บท 75: Pillar of Mind (I)

"You went through marrow washing?" Cain did not hide his amazement as he realized Levi's accomplishment.

What Cain referred to as marrow washing was a process in which a Wave Warrior expelled the body's impurities. Not just that accumulated in the skin but those that reach the marrow. It was an excruciating process but also a tremendous lucky chance, especially for Astral Wave Warriors.

Astral Wave Cultivators need to pay special focus to their foundation, and in the Wave Warrior rank, marrow washing played an essential part in it. 

"Hahaha, that is right. I entered Level 3 yesterday during the night, and that rush of Astral Wave running through my body allowed me to go through marrow washing." Levi's face showed immense pride as he uttered those words. It made sense; after all, the sooner you begin to experience marrow washing, the greater your future cultivation prospects will be.
