During the Tianqi period of Da Qi, on the coast of the East China Sea, the benefits of fishing and salt nourished thousands of families, but there was also a hidden turmoil. Shen Yi, a fisherman girl, was born in the waves and grew up in the wind and waves. She originally wanted to inherit the family fleet, but due to a sudden maritime ban, she saw her father and brother being wronged and the family business overturned. In order to seek the truth and vitality, she resolutely stepped into the turbulent officialdom and business world, dealing with ruthless shipping officials, greedy wealthy merchants and fierce maritime forces. Starting from an old fishing boat, she relied on her extraordinary courage and deep understanding of the ocean to find business opportunities in the stormy waves, and she also made progress step by step in the grand chess game of the dynasty's maritime policy. This is an epic that uses fishing as a guide and the sea as a scroll to depict small people struggling, surviving and becoming strong in the torrent of the times. Not only does she have to control the natural winds and waves, but she also has to face the unfathomable depths of the human heart. In the end, can she weave her own sea map of thousands of miles in the ups and downs of the sea?
