After Franky was done with the repairs to the canon, the entire crew loaded the 1000 Sunny into the Space Cannon. On the opposite side of the island where they docked, there was a stream that into the rocky mountain in the center of the island. This is where the cannon was located.
"Alright," Jinta said. "The canon works by sucking water from the sea, pressurizing it, then releasing it full blast. It also has a lot of technology from the stars in it. So it's gonna have some nasty shock when we're fired."
"Zoro, are you sure you don't wanna come?" Luffy said as Zoro exited the cannon.
"Nah," Zoro said. "Someone's gotta stay here and watch over these kids. Tell me how it goes." He walked outside and shut the hatch to the cannon.
The island's kids operated the control panel to the cannon. "Are the canons primed and ready?" One of the kids said. The others nodded as the pulled some levers made of wood and a huge cannon popped out of the mountain. Three kids rotated a crank that pointed the cannon straight upwards.
"LUFFY!" Ussop shouted to Luffy. "Jinta said that we would want to go below the deck and strap ourselves down, come on."
"No thanks," Luffy said, sitting on the figure head. "I'm fine."
"But," Then the cannon started to rumble and the water below them started to boil. "Suit yourself!" Ussop ran below deck.
Luffy used one hand to grip the figurehead and used the other to hold on to his straw hat.
"All ready!" The kids shouted. "Firing in 3...2...1...FIRE!" and as they shouted fire, the canon shot a burst of steam and the 1000 Sunny was shot from the canon and sent hurtling through the sky into space.
Luffy tried as hard as he could to grip on to the figurehead, but his arms stretched until he hit the wall of the cabin. If it wasn't for his rubber like body, Luffy would have broken straight through the planks because of the g-force. But instead his body just flattened on the wall of the cabin.
The 1000 sunny finally came up on what seemed like a small river of stars. Everyone came above deck and stared in awe at the sight of space.
"It's beautiful," Nami said. "And so big. Think how many maps I could make."
"No use trying," Jinta told her. He went to the side of the deck and pointed to the stream of stars they were sailing on. "This is the only place where ships can travel on. Made by the star people. It has its gravitational pull and air field. Stray from it and you'll find yourself falling through space."
"That's very interesting to know," Robin said, taking notes.
"Just follow this stream and we should come to a port."
The Thousand Sunny docked at a large metal disk floating in space. There was a wooden dock there like on Earth. Strawhat Crew pulled up and tied to ship down there. The entire crew was amazed by the sights on this dock. There were huge metal buildings of all colors stretching up for miles. Glowing lights were everywhere. Flying ships passed overhead going in every which direction.
Franky couldn't believe all of the machines and devices that were around him. It made the 1000 Sunny look like a pile of rocks. It made his own robotic enhancements look like child's play. "It's all, so much better than what I can do." Franky sighed.
"Yeah," Ussop said. "It sure is." Everyone hit him over the head. "What? I was just agreeing with him!"
"THAT'S NOT THE KIND OF THING YOU AGREE WITH!" Nami yelled. She turned to Franky. "Don't listen to him Franky, you're an awesome engineer. I bet with a little learning, you could learn every secret of these people's machines." She smiled and Franky did too.
"Oi, check out these weird people." Luffy pointed to the people that were running about the dock. They were shaped like normal humans, but they had skins of all colors, horns and antennas coming from their head, and other features like wings and extra arms. Luffy laughed. "They sure are funny."
"They're the people from all over the stars." Jinta explained. "To them, you're just as funny looking as they are to you." Then the group saw a horrendous sight: smaller star people being whipped and forced to do work by larger ones.
Nami gasped. "That's horrible!"
Jinta sighed. "They're slaves. They were legally bought by their owners. Don't do anything, you'd be breaking the laws. And if you do that you'll…" But Jinta noticed that Luffy was ignoring him and walking straight to the slaves. "HEY YOU DUMBASS! I SAID DON'T DO ANYTHING!"
"LUFFY!" Brook shouted. "YOU SHOULD LISTEN TO JINTA!"
But Luffy was already at the slaves. He walked up the owners. "Hey, you. You shouldn't force people to work like that."
The huge space person laughed. "Says who?"
"Says me." Then Luffy did an uppercut to his face.
The huge space person staggered back and grunted. "Ugh, you're just asking for me to kill you!" He charged at Luffy, but was intercepted by a large robotic man.
"Halt," It said. "Stand back, we shall take it from here."
"They're the law enforcement," Jinta explained.
"Life form identified as Monkey D. Luffy, species human, planet Earth, wanted criminal, bounty 300,000,000,000. Taking him in and preparing to turn him over to the authorities of his home planet." The robotic walked away with Luffy in its hand.
"HEY LET ME GO YOU UGLY HUNK OF METAL!" Luffy yelled while thrashing and trying to get free.
Nami sighed. "Guess we gotta bail his ass out again. Come on guys." As the group took a step, they were caught in a blue light. "WHAT THE?"
"IT'S CAPTAIN BLASTER!" Jinta shouted as they were pulled towards a large flying ship. "HE'S TAKING US AS SLAVES!"
