Returning the Corpse Alchemy Technique to the Sumeru Illusion Ring, Lin Feng stared at the three leyline fires in the alchemy room, and as the flames jumped up and down, a bold idea gradually sprouted in his mind.

Since He Zheng and Fang Yuan are dead, and Xiao Heng has also left the Qingdanmen rudder, even if there is a dark line of the Yin Demon Sect in Dusk Cloud City, I am afraid that no one will pay special attention to Lin Feng's movements. Because since He Zheng came to deal with Lin Feng in person, it means that he is the only person who knows about this matter, as long as Xiao Heng does not return to Qingdanmen to divide the rudder, Lin Feng should be safe.

Now that he couldn't get out, Lin Feng simply took up residence in the rudder in the name of the Qingdanmen Medicine Refining Disciple. Anyway, before Shi Hongye left, he had already left a copy of the espionage, and with this espionage, Lin Feng justifiably became the steward of the Qingdanmen rudder.

In the days of war and chaos, cultivation was not at ease at all, and Lin Feng happened to take this opportunity to improve his alchemy skills with all his might, and strive for a breakthrough in the Dan production rate.

The Dan rate is divided into ten percent, in fact, it is difficult to improve after the seventh percent, relatively speaking, the first three percent is relatively simple, and from the fourth percent onwards, it takes years of perseverance, countless circular practices, in order to have a trace of graduality, so the alchemist with the Dan rate of fifty percent is much higher than the alchemist below fifty percent in terms of identity!

And Lin Feng wanted to increase the rate of output to fifty percent, not for the sake of any gorgeous false name, but because the fifty percent rate of output has changed qualitatively compared to the rate of forty percent in essence!

In the Danshu, the Dan rate is a strange and strange thing, the same material, if there is a fifty percent Dan rate, then the probability of the finished Dan and the waste Dan are five or five, but if there is only a forty percent Dan rate, then the success rate of the finished Dan is not a simple forty percent, but linked to the alchemist's enlightenment Dan!

The higher the level of the Enlightenment Pill, the greater the increase in the efficiency of the Pill Pill. Lin Feng's Dan Art is currently at the level of a craftsman, which means that the elixir he can refine can only stay at the elixir taken by the monks in the foundation building stage at most, and as for the elixir in the Dan stage, he can't refine it anyway. []

And on this basis, his Dan rate is currently only forty percent, and it is also calculated according to the elixir of the Essence Enhancement Pill.

For most alchemists, it is generally necessary to increase the pill rate first, and then they can increase the level of the pill technique, unlike Lin Feng, who goes against the grain. Most people start as an alchemy apprentice, and at the beginning they can only choose one kind of elixir for refining.

When the Pill is successfully refined, the Pill is taken as the mother, and the rate of Pill is increased day and night, and once the Pill rate reaches ninety, one step further can enter the level of alchemist.

On this basis, alchemy apprentices can refine the elixirs used by the monks of the Xuanzhao period, alchemists can refine the elixirs used by the monks of the Qi cultivation period, and alchemists can refine the elixirs needed by the monks of the foundation building period. However, there is one point, that is, the pills they can refine are only one type at the beginning, not all categories!

Elixirs are generally divided into four categories, consolidating the foundation and cultivating the yuan, supplementing and restoring, warding off evil spirits and detoxifying drugs, and special classes, each type of elixir has different techniques and refining systems, so when choosing the Kaiqi Dan, everyone must have a key tendency, because the future Dan rate is based on the Kaiqi Dan.

If an alchemy apprentice chooses the Hui Ling Pill as the target for the trial, when he refines the first furnace of the Kai Qi Pill, then his initial pill rate is generally set at about one thousandth, that is to say, refining a thousand furnaces of the spirit pill is possible to produce a finished pill!

Of course, if there is enough elixir support, the pill rate at this time is easy to increase quickly, and most alchemists can quickly break through to the level of one percent, and then through the accumulation of practice, they can increase little by little.

When the alchemy apprentice's Dan rate breaks through to the fifth percent, then the Dan rate of its other elixirs will automatically float to the level of one thousandth, which is the basic feature of practice makes perfect in Danshu skills, because there are too many techniques that can touch the class, so there is this subtle internal connection between the four major types of elixirs. [~]

When the alchemy apprentice's output rate reaches more than ninety, he may be advanced to an alchemist by chance. This kind of transformation requires a variety of factors to promote each other, including opportunities, qualifications, heavenly opportunities, epiphanies, etc., and individuals cannot force it.

After the alchemy apprentice advanced to an alchemist, the output rate of the low-grade Huiling Pill naturally reached more than ninety percent, and the output rate of the medium-grade Huiling Pill was initially one thousandth, and this value can still be increased to about one percent in the short term, of course, the premise is that there are enough elixir materials for practice.

However, there is one point, the output rate of the other three types of elixirs at this time cannot be accurately measured. The specific values are closely related to his usual practice of these three types of elixirs, as well as his personal qualifications.

Generally speaking, if he hadn't practiced anything, then even if the recovery elixir had reached the alchemist level, the pill rate of the other three types of elixir would only be between one and twenty percent at most.

Taking Xiao Heng as an example, the rate of his Peiben Guyuan elixir has reached fifty percent, and his rank is an alchemy craftsman, which means that when he refines a high-grade Guyuan Dan, one of every two furnaces will be successful. However, if he was allowed to refine other kinds of elixirs, the rate of pills would not be so high.

However, with the increase of the level of the Dan Master and the Dan production rate, other types of elixirs will be imperceptibly increased due to the inherent contact bypass, even if they do not go through special practice, but the effect is very low.

Because Lin Feng was doing the opposite, although he had the level of an alchemy craftsman, it was a pity that the pill rate was very low. His forty percent pill rate at this time was completely calculated according to the elixir of the Essence Enhancement Pill.

Since the Essence Strengthening Pill is a special type of elixir, it is more complicated in terms of alchemy techniques, it stands to reason that it is only taken by monks who meet the stage of Qi cultivation, but if you want to refine it, you need the level of an alchemy master to complete it!

In addition to the Essence Strengthening Pill, Lin Feng is currently blank in the Dan rate of other kinds of elixirs! Only the Hui Ling Pill that he often takes, after a hard trial a few days ago, finally broke through the one-percent Pill rate, of course, it is only a low-grade one, as for the high-grade Huiling Pill, the current Pill rate is less than one percent!

What Lin Feng wanted to do now was to use the leyline fire in the alchemy room to accelerate the increase in the pill production rate of the four major types of elixirs. Because of the Dan art of the level of an alchemist as a foundation, it is naturally much easier for him to improve, plus the immortal net and the Sumeru Illusion Ring provide him with a steady stream of elixir materials, which is bound to achieve twice the result with half the effort.

The only purpose of improving the Dan Art in the alchemy room is to use the fire of the leylines here to save a lot of Origin Spiritual Power! Although Lin Feng's immortal net can provide him with firepower to refine the spirit pill,

But the premise was that a large amount of primordial spirits had to be consumed to induce that red flower, and the few primordial gods that Lin Feng had captured so far were not even enough to induce the elixir, so it was undoubtedly a wise move to use the fire of the leyline.

In the next few days, Lin Feng stayed in the alchemy room without leaving home, using the various elixirs that had matured in the Sumeru Illusion Ring to try to refine all kinds of elixirs.

On the seventh day, Lin Feng opened the door of the Qingdan Gate rudder, and at this time, the streets and alleys of Duyun City Fang City were full of monks, and most of them were worried, confused and depressed.

In these seven days, Lin Feng refined countless waste pills, and consumed thousands of elixirs, but the number of times the finished pills appeared was simply a handful. And in order to ripen some elixirs, Lin Feng had already used up the three primordial spirits of the foundation building stage cultivators!

At such a rate of consumption, the few Yuan Gods remaining in the immortal net would soon be consumed, and Lin Feng would certainly not be able to use them all up in order to keep a back hand for himself.

With the situation in Dusk Cloud City at this time, it would definitely not work to buy demon pills, and the major markets would raise prices to ten or even dozens of times the usual price, even if Lin Feng was lucky enough to buy a few, it wouldn't take long to run out.

The simplest and most direct way is to use ready-made elixirs for alchemy, so that there is no need to consume the primordial spirit in the immortal net to ripen the elixir. Therefore, Lin Feng decided to restart the elixir training business of the Qingdanmen rudder, and he was the new alchemist!

Different from the previous regulations, the announcement posted by Lin Feng was that only one person was accepted to enter the alchemy at a time, and the magic circle of the Qingdan Gate rudder had been slightly transformed by Lin Feng, and he could control the opening and closing of the magic circle through the magic trick in the alchemy room.

If someone needs alchemy, he opens the magic circle and invites it in, and the materials are placed in the utensils in front of the alchemy room, and then that person can stand in the courtyard and look at Lin Feng, while Lin Feng has his back to him,

There is still a magic circle in the alchemy room, it is difficult for outsiders to enter, but they can clearly see the situation of the Dan furnace, as long as there is a finished Dan furnace, Lin Feng will not want to deceive them, but once the refining is wasted, they can only consider themselves unlucky.

No matter what success or failure, after each furnace, Lin Feng would invite the previous guests out, and then open the magic circle to welcome the next visitor, and the cycle continued endlessly. And Lin Feng knew that his pill rate was currently too low, so he only charged one percent of the refining fee, and of course he didn't take a penny after refining and scrapping, and even some rare elixirs, he would also take out some spirit stones as compensation.

However, despite this, since he only had the strength of the eighth layer of the Qi cultivation period, and he was unknown in Dusk Cloud City, there were many monks who came to him to practice on his behalf, and occasionally a few people came to the door, but most of them ended in failure, Lin Feng's reputation gradually became outside, and the people who came to refine the pill became even rarer.
