Feasibility of Landing on the Sky Island

Onboard the Yomi.

Captain Brook, combatant Redfield, sniper Silvers, navigator Shakky, shipwright Tom, intelligence officer Antonio, pets Memory Seahorse and Wuzhu, mount Qilin Lion, and the island whale Laboon, who towed the ship.

They sat together in a circle, celebrating the anticipation of their voyage; from this day forward, they were comrades who would face life and death together.

"Captain Brook, are we truly setting sail for the New World this time? Almost all of this year's Supernovas have already reached the Sabaody Archipelago, and powerhouses like Golden Lion Shiki have long since ventured into the New World."

Shakky was impatient to see just how terrifying the legendary, perilous New World truly was!

"Without strength, entering the New World is just asking to be served as a meal. Everyone must hone their Haki and Six Powers. Our target is Jaya Island, the legendary Golden City.

Moore Thomas has already relocated the headquarters of the World Economic News Agency there. Our goal is to conquer the Sky Island and secure it as our base of operations."

"Captain, does the legendary Sky Island actually exist? Are you sure you haven't been deceived?"

Silvers had always been skeptical of the legend; after all, he had heard plenty of stories about the liar Noland.

"The other half of Jaya Island, the Golden City of Shandora, is real. Three or four hundred years ago, it was blasted into the sky by a massive Knock-Up Stream. It is also true that there is a vast amount of gold up there!"

Brook spoke to his crew with earnestness, his serious expression leaving no doubt that he wasn't pulling their legs.

"Then wouldn't we be rich? Is this the great treasure of the Golden City?"

Shakky said excitedly, as if she could already see herself draped in gold and silver, becoming the world's wealthiest tycoon.

"Wealth is a certainty. I intend to bring the World Economic News Agency into our sphere of influence and move it to the Sky Island. Furthermore, there might be technology on the Sky Island for building flying ships—I just don't know if that specific Devil Fruit is still there."

Brook wasn't sure if the Rumble-Rumble Fruit had respawned on Birka Island. If not, he wondered if they could use a large number of Breath Dials and Thunder Dials to achieve short-term flight.

It was also time for Tom to get his hands on the blueprints for the Ancient Weapon Pluton; he wondered if Tom could use those designs to create a propulsion device similar to a Wind Roar Cannon.

"Captain, what Devil Fruit are you so focused on? The Rumble-Rumble Fruit you mentioned by chance?" Shakky asked curiously.

"Correct, the strongest Logia-type Devil Fruit: the Rumble-Rumble Fruit. Its electricity can make certain ship designs fly. If we happen to find it, who among you would want to eat it?"

The group fell into a brief silence. This was a legendary Devil Fruit, after all—who wouldn't want it?

Fish-Man Tom and Crocus stated they had no desire to become landlubbers, so they wouldn't consider eating a Devil Fruit. Silvers felt that if he were to eat one, it would have to be something useful for sniping.

To be honest, Redfield was very confident in his own strength and talent, and he didn't want to be saddled with the fatal weakness of fearing the sea. He hadn't considered eating a Devil Fruit either, though Brook's mention of the strongest Logia did pique his interest.

As for Shakky, she was, of course, incredibly eager; she had always longed for such a Devil Fruit!

"Haha~, we don't even know if we can find it yet, so don't fret over it now. There will be flying Mythical Zoan Devil Fruits in the future; everyone will have their chance!"

With that said, everyone was filled with anticipation for the future. Redfield secretly scolded himself for his lack of inner resolve.

Even without a Devil Fruit, he would still reach the pinnacle of this world!

"That's true, we don't even know if we can make it up to the Sky Island yet, Captain~"

Shakky pondered for a moment. Even if they confirmed the Golden City was on the Sky Island, how were they supposed to fly up there?

Brook realized he had been taking things for granted; he truly didn't have a safe method for ascending to the Sky Island. Did they really have to ride a Knock-Up Stream like Roger and Luffy?

Did they truly possess the same immense fortune that protected Roger and Luffy? One mistake could mean the destruction of their ship and the loss of their lives!

"That is indeed a serious problem we must face. The Knock-Up Stream is too dangerous, and the Float-Float Fruit user, Golden Lion Shiki, is not one of ours!"

Brook sighed, suddenly finding the situation thorny. He wondered if Moore Thomas's seagulls could fly up to the Sky Island?

In the video clips from Brook's past life, it seemed there was only one bird species on Earth capable of flying at altitudes of ten thousand meters: the Rüppell's vulture, which could reach 11,000 meters. It possessed a specific type of hemoglobin that allowed it to maintain normal flight in the thin air of high altitudes.

He wondered if the people living on the Sky Island had evolved this special hemoglobin, or perhaps the Sky Island could generate its own oxygen?

There were several other birds capable of flying above 7,000 meters, such as the whooper swan, the Himalayan vulture, the bar-headed goose, the yellow-billed chough, and the bearded vulture. The White Sea of the Sky Island was at an altitude of 7,000 meters, and the White White Sea was at 10,000 meters.

Oxygen was the primary factor limiting a bird's flight altitude; even if they struggled to reach such heights, they might perish from hypoxia. If the oxygen problem were solved, did that mean seagulls could fly to the 7,000-meter White Sea?

Would it be feasible to equip the seagulls with oxygen masks? One had to remember that the seagulls of the World Economic News Agency could pull the entire headquarters along as they flew; their flight capability and strength were immense, allowing them to deliver newspapers across the Four Blues.

Thinking of this, Brook immediately placed a call to Moore Thomas, who was already on Jaya Island, to inquire about the flight altitude and pulling power of the News Coo seagulls.

He then instructed him to prepare oxygen supplies. The production of oxygen existed in the world of One Piece; the Jaya Island salvage team and Whitebeard's medical oxygen tanks were proof of that.

With that, the problem of reaching the Sky Island had a chance of being solved.

On Jaya Island, Moore Thomas's World Economic News Agency had relocated its headquarters under the protection of his own bodyguards, avoiding the oppression of the World Government's World Peace Dove News Agency.

They were also free from the threats of the various pirates on the Sabaody Archipelago; the pirates in the pirate town on Jaya Island were much weaker. Furthermore, Brook had said he would arrive on Jaya Island soon to find the legendary Sky Island.

"Equip the seagulls with oxygen-breathing apparatus?"

He didn't understand why, but he could only follow Brook's instructions. He had already tied his family's fate to Brook.

His unique secret recipe for raising News Coo seagulls was coveted by many. Based on his family's experience, it was time to have Morgans consume a bird-type Devil Fruit, allowing him to cultivate a bond from a young age and become the new king of the News Coo seagulls.

Guided by the Eternal Pose for Jaya Island, Brook's Hell Pirates did not stop along the way, steering the Yomi directly toward their destination.
