Pretty good!
The writing style is a bit overdone for me and seems to lean a bit too much towards hammy parody for my tastes, but it's pretty good in spite of that. I cringe a bit when I read it, but that's my personal taste, and I'm sure there are people who like that sort of writing style. Not personally for me, but I can appreciate it for what it is. Ah, but if I had to describe it, I would say that it definitely reads more like a Chinese web novel than a proper written novel, so don't go in expecting the latter.
The characterization isn't the best, but they roughly follow along with how the characters are in the story (with the exception of Rudy, of course). I'm sure that will improve as the story progresses and the author gets more comfortable with each character's voice though.
It's interesting to see how this Rudy leans into the child genius route instead of trying to hide it. I do wish that there were more deeper explanations on how he was able to pick things up instead of handwaving it as just being a genius, but that's not the point of the story, so it's fine.
I personally don't think that Rudy would be able to improve so rapidly in terms of physique and sword techniques due to the fact that his particular Laplace factor prevents him from accumulating the Battle Aura needed to perform some of the higher level ones, but I'll take it as a given that this Rudy just has that nerf removed.
In terms of plot, the broad strokes are the usual sequence up until he leaves home. Childhood magic training, meeting Roxy and learning magic... etc. There's not too much new in here. Rudy learns to hunt and interacts with the villagers a bit more, and he also fights some monsters to test out his powers, but it isn't too significant. The reactions of everyone to Rudy's talent is kind of funny though.
I do wish that magic wasn't handwaved as much... And, er, that the author knew a bit more of what he was talking about when he tried to bring scientific explanations into things, but I understand the limitations of that. Just don't expect perfectly accurate rationale behind how some things work.
Seeing Rudy becoming a magic swordsman is super interesting though. But it seems like the author is eager to get to the meat of the story since a good portion of the intro reads more like a log than events unfolding. Than again, it's similar to that in the original, so it could just be mimicry of the source.
Fight scenes are a mixed bag though. There are great parts that are a blow by blow exchange, but then there are other parts that are just summed up and skipped over.
One part of the story that does bother me a bit though is how everyone is stunned into silence by Rudy's magical sword style. I get that it's amazing already, and I get that it would amaze other people but reading about people being impressed over and over again gets a bit dull.
Right now (As of Chapter 26) we're just starting to really change things up. Instead of teaching Eris math and normal things, since Rudy becomes Ghyslaine's student, he gets rolled in as a magic tutor/bodyguard.
It's an interesting change, and I'm curious to see where it ends up.
