The Spirit Snake Formation could not be considered an original creation of Su Chengyu; its foundation still lay in the Great Illusory Formation of Supreme Clarity.
It was simply that, based on the Spirit Snake Banner as the core, a series of adjustments were made, and all offensive and defensive aspects were constructed around the Spirit Snake Banner.
After the modifications, the range of the Spirit Snake Formation was much smaller compared to the Great Illusory Formation of Supreme Clarity, but the number of Magic Artifacts required was also significantly reduced.
In terms of offense and defense, it wasn't too much inferior to the Great Illusory Formation of Supreme Clarity, except that the closer one was to the Spirit Snake Banner, the more power the Formation could exert.
But for the current Snake Tribe, this kind of change in the Spirit Snake Formation was the most suitable.
