Once the battle was done, Kretos could feel his body aching all over. Once his muscles loosened up a bit the pain he felt was immense. He fell to the ground no longer able to move. This was a similar situation to when he fought Darius, but way worse.
His consciousness drifted in and out as Kretos felt his body growing a bit cold. His breathing was becoming heavier as time went on. His mana was now fully drained and his wounds were no longer healing.
If he were to die like this wouldn't it be so lame after what he said to Kir? He even told the old man not to worry, and that he would crush the heavens itself. Yet here he was laying on the ground unable to do anything. Even his eyes were shut tight but his other senses were still working properly. What made it worse than the time after he fought Darius was that this time he wasn't losing consciousness, he was still awake but unable to do anything.
