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.

In a world fraught with innumerable dangers where living day by day is a struggle, a young man from the modern age transmigrated into such a world, accompanied by a peculiar system made for assassination.

This script was originally supposed to be about a Scum Gong x Cheap Shou — the Scum Gong abuses the Cheap Shou, the Cheap Shou became hopelessly apathetic, the Scum Gong became a Cheap Gong, and the Cheap Shou abuses the Cheap Gong.

That should have been the case!!!!!

But the script began to unfold—-

The Scum Gong was reborn to the past, and encountered the Cheap Shou who also got reborn.

The Scum Gong was horrified to discover that the Cheap Shou had changed his job and became a beast-like, ruthless, blackened Gong, ahhhhh help!

The f*cking miserable Scum Gong was taken and defiled, then defiled and taken, then after being taken from the front he was taken from the back, and finally he was taken into a loyal dog, sensual, tsundere Shou!
