Traveling Through Another World: the Original Body Asks to Be Taken Away

A certain college student accidentally complained about the cannon fodder in a bloody novel and was brought into the book. I thought he was the son of a villain boss, but he turned out to be a worker without a father. But why is this world different from what was promised: Where does the monster come from in a harmonious society? Why does this female ghost have no head? Why did the creatures in a certain mountain and sea escape? A certain ghost who didn't leave glanced at it and easily solved it with his fingers. That's it? That's it? You have the nerve to talk to me. Someone has a guilty conscience and the boss wants to take him away. This novel and its characters are purely fictitious.
