Midnight in Jiangcheng is never peaceful. Crying in the depths of old alleys, strange shadows in office buildings, disappearances in river crossing tunnels - these strange events that are regarded as urban legends by ordinary people all point to a secret organization hidden under the neon lights: Night Travel God Agency.
Lin Feng, an ordinary college student who was on the verge of failing his exams, accidentally awakened the "Night Travel Seal" during a late-night adventure and was involved in the thousand-year dispute between Xuanmen and the Chaos Realm. When the chaotic demonic energy that covers the sky breaks through the underground seal, and when the underworld rebels and evil demons join forces to wreak havoc on the world, he holds the soul-suppressing bell in his hand and wears the Night Travel Seal on his body, and from then on he becomes the city's night watchman.
