Youdu: I Suppress Hundreds of Ghosts in the Underworld

Lu Chen is an old book restorer who was raised by his grandfather who ran a paper shop. When he was twenty-four years old, he encountered a red funeral procession without footprints on his way back to his hometown for a funeral. When he woke up again, he was already lying in a black coffin covered with corpse-killing charms. Outside the coffin is not the human world, but an ancient city where there is never any dawn - Youdu. The old man in charge of picking up the souls of the dead told him that as long as he abides by the taboos in the city and survives seven nights in the inn, he will be qualified to enter reincarnation.
