The Swift Wind Wings was originally just a top-tier spiritual artifact.
After Fang Hong advanced to the Divine Transformation Stage, its effect on speed enhancement became less obvious, even struggling to keep up with Fang Hong's pace.
However, some time ago, Fang Hong tried to refine the three white feathers he obtained from the palace into the Swift Wind Wings, and unexpectedly, it brought about an unforeseen effect.
The grade of the Swift Wind Wings soared dramatically, directly crossing a major grade and reaching the level of a high-grade spiritual treasure.
Such astonishing advancement speed even startled Fang Hong himself.
This couldn't help but make Fang Hong secretly wonder, could these three feathers left by Thunder Venerable be the feathers of some Divine Beast?
