Mo Fan and the others were stunned by what Ren did. Either Ren was an incredibly stupid person to fall asleep in front of strangers or an incredibly powerful person who didn't see them as a threat at all. After witnessing Ren's fight against the Sand Dragon it was obvious that Ren was the latter of the two.
"Are we really going to bring him back to the city?" One of Mo Fan's men spoke as he looked at the unconscious Ren. "We could just leave him here and based on what he said it doesn't seem like he knows his way around here, so he wouldn't be able to find us."
"So you want to leave behind the person who saved us?"
"You heard what he said it was just a coincidence that he rescued us. Also, are you sure we should bring such a dangerous person back to the city?"
