From Temp Worker in the Underworld to Supreme Ruler of the Three Realms

【Underworld labor dispatch】+【A trio of human, ghost, and immortal】+【Rising to become supreme】+【Episodic tearjerkers】+【A working stiff of a ghost constable】+【Just going through the motions~】 Su Wang is the lowest-ranking dispatched ghost constable in the Underworld, employee number 130. She does the hardest work, earns the lowest pay, and has no hope of becoming a permanent employee. She has fragments of memories from nine hundred years of reincarnation, but bowl after bowl of Meng Po's soup has washed them all away, leaving only a broken jade pendant of unknown origin. Then an assignment to fulfill a final wish is triggered by accident. The authority, normally reserved for permanent employees, lands in the hands of a dispatched worker like her. She helps an old lady catch her cat, assists a programmer in investigating a murder, and helps an elderly undertaker finish his final stitch... Behind every final wish lies an unfulfilled obsession of a departed soul. As she completes one assignment after another, she discovers that the Underworld King personally locked her file away in a hidden archive. Ancient divine script is carved into the broken jade pendant, and hidden in the nine hundred years she has forgotten is a name that even Wu Zetian feared. From the lowliest dispatched worker to the supreme ruler of the Three Realms, she has walked this path through nine hundred lifetimes.
