Someone once asked me, "What's the most dangerous job in the world?"
I told him, "Being a novel editor."
Because the authors might well be writing about things they've actually experienced.
That means you might have to deal with transmigrators, retired heroes, active demon kings, useless Heroic Spirits, Ultraman, and even Outer Gods.
And these self-important types are a bunch of unreliable jerks who often miss deadlines and fail to update.
That's when the editor steps in.
Our job is to promptly pry the new manuscripts out of these jerks' hands, brains, bodies, and even their nether regions.
See? It's that simple.
