Even for someone like Chen Yan, a cultivator whose physical body has been nourished and is well-suited for cultivation as a "Dao Body," his affinity for Heaven and Earth Primordial Qi was merely "excellent."
But if this material has a perfect affinity...
Chen Yan immediately understood why Xie Jiuyan turned such a thing into his own bone.
With a perfect Yuan Qi affinity, during cultivation, Heaven and Earth Primordial Qi can enter the body without any resistance!
No delay, no obstruction, no loss!
In fact, due to this perfect affinity, it would actively attract the gathering of Qi, making cultivation twice as effective with half the effort, even calling it modestly.
The first question is, where did Xie Jiuyan get this thing?
The second question is, is there more of this thing available!!
Chen Yan sighed.
It seems his words to Wu that they wouldn't meet again might come to naught!
