Catastrophic events occurred, and the world underwent enormous changes. First, extreme heat, then extreme cold, followed by earthquakes, heavy fog, eternal night, and acid rain in quick succession. Nina struggled to survive alone in the apocalypse for ten years, but in the end, she died in the pouring acid rain. When she opened her eyes again, Nina realized that she had been reborn, and there were still three months before the apocalypse. After discovering a huge personal space in her family heirloom, Nina set her first goal after rebirth – to spend 2.1 billion and fill up the space with goods! From then on, Nina began hoarding. Rice, noodles, and cooking oil? Buy! Chicken, duck, fish, and meat? Buy! Clothes, hats, shoes, and socks? Buy! Dried meat, chicken feet, small hot pot, potato chips, spicy strips, and snail noodles – not a single one could be missing!
