Shen Jiaojiao, the young master of Wanhun Hall, was ordered by the hall master to lurk in the immortal sect, and went to the West with the Nine Spirits Immortal Lord to exchange and study. She discovered that in the West, soul-eating demons were regarded as extremely evil after only killing a hundred people in their lifetime, while in the East, it was normal for demon cultivators to massacre cities and refine souls. Taking advantage of the mutual suspicion between the Immortal Sect and the magician, Shen Jiaojiao released the soul-eating demon, bloodbathed City A to refine the human elixir, and used the Ten Thousand Soul Banner to contain the archangel, forcing the Nine Spirit Immortal Lord to leave with everyone. In the end, the demonic cultivators occupied the west and ruled separately from the immortal sect, while the western soul-eating demon could only follow behind her and offer his soul tremblingly.
