This work contains AI-generated assistance content, and the plot is a fictional interpretation. Shen Xiaokuai, a young constable newly arrived in the town, knows no martial arts but has an extremely good memory, relying on observing details to solve neighborhood petty cases. Su Xiaotang, the apothecary's daughter, has great strength and an even faster mouth, taking the initiative to act as his unofficial constable. The two of them go through all sorts of chaos along the way, piecing together fake silver money-laundering clues from trivial neighborhood cases, catching the mastermind behind the scenes red-handed. In the end, Shen Xiaokuai is promoted to head constable, and Su Xiaotang becomes the head constable's wife.
