The Evil Pirates of the Sixth Underground Level!

On the way to Impel Down.

Roya felt the changes in himself after several days of training.

With his own efforts and the boost from automatic training, the Dark-Dark Fruit power he had mastered had now reached the intermediate level.

The time required to train an ability from beginner to intermediate was relatively the shortest.

"System, show me the training programs I've established!" Roya asked.

[Host: Roya]

[Marine Six Powers (Ability Strength): Top-tier (Twentyfold Automatic Training in Progress)]

[Observation Haki (Ability Strength): Advanced (Twelvefold Automatic Training in Progress)]

[Armament Haki (Ability Strength): Advanced (Twelvefold Automatic Training in Progress)]

[Swordsmanship Power (Ability Strength): Swordmaster Level (Automatic Training in Progress)]

[Conqueror's Haki (Ability Strength): Upper Level (Automatic Training in Progress)]

[Dark-Dark Fruit Power (Ability Strength): Intermediate (Automatic Training in Progress)]

Looking over the training programs he had established once more, Roya was clearly much calmer now.

Mm, it's still not enough. I need to become even stronger! Roya silently resolved.

Just then, a marine soldier came to report, "Rear Admiral Roya, we've passed through the Gates of Justice. We're about to reach Impel Down!"

Roya's status had soared after his battle against Blackbeard and his crew, and the marine soldiers following him admired him deeply.

Even the report was delivered in a tone full of respect.

"Alright, I understand," Roya replied.

Walking out of the cabin and standing on the deck, he looked into the distance and saw the magnificent structure of Impel Down.

At the same time.

Outside Impel Down's gates, Magellan, the warden, personally waited there with a large number of prison guards.

After all, Fire Fist Ace was about to be imprisoned. Marine Headquarters had already made arrangements with Magellan, and absolutely no mistakes could be allowed. Based on Fire Fist Ace's danger and threat level, Marine Headquarters had ordered that he be locked in Infinite Hell on the sixth underground level of Impel Down.

The prisoners held in Infinite Hell on the sixth underground level were all utterly vicious pirates.

As the warship docked, Magellan came forward to receive them.

"Rear Admiral Roya, I already know why you've come. Leave the prisoner, 'Fire Fist' Ace, to our people," Magellan said coldly.

The guards beside Magellan had also prepared new Seastone shackles.

"Fine." Roya nodded, then motioned for the marine soldiers behind him to escort Fire Fist Ace down.

With Roya and Magellan personally present, the entire handover proceeded without the slightest mishap.

Very soon, the guards escorted Ace toward Impel Down.

"Alright, Rear Admiral Roya. Leave this prisoner to Impel Down. You may return now," Magellan said with a wave of his hand.

"Wait, Warden Magellan. By Fleet Admiral Sengoku's orders, I need to go in with you and personally confirm that Fire Fist Ace has been imprisoned before I can return and report to them," Roya said.

"Rest assured, Impel Down is an impregnable fortress. Once a criminal enters, there's no possibility of escape."

Magellan spoke with complete confidence, but he still nodded. "However, since Fleet Admiral Sengoku has requested it, Rear Admiral Roya, come along."

When Roya heard Magellan say that no criminal had ever escaped, he had nearly wanted to make a sarcastic remark about the "Golden Lion," Shiki.

But aside from that legendary great pirate, no prisoner in Impel Down's history had ever successfully escaped.

The next moment, Roya followed Magellan and the others into Impel Down, while the warship remained temporarily docked at Impel Down's simple harbor.

Along the way, Magellan was fairly accommodating, introducing Roya to the layout of each level of Impel Down. However, his tone was somewhat cold, giving off the feeling that he kept everyone at arm's length.

After entering Impel Down, the first level was the sea-level floor, where prisoners arrived after entering the gates. No prisoners were held on this floor. Beyond the entrance was an iron gate, and behind it lay the place where criminals underwent "baptism" and interrogation before imprisonment.

They then passed through Crimson Hell on the first underground level, Wild Beast Hell on the second underground level, Starvation Hell on the third underground level, and Blazing Hell on the fourth underground level.

The first two levels held prisoners whose crimes were less severe and whose strength was fairly ordinary, so Roya was not particularly interested as Magellan explained them.

As for the third and fourth underground levels, they were somewhat better, especially Blazing Hell on the fourth level, but they still held no interest for Roya.

Furthermore.

On every corresponding level of hell, these prisoners had already been tortured until they wished they were dead. When they saw Magellan, they did not dare utter a word.

Not until they reached Freezing Hell on the fifth underground level.

The prisoners here were all wanted pirates with bounties exceeding one hundred million, figures who could at least be considered minor players in the world of One Piece.

Finally.

They smoothly arrived at the sixth underground level, Infinite Hell!

Those sent into Infinite Hell on this level were no ordinary people. They were either death-row prisoners or sentenced to life imprisonment. The criminals imprisoned here were monstrous pirates so vicious that they had been erased from history. The inmates on this level were nearly legendary figures, and their fates were either execution or lifelong imprisonment. Because these prisoners had committed countless atrocities and carried out acts too cruel to reveal, the government had covered them up, even deliberately concealing them from the newspapers.

And after arriving on this level.

Even upon seeing Magellan, these prisoners were not as wary as those on the previous levels. Instead, they continued to mock him.

However, many of them cried out in surprise when they saw Fire Fist Ace.

"The criminals on this level are all heinous. Especially those held in solitary confinement—back then, they caused massive upheavals. Some even had every trace of their existence erased!" Magellan said in a deep voice, raising his hand to point at the cells as he introduced them one by one.

"The cell at the end of the corridor holds Douglas Bullet, known as the 'Son of the Demon'! He once nearly caused your Marines' Buster Call operation to fail!"

"The solitary cell on the right holds Redfield, the 'Red Count,' a powerhouse from the same era as your Marine hero Garp! Back then, his fearsome reputation rivaled Whitebeard and Golden Lion!"

"The enormous cell at the very back holds only one person—Sanjuan Wolf, the 'Giant Battleship'!"

"..."

These infamous great pirates were now known by very few people outside.

Hancock, the "Pirate Empress," who had entered Impel Down alongside Roya, had heard of these people. Her icy expression gradually changed, and a trace of shock appeared in her beautiful eyes.

Just as the rumors said, the prisoners held in Infinite Hell on the sixth underground level of Impel Down are all monsters! she thought in shock.

Beside her, Roya naturally knew the names of these great pirates as a transmigrator.

But these guys had all become prisoners. What was there to fear?

Still, considering how vicious these great pirates were, it was no wonder they did not fear Magellan at all and even dared to challenge him.

"Hey! Magellan, what brings you to this level today?"

"Oh! You even brought a pretty little girl!"

"Huh? Isn't that Fire Fist Ace, the commander of the Whitebeard Pirates' Second Division?"

"How did he get captured too?"

"Hahahaha! This is great! They actually dared to capture someone from the Whitebeard Pirates, and even the commander of the Second Division. Whitebeard definitely won't let these Marines off!"

"Maybe if Whitebeard tears Impel Down apart, we'll get a chance to escape with him too, brothers!"

The utterly vicious criminals on this level spoke without restraint and burst into laughter.

However, Magellan had long grown accustomed to it and paid them no attention. Instead, he turned to Roya and said, "Rear Admiral Roya, we've arrived. This is Infinite Hell. Sengoku said Ace is to be imprisoned here."

Hearing this, the prisoners all shifted their gazes toward Roya.

"Why is there a Marine rear admiral tagging along? What, did he subdue Fire Fist Ace?"

"What are you thinking? That's Fire Fist Ace. Without strength, could he have become a commander of the Whitebeard Pirates?"

"Exactly. This rear admiral is probably just some errand-running lackey. What can a rear admiral do? Do you think he's that strong?"

The prisoners began directing their mockery at Roya.

"These people are too noisy." Roya frowned and looked around at the prisoners.

Suddenly.

Roya made his move. With a fierce glare, he unleashed his Conqueror's Haki.
