Eighteen Heavenly Fiend Formation
Origin
Set up by Qing Yuanzi around his valley.
Effects & Usage
A series of eighteen interconnected fiendish formations surrounding the valley. They generate bloody fog, giant ghostly shadows, and冲天煞气 (soaring fiendish aura). The formations are interlinked; attacking one means facing the combined power of all eighteen. They must be broken simultaneously or one by one. Greatly increases in power when actively controlled by a cultivator.
