Chen Yi knew the answer without needing to verify it.
He couldn't!
When Chen Yi had first studied the Sharingan, he had naturally known that an even higher-level Rinnegan existed beyond it.
However, by the time Chen Yi had been qualified to obtain a Rinnegan, he had no longer thought much of it.
Moreover, the Rinnegan was not cheap.
So he had never conducted an in-depth study of its principles.
Now, the First Councillor had given Chen Yi an entirely new perspective, along with a great deal of theoretical support.
Even without having researched the Rinnegan, Chen Yi could summarize things according to the First Councillor's theories.
Yin Release formed from spirit and Yang Release formed from vitality; the two were mutually rooted.
Using the eyes as a vessel, they could be used together.
But eyes formed through this method were still too low-level for Rank 7.
Rank 7 was a complete unity.
Essence, Qi, and Spirit fully merged as one, crossing over into reality.
Naturally, their eyes were the same.
Every Rank 7's eyes might appear to possess no special qualities.
That was because every Rank 7 basically fought only Rank 7 opponents, or even stronger foes.
Since this was standard for every enemy, no one noticed it.
But in the eyes of lower-ranked beings, Rank 7 eyes were absurdly powerful.
They could perceive principles, know what came before and after, and understand all things.
They could observe the laws of worlds great and small as clearly as palm lines.
They could catch enemies faster than the Speed of Light.
For Rank 7s, unless a Demon Eye reached Rainbow Level, it was less useful than an "ordinary" pair of eyes.
Rainbow Level Magic Eyes were special not because their underlying structure was superior to other Tier 7 eyes, but
