Apocalypse: Plundering the Protagonist's Fortune from the Start

An apocalypse story. The protagonist isn't reborn or transmigrated, and can't foresee the future.

But by chance, he awakens a power to plunder from the start!

Why are a few guys always picking on me for no reason?

What? Those guys were reborn and transmigrated back from the future?

The world's about to end?

How could that be?

Those guys have definitely got something wrong with them!

How could the world end in this prosperous age?

Is that guy mentally ill?

If I plunder him, will I take his mental illness too?
