Returning home after completing her studies to take care of her family, Lin Qingyan accidentally falls into the sea and gains clairvoyant X-ray vision, allowing her to see clearly through underwater fish schools, reefs, and hidden secrets. The fishermen of Lanhai Town have long been jointly suppressed by local fishmongers and provincial aquatic capital, who illegally occupy shoals, engage in illegal fishing, blockade logistics, and constantly harass the villagers. Keeping the villagers close to her heart, Lin Qingyan relies on her perspective ability to discover high-quality fishing grounds, collect various violations and illegal evidence, cooperate with maritime regulatory authorities to rectify maritime chaos, and found an ecological fishery cooperative. Facing layer upon layer of capital blockades, she bravely ventures into the dangerous deep sea to open up brand-new fishing grounds, completely breaking the market monopoly, bringing stable income growth to fishermen throughout the village, and protecting the azure sea and the local people.
