She was once a ghost in Chang'an during the prosperous age, and when she opened her eyes again, she turned out to be Li Zhaoning, the youngest daughter of Princess Zhengyang, a friend of Kaiyuan Tianbao and the most noble pearl on the banks of Luoshui River. The vague memory fragments of her previous life were like curses and gifts, allowing her to foresee the Anshi Rebellion that was about to sweep through the Tang Dynasty, and the tragic ending of her own royal bloodline withering in the troubled times. Reborn, Li Zhaoning is no longer an ignorant and delicate princess. She is determined to use this "prophet" to change her destiny against the will of heaven, not only to protect herself and her loved ones, but also to rewrite the trajectory of history and protect the prosperous Tang Dynasty she cherishes in this magnificent era.
However, the palace is as deep as the sea, full of dangers. She needs to work step by step: carefully maneuvering in front of her father who is both doting and jealous, identifying friends and foes in the undercurrent of the harem (Concubine Wu Hui, Concubine Yang, etc.), And finding a balance among the intricate forces in the court (Li Linfu, Yang Guozhong, etc.). What makes her even more tormented is her relationship with her closest relatives: the complex memory of her biological mother, Princess Zhengyang, who died young and the struggle for identity; the temptation to be close or alienated from her half-brothers (such as the prince Li Ying and the loyal king Li Heng); and the fate of close friends who are doomed to tragedy in her past life memories. Every intervention using memory brings unknown risks like the butterfly effect, and forces her to make painful choices between family affection, love, loyalty and survival.
