The Survival Record of Sisters in the End of the World

(The end of the world + rebirth + space + hoarding supplies + cool writing + strong women) I was living a good life, but suddenly I traveled to a parallel world with my sisters. I had just achieved financial freedom after working hard to make money, but the apocalypse came. Permanent day and extreme heat go hand in hand, eternal night and extreme cold at the same time, giant hailstones and ice cones alternate, typhoons bring acid rain... In a hellish apocalypse, no natural disaster comes alone, but comes in pairs, making it difficult for people to survive. An Xi protected her sister Ning Yue, who she grew up with, and survived for ten years in the apocalypse. In the end, she starved to death. Fortunately among the misfortunes, they were reborn again, and each brought their own personal space! With money and space, An Xi must take her sister Ning Yue to live till the end of her life this time! Others are hoarding goods, buying them in boxes and bags, while An Xi is hoarding supplies, coming from warehouse to warehouse! Others are hoarding food, clothes and daily necessities, while An Xi is hoarding minerals and airports in the big valley! It's not that she is willful, it's that her space is so powerful. Not only can she stock up on large amounts of goods, but she can also upgrade and expand her attributes! (Natural disaster, no zombies, mutated animals and plants, no superpowers, all relying on technology, a male protagonist but a doomsday plot, two pairs of CP small groups, and pets)
