MTL - My Money Kingdom - Chapter 186 : Shouldn't it be in the office... (Subscription required)

Luna Lethal, a name synonymous with fear and power, ruled both the underworld and the elite circles of society. Orphaned young, she rose through treachery to become a master of manipulation and skill. Yet, her reign ended in betrayal—a laboratory explosion claimed her life. To the world, her death was a tragedy; to her enemies, a cause for celebration. But Luna awakens in the body of Aurora Smith, a neglected and ridiculed child despised by her adoptive family. Stripped of her former strength but not her will, Luna faces a choice: seek revenge for Aurora’s mistreatment or forge a new path. As her sharp mind and unyielding spirit transform Aurora’s life, shadows of Luna’s past resurface. Loyal followers sense her presence, while old enemies seek to destroy her again. Torn between vengeance and a fresh start, Luna must confront her identity. Is she still the Devil of the underworld, or can she find peace in a second chance at life?
