You are thinking way too literal for a High Tier fight. It's fantasy. It holds the same logistics as to why someone in a high tier can level an entire city. He can do it...because it's fantasy. The laws of physics and realism are bent to an extreme. If maybe we were discussing mid tier then possibly it might be a requirement. 

But besides that, if you really wanted some form of logic an easy explanation lies in his species and the back story they have.

Don't think too much into it. It's high tier fantasy lol.
