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

- Description from novelbuddy

Just as a gamer found an overpowered skill book called ‘Item Upgrade’ in the hottest virtual reality role-playing game on Earth, something happened to the game’s system, causing his soul to leave his body and go to another dimension. Common sense dictates that he would be born anew then become the greatest overlord of this world by making use of his advanced knowledge. Not in this case! He was already dead. Only some fragments of his soul and that skill book managed to get into that dimension and merge with an ordinary common youngster called Bai Yunfei.

This was the enormous Tianhun continent, where humans could be said to have no limits. There was a group of humans here who could cultivate the power of their own souls then control their bodies, the natural elements and even other people’s souls with that power! These special beings were called — soul cultivators. Come witness how the several fragments of the dead inter-dimensional traveler’s soul and that skill book, which was not governed by the laws of this plane, were going to help Bai Yunfei become a legendary soul cultivator and craftsman!

The Strongest Magic meets the Mightiest Mecha.

I have stolen Golden Mechas from the deepest vaults of the most tightly guarded fortresses in the world.

I have personally destroyed more armies than the top three superpowers have in the span of the Absolute War - combined.

I burned down the terrorist megacity of Habon.

I was expelled from the Union of Heroes at a younger age than people are allowed in.

I have talked to Ancient Gods, loved women, and devoured mechas that would make superpowers cringe in fear.

I have faced demons head on in moonless nights others fear to speak of during the day.

I am deified in a thousand cultures, and labelled as the devil incarnate in the rest.

I am the Mecha Emperor.

You may have heard of me.

Excerpt from Chapter 1

This is where it all began.

A junkyard.

Oh no, this isn't your clean, mechas-only junkyard that was the 'starting point' of many mecha geniuses out there.

I have seen and heard my share of rags-to-riches stories, and many of them claimed that they had started from 'junkyards' and slowly grew to be where they were right now.

From Zero to Hero, they declared.

You can do it too, they said.

As long as you work hard, everything is possible, they claimed.

I call bullshit.

Life doesn't work like that.

Crying blood and tears, she pledged a poisonous vow. The gods did not fail her. She was sent back to a decade ago. The legitimate daughter of Jiang family returned from hell.

Forget it, whatever! Since they already claimed that she was a temptress that wrecked the country, she shall overturn the world into complete chaos starting with her beguiling sister, her malicious stepmother, her cruel lover and her heartless family. Let her end the lives that Yama refused to end.

She was a pawn in her past life. In this life, however, the world was her chess board. With an alluring smile and a charming figure that enchanted the entire nation, the red-clothed woman wrecked chaos among the lands. She was a vengeful spirit from hell, determined to make those who wronged her pay in blood.

“I want those who owe me a life debt to hold their hearts out in front of me. I want those who looked down on me to only be able to admire me. I want Lord Zhong Zi to shiver when he sees me. I want to step on this splendid river and mountains!”

“You are a temptress and I am a thief.” His robe was as dark as the night and his gaze was as cold as the Northern Star. “A perfect match.”

Her red dress was akin to fire, but her heart was the coldest ice in the winter.

He was stoic in his black robe, yet he was willing to warm her frozen heart.

In this life, the elegant man seemed like a snowy bamboo grove with tall, chilly mountains, walking step by step towards her like an unstoppable force.

“Ruan Ruan, if you hate the world, then I shall conquer the lands with you.”

“What if I love the world?” She asked.

“I am the world, so you can only love me,” he answered.
