Apocalypse Tycoon: Controlling the Supernatural World with Trillions in Netherworld Currency

The apocalypse arrived, society collapsed, and money became worthless. I calmly opened my banking app, and my balance showed 1,000,000,000,000. My neighbors laughed hysterically at me for clinging to a useless number, never realizing my phone had automatically updated into the Underworld Bank. Stacks of ghost money burned with golden light, summoning countless ghost soldiers and generals. While everyone else trembled before the supernatural, I lounged around, ordering my ghost servants to massage my shoulders and legs. The strongest Ghost King tore through space and arrived, its overwhelming presence forcing all living beings to their knees. It bowed respectfully to me. "Honored majority shareholder of the Underworld, your trillion ghost soldiers have arrived." I smiled and nodded. Excellent. I can keep living like a tycoon in this apocalypse.
