On the eve of the apocalypse, my sister and I were bound to a dual system of zooming in and out. In my previous life, I relied on the amplification system to protect my sister for five years, but she pushed me off a high building for my pet. After rebirth, my sister took away the amplification system first. I resolutely chose to shrink the system. I stocked up on supplies before the end of the world, shrunk myself and my family property, and hid in the secret room of my bedroom to build a mini farm. The younger sister was obsessed with love and relied on the system to please the Zhuma family. In the end, she was abandoned because the system ran out of value, and she met a tragic end. And I was self-sufficient in the secret room. After five years of torrential rain, I finally regained my life at the end of the apocalypse, completely getting rid of betrayal and shackles.
