Apocalypse Hoarder's Revenge

Extreme Cold Apocalypse. Past life: deceived by 'goddess' Claire Ford, killed by neighbors. Reborn one month before Cambrian Frost, I awakened a pocket dimension with infinite storage. As a supermarket warehouse manager, I'll empty the warehouse, turning my home into a doomsday fortress. This life, I'll no longer be soft-hearted, living for myself and taking revenge on all who betrayed me!
