While grinding his teeth against each other out of simple annoyance, Eisen continued to work on what he wanted to do before. After all, he had no idea how he was supposed to respond to what he was just told.
He was supposed to keep everything like Medieval Europe? What the hell was that supposed to mean? Eisen really, really had no idea what was going on, but for now, he wanted to just ignore everything and keep crafting. This world was the only place where he could do that now, and if there was anything threatening that, he would spend as much time creating things as he possibly could.
For now, the old man grabbed another material that he wanted to play around with, the Spatial Gem. There were a whole bunch of them in the Material Storage, so this was the best chance for Eisen to do just that without any hesitation.
