Ran Busheng traveled to the world of the dead due to an accident - a humorous, chaotic and ghostly world full of strange rules. Accompanied by strange partners such as Sister Lingling, Sensen Bai, and Bajie Coffin, he had to participate in the survival game, puzzle adventure, work internship, and Pluto's perverted mission in the world of the dead. Each volume advances a new undead crisis and growth node. It not only contains humorous adventures, but also involves themes such as "life and death", "self", "friendship" and "redemption". In the end, Ran Busui and his party found the ultimate secret of the world of the dead under the arrangement of Pluto, and achieved self-salvation. The return to the underworld is not yet over, and the ending is warm and healing.
