Li Jingxun, a beautiful doctor from the Department of History and Archeology of Western University, accidentally traveled to the Daye reign of Emperor Yang of the Sui Dynasty while excavation of an ancient tomb in the middle period of the Sui Dynasty, and his soul passed through the body of Li Jingxun, an orphaned princess of the same name and the same name in the Northern Zhou Dynasty. At this time, the world was in chaos, and undercurrents were surging everywhere. She originally wanted to hide from the world and protect herself, but due to a palace incident, she was involved in a dispute over imperial power. The original owner's memory is incomplete, and he only knows that he is responsible for a blood feud, and the truth has long been buried by the years. King Yang Zhao of Jin Dynasty was framed by his brothers, defeated and demoted, and lived in the south of the Yangtze River. He was obsessed with it and vowed to return to the pinnacle of power. The fate of the two people is intertwined. One has modern wisdom and calm insight, and the other has secret information and old forces, working together to deal with the court and the harem. The prince is cruel and easy to kill, the princess is cunning and scheming, the vassal king has a lot of troops and ambitions, and all the forces are fighting for control. As an orphan of the Northern Zhou Dynasty, Li Jingxun circulated among the nobles of the Sui Dynasty, relying on his golden finger - his mastery of ancient rituals, government maps, and success every step of the way. Rebirth is not a miracle, but a price; revenge is not only blood debt repayment, but also a chess game that subverts a dynasty. Chaos is about to break out in the world. Who will be the chess player and who will be the victim?
