In her past life, Lin Qingning searched for supplies for her fiancé Xu Lang in the acid rain apocalypse, breaking her legs and getting disfigured, only to watch him take her best friend Zhao Ruoyun onto a life raft and kick her into the flood. Reborn one month before the apocalypse, she sold her house, hoarded grain and medicine, reinforced the top floor, and took back the mysterious jade bracelet with infinite storage space. In this life, while others fight for instant noodles, she eats hot pot; when scumbags smash her door, she watches the drama on surveillance; when the acid rain, extreme cold, and raiders strike, she lives more and more comfortably. The only out-of-control variable is the mysterious man Xu Yi from next door, room 3202, who built his shelter just like her and stood by her side time and time again. The apocalypse turns people into beasts, but it also made her see clearly that what is truly worth protecting has never been just food.
