In the golden age of navigation, Leo Flynn and a group of partners with different personalities set sail on the horn of the "Liberty" and broke into the dangerous waters to challenge imperial warships, cunning pirates and mysterious seas. They support each other, use courage, humor and wisdom to resolve crises, gain true friendship and growth, and face the temptation of gold and the price of chasing it. The three volumes of chapters reveal their journey from unknown pirates to legendary heroes, to a twist of fate and finally self-redemption. In the irony and joy, a grand picture of a free sea adventure is gradually drawn.
