Shen Ling transmigrates into a puppet emperor who rules disguised as a man and unexpectedly becomes bound to the Foolish Emperor System. To stay alive, she racks her brains to play an incompetent tyrant. Her outrageous antics throw the royal court into chaos—and stir the heart of Gu Yan, the all-powerful Lord of Nine Thousand Years.
Shen Ling’s sudden moments of intimacy gradually wear down Gu Yan’s resistance, until familiarity turns into fierce possessiveness. But when both their hidden identities are exposed, Gu Yan believes everything was part of Shen Ling’s scheme. Enraged at having been manipulated, he returns to neighboring Wu State, reclaims his identity as a prince, seizes the throne, and marches against Huai State.
As they spend more time together, their misunderstandings finally unravel. They unite the realm and become lifelong partners.
