A Qi Refining Cultivator Working as an Assistant in Another World

Su Qingxuan is an ordinary auxiliary police officer in Jixiang District, Haizhou City. By day, he stands guard, writes tickets, and mediates neighborhood disputes. At night, he has to sneak in overtime, dealing with things that should never appear in the mortal world.

As the last heir of the Zhenwu Demon-Suppressing lineage, he carries a golden-page Daoist scripture against his chest and keeps peach talismans and a Divine Heaven Demon-Subduing Brick in his pockets. He practices the lowest level, Qi Refining, but takes on the deadliest jobs: encountering wandering spirits on the night shift, purging yin fiends from hospitals, locking down a flood dragon with the Big Dipper during a typhoon, and smiting evil with the Five Thunders in Qingshi Town... Along the way, he rescues his colleague Zhang Meng from evil spirits, draws his fiery partner Lin Xi into a substitution calamity formation, and sets his newly discovered cousin Su Xiaoyuan on the path of Zhong Kui's demon-slaying arts.

As spiritual qi revival begins and spiritual ley lines are about to emerge, the official covert agency, the Anomalous Affairs Bureau, comes knocking. Deep in an ancient cave, Fuyue, an ancient bloodline-bearing dragon turtle that carries a mountain on its back, recognizes him as one of its own. Four people and a turtle punch in as usual by day, then uphold Heaven's justice by night.
