Master Bismuth was really starting to regret something. When Abel was trying to fix that magic sword, he was just standing far away to watch him do it. He was just watching because he thought that it would be funny to watch a wizard fail at it, but really, he should've gone closer and paid more attention.
And the way Abel fixed it. He had never heard of this technique before. If Bismuth had to guess, it was probably a secret technique that could've come from literally anywhere--ancient ruins, heritage from certain races; It could even be a new invention. Whatever the case was, this was the first time he had ever seen someone fix a magic weapon like this.
Master Bismuth was a master blacksmith. He had his fair share of knowledge. Still, despite all his years of experience, he had never seen anybody fix a magic weapon with just a few hits. Whatever Abel did, it was completely different from what he was familiar with.
