In the 73rd year of the "Collapse Era", humanity's interstellar communication network was completely paralyzed by an unprecedented storm of antimatter radiation. Colonial galaxies have become isolated islands of information, and once-prosperous interstellar civilizations have fallen into silence and panic. In this desperate situation, the special profession "Quantum Ghost Messenger" came into being. These messengers rely on the "quantum resonance devices" they wear to establish connections with the "quantum ghosts" floating in the universe. The so-called "quantum ghosts" are actually fragments of the deceased's consciousness left in the quantum sea. Messengers resonate with them through special devices and encode information in these unstable quantum states for transmission. But this ability comes with huge risks. Every deep contact with the quantum ghost will expose the messenger's memory to the threat of contamination and tampering, just like carefully sailing in an ocean full of whirlpools, and it will be swallowed up if you are not careful.
