Recruit Luffy at the start and build the strongest navy.

A large hole was torn in the stone fence in the middle of the cell, and occasionally purple lightning flashed across it.

The entire cell had turned from its original gray stone color to black. Inside the cell, a charred body lay, with wisps of black smoke rising from its body.

"hiss!!"

Gasps of shock echoed around them.

Wang Zhi... just lay down like that?

The prisoners here are almost all skilled in Observation Haki, so they can naturally sense Wang Zhi's current state.

Although he wasn't dead, his breath had become extremely weak.

no?!

Wang Zhi was already considered a top expert among these prisoners, with his strength firmly in the top five among all the prisoners.

And now...

???

The next moment, everyone simultaneously shifted their gaze from Wang Zhi and looked at Kyle.

The same thought popped into their minds simultaneously.

"When did the Navy produce such a formidable figure?!"

Not only were the prisoners surprised, but Magellan behind Kyle was equally astonished.

He had expected Kyle to be strong, but he didn't expect him to be this strong!

As expected of the man who could defeat Kaido, with the strength to kill Wang Zhi in one blow, even a few more Kaidos wouldn't be enough to defeat him!

Of course, these are just people's wild guesses; Kyle's strength is definitely not that great.

He himself knew this.

The reason it can achieve this effect is mainly because the entire structure is made of steel bars, and the fence is made of a mixture of sea stone and metal.

After Kyle's thunderous outburst, a terrifying electric field formed throughout the cell, causing the lightning inside to become extremely violent and constantly bombard Wang Zhi.

So it might seem like Kyle only landed one hit, but the actual effect was far stronger.

Moreover, Wang Zhi himself was bound with sea stone, so he didn't have much ability to resist.

A combination of factors allowed Kyle to deliver such a powerful blow.

Otherwise, if Kyle could defeat Wang Zhi in one blow, his strength would probably reach the level of the former sea tyrant, Rocks.

However, the gap isn't too large now.

The day when a single blow can defeat an ordinary general is not far off!

"Commander Magellan, is it alright to have the cells like this?"

Kyle suddenly turned to Magellan and asked.

"It's alright, there are plenty of cells on the six underground floors. Damaging just one won't cause any problems!"

"Alright! Then I'll trouble Director Magellan to make the arrangements!"

After saying that, Kyle looked around and released his Observation Haki, finding his target almost instantly.

They slowly made their way towards a certain prison cell, and soon stopped in front of one of the cells.

Like the other cells, this cell was very dark, damp, and cold.

In the darkness of the cell, a vague outline could be faintly seen.

Kyle's gaze was indifferent, then he suddenly spoke:

"Douglas Barrett!"

"I've long admired your name!"

Upon hearing these words, the person inside slowly stood up and emerged from the darkness, their overall outline gradually becoming fully visible.

Tall and strong, with blond hair, a body covered in scars, and... devilish eyes.

The legendary heir of the devil—Douglas Barrett!!

A man who was once on par with Rayleigh in Roger's pirate crew!

When the Navy launched the Buster Call to capture him, it was no ordinary Buster Call; even Sengoku and Garp were mobilized.

Otherwise, a normal-level Buster Call wouldn't be qualified to capture Barrett.

Even his grandfather once told him that Barrett was very strong, and when he was captured, he was already stronger than most generals.

This is information known during the Warring States period.

Kyle knew more, such as that Barrett did not become decadent after being imprisoned in Infinite Hell, but instead silently cultivated for 20 years in a state of extreme mental concentration.

Of course, it's not even 20 years yet, only 16 years.

In the original work, Barrett initially displayed immense pressure when facing a large group of pirates.

On the contrary, he was defeated only after using what he claimed to be a stronger Devil Fruit ability; otherwise, he had been dominating everyone until now.

Sigh, it all boils down to those three words: plot-driven death!

"You know me, but I don't know you!"

Barrett glanced at Kyle and then spoke calmly.

"That's normal!"

"After all, I wasn't even born when you were arrested, so it's no wonder you don't know me!"

Kyle spoke up as a matter of course.

Upon hearing this, Barrett's pupils contracted instantly, and his gaze was fixed on Kyle.

"What do you want from me?"

"Nothing much, I just wanted to see what these so-called heirs of the devil look like!"

"Now that I've seen it for myself, I realize..."

Kyle smiled faintly and looked at Barrett as he spoke softly:

"That's all there is to it!"

boom--

The moment he finished speaking, an incredibly powerful surge of Conqueror's Haki erupted from Barrett's body, crushing towards Kyle.

The terrifying Conqueror's Haki was also rampaging across the entire sixth underground level.

All the prison guards lost consciousness the moment they came into contact with this overwhelming color and collapsed.

Even many of the weaker prisoners turned pale, feeling as if their heads had been hit hard by a hammer.

However, Kyle, who was at the center of the Conqueror's Haki storm, did not change his expression at all, and instead showed a faint smile again.

"Is that all? Can you put more pressure on us?"

Barrett remained silent, but became even more ferocious, and a fierce surge of Conqueror's Haki erupted from his body once more.

This time, many prisoners were no longer able to resist the powerful Conqueror's Haki and, like the prison guards, all fainted.

Even among prisoners on the same level six underground, the difference in strength is enormous.

"Ororororo!!"

"How interesting! Douglas Barrett?"

"I remember you!! After being locked up in this godforsaken place for so many years, your Conqueror's Haki still reaches this level?"

"I'm getting involved too!"

Kaido roared, and then an equally powerful Conqueror's Haki burst forth from his body.

Although his entire body was tightly bound by seastone, he could still unleash his Conqueror's Haki.

With the addition of Kaido's Conqueror's Haki, he immediately occupied half of this Infinite Hell, rivaling Bullet's Conqueror's Haki and constantly clashing with it.

Another group of prisoners collapsed.

The entire sixth underground level is now completely enveloped by the Conqueror's Haki of Barrett and Kaido, and one can vaguely see the friction between blue and purple.

Kyle's smile widened as he looked at the other cells on the sixth basement level.

He spoke softly:

"You guys can't get out of here anyway, so why don't you find something to do? How about showing off your Conqueror's Haki?"
