My Sister Has Space Powers and Helps Me Stock up on Billions of Supplies.

(The end of the world + rebirth + crazy hoarding of supplies + not the Holy Mother + building a force) The end of the world is coming, and the world has entered a cold wave period. Hundreds of millions of people have died of cold, and billions of people have died of hunger! Fifty days later, the cold wave mysteriously receded, the global climate returned to normal, and people ran out of their homes happily. Even more terrifying things happened. Thousands of creatures mutated into terrifying monsters. People who died in the cold wave were mysteriously resurrected and turned into zombies! Zhang Ling and his sister survived the cold wave era, but unfortunately died in the zombie wave. Ironically, before dying, he and his sister awakened their special powers! With reluctance, Zhang Ling returned to the pre-apocalyptic world. This time he wanted to stock up on hundreds of millions of supplies to live comfortably in this apocalyptic world!
