29-Year-old Su Wan is the seventh-generation descendant of the family's old funeral shop "Palace of Rebirth". Her daily job is to write elegiac couplets, sort out the remains, and send funerals to the deceased. She is calm and sober, and is used to facing the world with an undertaker's view of life and death.
During a late-night wake, Su Wan was grabbed by the deceased female teacher's arm, and the corpse left blood marks on her palm. At the same time, a strange interface called the "Underworld Civil Servant Examination System" unfolded in her mind. The system told her: After completing the KPI (resolving the obsession with the deceased) and accumulating enough merit points, she could apply for the civil service examination in the underworld; if she failed in the task, her life span would be lost.
Su Wan relied on the professional intuition of an elegiac couplet writer to "translate" clues from the dungeon world into metaphors in the elegiac couplet, and escaped again and again in the strange rules and stories.
From the interview at the funeral home to the disappearance case in Apartment 404, from the Night Walk of Ghosts in the City God's Temple to the Mass Tomb in the City of Unexpected Deaths, Su Wan's abilities continued to evolve - she discovered that the elegiac couplets she wrote could not only read memories, but also rewrite the ending.
And as the journey of "taking the public exam" deepens, a huge secret emerges: the underworld system is not created by gods, but the order of time and space that an ancient "elegy" exchanged for his life. Su Wan is the reincarnation of the ancient elegy singer.
The real underworld system is collapsing, and the copy world is invading the human world. Su Wan had to make a choice between death and rebirth: to complete the system's ultimate mission and become the new guardian of order; or to write the last elegiac note with his own hands for this dying world of reincarnation.
Intention: Use the elegiac couplet as a boat to ferry others and yourself. Life and death are impermanent, but good intentions last forever.
