A tragedy that wiped out a family, a bloody feud.
Yin Zhengyuan, the minister of household affairs, was falsely accused of collaborating with the enemy and his entire family was executed. The only daughter Yin Zhijin escaped by chance, changed her name to Yin Yunqing, and entered the palace as a palace maid. She vowed to make her enemies, the queen's father Jiang Boyong and her brother Jiang Huaiyuan, pay with their blood.
The first step in revenge is to attract the attention of the current emperor Ling Yu.
Ling Yu—he ascended the throne at a young age, was cold and unhappy, and had three thousand beauties in the harem, but no one could warm his heart. He lives in endless calculations, and even the queen of his pillow is an opponent he has to guard against. Until the palace maid who seemed weak but was actually strong appeared, his heart, which had been cold for many years, felt warm for the first time.
However, Yin Yunqing approached him initially just for revenge.
In the harem, Queen Jiang Liuxuan is sinister and ruthless, Concubine An Suying's life experience is a mystery, Concubine De is domineering, Concubine Shu is secretive... All forces are intertwined, and every step is like dancing on the tip of a knife.
The deep palace is like the sea, and the red walls are like cages.
When revengeful love intertwines with sincerity, and when the truth about the substitute gradually emerges, can she survive to the end within this man-eating palace wall? Can he learn to trust and love?
And what role will the seventh prince Ling Feng and the important minister Jiang Wei, who secretly protect her, play in this chess game?
The sky inside the palace walls is never clear.
This is a story about revenge, love, intrigue and redemption.
