The earth fire burned for a while, and Shen Luo used his divine sense to check the situation of the Dan furnace, and felt that it was almost time to start condensing the Dan.

He used his spiritual power to continuously squeeze the spiritual liquid in this Dan furnace, just when it was about to be compressed.

The spiritual liquid suddenly dispersed, Ning Dan failed, and a burnt smell soon came out.

Shen Luo was not disappointed at all about this move, and it was the first time he had used the alchemy method of an immortal cultivator.

It was not surprising that he failed, after all, he didn't expect to succeed in the first alchemy.

So he turned off the earth fire first, and after the Dan furnace cooled down, he cleaned up the contents of the Dan furnace again.

A quarter of an hour later, Shen Luo once again placed a copy of the materials of the Zhuyan Dan in the Dan furnace.

As a result, the result of the second time was still the same as before, another smell of burnt paste came out, and the water turned into a pot of paste like boiled rice porridge.

The same was true for the next few alchemies, Shen Luo rubbed his eyebrows.

Using spiritual power to control water for a long time made him very tired.

He had been refining no less than ten times, and he had been stuck in the link of Ning Dan, he didn't expect that this water refining was the same as fire refining, and it was so difficult.

Originally, he wanted to avoid refining with water, and instead use the same as when he was refining in Heiqiongmen before, directly refining with fire.

But there was no turning back when he opened the bow, and he had to start all over again if he was refined, and he didn't have so many materials.

Thinking back on these Shen Luo pondered for a while, summed up the experience of previous failures, and then opened the furnace again.

Soon it was time for the Ning Dan link again, and Shen Luo was engrossed, with the soaring flames.

The magic tricks were drawn out one after another, and the milky white spiritual fluid shrank smaller and smaller.

Until it gathered into the size of a marble, it suddenly gathered in the center, and a pill took shape.

Shen Luo's face was happy, but he didn't dare to relax a little, his divine sense passed through the furnace.

I saw that the formed Zhuyan Pill was constantly rotating under the manipulation of his spiritual power.

This process lasted for about an hour, and the entire furnace was filled with mist, and the Zhuyan Dan, which had become half a circle, gently rose and fell in the mist.

Seeing this, Shen Luo couldn't help but be a little nervous, and the following is the most critical step to open the Dan.

Kaidan determines the number and size of the pill, and there are more materials for water refining than fire refining.

Coupled with the configuration of spiritual water, as well as the final spiritual absorption link, if it is opened well, it is very likely that a spiritual material will open several pills.

With a flick of his sleeve, he lifted the lid on the stove.

At this moment, the spiritual power around the Dan furnace, as if it had received some kind of suction, swarmed into it continuously.

Seeing this, Shen Luo also began to continuously inject his spiritual power into it.

The elixir was infused with aura, which made it a little larger.

Suddenly, the spinning elixir, as if it had absorbed the aura, suddenly paused.

After a while, it began to spin wildly, forming a cloud of phantoms!

Shen Luo stared intently, and then looked at it in surprise, three, there were actually three Zhuyan Pills.

I just didn't know what the quality of this pill was, as soon as he grabbed it, all three Zhuyan Pills fell into his hands.

Looking at the pill that fell in his hand, he found that this pill could only be said to be reluctant, three low-grade pills.

The quality of the elixir is mainly divided according to the content of impurities in the refined elixir, and the less impurities, the higher the quality of the elixir.

Just like the three Zhuyan Pills in Shen Luo's hand, although they are low-grade pills and contain some impurities, they can still be swallowed.

Whether it is a low-level or a mid-to-high-level elixir, it contains some impurities, although these things will not cause death if eaten.

However, it will remain in the human body and affect the functions of all parts of the monk's body, so long-term swallowing of the pill will easily cause vein occlusion.

The so-called medicine is poisonous, so few monks will take such a thing as pills often.

Unless there are no impurities in the elixir you are taking, and an elixir like this one that does not contain impurities, also known as the best elixir, has very strict refining requirements.

It is impossible for an ordinary Dan Master to refine it, and this kind of pill is probably only possible for someone at the level of a Dan Dao Grand Master to refine it.

Therefore, some capable monks, they will choose to buy higher quality elixirs, the higher the quality, the fewer impurities.

After all, the purpose of swallowing the pill is to enhance cultivation, and if it is because of the pill, it affects one's own cultivation speed, then the gain outweighs the loss.

Generally speaking, only pills with more than 30% medicinal power can be called true elixirs, that is, lower-level elixirs.

The medicinal power of the pill is divided into three, seven, nine, and ten, corresponding to the low-level, medium-level, upper-level, and superb, respectively.

At present, the best pill is already the highest level of pill known in the human world, and there is also an immortal-level pill above the best pill.

Like the immortal level elixir, it is generally only born in the spirit world or the fairy world, and when it becomes a pill, it will produce a pill pattern, and the more pill lines, the stronger the medicinal power of the pill.

The pill before the immortal level can only ensure that the pill does not contain impurities, and its medicinal power is also decent.

The pill that can really play its role depends on the immortal-level pill.

As for the division of the Immortal Rank Pill, it is unknown.

The alchemist of the human world, the medicinal power of the elixir refined.

It can achieve a three-percent medicinal effect, but it is the first glimpse of the door, this kind of Dan master is not surprising, any Dan master can do it.

Reaching seventy percent is to be able to comprehend it, and the Dan master who can refine this quality belongs to the backbone of the Dan Dao.

And once it reaches the medicinal effect of ninety percent of the heart, it is relatively rare, and it will immediately be regarded as a guest of honor by the major family sects.

Shen Luo looked at the pill in his hand and felt that it was useless to swallow this low-grade pill.

The efficacy of the medicine is too poor, no matter how you say it, you have to have a mid-level pill.

He didn't swallow the low-priced pill immediately, but just looked at it for a while, and then placed the pill in his mysterious gourd.

Now he doesn't have anything extra to store this elixir in a container, he can use this gourd to store it.

After placing the elixir, he began to continue refining the Zhuyan Pill again.

He now has a few materials left in his hand to refine the Zhuyan Pill, as for whether he can refine the mid-level pill in the future, it can only be said that it is up to fate.

Soon, a period of time passed, and Shen Luo sat on the futon very tiredly.

He didn't expect his luck to be so bad, since he had opened three low-level Zhuyan Pills earlier, the next few alchemy pills had all failed.

It is said that practice makes perfect, and if you refine more, you can find skills.

But he succeeded in more than a dozen materials, and he succeeded once, and the refining was still a low-grade elixir.

"Can I only swallow this low-grade elixir?" Shen Luo was very annoyed and unwilling.

In desperation, he could only take out the gourd and prepare to swallow this low-level elixir.

Although the sparrow is small, it is also meat, although the grade is a little lower, but it is not that it cannot be eaten.

As soon as he opened the cork of the gourd, he smelled wisps of the fragrance of the elixir emanating from it.
