This technology that comes close to an entire alchemy industry chain is unlikely to be created by dwarves who haven't even established their own kingdom.
Kael looked up at the Alchemy Furnace and began to suspect that it was an artifact the dwarves had "archeologically" discovered from the relics of a previous civilization.
After all, the vast continent was the burial ground of numerous civilizations, and to a large extent, it was easier for an emerging civilization to thrive on the remnants of an ancient civilization rather than developing independently.
Whether it was the former Supreme Forest, or the subsequent Sacred Briania and Yibel Federation, all had absorbed some remnants of ancient civilizations.
If the dwarves were lucky, it wasn't impossible for them to stumble upon the relics of a former advanced civilization, not to mention that if a historical-echoing Dungeon was breached, they could dredge up quite a few technological artifacts.
