After Ye Yuan left, Coldfeather said with an astonished look, "This … He should have just broken through not long ago, right? He's already able to refine such a high level of difficulty medicinal pill?"
Xuan Yu mused for a moment and said, "The power of Dao Realm is not what the likes of us can surmise. To us, we're still stuck at the shallow realm of seeing a mountain as a mountain. He has likely already reached the realm of seeing a mountain as not a mountain! What he came into contact with is the source of Alchemy Dao. Learning yields twice the result with half the effort. It is far from what the likes of us can imagine."
Coldfeather was completely clueless about Alchemy Dao, but he knew Xuan Yu's strength.
Xuan Yu saying this showed that Ye Yuan's Alchemy Dao boundary was already unimaginable.
