Reborn After Death: I Rule the Underworld with a System

In my previous life, I devoted myself to the mob, only to be betrayed by my brothers and manipulated by my lover, then left to die in the street.

Reborn, I return to the days before the tragedy began and unexpectedly activate the Underworld Overlord System.

Recruit followers, seize territory, crush enemies, and trample the big shots. With the System at my side, the world is mine!

Those who bullied and humiliated me will pay a hundredfold;

those who betrayed me will never rise again.

From a nobody on the streets to the king of the underworld, this time I'll rule both sides of the law and dominate the entire criminal world!
