"That's right." Uchiha Yasuo nodded calmly.
"The two great noble clans of Konohagakure, in fact their ancestors were both descendants of the Ōtsutsuki clan."
"The ancestor of the Uchiha clan was Ōtsutsuki Hagoromo, the Sage of Six Paths, and the ancestor of the Hyūga clan was Ōtsutsuki Hamura."
"The Hyūga clan was originally extremely dominant. They only needed to fuse together the eyes of a large number of clan members, and they could naturally synthesize the 'Tenseigan', but precisely because it was too easy, it often led to internal strife within the clan."
"So, in order to avoid such tragedies from happening frequently, the Hyūga clan developed the 'Caged Bird' seal to prevent clan members from having their eyes taken by force."
"But if they were truly to face the danger of extermination, the Hyūga clan's main family could in turn use the 'Caged Bird' to force the branch family members to offer up their eyes, thereby in one stroke synthesizing the 'Tenseigan' to turn the tide and resolve the crisis."
"This 'Tenseigan' is extremely powerful, and it has no side effects. It is one level higher than an ordinary Mangekyō Sharingan, a powerful eye that can be compared with the Eternal Mangekyō Sharingan. Even when compared to the 'Rinnegan', it is not much inferior."
"Otherwise, what do you think the Hyūga clan relies on to be spoken of together with the Uchiha clan as the two great noble clans?"
"Just relying on that lousy Gentle Fist of theirs?"
"So that's how it is!" Orochimaru nodded thoughtfully, completely believing Uchiha Yasuo's words.
"So, Orochimaru-sama, my goal really is as you said, but as for the method of synthesizing the 'Tenseigan', I did not lie to you. You will know once you go and try it."
"The problem now lies in that I do not have a way to undo the 'Caged Bird' curse mark, and without breaking the 'Caged Bird' curse mark, relying only on that small number of Byakugan from the Hyūga main family is not enough to synthesize the 'Tenseigan'."
"Hehe..." Orochimaru greedily licked his lips and laughed. "This problem is actually not difficult to solve."
"Although I also do not have a method here to undo the 'Caged Bird' curse mark, the Hyūga main family definitely does!"
"As long as I know of the existence of this thing, I naturally have a way to obtain it."
"Rest assured, after I obtain it, I will also share a copy with you."
"That will not be necessary." Uchiha Yasuo refused directly. "The evolution path of my eyes in the future is the 'Rinnegan', just like the one in Leader Pain's eyes. The 'Tenseigan' is not suitable for me."
"Is that so?" Orochimaru nodded in satisfaction, his sense of the credibility of Uchiha Yasuo's words once again increasing by quite a bit.
"Can the Mangekyō Sharingan also evolve into the Rinnegan?"
"This is quite an incredible piece of information."
"However, in that case, your goal and Pain's will be in conflict."
"Pain wants to capture the tailed beasts and revive the Ten-Tails. I imagine it is also so that he can let the Rinnegan and the Ten-Tails' jinchūriki combine and achieve the Sage of Six Paths' technique of immortality."
"If he wants to overawe the shinobi world and bring eternal peace to it, this matter of immortality is absolutely indispensable. Otherwise, once he dies, his rule will end with him, and after his death war will descend once again."
"But there is only one Ten-Tails. Which of you should it belong to?"
"This really is a very hard question to decide, isn't it!"
"Hehe..."
Orochimaru did not conceal at all his malice-filled smile, and looked at Uchiha Yasuo with a playful gaze.
"Yasuo, I can see that you are a very ambitious person; you absolutely will not give up the Ten-Tails."
"In other words, you already have a method to deal with Pain, right?"
"That makes sense. Your Mangekyō Sharingan possesses the ability of 'prophecy', able to see many things in the future, so no doubt you are thoroughly familiar with the information on Pain, right?"
"That is not something you need to worry about, Orochimaru-sama." Uchiha Yasuo shrugged indifferently.
Orochimaru's pair of snake-like vertical pupils stared fixedly at Uchiha Yasuo's face, carefully scrutinizing him for quite a while. Seeing that he still had an indifferent expression, he flicked his long tongue, licked his lips, and then laughed again.
"Tsk, tsk, this 'prophecy' ability really is unreasonable!"
"Forget it, this is a matter between the two of you and has nothing to do with me."
Seeing that his probing had come to nothing, Orochimaru no longer made idle chatter and sat back down in his original seat again.
"Then now, can we talk about the matter of the payment?" Uchiha Yasuo asked with a smile.
"Of course!"
Orochimaru nodded and spoke very generously: "Yasuo, go ahead and say it. What do you want to obtain from me?"
"Your information is very valuable. As long as it is something I can provide, I definitely will not refuse."
"Haha..." Uchiha Yasuo raised his head and laughed. "Orochimaru-sama really is straightforward, then I will not stand on ceremony."
"I need you to help me transplant Hashirama's cells."
"I also need the technique of Impure World Reincarnation, and you have to help me carry out some targeted modifications and optimizations."
"I also need the training method of the Snake Sage Technique. You have to help introduce me to the sages of Ryūchi Cave."
"I also need..."
Uchiha Yasuo named an exorbitant price, rattling off a whole string of requests, and Orochimaru listened in silence. In the end he nodded very straightforwardly and said: "All right, I can agree to all these conditions. There are some things I can give you right now, but for some things I still need some preparation time."
"No problem!" Uchiha Yasuo was also very straightforward.
A moment later, Uchiha Yasuo walked out from Orochimaru's room fully satisfied.
In fact, he himself did not know whether the 'Caged Bird' curse mark truly had a method of release, but it did not matter. As long as Orochimaru believed that such a method existed, that was enough.
As for Orochimaru not being able to obtain the method of undoing the curse mark from Hyūga Hiashi or other members of the main family, that could only mean that the Hyūga main family was too tight-lipped, refusing to hand it over even in death. One could not blame Uchiha Yasuo for that.
Orochimaru was also very satisfied.
Besides learning from Uchiha Yasuo about the 'Tenseigan', this 'technique of immortality', he also learned much information about his own future.
For example, the development of the curse mark!
Right now, regarding the development of curse marks he only had a prototype, but Uchiha Yasuo told him that in the future, through research, he would turn the curse mark into another kind of 'immortality technique', and even use this method to revive after death.
This made him even more interested in the curse mark and determined that he would invest more time in it from now on.
When researching this sort of thing, what is lacking most of the time is direction.
Very often, most research wastes an enormous amount of time and effort, only to reach the conclusion that this path leads nowhere!
But Uchiha Yasuo could tell him, having seen which ninjutsu he would successfully develop in the future, and which he had never seen at all.
Based on this information, Orochimaru could naturally adjust the direction of his future research and development accordingly, avoiding wasted time and effort.
However, Uchiha Yasuo had not told him about the 'Kāma', for after all, the 'Kāma' was also a 'technique of immortality'. If Orochimaru were to learn of it and instead spend time studying the 'Kāma' without going to massacre the Hyūga clan, that would not be good.
Holding the benefits he had obtained from Orochimaru, Uchiha Yasuo had only just returned to his room when the corner of his eye caught sight of a black-and-white shadow emerging from beneath the ground.
"Uchiha Yasuo…"
Before Zetsu could finish speaking, Uchiha Yasuo asked with a cheerful smile: "Hey, Black Zetsu, do you want to save your mother?"
"I can help you!"
