Chen Fang was reborn and returned to Shizhou. In order to protect the bay and resist reclamation and pollution by Dongsheng Group, she took the lead in establishing a fishermen's cooperative and building sea urchin breeding and purification tanks. Li Xiangyang, Wang Sili, Owen and others cooperated to expose Dongsheng's illegal sewage discharge and conspiracy. Everyone joined hands to fight against Dongsheng, activate the system, win support from the military, and protect their homes and fishermen's livelihoods. During this period, foreshadowing gradually emerges and small climaxes continue. The protagonist grows through experience and breaks through layers of traps. The plot is compact and full of tension. Military special agents raided the town committee archives at night and snatched the 1987 fishing boat diesel subsidy account book. Chen Fang and Li Xiangyang teamed up with fishermen to hide the core evidence in the secret room of the lighthouse. They accidentally intercepted the receipt signed by Zhou Zhenguo, which led to the Nanyu 307 shipwreck case that had been sealed for many years. The crowd found Lin Xiaohai, the only survivor of the sunken ship, and uncovered the shocking story of individuals in the military colluding with the Dongsheng Group, using the sunken ship to smuggle military fuel, and illegally detaining fishermen. The two sides started a life-and-death game around account books, recordings, and evidence of shipwrecks. Chen Fang used blood as evidence and people's hearts as a shield to confront the evil forces head-on and protect the lifeline of Shizhou waters and fishermen. Chen Fang and others tracked down the plot of the Dongsheng Group and discovered that it forged documents, used "lighthouse" chemicals to control the human body, and deployed sonar arrays. They united fishermen and latent hosts, gradually obtained evidence during confrontations and raids, and launched multiple rounds of games with the enemy. In the end, Chen Fang and others led the fishermen of Shizhou Island to develop sea urchin and other aquaculture industries and island tourism, turning the entire island into a characteristic fishing port and tourist destination.
