This is not the first time Qiao Kun has met the Three Emperors, but he has not seen the Three Emperors a few times before. At this time, his cultivation and knowledge improved, and he had more ability to detect calamity, and he found that there was a strong calamity behind the Three Emperors.

The Three Emperors sat in the Huoyun Palace, and the operation and cultivation were to suppress the calamity here.

That calamity qi is so thick, ordinary calamity materials, such as the calamity on Huang Feihu's body, are only a drop in the ocean. If it escapes from the world, I am afraid that the danger and tragedy of the Great Tribulation of the Gods will increase by more than fifty percent.

Why? Why suppress the calamity? Qiao Kun thought to himself, could this be the reason why the human race occupies the fertile land? Is it that the Three Emperors have been suppressing the calamity here and carrying the burden for the human race?

At this time, the Shennong clan had already spoken, "I have only heard of the Falling Immortal Pill, but I have never seen it, so I may not be able to understand it." "It's not very sure.

However, Shennong's was still amiable, and beckoned Qiao Kun to step forward, "Child, come here, let me take a look." ”

Even the Shennong clan is not sure to solve this elixir? Qiao Kun stepped forward and came to Shennong's side. Shennong's hand grabbed Qiao Kun's wrist, as if it was a pulse. But Qiao Kun could feel a trace of breath coming out of Shennong's fingertips.

This breath is peaceful, with the medicinal power of herbs and trees, which can warm and nourish the body. But it makes people feel very comfortable.

After some exploration, Shennong said with a smile: "This Meteorite Immortal Pill has refined the power of the five decays of heaven and man, which can affect the balance between the True Immortal Law Body and the Golden Immortal Law Body and Heaven and Earth, and there are different changes according to the different Law Body and Law Body, it is difficult to solve it through a pill, I am afraid that it is the 'Yi Pin' in the Dan." ”

The five decays of heaven and man? Best? When Qiao Kun heard these two words, he couldn't help but sigh in his heart, the Meteor Immortal Pill was really good.

Now that Qiao Kun is not bad at cultivation, he naturally knows what the five decays of heaven and man and Danzhong Yipin represent.

After the Qi practitioner cultivates the True Immortal Dharma Body, the Dharma Body compromises with the balance of heaven and earth, and the state is always adjusted to the best, and the winning body is subtle, light and clean, and does not provoke fine dust.

However, when the longevity is about to end, the true immortal law body compromises and destroys heaven and earth, and there will be "bad clothes, wilted crowns, sweat comes out, Zhong Le stops, and this seat leaves" and other five decay powers, which are called the five decays of heaven and man.

And the golden immortal is the existence of the same longevity as heaven and earth, but if the compromise with heaven and earth is broken, there will still be five decays of heaven and man.

These five decaying immortals avoided it, and Lu Yue was able to refine the power of the five decays of heaven and man into the Dan, no wonder even the golden immortals couldn't resist it.

As for the "Yipin" in Danzhong, it is also very good.

Dan has gods, spirits, and wonders, among which the best pill is actually a "divine product", the so-called Nine Turns Zijin Pill is a divine product, which is the best that people, immortals, and gods can do.

However, there is also a kind of elixir called "Yi Pin", which may not necessarily be stronger than the elixir of spirit, god, and wonderful product just because of the effect, but it is a little special and is not in the grade evaluation.

This elixir is not forced, even if you do everything to the best, you may not be able to get it, it is out of intention, it is obtained from nature, it is possible to get a little favor from God, and it is possible to complete it.

Therefore, this can also be regarded as the completion of God's hands, which can be met but not sought.

Since this Meteorite Immortal Pill is a "masterpiece", the quantity must be limited, and if Lu Yue is allowed to refine it, he may not be able to refine it.

Shennong sighed again: "This elixir may not be incomprehensible, but I can't afford it now." ”

It seems that the Falling Elixir is not something that the Shennong Clan can break easily. Qiao Kun hurriedly said, "I really don't dare to trouble the Three Emperors." ”

Now he noticed that the Three Emperors were suppressing the robbery, and he also felt that he really shouldn't bother the Three Emperors for his trivial things.

Shennong smiled: "It's not a trouble, it's just that it's really not idle." In this way, we will teach all the medical Tao and Dan Dao, how about you detoxify yourself? When you can untie the elixir of the Meteorite in yourself, you can also help Li Min. ”

Hearing this, Xuanyuan agreed: "That's very good. ”

Do you detoxify yourself? Qiao Kun thought in his heart, when will he learn?

He thought that he had a lot of medical knowledge shared by the lotus incarnation, and he also had 100,000 heavenly soldiers and "easy to change" to help, so he agreed. Anyway, it's safe enough in the Fire Cloud Cave.

Seeing that he agreed, Shennong gave a jade ruler and said, "In this case, I will teach you the "Shennong's Materia Medica". You have to be good at life and practice. ”

This jade ruler is more than three feet long and more than two inches wide, it looks like an ordinary ring ruler, and it looks like it is composed of emerald green jade, and there are mysterious runes on it, densely packed.

"Shennong's Materia Medica"? Qiao Kun solemnly kowtowed to the Shennong clan, and then respectfully stretched out his hand to take the jade ruler.

As soon as the treasure was in his hands, Qiao Kun realized that it was not actually made of jade, but made of special wood, with a warm and smooth texture, and Qiao Kun felt a trace of medicinal qi entering his body from the jade ruler, and the warm medicinal qi constantly nourished his body and made him feel very comfortable.

Shennong smiled: "This is my imitation of the Shennong ruler, and the "Shennong's Materia Medica" is in it. ”

It turned out to be a large piece of jade. When Qiao Kun heard this, he sank his mind into this pseudo-Shennong ruler, and found that this ruler really had the function of jade slips, which contained countless information about medical Taoism, Dandao, and medicinal materials, and these information together constituted a classic.

I don't know how long it took, Qiao Kun finished his realization and withdrew his mind. This is the "Shennong Materia Medica", but it is not perfect, only the first three.

The first three articles only introduce medicinal herbs, which are varied. According to the heaven, earth, and people, it is divided into three products, and each product has a variety of plants, trees, jade, and insects, among which plants and trees are the most.

All the herbs have a picture that makes it easy to understand, and there are also medicinal properties, characteristics, treatment methods, etc., and some herbs also provide methods for cultivation. This is more detailed than what he learned with Mingyue when he was singing in the court. Even the first three articles are very good, and if they reach the world, they can help many people.

Thinking of this, Qiao Kun is a little strange, there is so much knowledge of herbal medicine, why hasn't it been passed on?

Of course, these were not enough for him to unlock the Meteorite Elixir, after all, this was only the first three articles of the "Shennong Materia Medica", which only introduced herbs, and most of them were ordinary human herbs, and some even had few spiritual energy.

However, Qiao Kun was not impatient, it was originally to be gradual, and it was of course useful to learn more ordinary herbs.

At this time, Fu Xi saw that he was awake, and said to him again: "You have a lot of karma on you, and staying here is a little hindering to my Huoyun Cave, so let's go into my river Tuluo Book first." After that, he summoned the book of Hetuluo.

The Hetu Luo book glowed and turned into a kind of gossip look.

Is this for fear of being found out some clues? Of course, Qiao Kun is willing to cooperate. At the moment, he urged the body method and turned into a streamer and entered the gossip.

Then he entered a piece of heaven and earth, in which there were heaven and earth, wind, thunder, water, volcanoes, and rivers, but these eight things were not independent, but connected, and they were entangled with each other and produced some new changes.

If Qiao Kun has an understanding, this is the deep meaning of gossip and sixty-four hexagrams.

The Hetuluo Book contains all kinds of mysteries of gossip, and when he entered it, Qiao Kun felt that there was a lot of information in it, and some of it was beyond his understanding of gossip, and even beyond his understanding of the sixty-four trigrams.

Some comprehensions of the five elements of yin and yang, as well as the chapter of "Crossing Yourself", have been verified. It's like there is a higher level of understanding, and a higher level of people are leading him, standing on a higher place to measure.

Is this the realm of Emperor Xi? Qiao Kun admired in his heart, these realizations were very useful to him and to the progress of Yitu Tongchang.

He vaguely felt that there was something acting on him that could conceal cause and effect, and if he hadn't now directly known the "Dao" and had a deep understanding of the "Dao", he might not have been able to sense it.

Soon Qiao Kun came out of the Yitu change, and Xuanyuan taught another volume of "The Yellow Emperor's Inner Canon".

Fu Xi came in with the water and fire boy and led Qiao Kun down to rest.

The internal space of Huoyun Cave is huge, and there is naturally Qiao Kun's residence. But it is a small wooden house on the edge of Zizhi Cliff.

Zizhi Cliff Fairy Grass, Spirit Grass, Fairy Fruit, and Spirit Fruit are everywhere, and there is a hundred-acre medicine field next to it, in which there are all kinds of medicinal herbs.

When the water and fire boy left, Qiao Kun pondered "Shennong's Materia Medica" with peace of mind. After all, the Meteor Elixir is a good product in the Dan, and there should be no specific antidote. If he wants to remove the effect of his Falling Elixir, he must find a way by himself.

The first three articles of "Shennong's Materia Medica" contain thousands of materials, with different shapes, medicinal properties, colors, and tastes. The effects are also different, from antidiarrheal drugs, anesthetics, antipyretics, cough and asthma.

Of course, it is not limited to curing diseases, there are also some poisons that can make people hallucinate, diarrhea, numbness, discomfort and so on.

The first three articles are a threshold, and if you want to go further and learn more advanced knowledge, you need to take an assessment.

In addition to the shape, color, aroma, and medicinal effect, the time, method, treatment, and preservation methods of harvesting are all different, and they all need to be carefully memorized, which is naturally difficult.

But Qiao Kun has 100,000 heavenly soldiers and gods to help him and memorize all the content of the first three articles.

However, he knew that his purpose was to detoxify, not to pass the assessment, so he was not in a hurry, and combed through the "Shennong's Materia Medica" against the drugs in the medicine field.

Familiarize yourself with the appearance and smell of the drug, and also swallow the drug to familiarize yourself with the properties, power and effect on the body.

After doing it, he took out Chen Geng's jade slip, familiar with the toxicity of drugs, so that theory is linked to practice, but in more than ten days, he has a thorough understanding of thousands of drugs and successfully passed the assessment.

Of course, this is not fast, counting the time in the illusion world, in fact, he has been studying for more than three years.

After passing the assessment, the emerald green pseudo-Shennong ruler passed a trace of breath to him, but it was the fourth article of "Shennong's Materia Medica".

This fourth article is not a new drug, but talks about pharmacology, as well as the combination of drugs, the effect of combination, and the interaction of drugs. Although the concept of the monarch and the left envoy has not yet been proposed, it has a combination of weights and various pharmacological knowledge.

After the completion of this fourth article, a new round of assessment was conducted, and the questions presented this time were a little difficult, and the test was about creation.

Most of them are case analysis questions, for example, if someone has some kind of discomfort and some symptoms, how to choose drugs at this time. Qiao Kun can also clearly see the various manifestations of the patient, even the pain.

This is not only the knowledge of herbology, but also the knowledge of medicine.

Medicine is so profound that sometimes the same symptom is actually different diseases, and some even the same disease requires different treatment options.

If you only rely on the knowledge of "Shennong's Materia Medica", it is difficult to pass the assessment.

However, after all, Qiao Kun has the "Yellow Emperor's Inner Canon", as well as the experience shared by the lotus incarnation, combined with the "Easy Map Change" and the 100,000 Heavenly Soldiers and Gods, but also sorted out the characteristics of many diseases and completed the assessment.

At the beginning of the fifth chapter of "Shennong's Materia Medica", some fairy grasses, poisonous weeds, fairy fruits, and poisonous fruits are involved, and there are thousands of types, which are not less than ordinary medicinal herbs.

Most of the many fairy grasses and fairy fruits that Qiao Kun had seen before could be found in this "Shennong's Materia Medica".

Of course, there are a small number that are not mentioned. For example, there are no laurel trees on the Moon Palace, peach of the Queen Mother, ginseng fruit, Huangzhong plum, etc. I think that the Shennong clan has never had the opportunity to taste it.

The effects of fairy grass and fairy fruit are varied, such as healing, enhancing mana, enhancing qi, etc., and there are more fairy fruits with more fancy effects, such as no Gu, worried, wart, not hungry, not drowning, taking off, resisting fire, resisting wind, and so on.

There are also many fairy fruits that have obvious side effects, which are immediately fatal after eating, and some will be worried, irritable, comatose, feverish, and so on after eating.

Although the number of fairy fruits, fairy grasses, poisonous fruits, and poisonous weeds is only the same as that of mortal grasses, there are more details to memorize. How much more complex than ordinary herbs is 10 times higher?

The sixth article is the medicinal interaction between fairy grass, poisonous weeds, and fairy fruits, how to have an effect on people, and the amount of matching.

The seventh article talks about alchemy, first introducing the key points of alchemy, and then the treatment of drugs and the techniques of alchemy. There are also many basic elixirs. It can improve cultivation, increase mana, strengthen the body, treat injuries, and so on.

There are many points in alchemy, but it is a comprehensive knowledge. For example, the treatment of immortal materials, different ways will have different effects, which should be studied together with the fifth article, and as for the matching of immortal materials, it should be studied in conjunction with the sixth article.

There is also the control of the heat, the application of talismans, the interaction of drug properties, etc., which are very complicated.

And this alchemy is different from others, it is not just about knowing, it also needs to be practiced continuously. Otherwise, it is very likely that the brain has learned, but the hand has not. This is called "knowing what it is, knowing why it is, but not being able to." ”

There are only seven articles in "Shennong's Materia Medica", and at the end of the seventh article, there is a passage from Shennong's family.

He said that the fairy grass and poisonous weeds in this world are so vast that even he can't explore them all.

The combination of medicines, with different heat conditions and different talismans, produces different effects, which is even more profound and profound, and he does not dare to say that he is proficient.

And Qiao Kun is even worse, for half a year, he has been taking all kinds of fairy grass and poisonous weeds according to his own situation, linking theory with practice, and he can only understand Xiaocheng.

However, with his unremitting efforts, the cracking of the Meteoric Elixir has made a lot of progress.
