Silvermoon shook his head and laughed. "It's not that I'm formidable; it's that there are only a few people at Mount Innerherat who have trained in the [Eight-Nine Arcane Art]. By process of elimination, I was able to guess that it was you, junior apprentice-brother."
Ning nodded. The [Eight-Nine Arcane Art] was located in the Three Realms Palace; only personal disciples and those who had received special permission from the Old Patriarch could learn it.
"If you transformed into someone else, I might not have been able to tell that it was you," Silvermoon said with a laugh. "These 'seventy-two transformations' cause a person's aura to completely change; even the appearance of sin or karmic merit surrounding you changes. This truly is an incredible transformation divine ability."
