For the following two days, Musashi and his team were immersed in using the balloon experience cards. In order to boost efficiency, they even hung balloons on their dormitory beds to practice whenever they wished. Regarding mind power, practice makes perfect. They needed to repeatedly experiment and find their own unique key and pathways.
In this area, Musashi didn't have any advantage. The training of ancient martial families primarily focused on the body and foundational skills. When it came to mind power, they were more concerned with persistent will. They had significant advantages in defending against mental attacks, but in terms of attack, they were not different from people like Marlon. Due to their previous "perseverance", they also lacked flexibility. Unexpectedly, Musashi was the one facing the most difficulties.
