Xie Mingzheng was an orphan who was sold three times in fifteen years. She struggled to survive through bullying and beatings.
Not long after the news came out that the fake daughter of the Zhenguo Palace had eloped with the scholar, the real daughter in the brothel was killed by the mistress. At that moment, she decided to replace the real daughter.
She wanted to use her status as a real daughter to enter the Zhenguo Duke's mansion and become the concubine of the Zhenguo Duke's palace.
Unexpectedly, the Zhenguo Palace was like a wolf's den.
Her father is useless, her mistress wants to kill her, her third aunt is trying every possible means to drive her away, and her younger brothers and sisters are eyeing her.
She also carried a marriage contract on her body. Once the prince became seriously ill and the marriage contract was brought forward, she was carried into the East Palace to celebrate the wedding.
Everyone wants her to be a chess piece, but they don't know that she has poison in her sleeves and a knife in her heart.
While resisting her fate, she also discovered the truth about her life experience...
When the truth emerged, she fought and grabbed everything that belonged to her and didn't belong to her. She wanted it all.
