After being driven out, I return as a queen ten years later

Victoria is the illegitimate daughter of a southern port logistics tycoon who was expelled by her family and secretly built the world's top military force, 'Obsidian.' When her father suddenly passed away, she returned to New Orleans, using absolute force and intelligence to crush her second uncle's family's plot for power, exposing crimes such as perjury, money laundering, and murder, driving the lawbreakers to the brink. During this period, she influenced her brother Leo, protected her sister Chloe, repelled numerous external interferences, and ultimately successfully took over Crescent Bay, crowning herself as the absolute mistress on the ruins of her family.
