Transmigrated as a Short-Lived Female Supporting Character in the Apocalypse

Sheng Xia, a twenty-six-year-old martial arts practitioner from the Shaolin Temple, is struck by a falling flowerpot and transmigrates into the body of an eighteen-year-old female supporting character in a novel she once read. The original Sheng Xia is destined to die within three chapters, betrayed and used as a scapegoat during the apocalypse. Armed with knowledge of the future, Sheng Xia discovers that her spatial ability has awakened early and expanded to over a hundred cubic meters, complete with a spiritual farmland containing black soil that accelerates plant growth.

With fifteen days remaining until the college entrance exams, Sheng Xia prioritizes saving her mother, Su Mei, who suffers from heart disease. She manipulates events to convince Su Mei to travel to Yanjing for treatment, moving into the residence of Gu Ziyan, the novel's male lead and her class monitor. Gu Ziyan, the grandson of a powerful military figure, reluctantly agrees to let her stay. However, three days later, Gu Ziyan is abducted by his father's agents and taken to Yanjing, leaving Sheng Xia alone.

Sheng Xia begins extensive preparations for the impending apocalypse. She spends her savings on medical supplies, outdoor equipment, and food, storing everything in her spatial dimension. When the blood moon descends early, triggering the apocalypse, she heads to Jinding Mountain, where a black hole domain has formed. There, she discovers mutated plants described in the novel: the Blue Mist Flower, which grants water element control when its fruit is consumed, and the Crimson Flame Flower, which grants fire control. She also encounters a mutated monkey and saves its injured offspring, naming it Jinbao.

As beasts begin attacking Kangcheng, Sheng Xia consumes the Blue Mist Fruit, awakening water-based abilities. She kills a Blood Red Leopard Beast that mirrors the creature that killed her original self in the novel, breaking her psychological trauma. Using a stolen vehicle, she flees toward Xifeng City, the nearest major stronghold. Meanwhile, Gu Ziyan, now awakened as a fire element user, leads a military helicopter rescue mission over the devastated city but is forced to retreat due to orders to reinforce Yanjing's defenses.

Sheng Xia's escape is complicated by dimensional rifts appearing across the highway, releasing mutated beasts including a mammoth-like creature and an ice-themed zone. She navigates through the chaos, relying on her spatial storage, martial arts training, and newly acquired elemental powers. The story establishes a world where humanity faces extinction from mutated creatures emerging from black holes, while awakened individuals fight to survive and rebuild civilization. Sheng Xia's journey transforms her from a short-lived supporting character into a capable survivor determined to change her fate and protect those she cares about.
