The following day, Aizen, the key figure that Kōki and his group had been waiting for, finally arrived.
"Main body, have you dealt with the matters on the Kumogakure battlefield? We don't know how long this experiment will last." Aizen Kōki.
"It's all taken care of. I specifically set aside a Wood Release Clone with half my strength to oversee the battlefield. With him there, most situations can be resolved without delaying our crucial experiments."
Kōki had great confidence in the power of his Wood Clone.
Moreover, he still has the trump card of Sage Mode. If he really can't handle it, his Wood Release Clone will also find an opportunity to enter Sage Mode to deal with the situation.
In any case, it won't affect this important experiment.
Kōki looked delighted.
He truly hadn't expected that his freely roaming clones would bring him such a great gift.
"In that case, let's begin to avoid any unforeseen complications." Hearing what the main body said, Aizen no longer hesitated and immediately indicated that he wanted to conduct the experiment.
Kōki naturally had no objection and nodded in agreement.
So they came to Uchiha Ryuko's side.
At this moment, Uchiha Ryuko had been injected with an anesthetic by Aizen and was in a coma.
"As for the main body, what's next? The original work didn't explain the specific steps involved in merging the two Mangekyō."
"I considered this issue when I received your message. Initially, I was also worried about the specific procedures, fearing that incorrect procedures might cause damage to the Mangekyō Sharingan."
However, I then remembered that in the original work, Uchiha Sasuke's eyes and Itachi's eyes were actually on the verge of exhaustion, which means that the power of both pairs of Mangekyō Sharingan was about to be completely depleted. But after Uchiha Sasuke transplanted Itachi's eyes, he regained his sight and they became Eternal Eye.
This gave me a clue: the fusion of the Mangekyō Sharingan is more about the complementarity of genes or origins than the fusion of eye powers.
Therefore, we'll try the simplest method: remove Uchiha Ryuko's eyes and replace them with Uchiha Seika's eyes, then observe the changes in Uchiha Ryuko.
"As long as the origins of the two pairs of Mangekyō Sharingan are similar, after transplantation, the two origins will complement and merge into a more perfect one, and this one will form the Eternal Mangekyō Sharingan."
I even speculate that the complementarity of these Mangekyō Sharingan is a fusion at the Chakra level. We all know that whether it's Kekkei Genkai, secret techniques, or Ninjutsu, everything is composed of Chakra. Even the most special Sharingan cannot be separated from the realm of Chakra. Therefore, the Eternal Eye is very likely formed by the combination of special Chakra residing in the Mangekyō Sharingan of two relatives.
"So we don't need to be too nervous, just operate normally."
Although Kōki couldn't guarantee that all his thoughts were correct, he was more than 80% confident that this fusion would be successful, because it was based on his deeper understanding of Chakra gained from healing the wounded on the battlefield.
Hearing what Kōki, who was most skilled in Medical Ninjutsu, said, Aizen had no more reservations and began to cooperate with Kōki's eye transplant experiment.
This transplant surgery was not difficult for Kōki, and he quickly removed Uchiha Ryuko Mangekyō Sharingan and replaced it with Uchiha Seika's Mangekyō Sharingan.
"Alright, let's verify my guess with one eye first."
Looking at Uchiha Ryuko, whose right eye was wrapped in medical bandages, Kōki said, "Judging from the time Sasuke Uchiha to awaken the Eternal Mangekyō Sharingan in the original work, it will probably still be some time. So, for the time being, I will stay here until I confirm that this method is successful and obtain the Eternal Eye, then I will leave."
So, for the next few days, Kōki would go to Uchiha Ryuko's side every day to observe the changes in the Chakra within Uchiha Ryuko's body.
In Kōki's perception, the changes in Uchiha Ryuko's Chakra were very obvious, with a significant increase every day.
Fortunately, he later applied Sealing Jutsu to Uchiha Ryuko, otherwise, things might have really gotten complicated.
However, this change only confirmed Kōki's suspicions.
It is indeed possible to obtain the Eternal Eye through transplantation. However, he was not in a hurry to transplant the other Mangekyō Sharingan onto Uchiha Ryuko, because he wanted to have more time to observe the process of Eternal Eye.
Perhaps this awakening process can provide some inspiration.
Finally, on the fifth day, a mysterious and captivating Eternal Eye, composed of patterns from two different Mangekyō Sharingan, appeared before Kōki and the others.
Just as Kōki was about to remove the newly acquired Eternal Mangekyō Sharingan, an unexpected event occurred.
The Eternal Eye before them suddenly emitted a powerful ocular force, instantly invading Aizen and Jörmungandr's minds and directly attacking their spirits.
They never expected that Uchiha Ryuko, who had been cooperating with their experiments, would suddenly turn on them.
Therefore, they were completely caught off guard and were directly struck by this powerful pupil force.
However, since Aizen others were driven by Kōki's Special Shadow Clone, being hit by the eye power had no effect on them; it just meant that the clones were temporarily offline.
This situation seemed to surprise the owner of the eye power, who immediately turned his attention to invading Kōki's mind again, seemingly preparing to control Kōki.
Unfortunately, the owner of this eye power miscalculated. If he had attacked Kōki directly, he might have succeeded, because although Kōki's spirit was not weak after splitting into Special Shadow Clone, it was still not as strong as when he was not splitting.
However, Uchiha Ryuko chose to attack Aizen and Jörmungandr first, which caused Kōki's scattered mental energy to instantly return to his body, making it much more difficult to control Kōki.
Furthermore, the special clone had been learning and training on Aizen's body for so long that it could completely ignore this kind of Genjutsu after returning to the body.
Therefore, Kōki immediately realized that it was very likely that Uchiha Ryuko broke through the seal on his body when he awakened the Eternal Eye, and then controlled the Eternal Eye to attack him.
Therefore, Kōki didn't waste any time and directly used Wood Release to absorb the Chakra within Uchiha Ryuko's body.
With the appearance of Wood Release, the Chakra within Uchiha Ryuko's body rapidly depleted, and the Eternal Mangekyō Sharingan in his eye sockets degenerated into ordinary eyes.
"As expected, one should be more careful the closer one gets to success. I kept telling myself to be cautious, but I still let my guard down in the face of such a treasure. Uchiha Ryuko, you've taught me a lesson."
Kōki had always thought he was being very careful, but this time, the allure of the Eternal Eye was too great, causing him to lower his guard. He couldn't help but berate himself for being careless.
At the same time, he felt fortunate that he had come in his true form. If it had been a clone, he might have been successfully ambushed by Uchiha Ryuko, and his achievements would have even exposed the true nature of the Light Organization.
