After a sudden upheaval leaves her stranded on a deserted island, the adult heroine Yuan Jin refuses to lose heart. Drawing on her previous life's experience in marine aquaculture, she gathers and processes seafood on the island, leading her family to build a trading house from scratch. She opens up maritime trade routes, gathers evidence, and returns to the capital. Through lawful means, she exposes the conspiracy and clears her family's name. Ultimately, she gives up official honors, sets sail, and expands overseas trade routes, venturing alone across thousands of miles of blue ocean to write a legendary story of an independent woman's struggle and success.
