In the apocalyptic disaster, which has been characterized by high temperatures and heavy rains for several consecutive years, the system gave me three skills and asked my sister and I to choose fixed repetitive action marks. My sister snatched the last two skills before me, and I silently picked up the first function. In the apocalypse, when water and power were cut off, I directly activated the fixed skill to stick all the food in vacuum packaging to keep it fresh. When the zombies came, I activated the skill again, sealing the doors and windows 100% to create a perfect safe house!
