Reborn in the Apocalypse, I Hoard Hundreds of Billions of Supplies and Win

The day I climbed out of the corpse pit, I was reborn. In the last life, my fiancé and stepsister pushed me into the pile of zombies and said with a smile: "Sister, your space power belongs to us." In this life, I activated the god-level stocking system seven days in advance. Selling houses, cars, and jewelry, more than three million yuan were all converted into materials. Rice, flour, mineral water, medicine, gasoline, generators... The five thousand cubic meters of space are packed to the brim. On the day when the apocalypse came, I sat in a fortified house, drinking hot coffee, looking out the window at the people who stepped on my head in the previous life, crying for my father and mother among the zombies. My fiancé knelt at the door and begged me to open the door. My stepsister hugged my legs and cried for sister. I laughed. "In the last life, you also begged me like this. What next?" In this life, I only stock up on supplies and don't save white-eyed wolves. Whoever messes with me will die.
