Chapter 639 Grand Success of Longevity Skills_3

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?

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!"

"Impossible!"
