The end of all worlds is Netherworld. At first, hundreds of ghosts were rampant and people in the human world were living in dire straits. The Emperor of Heaven was furious, so he sent the god Ye Lan to govern Netherworld. After taking over Fengdu, the god Yelan set up ten palaces of Yama, and gave ten magical weapons to seal ghosts and ensure peace and stability in the two realms and orderly reincarnation.
Unexpectedly, the sacred artifact "Jiuyou Xuanhua Lu" used by the Nine Nether Palaces to seal ghosts was opened by someone when Wen Yuwan's flower Gu was active. The ghosts were flowing into the human world. The Lord of the Netherworld was furious and sent Wen Yuwan to the human world to recall the ghosts. As he recalled the ghosts, Wen Yuwan discovered that the artifacts were opened. The person who caused the ghosts to wander into the world in "Nine Netherworld Xuanhua Lu" was Yan Lingchuan, whom he gradually came to like and trust. The two gradually developed a rift. Later, the two kings of the West competed for the crown prince. Wen Yuwan was arrested. Yan Lingchuan arrived in time and expressed his feelings. The two reconciled and formally established their relationship.
Then the two of them jointly recalled the ghosts in "Nine Netherworld Xuanhua Lu" and experienced a series of stories of crisis and joy where life and death coexisted.
One sentence summary: Wen Yuwan, the princess of the Netherworld Ninth Palace, went to the human world to recall the ghosts in "Nine Netherworld Xuanhua Lu" and fell in love with Yan Lingchuan, the fallen angel of the West.
