Wei Wuyin sat cross-legged, his eyes focused on the pages of a particular book. It was titled: "Transformative Theory of Essence & Energy."

Extraction, Growth, Containment, Refinement, Creation, Transformation, and Fusion.

The difficulty of even understanding them to an elementary level was immense, and it was these profound theories, principles, and broad profound concepts that gated many Alchemists.
