In the thirteenth year of Dajing Zhanghe, Lin Wanning, the daughter of a businessman, came to Beijing with the former emperor's contract in hand. She was about to make an appointment with the princess. However, she encountered the prince Shen Shubai who was clinging to the general Su family and had a close relationship with Su Muqing. She even heard that he regarded the contract as a waste of paper and secretly raised the estranged wife Wan Niang, who was eight months pregnant. Queen Wen Shuhua and the emperor's sister-in-law Wen Jinyu, who is the emperor's "Bai Yueguang", are planning how to put the outer chamber in power. Twelve-year-old Lin Wanning was as cold-hearted as iron. Every man in Dajing treated women as pawns to seize power. But she is not alone - her domineering elder brother is in charge of the family business, her cold second brother is highly skilled in medicine, her twin brother shares the same hatred with her, and she is accompanied by Xu Jinglan, an orphan of a general who is highly skilled in martial arts. The Lin family's money was never given in vain. Since the prince had betrayed his trust, she took off the fig leaf of the East Palace and let this group of greedy men know that women may not be inferior to men in skill.
