This Book Was Written by the Demon Lord

I'm not sure what's wrong with my writing, so I've decided to take some time to study. Hopefully, when I return, I'll be able to bring everyone a better story.

Blurb:

This world was created by immortals.

Heroine: System, you want me to help an author who opens with a line like that climb the rankings? In the modern romance category, no less?

System: The great "I Am the Demon Realm's Mountain King" is telling the truth, you foolish humans.

Heroine: Fine, I'll treat it as modern fantasy. But what's with the next line: "The Demon Realm's Supreme Lord is the highest being in the world, and all creation bows at his feet"?

System: What's wrong with that line? The great "I Am the Demon Realm's Mountain King" even used an idiom. How elegant and beautiful!

Heroine: As a human at the top of the food chain, I refuse to bow, and I want to offer you a complete quit-reading package.

System: Oh, pay me back.

Heroine: Hehehehehe, I'm kidding! You know I dote on you.

System (something seems off, but it can't quite say what): …

The Demon Realm's Supreme Lord became obsessed with online fiction from the human world. On a whim, he registered under the pen name "I Am the Demon Realm's Mountain King" and began his own demonic writing career.

But eight years passed, and his click count was still pitifully low?!!

The Demon Realm's Supreme Lord was furious, but too embarrassed to reveal his ID and have his demon minions boost his rankings.

So a ranking-climbing System that combines demonic power with high technology was born…

The Demon Realm's Supreme Lord: … This woman is unexpectedly, infuriatingly interesting!

● In short, it's a story about the heroine transmigrating into a silly novel.

● The heroine transmigrates into books regularly, interspersed with her modern life.

● A 1v1 face-slapping story. Sweet, sweet, sweet.

● Please add it to your want-to-read list!
