A drop of sweat came down the side of Yu Huan's face, her focused gaze reflecting the Alchemy Furnace, the light green Earth Flame billowing around it.
She was using a furnace they bought in the Emerald Falls City.
Being a high-level 2nd-tier treasure, it was better in principle than the 1st-tier furnace they got from Gu Zhen.
But the latter was a top-class artifact used as the main treasure of the Alchemy Branch.
Not just any Profound Grade Treasure could become one, even for Boundless Mortal World.
It had to have unique properties, and exceptional quality that went beyond just the level, tier and grade classification, even if the classification held back its usefulness to Wu Long and Yu Huan at this point.
The former, on the other hand, was a far more common treasure. Even though Wu Long did choose a better quality one out of everything that was available at the time, it still fell short of the previous one.
That, however, did not mean they settled for a worse option.
