Doomsday Infinite Exchange System

Xia Mo never imagined that the apocalypse from a novel would descend upon the real world,

nor that one day she'd have to use her limited intelligence to fight a world brimming with malice.

Other people rely on strength, special abilities, and weapons to deal damage. Xia Mo relies on her intelligence to crush them!

But can things really be that simple???

Theme: The world is so big. Can you get by without enough intelligence?
