The technique itself was actually very simple to use. Its only requirement was for Shun Long to circulate his qi according to its method during intercourse, and his Yang essence would be automatically absorbed by Liu Mei's Yin essence, while he would also absorb her Yin essence at the same time.
The sound of Shun Long's hips meeting Liu Mei's butt, resounded throughout the room, mixed with the moans of pleasure and excitement that they were experiencing for the first time.
Suddenly, Shun Long felt his body and mind reaching the peak of their pleasure limits, before he felt a kind of warm energy leaving his body, as it slowly filled Liu Mei.
At the same time, Liu Mei felt the energy inside her body growing, as it fused with Shun Long's warm energy, growing stronger and stronger, before a similar kind of energy left Liu Mei's body, heading towards Shun Long's.
Shun Long felt his body getting rejuvenated, as Liu Mei's yin energy was fusing with his Yang.
