The end of the world is upon us, and Xu Chichih, a young girl with a heart condition, is brutally dumped by her parents in a dead city.
Countless fae and monsters are born from this dead city, and human beings spend all their efforts to resist the invasion of fae, and the city is blocked off, completely becoming a "forbidden zone for the living".
No one knows that in this city, which can be called a monster's lair, a young girl is quietly sitting in a wheelchair playing a game console that suddenly appeared.
Every time she successfully raises another powerful family member in the game, the black fog enveloping the entire city will also surge, and one by one, the fae monsters that bowed down to the girl in the game and called her "mother" will continuously emerge from the fog and rule the entire city.
When the outside world is finally ready to explore this city full of death and crisis, unbeknownst to them, there is already a skinny girl who has become the god of all the monsters in the forbidden zone!
