Chapter 137: You two remain

Cain spent the next two weeks wholly committed to his cultivation. He focused on three main factors, his Fiend Devourer Cultivation Technique, the Blood Refinement Art, and his Hypnosis Master training.

His Wave Cultivation was the most important since it was the core of his battle strength and had an essential role in everything else. The higher his cultivation, the easier it would be to train the Blood Refinement Art. It would also improve his willpower, enhancing his Ego Eternal Path of Power and Hypnosis Master's skills. 

Although the Blood Refinement Art was just an auxiliary technique, and his cultivation base limited its growth, it was fundamental in allowing his body to show all of Cain's abilities. Without the body enhancement granted by the art, Cain's body could not endure a 2000% Wave Burst or its Asura Form.
