Rumble Fruit

An hour later, Kahn walked out of the auction room, slightly disappointed. His expression made it clear that the Celestial Dragons hadn't bought the three Boa sisters or the Paramecia Love-Love Fruit at this auction.

The Love-Love Fruit might not have been available in the auction, perhaps given to the Celestial Dragons by someone else or won by them in a bet with other Celestial Dragons. Kahn felt a bit regretful about not obtaining the Love-Love Fruit.

However, Kahn quickly calmed down after leaving the auction house. Even if he had managed to get the Love-Love Fruit, he likely wouldn't have given it to Hancock. While Hancock has high compatibility with the fruit, which, combined with her charm, petrification abilities, and Conqueror's Haki, would make her a formidable pirate, second only to Charlotte Linlin, Kahn had different plans for her.

Kahn aspired to train Hancock to be as strong as Silver Rayleigh, Benn Beckman, or Roronoa Zoro—one of the strongest lieutenants, nearly as powerful as the captain or just slightly weaker. If he found the Devil Fruit, he'd keep the Love-Love Fruit to train a regular crew member later. If he couldn't find it, he'd give it to Hancock, letting her growth path mirror the original story.

But now, with the hope of getting the Love-Love Fruit almost gone, Kahn had only one choice left.

Returning to the hotel, Kahn spoke to Robin, who was teaching the three Boa sisters maid etiquette and giving them lessons on sea-related common sense. "Clean up; we should leave here."

"Yes, Master," Robin replied without questioning, and she started packing with the puzzled Boa sisters.

Soon, Kahn left the hotel with the four girls in maid outfits, drawing envious looks from passers-by. When they were alone, Kahn used his telekinetic power to lift the girls into the air, flying them to a height of 7,000 meters. Ten minutes later, they passed through the sea of clouds and returned to the Blue Sea.

Using wind control to accelerate the sailboat, Kahn navigated back to Water 7. He didn't stay long but headed straight for Long Ring Long Land, the next stop after Water 7.

However, between Long Ring Long Land and their destination, Skypia Island was another island: the legendary Sky Island, the other half of Jaya Island, now known as the Island of the Gods.

Kahn's next destination was Skypiea, specifically Birka, another island in the Skypiea region.

Kahn had set his sights on the Logia Rumble-Rumble Fruit, considered the strongest among Logia fruits, for Hancock. He believed that a powerful Devil Fruit in the hands of a strong individual like Hancock would make her a monster in terms of strength.

If Hancock consumed the Rumble-Rumble Fruit, her template would resemble Kizaru but with Conqueror's Haki. Kahn envisioned her as an Admiral-level player, and once she mastered the advanced use of Conqueror's Haki, she would become a superpower on par with the Pirate Emperors.

Kahn had high hopes for Hancock, aiming for her to become a legendary figure akin to the Pirate King's right-hand person.

There was a saying in his previous life: no one can single out two Admirals. This means that no matter how powerful you are, you cannot defeat a combination of two Admirals. Similarly, no one can single out two Pirate Emperors.

Before Kahn arrived, even Luffy could only defeat Kaido in a one-on-one fight by constantly disconnecting. Kaido also endured multiple battles and supported an island throughout the process.

When there are two Emperors in a pirate crew, every move they make alarms all forces. The original Red Hair Pirates were such a crew. Because of this, wherever Shanks went, everyone, including Kaido, would show him respect. 

But if Kaido decided not to give respect, Shanks and Benn Beckman would take him on. Similarly, if Hancock became an Emperor, Kahn could take her out, and aside from the World Government and Marine Headquarters, other forces would show him respect. At that time, Kahn would also gain face. 

Therefore, Kahn is determined to get the Rumble Fruit.

...

Once the Log Pose is fully charged with magnetic force, it can guide you forward or backwards. For example, if the magnetic force is fully stored on an island, whether moving forward or backwards, the Log Pose will be attracted to the nearest island's magnetic force.

With the Log Pose fully charged in Water 7, Kahn sailed his Ship to Long Ring Long Land in less than two days. Long Ring Long Land is a very unique island, shaped like a long ring and usually divided into ten smaller islands by the sea, resembling an archipelago. However, these ten smaller islands are actually one.

Every year, when Water 7 experiences the Aqua Laguna, Long Ring Long Land also experiences a great ebb tide, turning the ten smaller islands into one. The nomads on the island seize this opportunity to move to the next island.

The animals on Long Ring Long Land are also distinctive, being quite elongated, and the island residents speak in elongated tones, which can be irritating to outsiders. 

For Robin, it was her first time on such an island, excluding Water 7 and the Sabaody Archipelago, and she was extremely surprised. The three Boa sisters also marvelled at the wonders of the outside world.

Kahn's group spent three days on Long Ring Long Land. Once the Log Pose was fully charged, they moved on. After another two days, the Log Pose's needle pointed straight up like it was malfunctioning. 

Seeing this, Robin, who had been watching and training the three Boa sisters, gradually got involved. The three Boa sisters, who now respected Kahn deeply, immediately used their powers to support the Ship, soaring into the sky.
