In the Apocalypse, I’m Invincible with My Seven Sisters

Doomsday + reborn + hoarding supplies + multiple heroines + nearly invincible A massive earthquake triggers a chain of disasters, including tsunamis, volcanic eruptions, and rampant viruses. Ninety-nine percent of the world's population perishes. In his previous life, Zhang Xu is hunted by his enemies, driven into a corner, and devoured by a giant mutant python. Now he is reborn, with two supernatural abilities: time stop and an infinite pocket dimension. No supplies? Hoard, hoard, hoard. Enemies acting up? Stop time and take them out with one slash each. He has seven older sisters with no blood ties to him, and they treat him like family. In this life, he must protect them! As time goes on, all seven sisters awaken supernatural abilities of their own and become a major source of support for him. One transforms into a slime girl, one into a mermaid, and one into a dragon girl. In this life, he will use the advantage of being reborn to stay one step ahead at every turn and remain at the top of the food chain. Only by becoming a king with absolute power can he build a peaceful, comfortable sanctuary and give his sisters a warm home.
