New World, aboard the Training Ship heading to the Giant Kingdom of Elbaf.
Under Chopper's care, the injuries sustained by the trainees from their battle with Tesoro had largely healed, and they had regained their usual vitality.
At the ship's bow, Luffy was dancing animatedly in the sea breeze, loudly conspiring with Usopp and Chopper about their adventure plans.
"When we reach the Land of Giants, I must find their king and test whose fist is harder!"
"Why compete with them about fist strength?!" Usopp widened his eyes, exclaiming excitedly: "I've heard every giant warrior possesses the power to destroy an entire island! I want to learn from them to become a true warrior of the sea!"
Nearby, Chopper held a cotton candy in his mouth, his eyes full of longing.
"Are all giants huge? Would their cotton candies be as big as clouds?"
At the other end of the deck, Zoro was shirtless, his bandage-wrapped body revealing well-defined muscles.
Ignoring his injuries, he grunted through one-handed push-ups.
Brook, dressed in his proper suit, elegantly drew his bow across the violin strings.
The melodious sound of the violin flowed with the sea breeze, adding a unique artistic atmosphere to the Training Ship.
As the music ended, Brook immediately revealed his true nature, letting out a 'terrifying' laugh through his skeletal jaw.
"Yohohoho, what a vibrant movement!"
In the kitchen, the aroma of food mixed with steam wafted through the air.
Sanji hummed a tune while skillfully handling ingredients.
Beside him, Reiju gently helped wash vegetables, her pink hair swaying softly with her movements.
At the kitchen doorway, the three brothers Iji, Niji, and Yonji stood like door gods, their expressions stiff.
"Ahem," Niji cleared his throat, hands in pockets, though his gaze unconsciously drifted toward the busy pair in the kitchen.
"Hey, need any help? Our Germa technology isn't just for combat."
Without turning around, Sanji flipped his pan.
"No need. Don't get in the way here. The kitchen is a sacred battlefield."
Yonji curled his lip, muttering quietly.
"What's so great about it."
Despite their words, the three stood rooted at the doorway, awkwardly watching Sanji and Reiju, unsure how to continue the conversation.
In the training room.
Sabo looked serious, bowing respectfully to Orion who sat cross-legged in front of him.
Having unexpectedly awakened Conqueror's Haki during the battle with Tesoro, he was so excited that he sought Orion's guidance before his injuries had fully healed.
"Fleet Admiral, I have many questions about Conqueror's Haki. I'd appreciate your guidance."
Orion nodded: "Go ahead."
On the other side of the training room, Ace stood by the window as a faint black arcs of electricity occasionally flashing around his right fist.
He was fully focused on trying to integrate his newly mastered power with his flames.
As soon as Sabo finished questioning, Ace quickly approached Orion, his eyes burning with intensity.
"Fleet Admiral, can I wrap Conqueror's Haki around my flames to elevate their power to an entirely new level?"
Orion smiled and nodded.
"Of course. Though it's very difficult at your current level, you're heading in the right direction."
As he spoke, he casually picked up a smooth pebble from a nearby potted plant.
An invisible surge of Haki emanated from his fingertip, silently coating the stone.
The ordinary pebble's surface seemed to be plated with an invisible film.
Orion flicked his finger.
The pebble became a blur, shooting out through the open window and silently cutting across the sky.
Ace and Sabo instinctively followed the stone's trajectory with their eyes.
Just as the two turned their heads, the sea surface a hundred meters away abruptly exploded without warning!
"BOOM—"
Amid the deafening blast, a towering water column shot skyward as if triggered by a depth charge, while the expanding shockwave whipped up massive waves several meters high.
Ace and Sabo's eyes nearly popped out of their sockets.
Their jaws dropped simultaneously as they exclaimed in unison, "Conqueror's Haki can be used like this?"
"These are just basic applications," Orion said calmly. "Once you fully master Conqueror's Haki infusion, you'll discover its uses extend far beyond this."
"For example, you can pre-infuse Conqueror's Haki into containers, even a piece of paper or a wall, and set activation conditions. Any unlucky soul who touches the paper or wall storing Conqueror's Haki will instantly be suppressed by the released energy."
Just as Orion finished speaking, Gunko in the Flower Room of the Holy Land sneezed for no apparent reason.
At that moment, Morgan quickly entered the training room, standing at attention and saluting before Orion.
"Report, Fleet Admiral! The training ship is about to arrive at Elbaf!"
Before Orion could respond, Luffy and Usopp's excited, cracking shouts could already be heard from outside the training room.
"Wooohooo! Giant Kingdom! A new adventure begins!"
"Wow! I'm finally going to meet the legendary Giant Warriors!"
...
Meanwhile.
In the New World, at the Giant Kingdom of Elbaf.
Towering fern plants stood like skyscrapers, while massive weapons and shields leaned casually against mountain walls as if belonging to a divine armory.
At the island's center, a colossal tree named 'Adam' pierced through the clouds, majestic and magnificent.
From the Walrus Academy at the Warrior's Spring in The Sunny World came the sound of childish reading voices.
The tall biology teacher Ripley, with her distinctive twin-tails hairstyle, patiently explained the habits of various magical creatures to a group of Giant children.
Outside the academy, on an inconspicuous patch of grass.
A man wearing sunglasses and sporting signature handlebar mustache lay sprawled out, leisurely enjoying the sunlight.
This was none other than the former crew member of the Roger Pirates, renowned alongside Rayleigh - "Copper" -
Scopper Gaban!
The Grand Line's greatest mountain eater!
Suddenly, Gaban's ears twitched unconsciously.
The next moment, he flipped over and sat up, all laziness vanishing from his face, replaced by unprecedented seriousness.
Because just then, his Observation Haki had been passively triggered, capturing a clear vision from the future.
In the vision, a Marine Training Ship was approaching Elbaf.
Alongside it, another warship that had somehow entered Elbaf's waters was converging with it just before reaching the island.
Standing on the warship's deck were none other than the World's Greatest Swordsman, Dracule Mihawk, the Devil Child Nico Robin, the Ghost Princess Perona, Kaido's daughter Yamato, and Nekomamushi from Zou, among others.
Having captured this vision, Gaban didn't hesitate for a second, his figure flashing as he disappeared from the spot.
When he reappeared, he was already perched in a tree at the edge of the cliff near West Village in The Sunny World.
Though he couldn't visually spot the Training Ship and warship on the horizon through the leaves, he was certain his Observation Haki couldn't be wrong.
"Fleet Admiral Orion?"
"Why would he suddenly come to Elbaf!"
