As Lin Mu observed the third prince, he started to recognize a few things about him.
There was Immortal Qi emanating from Feng Baxing's body but was restrained within the two meter area around him.
'His immortal Qi is swirling around him in a protective manner… just like the wind.' Lin Mu thought to himself, having picked on the skill that the man was using.
Lin Mu reckoned this was a defensive skill the man might be using. Though he didn't know if it was being actively used by him, or was there due to the armor he was wearing.
'No wait… considering the stability of the immortal Qi, it is likely to be from an Immortal tool… thus it should be the Armor itself.' Lin Mu determined.
