Shen Zhiwei worked as the mistress of the Yongning Hou Mansion for fifteen years, providing comfort to her mother-in-law, caring for her children, and managing the general affairs of the Hou Mansion. She made the precarious Hou Mansion as stable as Mount Tai. Now that her children have grown up and the foundation of the Hou family is solid, she just hopes to be relieved of her burden and die peacefully, with a happy ending. But who would have expected that the concubine secretly harbored dissatisfaction with her, and her concubine and her son came to her door. Even the Marquis, who had already respected her like ice, suddenly treated her differently. Shen Zhiwei sneered, trying to ruin her plan to die? Then don't blame her, the mistress, for taking charge of the Marquis Mansion again and liquidating the demons and monsters one by one!
