Kokyu Shingan Hantei Nin

title
In the Liuquan Kingdom's Flying Wheel, Nogi, who runs the antique and calligraphy shop "Frozen Butterfly," is asked by her best customer, the nobleman Xiuqing, to become the "authenticity judge" of the imperial harem. The harem was extravagant under the previous king who died several years ago, but the current King of Liuquan plans to abolish it eventually, so it is currently on a smaller scale. However, the king fears that the remaining consorts of the previous king are constantly being approached by merchants selling dubious items, which could become a source of trouble. Therefore, Nogi, who has a reputation for being able to discern the authenticity and deception of not only documents but also various other things, has been chosen for the job. When Nogi heads to the palace, she meets a young man named Fenglang who is looking for an official position, and together they face various mysteries and strange events!
