"What!? Your eight-year-old brother wants to join the Navy Science Division??"
At Navy Headquarters, inside the Fleet Admiral's office.
Sakazuki stared at Kizaru in utter disbelief, shouting out loud in agitation.
Aokiji and Garp were also present in the room. After hearing what Kizaru had just said, both of them revealed puzzled and confused expressions.
Kizaru—Borsalino.
Normally, the fact that he wasn't particularly enthusiastic about work was tolerable. After all, he still showed up to clock in every day; he wasn't skipping work outright. So everyone usually turned a blind eye.
But this time?
He was trying to stuff a relative into the Navy Science Division—one of the most important departments in the entire Navy.
If the kid actually understood technology, that would be one thing.
But the person he was trying to push in was an eight-year-old brat!
Forget understanding science—he probably hadn't even mastered addition, subtraction, multiplication, and division yet. Letting a child like that enter the Navy Science Division was completely absurd.
"Borsalino, I know you want your younger brother to earn a salary to help support your family," Sakazuki said sternly. "But the Navy Science Division is an extremely important department. Sending your eight-year-old brother there—isn't that just causing trouble?"
Even the usually easygoing Aokiji couldn't hold back anymore and joined Sakazuki in criticizing Kizaru.
Vice Admiral Tsuru sighed helplessly and shook her head, looking rather troubled.
These days, pirates across the seas were increasing at an alarming rate. The Navy was already overwhelmed as it was. Now Kizaru was adding more nonsense into the mix—life in the Navy was only getting harder.
Garp, on the other hand, looked completely unconcerned.
"An eight-year-old going to the Navy Science Division? Hahaha! Interesting! Really interesting!" Garp laughed loudly while stuffing senbei into his mouth.
Tsuru shot him a glare.
Only then did Garp finally behave himself.
Kizaru scratched his head awkwardly and looked around at everyone.
He hadn't expected his colleagues to react so strongly to this matter.
It seemed his habit of slacking off at work had already built up quite a bit of resentment...
Oh, my foolish little brother Xia Yu…
Your big brother can only help you this much!
Looks like if you can't pass these people's tests, there's no way you'll smoothly enter the Navy Science Division and draw a salary…
At that moment, the door to the Fleet Admiral's office suddenly opened.
Fleet Admiral Sengoku walked in, leading along an eight-year-old boy.
The child had a round little head that looked clever and lively. His small figure waddled forward with childish steps, his skin pale and delicate—like a porcelain doll.
His bright, large eyes carried a hint of cunning.
This adorable eight-year-old was none other than Kizaru's younger brother—Xia Yu.
"Hello, everyone. Please don't blame my brother. I was the one who begged him."
"But don't worry. I'll enter the Navy Science Division with my own abilities. You just need to remove the age restriction for me!" Xia Yu said in a soft, childlike voice.
Vice Admiral Tsuru immediately felt her maternal instincts surge. She gently patted Xia Yu's round little head.
"Haha! What a cute child. But don't make such big claims. The Navy Science Division has very high requirements when it comes to technological knowledge," Tsuru said warmly.
Garp, Akainu, and Aokiji all looked toward Kizaru with curious expressions.
They simply couldn't understand how someone with Kizaru's appearance could possibly have such a handsome and adorable younger brother.
In truth—
Xia Yu was a genuine transmigrator.
Eight years ago, he had transmigrated into this world as a newborn baby—coincidentally becoming Kizaru's younger brother.
Because he retained the memories from his previous life, he displayed extraordinary intelligence even at the age of eight.
More importantly…
He had arrived with a system.
And his system was called the Infinite Technology System.
As long as he had sufficient funding, he could endlessly unlock world-defying technologies.
Of course, the required funding was enormous.
Just yesterday, after saving every bit of pocket money for eight entire years, living frugally the whole time—
He had finally developed the first Seraphim ahead of Vegapunk!
But… this pace was far from enough.
In this world, the only people capable of supporting the massive funding required by his technology system were the Celestial Dragons.
And if he wanted to develop even more technologies, there was no better place than the Navy Science Division.
Coincidentally, he now had the perfect "letter of introduction"—
The Seraphim.
That was why today he had cried, caused a scene, and practically threatened to hang himself just to beg his brother Borsalino to introduce him.
"Of course I understand that, Sister Tsuru. Next, let me show you my invention."
Hearing Xia Yu call her "Sister Tsuru," she smiled even more brightly.
"Come out—Seraphim Kuma," Xia Yu said calmly.
At the doorway of the Fleet Admiral's office, a chubby mechanical boy suddenly stepped forward.
Everyone nearby turned their heads toward it, their faces filled with confusion.
?
A child appeared?
No… something was wrong with this child.
Why were there flames on his wings?
Could it be…?
Was this a child from the Lunarian race?!
"This is a humanoid weapon created using the Lineage Factors of three individuals—Warlord Kuma, Lunarian King, and my brother Kizaru," Xia Yu explained.
What?
A humanoid weapon?!
It looked unbelievably realistic…
In fact, its appearance really did resemble Bartholomew Kuma when he was younger.
Regardless of how strong the machine was in battle—
The mere fact that an eight-year-old child already understood how to utilize Lineage Factors alone made him a true genius.
"You said just now that this is a humanoid weapon?"
Sengoku looked intrigued.
"Then let me ask you—how does this child robot compare to the Pacifista?"
If its strength surpassed that of the Pacifista, then the Navy could absolutely consider mass production.
Of course, words alone meant nothing.
They needed to see its combat performance first.
"The difference?"
Xia Yu smiled faintly.
"It's enormous."
"First of all—basic abilities like laser beams, superhuman physical strength, and life regeneration."
Everyone moved to the training ground.
Seraphim Kuma began its demonstration.
A terrifying laser beam shot out, instantly blasting apart a small mountain near the naval base—completely overwhelming the Pacifista's firepower.
Before anyone could even react—
The next moment, Seraphim Kuma moved several hundred meters in an instant.
With a single punch—
It smashed a massive abandoned steel warehouse over a hundred meters away into fragments.
Even more terrifying was its regenerative ability.
After being injured and bleeding, the wound stopped bleeding, formed a scab, and regenerated brand-new skin in less than a second.
Seeing Seraphim Kuma's performance, these normally composed high-ranking naval officers all stood frozen in shock, mouths hanging open.
"Little brother… the power of that laser is almost on par with mine!" Kizaru said in astonishment, his eyes wide behind his sunglasses.
"That speed—did it just use Soru from the Navy's Six Powers?! And that explosive strength—it's at least ten times stronger than a Pacifista!" Even the usually carefree Garp became serious.
"Is that really a machine? It can even bleed?! And that regeneration is outrageous—it's comparable to the powers of top-tier Zoan Devil Fruits!" Aokiji exclaimed, covering his mouth in shock.
Sengoku, Sakazuki, and the others were so stunned they couldn't even speak.
They could only stand there in a daze, swallowing nervously.
They understood better than anyone what it meant if such a machine could be mass-produced.
If every naval branch had even one of these…
Pirates across the Grand Line would be completely wiped out.
Even Vegapunk—the world's greatest scientist who was said to be 500 years ahead of current technology—couldn't achieve something like this.
If they hadn't seen it with their own eyes, they would never have believed it.
And yet—
It had been created by an eight-year-old child.
What a monstrous genius!
The future of the Navy looked bright!
After a long while, Sengoku finally recovered from his shock and walked toward Xia Yu.
"You little brat… impressive!" Sengoku said excitedly, patting Xia Yu heavily on the shoulder.
"The Navy is going to rise! Xia Yu, you are the Navy's lucky star!" Vice Admiral Tsuru said, her eyes gleaming.
Kizaru looked incredibly smug.
This was his biological younger brother—his success brought honor to him as well.
Let's see who dares say I'm using nepotism now!
If any of you can shove in a relative whose technology surpasses even Vegapunk's, then go ahead!
Meanwhile, Xia Yu remained completely calm, unmoved by all the praise.
"This is nothing," he said indifferently.
"These are only the most basic abilities."
"I haven't even shown its core power yet."
"It also possesses both types of Haki… and the power of the Paw-Paw Fruit."
The moment those words were spoken—
The Navy's top brass exploded into chaos.
Everyone's heads filled with question marks and exclamation marks!
