In fact, when it comes to engraving the fourth magic rune, the best candidate isn't Zhao Guang, but other Legendary Mages with expertise in the Thunder Attribute rules. Unfortunately, Zhao Guang doesn't know any Mage of that level.

His subordinates not only include the Thunder Warriors but also various other professionals.
Upon completion of the engraving, Scola was immediately surrounded by lightning, completely out of control. The entire chamber crackled with thunder and lightning, and if it weren't for the magical barrier around them, the commotion would have long been discovered.
Zhao Guang used his spiritual power to suppress and control the Thunder Power in Scola.
It's undeniable that Scola's talent isn't particularly great, especially in terms of Magic talent.
