"Soulfall Valley" was an enormous natural rift deep within Soulbreak Cliff. The astral winds here were especially savage, forming countless tiny, ceaselessly spinning "wind vortices." Any cultivator caught within them would have their spiritual power torn apart by the raging winds, and might even have their divine soul swept away. Ordinarily, this was a deathtrap that even the cultivators of the Mulan Grassland rarely ventured into.
Yet now, the Heavenly South allied army had quietly spread a net from heaven to earth across dozens of miles around the rift.
Nangong Wan had personally led the Earth Division's core formation masters in a seven-day effort to fuse the Nine-Palace Lost Track Formation with the fragmentary ancient Heaven-and-Earth Reversal Formation that Han Li had obtained from the Burial God Abyss.
