Ye Wujin, who had the emperor's bones ripped out by his relatives and thrown into the Jiuyou Corpse Cave, devoured the demon lord's remnant soul and used the demon bones to reshape his body. The moment he stepped out of the corpse cave, the three worlds were shocked. Su Lishuang, the female gravekeeper in the corpse cave, secretly guides him in order to resurrect his mother; Lord Red Nightmare wants to use his body to reshape the devil, and the Bone Scholar glimpses the beginning of the collapse of heaven in his lifeline. When the emperor's blood and demon bones coexist, and when ancient sacrifices awaken from the corpse cave, who is the real demon? Who is worthy of being called God?
