The Oriental Dragon Kingdom established a "Special Investigation Team for Intangible Cultural Heritage Suspense Cases" and recruited a group of geeks who use scientific interpretation of ancient laws. In the first volume "Cinnabar Red", they used the ink pad of a seal to reveal a legacy tragedy surrounding the palace's secret recipe. Since then, "Bronze Corpse", "Porcelain Shadow Knife", "Loom Curse"... Every strange case is a route to a cultural lighthouse that is about to extinguish.
