Within a Hollow Heart - Chapter 140: Volume 2, : "The Road Back"

Lu Zhiguang is not a cannon fodder himself, but his mission is to save the miserable cannon fodder.

A few hundred years ago, Earth was affected by a mysterious force from the depths of the universe, triggering the revival of spiritual energy. However, things didn’t turn out as wonderful as humanity had imagined. The spiritual energy carried a strange power that caused the corpses of all living things to rise again, transforming into ghouls. And above these ghouls, even more terrifying beings existed…There were no ancient methods of cultivating immortality, nor any legendary awakenings of supernatural powers. But within the spiritual energy, there was also a presence of ghostly energy. This led to the emergence of Runes.Some people bore mountain runes, enabling them to move mountains and overturn seas, suppressing chaos. Others carried river runes, allowing them to reverse the flow of mighty rivers with a mere gesture. However, this process required a special profession to assist these rune cultivators—to constantly modify and engrave their runes, making them more refined and perfect.This profession came to be known as Rune Engraving.

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
