Library

When I was in college, I was organizing books for the teacher who managed the library on the weekends. I accidentally found a book that recorded a method to summon the Demon King. In a mood of inquiry and suspicion, I privately took the book to the basement of the library, where I activated the teleportation array according to the method in the book. "Um... Hello, are you the demon king I summoned?" I looked a little embarrassed at the strange creature in front of me. "What summons? How dare you invade that lord's castle? Capture him!" "What? What castle? Tell me clearly. Hey, tell me what you have to say. If you touch me again, I will call the police." It wasn't until I was caught and taken away by those guys that I noticed that the place I was in was not the basement of the school library. "What's going on?" I was a little confused. They beat me up every day and asked me where I came from. I told them so many times, but they didn't believe me. I really came here because I failed to summon the Demon King. "You were waiting for me. You beat me like this every day. You were waiting for me to come out and you had to destroy your lair!" Although I say so, can I really defeat the Demon King?
