To keep the world from falling apart, she accepts the System’s mission: raise the young emperor Xie Lang and help him become a wise ruler. So Wen Hemian kicks out corrupt officials and reforms the law, helping the young emperor secure his throne while earning the hatred of a host of people. At last, as the capital’s political turmoil grows and Wen Hemian realizes her secret identity is on the verge of being exposed, while the little emperor’s gaze grows increasingly strange, she turns and leaps off a cliff without hesitation, faking her death and making a clean escape. She doesn’t notice that after she falls, the young emperor rushes to the scene, his eyes red with murderous rage. - When Xie Lang was young, there was someone he could never have. That person was the tutor chosen for him by the late emperor, a brilliant young scholar who passed the imperial exams at sixteen and dazzled the world. Wen Hemian taught him and showed him how to become a noble, enlightened ruler. But just after he secured his throne, she fell off a cliff, her fate unknown. So Xie Lang went mad, and everyone knew it. - After three years of peaceful living, Wen Hemian is informed that the child she raised has turned evil. She has no choice but to return to the capital and clean up the mess. But not long after entering the city, she turns around and comes face-to-face with the wolf cub she raised. The young emperor’s eyes are bloodshot and his gaze sinister as he gives her a chilling smile. “Tutor, you’ve finally decided to come back.” “Would you have to become a tyrant to make sure I never leave you?”
