Mental Hospital? No, This Is a Demon Breeding Base

Lin Shen wears a book and becomes the director of a mental hospital with a debt of five million. Lin Shen is driven to collapse by the sky-high electricity bill as soon as he opens his eyes. Fortunately, he is bound to the "Absolute Sanity System" - which can modify the Cthulhu monsters into everyday things: the eyeballs with the size of millstones are lost owls, the abyss succubus is a disheveled head nurse, the nuclear explosion devil is an old man with a fever, and the army of deep divers is actually a "seafood gift package". In order to pay off his debts, he was stingy to the extreme: deducting the wages of S-class succubi to compensate for violations, using isatis root as a "high-energy coolant" to suppress nuclear explosions, letting cultists grow potatoes to pay off debts, and using abyssal torture instruments as massage chairs for employees. It was clear that he was unconsciously crushing the supernatural, but he was transformed by all the agents of the Anomaly Investigation Bureau and the cult bishop, mistaking him for the "incarnation of the ancient god" and the "rule master". This mental hospital is not a sanatorium at all, but an anchor point to the abyss. The patients are all sealed demon species. Even the children with graffiti in the corner are cubs of ancient gods who can rewrite dimensions. While Lin Shen was planning carefully to generate income, he was forced to be the "gatekeeper of the abyss." It wasn't until the deep-sea bill arrived and the space crack exploded that he discovered that the system was not a golden finger, but a sealing contract, and he, the "poor dean," had long since become the key to maintaining the balance of the world. Suspenseful imagination + weird rules + Cthulhu carnival, watch how the stingy dean uses daily operations to tame the devil, and in the outrageous plot where all the members are transformed, he can pay off his debts and protect the world at the same time!
