Seeing that the time was right, Naruto took the scroll containing the sealed Rinnegan of Urashiki's right eye from his ninja tool pouch and broke the seal.
He reached out with his left hand, aiming at his own right eye. Under Urashiki's gaze, Naruto's right eye, under the precise control of Absolute Control, detached from his eye socket, and was extracted intact along with the optic nerve bundle..The entire process didn't shed a single drop of blood.
Naruto sealed his original right eye into another blank scroll, then picked up Urashiki's blue Rinnegan and placed it into his right eye socket.
The moment the Rinnegan entered the socket, his visual nerve endings completed the connection with the Rinnegan's nerve bundle, with every single nerve fiber precisely connected to the correct position.
The residual Chakra mark within the Rinnegan was wiped away by Absolute Control and the ocular power structure inside the eyeball was reactivated.
After doing all this, all the abilities contained within the Rinnegan flooded into Naruto's mind.
The insight of the Byakugan, the space-time travel ability of the red six-tomoe Rinnegan, and the Temporal Rewind of the blue Rinnegan.
Then, right in front of Urashiki, Naruto began to switch the Rinnegan in his right eye. The iris transformed into the blue Rinnegan, with ripple-like patterns unfolding layer by layer around the pupil, then it switched to the red six-tomoe Rinnegan, then to the Byakugan, and finally cycled freely between the three.
"Such an interesting power, I'll gladly accept it."
While switching the dōjutsu modes of his right eye, Naruto gave Urashiki a meaningful smile. He raised his left hand, pointing his finger at Urashiki's only remaining left eye.
"Then, I won't be polite about taking your other Rinnegan."
At this moment, Urashiki was completely stunned. He stared blankly at Naruto freely switching between the three dōjutsu modes with his right eye. His overflowing rage was completely extinguished at this moment by a surge of ecstasy welling up from the depths of his heart.
Such a high compatibility rate?
Naruto was the perfect vessel he had been desperately searching for.
He had lived for over a thousand years and had searched for a vessel, but not one had achieved this level of compatibility with the Rinnegan.
Urashiki suddenly threw his head back and laughed. "Hahahaha... Take it. Don't you want the Rinnegan? Take it all. Hahahaha!"
Naruto paused, a puzzled expression appearing on his face as he stopped the movement of his left hand.
"Did I beat your brains out?"
Urashiki's laughter stopped abruptly, replaced by a meaningful sneer.
Time Freeze!
An invisible force spread out from Urashiki as the center, and Naruto felt the surrounding space transform into a sealed cage. His body was completely unable to move.
"Hahaha... My perfect vessel. You want the Rinnegan, don't you? Take it."
The time freeze also froze the suppressive power of the chains, allowing Urashiki to free one hand from the Adamantine Sealing Chains.
He pressed his palm against Naruto's chest. Naruto clearly sensed wave after wave of power pouring into his body. These forces did not fuse with the Chakra already in his body, but instead compressed within him, eventually forming a dark red cube.
Kāma!
The ultimate resurrection method of the Ōtsutsuki Clan: compressing and packaging all of their genetic data to inject into a vessel's body, waiting for the data to slowly decompress and overwrite the vessel's entire body, allowing the Ōtsutsuki to be resurrected within the vessel.
This was exactly what Naruto had been waiting for.
He allowed Urashiki to pour all of his data into the cube within his body.
A moment later, Urashiki finished injecting the last bit of data, and a smile appeared on his pale face.
"Hahaha... Naruto, we will meet again." Urashiki sneered at Naruto, who was frozen in time.
His body began to turn to ash inch by inch from his fingertips. The ashes hovered in the still air for a moment before being scattered by a gust of wind.
Naruto felt a sense of realization as the blue Rinnegan in his right eye began to wither irreversibly.
With the demise of Urashiki's true body, the Rinnegan was losing its ocular power at an extremely rapid rate. Naruto invoked Absolute Control to try to stop this process, but after a second thought, he stopped.
Since Urashiki was already inside him, once he finished parsing the data in the Kāma, he would not only be able to restore this Rinnegan but also gain all of Urashiki's abilities.
Naruto clenched his fist and the corners of his lips curled upward. He then took out the scroll that had sealed his original right eye from his ninja tool pouch and placed his original right eye back into his eye socket.
The nerve connection was completed and his vision was restored, exactly as it had been before.
After finishing all this, he looked into the distance.
Sasuke was half-kneeling on the ground, one hand supporting his knee, the other gripping the Kusanagi Sword, which was stabbed into the ground, his chest heaving.
The previous use of Amenotejikara had almost completely drained the little Chakra he had left.
Naruto nodded at Sasuke.
Seeing Naruto nod, Sasuke's tense nerves finally relaxed, and he leaned back, collapsing onto the ground.
Seeing Sasuke fall, Boruto immediately jumped out of his hiding spot. He ran to Sasuke's side and draped his arm over his shoulder.
Watching Sasuke become so weak after using Amenotejikara just once, Naruto couldn't help but shake his head.
With a Rinnegan and a Kusanagi Sword, yet he collapsed after using Amenotejikara once. He looked even more disheveled now than a Genin crawling out of the Forest of Death.
"Dad!"
Boruto helped the staggering Sasuke walk up to Naruto.
"I didn't expect that you had even mastered Adamantine Sealing Chains."
Sasuke's gaze fell on the few lingering traces of golden chains on Naruto's right hand that hadn't completely dissipated yet.
Adamantine Sealing Chains was a Fuinjutsu passed down through generations of the Uzumaki clan. He had been fortunate enough to see Karin use it once but he had never seen it on any other member of the Uzumaki clan since.
"Adamantine Sealing Chains?" Boruto blinked in confusion, clearly having never heard the name before.
Naruto smiled slightly and deactivated Kurama Mode. The golden Chakra cloak receded and the Magatama turned into specks of golden light, dissipating into the air.
Clatter!
He raised his right hand and several chains formed by golden Chakra extended from his palm once more. With a flick of his wrist, the chains wrapped around Boruto, swaying him left and right in mid-air.
"Adamantine Sealing Chains is a Kekkei Genkai of the Uzumaki clan. You have the blood of the Uzumaki clan flowing in you, so theoretically, you have this talent. As for whether you can awaken it, that depends on your own efforts."
Boruto shouted excitedly: "So cool, can I awaken it too?"
He started imagining himself running through the streets of Konoha while swinging the golden chains in his mind.
Naruto retracted the Adamantine Sealing Chains. The chains turned into golden specks of light and dissipated into the air, and Boruto landed on the ground.
Naruto turned to Sasuke. "Urashiki has been dealt with. Let's return to Konoha first, your current state requires rest."
Sasuke was silent for a moment, then nodded.
He had a belly full of questions he wanted to ask Naruto. The Naruto of this timeline obviously knew many things he shouldn't know—from the Ōtsutsuki Clan to the Rinnegan, and even Urashiki's abilities—he understood them in more detail than he himself, who had personally fought Urashiki several times.
But now he couldn't even stand steadily, so these questions would have to wait until they got back to Konoha and he recovered.
Naruto extended his hands toward the two of them. Boruto and Sasuke extended their hands and the moment the three of them touched, the Flying Thunder God Technique was activated.
Swish!
A flash of golden light passed, and the three figures vanished on the spot.
After an unknown amount of time.
A white object rose from the soil at the edge of the battlefield. A grotesque smile was plastered on its face, its gaze sweeping suspiciously over the devastated battlefield.
A moment later, a spatial vortex unfolded by the riverbank and Obito stepped out from within.
Entire groves of trees had been uprooted, the ground was pitted and scarred with impact marks, and several types of Chakra fluctuations he had never sensed before lingered in the air.
"Another battle has occurred." Obito muttered to himself.
It had been less than two days since the last battle at the border. Such a frequency of Kage-level clashes was extremely rare in the history of the Ninja World.
"Who was it this time?"
He pressed his palm against the ground to sense for a moment and firmly memorized the remaining Chakra of this battlefield. Then he activated Kamui once more to depart.
