The Power Went Out Worldwide, and My Underground City Took Off

The world loses power, civilization collapses, and everyone struggles to survive amid freezing nights and chaos.

But I activate the [Doomsday City Lord System] and gain sole possession of a fully equipped underground city.

When my snobbish uncle's family kneels at my door for a bite to eat;

When the aloof campus beauty who once looked down on me begs for shelter, eyes red with tears;

When the once-powerful rich offer billions just for a place to live...

I stand beneath warm lights, looking down over the darkened apocalypse, and smile as I open the security door:

"Want to come in? Sure. Prove your worth first."
