Naruto: From Konoha to One Piece

The Impure World Reincarnation Jutsu did not meet expectations, leaving Shin slightly disappointed.

"In addition to the Impure World Reincarnation Jutsu, perhaps only by using the Outer Path — Samsara of Heavenly Life Jutsu (Rinne-Rebirth Jutsu) can I truly pose a threat to the World Government."

"However... Rinne-Rebirth Jutsu follows a life-for-life rule. One must sacrifice the user's life to grant life. According to research, no matter how vast one's chakra reserves or how strong one's vitality is, this cost cannot be avoided. It is a fundamental rule."

"Whether the Revive-Revive Fruit can circumvent this rule is a big question."

"And if the Revive-Revive Fruit tries to escape... who knows what kind of unexpected situation might arise?"

"Forget it. No matter what, the Impure World Reincarnation Jutsu is just an external force. The most important thing is my own strength."

Currently, after awakening both the Munch-Munch Fruit and the Dark-Dark Fruit, Shin had made some progress in power. However, these two Devil Fruits were not primarily attack-based. If they were, he would have dared to challenge Imu head-on by now.

"However, for me, the real path to power lies in the fusion of Devil Fruits."

Looking at the Eight-Headed Serpent Fruit and Azure Dragon Fruit in his hand, Shin's lips curled into a smile.

The connection between dragons and snakes is undeniable, especially in mythical creatures like the Eight-Headed Serpent, which are deeply intertwined with dragon lore. This provides a solid foundation for fusion.

"Two top-tier Mythical Zoan Fruits—plus, the Azure Dragon Fruit itself possesses various elemental abilities like cloud, flame, lightning, and wind. More Devil Fruits can be incorporated in the future."

"The Eight-Headed Serpent Fruit could be merged with some toxin-based Devil Fruits. Additionally, whether it's a dragon, fish, or snake, they can all integrate with other Devil Fruits."

"If I could merge a few more Devil Fruits, then no matter who stands in my way may it be the World Government or Celestial Dragons, I'd make sure to crush them all!"

With that thought, a wave of black energy surged forth. The Azure Dragon Fruit, covered in dragon scales, and the Eight-Headed Serpent Fruit, with its eight-forked leaves, began merging.

The cyan dragon scales turned half black and half red, while each of the eight forked leaves sprouted tiny horns. The newly fused Devil Fruit was complete.

Shin set aside the Soul-Soul Fruit and took a bite of the newly combined Devil Fruit. Instantly, a surge of overwhelming power coursed through his body.

Zoan-type Devil Fruits provide immediate enhancements even when their abilities are inactive, subtly improving the physical fitness of the user. However, what Shin felt now was different. It was a raw, unmistakable surge of strength—something he had never experienced before. Even when he first ate the Azure Dragon and Eight-Headed Serpent Fruits, the growth had been gradual.

Only when he first used Ace's body structure for human transformation, or when he fused with Hashirama's cells, had he felt such a drastic increase in power.

"ROAR!" With a long, resonating howl, Shin's body stretched and transformed, becoming an eight-headed, eight-tailed dragon clad in dark scales, with horns atop each head.

Countless flame clouds floated around him, and in an instant, the massive dragon soared into the sky.

"Whoa! That's a massive dragon! And why does it have so many heads?" Ryuma, the Dragon Slayer Swordsman, who had been idling, looked up in shock.

Meanwhile, Charlotte Pudding, Violet, and the others immediately recognized traces of the Azure Dragon Fruit's power in Shin's transformation.

"Mr. Shin, could it be that you have fused a new Devil Fruit? It seems far stronger than the original Azure Dragon Fruit."

"It must be a Mythical Zoan! This power..." Ryuma marveled as he watched the colossal dragon spewing flames, lightning, and fierce winds. "If I had faced a dragon like this, I would've been done for! Shin's Devil Fruit is ridiculously strong!"

After testing his abilities for a while, Shin reverted to his human form and landed back on the Thriller Bark.

At that moment, Ryuma, who had been honing his swordsmanship after his revival, approached him.

"Captain Shin, I heard that you can fuse Devil Fruits... was that one combined with the Eight-Headed Serpent Fruit?"

Shin paused before nodding. "I didn't expect you to recognize the Eight-Headed Serpent Fruit. Speaking of which, I obtained this Devil Fruit in Wano. Could it be that it has some connection to Wano? It doesn't seem to appear anywhere else."

Shin had heard that some Devil Fruits circulated predominantly within certain regions and rarely left. This was especially common with Zoan-type Fruits, which were said to have an innate sense of belonging.

For instance, the Tontatta Kingdom frequently had insect-based Zoan Fruits, and Alabasta often yielded jackal or vulture-type Fruits. These Devil Fruits seemed to instinctively recognize their native lands and rarely appeared outside of them.

Fruits like the Eight-Headed Serpent Fruit, which were virtually nonexistent outside of Wano, fell into this category.

A nostalgic expression crossed Ryuma's face. "Yes! I once encountered a user of this Devil Fruit. I cut off his head, but he resurrected, which startled me quite a bit."

"But speaking of resurrection, Captain Shin... you're even more incredible. You can bring the dead back to life."

A spark of realization flashed in Shin's mind, and he quickly asked, "What did you just say?"

Ryuma blinked in confusion. "I said, Captain Shin, you're amazing. You can resurrect the dead."

"No, before that."

"Uh... that the Eight-Headed Serpent Fruit allows resurrection even if one's head is cut off?"

"Yes, that!" A grin spread across Shin's face. "If a user can resurrect even after decapitation, then if the Impure World Reincarnation Jutsu is lifted, can they still come back to life?"

"Captain Shin, are you suggesting...?"

Without hesitation, Shin activated the Munch-Munch Fruit's ability, splitting the Eight-Headed Dragon Fruit and extracting the Eight-Headed Serpent Fruit again.

"Here, eat this—quickly!"

"Uh... isn't this a bit too precious?" Ryuma hesitated.

Shin rolled his eyes. "I'm lending it to you, not giving it away permanently."

"Oh..." With that, Ryuma took a decisive bite of the Eight-Headed Serpent Fruit.
