Reborn in the Apocalypse: Building a Top-Tier Safehouse from the Start

Apocalypse + rebirth + System + technology + stockpiling + base + pocket dimension + supernatural powers] Setting: Vast stretches of ocean are polluted, and the contamination spreads throughout the global ecosystem. Marine pollution worsens, fish mutate, torrential rains batter the world, and humanity's drinking water is contaminated. Driven by atmospheric circulation, ocean pollution triggers mutations throughout the global ecosystem. With the situation beyond control, people drink polluted water, their bodies break out in sores that fester with pus, and soon their nervous systems are attacked, turning them into zombie bros... One day, ocean pollution brings catastrophic destruction. The world suddenly grows colder, plunging into a primitive ice age. The frigid apocalypse arrives. Eighty-eight percent of humanity perishes, while the remaining twelve percent evolve again and fight the zombies. Extreme cold, tsunamis, extreme heat, endless night... In her previous life, Su Yan was blinded by love, and the person she loved pushed her into a horde of zombies. Reborn on the night before the oceans become heavily polluted, Su Yan awakens her spatial ability and begins frantically stockpiling supplies! Short on supplies?! Then we'll sell, buy, borrow, and take out loans! The outside world isn't safe?! Then we'll build a secure hideout where people can shelter, a super, invincible safe house that even missiles can't destroy!
