In the ever-changing Age of Discovery, the young pirate Leo led a ragtag ship in the blue sea and sky, firmly believing that freedom and adventure are the real treasures. He worked together with his deputies Susie, Fat Shark, Moore and other partners to tease the rigid officer Jack along the way, snatch treasures from various places, make friends with strange pirates, and battle wits and courage with all forces. In the end, during their journey to pursue the wealth of the legendary Queen of the Golden Ring, they gradually understood the true meaning of friendship and growth, solved the mysteries of the world, and continued to write their own humorous epic.
