Chen Shaowei, a Taoist priest in Heng Yue in the Tang Dynasty, wrote it between Xuanzong's congenital and Kaiyuan years. New Tang book? Yi wrote a volume of this book. According to the preface before the author published the book, the original book includes three parts, namely preface, seven chapters of Lingsha (seven chapters) and then formula (two chapters). There are two kinds of books in the orthodox Taoist collection today, one is the trick of refining the true treasure in the cave and the other is the trick of refining the true treasure in the cave for nine times, both of which are included in the laws of the cave god department. Volumes 68 and 69 of the Seven Signs of Cloud are also included in this book, which are called Chapter II of Nine Returns to Then and Theory of Seven Returns to Lingsha. The preface of the original book first summarizes the name of Qigui Cinnabar. It is said that "cinnabar is the essence of the sun and the body of golden fire"; It is made of the essence of golden fire, which is the foundation of returning to Dan and the root of great doctors. There are many kinds of cinnabar, but only Guangming sand, Baima tooth sand and Zi Ling sand are the "best medicines". Repeated refining of cinnabar for seven times is called "seven times", and silver, yellow silver, blue gold, gold, red gold, red gold and purple gold can be refined respectively. Zijin is transformed by the seven-owned Lingsha, "enough to contain the gas of Yang Zhenyuan". Then turn Zijin into sand and burn it for a week, that is, turn Zijin into Dan, and you can take it easily. It can also be used to convert mercury, lead, tin, copper and iron into gold. The book Lingsha Qigui describes the dosage, temperature, flight, prompt, taking method and effect of alchemy sand from one to seven. There are also two chapters on "then to tactics", which are about the essentials of pumping sand to smelt mercury.
The unique trick of refining the true treasure in the Great Cave and returning it to the elixir through the Nine Classics was originally an article in the Classic of Refining the True Treasure in the Great Cave. The orthodox Taoist collection was divided into a single volume and included in the various arts of the Cave God Department. This paper is divided into two chapters, namely "including evidence" and "Zhang". In the second chapter, it is divided into nine categories. The first three chapters talked about the methods of extracting mercury from sand, adding gold to smelting mercury, and combining medicine with repairing gold. They also talked about the sources and characteristics of manjianghong, Zengqing, Xuan Ying, fossils, halite and mirabilite. The middle three products illustrate the flexibility of five-stone gold, four-yellow volt system and Yang gold. It is said that gold, silver, copper, iron, and lead (tin) hardware are all vicious, and they all hurt the bones and promote life and death. Four yellows (namely, realgar, orpiment, arsenic and sulfur) must be used in smelting, and the metal material must be changed into positive gold (cinnabar) before the positive gold can be refined into Dan. Finally, use three words to reconcile the big Dan, the furnace tripod and the alchemy to prove the truth. It is said that taking Dan according to law is to soar to reality.
