Mc is extremely naive, for his age when he transmigrated. The power system is a small mess. Author is trying to merge the witcher, knight, and wizard system into 1 for a unique power system for the novel. But doesnt explain it well, making it seem like a mess. The cheat of the mc doesnt have ground rules or it isnt explained. Different techniques cost different amounts to upgrade is fine, but tell me why not just state a random number that you feel like it works for the amount of point the mc has. Ex. This technique costs 5 points to get to lv5 from lv1... Or this technique costs 8 point to get to lv5 from lv1... No standard in points just a random number, it doesnt scale with difficulty of the technique. Also the mc can just casually merge similar techniques like its abc making the power system of the world seem like a joke. Ex. He merges 6ish health preserving techniques into 1 allowing him to live up to 150+ years. And it only take 5 point to reach lv5 even though its extremely difficult, so difficult that the rest of the world cant do it. And he take a few hours to make this amazing technique.
