The Commander's Stepbrother Treats Me Like a Treasure, My Brother Regrets It

Jiang Xinxin, a talented young doctor in her previous life, transmigrates into a novel she read, becoming the cannon fodder supporting female character in a story about a wealthy family. The original plot follows her second brother, Jiang Zhichen, a typical "Dragon Proud Heaven" protagonist who rises to wealth and power, while Jiang Xinxin and her mother, Gu Meifang, suffer and eventually die after the family is reported as capitalists and exiled to the countryside. Upon waking in the body of the eighteen-year-old Jiang Xinxin, she finds herself in a hostile environment where her eldest brother, Jiang Zhigang, has just splashed water on her and entered her room without permission. Instead of cowering as the original character would have, Jiang Xinxin slaps him and refuses to apologize, shocking her family.

The Jiang family consists of her cunning and scheming father, Jiang Bindong, her gentle mother, Gu Meifang, and three stepbrothers from Jiang Bindong’s first marriage. The eldest is violent, the second is the novel’s male lead, and the third is sly. Jiang Xinxin knows the tragic fate awaiting her and her mother: after the family’s property is seized two months later, they are sent to a rural area where Gu Meifang is mocked and commits suicide, while Jiang Xinxin dies in obscurity. Determined to change their fate, Jiang Xinxin reveals through her thoughts that she can be heard by her mother that the family possesses a space bracelet, a family heirloom that will later be stolen by the second brother as a betrothal gift. This bracelet contains a spatial dimension with a villa, farmland, and spiritual water that can grant skills and improve health.

Gu Meifang, who appears to have been reincarnated with memories of her past suffering, realizes the truth of Jiang Bindong’s manipulative courtship and the ingratitude of her stepsons. When Jiang Bindong demands that Jiang Xinxin apologize to her eldest brother, Gu Meifang unexpectedly defends her daughter, declaring that she will no longer tolerate the abuse. The confrontation escalates until Gu Meifang demands a divorce. Jiang Bindong initially refuses, realizing he needs Gu Meifang to perform household chores since he cannot hire help due to political crackdowns on capitalists. However, when Gu Meifang and Jiang Xinxin refuse to work, Jiang Bindong agrees to the divorce to avoid losing his domestic servant arrangement, secretly planning to remarry.

At the Civil Affairs Bureau, Gu Meifang signs away all rights to the family property, taking only her daughter and severing all ties with Jiang Bindong. The three brothers mock them as they leave with nothing. Once divorced, Jiang Xinxin uses a skill gained from fishing in the space bracelet to copy the house key. That night, she and Gu Meifang return to the Jiang residence and systematically empty the house of all valuables, including cash, jewelry, gold bars, and hidden assets stored in properties bought under the sons' names. They store everything in the space bracelet, leaving the house bare.

The next morning, Jiang Bindong and his sons discover the robbery and are devastated, but they dare not call the police due to the sensitive political climate. Jiang Xinxin and Gu Meifang move into Gu Meifang’s parents’ empty apartment, beginning a new life with their accumulated wealth and the benefits of the spatial bracelet. The story sets the stage for the mother and daughter to build a prosperous future while the Jiang family faces the impending political turmoil and their own downfall without the resources they once had.
