Natural Disaster Apocalypse: Reborn, I’m Unbelievably Powerful!

[Natural-disaster apocalypse + reborn + spatial ability + stockpiling supplies + monsters run rampant + ruthless, no saintly protagonist] That day, everyone on Blue Star saw a blinding flash. Then the apocalypse arrived, and one natural disaster after another struck. Scorching heat, extreme cold, torrential rain... Humans and animals began to mutate, too! It wasn't until two months into the apocalypse that Pan Han learned the child wasn't his! His wife teamed up with the neighbor, Lao Wang, and stewed him alive. Reborn one month before the apocalypse with a spatial ability, Pan Han swears he'll never show mercy again! He builds a shelter in advance, obtains trillions' worth of supplies for free, and eliminates dangerous people before they can strike. He won't spare a single person who ever harmed him. Those who are useful to him get fine food and wine. Those who aren't get thrown out to fend for themselves. It's not that he's cold-blooded. The apocalypse is hiding a huge secret...
