Su Wantang, a modern elite, transmigrated into a historical conspiracy novel and became the concubine of the same name - a cannon fodder who was pushed out to marry as a substitute for family interests and was destined to be buried soon after the marriage due to strife in the back house and her husband's death due to illness. Faced with a certain death gambit, Su Wantang, who knew the plot of the original novel, accepted the marriage docilely on the surface, but on the inside, she was plotting how to use the information gap to break the situation. The one she wants to marry is Xiao Yan, the male protagonist who was weak due to poisoning in the early stage of the original work, but later rose to power and became the leader of the world. But at this moment, he is still a "waste" who was abandoned by his family and is dying. Relying on modern management knowledge and a precise grasp of people's hearts, Su Wantang worked step by step in the complex back house of the Xiao family to save the lives of herself and her "sick man" husband; while secretly operating, accumulating resources, and quietly changing the trajectory of the original work. She originally wanted to wait for Xiao Yan to "pass away" and fly away with her wealth, but she found that this husband not only gradually recovered, but also looked at her with an increasingly dangerous and profound look. When she tried to "escape" according to the original plan, the young master who was supposed to be unruly and unwavering in his love for the original heroine held her tightly in his arms and whispered: "Madam disturbed a pool of spring water and just want to run away?" Su Wantang was shocked to realize that she seemed to have accidentally completely distorted the "love saint" character of the original male protagonist.
