LITRPG/ mc enters a world he doesn't know anything about

[Stephen]

Read this book last year during lockdown. I had brain surgery this year and cant remember much from the book but these few things:
1. the mc removes a slave collar from a female that ends up being the mother of all dragons.
2. receives a quest to enslave a god for a goddess.
3. uses mana to charge a cannon on an airship.
4. stops another kingdom from taking over another kingdom.
5. go on a quest to receive drow relics.

Thats about what I can remember. I hope you all can help

Hey Stephen,
I'm sorry no one's replied until now! :S Are you still looking?

Is it possible that Parker is looking for the same book?
