It's Very Appropriate to Engage in Underworld Operations in the Underworld Game, Right?

Welcome to the super weird game. [Enter the copy: Blue Sky Kindergarten] [Your mission is: end the source of pollution] [Your neighbors include: the sunny maid with long hair covering her face, the powerful transvestite Goblin, the timid mouse wearing a wolfskin cloak...] [Your classmates include: a beastly boss who doesn't follow common sense, a big man-eating cat that walks upright, a perverted old man with bat wings...] Xu Ze, as a salesman who died under mysterious circumstances, luckily got a game that allowed him to be reborn as a human after clearing all copies. For this, he only had to pay a small price: Search the intestines and scrape the belly (Physics), dig out the heart and lungs (Physics), change the mind (Physics), and be a new person (Physics)
