Exiting Unscathed

It was fast! Almost making a slash on Zeras's face, he quickly shot backwards before turning to look at the dead creature. Right now, it had two-meter-long pitch-black, iron-like wings dripping black liquids...

"It seems sliding hands on their back slits would make them eject their wings out beyond their control," Zeras mused to himself as he walked back to the creature and swiped his hand over the liquid on it, and then...

TSSSSHH

Smoke rose out of his fingers as he watched the liquid burning away at its flesh, but it failed to penetrate his hands before it burned itself out.

"Their wings are also coated in venom that can burn away at the skin. It would be lethal if they can eject the venom at will. Even I would be burned to the bones if a bucket of the venom is poured on me," Zeras mused, a tingle running through his spine.
