'8 wing demons and 1 human knight flew into the mountain cave?'
After hearing this news from those bats, Zhang Tie became dubious at once. It was not strange for wing demons to hide in this mountain cave; neither it was strange for a human knight to stay inside; the point was those wing demons and a human knight stayed with each other.
'Is that human knight the missing earth knight or someone else? It's a problem. What was more, why would this human knight stay with wing demons?'
As bats had limited intelligence, Zhang Tie couldn't get details from these bats even being a top animal controller. He couldn't know how the human knight looked. Zhang Tie only knew that that human knight almost flew into the mountain cave together with 8 wing demons at the same time. Those bats didn't know the levels of those wing demons; however, Zhang Tie knew that the human must be at least a black iron knight as he could fly.
