Jeming ultimately didn't choose those body strengthening techniques that seemed grandiose by name, but instead opted for a rather ordinary one.
"Charles' Body Element Refining Technique."
This is the body strengthening technique Jeming purchased from the Magic Net.
This body strengthening technique is a very foundational type of body element refining technique, with an extremely ancient origin, even considered outdated.
Essentially, modern wizards no longer use this technique; there are countless improved element refining techniques available.
However, despite being somewhat outdated, Charles' Body Element Refining Technique actually laid the technical groundwork for many element refining techniques, and it could be said that more than half of them were improvements from this technique.
The most important thing is that due to its foundational nature, there is a lot of related research.
