Zhenwu judges realms by the flow of True Qi.
If the True Qi wanders inside the body like silk, it is called Qi silk.
And when True Qi flows like a stream within the body, it is called Qi Stream.
After that, there are two more realms: Qi River and Qi Sea.
After Qi Sea, comes True Qi External Release, which is like a tiny universe that can burst forth with terrifying power.
As for reaching the state Du Mao once had, turning True Qi External Release into small arrow-like projectiles that puncture falling snowflakes around him, that is a more delicate control of the True Qi External Release once one reaches the Kingly Aura realm.
Miss Ruan is basically at the entry-level amongst martial artists, a strong one within the beginners.
