When Ian removed the gauntlet covering his entire left arm and elbow, a pale cyan glow suddenly lit up, like a bright moon rising in the dim quiet room, illuminating the faces of both individuals.
The youth's left arm had turned crystalline but didn't look ferocious; instead, it possessed a unique beauty, as though an artist had meticulously sculpted an arm out of crystal. The sparkling cyan crystal lattices patterned within it shimmered with light, revealing every muscle and blood vessel in the arm with striking clarity.
Even Elder Mantle, who had long steeled himself for this, couldn't help but tremble slightly upon witnessing the arm, nearly gasping in awe.
But he quickly regained his composure, shook his head, and then asked Ian in a voice he forced to be calm, "May I... take a closer look?"
"Please do."
