Lu Qing's Primordial Spirit rapidly expanded, seeming like a sky-reaching giant within the space of the forehead acupoint, almost shattering the space.
But in the next moment, under the operation of the cultivation technique, the Primordial Spirit began to contract swiftly, compressing incessantly, nearly turning into a single point.
The endlessly shrinking Primordial Spirit, with its terrifying power, directly caused the entire space of the forehead acupoint to tremble.
As the entire space seemed about to collapse, following the point formed by the Primordial Spirit, the Primordial Spirit once again slowly expanded, transforming back into a sky-reaching giant.
Just like that, Lu Qing's Primordial Spirit continued to expand and contract within the forehead acupoint.
Each time it expanded and contracted, Lu Qing utilized the spell he had deduced to compress and refine the Primordial Spirit in unique ways.
