Eerie Revival: I’m the Underworld Bank’s Major Shareholder

At three in the morning, a game called Hell was forcibly installed on everyone's phone.

[Welcome to the game Hell. Your life is your only currency.]

People were horrified to discover that the ghosts and monsters in the game were appearing in the real world at the same time.

The entire school was trapped inside the classroom building. A slit-mouthed woman blocked the only exit and demanded that they pay with their "lifespan" to pass.

Amid the desperate cries, the school beauty sitting beside me suddenly realized that my phone's interface was completely different from theirs:

[Welcome, esteemed VIP 10 user, to the Hell backend management System.]

[Your current account balance: 999,999,999,999... Netherworld Coins]

[Low-level paranormal entity "Slit-Mouthed Woman" detected disturbing the peace. Would you like to summon the "Netherworld Soldiers" to suppress her?]

Under everyone's astonished gaze, I sighed and showed the Slit-Mouthed Woman my payment code:

"I'll buy your soul."
