How can a modern soul change its destiny when it travels back to the prince Li Chengqian who is destined to be deposed? The battles in the court are shocking at every step. In the dream, I repeatedly saw a vague figure in the background of the Xuanwu Gate Incident, handing the young Li Chengqian a strange (not made in the Tang Dynasty) jade pendant, and whispering a broken prophecy: "The dragon falls to inherit Qian, the phoenix cries...". Who is this figure? What is the meaning of the prophecy? This jade pendant disappeared later. What secret did it hide? Is it related to Li Chengqian's rebellion in history?
