Lian jing hua qi 煉精化氣

"Refining essence into energy". The first of the three alchemical transformations, classically allotted a hundred days and worked in the lower dan tien. Mo Pai's entire published curriculum — levels 1 to 4 — sits inside it. The two that follow are lian qi hua shen (煉氣化神) and lian shen huan xu (煉神還虛).
