Back to the Apocalypse: Turning the Tables with a Life Simulator

[Apocalypse + Rebirth + Golden Finger + No Romance + Infrastructure Building + Shopkeeping] Welcome to Mary Sue's Shop~ Shen Baozhu had no car, no house, and no savings. She struggled to survive in the apocalypse for five years, only to starve to death. Even her death was so pathetic. When she opened her eyes, she was back one month before the apocalypse. Remembering how she'd eaten tree bark in her past life, she was glad that her life simulation started at just the right time. [One year into the apocalypse, after living on instant noodles and snacks every day, you've become a plump little thing. Rather than spend your life gnawing on tree bark again, you hang yourself. The end.] [Acquired the sensation of hanging yourself] Death after death, Shen Baozhu was still holding on, but the System ran off first. Shen Baozhu: You can't leave me all alone~ Life Simulation System: I'll call my good buddy to take over! A laid-back slacker becomes a shopkeeper, opens Mary Sue's Shop in the apocalypse, and upgrades it to offer breakfast, lunch, dinner... She is swept along to the pinnacle of life. No wonder it's called Mary Sue's Shop. The moment she opens her eyes, she sees a girl whose kidney has been stolen. Before she's even sold anything, she's already stuffed herself with gossip~ Burp~ She takes it easy and muddles through until the apocalypse ends. The magical Mary Sue's Shop becomes her safe haven, and a lazy fish is born~
