My demon God system(being revamped)

the demon God that's what the world named me, yeah I know it's a cringe name but what can I do I mean I didn't even do anything bad except for maybe killing one or two corrupted kings, defying the holy lands, and making fun of some gods but alas I am just a mere human and a human has his limits so I died to my worst possible enemy but at least I didn't die a virgin that would have been shameful and at the last moments of my death I thought that was it I go poof but rather than going poof I reincarnated in some other world here the martial arts and magic are the norm and the world has developed due to something called science now that I am back time to do what I do best and that is to have fun and cause chaos ------------------------------------------------------------------------ the cover ist mine if it's yours just let me know and I will take it down I am a newbie writer so bear with me also if you want to motivate me pls follow me on insta insta - that_clumsy_guy
