The sky was dark, with lightning flashing and thunder roaring.
The New World of the Grand Line.
Inside Wano Country, a land of enormous cliffs.
A vast underground cavern.
A gigantic, menacing super-battleship was being rapidly repaired within an enormous dockyard.
The research team led by the world's greatest scientist, Vegapunk, and Water Seven's Galley-La Company, which possessed the world's finest shipwrights, formed the main force here.
The restoration of "Pluton," Pluto, had now reached its core stage.
While everyone in the dockyard was immersed in frenzied work.
At the coastal edge of Wano Country.
A streak of flame like a meteor falling from the sky escorted a small flying island as it transported massive quantities of steel parts to Wano Country.
Boom!!
In the blink of an eye, the flaming meteor landed at the newly built Ironstone Base on Wano Country's coast.
Yet there was no destructive impact.
As the blazing yellow flames gradually gathered into a freckle-faced man.
"Hahaha, Ace, you brat, you almost made us late. Honestly, did you go drinking again?" A hearty woman's laugh suddenly rang out behind Ace after he landed.
"Hmm?"
He sharply turned toward the familiar voice, and a young woman holding a spiked club entered his sight.
"Yamato, hahaha, it's been a long time!!"
A look of surprise abruptly appeared on his face.
He spread his arms wide.
With a boom.
Ace steadily caught the leaping Yamato, and the powerful impact shattered the paving stones beneath them.
Hahaha!!!
Bright laughter echoed across the vast base plaza.
Reunions between old friends were always joyful.
After they had learned about each other's recent circumstances.
Ace handed over the cargo he had escorted to Iceburg, who was in charge of the entire Ironstone Base.
An excited Yamato described the tremendous changes in Wano Country
