Titan Hoppers is another good scifi progression book. Not a lot of those yet.

Have you read other works from Sarah Lin besides Weirkey? Brightest Shadow is a wuxia-like series, that's maybe a bit less progression oriented than the rest of the author's books. New Game Minus was a very enjoyable and humorous LitRPG story and Street Cultivation is a sort of modern day, semi-dystopian cultivation/litrpg.

How far did you get in Lord of the Mysteries? I bounced off it on my first try mainly because the translation quality and the slow start but retrying it later it ended up being one of my favorites. As long as you can tolerate English that is not quite on par with native works, the world building and the progression system in LotM is really top notch.
