Firstly, lecturers who want to enroll students make magical items containing their spiritual will and spread them worldwide through trade and other means.
In the Tatis Empire, a lot of circulating magical items are made this way.
Secondly, people with higher "Spirit" attributes, after accidentally obtaining magical items, will study them.
Just by spending some time and mental effort, these people can decipher the knowledge within the magical items and, guided by that knowledge, establish a spiritual connection with the lecturer in the distant Ulnas Magic Ring.
Finally, after consolidating and maintaining the spiritual connection, lecturers establish regular "online classrooms." There are also mentors within each wizard force to provide on-site teaching and training tasks for wizard students.
The lecturer will teach the apprentice magical knowledge and instill their values through the spiritual connection.
