Xiang Wentian asked in a deep voice, "Brother Nangong, why are you so excited?"
"Brother Xiang, you don't know, one of the very important factors that restrict alchemists is the purification of medicinal materials! The faster the Alchemy Furnace heats up, the more thorough the purification will be!
If the Alchemy Furnace heats up too slowly, some other changes will occur when the medicinal materials liquefy."
Xiang Wentian suddenly realized, turned his head to Qin Yu, and asked, "Qin Yu, how can we speed up the heating? Stop beating around the bush!"
"It's quite simple, you just need to purify the Earth Fire," Qin Yu said with a slight smile.
"Purify the Earth Fire?" Nangong Wudi was utterly confused.
Wu You rolled her eyes. This Mr. Qin, how could he say anything? How can Earth Fire be purified? Isn't that a joke?
"Mr. Qin, don't try to create a spectacle! Do you even know what Earth Fire is? How can Earth Fire be purified? You really speak nonsense!"
