This is a story that the author himself doesn't know how to describe.
Wan Cixia, a girl who is severely addicted to the Internet, ended up on the streets one day because she stayed up late to play games. She was bound to an incomprehensible system and traveled through time.

Wan Cixia: Sister~(￣▽￣~)~! I can!
Mission: Optimistic life, positive attitude
