Qing Jiao Wo Gui Chai Da Ren(2023)

After the long night, terror shall reign! Supernatural monsters descend upon the modern city! Common sense and rules of law are no more! Blood rains down on a peaceful campus, tombs crack open in the cemetery on the outskirts of town, and the slums are haunted by shadowy apparitions… In this dark and desperate world, there is a post office that only emerges at midnight, where a young man dressed in black can navigate these mysterious and terrifying places. The young man in black will become a legend, his stories passed around in secret by word-of-mouth, “He is the Great Lord of the Underworld!”
