บท 176: Laws and marrow washing

Cain had just reached his new residence and was ready to continue his experiments in Genetic Coding when a voice appeared in his head.

"Brat, it is me." Zarak's voice echoed inside Cain's mind as this one used his Ego Wave to communicate.

Cain was surprised to hear Zarak's voice and realized that this could stretch the Ego Wave for such a long distance. He was able to keep calm and wondered whether his master had questions about his actions during the last month. 

However, Zarak's question had nothing to do with that.

"Tell me, where did you get your body refinement auxiliary technique?"

Cain was a little confused by the question since Zarak already knew about the Blood Refinement Art, but this was the first time this one asked about it. Although he was not fond of revealing his secret, Zarak had shown him there could be trust between them, so he decided to tell the truth.
