Fang Xi's interest was piqued, and his divine thought suddenly spoke.
"To be honest, if you knew my true identity, you would find it unsurprising that I could recognize the Kuyong Skills at a glance. As for discerning the real from the fake? I have practiced a secret skill, which, though not greatly useful, is quite profound in distinguishing between the second Nascent Soul and the original body."
Elder Yin chuckled hehehe.
"Then, may I know, who are you in reality, Elder Yin?" Fang Xi was curious.
"To tell you the truth, I was once the headmaster of a certain generation at Green Emperor Mountain. I even accomplished quite a bit during my tenure. Later, I relinquished my position to seclude myself and break through to the Deity Transformation Stage, becoming the only figure to attain such a status at Green Emperor Mountain in those years!"
The shadow within the prohibition sighed, "Tell me, why would I understand the Kuyong Skills so well?"
"Impossible!"
