Serena, the sole heir to the world's top conglomerate, returned after ten years of covert special training, only to find her beloved older sister dead and her young niece Lily dumped in foster care with the Sterling family — reduced to an abused servant and a "blood bag." To uncover the truth behind her sister's death and rescue her niece, Serena hid her hundred-billion-dollar fortune and infiltrated the Sterling family under a false name as a lowly maid. By day, she was the bottom-rung worker everyone could bully; by night, she was the queen of global capital, holding the power of life and death. Faced with the Sterlings' flaunting of wealth and relentless bullying, Serena maneuvered step by step, crushing them with capital, exposing scandals, and waging a devastating revenge that destroyed her enemies psychologically as well as materially, finally sending the wicked to hell and completing her redemption through family love.
