Error Reincarnation

Error was a overpowered guy, opponents became scared of him and moved away from him. Error was getting bored to the point he couldn't handle it, so he went on a journey to find the most powerful person he can battle with. Soon after, he found that the Dark Mage is the strongest on the planet. But he was too easy for me, while I was about to go search for another person to battle with, a person in the distance walked to me. Then he immediately appeared in front of me and stabbed me. I fell to the floor losing alot of blood and my vision fading. I saw white light and bright person descending from the sky, holding out his hand to me. Before I could grab the hand, my vision faded. What happened?
