Gu Shi Yi was here waiting for the person who set up the Formation to come and collect the Evil Spirits; the Wind-following Grass within the Formation had been enchanted by a Taoist nun, its energy growing stronger day by day. When the time was almost right, the Taoist nun made the Wind-following Grass thrash about within the Formation, pretending that the Evil Spirits had gained considerable force and wanted to break through the great array. This triggered the Prohibition within the Formation. When the person who set up the Formation sensed it, they would likely come over in the next two days.
