In the fifth year of Yongle, the emperor wanted to rectify his title and secretly ordered the formation of the Night Walkers, which was the dirtiest knife in the emperor's hand. In the twelfth year of Yongle, Chen Chao, the chief of the Night Walkers, failed in his mission, and thirteen of his Night Walkers died. Chen Chao was seriously injured and on the verge of death. All the people he protected were slaughtered, except for one daughter, Pei Nian. Chen Chao withdrew from the night traveler and took Pei Nian away to stay with him. The two hid in Beijing and lived peacefully for ten years. However, a strange corpse involved Chen Chao and Pei Nian in a life and death crisis.
