Oh, this question is very challenging! Firstly, I would recommend Detective Dixson. This novel was a classic detective novel with a lot of secret room plots and strict reasoning logic. It was very worth reading. The second was "The County Magistrate's Sweet Pet: My Female Constable's Reasoning." This novel was a mystery novel from ancient times. The plot was exciting, and the female protagonist was a very powerful female constable. It was very worth reading. Finally, I would like to recommend a novel from the small Shanhe County,"Late Night Strange Talks." This novel was relatively short, but it was very compact. Every secret room case was a hilarious joke. I hope you like this fairy's recommendation. Muah ~😗
