"Try to feel the energy inside your body," Michael advised.
Right now, William was sitting in a private guild training hall, trying to improve his aura manipulation with Michael helping him out.
The mission they had taken didn't start until three more days.
While William wanted to rest today due to his body still having accumulated fatigue from his time in Zunesha village that he had forgotten about, Zephyr strongly advised him to work on his aura manipulation.
While William didn't remember it, Zephyr clearly remembered how William almost got killed by an aura master.
And he wanted to prevent a similar scenario in the future, so he advised him to ask Michael to finally take his responsibility as his master seriously and teach him about aura.
While Rex had taught him the basics of aura and what it was, he hadn't spent enough time yet to teach him to use the power.
