When Jiang Lingyi woke up, she became the legitimate daughter of the Hou family whose identity was secretly changed by her concubine Jiang Wanning and her engagement was taken away. She returned to Beijing in hibernation, vowing to seek her innocence, but found out that this replacement was implicated in old royal cases and court conspiracies. She and the regent He Lanheng went from testing each other to breaking the situation side by side, and gradually regained their destiny amidst Rong Chang's suspicion, Empress Dowager Fu's calculations, and the evidence held by Liu Cheng'en. When the palace gate was drained of blood and Jiang Wanning became a slave, Jiang Lingyi finally ascended to the position of Queen Mother.
