“Obtaining the topmost degree of talent in sword arts in the world requires giving up 72 years of lifespan, which leaves you with only five more years of your life. At the same time, you will never be able to feel love, kinship, and friendship, and you’ll end up leading a lonely life until your death, unable to procreate, or to have any descendants.

“From now onwards, everything related to happiness in the human world shall no longer be of your concern. Are you willing to accept this?”

“Hahahaha, I’m already alone bereft of all support, my hopes dashed to pieces, shouldering only absolutely irreconcilable grudge and hatred, why would I disagree? Why would I not want it? I couldn’t ask for anything better!!”

His sword sweeps across the Divine Continent for seven days and nights, moving 90,000 miles through the starry skies, unhindered.

He slays saints and buddhas in Heaven, slaughters demons and devils in Hell, sweeping away all the grievances in his heart.

It was a life without regret. My parents were in good health, and I wasn’t homey enough for me to combine my studies and part-time jobs.

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!
