Time flew by.
In the blink of an eye, a month had passed.
On Leon private experimental island, Seraphim Little Kizaru stood on the open grassland, facing Fleet Admiral Sengoku, Garp, and the three Admirals.
"Alright, it's time for the test. Borsalino, let him show us what he's got!"
"Sure!" Kizaru nodded leisurely.
Over the past month, Leon had been busy developing the complete version of the Seraphim, while Little Kizaru had been training.
In fact, it was Leon who had asked Kizaru to oversee the training. So, Kizaru was well aware of Little Kizaru progress.
"Then, Fleet Admiral Sengoku, I'll begin the demonstration."
With Sengoku nod, Kizaru turned to Little Kizaru.
"Little Kizaru, release your dual Haki!"
"Yes."
At that moment, a dark aura surged from Little Kizaru body, instantly enveloping him.
It gleamed with a deep, subdued luster—far more refined and intimidating than the Armament Haki he had displayed a month ago!
Witnessing this, Sengoku and the others couldn't help but tense up.
"He really can train! His Armament Haki has grown stronger!!" Sengoku couldn't hold back his astonishment.
Even though he had mentally prepared himself beforehand, seeing it with his own eyes still left him stunned!
Next, Kizaru lazily raised his hand.
A barrage of Laser Beams shot forth.
This time, Little Kizaru dodged them again. But everyone could clearly sense that his evasion range had narrowed—he was dodging Kizaru attacks with the smallest possible movements!
"His Observation Haki has improved too!"
"Hahaha, well done!" Garp didn't hold back his praise, his words brimming with admiration for Little Kizaru.
Behind him, Akainu and Aokiji wore expressions of shock.
Their eyes reflected the same disbelief!
A man-made robot… could actually train and in just a month, had improved to this extent… This was the mark of an extraordinary genius!
Admittedly, even though they had seen it firsthand, they still found it hard to believe. After all, this completely overturned their understanding of the world.
"But we're not done yet." Seeing their reactions, Kizaru remained calm and spoke again. "Little Kizaru! Show them your swordsmanship!"
"Yes."
With that, Little Kizaru took hold of a sword handed to him. In the next instant, his gaze sharpened, and he suddenly slashed!
"Clang!" A clear sword cry rang out.
A cold gleam flashed as Little Kizaru elegantly swung his blade through the air!
"Whoosh!"
In an instant, a sword wave sliced through the sky!
"Boom!" It struck a distant tree with a resounding impact!
At first, it seemed silent.
The tree appeared unharmed, but the next moment, its upper half smoothly slid off and crashed to the ground! A clean, mirror-like cut—split in two!
"Hmm?" Sengoku and the others were stunned. "He even knows swordsmanship?!"
"When did he learn that?" They turned to Kizaru in bewilderment.
Everyone knew that Kizaru strength wasn't limited to his Haki and Devil Fruit abilities—his swordsmanship was also formidable!
Facing his colleagues' confusion, Kizaru smirked slightly.
"Just a little something I taught him."
Though he said it lightly, Kizaru was brimming with pride inside! This was his little brother masterpiece! And… that's not all!
With that, Kizaru continued speaking. "Aside from swordsmanship, I also taught him a little bit of the Rokushiki."
As soon as the words fell, Sengoku, Garp, along with Akainu and Aokiji, were all utterly stunned.
"Borsalino, don't tell me this little guy knows Rokushiki too..." Sengoku eyes widened in disbelief as he spoke.
If this were true, then the improvement in Haki, the training in swordsmanship, plus Rokushiki... all in just one short month... If he had mastered all of them, wouldn't that mean Little Kizaru talent for training was on par with, if not surpassing, that of the Admirals themselves?
Perhaps even slightly superior!
"Hehe, indeed! But he's only learned the basics, nothing worth mentioning~" Kizaru replied leisurely.
"...Show us!" Sengoku said with a complicated expression.
Garp, Aokiji, and Akainu also watched intently, their eyes unblinking!
"Alright!" Kizaru nodded. "Little Kizaru! Prepare to demonstrate Rokushiki!"
"Yes." Little Kizaru answered expressionlessly.
"First, Tekkai!"
Upon receiving the command, Little Kizaru tensed his body instantly. His muscles tightened, controlling the flow of his blood, and his body became as hard as iron in an instant!
"Soru!" Kizaru spoke again.
No sooner had the words left his mouth, Little Kizaru kicked the ground dozens of times in rapid succession.
The powerful rebound force pushed off the ground! His figure flickered and instantly appeared a hundred meters away!
"It really is Tekkai and Soru!" Sengoku and the others' eyes sharpened.
As top-tier fighters, they could naturally recognize their own signature techniques.
"Continue! Kami-e!"
At Kizaru command, Little Kizaru relaxed his muscles immediately.
His body became as light as a sheet of paper. Dodging and weaving!
"Next, Geppo!"
Little Kizaru obeyed. He kicked fiercely at the empty air, producing a powerful explosive sound. In an instant, his entire body soared into the sky.
"Boom! Boom! Boom!"
Continuous explosions rang out. Little Kizaru body climbed higher and higher into the sky!
"Little Kizaru, use Shigan!"
Little Kizaru expression hardened mid-air as he thrust a single finger forward abruptly.
"Whoosh!"
The sound of the sonic boom alone was enough to convey the immense attack power contained in that single finger!
"Final technique, Rankyaku!"
As soon as Kizaru finished speaking, Little Kizaru raised his right leg in the air and kicked out!
"Whoosh!"
The next moment, a slicing attack burst forth from his foot, streaking straight toward Sengoku and the others!
"Boom!" Garp stepped forward and punched the attack, effortlessly neutralizing it.
"Hahahaha! I never thought he'd really mastered Rokushiki!" Garp couldn't help but laugh heartily.
At this moment, Akainu and Aokiji were also completely astonished.
Especially Akainu, who had now completely dismissed all his doubts about Leon Seraphim!
Sengoku quickly snapped out of his shock as well.
His face immediately filled with delight!
After all, in just one month, Little Kizaru had mastered or improved in dual Haki, swordsmanship, and Rokushiki!
This terrifying rate of progress could only be described as monstrous.
But this monster was on their side, This made him feel nothing short of ecstatic!
"Such growth in just one month. Given more time, our Marines will undoubtedly gain another formidable warrior!!"
