The Golden Core cultivated through the "Qu Kan and Fill Li" technique is also known as the "Dragon and Tiger Golden Core." It is a comprehensive technique incorporating various Golden Core methods such as "Water and Fire Reciprocity" and "Lead and Mercury Golden Core," making it relatively easy to practice.
The key to this technique lies in using the [Water Gold·True Yang Qi] hidden in one's Kidney Water from the Kan position, injecting it into the Heart's Li Fire to purify the [Li Center Yin], thereby achieving a strand of [Pure Yang Gold] as the foundation of the Golden Core.
Thus, replacing the so-called Heaven-gifted Immortal Golden Nature with the [Pure Yang Gold] born from the cultivator's "Heart" and "Kidney," the Golden Core achieved becomes truly one's own.
