“True, why didn’t I think of that?” Sola said with a thoughtful face before adding, “it is supposed to heal actually, it is supposed to heal any wound on spot.” She stated and Kurtz face slowly turned grim. 


“Is it, we might need to find some wounded Demon then.” He quickly suggested. 


“But you are my test subject not some wounded Demon, why don’t you find another method, involving you.” Sola replied and Kurtz face hardened.
