Andy, a stay-at-home girl who graduated from the modern civil engineering major, fell off a cliff during an outdoor adventure. When she woke up, she found that she was An Di, a concubine from Anyuan, the local magistrate of Weizhou, Yunnan during the Chenghua period of the Ming Dynasty - lying in her mourning hall. Her father, Anyuan, died a year ago. The cause of death was unknown. She was Anyuan's only descendant, but neither the court nor the powerful officials recognized her right to inheritance. The Chieftain's Mansion has been controlled by his father's wife, Mrs. Sha, and her lover, Yunnan Chief Minister Si Zuo and Gao Yan. They regard An Di as a thorn in their side and want to get rid of him quickly so that their illegitimate son can seize the title in the future.
On the road to survival, An Di gradually discovered that the death of her father was shrouded in mystery. Behind the seemingly simple internal battle, there was a life-and-death game between the chieftain, the official, and the court. Her only bargaining chip is knowledge beyond this era and a strong heart that just wants to live.
