I Hunt the Reborn in the Apocalypse

(Apocalypse + Reborn + System + No harem, no womanizer + Smart protagonist + No goody-two-shoes + Building a faction) + (While the neighbors stockpile food, I stockpile guns. The neighbors are my pantry.)

The apocalypse arrives, and everyone's a reborn protagonist or someone who transmigrated into this world. Are there even any locals left?

One after another, they come back reborn or transmigrate here. They were idiots before they were reborn, but now they're all Einstein, huh?

Every reason for being reborn or transmigrating involves getting cheated on. Isn't that getting old?

For the sake of keeping the world stable and the apocalypse running as it should, I'm sorry, everyone.
