When the apocalypse came, my sister and I accidentally got two systems, one that enlarged the system by a hundred times, and a system that reduced it by a hundred times. My sister smiled and chose to shrink by 100 times, while I could only choose the remaining one. Unexpectedly, after three days of heavy rain, everyone was trapped at home and unable to move, and resources became the biggest problem. I relied on the amplification system to amplify all the supplies I had, saved money and money, and finally got through the difficulties with my sister. Unexpectedly, my sister pushed me off the tall building after the rainstorm.
