One Piece: The user of the Nen-Nen Fruit, who overturned the sea.

It has been a year and a half since Roy and the others came to Thunder Island to train.

Under Roy's guidance, the members of the Beasts Pirates have all grown considerably.

Jack has been relentlessly training under the pressure of Seastone, and is now able to adapt to a purity of 65%.

Although he is still not as good as the rest of the Roy Pirates, his progress is already quite remarkable considering his starting point.

Runti and Paget's teamwork has become even more seamless, and the siblings have developed a unique combined attack technique—

Runti is responsible for charging and defense, while Page One is responsible for precision strikes.

The two players can now withstand Barrett's attacks for a while, although Barrett isn't using his full strength.

Otherwise, the time it would take them to recover would be enough to match the time they would spend cultivating.

Maria, on the other hand, demonstrated an astonishing learning ability. She not only mastered most of the six techniques,

They also combined the power of the Spider Fruit with physical skills to develop a unique "Spider Web Tactics," which has repeatedly made great contributions in team battles.

Yamato is still the one who has made the most progress, despite being the youngest.

Kaido's bloodline gave her a unique advantage, coupled with her own passion for training.

In a year and a half, her Armament Haki level had caught up with Jack's, and her physical strength was approaching that of the Runti siblings.

"Roy! Watch this!"

Yamato excitedly swung his spiked club, unleashing a basic "Thunder Bagua" strike that actually produced the sound of real wind and thunder!

Roy nodded approvingly:

"Not bad, you already have a bit of your father's style. Keep up the good work, and when you're a little older, you'll definitely surpass him."

"Of course!" Yamato puffed out his chest.

Before they knew it, six months had passed since Roy last returned to Thor Island, and the group had spent another six months there.

That evening, as everyone finished their day's cultivation and gathered to rest on the outskirts, a deafening thunderclap suddenly came from the direction of the core thunder pool!

Immediately afterwards, an unprecedentedly terrifying pressure erupted from the depths of the Thunder Pool!

"It's Tesoro!"

Roy's expression changed, and his figure vanished from the spot in an instant.

The others also rushed towards the direction of the Thunder Pool.

When everyone arrived, the scene before them left them speechless.

In the center of the Thunder Pool, Tesoro floated in mid-air, his entire being completely elementalized, transforming into a ten-meter-tall lightning giant!

Deep purple lightning crackled wildly around him, and the air was filled with suffocating electrical energy.

Most astonishingly, Tesoro's eyes turned completely silver-white, with countless bolts of lightning seemingly flowing deep within his pupils.

"This is... what you called fruit awakening?" Barrett turned to look at Roy, shocked.

"I don't know, I only know that Devil Fruit abilities have an awakening process."

Roy carefully observed Tesoro's condition.

"But I've never seen what fruit awakening looks like."

As Roy finished speaking, Tesoro in the Thunder Pool suddenly opened his arms and roared.

"roar--!!!"

With his roar, the lightning of the entire Thunder Island seemed to be summoned, and it converged madly toward him!

The thunderclouds in the sky swirled, forming a huge vortex. Countless bolts of lightning struck down from the vortex and poured into Tesoro's body!

"Tezzolo is absorbing the energy of the entire island!"

Hawkeye gripped the black knife Night tightly, ready to intervene at any moment.

But Roy raised his hand to stop him.

"Wait, Tesoro is still conscious; he must have his own plans."

Sure enough, after absorbing a massive amount of lightning, Tesoro's aura began to stabilize.

The giant's body gradually shrank, eventually reverting to human form.

But Tezzolo at this point was a completely different person from six months ago.

His skin was faintly covered with lightning patterns, and his eyes occasionally flashed with silver light. His aura was deep and vast, as if he were one with the thunder.

"Boss..."

Tesoro landed slowly, his voice filled with barely suppressed excitement.

"I...I saw it!"

"What do you see?" Roy asked.

"The essence of Thunder".

Tesoro's eyes gleamed.

"It's not simply destruction, but... a rule! The most primal and violent energy rule in the universe!"

He stretched out his hand, and a ball of deep purple lightning appeared in his palm.

However, unlike before, this ball of lightning had fine patterns appearing on its surface, and it did not have the original ferocity of lightning.

"This is..." Roy's pupils contracted slightly.

"I gleaned this from absorbing the lightning in the Thunder Pool."

Tezzolo explained,

"It's still very rough. If I can fully master it, my Rumble-Rumble Fruit will be able to..."

"Awakening," Roy said, providing the answer for him.

"Yes!"

Tezzolo nodded emphatically.

"My Devil Fruit ability has reached its limit. All I need now is a trigger for my 'Rumble-Rumble Fruit' to awaken!"

This news excited everyone.

Fruit awakening—that's a realm countless ability users dream of!

If Tesoro succeeds, his strength will experience a qualitative leap, and he may even directly reach the level of an admiral!

"very good."

Roy patted Tesoro on the shoulder, surprised that he was the first among them to experience the fruit's awakening after eating it.

This made Roy envious, but he still couldn't help but give him some advice.

"Since we need an opportunity, let's not be impatient. Let's continue to strengthen our physical abilities and dual-color Haki."

"Maybe that opportunity will come at any time."

"I understand." Tesoro took a deep breath, suppressing his excitement.

That evening, everyone held a simple celebration.

Although Tesoro has not yet truly awakened, touching the threshold is already a huge breakthrough.

More importantly, this proves that the environment of Thunder Island does indeed have special benefits for ability users.

"Boss, how much longer are we going to have to stay here?"

At the celebration, Savi asked,

"We haven't heard from the PhD student for three months. We don't know how the experiment is progressing."

Roy pondered for a moment,

"Let's wait a little longer. We don't have much time for leisurely cultivation these days."

He looked around at everyone.

"Everyone has made great progress in the past year and a half of training. But the sea will soon be anything but calm."

"Why?" Enel asked curiously. "Boss, have you received some news this time?"

Roy gazed at the distant sea, his eyes deep and thoughtful.

"The situation at sea is changing."

The Roger Pirates should be close to the final island. Although Shiki was defeated by Roger, his ambition will not be extinguished.

The navy is also stepping up its operations... This world is about to undergo a major transformation.

"We need to plan ahead and prepare for the coming era."

"There won't be much time left for quiet training."

Upon hearing this, everyone's expressions turned solemn, and a determined light flashed in their eyes.
