The strongest being in the world, even gods were vary of, the demon lord had killed all his opponents. He was the supreme with unparalleled strength and supreme powers, he could not be defeated. Looking down even at gods, he was not afraid of anyone. But who would have thought that he would be backstabbed by his own family.
Killed by his own brother, he decided to take revenge if he would get an extra chance. But when he opened his eyes again, he was on earth not in his world of demons and that also with a shitty “GOOD KARMA SYSTEM” that could only let him live if he would collect sufficient points by the end of the day. 
To earn the points, he had to do good deeds, and so his struggle to gain the points began. The man who had only cared about himself and only killed people like they were insects had to struggle and beg to help others so that he could get his long awaited revenge. 
But after doing so much goodness, would his system let him kill his killer for which he had come back to life and struggled so much?

Demon King's Good Karma System

"Wow! So do we have enough core stones to return now?"


He bent and started taking out the stones from the rest of the beasts without waiting for her answer. 


He had already taken out more stones then she had asked for so there was no reason for them to stop there.


The beasts had already informed their members and he was sure there were more to come soon. If they were any stronger than this, then they would not be able to fight against them.


It was already a miracle that they had defeated such a strong group. He could only credit their sudden attack and the beast's ignorance for that but they would not be that lucky every time they would fight.


He wanted to leave before their luck would wear out completely. But the woman did not reply as if she was still thinking on how more they could have before getting killed.


If she wanted to die, she was free to die, but why was she dragging him in that?


Where did he go?
