Doomsday Rebirth? I Took My Little Local Dog and Stocked up on Supplies Until It Was Full

Strong male and female protagonists➕No bloody love plot➕No mother's heart➕8 apocalyptic states➕New doomsday upgrade➕Compact plot twists. I like doomsday novels without zombies. There are many conflict scenes. I hope the male and female protagonists will become stronger and stronger. The author hates stupidity. Stupid people can't survive for 3 days. Please support me!
