I Transmigrated Into a Villainess Supporting Character and Got Bound to the Gloomy Antagonist Before His Downfall

Jiang Sui transmigrates into a female-centric apocalypse novel, landing in the body of a vicious supporting character who is the fiancée of the story’s final villain, Xie Yanhan. The narrative begins at a critical late stage where Xie Yanhan, having escaped a brutal research facility, has risen to power as a terrifying mass murderer. Jiang Sui finds herself imprisoned alongside other suspects in his blood-soaked hall, facing imminent torture and death. Just as execution is imminent, a system activates, recalibrating her timeline and returning her to the beginning of the original story. The system offers a resurrection card in her original world if she completes the role of the malicious fiancée and advances the plot. Jiang Sui refuses, choosing to survive on her own terms rather than endure the psychological torment of abusing Xie Yanhan, who is currently a broken, abused live-in fiancé in the Jiang household.

With the system’s guidance removed, Jiang Sui faces the immediate challenge of the impending apocalypse. She discovers she has almost no money, having inherited the original host’s debts and poverty. Determined to survive, she executes a plan to liquidate her assets. She sells her inheritance rights and the family villa to her stepmother, Luo Dongxiang, securing five million yuan. She also extracts additional funds from her half-sister, Jiang Lingling, through intimidation, and from her father under the guise of needing money for a social event. With capital in hand, she liquidates her remaining luxury goods and takes out loans where possible, amassing a modest but crucial sum for survival.

Jiang Sui’s primary goal is to reach Chong City, a location with a milder climate suitable for surviving the extreme cold wave predicted to follow the apocalypse. She rents an apartment for Xie Yanhan, providing him with supplies and a place to stay, effectively removing him from the abusive Jiang household. This act of kindness confuses and disturbs Xie Yanhan, who is accustomed to cruelty and exploitation. He watches her离去 with a cold, calculating gaze, noting the strange shift in her behavior. Jiang Sui then drives to her grandmother’s abandoned orchard in the mountains, where she had previously identified a sturdy house with underground storage. She hires a cleaning crew and contractors to fortify the property, installing anti-theft windows, reinforcing doors, and converting a warehouse into a greenhouse. She stockpiles vast quantities of food, water, medicine, and weapons, including a compound bow and handmade spiked clubs.

As she prepares, signs of the coming disaster emerge. Mutated fish and berserk wild animals appear in online videos, and Jiang Sui witnesses a horrific chain-reaction accident caused by a mutated creature on the highway. Despite the growing chaos, she attends a family banquet to reconnect with her half-sister, Jiang Shuangxue, the novel’s female protagonist. Jiang Sui apologizes for past wrongs and warns Shuangxue about the impending disaster, hoping to build a alliance for the future. During the banquet, she encounters Shen Hanyu, Xie Yanhan’s counterpart or related figure in this timeline, who displays a similarly cold and dangerous demeanor. After the banquet, as Jiang Sui drives Shen Hanyu to Central Park, the apocalypse erupts. The city is engulfed by the Aurora Mushroom, an S-class contamination source that releases spores turning humans into fungal vessels. Chaos ensues as people mutate and attack one another. Jiang Sui’s car is struck in the ensuing panic, and she loses consciousness, waking up to a world already transformed by the pollution outbreak.
