[Scandals exposed + heroine's harem + men competing for her + reforming the court + family darling]
The daughter the Minister of Revenue's family brought home has a mouth that knows everything.
On the first day back in the capital, the eldest Su brother's collection of romance stories is confiscated. The second brother's secret stash of a courtesan's undergarments is discovered.
On her first visit to the palace, the truth about a top scholar murdering his wife to advance his career is exposed.
As a result, the Su family's daughter even wins an official post in court, earns the emperor's favor, and sets about reforming the court.
With the emperor's backing, she keeps watch over the words and deeds of every official.
She roots out corruption, catches human traffickers, rescues women and children, and exposes the sordid secrets of the nobility.
Every day, she's either revealing a scandal or on her way to reveal one.
The officials live in constant fear, yet can do nothing to her, so all they can do is steer clear.
Not only does Prince Mo, famed as the living King of Hell, fiercely protect her, but the aloof Imperial Preceptor treats her with respect. The mischievous young heir, known as a little devil, even humbles himself before her. And the foreign crown prince, who looks down on everyone, regards her as a goddess.
