The following days passed quickly.

Nial didn't get any sleep except on the last day, where he felt the need to sleep to wash away his tiredness.

He finished the engravings on the third Ancient Origin ring within days, which was much faster than one would usually require to engrave all the necessary runic constellations.

Nial's forte was runic constellations, which was why their engraving process wouldn't drag on his advancement in any way.

Now, the only thing he had to do to keep advancing was to absorb more mana, compress it and turn it into the fourth Origin ring's frame. The fourth Ancient Origin ring would be slightly more problematic than the third because there would be many Intermediate runic constellations he would have to engrave.
