her elegant and delicate name and slender figure, with a strong character. Never one to give in, she understood through this five-year experience that she was so powerless whether it was the archeology she loved or the cultural relic dealers she hated.
Lu Lin has a character that seems to have no edge at first glance, but people who come into contact with him will eventually be impressed by his sense of security. At least Qin Yun's once proud heart has voluntarily surrendered on the edge of life and death again and again.
During her undercover days, Qin Yun didn't know what would happen to her without Lu Lin's help.
