Apollo waited until the evening when Master Aaron was feeling well and ready to teach him swordsmanship. They headed to the villa's backyard, which offered ample space for his training.
"Are you ready?" Master Aaron asked.
"Yes," Apollo replied eagerly, having waited for this moment.
Master Aaron nodded and began his teaching.
"Before I teach you my swordsmanship, you must first understand something crucial that lies at the core of every sword technique, unlocking its true power."
"What is it?" Apollo asked, unable to contain his curiosity.
"Sword Aura," Master Aaron replied with a mysterious smile, revealing the secret every aspiring swordsman must grasp to become a truly skilled swordsman.
"Sword Aura!"
"What is that?" Apollo asked, hearing about it for the first time, as no one had ever mentioned it before, and he had found nothing about it in books.
