After the butterfly demon incident, the martial arts world is still tense. The situation in Fusang is chaotic. The emperor is worried that ambitious people are colluding with the powerful people in the Song Dynasty to subvert the two countries, so he sends Bao Zheng to continue to investigate the case. The Wangyan Sect is suddenly attacked by the ice demon, Ling Tianchuan and his disciples are killed one after another, and the martial arts world is once again in a bloody storm. Bao Zheng believes that this case is exactly the same as the butterfly demon incident, but it is more complicated and bizarre. In order to avenge his father's murder, Ling Xiao has to continue to rely on Bao Zheng's power to find the truth. The news of Ling Tianchuan's death shocked the other two major forces, the Xuanhuo Sect and the Miying League, and they began to plan how to compete for the throne of the leader.
