Taking place in Medieval Imperial China, during the reign of the Tang dynasty, the player is placed in shoes of the historical Chinese folk hero Di Renjie, a magistrate tasked with uncovering the truth behind a recent string of murders in the capital. As politics surrounding the Empress Wu's recent coronation come to a boil, Di realizes it's not only his reputation at stake...
It includes the following tropes:
- Batman Gambit: The prologue case. Wu and Sun Ying figured that an intelligent but inexperienced young magistrate would be smart enough to put together the clues they left behind, while green enough that he wouldn't think too hard about how tidily he solved everything.
- Da Chief: Essentially Di Renjie's role as the magistrate.
- Dirty Cop: Di's predecessor went around blackmailing suspects and stealing family heirlooms from children to get another spy.
- Disposable Sex Worker: The murderer targets exclusively courtesans, though — this being Ancient China — more than a few of his victims are actually wealthy and well-connected.
- End of an Era: The older generation — represented by Wu's ageing husband and Di's father — have more or less been replaced, and their heirs are still getting comfortable with their new jobs. Naturally, various criminals take this opportunity to pounce.
- Gentleman Detective: Di blends into high society easily, which makes his investigations into their affairs all the more simple.
- Minor Crime Reveals Major Plot: The only reason Di is investigating is because Empress Wu thought the murder of a daughter by the hands of a blind man sounds a little fishy. Or, rather, because she had employed the victim as an assassin that could expose her many crimes.
- Professional Killer: The secret shared between all of the victims.
- Retirony: The Korean ambassador in the prologue was killed just before signing a treaty that would've stabilized relations between his country and China.
