The Palace of Equilibrium, the Lodge of Stored Awareness, the Aperture of Fierce Emotion, the Courtyard of the Heart Mirror?
Akaseki had barely read the opening before it felt familiar. Then it clicked: Tobirama Senju hadn't invented those ridiculous names after all. He must have found them in some ancient text!
Then Akaseki's expression turned strange.
Why did the opening of this so-called "Sharingan Ultimate Art" look so much like the Eight Gates Technique?
Akaseki remembered that Hell Yama King had said the Eight Gates Technique was a cultivation method created by Ashura.
But that thing was incomplete, and compared with the chakra-and-ninjutsu cultivation system, it was inferior by a mile!
And the Sage of Six Paths had just said that Ashura, who watched over Indra's descendants, had later refined the Sharingan Ultimate Art.
Seen that way, it wasn't surprising to find traces of the Eight Gates Technique in the Sharingan Ultimate Art. But—
As soon as Akaseki sensed the opening, he had a bad feeling!
After all, the Eight Gates Technique showed that Ashura's ability to devise cultivation systems was nothing special.
His skills were limited.
Fortunately, after sensing the rest in broad strokes, Akaseki understood the difference. Ashura wasn't simply trying to fob him off with the Eight Gates Technique!
Or rather—
Only the first two gates overlapped substantially with the Eight Gates Technique.
What came next wasn't a path that left the brain behind to develop the body further. Instead—
It used the unusual state of mind brought on by opening the Gate of Healing to strengthen emotion further. That was a perfect match for the Sharingan!
So it really was a Sharingan Ultimate Art. Without the Sharingan, strengthening emotion wouldn't accomplish much.
And for the Sharingan, this "strengthening" didn't merely stimulate chakra to change and evolve.
