Tang Xueqing obtained a spatial System a year ago. When the apocalypse arrived, she taught herself hacking, welding, lip-reading, and more. While everyone else fled in terror as the zombies erupted, she went on a zero-cost shopping spree and built herself a safe house.
Ma Siyu, who lost her mother when she was little, obtained a wish-granting System ten days after the zombie outbreak.
Her wish granted her an immune system, so she could never be infected and turned into a zombie!
The well-behaved Jiang Ya obtained a reborn System on the fifth day of the zombie outbreak. She also learned that this world was originally a novel, and the female lead was Ma Siyu!
(The three women each have their own world, but the three worlds have overlapped, and all three are female leads. Each has her own fate.)
