In the cave, the fragrance was fragrant, and Lin Feng sat on the ground, with a little beads of sweat on his forehead, and his expression was slightly tired. However, at this moment, his face was filled with excitement.

Looking at the five round black pills in his hand, there was a look of relief between his eyebrows, and the efforts of the past few days were finally not in vain.

This elixir is called 'Qi Gathering Pill', which is a common basic pill used to increase spiritual energy, but the grade of the pill is too low, and it is only suitable for Qi Gathering Realm monks.

Although this elixir had no effect on Lin Feng, he was still full of joy when he looked at the elixir, as if he was looking at a treasure, after all, this was the first elixir he had successfully refined.

"Strange, I heard that they only have one pill in each furnace, why can I refine five?" Lin Feng said to himself, although he had not seen how other alchemists did alchemy, he had heard Song Hang say this.

Moreover, it is also recorded in the Dan Dao basic book given to him by Song Hang that every time he alchetes, there is only one piece in one furnace, and as for those excess dregs, they will turn into residues and crumbs, sink at the bottom of the Dan furnace, and turn into ashes.

This is the benefit of practicing the Holy Spirit. Yu Xuan in the Holy Emperor Ring explained: "Because of the Holy Spirit, your aura is purer than most people, and the herbs are nourished by the pure aura, and some useless medicinal residues can also be used.

To distinguish whether an alchemist is powerful or not, in addition to seeing what grade of pill he can refine, it also depends on the degree of use of medicinal herbs.

When a little skilled, he can use two or three percent of the medicinal effect, a real Dan Dao Grandmaster, can use the effect of medicinal herbs to the eighth or even ninth layer, as for the ten layers of medicinal effects, such an alchemist is probably unique!"

Although Yu Xuan had no opinion on Dan Dao, she was well-informed after all and knew some divisions within the alchemist. Moreover, since letting Lin Feng start alchemy, she has also been flipping through a large number of ancient books.

In the Holy Emperor Ring, not only her and Yu Rou are the two sisters, but there are also many classics, which are themselves prepared for Lin Feng. However, a person's energy is limited, and Lin Feng can't learn everything, so he needs Sister Yuxuan to choose it for him.

This is also the reason why Yu Xuan was able to give the ghost spirit cat a lot of mastery about cat spirit beasts at the beginning.

However, although there were many ancient books in the Holy Emperor Ring, it was difficult for Yu Xuan to pick out the ones that were helpful to Lin Feng, because Lin Feng was too ignorant of Dan Dao and knew nothing at all.

Most of the ancient books of Dan Dao here are special alchemy methods, or some rare Dan prescriptions, as for the Dan prescriptions that are too ordinary and common, and can be seen everywhere, there are no Dan prescriptions here, so she needs to go to Song Hang to borrow the basic books of Dan Dao.

After listening to Yu Xuan's explanation, Lin Feng nodded, about the use of medicinal effects, Song Hang's book did not mention it, but he could also understand it, after all, this book only records the basics, and only alchemists who have passed the basic stage will consider the issue of medicinal efficacy.

"Then these few pills I refined have exerted several layers of medicinal herb effects?" Lin Feng asked.

"There are probably three layers!" Yu Xuan judged after looking at the color of the elixir.

"I refined five pieces to exert the effect of three layers. Lin Feng looked down at the pill in his hand and whispered slowly.

However, Yu Xuan shook her head directly when she heard this, and corrected: "It seems that you have misunderstood what I meant." ”

Lin Feng was taken aback when he heard this, and looked at Yu Xuan in puzzlement, he didn't understand what he meant, she didn't say it herself just now, looking at the extent to which the medicinal materials were used, she could also judge the effect of the pill!

Seeing Lin Feng's puzzled expression, Yu Xuan explained again: "Although the number of pills can also determine the degree of your use of herbs, what is more important is to see how many layers of medicinal power your pills can exert.

The medicinal power of the pill is too poor, even if the quantity is too large, it is useless, but generally speaking, the more pills that can be refined at one time, the stronger the medicinal power will be, because only by making good use of the herbs can you refine multiple pills. ”

Seeing that Lin Feng still didn't seem to understand, Yu Xuan said in more detail: "It's like a beginner, he can only refine one pill at a time, and the medicinal power of this pill is only less than half a layer.

And you have refined five pills, and each pill can exert three layers of medicinal power, that is to say, any of your five pills, its medicinal power is six times that of his. ”

"I see. After Yu Xuan's detailed explanation, Lin Feng finally understood the distinction between the medicinal powers.

A true alchemy master, every pill he refines, its medicinal power can reach the height of the ninth layer, this medicinal power is equal to three times that of Lin Feng, and if it is about value, it is not as simple as three times.

In the mundane world, there has always been a saying that medicine is poisonous, and such a saying also exists in the monk world. The elixir is to extract the essence of a variety of herbs and elixirs and fuse them with each other to maximize the power of the medicine.

At the same time, it is also reducing the 'toxicity' contained in the herbs and elixirs themselves, the more high-level the elixir, the lower its side effects, so compared with a pill with a nine-layer medicinal power and a pill with a three-layer medicinal power, the price difference is dozens or even hundreds of times.

Yu Xuan looked at the medicinal residue poured out of the Dan furnace and explained: "The Dan furnace stands on three legs, implying three births and all things, and the elixir refined by it is also in line with this characteristic.

When an alchemist can only use less than one layer of medicinal effect, there is only one elixir, and when he can use two layers of medicinal effect, there will be three elixirs, and when he can use three layers, there will be nine elixirs.

And so on, with each additional layer of potency, the number of pills will increase by multiples of three, until the fifth layer. An alchemist who can use the effects of the five layers of medicine can refine a total of eighty-one pills in one furnace.

However, when the six-layer medicinal effect can be used, only twenty-seven pills can be baked in one furnace, and when the nine-layer medicinal effect can be used, it is the same as the alchemist with one layer of medicinal effect, and only one pill is baked.

There were originally nine pills in your furnace of pills, but it was only because of your control of the heat and the questions inside the pills that only five of them were successfully baked.

And your first alchemy, and looking at the color of your pill, obviously did not use the seven-layer medicinal effect, so I said that you are a three-layer medicinal pill. ”

Yu Xuan explained in detail, Lin Feng understood it completely this time, he looked at the medicine residue on the ground, and began to think in his mind, what was wrong with the shortcomings of the alchemy just now, which caused these four pills to turn into medicine residue.

A quarter of an hour later, Lin Feng regained his spirit and began alchemy again. Because of a successful experience, this time the alchemy was much easier, and some of the previous problems were also solved this time.

Three hours later, the pill was formed, and the incense came to the face, making the entire cave filled with fragrance. Relying on the purity of his own aura and the strength of his divine sense, this elixir still has three layers of medicinal power, and due to the reduction of mistakes, seven pills were successfully released in this one.

There were still three copies of the materials for the Qi Gathering Pill, and Lin Feng worked hard to refine them all, and the first two times were successfully refined, and seven pills were released.

However, due to the fact that alchemy was very draining, when refining the third furnace, Lin Feng's spirit was already a little sluggish, and during the refining process, due to lack of energy, an negligence, the furnace was blown up again.

"Alas, let's take a rest first!" He has been refining for more than ten hours in a row, even if he has cultivated the Star Introduction, his divine sense is far beyond that of ordinary people, but he can't withstand such a toss.

Sitting cross-legged with his eyes closed, Lin Feng did not rest with his head down, but was running the exercises, the more tired he was, the better the effect of the exercises, although he was physically and mentally exhausted, he still persisted.

An hour later, Lin Feng opened his eyes, and the materials for the Qi Gathering Pill were gone, so he could only start refining another Blood Gathering Pill.

This is a kind of elixir used to heal injuries, and it is also a very common healing medicine, but it is the same as the Qi Gathering Pill, because the grade of the pill is too low, the healing effect is limited, and it is generally limited to the injuries caused by Qi Gathering Realm monks.

This healing medicine could be said to be completely useless to Lin Feng, because it was already difficult for the Qi Gathering Realm cultivator to cause harm to him, and the injuries he suffered were far beyond the scope of the pill that could be treated.
