Yan Chuan took the silk scroll, held the brush and painted, the tip gliding smoothly, filling the long scroll with images of nude women, either standing or reclining, some showing their front, others their back. The faces of the figures were all similar, but their expressions varied from joy to sorrow, to affectionate glances, and gentle anger. There were a total of thirty-six images, each annotated with colored lines indicating the acupoint positions and cultivation techniques.
After that, numerous footprints were drawn, marked with words like "Women" and "No Mistake," all positions from the "Book of Changes."
The footprints were densely packed, perhaps thousands, connected by green lines from one to another, with arrows illustrated on the lines.
"Mysterious stepping technique, preserve oneself, avoid the enemy, accumulate inner strength, then take the enemy's life."
Yan Chuan wrote "Lingbo Weibu" with a smile: "This Qinggong is more than just Qinggong!"
