If he and his workers can build the new island, it will not only be able to sail in the ocean but will also have all the amenities that Water 7 was known for plus some extras. The island ship, if built, could also be in the air for some time if it was built correctly.

Franky had given him the theory of nuclear fusion, but it was too hard to build one. But even without nuclear fusion, it would travel a long distance and be in the air for some time. This would be one hell of an island if it was built properly.

Iceburg couldn't believe it at first when Franky came up with the designs, but now, looking at Merry, he totally believed Franky's words. He knew that something might have happened when the Straw Hats took him away for some time, but since it was a secret of the Pirates, he didn't ask more and was happy with the results.

The port was soon opened, and the new Merry didn't take long to slowly take off. The ship thrust its jet engines, which were lodged on the underside of the ship. It generated a huge gust of wind, so everyone had to get away from the ship. But the people around them still waved at the Straw hats.

Unlike the departure of Franky, which gathered many people around, this time there were fewer people around and only those who actually knew what went down after the Aqua Laguna. The Galley La had done an excellent job of hiding what went down in the lower part of the city, but it also made the Galley La grateful to him.

They all shouted at the top of their lungs while the ship slowly flew away. The people in the city also got to see this huge ship with their own eyes as it was flying at a slow speed. Slowly, they crossed over to the ocean, and this was where Garp and his subordinates got to see the flying ship for the first time.

Suffice to say, they too were surprised to see the flying ship.

"GRANDPAAA... I hope you have a wonderful journey ahead." Luffy, being Luffy, shouted as he saw Garp in his ship below.

"How dare my grandson be above me? Let me knock this ship down." Garp shouted. Helmeppo and Coby had to go and stop him again.

"GRANDPAA... Don't sweat on it. Our ship can fly for longer than yours. Tell Vegapunk to update his technology or else he will be left in the dust." It was Ken who shouted this. He knew that the ship of Garp could momentarily fly, thanks to the machinations of Vegapunk, but there was still nothing in front of their ship, which could just remain in the air.

Garp was more angry, and a stream of vapor came out of his nose as his other grandson made fun of him and his ship, which he loved. He didn't care about how his grandson came to know of the ship's flying capabilities.

But he was also a little taken aback by the grandeur and size of the ship. He could also see the cannons on the sides and even the front cannon. He had a feeling that the front cannon would be devastating if it was ever unleashed.

"Franky, what do the front two cannons do?" Ken asked. Merry's figure on both sides had long horizontal stick-like things. But Ken had a feeling that this was just a couple of rails.

"This is not a cannon. But a railgun. You know what a railgun is. Right?" Franky said that, and his red eyes blinked a little when he said that. It signified how excited he was to talk about this topic. He went on to explain what a railgun was.

But sadly, not many were interested in this, and only Vivi and Robin listened to him attentively. Ken was just surprised that Franky was even able to mount a railgun on the ship.

"This can destroy an island as big as Water 7 easily."

"What?"

"Nani?"

"What the fuck?"

"Are you serious?"

The people who were dozing off when Franky was explaining woke up with a start, including Luffy himself. They had their eyes wide open.

"This thing can destroy an island?" Ken asked, as he too was taken aback. Franky gave it a thumbs up.

"Franky, You have outdone yourself." Sanji said. Everyone praised him when Franky admitted to being an island killer.

"Onigashima will be a fun ride this time." Ken thought to himself, Meanwhile, the ship had picked up its pace and vanished into the horizon. There was no throwing of cannon towards their ship, so it was all safe and happy goodbyes to Coby, Garp, and Helmeppo.

The ship started sailing again. With a new member and new bounties. Now their bounties were high enough to rival those from the New World. It might not be on par with the overlords of the New World, but it was enough to inflict fear on any normal navy.

After going quite a distance, the ship settled on the sea and started sailing just like any other ship. But this wasn't just any other ship. This was a megaship that was sailing in luxury. Nami had used magic on the ship and had made the rooms much larger using the stretching spell. The ship was now more luxurious.

Plus, she had also put an invisible charm on the ship. According to Franky, the ship could never be detected on the radar of any other navy ship, and due to the charm, until and unless one ship came closer to their ship, they wouldn't be able to even see it.

Of course, if someone had Haki, it was a different question, but in general, it was almost impossible to find their ship.

"So the next island is Fishman Island?" Nami asked as she saw the pointer slowly pointing under the sea as they traveled.

"Yes. But we will need to coat. This ship can't handle so much pressure. I have already talked with Kokoro grandma."
