Reborn in the Apocalypse, I Have an Invincible Train!

[Reborn a month after the college entrance exam + apocalypse stockpiling + apocalypse train travel + taking down a scumbag and a green-tea bitch] A month after the college entrance exam, a sudden heat wave strikes, followed by the apocalypse. In her previous life, Jiang Rao got into Qingbei University, while her cousin Lin Xiaoru only made it into a vocational college and grew jealous of her. After the apocalypse began, Jiang Rao awakened a metal-type ability and protected her cousin and aunt, bringing them to the Northern Base. Later, while out on a mission, she happened to save the scumbag Wang Hexing. He sweet-talked her into becoming his girlfriend, only for her cousin, jealous of Jiang Rao, to get together with him. The two of them latched onto Jiang Rao and leeched off her! During a massive zombie attack on the Northern Base, the scumbag and her cousin shoved Jiang Rao into a pit full of zombies and watched as she was torn apart and devoured alive. In this life, Jiang Rao is reborn one day after the college entrance exam. She finds the keepsakes her parents left her and accidentally cuts her finger on a rune-engraved dagger among them. Jiang Rao gains a spatial dimension and discovers antiques inside it! She immediately sells the antiques and stocks up on supplies! Using her metal ability, she later builds an incredibly sturdy train. Sitting by its huge picture windows with her loved ones and friends, she watches the zombie hordes outside and takes in the scenery from around the world, setting off on a journey through the apocalypse~
