In his previous life, Han Mo was the youngest judge in the Underworld, in charge of the Book of Life and Death, and judged all ghosts. However, he was plotted by his close men and subordinates, and the "Netherworld Pearl" forged with thousands of years of cultivation was plotted against him, and his soul was scattered in the Nine Nether Purgatory. In this life, he was reborn as an ordinary college student in modern society. On the surface, he is humorous, but in reality he is deep-minded. He also carries the "Netherworld Bead" that can defy heaven and change fate - it can swallow Yin Qi, control spiritual bodies, and exercise the power of the Yin Division. This is the end of the Dharma era when spiritual energy is revived, ghosts are rampant, and ghosts and monsters are lurking in the shadows of the city. All the great sects and aristocratic families are competing for resources. They appear to be sanctimonious on the surface, but secretly they are just trying to get away with it. Han Mo discovered that the people who harmed him in his previous life were reborn with different identities in this life - some were leaders of aristocratic families, some were elders of Taoist sects, and some even infiltrated into the mysterious government department. They all carried the memories of their past lives and joined forces to set up a dragnet, trying to plunder his Youzhu again. "In this life, I am the hunter." Han Mo chuckled and opened the book of life and death in his hand. He will use the laws of the underworld to judge this backstab that spans thousands of years - let every evil person taste the consequences of his own actions. But when he gradually uncovered the truth, he found that things were far more complicated than he imagined: the origin of the Nether Pearl, the destruction of the Underworld, the seal deep in the Nine Netherworld... A bigger picture was waiting for him.
