Reincarnated in Custom Made Demon King

This story is about a man that got reincarnated in CMDK and trying to get to the top. Here what you can expect in the story: *The mc is a villain and he will do a lot of horrible things. *The mc will act more like a devil and use his brain. *I changed the system so it will be less artistic and more like the system read his mind and create what he picture. *there will be a harem of 3-4 but it will be a sub plot later. A little about myself- English is my second language but don't worry I'm pretty good at it. This will be my first book. I plan to update twice a week in Monday and Thursday. I hope every one will enjoy my book and if you have any constructive criticism feel free to write it in the comments.
