Don’t Concern Yourself With That Book - Chapter 204

“I got transmigrated into a novel because of a bad review?”

Eren found his life turned upside down when he woke up as the character that he had just finished cursing in a negative review!

Not only had he been reborn as an antagonist that he hated, but he was an Elder at a Devilish Sect?

It would've been fine if that was the only problem, but that was just the beginning as he remembered that the Character was a spy sent into the Devil Sect by the Mythical Hero Academy... A character that died within the first fifty chapters?!

“The Demon Lords are bringers of destruction, and among them, I am the strongest.”The Demon King has fallen, slain by the Hero in a battle that shook the heavens.After this, humanity knew a long era of peace and prosperity, with the hero now at the top of the world.Fifty years after the battle, the demon race is resurfacing, but now with the throne empty, they must fight for the emergence of the new Demon King. Meanwhile, the humans are preparing for the rise of the next hero who will oppose their archenemies.Born as a mere stable boy in a lower-class noble household, Bel has lived his life tending to the noble gardens, pruning roses for banquets he would never attend. He is nothing more than a lowly servant in a world ruled by noble bloodlines and magic.However, his fate changes when a demon attack devastates the household. As flames consume the estate, Bel is about to be executed in front of his master when their leader, a great demon, recognizes him as a member of a powerful species of monsters that had disappeared before the ascent of the previous Demon King.She calls him by his true name, awakening his true blood.The demon, intrigued by this discovery, decides to spare him out of curiosity and pity. Having learned about Bel’s true nature, his master, rather than executing him, chooses instead to bring him into the heart of his household, seeing in him an opportunity to elevate his family’s standing by binding a powerful being to his service.But power cannot be shackled forever, and among them, the one in Bel's blood is the most dangerous.

An Xu opened his eyes and found that he was in a world with both ABO and supernatural abilities.
She pinched her face hard, but it didn’t hurt at all.
So this female alpha and lightning power user happily thought,
It’s rare to have such an interesting dream, and I’m blunt. (=￣ω￣=)
A painless aristocratic girl who traveled to the world of ABO+ supernatural powers,
The mentally retarded otaku who thinks he is dreaming, lives as he pleases in another world,
I mistakenly hit the promotion and salary to be a unparalleled king.

Female A male O, simple and rude middle school girl (female lead/alpha) X feeds a tiger brain to make up a knight (male lead/omega), cool writing, puppy blood when falling in love.

An Xu: Hey, am I not a teacher of justice?
Chris: ……………
Everyone: (No, no, I don’t think it looks like the villain’s side is better!!)

hint:
1. ABO world view, female A male O (say important things twice);
2. The heroine thought she was dreaming, and for a long time has been the crazy devil king in the eyes of everyone, and she is absolutely not pure and flawless in terms of morality
3. The hero Chris is a growth-type holy father, gradually evolving
The above points should be cautious, if you can’t accept the setting, please let it go
