Jiro fighters directed all the members of the Sky Force to do breathing exercises, they were all cross-legged and lined up in 7 rows and 3 backwards with a distance of about 2 meters per person.
Jiro wants to teach concentration in regulating the energy that comes out of their bodies. If they see potential, they can absorb natural energy quickly, which is one with nature. Then, Jiro will give a special direction for them.
All the members of the Sky force amazed Jiro, how could they not all even have different classifications in terms of special abilities. However, they were all able to manipulate their internal energy albeit to a different degree.
An example is the Chairman Yarko who is a warrior who wields a sword. Sword wielders like Yarko's leader were mentioned by Jiro as having early rank 9 warrior abilities. Even so, the leader of Yarko also studied magic and circle power, in mage he was rank 5.
