On the eve of the apocalypse, the two brothers unexpectedly awakened to the dual systems of zooming in and out. In the previous life, the younger brother used the amplification system to protect his older brother, but he was pushed off a tall building by his sweetheart. After returning from rebirth, the elder brother snatched the amplification system first, while the younger brother held the reduction system and plotted secretly. He hoarded supplies, built a secret safe house, shrunk himself and hid in it, and watched with cold eyes as his brother abused the system and caused trouble in order to please his sweetheart Liu Ruyan. In the apocalypse, the elder brother was exhausted by the Liu family and then abandoned, while the younger brother was self-sufficient and stable in the shrinking world. In the end, the rainstorm stopped, the elder brother suffered the consequences, and the younger brother reversed his fate and regained a new life in the aftermath of the disaster.
