Huang Ye continued his refining process. After purification, he felt a qualitative leap in his strength. If the refining was successful, his power would increase even further.
The refining in the Initial Yang Realm involves continuously compressing spiritual energy. By the time one reaches the Primordial Yang Realm, this highly compressed spiritual energy transforms into a liquid state.
Huang Ye thought this process was somewhat similar to the three states of matter in physics.
Refining is a process of increasing density, continuously compressing elements, making the gaps smaller and smaller until they form a liquid state.
