Uchiha Arata asked, "System, when will my Eternal Mangekyō Sharingan evolve into the Rinnegan?"
"Replying to the host. Due to missing essential conditions, the host's Eternal Mangekyō Sharingan cannot currently evolve into the Rinnegan."
Arata was stunned.
In his understanding, Uchiha Madara had awakened the Rinnegan by transplanting Senju Hashirama's flesh into his own body before dying of old age. Later, Madara implanted those eyes into Nagato, trained Uchiha Obito, and laid down the groundwork for his eventual resurrection.
That was why Arata found this result hard to accept. He believed that he already possessed the same conditions as Madara—if not better. Not only had he fused Senju blood, but he now also possessed a complete Sage Body. Logically, he should awaken the Rinnegan even faster than Madara.
Sensing his confusion, the system provided a detailed explanation.
"Replying to the host. Uchiha Madara was the reincarnation of Indra and possessed Indra's chakra. Senju Hashirama was the reincarnation of Asura and possessed Asura's chakra. When Madara transplanted Hashirama's flesh, he effectively gained both Indra and Asura's chakra, allowing him to awaken the most basic form of the Rinnegan after decades of fusion."
Arata touched his chin thoughtfully. He hadn't expected Madara and Hashirama's identities to be so complex, nor that awakening the Rinnegan required possessing the chakra of both Indra and Asura.
Still puzzled, he asked, "Why must one possess both Indra and Asura's chakra to awaken the Rinnegan?"
"Replying to the host. Indra and Asura are the sons of the Sage of Six Paths. They inherited the Sage's Immortal Eyes and Immortal Body respectively, representing the original Yin and Yang chakra. Only by possessing and perfectly fusing both can one form the power of all things and awaken the Rinnegan."
Arata frowned slightly. Awakening the Rinnegan was far more troublesome than he had expected.
Impatient, he asked, "That's too complicated. Is there any other way?"
"There are five possible methods, listed from easiest to most difficult, for the host to choose from."
"First: Obtain the chakra of Indra and Asura. The system will assist in catalyzing fusion. Estimated time to awaken the Rinnegan: two years."
"Second: Collect the chakra of all nine tailed beasts and allow the system to fuse them. Estimated time: three years."
"Third: Capture Nagato, the current owner of the Rinnegan. Copy the Rinnegan's ocular techniques, then allow the system to catalyze fusion. Estimated time: three years."
"Fourth: Gather all tailed beasts, resurrect the Ten-Tails through the Demonic Statue, become the Ten-Tails Jinchūriki, and directly obtain the Rinnegan."
"Fifth: Plant a Divine Tree, harvest its chakra fruit, and consume it. This will grant the Nine-Tomoe Rinnegan directly."
Arata stared at the list, the corner of his mouth twitching violently.
The first few methods were still acceptable. With his current strength, they were achievable.
But the last two were simply insane.
Starting the Fourth Great Ninja War, or outright exterminating the planet?
Especially the final method—planting the Divine Tree and harvesting its fruit—would essentially wipe out all life. Even if Arata could accomplish it, everyone on the planet would be dead. Was he supposed to go challenge the Ōtsutsuki clan afterward?
At his current strength, Arata already stood at the very peak of the ninja world. Even if Uchiha Madara were resurrected, he would pose no threat. If Arata wished, Madara and Obito would never be able to gather the tailed beasts, resurrect the Ten-Tails, or launch the Infinite Tsukuyomi.
He could simply capture the Three-Tails and seal it inside his space, permanently preventing the tailed beasts from ever gathering.
But Arata could not do that.
He still had to consider the future.
Within twenty years, members of the Ōtsutsuki clan might descend upon this planet. If his strength stagnated, how would he resist them? Moreover, there was already an Ōtsutsuki lurking somewhere in the ninja world. As long as that being didn't act, Arata had no intention of provoking trouble.
Among all methods, the first was clearly the simplest.
Beside him were the reincarnations of Indra and Asura—Uchiha Sasuke and Uzumaki Naruto.
And after his Mangekyō evolved into the Eternal Mangekyō Sharingan, Arata's pupil technique, Eye of Replication, could copy even bloodline limits and chakra, including that of Indra and Asura.
In other words, Arata already possessed the perfect opportunity.
Otherwise, finding their reincarnations among countless people would be nearly impossible. And once they fully matured, controlling them would become extremely difficult.
