The Roc Claw phantom was something standard Cain seen from even the lower realms of the Divine Boundless Heaven.
But the Space Roc Wings were a bit rarer than one would think. At the very least, Cain could not recall that much time when somebody was able to fuse their Dao Laws into their God Bloodlines seamlessly.
Cain knew it had to be that Xuegang just had that much perception ability to do so. Or she was like him who used a cultivation art completely suited to his bloodline and caused it to evolve on a certain path.
Xuegang was unaware of Cain's thoughts. The calm stare of his forced her out of her trance.
There was no shame in her as Xuegang directly bowed, saying with the utmost gratitude, "Thank you martial brother for the save. I dread to think what would have happened if not for you."
