Rebirth Stockpiling: The Little Girl Sweeps Through the Apocalypse

[Post-apocalyptic + System Space + Stockpiling + Base Building + Strong Female Lead + Reverse Harem + Not a Mary Sue]
Who says a five-year-old can only be a burden?
Yun Xiaoxiao, a formidable survivor in the post-apocalyptic world, is reborn six days before the apocalypse hits. Unloved by both parents and unwanted after their divorce, she decides to take matters into her own hands.
At just five years old, she goes on a rampage. She empties out her father’s supermarkets and 4S car dealerships, landing him in the hospital.
Armed with a super system in a world ravaged by zombies, extreme temperatures, and acid rain, she hoards enough supplies to last several lifetimes. She becomes a base-building maniac, constructing the strongest fortress in the post-apocalyptic world.
Sunny Boy Next Door: “Little one, want big brother to sing you a lullaby?”
Unlucky Bandit: “Kid, what do you want? I’ll get it for you.”
Cool Big Brother: “Don’t be afraid. I’m here.”
Yandere Hottie: “Little one, call me big brother and I’ll kill them all for you. How about that?”
Hot-Tempered Brawler: “Shorty, who’s bullying you? I’ll beat them to death!”
…
Yun Xiaoxiao hastily raises her hand, “Stop, stop! I can take on ten at once!”
“Whoever dares to bully me, I’ll finish them off myself!”
(This story has no romantic pairings. Readers who mind this, please be cautious.)
(The female lead appears innocent on the outside but is actually a wolf in sheep’s clothing. Her personality was shaped by the post-apocalyptic world, growing beyond the bounds of normal rules. So she’s a bit ruthless, a bit wild, a bit wicked…)
