The Apocalypse Is Here, and I've Stockpiled a Ton of Supplies

[Apocalypse + natural disasters + goddess + System + passion + ruthless vengeance + no simping] Ten years into the apocalypse, Han Yu risked his life to find food and keep his wife's family alive. One day, zombies broke into their building, and food ran short. His wife's family turned on him, dismembering him and eating him. But Han Yu was reborn, returning to three months before the apocalypse began and binding himself to the Apocalypse Wailing System. Enrage, torment, beat your enemies to a pulp... Make them wail, and you can earn Wailing Points to exchange for advanced supplies like Gatling guns, Barrett rifles, and anti-aircraft cannons. His wife's family can repay the grudges from his past life with their wails... And while he's at it, he'll use his ten years' worth of knowledge about surviving the apocalypse to stockpile just a tiny bit of supplies.
