Jiang Ning, the alchemy room of the Lin family, is the first time to hear that the alchemy room is located in the deepest part of the green corridor in the southwest corner of the manor, which is covered by green vines all the year round.

Jiang Ning walked into the alchemy room, although the space inside was quite large, it was filled with a dazzling array of things, and it looked a little crowded, especially the alchemy furnace in the middle of the room, which was more than one meter in diameter and 2 meters high, and a thick pipe on the roof was connected to the alchemy furnace, thinking that it should be the smoke outlet of the alchemy furnace.

Lin Zhengyuan didn't know much about alchemy, so he left after taking Jiang Ning to the room, and then Li Tianyi greeted him.

"Little brother, is this the Dan Fang you gave to my junior brother?" Li Tianyi said and took out a piece of paper in his hand, which was the Dan Fang that Jiang Ning wrote to Lu Daochang on Yanling Mountain that day.

"Yes, does Daoist Li think there is something wrong?" Jiang Ning nodded and asked suspiciously.

Li Tianyi looked at Dan Fang with deep eyes, his brows couldn't help frowning, and Jiang Ning didn't bother silently, so he watched quietly from the side.

"This Danfang looks very peculiar, and it is the first time I have seen it, so I don't dare to comment on it, but there is something unreasonable in it. Li Tianyi stroked his gray beard, and then said to Jiang Ning.

"Where is it unreasonable? This pill recipe has been successfully refined by others, I shouldn't be mistaken. ”

Jiang Ning explained slightly, but he didn't mention the matter of the Heavenly Dome Continent, after all, this was his secret, and it was impossible to tell others easily.

"Is it true? Someone has really used this Dan recipe to refine it? But there are too many positive materials in this Dan formula, and there are only one or two negative materials, and it is difficult to achieve the harmony of yin and yang when it becomes a pill. ”

Li Tianyi looked at Jiang Ning suspiciously, and then under Jiang Ning's questioning, he explained the principle of alchemy to Jiang Ning.

Alchemy on Earth is divided into three steps, the first step is grinding, grinding the material into powder, the second step is refining, refining the essence of the material, and the third step is refining.

Alchemy pays attention to the harmony of yin and yang, some materials are positive, some materials are negative, and the materials with two attributes need to achieve a relative balance, so that they can become Dan in the last step of refining, if Yin and Yang are unbalanced, then when they become Dan, the materials will only be repulsed, even if they become pills in the end, it is only defective products, because the materials in the pills are not completely blended, but are forcibly kneaded together.

After listening to Li Tianyi's explanation, Jiang Ning realized that the alchemy of the Heavenly Dome Continent is different from that on the earth, and the alchemy of the Heavenly Dome Continent has only two steps, the first step is to directly extract the essence of the material, and this step is for the alchemist to directly wrap the material with spiritual power, and then put it on the fire to roast, and finally refine the spiritual liquid of the material.

In the second step of refining, all the spiritual liquid will be placed in the furnace of alchemy, and then the alchemist will use spiritual power to intervene in it, and control it with his own spiritual power, and finally become a pill.

When Jiang Ning tried alchemy, it was because when refining, it was difficult for the spiritual control to meet the requirements.

"Daochang Li, then according to your piece, how should this Dan Fang be modified?"

Jiang Ning knew that there could be nothing wrong with this pill, but after all, this was not in the Heavenly Dome Continent, since there was also alchemy on the earth, why not modify it according to the principle of alchemy on the earth, so that at least there was a chance of successful refining.

"Senior brother, go and get one money of sand ginseng, three money of jade bamboo, and half a money of dry lotus grass. ”

As soon as Li Tian spoke, Lu Daochang immediately turned around and went to the medicine cabinet to look for it, and after a while, he took the medicinal materials.

"Little brother, according to the old man's opinion, if you add these three flavored medicinal materials, the yin and yang properties of this pill can be reconciled to a certain extent, although it is not yet possible to balance yin and yang, but at least it can increase the probability of becoming a pill by two percent. Li Tianyi said to Jiang Ning.

"Then why don't you add a few more herbs to achieve a complete balance of yin and yang?"

Jiang Ning was a little puzzled, if the alchemy on the earth was so particular about the balance of yin and yang, then why not add more herbs.

"No, this pill is more special, adding these three flavors of medicinal materials is already the limit, if you add it again, I am afraid that it will destroy the efficacy of this pill, so the gains outweigh the losses. ”

After listening to Li Tianyi's explanation, Jiang Ning suddenly realized, no wonder the Dan Fang on the earth is so precious, it can really be said that it is a thousand miles away.

"Then do as the Taoist chief wants. Jiang Ning nodded and said.

"Little brother, this Dan recipe is extremely special, and the old decay is not completely sure, if the refining fails......"

Before Li Tian finished speaking, Jiang Ning interrupted him and said, "Dao Chief, please rest assured, I am not a person who does not know right and wrong, it is my honor that Dao Leader is willing to help, even if it fails, it is the will of heaven, how can I blame Dao Chief." ”

Li Tianyi looked at Jiang Ning, nodded with satisfaction, and then turned his head to look at Lu Daochang.

"Senior brother, bring the grinding tools, I will refine this elixir with my own hands. ”

There was only one piece of the last piece of material left in the spirit pill, and Jiang Ning had no bottom in his heart, but now there was no other way but to try it hard, and then Lu Daochang took the grinding groove, which is a manual tool, throw the material into the grinding groove, and slowly grind the material to powder.

Li Tian's expression was very concentrated, and then he directly picked up the purple spirit vine without saying a word, and as the purple spirit vine was thrown into the grinding groove, Jiang Ning's heart skipped a beat.

"Wait ......," Jiang Ning hurriedly interrupted.

"Little brother, what's wrong?" Li Tianyi turned his head and looked at Jiang Ning suspiciously.

"Daochang Li, I have an idea, since this material is to take its essence, can it be possible to directly extract the essence spirit liquid in the material, so that it will not only reduce one step, but also preserve the essence in the material to the greatest extent. ”

Jiang Ning tentatively said the extraction method used in the alchemy of the Heavenly Dome Continent, because Jiang Ning carefully weighed it and thought that the extraction method of the alchemy of the Heavenly Dome Continent was more reasonable.

"Little brother, do you know about the extraction of spiritual liquid?" Li Tianyi's eyes widened, his hands grabbed Jiang Ning's arm, and he asked with an incredulous expression.

Jiang Ning just said tentatively, but he didn't expect Li Tianyi's reaction to be so big.

"Uh...... Is there any problem?" Jiang Ning was a little panicked and asked after a pause.

"This spiritual liquid extraction is an ancient secret method, according to legend, thousands of years ago, the ancestors used the method of spiritual liquid extraction to extract the essence of the material, but this method has been lost until now, and the old decay is only mentioned in ancient books. ”

After Li Tianyi explained, his expression dimmed with excitement, he looked at Jiang Ning after all, he was only a young man in his 20s, and he didn't expect Jiang Ning to know the method of spiritual liquid extraction, but since he had already said this, Li Tianyi still asked symbolically.

"Little brother, how did you know the method of extracting the spiritual liquid, and can you master this secret method?"
