Harem Startup : The Demon Billionaire is on Vacation - Chapter 143: Big Mistake

In the midst of the blue and purple neon lights, under the gray, metallic sky, it is the frontier of all data, the aftermath of a scientific revolution, also the border of fiction and reality.

Steel versus body; the past and the future.

Here, the Outer World and the Inner World exist alongside each other. It seems like the wall of time is right in front of your eyes.

Darkness gradually swallows the world.

But listen, my friend, we cannot use kindness to survive the darkness. We need fire.

Hey Guys, this story is written by Sinyk on fanfic net. This is not my work. The only reason I am putting this up is because someone has copied Sinyk's entire work word-for-word on this site (claiming it as his own: Harry Potter and the 7 angers), releasing it at a snail's pace, and is also making money off of it on patreon. Pisses me off to no end.Art is by CruderFive1 on DeviantArt-----------------------------------------------------------------------------------------------Disclaimer: The Harry Potter universe belongs to JK Rowling, Scholastic, Bloomsbury, Warner Bros and some other high falutin' companies. Me, I'm just a PR professional. I don't profess to own - and would never dream of making any money off - JKR's wonderful world. However, its her sandbox and she's left the gate unlatched so we can go in and play a bit. Which, I've done.-----------------------------------------------------------------------------------------------Okay, guys and... guyettes,This one is of epic length. And by that I mean really really long. For those who sent me a note about 'Four Heirs' and thought it long - well, this one blows that one out of the water for length. So, if something only up to - say - 150k words is your cup o' tea, then this isn't for you. No sir-ree! This story hits approximately 480k words.To stop all the whining and bitching right now - yeah, like that's ever going to happen - you'll figure out this is a 'Haphne' story; Dumbledore is (somewhat) good but still manipulative as per canon; Ron's an ineffective non-entity; Snape tries to keep sticking his beak in - and get's it repeatedly thwacked with a rolled-up newspaper; McGonagall gets over her hero-worship of DumDum (I mean, Dumbledore); Hermione is a good friend; Sirius is free; kids are kids; and teenagers are walking bags of hormones.The story follows canon a lot; and I've even included many quoted sections out of the books. I didn't do this to pinch JKR's works. Rather, it's in there to demonstrate similarities while being a different story. So, no biatching about that, either. You've been well and truly warned.Yours,Da crazy bastard who thinks he's an author.
