Arthur submerged himself in the White-White Sea, using the water pressure to train his strength. Day and night, he opped training.

  Even though his current strength was vastly different from before, he didn't sck off.

  In the world of One Piece, relying solely on Devil Fruit's powers was not enough. A powerful physique araordinary stamina were o use a Devil Fruit's powers tinuously.

  Most fruits required physical strength to be used to their full potential.

  Moreover, the strohe body, the faster a Devil Fruit's powers would develop.

  When a fruit was eaten, it took effect immediately. But those with stronger bodies developed their powers faster than those with weaker bodies.

  Luffy could stretch his body immediately after eating the Gomu-Gomu Fruit. But he couldn't trol it well. He would often hit himself by act. But when Sabo ate the Fme-Fme Fruit, he could use fire attacks right away. This roof.

  Therefore, physical fitness determihe use of most Devil Fruit powers.

  "Spsh—"

  Arthur climbed out of the sea, shaking the water off his body. He casually put on clothes he had taken from a vilger and began his breakfast.

  After searg all of Birka for a whole year, finding nothing, Arthur realized that maybe the Rumble-Rumble Fruit wasn't on Birka at all.

  ...

  After eating breakfast, Arthur began to recall his memories about Enel's life.

  Enel destroyed Birka. Then he led his men to attack Upper Yard. He drove out the God, Gan Fall. He took od's Land and became the new God. He then began to use the God Squad to build the Ark Maxim. This was in the year 1514.

  The blueprints for the Ark Maxim were, needless to say, taken from Birka. But before he destroyed Birka, he must have already obtaihe power of lightning, which he called "God." How did he get the Rumble-Rumble Fruit?

  Or rather, Enel had nth to speak of. His Observation Haki was immature. His physical skills were notoriously poor. The vilgers of Birka could have easily beaten him. How could he destroy Birka?

  From this, it could be deduced that before he destroyed Birka and attacked Upper Yard, he must have already obtaihe Rumble-Rumble Fruit.

  Sihat was the case, the Rumble-Rumble Fruit was definitely not on Angel Isnd or Upper Yard. It had to be near Birka.

  However, Arthur had searched every er of Birka and found nothing.

  Therefore, it could be inferred that Enel had obtaihe Rumble-Rumble Fruit from elsewhere, or from the White-White Sea.

  Thinking of this, Arthur's furrowed brow rexed. This was indeed a possibility.

  Devil Fruits were the treasures of the sea. They appeared randomly in some er of the o.

  Acc to this, did that mean that Sky Isnd didn't produce Devil Fruits? Were they brought up by the rising current or by people who entered Sky Isnd?

  It made sense. Looking at the whole of Sky Isnd, besides Enel's Rumble-Rumble Fruit, there was only the current God Gan Fall's mount, that pink-winged bird that had eaten a Devil Fruit. The Zoan-type Horse-Horse Fruit, Pegasus Form.

  Sky Isnd could not produce Devil Fruits. So far, only these two examples had appeared. Then the probability that the fruit was brought up by the rising current from the Blue Sea was very high.

  Having sorted out his thoughts, Arthur's heart pounded. Even taking deep breaths couldn't calm him dowhought this was very likely.

  But although Birka was small, the area of the White-White Sea was huge. It wasn't something Arthur could sear a short time.

  ...

  "Enel was often bullied by the vilgers. He couldn't stand it. One day iure, he might build a boat and leave Birka. Although the vilge cut off tact with Angel Isnd, everyone knows the dire of Angel Isnd. In that case, the Rumble-Rumble Fruit must be between Angel Isnd and Birka!"

  Arthur's mind began to clear. His analysis sped up.

  "That's not certain! Another possibility is that the blueprints for the Ark Maxim were avaible for anyone on the isnd to see, except for Enel. He must have secretly goo look at them because he wao go to his dreamnd—the moon, the Endless Vearth."

  "This vioted Birka's ws. The vilgers had long wao execute Enel but didn't have an excuse. This act of secretly looking at the blueprints for the Ark was their excuse to kill him!"

  "The method of execution on Sky Isnd is called Cloud Drifting. They put Enel on a drift cloud a him float around, to fend for himself. By luck, he obtaihe Rumble-Rumble Fruit!"

  He thought it over. These were the only two possibilities. Arthur didn't believe that Enel found it iers near Birka.

  Because he had already searched the nearby waters. He hadn't found any fruit. There weren't even any shipwrecks. Not even the nearby marine life had escaped Arthur's belly. They had long been digested into nothing.

  "First, I'll ask around the vilge. I'll find out where they carry out the Cloud Drifting executions. Then I'll sear that dire. If that doesn't work, I'll sear the dire of Angel Isnd."

  ...

  Having made his decision, Arthur didn't want to dey any longer. He was eager to eat the Rumble-Rumble Fruit.

  Dressed ly, Arthur rushed towards the vilge. Before long, he entered a vilger carrying a fishi, about to go fishing.

  He stopped. He put his long hair behind his head. He gave what he thought was a kind smile. He asked.

  "Excuse me—where on Birka do they carry out the Cloud Drifting executions? I'm curious—"

  But the vilger ignored Arthur. He walked right past him. He muttered to himself.

  "A wingless freak, asking about Cloud Drifting? Does he want to try it? What an idiot."

  Arthur's Observation Haki was now quite advanced. His five senses were extremely sharp. How could he not hear this muttering? His smile froze on his face. A cold glint fshed in his eyes.

  "It seems, only by showing strength, by beating them until they're scared, will they choose to unicate normally. In that case—"

  He turned around. He suddenly reached out. He grabbed the back of the fisherman's neck. He lifted the old man, who weighed less than a hundred pounds, off the ground.

  "If you don't want to talk, I have plenty of ways to make you talk!"

  Arthur grinned coldly. He couldn't stand this disrespectful old man any longer. He carried him and strode back towards the beach.

  "What do you want to do? You freak, do you want to kill someone? I'm going to report you to the vilge chief. You'll be senteo Cloud Drifting. Freak, let go of me—Ah!"

  "Pa!"

  "Shut up. If you keep talking, I'll make yret it!"

  "Pa!!"

  "Pa!!!"

  Arthur spped him. The fisherman quieted down. He looked at Arthur's cold, emotionless eyes. He looked at him fearfully.

  Ba the beach, he casually tossed the old man onto the isnd cloud. He said coldly.

  "Tell me—where do you carry out the Cloud Drifting executions on this isnd!"
