William was planning to teach her a mobility-based technique, something to help her evade any incoming attack. During the past battles, she was always struggling with incoming attacks, and had to stay on the side of others to get safe.
"Not a bad idea," yet when he thought back to how poorly she did against stronger enemies, he decided to teach her this, "but this technique won't show its real value before heading into the gold grade…"
"Pft, as if I didn't get there before," she confidently said, before laughing out of her excitement, "teach it to me, teach it to me…" she held his arm and kept swinging it right and left, making him unable to control his laughs anymore.
"Alright, memorise the incantations first…" he started to teach her the technique, while his mind was diverted towards something different.
All this time he had to use either old techniques that were commonly used for other masters, or the Holy Sword one that he developed a long time ago.
