In the Age of Discovery, the true identity of young Roy Green is a mystery. He gathers a group of partners with different styles and distinctive personalities, vowing to create their own legend at sea. They drive the "Star", pursue the legendary golden treasure, and compete with various pirates, royal fleets, and conspiracy forces. Crisis and opportunity coexist, and humor and wisdom become their greatest weapons. In the three-volume story, they grow from a rough team to a maritime legend, but their beliefs and dreams are repeatedly tested. In every laugh, there are tears; in every recklessness, there is growth. In the end, who can harvest gold and freedom, and who will be lost in power and desire?
