Su Bai did not immediately respond to the face's plea.
Instead, his calm gaze swept across the interior of the great hall. Then he raised his left hand and casually traced a few strokes through the air.
Where his fingertips passed, strands of pale silver spatial runes and isolation array patterns, thin as hairs yet profoundly mysterious, formed from nothing. They rapidly spread and intertwined into an invisible film of light, silently enveloping the deepest area of the entire hall.
The light film flickered faintly, then vanished completely into the air.
This was a simple yet highly effective spatial isolation and information-blocking array.
