This is not a carefully scripted scenario; it is a fully operational anomaly universe. From the logic layer up, the system generates complete forbidden realms containing rules, anomalies, scenes, NPCs, and causality. Here, rules are both protection and traps. You are not a god; you are merely a participant struggling to survive in this world. You must observe, deduce, and trial-and-error your way through cognitive pollution and logical paradoxes to find even a sliver of hope. Remember: do not easily trust the rules you see, for the rules themselves are the anomaly.
