At the end of the Dayin Dynasty, Yin and Yang were out of balance, the underworld collapsed, and ghosts walking at night became the norm. Zhong Yeming, the son of a watchman, was patrolling the streets on a cold night when he saw thousands of ghosts arrayed in formation and the ghost generals kowtow with their seals. On the spot, he awakened the bloodline of Pluto that had been dormant for thousands of years - it could summon Yin soldiers, command ghosts, and judge the remaining pages of the book of life and death. However, this force attracted the Heavenly Court's 'Fuxisi' and the remnants of the Underworld's 'Youdu Palace' to join forces to encircle and suppress him, treating him as an out-of-control 'abandoned piece' in the game between gods and demons. The main plot revolves around Zhong Yeming breaking the seal, gathering the Yin army, and recasting the law of the underworld: he must find out the truth about his bloodline, dismantle the controller of the gambling game, and rebuild the new order of Yin and Yang before divine punishment comes. On the way, he formed an alliance with the subjugated prince, subdued the rebellious ghost cultivator, and outsmarted Tianji Pavilion's deduction. In the end, he used himself as a sacrifice to burn the rules of the game to ashes and restart the six paths of reincarnation.
