The Byakugan could evolve too?
Tobirama's eyes showed surprise. This was the first time he had heard of such a thing.
And from what Shin had just said, he seemed to know quite a bit about the Sharingan as well, even aware of the Mangekyō Sharingan.
No one in Tobirama's era should have awakened the Mangekyō Sharingan...
Tobirama's thoughts raced, and the image of Uchiha Clan Fugaku flashed through his mind.
He asked, "The Byakugan evolving... where did you learn that?"
Shin said, "It's the Kekkei Genkai of my own clan. Is it strange that I know about it?"
Tobirama pondered this. He had been Hokage for decades, and he knew very well the secret techniques and Kekkei Genkai of every clan in the village.
The Byakugan evolving... there had never been such an example, had there?
Or had it existed before Konoha's history, recorded only in the Hyuga Clan's ancient texts?
"Can you tell me more about the Byakugan's evolution?"
Shin shook his head. "I'm not very clear on it either. I only saw a few scattered mentions in the clan's ancient texts. I know nothing about the method of evolution or its power."
Tobirama felt a headache coming on. He had once researched the Sharingan, and he knew its method of evolution, but that was not something one could discover through research.
How was he supposed to begin and proceed with research when he was completely in the dark?
Judging from its depiction in the original work, the Tenseigan was not merely an eye manifested in a person's sockets. It could also be something like a weapon of war. The Otsutsuki Clan's civil war on the moon had made use of the Tenseigan's power.
A vast number of Byakugan, an exceptionally pure bloodline, and Otsutsuki Chakra—none of them
