This is actually the chapter with biggest differences between webnovel and light novel's Vol.1 (or even overall biggest difference). Aside from one more thing, but on that I will write below. So, what's so different in the light novel compared to this? I won't go into the details, but they aren't big differences. There's an introduction of players' side flying division comprised of players who choose flying races (quite short, but still) and Tasha's fighting at the end was expanded by a few paragraphs.
Oh, and link here.
Now, next. I have a small notice to write about Chapter 16.
I will probably be skipping Chapter 16 of the webnovel, and maybe do it as a side chapter sometime. There are a few reasons for that. Number one reason is because author did not include it in the light novel. Next, the chapter is incredibly spoiler-filled, and introduces some stupid contradictions regarding the story. Simply speaking, it's really anti-story.
Though, I might change my mind depending on your reactions and get it up as per normal. Will think it over and you'll know on Monday.
