Shen Jin, a poor boy who was publicly humiliated by his daughter, showed his right to bid in a transnational black market auction overnight, silencing the entire audience. When he and Xie Zhao, who has the blood of an ancient witch, were forced to join forces to uncover the bloody secret history behind each ancient artifact, they discovered that the ridicule was just the first game played by fate.

Ah Jiu's cry, Lu Heng's prosthetic limb, Zhou Yanqiu's smile, Bai Ji's whisper - every shadow is urging them to move towards the real end: when the blood crystal box is opened, who is the real successor?
