Fruit Development Ideas

Empty Island, God's Island.

Thunder God Palace.

Inside the opulent dining hall with ten-meter-high ceilings, the carved table was laid with shimmering dishes and fine wines.

The crystal-clear juice in the silver goblet, the sizzling meat on cloud trays, the stewed shellfish bathed in broth—every rare delicacy gleamed in abundance.

But in Seven's eyes, these offerings, revered as treasures, barely reached half the culinary skill he possessed.

Still, they counted as genuine good food.

Having successfully awakened Armament Haki, he deserved a full half-day off—slowing down his eating pace to truly indulge.

Seven lifted the silver cup for a sip, his gaze sweeping over Shani, who stood at attention with lowered eyes.

"Sit down and eat with me."

"As you wish, Lord Thunder God."

Shani smoothed her skirt, stepped forward, and pulled out a chair, her movements gentle but stiff with restraint.

Casual chatter accompanied the clink of cups. Shani occasionally shared tales of Empty Island's customs, while Seven spoke of his experiences on the sea.

Since becoming the god of Empty Island, he had never savored food so slowly or elegantly.

This dinner stretched on for two and a half hours, the relaxed atmosphere like the drifting clouds in the hall, making time itself seem to vanish.

The plates were cleared, and the table returned to its pristine state.

Shani lifted her head, her clear eyes reflecting the scattered light of the cloud-crystal chandelier. "Lord Thunder God, could I... learn swordsmanship from you?"

"Swordsmanship?" Seven set down his silver cup. "Why do you want to learn that?"

Shani's voice grew clearer than before. "I want to grow stronger... to protect Empty Island like you do."

Seven rubbed his brow. I'm no Great Swordsman, but I'm still a swordsman—shouldn't lead anyone astray.

Protect Empty Island? Looks like Gan Fall's propaganda worked well: Kizaru was successfully painted as the evil villain trying to invade Empty Island.

The one who drove off the evil villain Kizaru—Lord Thunder God Beelzebul—became Empty Island's guardian god by default.

"Go rest early. Come by tomorrow morning with Shalou."

"Thank you."

If Shani had wanted to learn anything other than swordsmanship, Seven truly couldn't teach it. The only thing he had to offer was Conqueror's Haki Infusion, and that required awakening Conqueror's Haki first.

Armament Haki? He'd just started—couldn't teach that.

Fruit ability development? Even less likely.

His own development of the Rumble-Rumble Fruit was still at a basic stage; he couldn't even generate magnetism from electricity.

Sitting in his chair, Seven let electric sparks of various colors dance at his fingertips, trying to create a magnetic field from electric current.

Electricity and magnetism are inseparable.

Where there's electricity, there's magnetism; where there's magnetism, there's electricity.

That saying isn't entirely accurate, though. Only moving charges or changing electric fields produce magnetic fields—static charges have none.

And generating electricity from magnetism—

Magnetic field particles must move fast enough for their kinetic energy to overcome electron inertia, pushing electrons to create current.

In short, if Seven wants to create a magnetic field from electricity, he needs to set the charges in motion.

Relatively simple.

The reason he wanted to generate magnetism from electricity was inspired by the Super Electromagnetic Cannon listed on the Trading Platform.

Code
[Super Electromagnetic Cannon: 20,000 points. The electric light dancing at your fingertips is my eternal faith. Seller's note: Long live the Super Electromagnetic Cannon, forever and ever.]

Who doesn't love the Railgun, after all?

If he developed the Rumble-Rumble Fruit to a certain level, Seven could completely replicate the Super Electromagnetic Cannon—without even needing to toss a coin.

Well, tossing the coin is the soul of it.

Generating magnetism from electricity to unleash the Super Electromagnetic Cannon was one of Seven's ideas for developing the Rumble-Rumble Fruit.

Beyond that, once he mastered electromagnetism, he might even be able to receive electromagnetic waves and brainwaves, greatly amplifying his Observation Haki.

Telepathy would come naturally then.

Also, the speed of light and electromagnetic waves are the same—light itself is an electromagnetic wave.

These were the finer points of developing the Rumble-Rumble Fruit. For bigger, stronger applications, Seven currently only had ideas like Thunder Welcome and the Thunder God Form.

Thunder Welcome, the ultimate move Enel developed in the anime, was one of the few attacks in the Pirate World capable of destroying an entire island in one blow—on par with the Ancient Weapons.

If he ever ran into a major scene like the Summit War, Seven could just drop a Thunder Welcome.

Whether it blows up or not is another matter—the intimidation factor alone would be maxed out.

The Thunder God Form, inspired by Susanoo, was the direction Seven had set for developing the Rumble-Rumble Fruit. For now, it existed only in his imagination.

An even higher level of awakening for the Rumble-Rumble Fruit—Seven had no clue how to achieve it. Still, he figured the system shop should sell Fruit Awakening.

50,000 points? 100,000 points?

For him right now, that was far out of reach.

Shoving aside those lofty ambitions, Seven flickered to the domed bedroom atop the Thunder God Palace and drifted off to sleep under a sky full of stars.

In a courtyard west of the main hall of the Thunder God Palace, two chattering voices cut through the silent night.

"Sis, I can't sleep."

On the pristine white bed, Shani hugged her knees, squeezing her ample curves into different shapes.

Shalou, with her short hair, ignored her sister's unfairly stacked figure and glanced down at her own flat chest.

"Sleep or don't, I don't care."

The next day, dawn lit up the White Sea.

Thunder God Palace, Martial Arts Arena.

Seven stood in a black training suit, a wooden sword in hand. With a casual swing, he sent a Flying Slash cutting through the air, then fixed a calm gaze on Shani and Shalou.

"The core of the sword is intent and momentum, not brute force."

"Of course, if you're strong enough, brute force can work miracles too."

"Follow the method I just taught you. From now on, swing your swords ten thousand... three thousand times a day."

The two sisters wore the same black training suits, but they carried them with completely different flair: Shani was curvaceous, her every move seemingly magnetic, while Shalou radiated a stubborn, youthful grit.

"Yes, Lord Thunder God."

Teaching these sisters swordsmanship was nothing more than a casual pastime for Seven.

He didn't care how well they learned, nor did he expect these two young girls to become top-tier fighters. It was just a bit of flavor to spice up his monotonous training.

On the other side of the Martial Arts Arena.

Thirty Thunder Cloud Guards stood in silver armor, holding spears embedded with Slash Shells, their formation as straight and orderly as pines, waiting solemnly for the Lord Thunder God's inspection.

Seven flickered to the front of the Thunder Cloud Guards, pulled a strip of black cloth from the system space, and blindfolded himself.

"Starting today, attack me with your weapons. I won't fight back."

"Yes! Lord Thunder God!"

Thirty voices rang out in unison, the sound shaking the air slightly.

After more than three months of working together, Seven had long since earned the absolute submission of the Thunder Cloud Guards through sheer force. Now, they held nothing but reverence and unquestioning obedience for him.

After awakening Armament Haki.

Seven set his sights on Observation Haki, choosing the most direct and simplest method to explore it: taking hits.

The black cloth blocked his sight. Seven actively shut down his ability to predict through electric waves, completely emptying his mind, relying solely on his body to sense the flow of everything around him.

The path of the wind, the tremors in the air, and the auras and heartbeats of the thirty Thunder Cloud Guards—all grew clearer in his perception.

"Clang—clang—clang—"

Sharp slashes released from the Slash Shells landed on Seven one after another, the crisp sound of metal striking metal echoing through the arena.

Those attacks, strong enough to split cloud rock, struck his Iron Balloon body without leaving even a faint white mark, only the dull thuds of impact.

The Thunder Cloud Guards' movements all paused. Their hands tightened unconsciously on their weapons, disbelief filling their eyes.

"Keep going."

Clang~ clang~ clang~

Each dodge honed his perception, sharpening his ability to track auras.
