Quick Transmigration: Stuck with a Bugged System

Qu Ping, an utterly ordinary young woman, accidentally gets bound to a special mission System. Along the way, she goes from silently putting up with everything to fearlessly calling out the big shots, while leveling up a System that had spent centuries stuck at the bottom. The two become close friends through their missions, and in the end, the System is willing to give up everything to change the course of Qu Ping's mother's life. Later, the System discovers that its Host has been hiding her true abilities all along! At least it bound itself to a big shot in time. After fulfilling her wish, Qu Ping makes a comeback with the lowest-spec System in the Milky Way!
