Before the apocalypse came, my brother and I were reborn at the same time, competing for the dual systems of zooming in and zooming out. In my previous life, I used the amplification system to protect my younger brother through the apocalypse for five years. However, I was resented and betrayed by my younger brother because I refused to help my childhood sweetheart return to the Chu family. In this life, my brother was the first to take away the amplification system, while I chose to shrink the system, hoard supplies in advance, and build a secret room farm for self-protection. The younger brother was obsessed with Shen Ruchu and exposed the system to make money. He was eventually abandoned by the Shen family due to exhaustion of resources and starved to death in the chaos. And I relied on the downsizing system to live a stable life. After five years of torrential rain and the apocalypse, I finally succeeded in surviving and ushering in a new life.
