Shen Shuli, the concubine of Dingbei Hou Mansion, was made into a rough servant girl by her aunt Wang after her biological mother died young. She secretly took note of the omissions in the government's accounts and the handles of each house, and took advantage of her sister Xiao Yurong's marriage to the Prince's Mansion to use the excuse of "substitute marriage" to rebel against the Wang family and regain control of the inner courtyard. From investigating the shortage of the treasury to resolving the external pressure, from dealing with the prince's marriage situation to solving the truth about the death of the late wife, she worked step by step. Not only did she keep the Hou Mansion at the forefront of the change of imperial power, she also revealed the family secrets of the murder of her biological mother in the game with Xiao Chengyu, the Marquis of Dingbei. In the end, as the "Mother of the House", she punished those who bullied her one by one, and became the core of the Hou Mansion's authority that attracted the attention of the Sixth Palace.
