Although the broken sword's attributes differed from those of the Hundred Treasures River, both were treasures of Spirit Transformation disciples and contained incomplete Spirit Transformation true intent. Thus, refining it would still bring the Hundred Treasures River considerable benefits.
As for the other two pieces of treasure iron, although they contained no true intent of Spirit Transformation disciples, they were genuine quasi fifth rank water-attribute treasure iron. They would likewise benefit the Hundred Treasures River, which shared their water attribute.
That was precisely why, after Ling Pengyun had escaped disaster and returned to Demon Island, he had ordered the severely damaged Hundred Treasures River to begin refining these three objects.
Ordinary magical artifacts would have struggled to accomplish this, but the Hundred Treasures River was of an exceptionally high grade and had long since developed intelligence. Naturally, it could refine spiritual objects just as a cultivator could. It could even draw upon spirit energy to temper and improve itself.
Given its current condition, if it had several tens of thousands of years, it might well have a chance of advancing from fourth rank superior grade to quasi fifth rank through its own efforts alone.
Of course, that was clearly impossible. As a spirit treasure, how could it go unused? Moreover, once it took part in battle, it would inevitably suffer damage, perhaps even severe damage.
However, spirit treasures generally refined spiritual objects to strengthen themselves very slowly. Even the Hundred Treasures River, which possessed a Spirit Transformation disciple's spirit treasure, was no exception. Besides, the three objects it was currently refining were all extraordinary.
Thus, by Ling Pengyun's estimate, relying solely on the Hundred Treasures River to refine those three objects would probably take several hundred years before it finished.
Ling Pengyun could not wait that long.
There were, however,
