His days in Jerano were numbered, but Arthur was not in a rush to leave since it would draw attention to him if he suddenly left. The best method to leave without the seven families noticing him was to create a problem.
Arthur looked at the wandering scholars rushing to and fro as he walked through the research department. At one point, he was the same as them, seeking knowledge in the most inconspicuous corners of science for another rune on his list.
However, after he became a runesmith, all of his runes disappeared. There were no more runes that he needed to learn and no more lists of runes that he had. His ability as a runesmith became like a blacksmith, a wielder of runes instead of a welder.
It was safe to say that Arthur can replicate runes now, as long as their impact on the world did not exceed his mana or level. However, he was the same as a painter with unlimited colors at his disposal, but he still needed to create something out of them.
