This is actually the end of the series (I read it on a different site that included the note at the end saying so).
I have to say, I’m disappointed.
There are a lot of plot threads left unresolved (like who injured him enough to leave the North, when did this Black Sword Society infiltrate the Su family and are they still there, the inventions and business plot threads, etc.), and I also don’t like the female lead.
I assume it just wasn’t popular enough to keep going or the creator got tired of it, but I liked the story, for the most part.
