"Huh? What's wrong?" Ryker asked. His cultivation knowledge was still rather shallow, so he didn't know if Long Meiling had noticed a flaw in his Golden Core or not.
"Ryker, you… how did you manage to form a supreme-grade Golden Core?"
In contrast to his worries, however, Long Meiling's frown slowly turned into a beaming smile. Supreme-grade!
Regarding the quality of one's Golden Core, there were 4 grades to speak of: Low, average, superior, and supreme.
There was no need to talk about a low quality Golden Core; if this was the case, one could forget about reaching Soul Wandering unless some sort of miracle were to occur.
An average quality was something of a baseline. Usually, unless one also suffered from a poor spiritual root, an average quality Golden Core was enough for about a 50/50 chance of achieving the Soul Wandering realm in your lifetime.
