The story takes place in the Sixth Street of Xin'an Prefecture, which is full of customs and hidden mysteries. Among the teahouses, restaurants, temple fairs and gambling houses, the carefree Zhao Sanshui accidentally gets involved in the disputes of solving the case. With his natural acumen and humor, he teamed up with the bold and bold Liu Xiang'er, the loyal and honest Ge Shitou and the well-informed Fang Xiaoqi to uncover a series of complex and bizarre cases, which gradually grew from trivial matters to major local cases. Under the influence of good and evil figures such as Pang Zhifu and Lu Wuya, Zhao Sanshui not only cracked the truth, but also exposed the good and evil of human nature, becoming a new legend of "the idle man who solves the case". The four volumes of cases form an independent story, with echoes and clues, a tight overall rhythm, endless puzzles, constant laughter, and a successful ending.
