Chenshi.

Seeing that the ground had turned into a water spirit stone that had no blue fluorescence and was not without a difference from ordinary stone beads, Shi An couldn't help but be a little stunned.

Today is the third day of coming to Zhen Yifang, the night of the end of the auction, Shi An quickly ran into Zhen Yifang, Zhen Qing was waiting in the back hall, when Shi An handed over the beast pill, his eyes lit up, and he only ordered someone to arrange for Shi An to stay, and then rushed into the study to study it carefully. "This Zhen Qing senior is really obsessed with alchemy, and he doesn't have a superfluous word. That's what Shi An thought at the time.

In the next three days, except for a short sleep time and asking someone to inquire about the big events in the city after the auction, Shi An was all about cultivating. With the support of the Water Spirit Stone, the spiritual mist in his qi sea became thicker and thicker, and the qi sea also expanded day by day.

He hadn't slept all night last night, and when he was ugly, Shi An's sea of qi had swelled to the size of a cherry. When the entry of the aura could no longer make the sea of qi expand, there was a sudden muffled sound in the body, and after that, there was no longer any feeling of suffocation in the sea of qi, but it was suddenly enlightened, he understood that the first layer of qi refining had been completed, and he had entered the second layer of qi refining, and it was difficult to inhale the aura again with another layer of Zhou Tian meridians at this moment.

So he took out the "Four Elephants Heart Method" from his bosom, referred to the content of the second layer of the Guihai Method, and began to try to open up the second Zhoutian meridian.

The seventeen acupuncture points of this meridian Shi An are also more familiar, similar to the Du Mai, except that the Du Mai starts from the Changqiang acupoint in the middle of the waist and back, goes up along the spine, passes through the back of the neck to the Fengfu acupoint, goes up along the midline of the head to the Baihui acupoint on the top of the head, and then goes down through the forehead to the gingival intersection acupoint in the middle of the upper teeth, a total of 28 acupoints. The second layer of the Zhoutian meridians of the method of Guihai starts from the Baihui acupoints on the top of the head, and descends to the fifteen acupuncture points of the meridian meridians, namely the back top, the brain household, the wind house, the dumb gate, the large vertebrae, the Tao Dao, the body pillar, the divine way, the spiritual platform, the yang, the tendon contraction, the center, the spine, the suspension pivot, and the life gate, and finally reaches the sea of qi. With the experience of the last time, it didn't take much effort to get through these seventeen acupuncture points this time, although it still took a little longer to open up the meridians from the life gate to the sea of qi, but it didn't take two hours to open up the entire meridians.

Compared to the first layer, this Zhou Tian meridian not only shortened its running time, but also increased the amount of spiritual energy transported. This was a good thing, but for Shi An, it was exactly the same as the initial situation of the first layer, as soon as the aura formed a spiritual mist, it turned away.

"Alas, the sea of qi has begun to absorb aura again. Shi An was a little helpless. And soon after, the aura in the water spirit stone was exhausted and turned into ordinary stone beads.

I can't cultivate for the time being, so let's go meet Zhen Qing's seniors.

Shi An changed into another gray-brown oil-stained clothes, washed the dirt on his body, and came out of a small house in the backyard. This is the place arranged for the Danfang guys and apprentices in Zhen Yifang, and now only Shi An lives alone, and everyone else is crammed into a more spacious room.

When approaching the study, Shi An saw Zhang San, the guy who originally received Yuan Miaozi and the others, and hurriedly stepped forward to greet him: "Third brother, is there any news outside now?"

Zhang San shook his head: "It's still the same as what I learned yesterday, there is no progress in Liu Gongzi's death, but people outside say that Liu De went to rob the beast pill that your husband bought, but he didn't expect to be killed." Originally, the death of a monk in the early stage of foundation building was not a big deal, but Liu De was the son of an elder, which caused an uproar. ”

Shi An thanked Zhang San for arching his hand, "Third brother, thank you for not telling anyone else my identity." ”

Zhang Sanyi waved his hand, "It's nothing, the old man has long ordered not to say a word to the outside world, and we just do it." In fact, as long as we can make the old man happy and ask him to give him more pills, we will be grateful. Eh, speaking of which, the old man likes you a lot, and if he has the opportunity, he will say a few more kind words for us. ”

"You don't know, I am a difficult patient of Zhen's predecessor, and he naturally treats me differently. Shi An smiled bitterly, "I'll go in and meet Senior Zhen." ”

Zhen Qing was sitting at the desk pondering things at this time, and when he saw Shi An coming in, he first swept it with his divine sense, and then said with a smile: "Oh, I've risen to the second floor, what's wrong with cultivating now?"

Shi An knew the meaning of his words, so he said, "It's still the same as the first layer, the aura has been absorbed. ”

"You're here to ask about the progress of refining this Spirit Blocking Pill?"

Shi An nodded yes.

"Don't worry, I'm about to tell you about this elixir. This medicine comes from an ancient prescription, but the specific use is not written, it is estimated that in ancient times this medicine was very famous, and the use was well known. You look at these elixirs, Sentengen can slow down the flow of aura and prevent the output of aura in the sea of qi, bitter orchid is to inhibit the operation of the sea of qi, Hu Ye is to strengthen the outer wall of the sea of qi, Yang Li fruit is to repair the damage of the sea of qi, and Wusi bamboo is to nourish the sea of qi. It can be seen from the medicinal properties that this pill is not a tonic and gain pill, but a therapeutic pill. Based on the dosage of several elixirs, it can be roughly estimated that it should stabilize the sea of qi and prevent the leakage of spiritual energy, so I think this elixir solves the problem of additional absorption of spiritual energy by the sea of qi. Now there is only one question, and that is the purpose of that beast pill. The beast pill is generally used to improve cultivation after the pill period, why should it be used here, I have been pondering it for the past few days. ”

After hearing this, Shi An couldn't help but feel a little annoyed in his heart, Zhen Qing was obviously not sure of the exact efficacy of this elixir, and it was just his guess that he could solve his own problems, so he took it out to treat himself, and let us work hard to obtain the beast pill, but in the end, I don't know why we used him.

Zhen Qing also seemed to see Shi An's resentment, and comforted: "Although the exact use of this elixir is unknown, it is always beneficial to the sea of qi, and coupled with the Water Beast Pill, it will definitely be of great benefit to your cultivation." I haven't been doing it for a long time in the past few days, just thinking about how to refine this elixir. ”

Shi An was even more annoyed when he heard this, and muttered: "I haven't even figured out how to refine the pill, what kind of alchemist is this?"

Zhen Qing was not annoyed when he heard it, and said, "This is because you don't understand the truth of alchemy. The water aura is not abundant in my place, and I don't have any water spirit stones for you, even if you cultivate, the aura will be absorbed by the sea of qi. So I advise you not to cultivate these days, give you a few books, you can see how to make pills and the related content of commonly used various spirit grasses, and the long knowledge will also be good for your cultivation in the future, do you think this is good?"

Shi An thought about it, it was useless to complain about Zhen Qing now, the efficiency of cultivation was low, it was really better to wait for him to alchemy, read the relevant books, and at the same time wait for the master to come to pick him up, so he said: "Then thank you Senior Zhen." ”

"Okay, I'll give you two books to read," he said, got up and went to the bookshelf to pick out two and handed them to Shi An, "One is "General Theory of Lingcao", which talks about common Lingcao elixirs, and the other is "Introduction to Dan Dao", which tells about the basic methods of refining elixirs, and later introduces some unilateral prescriptions of ordinary elixirs. You have to read carefully, the content of the two books overlaps, which can confirm each other, if you don't understand any questions, you can always ask me. You don't have to return this book after reading it, I'll give it to you. Now I have to continue to think about the details of refining this pill, so I won't accompany you much. ”

Shi An saw that Zhen Qing had given an eviction order, and it was not good to stay long, so after expressing his gratitude, he took the book back to the room.

In the next few days, in addition to inquiring about the news of Shizu every day, Shi An spent the rest of his time in the hut reading these two books. There is still no news from Shizu, Shi Anxin thought, there is still a period of time before the appointed day, although Shizu has no magic weapon, but he is also a master of summoning the country, there is no need to worry.

"General Theory of Lingcao" is very easy to understand, after all, Shi An is also a medical background, although the herbal medicine in the immortal world and the secular world are very different, but the pharmacology is the same, only three days to understand most of the elixir names, forms, medicinal properties, etc., just wait for the opportunity to practice in the future. As for the efficacy of the spirit resistance pill, Shi An pondered for a long time and didn't come up with a way, and he could only think that what Zhen Qing said was good.

And that "Introduction to Dan Dao" is much more difficult to chew, mainly because the medicine methods of the immortal cultivation world and the secular world are different. Although they are all about combining a number of herbs in a certain proportion, but the medicines in the secular world are soups, powders, pills, ointments and the like, and the production is relatively simple, and the medicines in the world of cultivating immortals are mainly Dan, unlike the secular world, which grinds all kinds of herbs into powder after drying or simmering, and then mixes the powder with honey, water, wine, etc. to make pills, but melts, mixes, and solidifies in the Dan furnace with the fire of heaven, earth, or people, and the melting points of various herbs are different, the properties are different, and the way of combining them is also different.

Alchemy requires a strong ability to control fire, control aura and strong divine sense. The ability to control the fire is reflected in the melting stage, through the control of the heat, in the Dan furnace to divide different temperature areas in order to melt different elixirs. The more types of elixirs used, the more areas in the Dan furnace will be divided, and without excellent fire control ability, there is no way to achieve the purpose of coexistence of multiple temperatures at the same time.

The combination of the melted elixir is also very particular. The attributes of the five elements of different elixirs are different, and the combination of elixirs with the same attributes, the combination of elixirs with attributes, and the combination of elixirs with similar attributes are very different, which means that it is not enough to know the properties of the medicine, but also to have a strong ability to control the spiritual power, and use spiritual power to control the combination between the melted elixirs.

Divine consciousness control is mainly in the stage of becoming a pill, and the internal instability of the combined elixir is extremely unstable, and the phenomenon of collapse may occur at any time, so it is necessary to use divine consciousness to pay attention to the balance of power within the elixir at all times. The minimum starting point for all this is the foundation building period, because only at this stage can the divine consciousness begin to cultivate, it is possible to reach the level of meticulousness, and only at this stage can the spiritual power be released, and it is possible to control the balance of various forces within the pill at any time.

Shi An felt that his head was big after watching it for three or four days, the general rules of fire control, the melting point of various elixirs, the combination of elixirs, the spiritual power and divine consciousness, etc., the concepts were complicated, and the operations were even more complicated. Fortunately, the principle has been understood, and several common pills attached to the back have also been memorized, and if you want to practice, you have to wait for the opportunity to reach the foundation building period.

As for the divine sense, according to Yuan Miao Master, his divine sense is very strong, and while the two books have been read and there is nothing to do, it is better to ask Zhen Qing for basic related classics.
