Blasphemy was shook down his core when Drago surprisingly came out of his fire breath almost unscathed. Though he wasn't push that much from where his humongous body stood, the damage inflicted was something to be concerned of. The owner of the seven-headed dragon was only one, so, if one of the seven heads get hurt, blasphemy himself would be feeling the pain as a whole. He has seven head to operate but there's only one brain that was operating them.
"H-how are you able to withstood my flames?!"
As if Blasphemy was still shocked by the sudden rapid regeneration ability of Drago. He was healing at such a rapid rate. The way he was stuttering when he spoke says it all.
"You couldn't believed it right? The fact that a mere premature dragon's kin has punched you right through his face states that I am not to be underestimated."
"It seems that I have really underestimated my own kind. What a disgusting discrimination I conducted."
