Princess Lin Wanjing discovered that she was very similar to the emperor's deceased Bai Yueguang. On the wedding night, she overheard the palace people talking: "After all, he is a substitute, and His Majesty is not even willing to touch it." Desperate, she no longer desired the emperor's love, and instead devoted her energy to accompanying and teaching the young prince. In the process of teaching the prince, she had an intersection with the powerful regent. When Bai Yueguang "resurrected" and the emperor wanted to depose and establish a new one, the heroine, with the support of the regent and the prince's forces, presented evidence of the emperor's mediocrity and supported the prince to ascend the throne. She listened to the government behind the curtain as the empress dowager, completely taking her destiny into her own hands.
