Magecrafter
You're doing good on the plotholes part as Im struggling to find many. I would like more info-dump chapters, the magic system still feels too vague. Especially the differences between Mana and Miasma (and other forms of magic which I assume to exist), and if stuff like the law of conservation of energy still apply. Also I struggle to remember the core grades, I know I can just go back to chapter 0 but im wondering if the core colors have any other significance than just potency. It would be pretty cool if each core had their own specialities (or lack of) like the white core. An organization where members are op with different colors of the core sounds pretty cool. If the colors dont mean much please just use the colors in order of frequency or something. I wish there was more exploration of the unknown or something, like exploring ruins because the mc pretty much knows everything about where he's going and it's not that entertaining imo. That also reminds me that most of he history is about 500 years ago. You'll probably tackle ancient history later but some hints in the early chapters would be nice. Oh yea will we ever see him research magic, like in a lab? I can imagine lots of automatons and stuff just moving stones and vials around, it's why I came to this novel after reading the title in the first place. Good story, loving it.
