"Should I open it?" Hinata hesitated for a moment, then stepped forward under Naruto's encouraging gaze and pushed open the great door engraved with mysterious patterns.
Beyond the door, a giant golden eyeball floated in midair.
Tobirama raised an eyebrow, and the urge to study it instantly welled up in him.
"This is our Ōtsutsuki Clan's Tenseigan." Shuo gazed at the eye shimmering with golden light, feeling somewhat wistful.
It had been constructed from the Byakugan left behind by countless ancestors.
Listening to Shuo's introduction, Tobirama's mind filled with all sorts of strange ideas.
Since piling a large number of Byakugan together could form a Giant Tenseigan...
Then couldn't the Hyuga Clan in Konoha use a similar method to create a Giant Tenseigan of our own?
To take it a step further, if it worked with the Byakugan, then the Sharingan should work too.
If we put a whole pile of Sharingan together, would we end up with a giant Sharingan?
No, it should undergo atavism or evolution.
Then... a pile of three-tomoe Sharingan could produce a giant Mangekyō Sharingan, and a pile of Mangekyō could produce a giant Rinnegan.
What a shame.
A trace of helplessness flashed through Tobirama's eyes. He really had wanted to gather a whole pile of Mangekyō and make a giant Rinnegan just now.
But the Uchiha did not currently have that many Mangekyō for him to use.
From what Shuo had said, the Giant Tenseigan must have used many Byakugan. Calculating by volume, it would have required at least close to a hundred.
And the Uchiha did not have nearly a hundred Mangekyō for Tobirama to work with.
Forget Mangekyō-the Uchiha could not even provide a hundred three-tomoe Sharingan.
If they really had a hundred Mangekyō, those lunatic Uchiha would probably tear a hole
