After saying goodbye to Aizen, Naruto went to find Wolffy.
Wolffy was still holding his Hammer Wrench, hammering away at the machine in front of him.
The machine was none other than the Dimensional Shuttle he had invented.
"Hey, Wolffy, how's the research on the Dimensional Shuttle coming along?"
At Naruto's question, Wolffy replied without even looking up, "I've made progress. The biggest issue now is pinpointing the coordinates between worlds!"
"Once I get the coordinates right, we can start testing!"
Just as the Naruto world had countless parallel worlds, other worlds had all sorts of parallel worlds too. Traveling to a specific world required a way to pinpoint it.
Naturally... Wolffy had already figured out what to use as an anchor: people who came from the Sealing Space.
By using them as anchors, he could connect to the worlds they originally came from.
It was just like how Wolffy had used himself to connect to his own world and bring Red Wolffy and Little Gray over.
"Wolffy! Hammer together a rocket for me when you get a chance, will you? I want to take a trip to the moon."
Hearing Naruto's request, Wolffy pointed at the room next door. "I finished the rockets ages ago. Go take a look yourself and fly whichever one you like!"
Naruto: ...
Naruto gave him a thumbs-up and grinned. "King Wolffy, you never let me down!"
This time, Wolffy didn't look particularly pleased with himself. Seeing his state, Naruto knew he must have hit a snag... so he stopped bothering him and headed straight into the next room.
The room next door held three rocket launchers. The bases, launch mechanisms, and even the fuel were all ready. All they had to do was climb in, and they could launch straight to the moon.
