My sister and I awakened two systems at the same time, one is a hundred-fold magnification system, and the other is a hundred-fold reduction system. My sister smiled and chose to shrink a hundred times, and I could only choose the remaining one. I never thought that the apocalypse would come after three days of heavy rain, and everyone would be trapped at home and unable to move, and supplies would become the biggest problem. I relied on the system to amplify all the supplies I had, and finally got through the difficulties with my sister. Unexpectedly, just after the rainstorm ended, my sister pushed me off the tall building!
