Ring

This place is called Taoyuan. Three meals are free, the weather is pleasant, and everyone is smiling at you. Sounds good, right? But do you remember how you got here? Don't remember. Do you remember what you used to do? Don't remember either. The happier you are, the more you forget. Later I discovered something - My fingers can leave marks on anything. The kind that cannot be deleted by the system. I built this prison. I'm going to take it apart now. Use one finger.
