If you accidentally bind yourself to a cheating system, don't be thrown into the dimensional world to do tasks. Forget it, it's a fairy tale fantasy, it's a drama with two male protagonists, so I'm here to kill someone?
"System, please explain to me clearly what is going on! If the ending is not very good, why do you want to change it? I think you asked me to kill people!"
"Master, don't worry. Although there is no heroine in this world, one of the four ghost kings is ownerless. And most people don't have a partner yet and are still single."
"So who am I going to attack this time?"
"Master, what you want to attack this time is the one of the four ghost kings who has no partner yet. Stop the ghost king from turning dark and save the common people."
"Oh, saving the common people? I am not a god, so the life and death of ordinary people in the book is none of my business."
"Uh..."
"Master, although these things in the book do not exist, they have been created after all. Although they may appear false to the outside world, they do exist."
"Okay, let's get started. Finish early and come back for the next task."

Concept: There is no world, but there is a paradise
