History of Adilson Silva - Pernambuco, Brasil
The world of One Piece is made up of four main oceans: East Blue, West Blue, North Blue and South Blue, as well as a central area called the Grand Line. The Grand Line is known as the most dangerous and challenging route for pirates, as it is where the four cardinal seas and the famous island called Laugh Tale are located, where the One Piece treasure is supposedly hidden.
