After saying that, Orochimaru took out a scroll from a hidden Sealing Barrier and handed it to Sarutobi Toru.
Sarutobi Toru was slightly startled. He had not expected Orochimaru to have gone this far.
In truth, the Byakugan was far less corrosive than the Sharingan, so research into the Byakugan and Shikotsumyaku should have been relatively simpler. One could see that from the fact that the Byakugan still required the protection of the Caged Bird Seal.
Why did the Sharingan not need any protection? It was simple. For ordinary shinobi, the Sharingan's burden was simply too great, and its corrosiveness too strong. After transplantation, their combat power often fell rather than rose, and some were even drained to death alive.
Wasn't even a genius like Hatake Kakashi turned into a famously weak-kidneyed man after receiving a Sharingan transplant?
When Kakashi was twelve or thirteen, two Chidori left him out of Chakra. When he was twenty-seven or twenty-eight, two Chidori still left him out of Chakra. One had to know that, based on the normal growth of a shinobi's Chakra, twenty-seven- or twenty-eight-year-old Hatake Kakashi should have possessed at least five times the Chakra he had at thirteen. This showed just how heavy the burden of that one Sharingan was.
But no matter how simple this research might have been, it was still a genetic analysis map of the entire Otsutsuki Clan. Even an incomplete version was extremely rare.
Sarutobi Toru gave Orochimaru a deep look. Being able to create this kind of genetic analysis map meant that Orochimaru had definitely laid hands on the Hyuga Clan.
But considering Orochimaru's personality, targeting the Hyuga Clan was practically only natural. And now that he was the leader of Root, doing such a thing was even easier.
Besides the Hyuga Clan, Orochimaru should
