After struggling through a decade of apocalypse, Li Chenxi, a ruthless survivor, was betrayed by her base during a zombie siege. When she opened her eyes, she found herself back in the world just half a month before the apocalypse began! At that time, her scoundrel father, stepmother, and wicked stepmother were still pressuring her to vacate her room for her brother's wedding. This time, Li Chenxi decisively sold the house to them at an extremely low price. While they smugly thought they had struck a great deal, Li Chenxi used the money to frantically stockpile supplies! With the assistance of the super base system's powerful advantages, Li Chenxi's invincible shelter was swiftly constructed. While everyone else was caught in the throes of the zombie crisis, Li Chenxi was leisurely vacationing in her shelter. As others starved, Li Chenxi's dog enjoyed a daily buffet! While others struggled and crowded into survivor gathering spots in fear and distress, Li Chenxi's base had already become the world's most impregnable fortress of steel and iron!
