The powerful magicians he met like Chalice could probably kill Miya with a snap of his fingers, but this same person couldn't do what Miya has done. It says a lot about how unique this Soul Art was.

'I see. This fully made sense. If automatons can do what the Mana Technicians can do, then there wouldn't be any human fabricators around.' Wallace said in his mind. It must be remembered how difficult it can to be a magic engineer. Most students that couldn't pass would have to work in a factory and fabricate Mana Artifacts for a living. If automatons can do the same thing then there might be a different level of civilization of this world. The world might be filled with automatons working non-stop. It would be a lot scarier.
Wallace sighed looking at the report about the successful fabrication.
