Reincarnation Of A Swordsman: The Omni Mage

Despite the rich explanations about magic, runes, so on and so on, the plot is going nowhere... I mean, maybe the title should respectfully change to "The Reincarnated Swordsman in Mage Academy" or something along those lines. I'm already in chapter 104 and not even 3 months has passed in the story. I mean..... Ok so how long are we going to stretch this "building power" in school arc? Bcs for one, the MC are not exactly that charming enough to keep me going, and the side chara lacks personality and back story. If the pace could pick up a lil faster maybe this would be great or maybe if this story has a fun cast of characters it would be a fun comedy at academy kind of story. So yeah, good world building but can we fasten the academy arc a lil bit?
