Following the aftermath of the Taipingtao Revolution, China remains engulfed in a relentless war as remnants of the defeated rebellion persist in their resistance. The tragic legacy of the conflict emerges in the form of malevolent creatures known as the 'wangliang,' born from the deep well of sorrow and death. To combat this threat, immortal beings called the 'Tianyuan' bestow the title of 'Hunters' upon chosen individuals, aided by the 'Guizhan'—specialists capable of harnessing miasma to transform into demons, crucial in battling the wangliang. After a disastrous event leads to the disbandment of the Sixth Hunter Unit, three promising Hunters—Ji Ying, Qiao Xun, and Yan Ding—are tasked with rebuilding the team. Unexpectedly, the young Guizhan Xiao Ling, linked to the unit's past tragedy, is also assigned to join them. Amidst inner conflicts and mysteries, the reformed squad must unite their unique powers to confront the common foe and secure victory.
