After twelve crisp sounds, twelve milky-white Dan medicines were lifted out of the furnace by Ning Cheng and fell into the jade box beside him. Ning Cheng picked out one of the Dan medicines and looked at it carefully; it was pure milky white, without any impurities at all, exactly the appearance of a top-grade Xuan Ni Dan.
Ning Cheng sighed in relief. The difficulty of refining Xuan Ni Dan was no less than that of Xuan Ming Dan. Being able to refine such high-quality top-grade Xuan Ni Dan without using any Dan formulas meant that he could also refine Xuan Ming Dan.
Ning Cheng had only one set of the materials for Xuan Ming Dan, and he dared not refine it casually. If something went wrong, it would be a disaster. Who knew how long he would have to stay in Rule Road, or whether there would be ingredients for making Xuan Ming Dan in there?
