Lu Xuan sighed softly, a White Jade Array Plate appearing in his hand.
With a thought, the Array Patterns on the Plate shifted, and the Thousand Barrier Xuan Crystal Array outside his cave abode altered accordingly.
At the outermost part of the formation, three transparent demon insects fluttered their wings at high speed, passing through a series of extremely cold ice mountains.
The transparent demon insects seemed to have an extraordinary intuition about the flow of Spiritual Power, always able to find the weakest spots in the formation and make difficult advances.
Suddenly, the ice mountains changed.
One after another, the mountains shifted, and cold air pervaded the entire heaven and earth, significantly slowing the speed of the three transparent demon insects.
Gentle snowflakes seemed as light as nothingness, slowly falling, and a barely visible layer of frost began to form on the bodies of the transparent demon insects.
