Wing demons were very flexible in the sky. They could fly and slide rapidly like birds. When in need, they would hover in the sky while flapping their wings like dragonflies. They could even turn around and fly backward. Actually, they could fly in any direction at any time. Such great flexibility could barely be matched by any bird in the sky. Although Zhang Tie's thunder hawk could easily fly faster than wing demons and could also hover in the sky for a short period, it couldn't fly backward like wing demons.
As air cavalry I airplane had a pair of fixed wings and relied on mechanical strength, its flexibility couldn't match that of wing demons. Even so, air cavalry I airplane still had an advantage——speed. Air cavalry I airplane could even fly faster than battle spirit wing demons, not to mention LV 9 wing demons. If speed was regarded as the only reference, air cavalry I airplane was much more powerful than wing demons.
