"There are two methods, but I cannot guarantee success."
"And I already have a substitute; once we return to the Ninja World, I will help him acquire it."
Uchiha Tamahiko said to Fugaku very cautiously.
After all, this was a father's hope.
Most importantly, he wasn't 100% confident; he could only say it was an opportunity to try.
"What are the two methods?"
Fugaku quickly asked.
He wasn't afraid that Uchiha Tamahiko would harm his son; rather, he was worried that the method would consume too much of the clan's manpower and resources.
If it required too much, he would choose to give up.
"The first is what I mentioned: the First Hokage's cells can help the Uchiha Clan improve their genes and strengthen their physical constitution."
"This method can minimize the side effects of the Mangekyo Sharingan, almost preventing blindness, but I cannot confirm if it can restore vision to eyes blinded after using Izanagi."
Uchiha Tamahiko raised his index finger and explained to Uchiha Fugaku.
He felt the success rate wasn't high, but Uchiha Madara had used his own eyes for Izanagi, faking his death to deceive the First Hokage.
At the same time, after using the First Hokage's flesh, he awakened the Rinnegan, restoring his blinded eyes and regaining light.
However, Uchiha Tamahiko was unsure if a normal Mangekyo could achieve such an effect.
"What about the second one?"
After hearing this method, Fugaku also felt it was indeed unclear, as clan records indicated that no one who used Izanami had ever recovered their sight.
He then pressed for the second method, eager to know the possibility of success.
"The second is the mutual exchange of Mangekyo Sharingan between close relatives."
"Before Uchiha Madara, no one had ever succeeded. Even during clan infighting, seizing a Mangekyo only amounted to replacing with new eyes, not restoring the Mangekyo's vision."
"The exchange of Mangekyo Sharingan between close relatives has a certain possibility of awakening a higher level of the Mangekyo Sharingan, reaching the Eternal Mangekyo Sharingan. With the evolution of the Mangekyo Sharingan, there is a high probability of restoring vision to blinded eyes."
Uchiha Tamahiko explained the second method.
He currently possessed not the Eternal Mangekyo, but a perfect Mangekyo, the perfect state of the Uchiha bloodline.
The true Eternal Mangekyo was only possessed by Uchiha Madara and Uchiha Sasuke, but both were reincarnations of Indra. Uchiha Tamahiko couldn't confirm if only Indra's reincarnations could awaken the Eternal Mangekyo.
After all, during the Uchiha Clan's internal conflicts, when they abused the power of the Mangekyo, they also tried to seize the eyes of other clan members who had awakened the Mangekyo. However, like Kakashi, they could only use the Mangekyo's visual jutsus of the new eyes, but it did not make the Mangekyo's side effects disappear.
As for Uchiha Madara and Uchiha Sasuke, the recipients of the Mangekyo exchange, one was given to Uchiha Madara before his near-death, and the other was collected by Obito after death and replaced when Sasuke's eyes were almost blind.
Neither of the two who died had the opportunity to exchange their older brother's or younger brother's eyes, so it was impossible to confirm whether both parties could benefit and similarly awaken the Eternal Mangekyo.
After Uchiha Madara faked his death with Izanagi, it was more like his eyes evolved and restored his blindness.
"I see, this method is indeed feasible."
This matter had been discussed among the higher-ups before; Uchiha Tamahiko had not hidden the secrets of the Uchiha.
He had only kept silent about the reincarnation of Indra.
After hearing the method Uchiha Tamahiko described, Fugaku found it feasible.
"Then let's try with my eyes."
"I'm old now, and my potential is far less than Itachi's. He carries more hope."
Fugaku quickly made his decision.
He was willing to offer his eyes to attempt this.
The close relative could only be him; it couldn't be someone else's Mangekyo. He had no objection to exchanging eyes with his son.
"Even if it fails, we can just swap the eyes back."
"This method carries little risk, and there are spare eyes in the Ninja World, so there's no need to worry."
Uchiha Tamahiko quickly reassured Fugaku.
He certainly wouldn't let Nagato's Rinnegan remain outside; he would obtain it and keep it safe.
This was to prevent Kaguya from being released. Dealing with Kaguya would be no simple task; it could potentially lead to the complete annihilation of the entire Ninja World.
However, since Uchiha Itachi had lost his eyesight due to his mission, he still had to take responsibility.
So, if he couldn't evolve to the Eternal Mangekyo, he would give one of Madara's Rinnegan to Itachi.
"Mm."
Fugaku breathed a sigh of relief, knowing his son could still be saved.
On the way back, Uchiha Tamahiko contacted the team working for the clan, telling them to stop chasing pirates and to purchase enough ships to accommodate all clan members for their departure.
He wasn't planning to stay in the first half of the Grand Line anymore; after all, their current location was a deserted island, and in half a year, they had only slightly improved the living environment, which was still far from suitable. For safety, Uchiha Tamahiko planned to take everyone with him when they left.
At the same time, he contacted Vinsmoke Judge, instructing him to prepare for the eye transplant surgery and to gather the necessary items.
Ten days later, they returned to the gathering point.
He sent Shisui to handle the ship purchasing, then Uchiha Tamahiko began to arrange for the clan members to prepare for their relocation.
Many items could be sealed in scrolls. Drinking water could be handled with Water Release, so the main thing was to bring plenty of fruits and essential supplies.
The preparations would take a few days, and during this time, the eye transplant surgery would be performed.
After waiting a few days.
"There won't be any problems with this surgery, will there?"
Uchiha Tamahiko looked at the excited Vinsmoke Judge and asked seriously.
After all, Mangekyo were truly hard to find, let alone suitable ones. Moreover, Itachi's Mangekyo could still be used by Sasuke in the future. If it were damaged, Sasuke might not even be able to awaken the Rinnegan.
"No problem, Lord Tamahiko."
"I have performed countless human surgeries and understand body structures very well."
"The structure of the Uchiha Clan's eyes doesn't differ much from ordinary people; the main difference is the bloodline. If, as you say, eye exchange can improve the purity of the bloodline, the success rate is definitely very high."
Vinsmoke Judge replied confidently.
He had operated on at least eight hundred, if not a thousand, people.
He had meticulously modified and perfected the clone soldiers to what he considered the most ideal state before beginning their production.
Being able to perform this eye transplant surgery, especially after Uchiha Tamahiko explained its reasons and importance, had him so excited he couldn't sleep for days.
During Uchiha Tamahiko's absence, new supplies had arrived from the Germa Kingdom, along with some instruments he needed, enough to complete the eye transplant surgery.
"Then let's begin."
Uchiha Tamahiko didn't say much more.
Such a madman would put 120% of his effort into doing what he loved best.
