I was worried about what would happen if the constellations got angry, but… [The King of All Demons complains that the Demon King character’s pick rate is too low and begs for some fan service content.] [The First Elven Hero asks when their episode as the protagonist will be released.] [The Master of the Night fidgets their fingers, wondering if their character’s jaw could be made a bit more slender.] They… unexpectedly like it?

What if your own father and his mistress were behind your mother’s death? What if you were about to be sold off to a scumbag?

What would you do? In the nick of time, a tall, rich, & handsome guy descended from the sky and came to her rescue with a piece of contract.

Xin Qing glowered at the man before her. At first, she had thought of him as her Prince Charming, in the end, he turned out to be an evil demon.

“You’re not allowed to go. You can only marry me!” the man said viciously to the woman who was about to leave.

Fate, a gatekeeper who had been working for the castle, is beset by a few burdens.

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.
