His instincts couldn't be wrong.
A monster like this could never be defeated easily.
Yet Roy grew even more excited as Shiryu attacked again.
"Continuously gathering and compressing the body's strength, wrapping a layer of black energy around the arms and weapons..."
"So this is Armament Haki. How interesting!"
He laughed loudly and flicked his fingers.
An ordinary slash shot out, colliding head-on with Shiryu's swordsman's slash.
Bang! Bang!
Energy exploded with a loud blast.
Roy's ordinary slash easily shattered Shiryu's attack, and its residual force even continued toward Shiryu.
"Hiss... you're a master swordsman?"
"No! You unleashed a slash without a sword. You've got to be kidding!"
Shiryu was utterly shocked to see his master swordsman's strike so easily crushed.
But in the blink of an eye, the slash was already before him.
Fortunately, his Observation Haki detected the danger, allowing him to barely dodge at the last instant.
Drip!
Shiryu reached toward his waist and abdomen, where a five-centimeter wound had appeared.
For the first time, genuine fear showed in his eyes.
"How is this possible... I clearly used Observation Haki, yet I still got hurt at the last moment?"
"And with damage this terrifying, if I hadn't dodged, the consequences..."
He no longer dared to think further.
With just one attack, Roy had fully revealed his terrifying might.
Even using Observation Haki hadn't prevented injury. This monster was on an entirely different level.
Criminals and jailers elsewhere on the battlefield also noticed the scene.
The jailers fell into complete despair.
"Damn it! Can't even Chief Warden Shiryu beat that Roy? That's impossible!"
The crazed criminals had already been giving them enough trouble.
Now Shiryu, their chief warden, had fallen into an absolute disadvantage as soon as he appeared.
Under these circumstances, could they really hold out until reinforcements arrived?
But there was no time to think about it now. They could only grit their teeth and continue fighting the increasingly frenzied criminals.
After all, the criminals had also witnessed Roy's strength, and their longing for freedom had grown even stronger.
Roy remained utterly calm through it all.
He carefully studied how Shiryu had just used Observation Haki and Armament Haki.
"Hahaha, so this is Observation Haki?"
"Focusing the mind intensely, sensing everything around you, locating things by sound, anticipating danger."
"You're so interesting, Shiryu. I hope you can entertain me to your heart's content."
With that, Roy walked unhurriedly toward Shiryu, carrying an oppressive presence.
He had decided that he couldn't let Shiryu die so easily.
He still needed him to practice Observation Haki and Armament Haki.
Although he possessed Admiral-level strength, he had yet to master Haki.
Against an expert of the same level, he would inevitably find himself at a disadvantage.
And Ryomen Sukuna happened to possess one-in-ten-thousand abilities to learn, adapt, and analyze.
Once he finished learning Observation Haki and Armament Haki from Shiryu, there would still be time to send him to hell.
Shiryu's breathing had now grown rapid.
"Heh, you really are an interesting monster. I've never been looked down on like this before. Even Magellan has to show me some respect."
He was a madman to begin with.
The closer danger came, the less he would back down.
"I hope your blood can truly excite me!"
"One Sword Style: Thousand Needles!"
In an instant, brilliant sword light shone from Raiu's blade, unleashing hundreds upon thousands of needle-thin sword-energy attacks that rained down.
Wherever the sword energy passed, densely packed holes instantly appeared in the ground.
The expressions of both sides in the melee changed drastically, and they hurriedly retreated.
If a sword technique like that struck them, they would undoubtedly die.
Yet Roy remained calm before the sword needles raining down from the sky.
He merely raised a hand casually, and slashes wiped them all out.
"Soon, soon. It won't be long before I've finished analyzing them."
Even in battle, he continued analyzing Observation Haki and Armament Haki.
Everyone fell silent.
How were they supposed to fight a monster who ignored attacks like this and kept advancing step by step?
Perhaps they should simply surrender.
Shiryu, however, had not despaired.
He tightened his grip on Raiu and charged straight at Roy.
"Keep fighting, you monster! I refuse to believe you really can't be hurt!"
"One Sword Style: Thunder Flash!"
He unleashed an exceptionally fierce sword technique.
Yet Roy merely glanced at the lightning-like strike and easily dodged it.
"Heh, still not quite enough. Keep attacking."
Roy even had the capacity to offer commentary, casually landing a punch on Shiryu.
The immense pressure made Shiryu suffer terribly.
"Argh! You monster, you're really pissing me off!"
He could only activate his Observation Haki to dodge rapidly.
Yet what drove him to even greater despair was that he seemed to evade every attack Roy made.
But with each subsequent attack, evasion felt increasingly difficult.
This forced him to burn his bridges, grit his teeth, and take the damage head-on as he clashed with Roy.
But doing so played right into Roy's hands.
The two continued clashing like this.
Everyone present could see it clearly, and they even felt sorry for Shiryu, who had made such an imposing entrance.
Roy was simply using him as a stepping stone, constantly honing something.
Shiryu was going to lose.
Meanwhile, amid the great battle, Domino and the others were also rushing over to provide support.
They, too, saw Shiryu, who should never have been getting beaten back, now completely suppressed by Roy, and every one of them grew terrified.
"How is this possible? Chief Warden Shiryu may be a ruthless killer, but he's still the true number two in Impel Down!"
"Even Chief Warden Magellan is wary of him. Why is he getting beaten back now?"
When they heard that a powerful fighter like Chief Warden Shiryu had arrived, they had intended to come help suppress the uprising.
Instead, they were greeted by the sight of Shiryu being overwhelmed.
How could they not be afraid?
"Hold on! Once Chief Warden Magellan arrives, no matter how strong that Roy is, he can't possibly fend off both of them at once!
Let's clear out the criminals here first. Then Roy won't have any helpers!"
Domino lived up to her position as vice warden. Despite her terror, she quickly made a judgment and led the jailers into battle against the criminals.
With their arrival, along with the powerful beasts coming down from above, the first-floor criminals, already the weakest, immediately felt tremendous pressure.
They had long been underfed and physically weak, and their weapons were no match for those of the burly jailers.
Hot blood alone could only take them so far.
Soon, more than half of this force of nearly a thousand had been subdued, and their numbers continued to dwindle.
At this rate, the first-floor criminals would soon be completely defeated.
This so-called prison break was also destined to struggle to succeed.
However, aside from throwing all of Impel Down into an uproar, the first-floor prison break had yet to cause any other substantial effects.
Meanwhile, at Marine Headquarters, Marineford, which lay at the very heart of the triangular defensive line formed with Impel Down and was closely connected to it, intelligence personnel likewise detected the unusual loss of signals from Impel Down.
Inside the Intelligence Room, the Den Den Mushi's signal light flickered before falling completely silent.
The intelligence personnel responsible for monitoring communications with Impel Down abruptly paled.
"What's going on? Another signal from Impel Down has cut out!"
"That's already the sixth channel! Crimson Hell on the first floor, Infinite Hell on the sixth, Blazing Hell on the fourth... we've lost contact with all of them!"
"Quick, report to the Fleet Admiral's Office immediately! Something serious may have happened at Impel Down!"
Several intelligence officers frantically began trying to reconnect the signals.
But no matter how they called, all that came from the other end was lifeless static.
Everyone's expression grew increasingly grim.
"Impel Down is the underwater prison the World Government relies on most. How could so many communication channels suddenly go down?"
"There's only one possibility: deliberate sabotage. And multiple communication nodes were destroyed simultaneously."
"Damn it, what on earth happened there?"
The Intelligence Room fell solemn, its oppressive atmosphere weighing like lead on everyone's hearts.
Before long, an urgent report was delivered to the office area of the Navy High Command.
