"There were no special traces visible to the Byakugan, nor were any objects left behind."
"Spatial perception revealed no traces of a Kamui-like space either. It could basically be confirmed that this was merely an ordinary ruin."
"They called it Kaguya Otsutsuki's palace, but she probably hadn't even lived here for more than a few days."
Uchiha Ensei stood alone, using the Byakugan's penetrating vision to carefully search every corner of the ruins.
A thousand years ago, Kaguya Otsutsuki had cast the Infinite Tsukuyomi, controlling every living being in this world.
Afterward, Kaguya Otsutsuki had treated the world as her own nursery, releasing the Infinite Tsukuyomi and freeing some of humanity, thus becoming the true ruler of the Ninja World.
As its ruler, even if Kaguya Otsutsuki had no need for it, her subordinates would still have given her the treatment she deserved.
Therefore, there should have been many things like Kaguya Otsutsuki's palaces from that era.
In the original story, Sasuke Uchiha had investigated many similar places, and at the last one, he had encountered Momoshiki Ōtsutsuki and his two companions when they came looking for him.
Before coming here, Uchiha Ensei had actually been worried that he might happen to run into members of the Ōtsutsuki Clan. With his current strength, he had no way to protect himself in such a situation.
But clearly, he had overthought it.
There was not even a trace of the Ōtsutsuki Clan, and there were few things left behind by Kaguya Otsutsuki either. Only a few scattered murals remained, all depicting events after Kaguya Otsutsuki's arrival.
Still, from Kaguya Otsutsuki's battle scenes, Uchiha Ensei had gained some understanding of what this world's most primitive power had looked like.
Judging from the murals alone, it had not seemed all that different from ninjutsu.
