Li Fan initially harbored some doubts, wondering if the object tucked up his sleeve was secretly causing trouble, but one after another, five or six streams of demonic aura appeared within the range of his Divine Sense. He could then confidently conclude that this was no coincidence; Divine Teachings had launched a large-scale operation.
To know that Cloud Dream Marsh spanned a thousand miles with even more intricate channels beneath the marshland, just within the reach of Li Fan's Divine Sense, so many demons had broken out of their seals. It's likely that there were even more in other areas.

If a few escaped and caused major trouble, who would bear the responsibility for failing to guard the demons?
