Primordial

Ryu sank into a state of meditation, entering Breath of Earth with ease. 

He focused all his senses onto his meridians, paving out every pathway with his Spiritual Sense and imprinting it onto his mind. 

In truth, this was the first time Ryu had spent so much effort focusing on his Chaotic Silk Merdians. As an Ancestral Grade set of Meridians, Ryu had believed that his own had been researched as thoroughly as possible. 

In Ryu's previous views, unlike other specialty Meridians which had their own unique quirks and unexpected abilities, his own were only known for their sturdiness and low density. There shouldn't have been anything else to study. 

But, who would have thought that the secret of the Chaotic Silk Meridians could only be unearthed by someone crazy enough to ignore the conventional path of cultivation? Beyond that, had Ryu not gotten his Realm Heart, he might have never seen the truth of the matter.
