The Strongest Vice Captain In The Future Is Born

"Yes, this is a Devil Fruit that will definitely attract countless forces when it hits the market."

Kahn first gave Robin a thumbs up, then pretended to be amazed: "When I first overheard this information, I couldn't believe it."

"Unexpectedly, it has become a legend in the 'Devil Fruit Illustrated Book'. Rumble Fruit, one of the invincible Logia abilities, has reappeared on Sky Island 10,000 meters above."

"Rumble Fruit?"

"It turned out to be the Rumble Fruit?!"

Hearing Kahn's words, the three Boa sisters, who didn't have a deep understanding of Devil Fruits, were only slightly taken aback.

Robin's beautiful eyes widened as she looked at the Devil Fruit in Hancock's hand in great surprise.

"Sister Robin, what abilities does the Rumble Fruit have?"

Seeing that Robin, who was usually extremely calm, suddenly reacted this way, Mary couldn't help asking curiously.

Hancock and Sonia also cast curious glances at Robin.

Robin took a deep breath and began explaining to the three Boa sisters: "Devil Fruits are divided into three categories: Paramecia, Zoan, and Logia."

"Within these categories, there are subtypes, like Master's Devil Fruit, which is a Zoan type, Dragon-Dragon Fruit, Model: Azure Dragon, which is rarer than Logia."

"Logia, however, has no subtypes."

"Logia is recognized in the 'Devil Fruit Illustrated Book' and in all popular books as the strongest type among the three categories of Devil Fruits."

"Each Logia represents a natural element between heaven and earth."

"Among these natural elements, lightning is always at the top and is one of the most feared natural disasters."

"So, whoever eats the Logia Rumble Fruit will be able to control the power of lightning."

After finishing, Robin looked at the Devil Fruit in Hancock's hand and slightly sighed: "Just like what Master said, even among the three types of Devil Fruits, the Logia Rumble Fruit is one of the most invincible abilities."

"Hiss..."

Robin's explanation was very detailed.

Even the three Boa sisters, who didn't know much about Devil Fruits, could clearly understand the treasure that Master had given them.

Sonia and Mary gasped in shock.

Although Hancock didn't lose her composure, her hands holding the Logia Rumble Fruit trembled slightly.

She felt that the fruit in her arms suddenly became extremely heavy.

The preciousness and value of the Logia Rumble Fruit made the proud Hancock feel unconfident. She looked at Kahn and asked, "Master, do you really want to give me such a precious Devil Fruit?"

"Of course!"

Seeing Hancock's lack of confidence, Kahn stepped forward, put his hand on Hancock's head, ruffled her hair, and said with a smile: "Robin, Mary, and I are already Devil Fruit users. You and Sonia are the only ones left without abilities."

"The reason I didn't give you the Paramecia Construct Fruit yesterday is because you are the most talented among us. When I was twelve, I hadn't even mastered Armament or Observation Haki."

"With your talent, only a top-tier Devil Fruit is suitable for you. Only a top-tier Devil Fruit can stimulate your potential the fastest."

"As long as you eat the Logia Rumble Fruit, you'll have the strength to protect your sisters and the ability to repay me."

After speaking, Kahn pinched Hancock's beautiful face, which now looked delicate and cute.

"I understand."

Hearing Kahn's last words, Hancock's expression suddenly became firm.

As the Master said, only by gaining great power can she protect her sisters and repay the Master's kindness.

However, Kahn's life-saving grace and investment in her and her sisters made the innocent Hancock, like Robin, see Kahn as the Master of her life.

Unknowingly, her heart had been shaped by Kahn.

Unless Kahn ruthlessly killed Sonia and Mary or manipulated events for them to be killed by Hancock herself, it's certain that even after thirty years, Hancock would not be willing to leave Kahn's side.

In Hancock's heart, the balance between Amazon Lily and the Master had completely tilted towards Kahn.

So, Hancock looked at Kahn seriously and echoed her sister: "Master, I will not let you down."

With that, Hancock held the Logia Rumble Fruit, opened her mouth, and bit off a piece of the fruit.

Knowing that Devil Fruits tasted terrible, Hancock only frowned slightly as she chewed the pulp.

Zizizi...

After swallowing the pulp, Hancock threw away the remaining fruit and began to feel changes in her body.

After a few seconds, an astonishing number of blue and white electric snakes suddenly flashed from Hancock's body.

The ear-piercing electric sound scared Mary and Sonia back a few steps, and they rubbed their bodies vigorously with both hands.

Almost the moment the electric snakes appeared, Sonia and Mary were covered in goosebumps.

"What... what a powerful ability!"

Hancock, whose body was shining with blazing electric light, was also full of shock at this time.

She raised her hands, first looking at the palms surrounded by electric snakes, then at the balcony of the suite, trembling as she said: "Is this the Logia Rumble Fruit, the invincible ability?"

"Sister, what is your ability?"

Hearing this, Sonia and Mary subconsciously wanted to step forward and ask.

But when they saw the lightning around Hancock, they stopped immediately, choosing to stand behind Kahn, looking at Hancock with surprised faces, and asked.

Pulled back to her senses by her sister's voice, Hancock said excitedly: "I haven't figured out the specific abilities yet, but the range of my Observation Haki has skyrocketed countless times in an instant."

"And my Observation Haki can now eavesdrop on external conversations like the Master, with negligible energy consumption."

"Hiss..."

Both Sonia and Mary were too shocked to speak.

Robin said calmly: "It seems that the Logia Rumble Fruit also possesses an invisible power similar to telekinesis, which greatly enhances Observation Haki."

"Ah... I read the 'Devil Fruit Illustrated Book' when I was a child, and this should be one of the Rumble Fruit's basic abilities—electric wave." Kahn nodded.
