"Golden Heavens Technique" had five layers of absolute mysteries, and with Fei Hong's current cultivation base, the first layer of absolute mysteries was enough. He slowly guided his true energy to develop the upper chakra and the meridians, and his upper body. It also strengthened his body systems exponentially to cope with the consumption of his life-essence caused by the "Golden Heavens Technique".
Through these months of practice, Fei Hong understood this set of procedures and used it smoothly. Ordinary cultivators really didn't dare to practice the "Golden Heavens Technique" which consumed a lot of body functions when practicing qi, developing the chakras and expanding the meridian channels. It was a common estimation that if one were to practice the technique once or twice, one would become a total waste.
