Gaia's Blessing
Even though she made it sound easy, the construction of an anchor that can produce divine energy was far from easy. Even now, the only reason she even had an anchor that could do that was due to it being her main anchor, one that represented her participation in this event.
If her anchor is destroyed, she'll be disqualified. While she may not be dead, she wouldn't be able to win either.
A slow descent to destruction.
Shaking her head free of the negative thoughts, Shiro tried to finish the anchor.
The main thing that was different when she was making her own anchor was that back then she had forcefully raised her level to the realm of gods and used tier 7 magic circle to build her anchor. While she may not have access to that, she now understood how to use their runes.
If combined properly, it was akin to a tier 8 magic circle.
