Over the last month, Mira and Maria were busier than they had ever been before. Not only did they practice the various applications of Qi, Qi Control, and techniques, but they also learned the Hidden World Technique from Hana.
Thanks to Mira's enhanced brain functions and comprehensive abilities, she didn't need to sit down and only focus on practicing one thing. She could practice her Qi Applications, Control, Techniques, and Hidden World simultaneously. Though typically, if she wanted to refine her Qi Control, she could only do it in tandem with her Hidden World practice sessions.
Maria didn't have the same comprehensive abilities as Mira, but they were slightly enhanced after breaking through to the Core Formation Realm.
Mira mainly used Maria as her punching bag over the last month to test her progress, and because of that, Maria also learned and improved rapidly.
