"Emma, what do you think of this mask?"
Marvin handed the black Thousand Faces Mask to Yuniya, who, holding a mask bigger than her own head, studied it back and forth for a while before saying, "Dad, this mask isn't any different from ordinary ones, I mean, you can't tell anything from the outside when it's not activated."
Marvin was already used to such circumstances, whether it was the Divine Communication White Candle, the Star of Adam, or the Mermaid's Tear, the Truth Pocket Watch and other Divine Relics had excellent screening from the outside world, such that even a divine being like Yuniya was unable to detect their anomalies.
When you think about it, this wasn't strange at all.
If Divine Relics did not have a way to protect themselves and were discovered by other divine beings right away, how could the likes of Baji rely on these relics to return?
