After seven years of hard work, Nial finally reached the Prometheus rank.
Without focusing on the cultivation process, it was quite arduous to create the remaining eight Ancient-grade Origin rings.
However, he knew what he was doing even though it looked like he was the first to create Ancient-grade Origin rings. If others were to know about it, they would probably bombard him with questions. Fortunately, that was never a problem because not even the matriarch of the Silver Eye Clan knew what a Royal-grade Origin ring should look like.
Whether it was a special perk of Unique Origin rings or the grade of the matriarch's Silver Eyes didn't really matter. Important was only that the matriarch couldn't see the secrets behind Unique Origin rings. It was as if the Origin Rings didn't have a grade in the first place.
That was what Ayase used as an indicator of someone creating Unique-grade Origin rings.
