Please recommend me something good based off these series

I have read and loved Defiance of the Fall, Primal Hunter, Shadow Slave, Divine Apostasy, and He Who Fights with Monsters.

They are all great series but have one thing in common, they are unfinished and ongoing.

Looking for a series with:

1. LitRPG & progression elements
2. Male MC with rationale mindset
3. Long Series that is finished (or close to being finished)

Also I've read Cradle, Mother of Learning, Worth the Candle, HPMOR, The Perfect Run, and Reverend Insanity so no need to recommend those.

Thanks!
