A wave of fear slammed into his soul like a hammer was used to slam a nail into a piece of wood.
The feeling was intense and extremely painful.
Of course, he couldn't feel any physical or external pain but it felt like Sara's spiritual fear energy had attacked his soul directly, causing his heart to lurch and his lungs to tighten.
His entire body shivered violently and Aster was slowly finding it difficult to breathe as he repeatedly clawed at the air like he was currently drowning in a deep lake.
"S-Sara…?" Aster continued to make agonizing gurgling sounds but his banshee maid didn't answer.
Her hands trembled a bit but Sara made sure that her eyes remained fixed on him.
She internally reminded herself that she shouldn't stop this yet, because the unbearable surge of terror Aster was currently feeling, was exactly what he needed to awaken the Fear Branch of his spirit root.
