Im looking for novels like Release that Witch. I want the mc to use his knowledge from earth. His knowledge could also be from a alien world or something.
I think you might like A Hero's War. It's an English webnovel, but I feel that it's the closest one to Release that Witch, especially in terms of using Earth Technology in a magical environment.
How about: https://www.novelupdates.com/series/miracle-throne/ The MC has advanced knowledge from the future. https://www.novelupdates.com/series/the-human-emperor/ The MC has earth knowledge and future knowledge.
these are a bit different but Common Sense of a Duke’s Daughter is similar and Akuyaku Reijo Ni Koi Wo Shite has some kingdom building in it later in the story but most of the really similar one were said above.
When A Mage Revolts, is a bit similar except in this case the MC also has magic powers and the mages has a more general magic use instead of a single ability. another one is Throne of Magical Arcana
