Arbiter of the Uncanny

In this world, ghosts are no longer a collection of idealistic resentments, but "wrong physical parameters." ●Core axiom: Ghosts are "BUGs" in real-world code. Their existence violates the laws of thermodynamics, the principles of optics, or common sense of electromagnetism. ●Unkillability: You cannot kill a "bug". You can only mask it by fixing the parameters (using rules), or overwrite it with another bigger "bug" (stronger ghost). ●Confrontation logic: ●Ghostland = physical quarantine area. The realm that ghosts expand actually modifies the physical constants of local space (such as gravity reversal and light speed reduction). ●The law of killing = triggering mechanism. For example, "You will die when you hear a sound". The essence is that the vibration frequency of sound waves triggers the ghost's resonance killing program.
