World view setting
Time node: In the late autumn of 2065, three years after the quantum computer broke through the singularity, it was a critical moment for the global energy network to complete its upgrade.
Spatial structure: The surface of the earth is covered with void dust with quantum entanglement properties. The underground bunker uses graphene-liquid metal composite armor, which can temporarily isolate dust penetration.
Catastrophic characteristics: The final echo is essentially a dimensional interference wave released by alien civilization, which causes the collapse of the earth's material foundation through the quantum entanglement effect.
Purpose: Survival in the apocalypse, restarting civilization, the game between human nature and technology
