In her last life, Lin Wanxing gave her remaining dry food to her "best friend" Su Rou, but was pushed down a high building and became a bait for mutant beasts. Her trusted boyfriend Jiang Chen turned around and took Su Rou to occupy the safe house she had worked so hard to find. Before the flames engulfed her consciousness, she had only one thought - if there was an afterlife, she must make this couple pay for their debt with blood.
Once reborn, she returned to half a month before the apocalypse broke out. There was a space on his wrist that could survive and keep supplies fresh. This time, Lin Wanxing put away all his good intentions and stocked up like crazy: rice, flour and oil filled the warehouse, medicines and equipment were piled to the roof, and canned snacks were enough to last until the end of the world. She even wanted to transform the top floor of the residential building where she had lived for three years into a fortress with copper walls and iron walls. The doors were replaced with the thickest steel plates, the windows were installed with bulletproof glass, and the corridors were filled with obstacles.
The end of the world has arrived as expected, order has collapsed, and a zero-dollar shopping frenzy has swept the city. When Su Rou came to beg her to take her in with a pitiful expression, and when Jiang Chen pretended to be affectionate and wanted to renew their relationship, Lin Wanxing only coldly raised the reinforced security door: "Get out, or die."
Unexpectedly, Lu Shiyan, her neighbor who she had only met a few times in her previous life and who always kept to herself, handed her tools when she was strengthening the fortress and helped her when she was surrounded by mobs. He looked at the mountains of supplies she had hoarded, and there was no greed in his eyes. He only said: "My floor has also been reinforced. How about forming an alliance with the neighbors?"
