If Enel could awaken Observation Haki at such a young age, without training, his talent was incredible. With some guidance, he would be a top-tier talent.

  But Arthur's memories of the Skypiea arc were hazy. It had been too long since he had watched the anime. He vaguely remembered that there was a "Mantra" trainihod on Sky Isnd. It seemed like Enel himself had mentio.

  If Birka really had a method for training Observation Haki, Arthur wouldn't mind taking it first. After all, he had awake a few days ago, but he didn't know how to use or improve it. Having a specific dire was better than fumbling around in the dark.

  Perhaps because he had found a "kindred spirit," also without wings, Enel was much more talkative. He said excitedly, "I could have fought them. I used to win hts. But after I beat them, they would tell their parents, and then..."

  He looked indignant. Arthur realized that Enel was just a naive child right now. He wasn't the ruthless tyrant who would destroy aire isnd without a sed thought.

  't you just call for backup if you 't win? Where was the fairness in that? Relying on your parents was a skill too.

  Arthur uood this logi his past life.

  Enel didn't know what he was thinking. He tinued, "I learhis ability from a book my parents left me. It's called Mantra, I've been practig it since I was little. Big brother, if you want, I teach you!"

  He looked at Arthur with hopeful eyes. He wao show off to his "kindred spirit," to be aowledged.

  Arthur looked at Enel's i eyes. He suddenly felt a little evil, a twinge of guilt. He had just been thinking about stealing the Observation Haki trainihod and then killing Enel after taking the Rumble-Rumble Fruit.

  'Once I steal your Rumble-Rumble Fruit, I'll find you a det fruit to pensate,' he thought to himself.

  "No worries, I'll e to your pce ter to take a look. I hope you won't hide it from me then." Arthur pushed away the guilt. He patted Enel's fluffy head.

  "Really? That's great..." Enel shouted excitedly. He couldn't tain his joy.

  He had never been this happy before.

  "Cough cough!" Arthur sidered himself a vilin, a ruthless killer. But even he couldn't stand a child's i gaze. He had to ge the subject. "By the way, since your parents left you something, where are they?"

  "On the Endless Vearth." Enel's chatterbox en. He was cirg around Arthur, answering every question. "I will definitely go to the Endless Vearth and find them one day."

  Endless Vearth was the moon. Skypieans longed for nd. They believed the Endless Vearth was their best destination.

  'Poor kid,' Arthur thought. He pitied Enel's parents for three seds.

  Most of his questions had been answered. The kids who had beaten Enel said he had stolen the "ship" blueprints. It robably because Enel wao build the "Ark Maxim," himself, to fly to the Endless Vearth.

  "Well, good luck!"

  "Yeah!"

  ...

  They chatted for a while. Arthur made up an excuse and parted ways with Enel. After all, he was busy. He o find the Rumble-Rumble Fruit, his dream.

  But before that, maybe he should get his hands on the Observation Haki trainihod? And steal the blueprints for "Maxim" hidden in the vilge?

  Of course, Arthur had no i in the so-called Endless Vearth, He wahe Maxim because that ship ractically tailor-made for the Rumble-Rumble Fruit's user.

  A pirate ship powered by electricity was a huimes more advahan one powered by wind!

  Arthur was incredibly excited about it. Just imagine, iure, he would pilot this golden ship across the Red Line. He would fire a shot at Mary Geoise from the sky. How awesome would that be?

  The Celestial Dragons could only stare. They couldn't do anything to him. Or maybe someoh aerial abilities could try to surround him? Would the Rumble-Rumble Fruit fear aerial bat?

  Upper Yard had endless gold. It was the perfect material for building the Maxim.

  When the blueprints and materials were all gathered. With the addition of Sky Isnd's various and magical Dials, this ship would surpass the "Thousand Sunny," the "Oro Ja," and the "Moby Dick" the moment it was born!

  Thinking about this, he was itg to get started. He wao make this divine ship a reality.

  ...

  He followed Enel all the way. Without alerting him, Arthur entered Enel's dipidated and cramped home. He searched around. He quickly found the "Mantra" trainihod.

  The trainihod for Observation Haki was actually very simple. Arthur had already awake, so he skipped the beginning and flipped to the back.

  He found a er and started reading. The more he read, the more shocked he became.

  Arthur was certain. The person who left this trainihod must have been a strong user of Observation Haki.

  The book said that as long as a creature was alive, it would emit a unique sound. It could be heard. Not only that, even inanimate objects had sounds. But hearing the sounds of inanimate objects was extremely difficult.

  Wasn't this just like Gol D. Roger's ability to hear the Voice of All Things?

  He excitedly tinued reading. By the end, even a person's thoughts, their life force, predig death, and glimpses of the future were all mentioned in the book.

  This was a prehensive encyclopedia of all Observation Haki development paths.

  "Unbelievable!" Arthur almost ughed out loud. This book was invaluable to him. He hadn't expected such a gain from ing to Sky Isnd. Even if he couldn't find the Rumble-Rumble Fruit, it would be worth it.

  He had awakened Observation Haki innately. It was much strohan those who trained for it. He could try to train in all the highest levels and development paths of Observation Haki.

  If he succeeded, with the amplification of the Rumble-Rumble Fruit, who on the Grand Line could say their Observation Haki was strohan his? Roger, Fujitora, Otohime?

  He put the book ba its pce. He made sure it looked untouched. Arthur searched the dark room. He hid a Light Dial in his clothes. He carefully looked for any sign of the Rumble-Rumble Fruit.

  Enel's parents had left him the "Mantra" trainihod. Maybe they had also left him the Rumble-Rumble Fruit. Arthur wouldn't give up any possibility.

  Meanwhile, Enel was outside, preparing food. Arthur quickly searched.
