Extreme Disasters in the Apocalypse: What’s Wrong with Me Bringing a Little Extra?

On the day of the extreme-cold apocalypse, her stepmother and younger sister leave her to freeze to death outside the door. Her father watches without lifting a finger as people devour her until not a bone remains! Reborn before the apocalypse begins, she has a space with a spirit spring and frantically stocks up on supplies, plants vegetables, and stockpiles even more.

Step by step, she turns her little apartment into the strongest fortress in the apocalypse.

"Sis, your dad and the others are here again. Should we let them in?"

"Good girl. Beat them back out!"
