After the eternal night, terror awakes. In the wasteland of ten li, eerie songs ring. The old man searching for his arms, the headless baby… They ceaselessly reattach their own bodies, erupting even more horrifying auras. In the barrens, even a severed hand can destroy the heavens and extinguish the earth. In this hopeless, despairing environment, a vaguely visible post office… A mysterious young man, a postal carriage traveling through the void… One blood-red letter after another, becoming a taboo on people’s lips… PS: No or single female lead (Don’t wildly guess, at least not Zhou Han)
