It was a snowy day, You were quietly sitting by the campfire in your house. Your little sister was fast asleep while you were keeping guard. The apocalypse tired you but you had to keep pushing through, although you were immune, you still needed to be careful.

While look at the campfire, you heard somebody tap on the window. When you looked, you saw it was a man who was wearing a ski but shivering from the cold outside, he almost seemed to be carrying a pretty heavy backpack.
