Gu Yan, a top student in the Department of Modern History, accidentally traveled to the fictional dynasty "Zhaoning" due to a broken page from an ancient book, and became the legitimate daughter of the Gu family in Yunjing. The original owner fell to her death because she was involved in family secrets. She was forced to leave the house despite being accused of "restraining relatives". During her escape, she was as cold as ice and unexpectedly tied up with Xie Zhao, a businessman who was cynical on the surface but actually transparent. The two went from hating each other to working together to solve the mystery of the "Gu family's blood curse". The original owner's cousin Zhou Chengli was overshadowed by Gu Yan since he was a child, and was marginalized due to family interests. He gradually turned from a gentle boy into a dark person. He set up a scheme to involve the two in the whirlpool of dynasty change, and eventually went to destruction in the intertwining of love and hate. The story unfolds from a first-person perspective, connecting personal destiny and the world's chess game through clues from the broken pages of ancient books. There is no golden finger, and the game relies entirely on wits and human nature.
