Natural Disasters Turn the Apocalypse into a Wasteland, but Resources Make Me a Landlord

【Wasteland Era + Reborn + Pocket Dimension + Supplies + Community + Farming + Dog】 After the apocalypse, disasters send human civilization into decline: extreme heat, extreme cold, endless daylight, acid rain, and tsunamis. After surviving for thirty years in the apocalypse, he uses a time-space machine to travel back to one month before it began. First, he takes out his cheating ex-girlfriend, then uses his built-in pocket-dimension System to start an all-out stockpiling spree. I’ve got resources, a dog that can play dead, and a cold-faced little beauty who calls me “big brother.” I’ll take people, take money, build a community, and never run out of rice or flour.
