After watching Feng Xiyun leave, Ye Xuan returned to the Cloud Sky Palace. Once there, he began to study the refining method for the high-grade soul returning pill.
The reason why he wanted to refine it secretly was not because he wanted to hide it from his disciples, but rather because he did not want to make a fool of himself in front of his disciples for not knowing how to refine this pill.
The refining method for the soul returning pill he taught Feng Xiyun was something that Chief Tian Xuan had left for him. He himself did not have a deep understanding of alchemy in the mystic world.
After seeing Feng Xiyun refine a pill in one attempt, Ye Xuan could not help but feel a little nervous.
If he did not succeed on his first try, as her teacher, would he not damage his reputation and image?
As such, he had to practice secretly. Only once he had successfully refined it would he show and teach it to Feng Xiyun.
