An alchemist is divided into an external alchemist and an internal alchemist. External alchemy originated from pre-Qin alchemy, that is, burning minerals in an alchemy furnace to make "elixir"! Later, I planned to make the human body into a furnace tripod to practice the essence, which was called internal alchemy. External alchemy refers to Taoism burning alchemy medicine through various secret methods, or directly taking some Cao Zhi to touch its own yin and turn it into yang; Chen Shidao's note: "Taoism takes boiling stone as its external medicine;" Dragon and tiger miscarried, spit out the old and take the new as the inner Dan.

This thing is a good thing, and you can live forever after eating it!

External alchemy refers to Taoism burning alchemy medicine through various secret methods, or directly taking some Cao Zhi to touch its own yin and turn it into yang. In addition, Taoist elixir can also refer to "clearing the spirit in the void". External alchemy can also refer to alchemy or Taoist spells such as Fuyong and Leifa.
