Lying Flat and Stockpiling Supplies with Grandma in the Apocalypse

I was reborn with my spatial storage thirty days before the apocalypse. I sold off all my assets and stockpiled supplies, going on a crazy shopping spree for food, snacks, and clothes. Then Grandma and I went to lie flat in our countryside villa and wait for rescue. As Grandma and I ate piping-hot beef tallow hotpot, the scumbag who had raped me and killed Grandma in my previous life was outside my door, dragging himself along on the arms and legs we’d broken, kowtowing to me.
