Only the monster was seen writhing in agony and making an unpleasant yet sharp noise, so Ye Wudao was certain that this creature was definitely not human, but some unknown monster somewhat similar to human form in appearance.
Moreover, most importantly, this monster could perform invisibility technique. If it weren't for Ye Wudao's Yin Yang Eyes, it would have been indistinguishable. He wondered just how many such creatures were in this forest, which made Ye Wudao cautious not to close his Yin Yang Eyes.
After Ye Wudao had struck the monster hard with a punch, it was clear it was no longer alive—his breathless body becoming visible. It was only then that Tie Dan caught sight of the creature that had just injured him.
And this humanoid monster's hideous appearance startled Zhao Xiaodie so much that she dared not even look at it. Instead, she fearfully asked Ye Wudao, "Oh my God! Wudao, what kind of monster is this? It looks so disgusting!"
