The Seven-Seventies Fishing Magnate: My Island Poverty Alleviation System is an ensemble novel combining the struggles of the era, maritime adventure, and devotion to the nation. In 1974, Lu Yuanhang, a top mechanical engineering graduate, returns from the provincial capital to his hometown on Canglu Island, carrying out his father's final wish. This forgotten archipelago in the East China Sea faces two crises: its fishing commune is on the verge of bankruptcy due to outdated technology, while a covert enemy organization known as "Octopus" plots to steal strategic resources. During a typhoon rescue, Lu Yuanhang unexpectedly activates the "Pearl of the Blue Sea" System, setting out to reshape the island's destiny.
He leads the villagers in starting with repairs to their fishing boat engines, then gradually unlocks the lost shipbuilding techniques of Zheng He's fleet and deep-sea aquaculture technology. With the help of Shen Qinghe, a barefoot doctor, they rescue precious medicines from an underground cold-storage facility left behind by the Japanese army and establish the island's first medical clinic. Together with Lin Wanqing, a fisherman's daughter, he ventures into fluorescent coral reefs and breeds a mutated jellyfish, "Yinghuo," capable of warning of red tides. He also uses a code deciphered by Su Mingwei, an overseas Chinese woman who has returned to China, to uncover a secret maritime defense map left behind by a famous Ming dynasty general who fought Japanese pirates. Meanwhile, the enemy leader "Octopus" poses as a fisheries official in an attempt to seize an undersea volcanic ore lode and blueprints for a titanium-alloy submarine. The two sides wage a battle to the death amid the eye of a typhoon, coral mazes, and undersea volcanic craters.
When Lu Yuanhang harnesses tidal power to activate an ancient coastal defense mechanism, trapping the enemy submarine in an artificial whirlpool, the once-impoverished fishing village has become an ecological strategic stronghold. Floating farms nurture rare seafood, a volcanic hot-spring resort draws international visitors, and deep beneath the reefs, a Zheng He compass found in the wreckage of a Ming dynasty treasure ship points toward an even vaster blue frontier.259 On this land, alive with passion and crashing waves
