Aya Wei, a modern history student, accidentally traveled through time and became a female official in the Queen's Palace. She used modern knowledge to crack down on the poisoning conspiracy, and helped the queen consolidate her position with the idea of "turning the workplace into a palace fight": she improved the account books to find out the insider, and used sacrificial rituals to counterattack the trap. In the process, she and the seemingly idle Seventh Prince Xie Heng became acquainted with each other through intelligence transactions, and they went from testing each other to secretly falling in love. Xie Heng helped her obtain the latest news from the previous dynasty, while Lingwei conveyed the secrets of the harem to her. The two protected each other in the turbulent power struggle, and finally helped the queen gain a firm foothold and gain sweet love.
