Normally, when Lind condensed a Mystery, he was a wash with power flowing down his meridians and spreading from his dantian outward into his body. WIth it came an almost instinctive knowledge of the concepts being incorporated into the Mystery he formed in the layer.
The Qi Mystery, however, did not just condense into its layer. The multi-colored material in his dantian began to branch out not only to fill the layer but also to go back to his previous layers. It enhanced them, or he thought it did.
Rather than change the previous layers, it was as if the 5 previous layers had been waiting for the Qi Mystery to appear!
Qi had no beginning or end, only the cycle.
The words flowed into him more deeply and made sense to him. All of cultivation came back to Qi. Without it, even Body Refining was impossible. The specific moves and repetitions of sequences sped up the absorption of Qi into the flesh and blood of a cultivator.
