After a long time, Su Jing finally finished reading all the jade slips, most of which were Dan recipes, and the few were some exercises.

And the content in one of the jade slips set off a slight wave in Su Jing's heart, which had just calmed down.

The content of that jade slip is an alchemy experience, according to the memory obtained from soul searching, Su Jing then remembered that this alchemy experience jade slip was still obtained by a yellow-faced man at an auction house.

It is said that this jade slip was written by an alchemy master in Yanzhou, what is it called Master Feng, the yellow-faced man's memory is not very clear, but this jade slip was obtained at a great cost, and it is also quite precious.

At this time, after Su Jing looked at this jade slip, he had a slight urge to try alchemy in his heart, after all, this experience said that the alchemist had a prerequisite, that is, the divine sense must far surpass the cultivators of the same level.

If Su Jing had remained conscious, he would definitely sigh at this moment.

Well, goldfinger, cool, you're everywhere!

And Su Jing just met this condition because of the black beads, and the remaining medicinal materials were a little in the yellow-faced man's storage bag, which was enough for Su Jing to try.

Furthermore, even if Su Jing failed to refine and turned into a waste pill, Su Jing could use black beads to refine it into a perfect pill. It's just that this experience jade slip says that there are generally three possibilities for alchemy failure.

The first is that the heat is not controlled enough when the medicinal materials are refined, resulting in the medicinal materials not meeting the requirements, and they cannot become pills, in this case, Su Jing cannot be refined into perfect pills.

The second is that the control of the divine consciousness when becoming a pill is not fine enough, which also leads to the inability to become a pill, and Su Jing naturally cannot be refined into a perfect pill.

The last one is that the heat is not well controlled when it becomes a pill, resulting in too many impurities and being inedible.

Generally speaking, if the impurities are more than 40%, they are inedible, and for every 10% of the impurities in the elixir, the grade will be increased by one grade. For example, a low-grade low-grade pill, the impurities are about forty percent, and when the impurities are thirty percent, the pill will become a low-level medium-grade pill.

And after refining the elixir countless times by the alchemists, it was found that in any case, except for special circumstances, the impurities of the elixir could not be less than two percent, that is, there were no special circumstances that could only reach the top grade.

Of course, there are some people who are very lucky, and by chance, there may be less than two percent or perfect pills, but this situation is extremely rare.

But the situation that these impurities lead to the pill becoming a waste pill and cannot be taken is not a problem for Su Jing, so he has a unique advantage for alchemy.

At this moment, Su Jing pondered for a moment, and then decided to learn this new skill, but before alchemy, a series of preparations were needed.

The problems of medicinal herbs, medicine tripods, and pills have long been solved from the yellow-faced man's storage bag, and the remaining fire required for alchemy is a problem.

The fire of alchemy is most suitable for the Dan fire of a monk in the Jindan period, but this is obviously not satisfied with Su Jing. The second is the earth fire, the earth fire generally exists in the depths of the ground, and in many sects, there will be a special place for this kind of earth fire, so this is somewhat possible for Su Jing.

And the worst one is to use your own spells as the fire required for alchemy, such as fireball techniques and the like, but this method has the lowest success rate. After all, the above two methods have their own advantages, Danhuo has the aura of Dan, which can greatly increase the rate of Dan, and the earth fire is stable and easy to control, so it also has the effect of increasing the rate of Dan.

Spells, on the other hand, have no advantages, so Su Jing will not use spells unless it is absolutely necessary.

At this moment, after thinking clearly, Su Jing got up and walked out of the cave, he planned to go to the Personnel Pavilion again to ask the pock-faced senior brother if there was any earth fire in the Tiangang Sect.

After a short time, Su Jing had already arrived at the Personnel Pavilion, but fortunately, the Personnel Pavilion was still the original pock-faced senior brother, after all, people who were already familiar with him would be easier to talk.

In the end, after some surprise from Senior Brother Ma Face, and the excuse that Su Jing had thought of in advance, he still fooled Senior Brother Ma Face.

After all, Su Jing's five spirit roots were known to the pock-faced youth, and in just a few months, Su Jing had reached the third level of qi refining, which was really a bit incredible, but fortunately, in the end, Su Jing simply fooled this matter by taking more pills, after all, everyone has some secrets, and the pock-faced young man also understood this truth, so he didn't delve into it.

Then Senior Brother Ma Yan was surprised why Su Jing asked about the place of the earth fire, but fortunately, Su Jing had already thought of an excuse in advance, and on the grounds of rising knowledge, he fooled Senior Brother Ma Face again.

In the end, sure enough, there was earth fire in the Tiangang Sect, and after the description of Senior Brother Ma Face, the place where the earth fire was located was under the Dan Hall.

Speaking of Dantang, this Dantang has been in Tiangang Sect since the beginning of the sect, although Tiangang Sect was famous for swordsmanship before, and most of the disciples in the Tiangang Sect before were sword cultivators, and it was even a Tiangang Sword Saint who shocked the southern continent of Guangdong!

Although later, after the mysterious disappearance of the Tiangang Sword Saint, the Tiangang Sect was squeezed out by other major sects, and there was no successor, which caused the Tiangang Sect to decline, and now, it has shrunk in a small martial country, and even the capital of the martial country, Yanzhou, can not stay, and can only fight with several small sects in this middle county.

But this Dan Hall has been preserved to this day, and the founder of this hall was the sect master of Tiangang Sect at that time, considering the inconvenience of distributing offerings in the sect, so he set up this hall.

Unexpectedly, this Dantang later achieved very good results, so it has been followed and has not been abolished until now. And now, the hall master of the Dan Hall, Zhu Chentao and Zhu Tang Master, is already a middle-level low-grade alchemist, and his own cultivation is also in the middle of the foundation building period, so he is also an admirable existence in the Tiangang Sect.

But this time, Su Jing borrowed the fire but had nothing to do with Hall Master Zhu, after all, Su Jing was a small role in the third layer of qi refining, and in the eyes of Hall Master Zhu, he was just a scumbag.

And this Dantang is at the foot of the East Peak Mountain, this East Peak is the largest of the five peaks of the Tiangang Sect, and the radius is all the East Peak.

After walking for half an hour, Su Jing finally arrived at the foot of Dongfeng Mountain, and as soon as he arrived at this place, a huge building came into Su Jing's eyes.

A huge attic, about dozens of zhang high, occupies a few miles of space, where is a huge plaque with gold inlaid in the attic, on which are written "Dantang" two big characters.

And the entire attic seems to be composed of sandalwood, and even a path about two zhang long in front of the attic seems to be made of a special kind of jade, and the whole building is full of luxury, which makes Su Jing stunned.

But if you think about it carefully, it's right, although the alchemist is relatively poor in the early stage, if he can successfully advance to the later stage, the spirit stone will naturally come like a roll, so it is not an exaggeration that this Dantang is so luxurious.

At this moment, Su Jing stopped observing and walked towards the Dantang.

As soon as he entered, the setting inside the Dantang made Su Jing's heart shake, the internal floor tiles were basically all jade pads, and among these jades, Su Jing felt that nearly a hundred of them had strong aura fluctuations.

"Spirit stones!" Su Jing's heart shook again, there were actually a hundred and ten spirit stones in this floor tile! And it seemed to be placed in some special pattern.

Su Jing quietly emitted his divine sense and began to observe.

"It's ...... Formation?"

Under the observation of Su Jing's divine sense, Su Jing saw that within the scope of this spiritual stone, the spiritual energy was several times richer than that of other places, and what could achieve this effect was only the formation that Su Jing had learned in the library pavilion.

This formation is divided into two kinds, one is the landing formation formed by the temporary placement of various materials, this formation is often in the form of a mountain protection array or a gathering spirit array, and there are some protective and gathering aura effects.

The other is to make a special method into a formation plate or something like that, which is usually used by monks to quickly form a formation, which is simple and fast, but the power is not as great as the landing formation, but it does not need to be tediously arranged, nor does it need to learn this knowledge, so it is also quite popular with monks.

Now this formation in the Dantang is a simple landing formation, and according to Su Jing's current observation, it should be a formation with a spirit gathering effect.

Su Jing, who had thought clearly at this moment, withdrew his divine sense and set his gaze on other places. There was nothing surprising in this Dan Hall except for this simple Spirit Gathering Array, and only four doors existed here.

Three of these four doors have words written on them, which are "Dan", "Qi", and "Medicine", and the remaining one is blank.

And these three separate words, Su Jing guessed that it should be alchemy, refining tools and places for planting elixir.

At this moment, after observing the four doors clearly, Su Jing's eyes fell on a sloppy old man lying on the Taishi chair in front of the four doors with his eyes closed.

This sloppy old man's white hair was unkempt, a layer of oil on his face made his face slightly shiny, and the white clothes on his body were tattered, and he could vaguely see that it was the costume of Tiangang Sect. The only thing that could be seen was a green ring on his left index finger, which had an emerald green sheen, a bit like an emerald ring.

Although the appearance of this sloppy old man is very unsophisticated, Su Jing swept it with the Heavenly Eye Technique, and immediately startled Su Jing, this sloppy old man with Su Jing's Qi Refining Great Perfection Divine Sense, it turned out to be a blur, and the divine sense was as terrifying as entering the abyss!

In this case, it is obvious that this sloppy old man is a senior in the foundation building period, so Su Jing does not dare to slack off, if he makes a senior in the foundation building period unhappy, in the future, in this Tiangang Sect, Su Jing may not be able to move an inch.

Su Jing walked over and made a note to the sloppy old man, and said respectfully: "Senior, may I ask if the earth fire required for this alchemy is inside this gate?"

The sloppy old man slowly opened his eyes as if he had just woken up, but his eyes were not cloudy as the old man, but clear, which made Su Jing secretly frightened again, and at the same time glad that he was prescient.

The sloppy old man glanced at Su Jing obliquely, then closed his eyes again, and the old voice slowly came out of his mouth: "One low-level spirit stone every day of use." ”

Su Jing didn't dare to complain about the high cost of using the earth fire, so he respectfully took out ten low-level spirit stones from the storage bag, handed them over, and said, "The junior will use it for ten days first." ”

The sloppy old man let out a "grace", and then his eyes didn't open, and with a wave of his hand, the spirit stone in Su Jing's hand suddenly disappeared, making Su Jing feel shocked again.

Su Jing suppressed the surprise in his heart, made another compilation, and then walked into the door with the word "alchemy" written on it.
