My brother and I accidentally acquired a 100x magnification and 100x reduction system. In my previous life, my brother saved his childhood sweetheart Lu Yao's family because I didn't use the magnification system. After rebirth, my brother chose the zoom-in system first, while I chose the zoom-out system. Knowing that the end of the world was coming, I made preparations in advance and purchased food, furniture, wind power equipment and other supplies online. I also used the shrinking system to create an exclusive safe room and small farm to fully prepare for life in the end of the world.
