After Our Divorce, I Revitalized the Entire Capital with My Treasure Appraisal Skills

In the capital, there is a pawnshop called "Knowing the Subtlety," with strange rules. It asks for no gold or silver, only rare treasures. A bloodstained phoenix hairpin reveals a murder case in the imperial palace; an ancient inkstone stained with tears reveals an examination fraud case; a faded bolt of Shu brocade reveals a treason case on the frontier. Everyone says that the proprietress, Shen Zhiwei, is a divorced woman who has returned with a grudge. Little do they know that she takes in the world's rarest treasures, but what she really plays with are people's hearts and the fate of the court!
