Gu Jinlai thought of the True Spirit Manifestation Method derived from the Perfection of the Grand Sun Nine Refinement Visualization Method.
Not long ago, when the Heavenly Sword Missile was introduced, he had considered using the True Spirit Manifestation Method to manually guide them by attaching to the missiles.
However, during a missile explosion, there would inevitably be a violent impact that could harm the True Spirit.
If he really did so, the precision and hit rate would greatly increase, but each missile explosion would at least require him to waste a Qingguang to recover the True Spirit.
Otherwise, if half of his True Spirit was gone in an instant, a single misstep could even damage his foundation.
It was like a person who had lost half their life; even if they could be saved, there would inevitably be hidden dangers.
But this True Spirit Projection Technique gave Gu Jinlai hope.
