The area of Immortal Mountain Island is much larger than Wind-Fire Island, and the island originally had three defense lines. The one led by Tianchenzi and arranged by Li An and others is the newly added fourth defense line!
The Dao Sect, which destroyed the Demon Sect back then, had seized many of the sect's treasures. Now, they have taken everything out, including some very high-level Demon Bones and materials, and have arranged them according to the Array of Transformation meticulously thought out by the upper echelons of the Dao Sect.
This process was quite lengthy, and due to the multitude of matters, Tianchenzi could not oversee it every day.
Li An kept waiting and finally found an opportunity. On this day, while embedding various materials into the formation eyes, he quietly took out a corpse of an Exotic Spirit, which had already been refined so the ominous aura was internalized and not released. Otherwise, he would have had to go through a lot more trouble.
