"It would be best if I could find the materials that can refine Precious Treasure Artifacts into Immortal-grade Treasures,"
thought Ling Xiao to himself.
The reason he hadn't yet upgraded his several treasured swords to Immortal-grade Treasures was not for lack of willingness, but rather because he hadn't yet gathered all the necessary materials.
Merely having Immortal-grade Treasures as materials was not enough; he also needed a very special material—a Fusion Stone.
Fusion Stones were extremely valuable, and even the lowest grade ones were worth a fortune, making them almost impossible to purchase.
However, the True Demon Forbidden Land, as a site of the former True Demon Empire, had a very high chance of containing Fusion Stones.
With a single low-grade Fusion Stone, combined with an Immortal-grade Treasure, Ling Xiao could upgrade one of his treasured swords from a Precious Treasure Artifact to an Immortal-grade Treasure.
