Ning Siyu stared at Ye Yuan, the confused look in her eyes becoming thicker and thicker.
She discovered that the things Ye Yuan said, she actually understood less and less!
What this guy talked about, was it really rank three alchemy knowledge?
But opposite of Ye Yuan, Xiao Feng had an appearance of learning with an open-mind, but his gaze became brighter and brighter, feeling a sense of enlightenment.
The agreed upon interaction became a one-sided clarification of doubts now.
At the same time, he was also shocked to the extreme in his heart.
Several decades had already passed since the two people had an exchange the last time.
He discovered that now, he was already completely unable to exchange with Ye Yuan on an equal footing.
What Ye Yuan talking about was another realm, giving him a feeling of beholding a great mountain.
