Recruit Luffy at the start and build the strongest navy.

Under Kyle's control, the massive lightning spear, imbued with an aura that could pierce through everything, crashed down upon Zephyr below.

A terrifying aura swept over them, causing the five people hiding behind a large rock in the distance to tremble.

The five people strained to open their eyes, barely managing to open them a crack under the overwhelming aura. The few eyes that were visible were filled with horror.

"When did Kyle become so strong?!"

Ace's voice was tinged with shock and disbelief.

He found it hard to accept; everyone was still a child, so why was he so outstanding?

The fact that Kyle is two years younger than him is a huge blow to him!

"Did he never use his full strength when he fought us before?"

"The gap is so huge! It's laughable that we thought we could beat Kyle after just a few days of training!"

"If I were Kyle, I'd find what the three of us just said ridiculous, wouldn't I?"

Saab was so discouraged that he lost some confidence.

As the second oldest of the four, he always looked up to the eldest brother. Although he was easily defeated by Kyle when the battle determined who was the eldest brother, he never expected the gap to be so huge!

He can barely withstand the aftershocks of Kayle and Zeff's battle, let alone fight Kayle. How can he possibly catch up with that kind of strength?

On the other side, Kuina and Zoro looked at each other, completely bewildered.

Although they had just watched the fight between Kyle and Koushirou a few days ago, the fight they saw then was on a completely different level from the one they were seeing now.

At that time, Kyle and Koushirou were simply exchanging sword skills, at most using their Haki.

Visually, it's far inferior to Kyle's ability.

At that moment, a confident shout rang out, startling all four of them.

"Kyle, I will definitely surpass you!!"

All four of them turned their gazes toward Luffy, who showed no sign of being discouraged; instead, he displayed confidence and anticipation for his future.

The four could see the shock Luffy felt at Kael's strength in his eyes, but what they saw even more was his confidence that he would one day surpass Kael.

At that moment, everyone was stunned, staring blankly at Luffy.

Just a few seconds later, a strong light suddenly flashed in the eyes of the four men, and an inexplicable aura surged from them, completely erasing their previous defeated appearance.

Instead, they exuded boundless vitality and the same confidence in their future.

Sabo, Ace: If the fourth brother is confident of surpassing the eldest brother, how could the second (third) brother not have the same confidence?

Kuina, Zoro: This little brat who looks like he's not even grown up dares to spout nonsense, how could they be worse than this brat?

So, instead of being discouraged by Kael's display of strength, everyone became even more eager to try after Luffy's shout.

However, Kyle was unaware of their thoughts at the time, otherwise he would have been greatly pleased.

Foolish little brother, keep chasing after my retreating figure! Until the day your heart stops beating!!

But Kyle certainly doesn't have time to think about these things right now; he's completely focused on the battle with Zeff.

This was the first time he had ever unleashed his power so recklessly, a power he hadn't even surpassed when he gave the Red-Haired Pirates a thunder bath.

This feeling of fighting to my heart's content... it's so exhilarating!!

Kyle, thoroughly enjoying himself, couldn't help but burst into laughter and shouted down:

"Zeff, are you even capable?! All those muscles are just for show?"

As soon as these words were spoken, a terrifying aura suddenly exploded below, blowing away all the surrounding smoke and dust.

"Just for show? Kyle, you really dare to say that! Have I been too lenient with you, and now you think you're all that?"

"I'll tell you today why you call me 'teacher,' not the other way around!"

As soon as he finished speaking, Zephyr's aura surged, and with a "ripping" sound, he put on a spectacular clothes-ripping show for Kyle and the others hiding behind the big rock.

Even at sixty years old, Zefa's muscles remained incredibly strong, with a sculpted, knife-like outline.

The next moment, Zephyr's figure vanished from the spot, and almost at the same time, Kyle felt an extreme threat coming from the side. His expression changed drastically, and he immediately transformed into lightning and fled.

However, when he appeared in another location, he found himself shrouded in a dark shadow. He subconsciously looked up and saw Zephyr's smiling face.

"Got you!"

Before he could finish speaking, Zephyr's fist came crashing down, the Armament Haki wrapped around it gleaming with a dark luster, seemingly flowing subtly.

Kyle only had time to cross his arms in front of him and apply Armament Haki.

boom--

Zephyr's fist landed heavily on Kyle's crossed arms, the powerful force bursting forth and creating a shockwave, sending Kyle flying backward like a cannonball.

Before Kyle could fly far, he felt darkness fall before his eyes again.

Zephyr appeared above him, and the two flew through the air parallel to the ground.

Zephyr smiled again and kicked Kyle hard.

"You brat, get down here!!"

Bang! !

A dull thud followed, and Kyle was kicked squarely again, his body plummeting downwards at incredible speed.

On the way, Kyle's body suddenly turned into lightning and landed on a large rock below in the blink of an eye.

Of course, it's not the one Luffy and his crew are hiding from.

Boom!!

A huge explosion was heard, and the massive rock instantly shattered, sending fragments flying in all directions.

Countless stone chips and dust floated in the air.

Tiny purple lightning bolts spread outwards along the ground.

Zefa used Moonwalk to continuously tread in the air, making himself float in the air. Looking down, a smile involuntarily appeared on his lips.

"You brat! Let's see if you dare to mock this old man again!"

Knowing that Kyle's physique was abnormally strong, Zephyr didn't hold back at all with his punches and kicks.

This will at most make Kyle suffer a little, but it's impossible to kill him.

Sure enough, not long after, a bolt of purple lightning shot out from the smoke and dust, soaring into the sky and reaching a height of about ten meters above Zephyr, revealing Kyle's figure.

Kyle rubbed his chest with his right hand, grimacing, and looked at Zephyr, saying:

"Zeff-sensei, you really don't hold back!!"

"Isn't this the result you wanted, kid?"

Zefa spoke in a calm voice.

"That's true!"

Kyle nodded.

"If you don't unleash your true power, teacher Zephyr, the battle will indeed be very boring!"

Zefa raised an eyebrow and spoke with a forced smile:

"Kyle, looks like I didn't teach you enough of a lesson earlier!"

"Then you haven't eaten enough, shall we practice some more?"

Kyle replied calmly.

The two stared at each other in mid-air, then, as if sensing something, they simultaneously charged towards each other...
