Fang Ling knew that the sunspot must be from this Storm Cloud Village, so he was curious: "Does Brother Niu know where the people from Storm Cloud Village caught that barbarian girl?"

Niu San smiled lewdly: "Little brother, you are asking the right person, there are really few people who know about this, but for the sake of you buying my things, I will tell you that the place is in the Tiger Leaping Cliff." ”

"Tiger Leaping Cliff? I heard there's a waterfall there. Fang Ling asked.

Niu San smiled and said: "The scenery of that place is really good, but in the past, we had to climb more than a dozen mountains, and even those of us who are familiar with mountain roads will take two days." But soon after the Tiger Leaping Cliff, there is a large mountain road, which is a shortcut to the surrounding counties and townships, and one of them leads to our Moshui Village. ”

"Moshui Village, it turns out that Brother Niu is a subordinate of the master of Qiu Zhai, no wonder he is so heroic and extraordinary. Fang Ling couldn't help but give a thumbs up.

Niu San couldn't help but 'touch' his face, and said confidently, "Little brother has won the award, in fact, I'm handsome, handsome, and heroic, it's just a little bit worse." ”

Fang Ling smiled and asked, "Brother Niu, can you take me a ride when you go back to Moshui Village, I also want to go to the county and township next to me from the Tiger Leaping Cliff." ”

Niu San patted his chest very happily and said, "No problem, we will leave the night after tomorrow, and the little brother will come over directly at that time." ”

Things went so smoothly that Fang Ling breathed a sigh of relief, left the black market, and returned to Feng County It was already early the next morning.

Back in the house, Fang Ling put down a bag of things, picked up the atlas and glanced at it, and threw it aside, this thing he saw the eunuch turn over when he was young, there was nothing new about it.

The few books left in the baggage are all books on self-cultivation and cultivation, and I don't know which Taoist temple they stole from.

However, as soon as he put down the last book, he picked it up again, because it felt a little strange when his hand "touched" the cover.

This cover is made of ordinary sheepskin, soft, and there is nothing strange about it, but when you press it lightly with your fingers, you feel that there seems to be a layer of something in the cover.

Fang Ling was curious, and immediately took it out, cut the book cover, shook the book upside down, and actually shook out a square stack of paper.

Spread out the paper, and when he saw the words written on it clearly, Rao is Fang Ling almost screamed excitedly, this turned out to be a Dan Fang!

Moreover, this is not an ordinary Dan prescription, but a second-level Dan prescription.

The art of alchemy has an ancient history on the earth, and it seems that it has appeared when civilization appeared, and it is said that at that time, there was already a theory of immortal ascension.

There are also cultivators in the mortal realm who refine the pill, and the alchemy is the pursuit of immortality, but the effect that ordinary pills can achieve is only to strengthen the body. And in the martial arts, most of them don't know anything about alchemy, and even fewer people improve their skills by taking pills, and I'm afraid that only martial arts families with Xianmen disciples at home know about it, and these are naturally secrets that are not passed on.

Compared with the alchemy of the mortal world, the immortal gate seems to be perfect and formal, of course, this is also what Fang Ling learned from Xiao Xue's mouth, in order to get the news of the elixir, he fought for a lot of time at that time.

Compared with the Seven Realms of Martial Arts, the Dan Fang is also divided into 7 levels, the 1st level Dan Fang is the roughest, and the refining time is relatively short, Pei Yuan Dan is one of them, suitable for cultivators in the Brute Force Realm and the Qi Storage Realm, used to strengthen the body, store qi and nourish the body.

Although it is the most superficial pill, it can shorten the time of the martial arts realm, as far as the brute force realm is concerned, it takes seven to eight years for the average martial artist to reach it, but if you take Pei Yuan Dan every day, it can shorten the time to one or two years. Therefore, even if it is the most superficial Danfang, if it is known by people in the martial arts, it will also cause a bloody storm.

And this kind of pill called "Hun Tie Dan" is a level 2 pill, which can be taken by cultivators of the Qi Storage Realm and the Rigid Power Realm, and there are many names of "medicine" materials written on it, as many as two hundred, among which there are many rare "medicine" materials, and the refining process is similar to Pei Yuan Dan, but it takes a whole day to spend hours.

After the battle with Chu Li, Fang Ling had been pondering how to break through the Rigid Force Realm, and now he was overjoyed when he accidentally discovered this Hun Tie Dan.

He immediately went out and personally went to the "medicine" pharmacy in the city to select "medicine" materials, and if there were more than a dozen flavors that could not be bought here, he sent people to buy them in the surrounding counties.

It wasn't until the evening that all the "medicine" materials were gathered, and Fang Ling came to the kitchen, put the "medicine" ding on the stove, and prepared to raise the fire and alchemy.

He was already familiar with the cleaning of "medicine" materials, although the names of these "medicine" materials were different, but the processing methods and classifications were roughly the same as Pei Yuandan.

After sorting out the "medicine" materials, Fang Ling began to refine the pill, and after raising the firewood, looking at the rolling firewood, he suddenly remembered something.

I remember that Xiao Xue once said that there is a difference between inner fire and outer fire in this alchemy, when the cultivation reaches the realm of qi, it can urge the inner fire alchemy, and this internal fire is the qi of heaven and earth that is inhaled into the body.

However, if he cultivated the technique of melting the sun and the moon, and now he can also put the sun fire energy and the moon yin ice energy on the sword in battle, wouldn't that also be equivalent to using the inner fire to refine the pill?

Fang Ling's heart moved, and he immediately prepared to implement this sudden idea, if any Immortal Sect disciple knew that he thought like this, he would definitely laugh out loud, thinking that his idea was arrogant.

You must know that the seven realms of martial arts are divided into brute force realm, qi storage realm, rigid force realm, melting qi realm, xing qi realm, transforming yuan realm and heavenly fusion realm.

As Fang Ling knew, cultivating the art of cultivating the truth would make the cultivator master the energy of the Qi of Heaven and Earth prematurely, which was also one of the reasons why the disciples of the Immortal Sect were able to reach a very high level at a young age, but to truly reach the realm of the release of the Qi of Heaven and Earth, they had to reach the Qi Melting Realm, and to master it proficiently, they had to be in the Qi Realm.

Therefore, for the disciples of the Immortal Sect, this alchemy technique, the internal fire must be in the realm of qi, even if there are people with outstanding talents, it is also in the realm of melting qi, and this realm of qi storage may simply release the inner fire alchemy.

However, the Sun Melting Moon Solution is very different from other cultivation methods, not only can it be used in combat, but it can also be used to treat illnesses.

Therefore, this also made Fang Ling reach the level of releasing the qi of heaven and earth in the Qi Storage Realm, which was enough to advance the Inner Fire Alchemy Pill by two or three realms.

Fang Ling began to try to concentrate the sun's fire energy between his palms, slowly releasing it, and the fire energy floated on the palms, forming an internal fire force.

Fang Ling secretly rejoiced, he didn't expect that this internal fire could really release heat, and if it was combined with the firewood below, it would definitely be able to greatly advance the time for alchemy.

However, he was suddenly stunned again, and realized that this idea was wrong, that is, fire.

Xiao Xue said that in the art of alchemy, heat is an extremely important part, and if the temperature is too high or too low, it will lead to the failure of alchemy, so it is necessary to open the lid to dissipate heat and stir when the temperature is too high, and increase the heat when the temperature is too low, and use a pair of hands to perceive the change in temperature, so as to control it.

However, once an internal fire is added, it becomes difficult to grasp the temperature, and it can even be said that it is impossible to accurately control the temperature at all. If you use only one hand to release the internal fire, the temperature will also become unbalanced.

However, Fang Ling felt a little strange, it stands to reason that the addition of this internal fire can greatly increase the speed and effectiveness of alchemy, then, this internal fire is probably not so simple to join.

Fang Ling's eyebrows were deeply locked, he had been wise since he was a child, and no problem could be stumped, although this alchemy technique was just getting started, but the words he heard from Xiao Xue and the alchemy in the past few months had given him a lot of understanding.

So, without any guidance, Fang Ling studied and "groped" at the same time, and gradually "touched" the clue.

The so-called internal fire refining is not simply to release the qi of heaven and earth to increase the temperature, but to cross the qi of heaven and earth into the ding, so that it forms another space in the ding, which is the real mystery of the internal fire. Therefore, the fire of the inner fire is not the real temperature, but the transmission of energy.

Fang Ling had no master, and after comprehending this, he suddenly had an epiphany, if Xiao Xue was here at this time, I am afraid that he would regret passing on this alchemy to him, just such a comprehension made Fang Ling surpass the alchemy of the disciples of the Qi Storage Realm Immortal Sect to a certain extent, and it can even be said that it has reached an unmatchable level.

As a result, the internal fire rushes into the tripod along the wall of the "medicine" tripod, forming a layer of space in the tripod, and through the continuous heating of the external fire, the "medicine" materials absorb the qi of heaven and earth.

And in the place where Fang Ling couldn't see, inside the "Medicine" Ding, with the influx of the Qi of Heaven and Earth, the strange lines on the Ding Wall also flashed with circles of light, sometimes bright and sometimes dark.

Time passed minute by minute, Fang Ling concentrated on refining the pill 'medicine', without a little distraction, the qi of heaven and earth in his body gushed out along his breath, and at the same time, the technique of melting the sun and the moon was running in the body, constantly releasing the absorbed qi of heaven and earth, and this alchemy was like a practice.

By the next morning, after about 6 hours, Fang Ling had finally refined the Hun Tie Dan, which was half the time written on the Dan Fang.

This Hun Tie Pill is like iron, extremely dark, but there is a layer of light on the surface, although it is still a little rough, but this pill containing the qi of heaven and earth is very different from Peiyuan Dan.

In fact, the fifth-level Dan Fang and the first-two, three-and-four-level Dan Fang refined by the internal fire are very different in terms of efficacy, because they absorb the cultivator's Heaven and Earth Qi, and these Heaven and Earth Qi are constantly refined under the tempering of the external fire, forming the refined Heaven and Earth Qi.
