Lin Mo is a temporary employee of the Underworld stationed in the mortal realm. His daily duties include helping ghosts pass on, settling disputes between neighbors, and dealing with absurd performance targets. To secure a permanent position, he comes up with “Dream-Visit Annual Passes” and “Emotional Management Classes for Vengeful Ghosts,” and even introduces an Underworld membership program. His results are so outstanding that the King of Hell summons him for a meeting. But instead, the King pulls out his phone: “I hear VIPs get priority reincarnation? Sign me up for a lifetime premium membership.” From then on, Lin Mo is forced to navigate absurd evaluations and the bureaucracy of the afterlife, overturn wrongful verdicts for ghosts who have suffered for centuries, and fight corruption in the System. From a lowly wage slave, he rises to become the one who breaks the deadlock and reforms the Underworld. This is the story of an ordinary man who uses dark humor and quiet courage to carve out a little warmth in a world of cold rules, and ultimately rewrite them.
