Is there any side story of the Douluo Continent's Limit Douluo manga?

Answer 1

I'm not sure if there's a side story to the Douluo Continent's Limit Douluo manga. However, in general, manga and novels were usually published by the comic publishing house or the copyright owner instead of being published directly by the novel publishing house.

If you're referring to the additional content added to the comic book, perhaps only the comic book publishing house will edit and publish it. You can ask the comic book publishing house or copyright owner if there are any plans for a side story to better understand the physical comic book.
