Transmigration: I'm the Wicked Supporting Female Character!

Yu Zhaozhao, a highly skilled 21st-century special agent, finds herself transmigrated into the body of a vicious supporting female character in a historical romance novel set in 1970s China. The original owner, also named Yu Zhaozhao, was an orphan raised by her greedy uncle, Yu Wangshan, and aunt, Mao Cuizhi, after her military officer parents died in the line of duty. The uncle and aunt stole her parents' compensation money and job placement, forcing the girl into servitude. In the novel's plot, the original Yu Zhaozhao was sent to the countryside in place of her cousin, Yu Miaomiao, where she was bullied and eventually drove herself to madness after unrequited love for the male lead, Zhao Nianze. Now inhabiting this body, Yu Zhaozhao discovers she has inherited a massive secret fortune, including a passbook with 16,800 yuan, a valuable jade pendant, and a deed to a luxurious villa in Beijing with a hidden basement of gold and antiques. Most importantly, the jade pendant grants her access to a spatial dimension containing her modern villa, fully stocked with food, supplies, and advanced technology, including a surveillance system linked to a television.

Upon realizing her dire situation, Yu Zhaozhao immediately begins to formulate a plan for survival and revenge. She learns that her name has already been submitted for sent-down youth labor in the countryside, a fate she intends to alter while still ensuring her abusive relatives face consequences. She retrieves her hidden passbook and heirlooms from a storeroom, where the original owner had concealed them in a pair of dirty cotton shoes. Using her agent skills, she disguises herself as a middle-aged man to withdraw the bulk of her money from the bank, and then as a glamorous woman to withdraw the remaining funds from her aunt's account. She also successfully registers her cousin Yu Miaomiao and brother Yu Tianbao for countryside labor, securing subsidies for herself while condemning her bullies to the harsh northwest. She visits the black market to purchase essential supplies, including meat, eggs, and ration coupons, demonstrating her resourcefulness and preparedness.

Yu Zhaozhao's revenge against her uncle is swift and calculated. She follows Yu Wangshan to his secret mistress's home, where she overhears his plan to fake a divorce to seize property. She digs up a buried box of gold bars and stolen factory resources, storing them in her spatial dimension as evidence and loot. She then mails an anonymous report letter to the authorities, detailing Yu Wangshan's corruption and affair. The next morning, the neighborhood committee and red armbands raid the mistress's home, arresting Yu Wangshan and seizing the stolen goods. Simultaneously, officials arrive at the Yu household to inform Mao Cuizhi and Yu Miaomiao that they, too, are being sent to the countryside, stripping them of the job and status they had stolen from Yu Zhaozhao. The family is left in chaos, having lost their money, their home, and their freedom.

With her family's downfall complete, Yu Zhaozhao boards the train to the countryside, leaving her past behind. On the train, she encounters Jiang Jizhou, a handsome and disciplined military officer leading a special operations team. She witnesses a hostage situation involving suspected spies and, despite her initial reluctance, agrees to help the authorities by disguising herself as a train attendant to infiltrate the suspects' compartment. In exchange, she negotiates for a sleeper berth, securing a more comfortable journey. Her actions on the train mark the beginning of her new life, where she must navigate the complexities of the era while maintaining her secret spatial advantage and avoiding the tragic fate that befell the original character.

As the train travels north, Yu Zhaozhao reflects on the stark contrast between her previous life of luxury and the hardships awaiting her in the rural setting. She is aware that the college entrance exam will not be restored for two years, meaning she must endure the countryside labor for some time. However, with her spatial dimension providing an endless supply of modern food and necessities, she is well-equipped to survive. Her primary goal shifts from mere survival to building a new life on her own terms, leveraging her future knowledge and hidden assets. The encounter with Jiang Jizhou introduces a potential ally or romantic interest, complicating her plans for a solitary existence. She resolves to stay away from the novel's original female lead, Jiang Yan, whose presence brings trouble, and instead focuses on securing her own independence and happiness.

The story sets the stage for Yu Zhaozhao's transformation from a victim of circumstance to a powerful figure who controls her own destiny. Her agent training, combined with her spatial cheat, gives her a significant edge over her peers. As she approaches her destination, she is ready to face the challenges of rural life with confidence and cunning. The downfall of the Yu family serves as a testament to her strategic mind and willingness to act decisively. Her journey is no longer about escaping a bad ending but about creating a new narrative where she is the protagonist, not a pawn in someone else's story. The arrival at the countryside marks the beginning of a new chapter, filled with potential for growth, adventure, and the pursuit of a life she truly desires.
