Yan Liao was originally the coldest judge of the underworld, but Miao Ye was a wild ghost wandering in the world of the underworld, tied to a life-and-death line due to an accident. When Yan Liao was ordered to arrest Miao Ye, he found among the corpses of Yin soldiers that the other party actually held the "soul-breaking thunder" that could explode the book of reincarnation - it was a relic of the ancient gods who wiped out the underworld. A pursuit turned into a violent counterattack. Yan Liao detonated thunder and fire with his own hands. The seven layers of the underworld collapsed, the souls of the dead soared into the sky, and all ten halls of Yama were lost. Now he has become a wanted criminal, and Miao Ye said with a smile: "What you are blowing up is not the underworld, but the rules of cannibalism." The two traveled through the rift of Yin and Yang in the bloody wind, while avoiding pursuit and killing, while uncovering the truth about the thousand-year decay of the underworld.
