The Forbidden City is deep, and the red walls lock the soul. Hai Lan drank in hatred and died, but when she opened her eyes again, she returned to her golden years and when she first entered the palace.
The pain of humiliation, betrayal, and separation of flesh and blood in the previous life is unforgettable. In this life, she vows not to be a plaything in the hands of others and to be trampled on by others.
Under the waning moon in the cold palace, she quietly picked up her edge. The timid eyes of the past are now only as clear as ice and calculating. The suspicion surrounding the mother's premature death, the mysterious relics of Hanbu, the collusion between the traitor "Eagle" and the "nobles" in the palace... Under the heavy fog, there is a blood feud that is deeper than personal grudges.
Joining hands with a forbearing ally (Chen Wanyin), and getting acquainted with a talented woman (Yi Huan) who carries the same secret, Hailan weaves her own web of murderous moves. Her favorite concubine Gao Xiyue's difficulties and Jin Yuyan's hidden smile were all discarded pieces on her chessboard. Even Ruyi, who once regarded her as a biological sister but turned a cold eye in the end, became a stumbling block in her path to power.
The biggest variable is her son Yongqi, who was born weak due to conspiracy, but is as smart as a demon. She sacrificed her son to plan the plot and used herself as a bait. She combined her mother's despair with the coldness of a counselor, just to fight for a future of nirvana and rebirth for her mother and son in this man-eating abyss.
From a humble official girl to the powerful harem concubine Lan Guifei, from being at the mercy of others to playing chess in the world. Every step Hailan takes, he steps on the bones of his enemies and the blood and tears of the past. When she finally stands on the top of the Forbidden City, overlooking thousands of miles of mountains and rivers, can she uncover all the mysteries and complete this revenge and redemption that spans two lives?
