I didn't know it had a light novel version, would you be able to tell me where to go to find it and read it?
Here's a link if you haven't gotten it yet. http://shiroyukitranslations.com/long-live-summons/
The story does change greatly between the manhua and LN version. Well which version is better is up to your liking. Anyways enjoy reading.
I'm already reading a light novel at the moment but this will definitely be next on my list of things to read. Thank you so much for providing the link. ヾ(☆▽☆)

A manhua version sometimes destroy my imagination of light novel version. I don't like the art to be honest.
