Sylas didn't actually expect for Fanelei to start stripping after he said this. She turned around and pulled her robes down until something that Sylas had missed began to bloom into existence on her back.
There was a terrible gash in her side that obscured some of it, but the rest was clear enough for Sylas to tell that it was an incredibly intricate formation, one with six—no, seven nodes.
The seventh node was immature, not to mention ruined by the gash, but it was there.
Fanelei was trying some immature form of Rune Creation. But she couldn't quite control her Genes and the like, especially not at the A-tier. At best, she could probably manage up to the D-tier, and certainly not Legendary Genes.
So, instead, she tried a different method.
She physically moved the locations of her Aether Pathways and veins to etch a physical formation into herself. It was crude, especially crude. But it was the sort of thing that was quite impressive from a certain lens.
