Hearing Shangguan Ruyun's answer, Chen Hui took a look at Zhou qiuchu, because Chen Hui understood Zhou qiuchu's idea of asking this question.

If it's just a legend, the legend of alchemy and the legend of the Danding sect will only exaggerate, and it's supernatural, not concrete.

But if the legend is specific, such as the question asked by Shangguan Ruyun, what kind of pills are made by the Dan Ding sect, this is a specific question.

If there is a legend, it means that it is likely to be true. If there is no relevant legend, it is not credible to a great extent.

Shangguan Ruyun's reply clearly shows that the legend of Dan Ding sect's alchemy is quite detailed.

However, after saying this, Shangguan Ruyun pondered for a while, and then continued to say: "even for these two kinds of pills, there are more detailed legends. The legend I heard is that the Qi tonifying pill is yellow, while the cultivation pills for improving cultivation are different in color. The best cultivation pill is purple!"

After Shangguan Ruyun said this, Chen Hui took another look at Zhou qiuchu.

Shangguan Ruyun smiles, and then says: "legends are mostly supernatural things. However, these legends about the Danding sect are more detailed. Although I have never seen the existence of the Danding sect, I prefer that the Danding sect really existed."

"There is no accurate record of the time of the disappearance of the Danding sect. If there is any record, it will not be called a legend." Shangguan Ruyun continued: "however, there are records of alchemy in Taoist classics, but these records are definitely not records of the Danding school."

"These records are the records of those ancient alchemists refining pills." Chen Hui nodded and said, "Dan refers to cinnabar, or mercuric sulfide. It is an inorganic compound of sulfur and mercury (mercury). Because it is red, it is also called cinnabar."

"The ancients' cognition is much less than that of modern people. In their view, red sand is different from vegetation. It is not only burned but not burned out, but also" the longer it burns, the better the change. " Chen Hui shook his head and said: "the mercury produced by the cinnabar mercury is a metallic substance, but it is in a liquid state. It has the luster of metal and is different from the shape and quality of gold, silver, copper, iron and tin. Therefore, it is described as stubborn and stagnant in shape and quality in eight words."

Ye Mengchen said at this time: "because of its pharmacological effect and physical and chemical properties, the ancient alchemists used it as the main material for alchemy. Its shape was round and flowing, and it was easy to volatilize. The ancients felt very magical, so they chose other gold and stone drugs to mix with liquid mercury (mercury) and burn each other according to a certain formula, and repeatedly carried out reduction and oxidation experiments, The so-called elixir of immortality is actually the earliest chemical reaction product of human beings. "

Alchemists decompose mercury (mercury) after heating the cinnabar, and then find that mercury (mercury) combines with sulfide to form black mercuric sulfide, which is sublimated by heating, and then returns to the original state of red mercuric sulfide.

In fact, it is a chemical reaction of reduction and oxidation to make mercury from cinnabar and reduce cinnabar by sulfuration.

"Modern people all know that Mercury is poisonous. Pills made from mercury must be poisonous!" Chen Hui said with a smile: "however, the ancients didn't know. They just thought mercury was magical. Alchemists mistook it for Alchemy to make the elixir of immortality. In fact, I wonder if the elixir of immortality made by these alchemists in ancient times is similar to the modern addictive thing?"

"I agree with you." Zhou qiuchu said with a smile: "if you can be an emperor, how can your IQ be online? Even if their intelligence quotient is not higher than that of ordinary people, they have to be the same as ordinary people. If they eat these so-called elixirs of immortality, if they have no effect, they must cut off the heads of these alchemists. They not only don't cut off their heads, but also insist on taking them. It is estimated that they are addicted to them. After taking them, they feel like immortals and think they are going to become immortals! "

Shangguan Ruyun naturally knows what Chen Hui said. He laughs and doesn't say much. This kind of thing only appears in modern times. Shangguan Ruyun knows it. It has to be said that Chen Hui's analysis is very reasonable. If the ancient emperors took these pills, they would think that the elixir of immortality is fake, They will cut off the alchemists' heads.

There are even many historical records that the emperor who pursued to take the elixir of immortality would be as thin as a log and pale in the later period. Although there is a cause of mercury poisoning, this kind of symptom is very consistent with the appearance of modern addicts taking that kind of thing for a long time.

"It is recorded that the emperor who took the elixir pill must be after the Dan Ding sect." Shangguan Ruyun said at this time: "although the Dan Ding sect is a legend, the legend itself means that it is a very long time ago. The reason why we people in practice don't take charge of the emperor to take the elixir of immortality is that the rules of the practice world don't become, and the alchemists and Taoists who refine the elixir of immortality are not people in practice at all, How is it possible to make genuine pills? "

Shangguan Ruyun has made it very clear that there are a large proportion of alchemists and Taoists entering the practice world. However, not all alchemists are people in practice, and there are also ordinary Taoists.

"And this bronze tripod?" Chen Hui pointed to the bronze tripod and said, "don't you think it's a magic weapon for alchemy?"

"The Danding sect is a legend, and the pills of the Danding sect are also legends." Shangguan Ruyun said with a smile: "similarly, it's also a legend that how the Danding sect makes pills. However, since it's said that the Danding sect can make pills against heaven, it doesn't make sense to make pills without magic weapons!"

"The alchemists and Taoists who made alchemy for the emperor used alchemy furnaces!" Shangguan Ruyun said: "if there is a Dan Ding sect in the practice world, it will not use a Dan furnace to make pills. How can ordinary wood or coal make pills of the Dan Ding sect? You know, although there are various legends about the Danding sect, there is never a legend that people in practice took the pills of the Danding sect, but there was a problem. "

"Does the bronze tripod have another function, for sacrifice?" Chen Hui said with a smile: "can't it be the magic weapon of sacrifice?"

"In practice, people are meant to become immortals in order to gain the Tao, and rise by the day!" Shangguan Ruyun asked: "I want to be an immortal. Who do you think I will sacrifice to? What kind of gods can you communicate with with? What's good for communication? "

"What do you mean, are you atheists in practice?" Chen Hui asked with a smile.
