On the day his engagement is called off, Jiang Chao unexpectedly gains the ability to share vision with seagulls, allowing him to see through seawater and search for fish schools everywhere. Taking a boat out to sea, he hauls in two hundred pounds of golden pompano in a single net, and subsequently discovers abalone, sea cucumbers, ambergris, and deep-sea sunken treasures. From a young man mocked by the entire village to buying large ships, building a fleet, and opening up seafood sales channels, he rises against the odds all the way and also wins Haitang's true heart. In the end, leading partners such as seagulls, sea turtles, octopuses, and whales, he sails toward the Arctic to harvest king crabs, turning his daily life into a legend of the entire ocean.
