Looking at the towering Profound Light Crystal Stone before him, Qin Fengming's eyes revealed shock, but even more so, an expression of joy that flashed incessantly.
Putting aside whether this Profound Light Crystal Stone could be refined into a magic treasure, even its ordinary use—enhancing a magic treasure's sharpness alone—was enough to drive cultivators mad.
If the Four Symbols Pure Radiance Sword were enhanced with the Profound Light Crystal Stone, the sharpness of those five blades could certainly be raised another level.
When the Four Symbols Pure Radiance Sword Array was deployed after being imbued with the Profound Light, to what degree its attacking might would reach filled Qin Fengming with anticipation.
With a wave of his hand, Qin Fengming put away the Cold Light Sword and sat cross-legged before the enormous crystal.
After making some slight adjustments, he raised a hand. A strand of silk flashed into existence and shot toward the enormous Profound Light Crystal Stone before him.
With a push of divine sense, the emerald strand transformed into a three- to four-foot-long thread and began slowly cutting into the enormous crystal.
