After Duke finished the Magic Basic Theory class, he had a basic approach and direction for learning magic.
A day's course couldn't cover much content, but it allowed Duke to grasp the contents of the Magic Basic Theory more quickly.
Once he thoroughly understood this set of content, self-learning other magic would be much easier, at least with a basic methodology and theoretical foundation.
After Duke mastered the Wizard's Mark, the first person he wanted to contact was naturally Vivian.
However, if you want to record another wizard's mark, it must be exchanged face-to-face, which is a bit troublesome.
Duke thought about it and decided to write a letter to the Thorn Holy Tower to inform Vivian of this matter.
There is a place on Academy Island to send and receive letters; they don't deliver letters, so you need to inquire if there is any for you.
