Jiang Wanyue, the legitimate daughter of the Duke of Zhenguo, made a mistake in her previous life. She was framed by her husband, the third prince Xiao Heng, and her concubine Jiang Wanyun. Her family was ruined and she died tragically in the cold palace. On the eve of the spring banquet when she was reborn as fifteen years old, she returned with hatred, vowing to protect her family and pay for her blood debt. In this life, she suppressed her innocence and worked step by step - outsmarting the house fight conspiracy, making an alliance with the eldest princess, secretly establishing a business intelligence network, and using her medical skills and wisdom to get involved in the disputes in the court. When she found out the cause of her mother's death and overthrew her enemies, she discovered that her life experience was implicated in the secrets of her previous dynasty. Let's take a look at how Jiang Wanyue grew from a girl in a boudoir to a legendary woman playing chess in the world, and finally rose to the top of the sky and created a vast world of her own.
