The end of the world is coming, and all kinds of strange things are rampant. Lin Zhou, who inherited the blood of the judge, did not choose to fight and kill, but started a unique career as a "ghost hero". He transformed his ancestral "guarded house" into a safe house and rented it out to powerful ghosts who also sought refuge in the apocalypse. Faced with "prickly" tenants such as Kayako, Sadako, and Xiakou Nu, Lin Zhou, holding the book of life and death and the judge's pen, turned the crisis into a business opportunity with the tough terms of "one deposit, three deposits, and a monthly rent of 300 million net coins." In the daily life where horror and comedy coexist, he not only obtains apocalyptic survival capital by collecting rents, but also begins to plan to use his own advantages and "customer resources" to launch a series of unbelievable businesses such as "Underworld Express" and "Grudge Recycling". He is determined to open up an alternative "dark world" business empire in this desperate wasteland.
