Pablo had figured something out when the Dragon King and Demon King were talking.
First, the dragon King wasn't all that smart. It was very easy to find who had summoned all those suns and yet, the Dragon King took a lot of time to figure that out, that too with the help of the Demon King.
The second thing, Pablo already knew about it. The Dragon King was prideful. He was suffering from a superiority complex, so much so that he didn't believe that the ten people who killed his whole race and him were none other than Gods themselves.
Therefore, Pablo decided to use exactly that when he saw the Dragon King was about to burn him to cinders.
He told the dragon that the being could kill Pablo anytime he wanted but more than Pablo, there was another person that the dragon King needed to kill before anyone else if he wanted to truly live like the King he was.
The Demon King. Dravakos.
El'Dorado heard Pablo and went silent.
