Seven Kids and Fleeing Famine? My Carriage Has Unlimited Storage

[Fleeing famine + natural disasters + unlimited space + unlimited stockpiling + spirit spring + raising seven children + everyday life + food + zombies] In her previous life, Tian Qiushui used a cart that could hold unlimited goods and expand without limit to protect more than twenty members of her husband's family through the apocalypse for three whole years! In return, her husband had an affair with her best friend, and the two had twins! Her wicked mother-in-law called her three-year-old daughter a burden and pushed her into a horde of zombies! "Did you think you only gave birth to one daughter? You had seven! We secretly sold six of them back then! Why would we need so many burdens?" After learning the shocking truth and growing to hate her husband's family, Tian Qiushui opened her eyes again and found herself back one month before the apocalypse began! She had just given birth to septuplet daughters when her awful in-laws tried the same old trick, planning to sell six of her newborn babies to unscrupulous traffickers for money! Tian Qiushui sneered and pressed a rusty pair of scissors against her scumbag husband. "Either come over and write the divorce papers, or I'll make you a eunuch today!" She kicks her awful in-laws to the curb and makes a clean getaway with her fiercely protective parents and her seven precious daughters! She awakens the [Unlimited Stockpiling Cart System] and empties her in-laws' home within a month! A month later, freezing cold, scorching heat, floods, earthquakes, and zombie hordes strike one after another, turning the world into hell. While her scumbag husband's family runs out of food and water among the zombies, freezing, starving, and kowtowing as they beg her for a scrap of food, Tian Qiushui sits in her luxurious cart, now upgraded into an apocalyptic fortress, holding her seven well-behaved daughters as they drink goat's milk. She aims the newly upgraded rifles and cannons on the cart at her scumbag husband's family!
