My sister and I accidentally got two systems. One is a 100-fold magnification system, and the other is a 100-fold reduction system. My brother smiled and chose to shrink it 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. And I successfully survived the apocalyptic rainstorm with the help of amplified supplies.
