Lu Chen, a bankrupt marine engineer returning to his hometown, originally wanted to seek temporary refuge in Longwan Village, but at the wharf he ran into fishermen being pressed down in price and exploited by local seafood merchant Zhou Hailong. Facing fresh goods about to spoil, he used livestreaming, e-commerce, and supply chain professional capabilities to break the deadlock on the spot. Zhou Hailong's monopoly was torn open, also exposing a deeper network blockade. The wharf, fishing boats, refrigerated trucks, and mobile phone backend became the battlefield for Lu Chen's first battle upon returning home.
