In her previous life, Su Li was a spirit fox who had only just taken human form. She had planned to head down the mountain and see what the outside world was like, but on the way, she witnessed a murder with her own eyes. The victim was the current Empress, Wei Muyi. When Su Li tried to save her, she realized it was already too late. Before dying, Wei Muyi spoke of her final wish: "I have done many things wrong in my life. Now, the only thing I cannot stop worrying about is my son. Miss, please help me. Enter the palace and keep my son safe. His name is Yan Cheng, and he is about sixteen."
So Su Li agreed. With her exquisite looks, she entered the palace with ease, rising from palace maid to Empress. Along the way, she was decisive and ruthless, and ultimately earned the reputation of a demon empress. Her beauty was enough to captivate the emperor and make him neglect state affairs. When everyone wanted to kill her, she demanded that the crown prince's position be given to Yan Cheng, promising to take her own life in return.
But when the succession was to be announced, a rebellion broke out in the palace. The rebels killed Yan Cheng. Su Li saw the man leading them, surrounded by an aura of blackness. He was undoubtedly a demon. She revealed her true form and fought him, but died in the battle. After Su Li's death, Jing Zhan ascended the throne and unified the realm, slaughtering innocent civilians until the human world became a place of bloodshed and strife.
Unable to bear it, Su Li sought out Lin Wan, the author of the story, and asked her to transmigrate into a book and change the plot she had written. So Lin Wan transmigrated into the book as Su Li, approached Jing Zhan, and gradually won him over.
