"Multitasking"

Under the 'stun' effect, Charles' wings reacted a step slower because he had to control his wings manually. 

This slightest mistake immediately gave him countless injuries from head to toe. 

Blood trickled down his wounds. Some blood icicles also got stuck in his flesh, continuously giving him pain and even slowed down his movement. 

But Charles was also a veteran. His muscle memory enabled him to cover his whole skin with feathers. 

Yes, it's not protecting his body with his folded wings, but directly growing hard feathers on his skin.

This is also one of the winged people's innate skills. 

Charles' muscle memory saved his vital areas from the blood icicles. 

The hard feathers covered his body like armor, and then his navy blue wings also didn't stay still. 

He knew it was better for him to make a cocoon like what Ainsley did when facing his intense attack, but he felt that he would lose if he did that.
