Although it can barely handle modern weapons, it's uncertain against fully automatic weapons.”

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!!)

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
