Chronicles of the Yin-Yang Courier Station

In a world where the realms of yin and yang exist side by side, countless checkpoints link the mortal world and the underworld. The postmasters stationed at these checkpoints guard them and maintain order between the two realms. Taoism has been passed down for millennia and encompasses many sects, some of whose unscrupulous members seek to control both realms through Taoist arts. The protagonist, Pu Jiumin, was an intelligent technology project manager in the mortal world. By a stroke of fate, he entered the Daoist sect and eventually became a checkpoint guardian serving as postmaster between the mortal world and the underworld. He navigates both realms, resolves all kinds of supernatural incidents, and maintains the balance between them.
