Towards the middle-aged man's identity, Ye Yuan had already deduced it. Hence, there was not really anything surprising.
In truth, when Xiao Changfeng's soul force pounced towards Ye Yuan earlier, Ye Yuan's first reaction was to retaliate.
But he reacted very quickly. Xiao Changfeng most likely held suspicions towards his identity. Therefore, he might as well release his divine soul and let Xiao Changfeng examine freely.
Ye Yuan did not have much attainments in disguising skills. But in the camouflaging of the divine soul, who in the Lower Realms could match him?
Although they were all humans, on different planes, human souls still had some slight differences.
This point, Xiao Changfeng knew. As an Alchemy Emperor, how could Ye Yuan be ignorant?
Hence, ever since eliminating Lan Bao, Ye Yuan already camouflaged his own divine soul into the appearance of a Fierce Gale World's martial artist through divine soul mystic arts.
