After the "Red Mist Catastrophe" in 3073, the earth was reduced to a wasteland: 70% of the land was occupied by mutated creatures, and the remaining humans gathered in "fortress city-states" with extremely scarce resources. At the same time, there was a mysterious "rule domain", and those who violated the rules would be obliterated by unknown forces.
Lin Che, who died suddenly after staying up late to live broadcast, traveled through time and was reborn in a dilapidated apartment in the city-state "Rust Iron Town" on the edge of the wasteland. She was bound to the [Ultimate Level Apocalyptic Live Broadcasting System], and the world of the apocalypse has changed since then.
