Mu Lingyin, the direct daughter of the Imperial Tutor, has been hiding behind the scenes for many years, assisting her husband Yan Zhaoran with her extraordinary resourcefulness and hard work, paving the way and building bridges for him, helping him stand out in the turbulent court, and finally firmly sit on the throne of the crown prince. She originally thought that years of hard work would eventually lead to a mutually beneficial future, but reality gave her the cruelest blow. On the night when she was canonized as the crown princess, the red candles were swaying, and the joy had not stopped, but Yan Zhaoran appeared in front of her with her concubine Mu Ranshuang, who had come as her dowry. Before Mu Lingyin could react, the knives in their hands had pierced her body at the same time. In severe pain, she saw clearly the undisguised indifference and calculation in their eyes - it turned out that the man and woman had already been in secret, and her existence was just a stepping stone on their way to seizing power. Mu Lingyin secretly made up her mind to take revenge on the prince Yan Zhaoran and concubine Mu Ranshuang who had destroyed her entire family by clinging to Emperor Yan Ciyuan and sitting on the throne of the Supreme Phoenix!
