Blood Evolution System - Chapter 30: Creating a trump card

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

Her – a glutton without troubles or worries who crossed over and became a young fat chick with a deep vengefulness.

Him – a young master of the number one power; a two-faced man with elegance and charming, good looks; he is the chosen one of the former saint god and a man who will only bend his back for her alone.

This domineering crossover’s slogan is, ‘Don’t touch if it is this sister’s, put it there if it isn’t this sister’s!’

…watch how the Domineering Glutton and the Two-Faced Venerate Emperor create sparks as they meet and collide, stirring the whole Spirit Treasure Continent into turmoil, how they fall for each other and how they kill each other, how life and death severs love.

Long ago a great calamity struck the earth, destroying much of it and merging what remained with pieces of other worlds.

With these worlds came Aether, a new form of energy that can allow one to transcend the bounds of normal mortality and human limitations.

In a world where humans absorb the essence of aether beasts to gain power, Aiden Hawke joins the class of humans known as arcanists, people who defeat aether beasts and absorb their essence into cores they forge within themselves, and who infuse themselves with the aether that permeates the world around them to increase the power of their body and mind.

However, unlike most, Aiden will find that he holds a unique gift and that his journey as an arcanist will not be so simple.
