This was simply not the kind of power a Middle Grade Spiritual Artifact could unleash!
Even a Top-Grade Spiritual Artifact couldn't compare to it.
As his life force continuously drained away, the Peak Foundation Establishment Demon was simply stunned.
For a moment, his brain seemed to shut down.
Why could a Middle Grade Spiritual Artifact display power far exceeding that of a Top-Grade Spiritual Artifact?
The next moment, a memory surfaced in his mind.
It was a memory of a conversation with another Inner Sect Disciple from his sect.
That Inner Sect Disciple was the grandson of the sect's Artifact Refining Elder. According to him, the Celestial Demon Sect, a Core Formation Influence, had come to their Black Dragon Hall to report something.
This report was about a Foundation Establishment Elder from the Celestial Cloud Sect who had been Refining Spiritual Artifacts specifically designed to counter them.
