Moby, who was still in a state of shock, was on the dirty, muddy ground, staring at the black night sky above him that was unobstructed by any trees due to him breaking them during his impact.
His face bore the impact of what like a canon, despite his efforts of trying to block it in the last second. Luckily, although he felt extreme pain in his shaky face, there seemed to be no bones cracked or broken which would have taken a bit longer to heal with his demon regeneration.
Moby could have easily forced himself to stand back up and fight but he decided to play dead for a bit longer just to have time to himself as he needed to completely rethink his plans of attack.
When he read that he had a sound ability, he had no idea that it would lead to what happened. In his mind, he thought that he would have extremely loud screams that annoyed and messed with people's ears allowing him to attack while his enemies were distracted, but he was sorely mistaken.
