He knew very well that the Roc Demon King's capabilities were far inferior to his own.
Even if the Roc Demon King had undergone arduous cultivation all these years or received hands-on teaching from the Kunpeng ancestor, it still wouldn't justify such a terrifying improvement!
Moreover, those Magical Wings behind the Roc Demon King just now were definitely not simple.
"Your transformation just now, it simply couldn't have been as you claimed!" the Great Roc said with utter certainty.
If it were, he would eat the Summit of Pole Mountain!
Upon hearing this, the Roc Demon King shrugged his shoulders and said with a smile, "I didn't expect you to be so hard to fool. Indeed, I do not possess such ability. My transformation was thanks to another master."
The Great Roc completely ignored the Roc Demon King's backhanded compliment. His focus was on the last part.
"A master? What kind of master?!" the Great Roc quickly inquired, sensing something fishy.
