Just as Qing Feng was hesitating about Ding Fan's words, his master unexpectedly appeared at the doorway, instructing him to follow the other's suggestion. For a moment, Qing Feng was utterly astonished. Could it be that the method Ding Fan mentioned was actually true?
Qing Feng clearly knew that he had been an alchemist for some time now. He had seen and heard much about alchemy, but he had never heard of preserving spiritual materials in an alchemy cauldron. Importantly, he was his master's apprentice, and his master had never mentioned such a method. His master had taught him everything with utmost dedication, so clearly, even his master didn't know about this method.
Yet here was a mere cultivator, seemingly at the Early Nascent Soul Stage, speaking with such confidence. How could this not be shocking? It was truly an unbelievable thing!
