Su Wan, the young master of the Chixiao Kingdom, witnessed his father being killed by the Mist Blade at the Blood Moon Ceremony. His right eye awakened the "Eternal Calamity Eye" that can see through the weaknesses of all things, but he was reduced to a useless person because his meridians could not store energy. When he held the ancestral evil-blade Mirage Knife, the liquid silver mist actually began to erode the bones - this evil knife that needed to devour the owner's flesh and blood to grow contained the terrifying conspiracy of Mist Sea Shen Yinge to subvert Jiuzhou. The young man who was cursed with scarlet eyes used his soulless body to hold a sword and cut a bloody path in the torrential rain that caused the collapse of the dynasty. However, he found that every time he unlocked the seal, he would become inhuman and mutate. When the master of Chen Yin Pavilion held out a puppet with the same appearance as his, Xiao Jin finally understood: the most deadly fog blade had pierced his heart sixteen years ago.
