In her previous life, Lin Zhixia was a max-level host of the battle system. Before the final showdown, she was ambushed and killed by Su Wanqing, the reborn campus beauty, and her boyfriend, Gu Mingchuan. She returns to the day the systems arrive, but the strongest system is snatched away, leaving her with only a wish-granting system that cannot kill living beings. She traces the source of the apocalypse and rescues Chen Mo, who was sealed inside a coffin and is about to become the progenitor of zombies. She unleashes her family's biological resources to eradicate the virus, exposes the truth that the battle system feeds on disasters, and ultimately wishes for all systems to be permanently shut down—so the world will never face another apocalypse and will never need a savior again.
