"Dragon Yang Body Refining Technique?"
[Yes, otherwise how could the Innate Fire Treasure Qi in your body have advanced?]
"What I practice is the Daoist Crotch Skills. When perfected, it forms an Immaculate Golden Core, and when these two combine, they advance."
[It seems this Hard Qi Gong has borrowed a lot from the Dragon Yang Body Refining Technique.]
"Aren't Qi Refiners all just focusing on Qi Collection for cultivation?"
[Yes, practicing Iron Shield Skill is to collect the "Innate Kidney Essence Qi" inside your body.]
"Innate Pure Yang Qi."
[Different names, same essence. Martial Arts originally derived from the methods of the Four Sects. The Qi mentioned by Qi Refiners not only exists in the heavens and treasures but also in the human body. The kidney, belonging to the water element of the Five Elements, transforms this Innate Kidney Essence Qi through the body's Five Elements conversion, balancing Yin and Yang, and ultimately transforming into the so-called "Yang Qi".]
