Jiang Anchao worked hard alongside his third uncle for three years, generating two million yuan in revenue but receiving only thirty thousand. His uncle tore up the account books, cut off his sales channels, and turned the entire village against him. Just as his mother fell seriously ill, leaving him overwhelmed by enormous medical expenses, he discovered a camphorwood box left behind by his grandfather. Following an ancient tidal chart, he ventured to the dangerous waters of Black Tide Island, where he found precious seafood and earned the capital he needed to start over. He then took the lead in establishing the Anchao Sea Harvesting Cooperative, helping independent fishing families increase their income. His third uncle joined forces with local merchants to obstruct and suppress him at every turn, but Jiang Anchao and his partners preserved complete evidence and sought legal protection through the fisheries authorities. Along the way, accountant Su Suihe stood by his side, meticulously recording every transaction and safeguarding the livelihoods of the fishermen who depended on the entire rocky shore.
