Long Xiaoyao saw that there were no other customers in the Dan shop, so he said to the owner of the Dan shop straight to the point: "Fellow Daoist, I accidentally got a Dan prescription and plan to learn alchemy, I wonder if you can teach alchemy?"

The middle-aged monk looked at Long Xiaoyao, and when he heard him say that he could get the Dan Fang, there was a trace of greed and eagerness in his eyes, and said, "I don't know what Dan Fang you got?"

Long Xiaoyao said: "There is a Qi Raising Pill of level 7-9 in the Qi cultivation period, and a Fire Yuan Pill of the initial level of foundation building. ”

When the middle-aged monk heard this, his eyes glowed brightly, and after a long silence, he said: "Daoist friends should know that alchemy is a secret that is not passed on, so let's make a price for Daoist friends, how about I buy those two Dan prescriptions, or exchange them for pills?"

Long Xiaoyao knew that the other party had already been tempted by the Dan Fang, and said: "Don't worry, Daoist friends, I know that alchemy is very precious, and I will never let Daoyou teach it plainly, there are some spiritual grasses under it, as long as Daoyou can teach alchemy under it, I will use the elixir as a reward." ”

As he spoke, Long Xiaoyao took out a jade box containing several elixir garden spirit grasses and handed it to the shopkeeper, who opened the jade box and saw that his face immediately changed greatly. Of course he knew the spirit grass in the elixir garden, but he didn't have a chance to see it in an alchemy shop, let alone get it, and when he saw the spirit grass in his hand, he was overjoyed in his heart, and he thought that the other party was going to learn alchemy, and his face changed for a while.

He was a disciple of a small alchemy family, the family was very small, and the highest cultivator was only the middle level of Jindan. Although alchemy is the most profitable, because their family lacks the best pill prescriptions, they can only refine some of the most ordinary pills, so the family is only a dismal business, and naturally they will not provide him with good immortal cultivation resources.

But no matter how small the alchemy family is, no matter how ordinary the alchemy is, it is also determined by the family to be a secret that will not be passed on, if he teaches it to outsiders in private, he will inevitably be punished by the family, which makes him look at the huge wealth in front of him but dare not agree without permission.

Long Xiaoyao looked at the shopkeeper's uncertain face, and immediately knew that the shopkeeper had been impressed, but he couldn't make up his mind, so he decided to add another fire. So, pretending to be ruthless, he gritted his teeth and took out two jade boxes containing spirit grass, handed them to the other party and said, "As long as Daoist friends are willing to teach me alchemy, I will give these spirit grasses to Daoist friends." ”

The wealth is moving, the shopkeeper hurriedly opened the jade box, and when he saw the spiritual grass in the jade box, he could no longer restrain his greed, and naturally he would no longer care about any family rules, but he must maximize his interests.

So, the shopkeeper rolled his eyes and said: "If Daoist friends sincerely plan to learn alchemy, I am not absolutely unable to teach it, but I can't divulge the family's Danfang, you must not mention to outsiders that I am the professor, and, in addition to these spirit grasses, the Danfang you get must also be copied by me." ”

Long Xiaoyao was originally going to let the shopkeeper copy the Danfang, and also prepared twenty spirit grasses, but he didn't expect the shopkeeper to take out thirteen spirit grasses, so he couldn't wait to agree, it seems that the other party really hasn't seen anything.

Long Xiaoyao said with satisfaction: "Don't worry, Daoyou, of course I won't mention it to outsiders, I just want to take the alchemy pill by myself, and it's not for sale, of course the Danfang won't keep it secret from Daoyou, as long as Daoyou teaches me alchemy, I will let Daoyou make a copy." ”

When the shopkeeper heard this, he didn't hesitate, and made a trick, and actually closed the door of the Dan shop directly, and then took Long Xiaoyao into the room behind the store.

Sure enough, as Long Xiaoyao expected, that room was the alchemy room. The room is only less than ten square meters, and there are no furnishings in the room, but there are two magic circles that prohibit it, which can isolate the detection of divine consciousness from the outside world, and can also isolate the high temperature and spiritual energy leakage in the house.

The shopkeeper immediately took out a cyan pill, a few herbs, and a few jade boxes. He hoped to teach Long Xiaoyao earlier, not only could he get the spirit grass and pill as soon as possible, but he could also let Long Xiaoyao leave as soon as possible, so that he would not reveal the secret of his private alchemy.

As an alchemist, of course, the shopkeeper also cultivates the fire surname exercises, he has a second-level fire spirit root, and a yellow flame more than an inch high appears in the palm of his left hand, which is the true fire of an immortal cultivator. The true flame was like the flame of a candle, condensing in one place in his palm, instead of covering the entire palm like when refining the materials of the demon beast.

The shopkeeper put his left palm under the Danding and warmed the Danding. After a while, the Danding was already filled with a scorching aura, and he immediately put in a medicinal herb, that herb was only the most ordinary green leaf grass, after entering the Danding, it was immediately melted into a pool of green and green by the high temperature in the Danding, mixed with some dark green juice.

The shopkeeper said: "The first step in alchemy is the refining of medicinal herbs, and there are not many active ingredients in low-grade medicinal herbs, which must be heated to make them liquid before they can be extracted. First of all, to understand the melting point and refractory surname of the herb, the temperature of the Danding must be able to melt the herb quickly, the temperature is too low, the melting is slow, the herb will be heated for a long time, the active ingredients of the herb will be lost, and the temperature is too high, the herb will be directly incinerated. ”

"When the herb is melted into a liquid state, the active ingredient must be extracted with the divine sense. The active ingredient of this green leaf grass is the cyan particles in it, and other impurities should be avoided when extracted, and the extraction speed should be fast, and the liquid medicine will be incinerated after a long time. ”

Long Xiaoyao has been observing the shopkeeper's every move and the subtle changes in the Danding with his divine sense. I saw that twenty cyan particles flew out of the liquid medicine in the Danding. After the cyan particles gathered together, they floated above the Danding, and then, more than a dozen cyan particles flew out of the medicinal liquid.

Although the cyan particles are invisible, as they continue to gather, the collection of particles floating above the Danding gradually increases, and it is the size of a sesame seed for a moment, and soon it becomes a cyan droplet the size of a mung bean.

There are fewer and fewer cyan particles in the medicinal liquid in the Danding, and the frequency of the particles flying out gradually slows down, and it doesn't take long for the medicinal liquid in the Danding to be burned to ashes, and the remaining cyan particles are of course all wasted.

Long Xiaoyao watched quietly, and he noticed that the shopkeeper had brought some other particles with him in the process of extracting the cyan particles. Indeed, the particles are almost inseparable from each other, and if you are not careful, other impurities will be entrained, no wonder the alchemy experience of ancient cultivation requires the cultivation of fine control skills of the divine sense, if you cannot ensure the purity of the herb extraction, the quality of the pill will be greatly reduced.

The several kinds of herbs that the shopkeeper had refined successively were all the same process, except that the temperature of Danding was different from the strength of the true fire he cast. Next, it is the formal refining of the elixir.
