Bai Yu unexpectedly transmigrates into an apocalyptic supernatural ability novel, becoming a silver-haired, low-level zombie with virtually zero combat power and binding himself to a portable supermarket survival system. At the very beginning, he encounters Lin Qingyuan, the "Zombie Nemesis," who is seriously injured. Driven by an overwhelming desire to survive, he locks her in an iron cage, only to trigger a system quest to increase her favorability. He grits his teeth and feeds the female protagonist, ventures into zombie nests to gather medicinal herbs, and completes all kinds of absurd missions, gradually turning the situation around from a favorability score of minus one hundred. Facing repeated schemes by the original male protagonist, Su Rui, and Ruan Ying, Bai Yu relies on his foreknowledge of the plot and the system's support to overcome each crisis. He also wins over the cold and proud, phoenix-like female protagonist with his sincerity, and in the cruel apocalypse, they become each other's one and only source of support.
