"The Yin-Yang Bagua Defense Formation?!"
Summer frowned slightly and gently tapped the manual, bringing up the detailed description of the formation.
It was a defensive formation based on the Tai Chi Yin-Yang Bagua. As the saying goes, the Tao produces one, one produces two, two produces three, and three produces all things. The formation could absorb the energy of heaven and earth to form a transparent protective barrier. As long as the core was not destroyed, the grand array could carry out automated defense and repair indefinitely. As long as heaven and earth endured, the formation would never fail.
