The Spirit Refining Furnace was originally used to fuse various magical artifacts, enhancing their ranking.
Zhou Dao's Thunderfire Wings and Black Dragon Sword were both born through the fusion of many magical artifacts in the Spirit Refining Furnace.
Hum...
With a wave of Zhou Dao's hand, the Spirit Refining Furnace emerged, spouting bright yellow flames that emanated an intense heat.
"I just don't know if this treasure can nurture a spiritual tool."
Zhou Dao was apprehensive, but he still decided to try it. He activated his true qi and cast the White Snake Sword and Black Dragon Sword into the Spirit Refining Furnace.
Rumble...
Two rays of sword light crisscrossed in mid-air, resembling a white python turning its head and a black dragon sweeping its tail, they both drilled into the Spirit Refining Furnace.
