Nether Abyss Valley, valley floor.
The second segment of the Segmented Purification Array had been severed. The Spirit-Transforming Demon Orb hung in the center of the severed section, slowly rotating as it reversed the demonic qi into spirit qi bit by bit and fed it into the Earth Vein.
Li Yuan withdrew the spirit power sustaining the array and swept the entire valley with Spatial Investigation Technique at the Perfection level.
The Six-Point Resonant Sealing Array was operating normally, and the six Array Eye Spirit Stones bore stable loads. The newly established Spatial Lockdown Array used the Null-Pattern World-Suppressing Disk as its Array Eye, locking down the spatial structure around the rift. Although the Starlock Devil-Sealing Mark had loosened somewhat, the active resistance supported by the Spatial Restriction Technique at Major Accomplishment kept it from worsening for the time being.
The Segmented Purification Array had already cut off two sections of the main Dark Vein, a total of twenty zhang. Once the demonic qi supply was cut off, the concentration of demonic qi around the rift began to decline slowly.
Yet the rift itself had not shrunk.
Myriad Image Retrospection brought up the rift's spatial structure. Compared with records from several months ago, the spatial walls along its edges were still thinning, now less than sixty percent of their former thickness. The rate of thinning had nothing to do with demonic qi concentration; the spatial structures at both ends of the rift were drawing closer on their own.
Li Yuan calculated for a moment. At the current rate, even without an external impact from Spirit Transformation Devils, the rift would expand within roughly two months to a width capable of allowing Nascent Soul Cultivators through. If the Spirit Transformation Devils forcibly propped it open with the Netherdemon Blood Sacrifice Array,
