Reiger's speculation was not without foundation.
The Total Concentration Breathing technique already had the effect of enhancing physical abilities, but it only strengthened the cardiopulmonary capacity, speeding up blood flow to indirectly increase the body's vitality and physical capabilities.
In the Akasha continent, breathing techniques aided in cultivating skills, activating Magic Power, and revitalizing the body, allowing the body to grow holistically by absorbing Magic Power. If this principle could be integrated into Total Concentration Breathing, then it was not impossible to expand the enhancement scope of Total Concentration Breathing to all aspects of the body.
