In the winter of 1976, Shen Jichuan of Baishawan Village suffered a broken leg and faced harsh treatment from his in-laws' family, while even half a corn bun belonging to his daughter was snatched away. On the verge of dying after falling into the sea, Cang Lan, the injured dragon god he had saved years ago, appeared to repay the favor, bestowing upon him the dragon essence and dragon pupils. Relying on the dragon god's help, Shen Jichuan repeatedly hauled in massive catches when going out to sea, managed with difficulty to split from the family and establish his own household alongside his wife, resisted his greedy eldest brother's family, and relied on seafood and marine product processing to ensure his entire family had enough to eat and wear warmly, allowing his daughter to attend school and read books as well.
