In the venue of the Mingyue Society, Misumi Mikoto was showing Chen Yu the progress she had made in her studies during this period.
As Chen Yu's disciple, although so far she had only learned the basics of meditation and the Spiritual Communication Ritual, for a novice apprentice, just these two were enough for her to practice.
The progress check for the Meditation Technique was very simple, having Misumi Mikoto start meditation without any assistance, and seeing the best level she could achieve was sufficient.
As the foundation of learning spells, the Meditation Technique is indeed very important, but the basic Meditation Technique primarily serves to train perception and get apprentices accustomed to meditation, laying the groundwork for later specializing in specific meditation techniques.
