Reborn in the Apocalypse: Rewriting the Fate of the Story’s Cannon Fodder

[Apocalypse Stockpiling + Spatial Storage + Superpowers + Multiple Worlds + No Male Lead] Song Jingwei dislikes her parents' constant restrictions, so on the day of her coming-of-age ceremony, she sneaks out to go bungee jumping. An unexpected accident sends her into the world of a book she read the day before. She's become a cannon-fodder character who dies shortly after making her first appearance. Having read the original story, she knows that the world's “heroine,” her high school classmate, has a lightning-type superpower, while she herself is a cannon-fodder character who supplies the heroine with goods. Song Jingwei decides to stay away from the original heroine and avoid the fate of becoming cannon fodder. Since her part in the book is so brief, she assumes she's just an ordinary person with a few supplies, and that surviving the apocalypse will be incredibly difficult. She'd already planned how to latch onto someone powerful after the apocalypse, but it turns out she's the powerful one herself. Before the apocalypse, she suddenly awakens an ice-type superpower and unexpectedly gains a golden finger, allowing her to live comfortably without worrying about food or drink, even in the apocalypse.
