Chen Jianjun, a technician at the provincial aquatic products institute, resigned and returned to his hometown to take over eighteen mu of abandoned brick and tile kiln pits left by his father, concealing his professional identity to engage in ecological three-dimensional farming. His eldest sister-in-law, He Cuihua, suspicious of property favoritism, creates difficulties at every turn, while village bully Zhao Laomen monopolizes channels and frequently plays underhanded tricks. Relying on superb techniques, Chen Jianjun drills water wells, modifies water quality, and breeds fine crabs, raising top-grade river crabs without a muddy smell at a selling price three times higher than local ones. He takes the lead in establishing a cooperative, building processing plants, expanding supermarket channels, and engaging in rural tourism to lead the whole village to prosperity, resolving knots in his brothers' and sisters-in-law's hearts, and transforming the abandoned kiln pit into the whole village's "golden rice bowl".
