I, the NPC, Change the Ending in the Background

Let me first state that the content of the story is fictitious, please do not imitate it. An immersive horror game called "Infinite Corridor" is popular all over the world, in which players experience countless horror replicas just to escape. However, no one knows that the game has already gotten out of control and has become a real hell that swallows consciousness. No one knows that the seemingly ordinary librarian NPC in the copy is the former chief planner of the game - Lu Ming.
