'Who is he? Why don't we have any information about such a human with dual elemental spirits?' The main demon general still felt there was something wrong with the human in front of him as he continued to question himself.

'Also, how can he train his two elemental spirits to have such a terrifying attacking power?' 

All the high-level demon generals valued their life very much. Even if there was a small probability of them dying in a fight against someone, they would directly escape.

Just like how Edmond was unable to kill an elite demon general in the past but kill him in the fight a few hours ago.

He killed that elite demon general before he could even think about his defeat. So, Edmond was able to kill him.

Here, the main demon general still thinks that, if he wants to escape, that human could not stop him. That's why he was still waiting for a chance to kill him and waited for that human to show his other trump cards.
