- Description from novelbuddy

Like most candidates, Zlatan's dream was a simple one. To pass the hunter's test, join a guild, hunt monsters and reach the A-class.Eventually, as he dreamed of, he achieved it hundreds of years later. Having sacrificed more than he could take in, using the most unthinkable and brutal measures, he became an S-class Hunter instead.Obtaining the Copper Flame back then after the Aura Awakening Ritual, that was his greatest flaw. Taking a span of 80 years to reach a D-class. Still, Zlatan Elmore became the most powerful hunter to exist.Falling on the battlefield against a Two-horned Dragon, he suddenly awoke as his 30 year old self. Given another chance at life, he didn't only have his memories but he's also given a Blank Scroll. This mysterious scroll doesn't only speak, its omniscient!

Seven billion humans living on the Earth time-traveled together after they had woken up one morning. They all heard a synthesized female voice.

What?!A perfect free-use novel doesn't exist?!.........So what? Just read this one.~~Hehe~~You're gonna love this, seriously.This is what cooking of three months is like.No degenerate out there can ever come close to my degeneration which helped me create this fantasy book.Milf?I have it.Young?I have it.Boob sizes?Is that even a question to ask.Ass size?Hmmm~~~ My favorite.Whatever you wish for, I got it.So come and follow the degenerate life of JakeMalcolm, the lucky son of a gun who was finally transmigrated to the world of his desire, using everything in his sight, his family the beginning and the end would be...Well, no idea who the end would be.So stay tuned to find out.~~First and foremost, this is a work of fiction. Any mention of a real person or religion is purely coincidental and all the work of my sick imagination.Read it, then decide if you want to stick to it. This is more likely a work of a whim so there might be holes that I might have to fill.Haha. Holes to fill.Anyway, this is more like an idea that progresses as the story does so if you have any fantasies that you'd like to implement, I'm open to them.Just don't overdo so the story doesn't spin too out of control.~~The cover's not mine and if the owner wants me to take it down, I'll do so without trouble.Bonus chapters of any sort would be decided upon once the novel goes premium, but before that, there is no schedule update. Just know that there'll be an update every day. Just not of how many chapters.Last but not least, read with an open mind and make sure you don't have any opinion to give until you're well into the story, whether good or bad.That's it. Enjoy~~
