Lin Si, codenamed "Ming Deng", is the youngest monster captain of the Great Xia Night Watch. However, he took the initiative to apply for transfer to the "Daxia Mental Hospital" - a top-secret restricted area that houses awakened "gods" and weird "mysteries". There are no patients here, only nameless things that bend the rules.
As a new caregiver, Lin Si's daily job is to have fatal interactions with these beings. From the regular light group who loves "Truth and Dare" to more unfathomable containment projects, every contact is a game between reason and madness.
Here, common sense is poison and regulations are the only driftwood. Lin Si steps into the darkness calmly. He will face the abyss, clarify the rules, and try to uncover the twisted truth of the world from these imprisoned "gods".
