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

"Then let's teach him a lesson and take revenge!" 


"Huh?" the girl raised her eyes that had widened in confusion! What does he even mean by that? What kind of revenge could she take on him?


"Do not think too much! Just leave everything on me! I will handle it!"  her bewildered eyes stared at him for a second but before she could ask him what he meant, he had already started dragging her out of the room!


"Wait! Where are we going?" did he want her to go and confront Han! 


Wouldn't it mean she would make a joke of herself there? No! She would not go! She could not go! 


"Wait! I do not want to go there and meet him where he is enjoying his time with another woman! Even if it was a setup by her mother, he could have denied it! I would not forgive him for cheating me!" she tried to stop hum but Hao did not budge as he kept dragging her.


"Ah! I know! I am not asking you to confront him! But I want you to teach him a lesson! He deserves to be taught that he could not play with you!
