Global Freeze: Automatically Sign in Every Day to Obtain Supplies

In the icy apocalypse when a blizzard covered the world, I activated the [automatic sign-in system]. Types of sign-in rewards include but are not limited to: food, items, weapons, house enhancements and improvements... As I checked in for a while, I was rewarded with the ability to move the entire residential building. So, I transformed the entire building through the system and cleared out all the residents in the building. I controlled the building to move in the snowstorm, preparing to pick up my parents and sister who were trapped in other cities by the snowstorm.
