Apocalypse Rebirth: Stockpiling Supplies Like Crazy

【Rebirth + Apocalypse + Stockpiling Supplies + Upgradable Pocket Dimension and Farming + Strong Female Lead】 She spent five years surviving the apocalypse, living in constant misery. During a team mission to search for supplies, someone ambushed her, cut out her crystal core, and tossed her body into a horde of zombies to become their food. Who could have guessed that when she opened her eyes, she would be back one month before the apocalypse, with a pocket dimension at her disposal? She could hunt down the mysterious person who stole her crystal core while frantically stockpiling supplies. She could do both at once. The farming space had a thirty-to-one time ratio, and could be upgraded, greatly increasing the speed of cultivation. Plant melons and reap melons, plant beans and reap beans. It could even be upgraded, and living creatures could enter. How great! Who cares? Cows, sheep, chickens, ducks... seafood, all of it goes into the space! After the apocalypse begins... Books scattered around the major libraries? Hey, they'd just go to waste here. Into her space they go! Find a seed shop? Take it, take it, take it. All kinds of snacks? Take them! Daily necessities? Take them! Household appliances? Take them! Take it all. Whether she needed it or not, she was taking it. With all these supplies and a space where she could grow crops, she refused to believe she couldn't lie low until the end. Who would have more supplies than she did? No one! Most importantly, she was going to take out the people who stole her crystal core. (This story is entirely fictional.)
