[System + wild imagination + fast-paced + funny and humorous + expansive worldbuilding]
One day, he awakens a System and thinks he can use it to reach the peak and get everything he wants.
But the System is a real menace, doing everything it can to torment its Host and make sure he never runs out of hardship or injuries.
The System comes from the ancient Netherworld Ghost Domain and may be connected to his grandfather. So, while completing the System's missions and improving himself, the protagonist also sets out to uncover the truth about his origins.
“You damn menace, is this how you treat me?”
“Next, I'll reward you with a pill.”
“Master Six, your humble servant pays his respects.”
When he wants a favor, it's “Master Six”; otherwise, he's just “you menace”...
In the end, it turns out the so-called System is nothing more than a divine consciousness his grandfather implanted in his body...
