The aura that Ray give is ominous, Zen subconsciously retreat sweat starts to drop from his forehead. For the first Zen retreat, another shoking moment for him. What's more he can feel the Qi surge from Ray. This was his mistake. He never know that Ray would try to use Qi, he should kill Ray while he had the chance but now it's too late for that. There is nothing he can do with it all Zen can do right now is fight back.
"Ready for round 2?."
Ray smirk.
Zen's forehead crumple, he's being mock by a zombie, he didn't want to believe it. A mere zombie mocking him, that hurts his pride as the leader of ultimate soldier, Zen tightened his grip, and ready his stance, this time Zen became serious. His pride has been shattered of course he didn't want to be looked down by a zombie.
