"Plunder!"

As Rowen's command echoed in his mind—two brilliant golden lights were extracted from Enel's falling body and absorbed by Rowen.

——

—[Plunder successful! Acquired: Rumble-Rumble Fruit (Deep Gold)! Observation Haki (Deep Gold)!]—

—[Physique energy contained within Rumble-Rumble Fruit (Deep Gold) automatically digested. Superhuman Demonic Physique (Deep Gold) Enhanced!]—

—[Born of the Sea (Apex Gold) activated! Armament Haki (Deep Gold) Enhanced!]—

——

A notification screen appeared.

All of Enel's power—was now Rowen's.

The Rumble-Rumble Fruit (Deep Gold) Trait contained all of Enel's physical energy, along with his intense desire to be lightning, developed through using the fruit's power.

Regarding this, the moment Rowen obtained the Rumble-Rumble Fruit, feedback from the System confirmed: Enel—who proclaimed himself God, the incarnation of lightning—his desire to be lightning had already reached the threshold required for the fruit to Awaken!

The only reason it hadn't Awakened yet was because Enel's physique hadn't met the necessary conditions.

For a Devil Fruit like Rumble-Rumble—arguably one of the most powerful in existence—to Awaken, the user's physique had to reach the Apex Gold tier!

Enel's physical energy yielded the equivalent of seven Deep Gold tier physique Trait materials for Rowen.

Though Enel's hand-to-hand combat skills were abysmal, his innate affinity with the Rumble-Rumble Fruit's desire (reaching the Awakening threshold), combined with the fruit's constant tempering of his body, meant his physique contained astonishing energy.

No wonder Enel could use the Ark Maxim to simulate the Rumble-Rumble Fruit's Awakened power, even unleashing terrifying attacks like Raigo, capable of obliterating an entire Sky Island!

Physique energy didn't equate directly to physical strength—it was also the 'FUEL' for Devil Fruit abilities. Enel being able to provide such vast energy to the Ark Maxim showed he was only one step away from Awakening.

It was just unfortunate that Enel first encountered Luffy, whose Nika rubber body completely nullified his lightning, and now, Rowen, who had mastered Infused Conqueror's Haki. His life had met its decisive end.

This plundered physique energy existed within every cell.

Even if Enel expended vast energy during his fight with Rowen and died brutally, the cellular physique energy wouldn't dissipate immediately—

—Only through centuries of continuous, life-or-death struggle, like Dorry and Brogy, causing complete exhaustion of cellular energy, would it affect the total amount. Or, of course, after death, physical energy naturally dissipates over many years.

Now, Rowen's Superhuman Demonic Physique (Deep Gold), after absorbing Enel's physique energy, was only one Deep Gold Trait material away from reaching the Apex Gold tier!

And that final piece—Rowen looked towards the Observation Haki (Deep Gold) Trait he'd plundered from Enel.

He had two choices: directly use it to enhance his own Observation Haki, or convert it.

Observation Haki was also a Strength-type Trait—

Rowen's own Observation Haki was already Apex Gold, capable of briefly seeing the future—placing him among the absolute top Haki masters on the seas.

Amplified by the Rumble-Rumble Fruit's electric waves, its range was terrifyingly vast.

Rowen closed his eyes.

CRACKLE! CRACKLE!

His entire body dissolved into dazzling lightning.

The Rumble-Rumble Fruit's power amplified his Observation Haki range even further—Incredibly vast!

Rowen smiled.

After equipping Aisa's innate, super-high-level Observation Haki, his sensory range already covered the entirety of Upper Yard.

Now, amplified by the Rumble-Rumble Fruit, it expanded a staggering TENFOLD—

Such terrifying sensory range, combined with his Apex Gold Observation Haki capable of briefly foreseeing the future—Even if the World Government sent a massive fleet to hunt him, they could never catch him...

Forget a fleet—even individual Intelligence Agents trying to track him—Rowen's Haki, amplified by lightning waves, could sense their hostile intent and use the Rumble-Rumble Fruit for long-range strikes, eliminating all possibility of being found...

Unless Rowen 'chose' to reveal himself, no one on these seas could find him now.

Yet Rowen could monitor a vast expanse of ocean, holding absolute battlefield initiative.

Essentially, Rowen was now truly undefeatable in a strategic sense.

Furthermore, Rowen discovered the Rumble-Rumble Fruit could also assist in training Observation Haki!

By using electric waves to amplify Haki, the fruit essentially turned the user into a living antenna, receiving information from vast distances—thereby expanding the sensory range of Observation Haki.

This, in turn, effectively broadened the influence of the user's manifested five senses.

With an increased range and volume of sensory input, the user's manifested senses were constantly exercised, thereby strengthening their Observation Haki intensity.

Enel, ignorant of Haki's true nature (calling it 'Mantra')—still managed to reach Deep Gold Observation Haki precisely because of the Rumble-Rumble Fruit's training assistance.

With this ability, Rowen didn't need Enel's Observation Haki (Deep Gold) Trait to further enhance his own. Besides, at Rowen's current level, absorbing Enel's Haki would provide minimal improvement.

Converting it into a fixed Upgrade Material was the optimal solution.

"Convert!" Rowen commanded inwardly.

——

—[Conversion successful!]—

——

Enel's Observation Haki (Deep Gold) was converted into one Deep Gold Strength-type Upgrade Material.

(The Rumble-Rumble Fruit only amplified Haki range, not intensity. Enel, for instance, couldn't sense any of Rowen's movements through Haki—

And this training method, while consistent, wasn't as effective for raw intensity increase as life-or-death combat sharpening the manifested senses. Enel's Haki was just barely Deep Gold.)

But this single Deep Gold material was exactly what Rowen needed!

"Enhance!"

Without hesitation, Rowen applied the converted material to his Superhuman Demonic Physique (Deep Gold).

——

—[Superhuman Demonic Physique (Deep Gold) meets upgrade conditions! Advancing to: Superhuman Demonic Physique (Apex Gold)!]—

—[Born of the Sea (Apex Gold) activated. Armament Haki (Deep Gold) enhanced. Due to insufficient spiritual power, reached Armament Haki (Deep Gold) limit.]—

——

A notification appeared.

Physique—successfully promoted to Apex Gold!

Though adding directly to the physique Trait, the hunger was manageable; after all, it was only a one Deep Gold level increase to his already substantial nine Deep Gold levels worth of physique energy—a mere 1/10th deficit, not requiring immediate eating.

However, seeing Armament Haki only reach 'Deep Gold limit' instead of Apex Gold was perplexing.

Armament Haki combined spiritual power and physique energy. All along, Rowen's Conqueror's Haki had been the limiting factor.

Now, with physique at Apex Gold, his Conqueror's Haki (Deep Gold) became the bottleneck, preventing Armament from reaching Apex Gold.

Fortunately, the reward for ringing the Bell of Shandora—that vast 400-year spiritual power awaited—and Born of the Sea would continue to strengthen his Conqueror's Haki.

Reaching Apex Gold was inevitable.

Although Armament Haki didn't advance a full tier, the abundant physique energy resolved Rowen's previous stamina issues with Haōshoku Coating.

Haōshoku Coating, though pure spiritual power, still consumed immense physical stamina to wield its violent energy.

Previously, his Deep Gold physique couldn't fully sustain its terrifying consumption—his body would give out before his Haki did.

Now, with Apex Gold physique, that problem was solved! As long as his Conqueror's Haki held out, Rowen could continuously unleash Haōshoku Coating!

His control over it also improved, boosting its attack and speed enhancements. After all, power needed a strong wielder; abundant physical energy allowed 100% manifestation of that power.

And the gains didn't stop there!

——

—[Physique energy meets Awakening conditions! Desire to 'BE LIGHTNING' meets Awakening conditions! Rumble-Rumble Fruit Awakening conditions satisfied!]—

—[Rumble-Rumble Fruit—AWAKENED!]—

——

A notification appeared!

Devil Fruit users, even meeting the desire and physique conditions, faced a difficult trial to Awaken their fruit.

Even Luffy, with protagonist plot armor, was beaten unconscious by Kaido before his Sun God Trait finally triggered Awakening.

But Rowen, with the Strongest Trait System—once the physique and desire conditions were met—DEVIL FRUIT AWAKENING WAS AUTOMATIC!

The Rumble-Rumble Fruit—one of the most invincible abilities—At this moment, in Rowen's hands—AWAKENED!

BOOM! CRACKLE! CRACKLE! CRACKLE!

Rowen transformed entirely into a Lightning Human, ascending from Upper Yard high into the White-White Sea...

Terrifying bolts of lightning, within Skypiea's unique environment, seemed to pierce the Sky—

Lightning even more dreadfully violent than Enel's now raged through the atmosphere and the White-White Sea. Deafening thunderclaps echoed endlessly—like the wrath of a True God!

Only upon Awakening could the Rumble-Rumble Fruit's full power be unleashed.

After Awakening, the Devil Fruit's abilities reached their absolute peak!

Rumble-Rumble Fruit (Apex Gold)!

The Trait tier instantly leaped to Apex Gold!

Even relying solely on this fruit, without any Haki, Rowen now possessed Admiral-level combat strength!

This—was the fearsome power brought by a true top-tier Devil Fruit!

<><><><><><><><>

"ROWEN!"

At that moment, Luffy, Zoro, and the others rushed over. Nami, Vivi, and Robin; Wyper, Gan Fall, and the others—all stared dumbfounded at Rowen, now like a Thunder God, hovering in the vast White-White Sea.

"L-LIGHTNING?! ENEL'S POWER?!" Gan Fall and Wyper stared in horror at the Thunder God Rowen.

And was it their imagination, or did Rowen's lightning seem even stronger than Enel's?!

"Rowen can take other people's Devil Fruit abilities and use them himself—"

Usopp explained, though his forehead was beaded with cold sweat, he still managed a proud tone while looking at the horrifying, sky-piercing lightning Rowen controlled.

"S-So scary! The power of the Rumble-Rumble Fruit," Zoro and Sanji swallowed hard.

As expected of an ability desired by Rowen—the power of lightning, fit for a God!

This destructive force, in Rowen's hands, was leagues above even the Flare-Flare Fruit!

Of course, they didn't know Rowen's Rumble-Rumble Fruit was now Awakened, unleashing its full potential—naturally far stronger than his current mastery of the Flare-Flare Fruit.

And—

Zoro, Sanji, and Luffy clutched their heads, expressions of pain twisting their faces as the terrifying thunderclaps echoed through the sky.

"R-ROWEN! OUR OBSERVATION HAKI—IT'S NOT WORKING!" Zoro yelled, a hint of horror in his voice.

No... not exactly 'not working'—but the moment they tried to activate it, it was instantly overwhelmed by the deafening roar of thunder!

"The Rumble-Rumble Fruit's power can overwhelm your Observation Haki. Unless your Observation Haki is trained to its absolute limit—it's useless before this fruit's power,"

Rowen turned, looking down at Zoro and the others on the edge of Upper Yard, a smile on his face.

After Awakening, the Rumble-Rumble Fruit's power was unleashed to its extreme.

Unless one's Observation Haki reached Apex Gold, it would be overwhelmed by the 'Thunder Sound'.

It was, in a way, an 'Observation Haki Nullification'—USING DEVIL FRUIT POWER TO COMPLETELY SHUT DOWN HAKI PERCEPTION!

"As expected of one of the most invincible abilities among Devil Fruits," Robin murmured, utterly amazed.

The display of the Awakened Rumble-Rumble Fruit was too outrageous...

Aokiji's Ice-Ice Fruit, which had once left her with deep psychological scars, seemed significantly weaker in terms of raw destructive display.

And... the power of Awakening didn't stop there!

"Witness—the true power of Devil Fruit Awakening!" Rowen declared, looking towards Luffy, Robin, Vivi, and Chopper—the four Devil Fruit users—his body thrumming with crackling electricity!

"DEVIL FRUIT AWAKENING???" The others' pupils constricted.

Thanks to Rowen's explanations, they knew only after Awakening could a Devil Fruit unleash its full power, and each type gained unique, wondrous abilities!

The next moment—

VMM!

A strange ripple emanated from Rowen's entire body!

CRACKLE!

Affected by this ripple, a vast expanse of the White-White Sea's clouds suddenly began to change!

CRACKLE! CRACKLE! CRACKLE!

Countless arcs of lightning, like coiling thunder serpents, began to writhe violently within them! The white clouds darkened, eventually transforming into raging thunderclouds, constantly roaring with untamed lightning!

Logia Devil Fruit Awakening Ability—

Permanently alter the climate of an area—

These clouds were now permanently thunderclouds—

BOOM!

Under the stunned gazes of everyone present, the lightning within these newly formed thunderclouds suddenly struck downwards!

"MAMARAGAN (HEAVY THUNDER)!!!"

Rowen stood at the center of countless thunderclouds, like a true Thunder God, laughing triumphantly!

CRACKLE! BOOOOOOOOOOM!!!

Innumerable bolts of lightning rained down!

CRASH!

Far below, the White Sea at 7,000 meters—under the bombardment of ten thousand thunders—had massive holes blasted through it!

Logia Devil Fruit Awakening—this was true, unadulterated—Natural Disaster!

Everyone stared blankly at the spectacle, their eyes filled with absolute, utter horror.

This scene—looked like power capable of—DESTROYING THE WORLD!
