Five hundred years ago, Yang Fan, the future head of the Sanqing Palace, stepped into the air and unexpectedly arrived in the modern era where spiritual energy is sparse. She originally wanted to rely on fortune-telling to make money and return home to lie flat, but by a twist of fate, she inherited a mysterious post station that only opened late at night. At 11:00 PM, an endless line of "guests" queued outside. The express delivery was only received and not sent, and negative reviews could reach the netherworld directly. What is even stranger is that the merit left behind by her uncle, the abnormal spiritual energy in the village, and the continuously appearing familiar traces are all pointing to a secret that has been forgotten for a long time.
