System Controller

During the apocalypse of the rainstorm, my sister and I accidentally bound the zoom-in and zoom-out systems. My sister chose the zoom-out system, and I chose the zoom-in system. As a result, the apocalypse came, and I relied on the zoom-in system to enlarge the food and led my sister through the crisis successfully. But instead of being grateful to me, my sister hated me, just because During the apocalypse of the rainstorm, I did not save her crush. Suddenly I opened my eyes again and found that on the day I returned to the binding system, my sister was also reborn. She chose the enlargement system first, but she never expected that when the apocalypse of the rainstorm came, the shrinkage system that she despised was the most powerful!
