Fresh graduate {Zhao Lei} accidentally joined Shanhai Technology Company, but found out that the human resources department hid a secret - the fox demon HR can see through the truth, the tree spirit administration uses vines to check attendance, and the dragon turtle supervisor deducts his salary based on bad luck! The core business of this company is actually to help monsters integrate into human society: find night security guards for werewolves, and connect vampires with volunteers at blood donation stations. Zhao Lei's internship task is to deal with all kinds of outrageous monster workplace disputes: a werewolf who lost control and chewed up documents on a full-moon night, a vampire who was shoed because he refused to work overtime... When a koi carp with good luck comes to seek employment, its good luck causes the stock price to skyrocket, but it leads to a kidnapping villain. Zhao Lei was forced to join forces with fellow monsters, use illusions and vines to set up a trap, launch a fantasy rescue in an urban office building, and finally counterattack from a human intern to a dedicated communications specialist.
