[Ephemeral Tapestry] wasn't a technique, it was a mutation of Ryu's Mysteries of Heaven and Earth Pupils that he had unlocked while cultivating a Heaven Grade technique.
Of course, the Heaven Grade technique was utterly useless now. It was impressive back then, but it couldn't hold any weight. In addition, it was just the trigger of the mutation, not the foundation of it.
If Ryu was correct, he was fairly certain that this mutation wasn't really a result of the Heaven Grade technique itself, but rather his Bone Structure. Or, rather, his former Bone Structure.
[Ephemeral Tapestry] painted the world in vivid color before Ryu's eyes. With it, qi was no longer some invisible entity he had to rely on his soul to sense, but was rather real and tangible.
