Ping Zhou immortal king and another immortal king felt extremely uncomfortable with this chi even though they were behind Ye Mo. They respected Ye Mo who took the full force of it. They were all immortal kings but they were far from Ye Mo.
Ye Mo used a wave kill the instant he got near this level eight demonic immortal spirit beast. Ye Mo saw now that the demonic immortal spirit beast just reached level eight for no more than 10 years. He couldn't completely control his chi and was in a state of extreme volatility. One could imagine that once the level eight demonic immortal spirit beast consolidated his chi, he would seem not much of a threat but he would truly be a threat.
