The Crippled Bigshot's Little Ancestor Is Too Cool - Chapter 6

THE LAST MARINE– Series SynopsisThe world ends not with a bang, but with a prayer and a shattered test tube. Marine Quinn Calloway, a man accustomed to the structured chaos of war, finds himself on leave in the deceptively peaceful mid-sized city of New Havenburg when the unthinkable happens. Dr. Lucian Kael, a brilliant and devoutly religious scientist at the prestigious Blackwood Research Institute, driven by a fervent desire to unlock humanity's “divine potential,” makes a catastrophic miscalculation. His experimental “Kael Strain” virus, designed for benign purposes, is accidentally unleashed, and its effects are swift, brutal, and biblical in their apocalyptic scope.

“I want to be a true demon.”

A boy not older than 20 years wished as he looked at the sky.

After suffering from the trauma for many years, he finally gave up on life.

People called him ugly, demon, and hideous.

He bared with it, but today he finally broke.

With a piercing pain in his chest, he died.

When opened his eyes, Logan found himself in another world and inside the body of a demon.

His wish was granted, but at what cost?

He had no power and was the lowest among the demons.

No one to help, no one to be with him.

But it did not affect Logan. Because he had something else with him.

‘Sin and Virtue System.’

Guiding him towards his goal to become a true Demon.

Logan’s conquest has begun, so be a part of it.

Otherwise, you will miss him.

The true Demon!

However, is the MC the 'only' one to have a system?

Hm?

Read the fucking novel and find out!

I was reincarnated into another world, and I’ve brought the Horadric Cube from Diablo II with me.
Being a knight is cool and all, but being a wizard is pretty neat as well.
So, which one will it be?
