Luo Lan accidentally activated the pirate growth system, but found that the system did not directly give him strength, but only silently recorded every choice he made. He formed the "Tide Pirates" with his childhood friends and sailed towards the Grand Line to find the legendary "Primary Sea" - it is said that the ultimate secret of why there are waves in the sea is hidden there. They will go through seven sea areas, each sea area represents a "character of the sea", and the ultimate enemy is not an organization, but an ancient force trying to make the sea "still" - believing that waves are a disease of the world, all devil fruits and changes in sea currents must be eliminated, so that the ocean can return to eternal peace.
