Lin Xia was tricked by her boyfriend Zhou Hao into a deep-sea shark cage for murder and insurance fraud. Near death, she was granted an ocean illustrated guide by the Sea God, unlocking various marine creature abilities. Relying on her abilities to harvest sea treasures, she helped her family pay off high-usury debts and met Huo Yan. Zhou Hao teamed up with Bai Ruolin to repeatedly suppress her. Lin Xia went out to sea to harvest countless rare seafood, accidentally salvaged a Ming Dynasty shipwreck national treasure and voluntarily handed it over, and was rewarded with an ocean-going giant ship. In a storm, she saved her enemy Huo Feng, and finally her career soared, running towards a two-way romance with Huo Yan.
