Li Lan, the "thorn-headed god of death" in the underworld, was sent to earth for accidentally tearing up Yama's vacation slip. He traveled across China with a "Duohe Book" that can record and trace the origin of his crimes - this spiritual instrument can not only collect souls, but also record work points in the underworld, and can occasionally be used to cook instant noodles.
He has the goal of "reinstatement with full quota", but he always plays tricks when exterminating demons: holding "confessional live broadcast" for the turbid spirits to atone for their sins, questioning the masterminds behind the scenes with cold jokes from the underworld, and bravely resisting the turbid miasma in the world to protect the people around him. From uncovering a human-eating spirit with "obsession for perfection" in the mirror of the West Lake, to solving the mystery of the seal of the air-eating spirit in the Luoyang bone china kiln, to tracking down the memory thief on the Chongqing foggy light rail, there are clues to the "contamination of the boundary gap" and the "secret secret of the dragon bone" hidden behind the strange cases in each city.
Shen Qingyue, the aloof successor of the Gate Keeper, Su Wanqing, the restorer who can talk to antiquities, Qin Yutong, the dashing support on the water, and Ye Ziling, a medical student who can make Qingzhuoxiang. The four heroines became attached to him because of the case, and they went from complaining about each other to fighting side by side. When the Xuanyin Sect gathered all the dragon bones and wanted to use the dragon veins of the Forbidden City to tear the gap between the boundaries, Li Lan discovered that this "journey to the mortal world" had long been the fate of guarding the spiritual veins of China.
On one side is the passion for catching ghosts and solving crimes, on the other side is the comedy of gags, and the warm exchanges between the harem group - let's see how this God of Death, who is both vengeful and protective of his shortcomings, uses a book to escape disaster and fill the neon lights of the city with his own Chinese record of slaying demons.
