Review Detail of Aceion in SPELLCRAFT: Reincarnation Of A Magic Scholar

I have read up to chapter 89 and the book has been enjoyable so far. My only issue is the main characters personality which sometimes breaks the immersion for me. As a grand sage in his previous life, I had some expectation that his personality would not be so childish. I can understand his overtly excited and emotional behaviour when it comes to magic, as that is the one things he loves the most, but whenever I read this novel it feels like the Mc should be a normal boy from earth who reincarnated into a magical world with modern science knowledge. Aside from when the author reminds us of his previous life as a old grand sage I always see the Mc as a normal kid. His interactions with other people whether they be adults or kids his age have no semblance of a reincarnated sage. And whenever the contrast does appear it breaks my immersion which is a bit annoying. In my opinion this novel would be much better if the Mc was either a normal child with some lucky encounters or a magic loving human from earth. If you can look past that issue then this novel is well written and fun to read.
