When the token came in contact with the pillar, white glyphs appeared from the base of the pillar and extended to the mirage bubble whose glyphs radiated with a soft gentle glow before the mirage finally popped like a bubble.
The anti-climatic display would mislead one into thinking the defense of the mirage bubble was weak, but Yang Qing knew it could defend against any measure that a middle-stage domain expert could think of.
The ward surrounding the pillars was part of the array that surrounded the entire floor which was the Kirin Guardian Veil Ward. It was a protection ward that not only protected the entire floor from being breached but it isolated the room from most searching means either by domain sense, karmic deduction, or artifacts with similar use.
Without the token, Yang Qing would not be able to even know of the existence of the floor.
