I reincarnated as the villain's father

Well, I'll be giving this review when only 6 chapters have been uploaded. Seeing MC being reincarnated as a Villain's Father is actually a first for me. Can't say much since the story isn't explained as it's in the Prologue part I would say. ISW, the MC is reincarnated in a novel he read in his past life as the FATHER, I Repeat FATHER of that novel's villain meaning he already has a family [Wife, Son(Villan)] and a business empire and is the most dreaded man. The System, now how should I say it. It is a typical Trash talk pseudo-useless system which I think is okay for some Comedy and filler paragraphs. It has a very straightforward and unique function which is to multiply the effects of whatever the MC does. I am going to read it since I like and want to know what the story has to offer. NOTE FOR AUTHOR-san:- Read 'I am the Fated Villain' or 'After Reincarnating, I became a second generation villain'. You should get some ideas.
