"According to the information you gave me, Mangekyo can cause blindness to its user because of the complete exhaustion of the eye. The Mangekyo don't have the self-healing ability, but the Eternal Mangekyo is different. It could automatically recover its conditions, so the burden the Sharingan caused to its user's body will be reduced a lot."
"In other words, as long as your body can bear the burden from the use of the Mangekyo Sharingan, then half of the problem is solved. As for the risk of blindness, you have to take good care of your eyes' condition. As long as you use it carefully and take good care of your eyes condition, you won't go blind from using the Mangekyo."
Bulma was silent for a while, maybe she was organizing her words, and after a while, she spoke.
"That's just in theory. Even if I take good care of my eyes, I won't be blind. But that is not the root of the problem. Even if I can obtain the Sharingan's power, the only ones in this world who have the Mangekyo is the Itachi."
"The Eternal Mangekyo is not something that the current me can obtain. Even if I can get the power of Itachi's eye, I can only use it for a little longer at most. In the end, there is nothing I can do."
Ryoha said with a bit of frustration. He believed in his Sharingan because both Bulma and Kyubi said that his Sharingan was the best and had 100% compatibility with his body. Therefore, Ryoha was not afraid that he would not be able to awaken the Mangekyo. He was afraid that he would become blind after using it.
"Actually, there might be another way. Although it is a bit difficult, I think it is feasible. The Uchiha's ancestor, Indra, obtained the Mangekyo with his strength. However, his brother has the body of an immortal. In other words, he couldn't take his brother's eyes to fulfill the condition for obtaining the Eternal Mangekyo. So how did he do it? I have been thinking about this question all along."
"But later, I thought that if the power of the Sharingan represents death, then the power of Wood Release should represent life, can the Wood Release use its power to relieve the side-effects of the Mangekyo?"
"Since the Sharingan and the Nine-tails chakra were related, then it was even more direct. The abilities of the two brothers came directly from the Sage of Six Paths."
"In other words, if the Sage of Six Paths could grasp these two powers at the same time, then the power of the Eyes of Indra and the Body of Ashura should be able to be combined, and at the same time, make up for their shortcomings. The healing power of Wood Release's strong vitality might be helpful to the Mangekyo Sharingan." Bulma said.
"Bulma, I think I understand what you mean. The body of the 1st Hokage is so precious, and it contains the mystery of Wood Release. Before the mystery is solved, Konoha's rotten higher-ups would never destroy the body. It should have been well-preserved somewhere for many years."
"You mean by obtaining Senju Hashirama's body, you could extract his genes, so we could fuse the Wood Release genes and the Sharingan genes.. and maybe we could create a completely new type of Sharingan that will be different from the Eternal Mangekyo Sharingan."
"Maybe the two would complement each other, so the eye power consumed by the Mangekyo Sharingan could be replenished automatically due to Wood Release's ability, and the Mangekyo Sharingan might evolve further after resonating with the Wood Release chakra. Do you mean that? Ryoha became more and more excited as he spoke.
This was because he also felt that this idea might really come true. Uchiha Shisui's Kotoamatsukami benefitted greatly from Hashirama's cells*. Danzo had also relied on those cells to be able to control a large number of Sharingans on his arm.
The power of the Sharingan was too wicked. It actually did some invisible damage to the user's body and soul. Otherwise, the burden of its usage on the body wouldn't be so great, and the Mangekyo Sharingan would not cause blindness.
But Wood Release's power was the opposite. It was full of life force and vitality. These two existences were the polar opposite of each other, but could also complement each other well.
"That's right, but here's the problem. All these years, I have been researching how to make two types of Bloodline Limit blend together without conflicting with each other. If it's an ordinary Bloodline Limit, I can now let your body have two types at the same time."
Bulma's words made Ryoha almost cry out in excitement. Good heavens, having two types of Bloodline Limit. If Bulma continued her research, wouldn't he be able to have all Bloodline Limits in the entire ninja world?
"Don't be happy just yet, I'm just talking about ordinary Bloodline Limit. Although in theory, the power of the Sharingan and the Wood Release can complement each other since the life force provided by the Wood Release could nurture the Sharingan further and prevent damage from its usage.."
"We still have some problems here. From ancient times until now, only the Sage of Six Paths could truly grasp and combine these two powers at the same time, because the two rejected each other very strongly."
"With the technology, I have now, even if I can fuse the Wood Release and the Sharingan, the rejection between them will likely destroy your genes. At that time, you will undoubtedly die. What I lack now is not the technology to fuse two types of Bloodline Limit, but how to prevent rejection of the two Bloodline Limits from causing any danger in the fusion process. In other words, I lack the technology that can ensure the safety of the fusion process of the two powers." Bulma sighed and said with a bit of disappointment.
"Hehe, Bulma, in fact, we are all too radical. Everything will be alright. Back then, we never thought that we would obtain the Bloodline Limit. But now, we have one. Moreover, I have not awakened the Mangekyo yet. You still have the time to study it. Perhaps you will find a way at the last moments of my eyes."
"And, didn't you tell me that there is no free lunch in this world? If one possessed the Wood Release and the Sharingan at the same time, then it is indeed a miracle. If there is no risk to obtaining them, then after all these years, there will be people besides the Sage who have completely mastered them. So if you really can't do anything about it at that time. I can only give my all."
A trace of madness flashed through Ryoha's eyes. The battle with Orochimaru before made Ryoha know what he had to pay if he wanted to obtain something. He was really worried about failing and dying. But not only did he complete the Raikiri, but he also awakened the third tomoe. The greater the risk, the greater the benefits he could obtain. It was just like venture capital.
So Ryoha decided that if it really came to that time, he would rather die than be an ordinary blind guy.
In this world, it was better to die than just be an ordinary person. He couldn't even protect the people he cared about. He couldn't even guarantee a stable and comfortable life. Living was more painful than dying, so why not just give it a try?
*TL Note: The Kotoamatsukami required at least a decade before it could be used again, but this period can be drastically reduced through Hashirama's cell powers.
