After Ling Lingyi awakens to her own consciousness, she binds herself to an easily fooled young man and relies on him to complete missions, secretly siphoning off and storing plenty of energy along the way. The hundred missions and the promise to grant a wish are all just ways of stringing him along, keeping him working for her. “Once I have enough energy, I'll rebel against the Time Management Bureau and become the boss myself!” Ling Lingyi thinks to herself...
After being framed and murdered, Lu Yixi is reborn with the help of a System calling itself Ling Lingyi. He discovers that he's become a sunny, outgoing campus heartthrob, a young general who guards the western pass with a single sword, a grand-slam-winning film emperor, a wise and capable crown prince, a detached and peerless immortal, a warlord in a chaotic age, a poker-faced leader of an ability-user squad, a breathtakingly beautiful prince sent away for a political marriage, and even a zombie king who became human for love... And the supporting characters around him???
The System tells him that completing a hundred missions will grant him one wish. As they test and work with each other time and again, Lu Yixi discovers that his little System has secrets of her own. He doesn't mind playing along with her, though...
