What?!
The people around them felt as if a magnitude ten earthquake had just erupted inside their minds after hearing Xia Yu's words.
Garp and Sengoku exchanged glances, both seeing the same shock reflected in each other's eyes.
What a shocking statement!
Haki… Devil Fruits…
No one understood the significance of those two things better than they did.
And now—
Xia Yu was telling them that a machine possessed them?
That was impossible… completely impossible!
Vice Admiral Tsuru widened her eyes in disbelief.
Haki and Devil Fruit abilities were things unique to humans.
If a robot could wield both Haki and Devil Fruit powers, then what difference would there even be between it and a human?
This machine was so realistic it was almost terrifying.
Sakazuki also stepped forward, staring at Seraphim Kuma with a suspicious expression.
How could a machine possibly understand Haki?
And Devil Fruits could only be eaten by humans. What method could a robot possibly use to obtain the power of a Devil Fruit?
This was simply too absurd to believe.
"A machine like this exists in the world?" Sakazuki narrowed his eyes. "You're not lying to us, are you, brat?"
"Watch your mouth. My little brother doesn't lie," Kizaru said protectively.
"Brother, don't argue. I'll show everyone right now."
Xia Yu spoke in his childish voice.
"Seraphim Kuma—show them your Armament Haki first."
Sakazuki, Aokiji, and the others immediately revealed expectant expressions. Their eyes locked onto Seraphim Kuma, not blinking for a moment, afraid they might miss even the smallest detail.
As if it could understand Xia Yu's command—
The Seraphim Kuma, which had been standing still moments earlier, suddenly moved.
A layer of pitch-black armor, like polished obsidian, began to form across Kuma's shoulders.
Garp and the others activated their Observation Haki.
Through their perception, they discovered that Seraphim Kuma's Armament Haki was no different from a human's.
In fact, it had already reached the level of basic Ryuo!
"That feeling… that really is Armament Haki!" Sengoku exclaimed in delight.
"And it's already at the level of Ryuo! Unbelievable!" Garp's eyes widened exaggeratedly.
No one present understood Armament Haki better than Garp.
If he said the machine had reached the level of Ryuo, then there was no doubt about it.
"If it also possesses Observation Haki and a Devil Fruit ability… then this machine might already be at the level of the Seven Warlords of the Sea," Tsuru said in shock, swallowing nervously.
Akainu also stood frozen in place.
A robot possessing Haki—a power that only humans should have?
And it was real?
Even Kizaru's mouth hung open in astonishment.
My little brother…
Is he really this incredible?
How did I never notice before?
Looks like I've been a pretty terrible big brother.
Such a brilliant technological genius existed right in my own family, and I had no idea—despite working in the Navy's science department!
"Next—don't stop. Show them Observation Haki," Xia Yu calmly gave another command amid the crowd's amazement.
Sakazuki still seemed unwilling to accept it and stepped forward.
"I'll test it personally."
A magma-covered fist erupted from Akainu's body.
The surrounding air instantly became scorching hot.
Of course, Akainu was holding back.
This child was the Navy's future hope—he had no intention of damaging the invention.
The attack wasn't extremely powerful, but its speed was terrifying.
The blazing magma fist shot forward, arriving in front of Seraphim Kuma in an instant.
The light in Seraphim Kuma's eyes flickered.
In the next moment—
It made a perfect sidestep, smooth and fluid.
The massive magma fist brushed past its body and flew out to the side.
Boom!
Dozens of meters behind Seraphim Kuma, the blazing fist exploded violently.
Molten magma erupted outward, blasting a massive crater into the ground.
Meanwhile—
Seraphim Kuma remained standing exactly where it had been.
Completely unharmed.
"Good! Good! Good!" Garp applauded excitedly.
Sengoku's heart was also racing with excitement.
Judging from the Haki test alone, this machine had already reached the combat level of a Warlord of the Sea.
Who could have imagined that Kizaru's younger brother was a once-in-a-millennium genius scientist?
With technology like this, the explosive growth of pirate forces since the era of Pirate King Roger could finally be suppressed.
"It actually worked… Xia Yu is absolutely the greatest genius I've ever seen!" Tsuru's eyes shone with brilliant light.
Sakazuki's eyes widened in shock, his voice trembling slightly.
"It… it actually dodged my attack… unbelievable."
Everyone else also revealed expressions of excitement.
"Seraphim Kuma—continue!"
"Show them your Devil Fruit ability!" Xia Yu ordered.
The surprises kept coming.
The Navy's top brass hadn't even recovered from the shock of seeing a machine wield Haki.
Now Seraphim Kuma was about to demonstrate a Devil Fruit power.
Hearing Xia Yu's words, Sengoku, Garp, and the others immediately focused their attention again, staring intently at Seraphim Kuma.
Every one of them looked eager and curious.
What kind of ability would it be?
Most likely some artificial Zoan Devil Fruit ability developed by Vegapunk.
Something like that would still be useful—it could enhance physical strength.
But the next moment—
They were completely stunned.
The Devil Fruit ability Seraphim Kuma displayed was exactly the same as the one possessed by Bartholomew Kuma.
Not a single difference.
A massive paw-shaped shockwave gathered in Seraphim Kuma's hand.
Then—
It fired the attack toward an abandoned fortress over a thousand meters away.
Boom!
The enormous shockwave detonated upon impact.
The entire fortress was instantly blown into powder, and even the ground trembled under the force of the blast.
The surrounding area suddenly fell silent.
Not a single person spoke.
This reaction even left Xia Yu slightly confused.
What was going on?
Earlier, when I hadn't finished demonstrating yet, all of you were showering me with praise.
Now that I've finished, no one is going to compliment me?
Xia Yu felt somewhat helpless.
After a long while…
Sengoku and the others finally recovered from their shock.
It wasn't that they didn't want to speak.
It was just that the abilities displayed by this machine were simply too monstrous.
Originally, they thought that possessing an artificial Zoan ability would already be impressive.
But what they witnessed was far beyond their expectations.
The machine actually possessed the Paw-Paw Fruit ability of Bartholomew Kuma!
Its combat strength was practically on par with the real Kuma.
No—
That wasn't quite right.
This machine also possessed the power of Kizaru and the Lunarian race.
That meant it was even stronger than Kuma himself.
Starting level—
Warlord of the Sea!
