Today's Hero

I'm Luan Qi. To make a long story short, I transmigrated into the game I'd been partly responsible for developing. That's not quite right. Rather than transmigrating into a game, it would be more accurate to say I'd arrived in another world. And I appeared high in the sky, to boot. I was completely bewildered as I fell from the sky. When I came to, I'd plunged down and run my sword through the Demon King, taking my level straight from Lv. 1 to Lv. 200. Title acquired: Hero. Max level and a limited-edition title on the very first day after transmigrating. Congratulations, congratulations. Now here's the problem. The most likely way to get home is to finish the story and end the game, but how am I supposed to advance the plot without a Demon King??? * Light novel. Max-level monster-slaying, lighthearted, no dark drama. Not a romance. Updated irregularly.
