Doing Good Brings Blessings

'''Introduction to the Work: - If you do good deeds, you will be rewarded? - If you act in accordance with social standards, the user's restrictions, 'Jeong Daon', will be weakened. Doing good deeds will bring blessings? Even if my past life was that of a demon king? It's been 19 years since I closed the tumultuous life of a demon king and reincarnated on modern Earth. I was forced to become a hunter due to the system. And I have to do good deeds to regain my original abilities? "Hmm... I guess beating up bad guys counts as a good deed, right?" That's not a bad idea. Modern society is a place where demons can easily infiltrate.'''
