After Grandpa Was Buried, I Took over the Underworld Registration Office

[Folklore suspense + underworld registration + unit mystery + rule reasoning + no system + high energy throughout] On the seventh day after his grandfather was buried, Chen Sui'an received an urgent letter from the same city signed by his grandfather. Inside the package was a wedding and funeral application: the bride had been dead for sixty-seven years, and the groom's name was written on it. The case cannot be closed before the rooster crows, and the person handling the case has to marry the deceased. From that night on, the paper horse shop that had been closed for many years was relisted. There are weddings and funerals in mountain villages, and the names of living people are disappearing from the genealogy; ancient temples are forbidden to speak, and a wrong name will be left behind for the deceased; late-night ferry tickets are only sold to people who have fallen into the water; in a century-old house, the waker must find the person who really deserves to cry within seven days... There are no ghost-killing upgrades here, and not a single rule that can be smashed by brute force. All Chen Sui'an can do is check old files, question parties, identify relationships, verify contracts, and then use his name to vouch for unjust cases one after another. But he gradually discovered that the most terrifying thing was never "violators die". But everyone said: You volunteer.
