Yan Lin was slightly taken aback by Fang Qingyu's retort.
The expression on her face turned somewhat peculiar, as if she had heard something unbelievable.
Her beautiful eyes widened slightly, looking at Fang Qingyu with a bit of disbelief as she asked back:
"You don't... know what the most precious cultivation resource in this Returning Mirage, the one that countless Transcendents covet, is, do you?"
Fang Qingyu was stumped by the question.
Instinctively, he followed her train of thought and replied, "Gray Crystal?"
Yan Lin's lips twitched slightly as she said, "Of course not..."
Then she forced herself to calm down, took a deep breath, and said softly:
"Of course not, it's Pure Crystal! It's a unique specialty of this Divine Armament known as Mirage."
