Yin Qingxue murmured softly. After speaking, he scrutinized the six light gates before him anew and sank into thought.
Within the space encircled by the six light gates, the Former Tiandu Prefect Lord was puzzled for a moment. Energy rippled around him, and then his figure vanished into the light gate ahead.

"But using formation eyes to create another formation... such a method is simply unfathomable as gods and ghosts. Does that not mean this Two Forms Dust Array has no flaws
