Growing Products
The idea of 'creating' complicated spiritual constructs and products via growth rather than fabrication and assembly was perhaps the most radical and innovative idea he came up with! Its potential was enormous as it allowed him to sidestep the more traditional development path of spiritual engineering!
Certainly, what Ves imagined as 'traditional' spiritual engineering was incredibly powerful and versatile. Though the requirements were very difficult to meet, once someone became a master at spiritual engineering, they could produce any spiritual product imaginable with complete understanding how it worked because they understood and controlled every single detail.
This was what Ves yearned to achieve himself. As a mech designer, he always pursued this aspiration, and with the help of the Skills bought from the System, he had become very proficient in the finer details of mech design.
