Chapter 1770 - Chapter 1705: Dragon Gate Archives_3

After the establishment of Taoism, the alchemical knowledge of the Square Immortal Technique was inherited by Taoists and gradually developed into a secretive alchemy practice. The Taoist alchemist Ge Hong compiled the complete works of External Alchemy Skills in the book "Baopuzi," classifying external elixirs into three kinds: Divine Pill, Gold Liquid, and Gold. This practice flourished during the Tang Dynasty, forming a societal trend of consuming external elixirs. However, many elixirs from external alchemy contained mercury, which is toxic to the human body, leading to its decline after the Song Dynasty. Dragon Gate remains one of the few extant External Alchemy Sects to this day.
