Ves put down his work and took a long and relaxing break in order to recover his mental strength. His Spirituality recovered far slower than usual due to the continued presence of Qilanxo's spiritual fragment in his mental and spiritual space.
He described the sensation as hosting a power reactor in his home. While the fragment did its best to keep itself contained, the residual energy leaking out from was incredibly hot and corrosive to his mind. Its spiritual quality and quantity was far above what Ves could muster on his own.
His mind simply wasn't acclimated to this degree of spiritual strength!
Therefore, ever since he woke up after that fateful experiment, he felt as if his mind was constantly being strained. While this burden debilitated him enormously at first, he slowly acclimated himself to the effects.
