When death should have ended everything, a mistake of the gods drags his soul into another world—an ancient martial realm where the weak are crushed without mercy. Reborn as Sosam, a mute, beaten stable hireling, he lies broken in filth while the world steps on him like dirt.

But inside that broken body lives something far worse. A remnant of Murim Online still functions within him—an inventory, rules, and systems that should not exist in reality. Half human, half system, Dong Bong-su adapts silently, feeding, healing, observing.

This world does not punish monsters. It rewards them. From insects to humans, from stable floors to battlefields, the demon sharpens himself—patiently, intelligently, without emotion.

This is not a redemption story. This is the conception of an unprecedented evil.
