After a while, the alchemy room was full of people.

"Are you talking about this little guy?" said a kind white-haired old man looking at Long Xia.

"Yes. Long Haiwen replied, and then said to Long Xia, "This is Longxi Hong Ancestor, a Dan Saint. ”

Long Xia hurriedly saluted the old man: "Junior Long Xia has seen Xihong Ancestor. ”

Long Haiwen introduced others to Long Xia, and Long Xia saluted one by one. Everyone was very satisfied with Long Xia's words and deeds, only Long Xiaoxiao was squinting angrily, puffing out his anger and pouting again.

"Then let's get started, Haven, you prepare the pills and herbs for him. Long Xihong said.

Long Haiwen took a pill and handed it to Long Xia, and then went to prepare the medicinal materials.

Long Xia saw that the pill was written on the "Exploding Yuan Pill", and there was also the effect of the pill in the back: it can restore a large amount of vitality for the martial artists of the Hetian Realm and the Breaking Heaven Realm, and the amount of Dan used is also different due to different realms, and it can restore the full vitality once and twice, and there are no side effects once or twice; it should not be used many times, otherwise the talent will be ruined. The following is also a list of the medicinal materials used and the order of refining.

After Long Haiwen finished preparing the medicinal materials, Long Xia began to refine the pills. The eight-pin pill has been refined before, but it has not been refined, and the exploding pill belongs to the extremely difficult pill to refine among the eight grades, and generally only the alchemists of the eight-rank stage can refine it.

Long Xia started to warm the furnace, then threw several medicinal materials into the Dan Lian and covered the furnace lid to start smelting, and after a while, Long Xia took back the Dan Fire and stopped smelting. Long Xia took out one of his own Dan furnaces, started the furnace again, and then threw four kinds of medicinal materials into it, covered the Dan furnace and began to smelt, and after a while, Long Xia withdrew the Dan fire and stopped smelting. Long Xia took out another Dan furnace and started the previous method again.

Everyone didn't know why, they had never seen such alchemy. Usually, alchemy is to put one medicine after another into the Dan furnace, slowly smelting, fusion, fire control, refining and other steps. Although everyone had doubts in their hearts, out of the quality of an alchemist, they did not interrupt Long Xia and watched quietly.

Two hours later, there were already seven Dan furnaces in front of Long Xia, and at this time, there were still two medicinal materials left that had not yet been used. Long Xia opened the lids of the two Dan furnaces, poured the liquid of one of the Dan furnaces into the other Dan furnace, and then repeated the previous smelting technique. Next, Long Xia mixed the remaining five Dan furnaces with two furnaces and three furnaces for smelting. Therefore, in the end, there were three Dan furnaces with medicinal liquid, and everyone watched, and there was a trace of enlightenment in their minds. Long Xia did not stop, and poured the medicinal liquid from the two Dan furnaces together to smelt it, and after a while, Long Xia opened the lid of the furnace and poured the third furnace liquid into it as well. The Seven Furnaces have started the real alchemy process, but this is no longer important, because in the previous steps, there is no longer a need to fuse and refine, and now there are only a few required pill ingredients in the Dan Furnace, as long as the medicinal liquid is evaporated, and then the Ning Dan is enough.

An hour later, Long Xia withdrew the Dan Fire and meditated cross-legged to recover. Long Haiwen walked over and slapped the lid of the furnace with one palm, and a burst of Dan incense wafted out of the Dan furnace, which soon overflowed the entire alchemy room.

"Five, first class. Long Haiwen said excitedly.

"Five, first-class pills?" everyone showed surprised expressions, just now they smelled the danxiang, everyone already knew that the pill had been made, but they didn't expect that it was five first-class quality pills, even if they did, few of them could refine them.

Long Xihong and a few Dan Saints walked over, and after glancing at the Dan furnace, they said, "It is indeed a first-class product. ”

Everyone waited with solemn expressions for Long Xia to resume his meditation. After about half an hour, Long Xia felt that his vitality had recovered, so he ended his meditation and stood up.

Long Xihong stepped forward to salute Long Xia, this is a respect for Long Xia Dandao's talent, although Long Xia has not yet reached his own level, but in time, he will definitely surpass himself, no matter how he alchemizes, only look at the result and not the process. Then he said, "Divine Son, do you have anything to say about your alchemy method?"

Long Xia thought for a moment and said, "My alchemy is based on chemical knowledge, or on the basis of a pharmacist. Traditional alchemists' understanding of medicinal materials is basically pharmacology and medicinal properties. In addition to these two, I also pay special attention to the ingredients of the medicine, that is, what substances each herb is composed of, which substance of the medicine is needed to refine each elixir, and whether other medicinal materials also have this substance, which can be substituted for each other. There is a sequence of fusion reactions of these substances, and everyone understands it. However, traditional alchemists basically refine based on experience, and have no understanding of various constituent substances, just like the air we breathe, we only know that it is air, an invisible substance, but we don't know that air is not the only body, it is composed of oxygen, nitrogen, helium, argon and other gases (these gases are all said by Long Xia himself, because the Hanging Universe Continent does not divide gases, everyone naturally does not understand, only know the name of each gaseous substance). In the same way, the same is true for each medicinal material, we only need to symbolize each substance, and through the fusion reaction, find its source and destination, and form a reaction formula. ”

Everyone fell into the fog, as if they understood but did not understand. Long Xia knew that although these people were smart, it was still very difficult for them to accept a new idea of alchemy, so he took out the "Chemistry and Alchemy" he wrote and handed it to Long Xihong. Long Xihong took "Chemistry and Alchemy", and then opened it and watched it with a few old antiques.

Although a few old antiques are old, they are cultivators after all, and they can read them in about half an hour, and then meditate for half an hour, which is already clear to their chests.

"Haha, it's interesting, in this way, the various medicinal materials are much clearer, and the idea of the pill is clearer. An old antique said with a smile on his face.

"Yes, this so-called reaction formula is very helpful for us to study Dan Dao. Another old antique said with a smile.

Long Xihong also said excitedly to Long Xia, "Divine Son, can you let the other people in the Alchemy Pavilion watch it?"

Long Xia said nonchalantly, "They can transcribe at will." I wrote this book to read it to alchemists all over the world, hoping that there will be new developments in the alchemy world and become a pioneer in martial arts. ”

A few old antiques saluted Long Xia: "The Divine Son is really broad-minded!" They really sincerely admired, which alchemist has new insights and methods in the Dan Dao, and is willing to announce the world. A few old Gu Dong could foresee that in the near future, there would be great changes in the Dan Dao realm, and with it, the martial arts realm.

Traditional alchemy is all practiced by one person, and the method of Longxia allows alchemists to divide labor and cooperate.

After exchanging alchemy insights with a few old antiques, Long Xia and Long Xiaoyun left the Alchemy Pavilion.
