No heroine + wasteland + fourth natural disaster
In the 200th year after the annihilation of the world, the ashes of this old world are waiting to be restarted. The survivors in the wasteland here survive between the radiation dust and mutant species, and the scavengers survive by picking up garbage.
Until one day a group of creatures calling themselves "players" appeared out of thin air.
They are still shouting "strategies", "dungeons" and "health bars" that no one can understand, and they are always chattering to the air - they are all exhausted. The key is that they will see the same figure appear in front of them in the near future.
The residents of the wasteland, who gradually realized something was wrong, panicked.
The old mayor tremblingly added in the book: "The fourth natural disaster is immortal, bloodthirsty (?), Likes to collect scraps, and is the enemy of all living things (or maybe just playing)."
