The Ghost Witch Sect was located deep in the mountain and they have constructed their fort in a chokepoint of the mountain path. The road past the fort's gate was a narrow winding path that was flanked by sheer drops on both sides. The meandering path would eventually lead to the top of the mountain where the headquarter of the sect was.
Looking up from the foot of the mountain, the hillside was dotted with small clusters of houses. There must be thousands of people living behind the high walls. At the very top was a large stone structure.
That's the headquarters.
"Immortal Master Chen, on your mark."
Perfected Cultivator Shi bowed and said.
"Now."
Hearing Chen Fan's command the dead army formed six units and swarmed toward the top of the mountain.
The path was treacherous and the cliffs deadly, but none of that could have stopped the spell casters and the Internal Force users.
