In the end, Eli took the mechanical box away under Vivika's insistence.
After taking it away, he studied it for a while and found that the locks on the mechanical box were indeed quite interesting. They were of the first, second, and third circle levels. As long as one was skilled enough, they could be opened.
In fact, this was similar to potioneering. The mage world once had another sub-class called mechanical mages. They focused purely on mechanical knowledge and mechanical refining. There were also differences in level, and they were also distributed according to circles.
Currently, Eli should be a third-circle pharmacologist and a zero-circle mechanic, and this was because he had obtained alchemy knowledge in the secret plane, which also had the effect of drawing parallels from inference.
After studying it for a few days, Eli finally gave up and decided to wait for the knowledge from the black Isotta to arrive.
