During this time, Qin Yan had been thinking about a problem: how to develop the decoction formula used to improve cultivation after the late stage of the Immortal Martial Nine Heavens.

Obviously, this is more difficult than imagined.

Both the Immortal Martial Realm and the Divine Realm have prescriptions for quickly improving cultivation, but these prescriptions are all obtained after tens of thousands of years or even longer, and they have been tempered by countless generations.

In fact, whether it is a prescription, a mental method, or a combat technique, the general situation is the same: before the primeval times, these things did not exist, and at that time there were no peerless powerhouses such as Pangu and Nuwa, and human beings were at the bottom of the food chain, and their survival conditions were extremely difficult.

However, humans have wisdom that other creatures do not have, even powerful demon beasts and divine beasts have high intelligence, but in terms of creativity, they are far from being comparable to humans.

Human beings living at the bottom of the food chain have slowly developed a cultivation system for later generations through the slow exploration of countless generations, slowly moving from low to high. As human beings have become more powerful, their status in the natural world has become higher and higher, and they have finally become the existence at the top of the food chain.

The same is true of drug formulas, which have been studied and explored from generation to generation, even if Shennong's prescriptions are different from those of others, it is not entirely what he can do alone, because before he developed the prescriptions, he must have understood all kinds of medical science and pharmacology, and those are all from his ancestors.

Shennong tastes a hundred herbs, this is not a myth and legend, but a historical fact.

At that time, Shennong already had a powerful cultivation, and he found that the existing decoction recipe and the medicinal materials he chose were too precious.

So, through countless exploration experiments, he had a secret book that was passed down to Qin Yan: using relatively low-level medicinal materials to prepare a decoction with the same effect.

How many years did Shennong live?

Qin Yan learned through Tu Wanxiong that once he surpassed the Immortal Martial Martial and reached the Heavenly Martial Rank, the lifespan of human beings would be as high as thousands of years. Like Shennong, a strong man who has reached the six heavens of Tianwu, the long life span is even more amazing, he used such a long life, with the help of powerful cultivation to personally test the medicine, and inherited the medical and pharmacological knowledge of his ancestors, and finally had this dazzling prescription.

What about Qin Yan?

First, he didn't have thousands of years to experiment.

Secondly, he didn't have the strength to test the drug.

With his current cultivation, some drugs are likely to cause death if they are consumed, and after the new drugs are compatible, they are likely to become deadly poisons.

What's more, Shennong had strong enough strength and spent so long, but in the end it stopped at the late stage of the Immortal Martial Nine Heavens.

What kind of ability does Qin Yan have to think that under the condition of insufficient strength and time, he can complete the follow-up prescription research that Shennong has not completed?

But!

He knew very well that he would never give up easily, and of course he would not spend all his time on follow-up prescription research, because he had more to do. Even, as time passes, his cultivation will become higher and higher, and even if he really researches the follow-up drug formula, he may not be able to use it.

However, this kind of prescription does not have to be used by oneself, and once it is successfully developed, it is not one person who will benefit, but the entire Anthropocene realm.

In this way, the strength of the human race will rise, and it will have an advantage in the battle of gods and demons.

Because he knows very well that more than 10,000 years have passed since the first battle of gods and demons.

In the past 10,000 years, the strength of the human beings on the earth has not improved, but due to the fall of the primeval powerhouse, it is likely that the strength is not as good as it was back then. On the other hand, the technology of the alien invaders is constantly evolving, although North also said that when it comes to the level of the Alpha Star, it will take 100,000 or even millions of years to upgrade to a level, but who can be sure that one day in the future, they will not be upgraded to a higher level?

Sailing against the current, if you don't advance, you will retreat.

If humanity can't find a way to develop, with the passage of time and the continuation of the war, the gap with Alpha will one day widen.

In the end, it is impossible to escape the fate of being enslaved or completely wiped out!

The difficulty of developing a higher-level drug formula is beyond imagination, but Qin Yan clearly knows that he has no choice.

Moreover, he could also be sure that higher-level prescriptions definitely existed, because according to Shennong's prescription, the preparation could reach the Ascension Divine Powder in the late stage of the Immortal Martial Nine Heavens, and the main medicine needed was only the best treasure-level medicinal materials. In this vast wilderness, there are also higher level immortal medicinal materials than the best treasures, and the medicinal effect of immortal medicinal materials is stronger, which means that higher-level drug formulas exist.

It's just that......

The immortal medicinal materials divided into three, six, nine and other categories add up to more than two hundred kinds in total.

First of all, it is very difficult to determine the main drug of the new formula from these medicinal materials. But in comparison, it is even more difficult to find a formula adjuvant, because the adjuvant does not have to be an immortal medicinal material, just like the Ascension Powder has a non-grade medicinal material that can be bought in any Chinese herbal medicine store on the earth.

What does this mean?

The main drug only needs to be found in hundreds of medicinal materials, while the auxiliary drugs have to be screened in different levels, a total of thousands of medicinal materials.

In this process, all that can be relied on is the pharmacological knowledge given by the ancestors, but there is no prescription to learn from, and everything has to be tried and screened by yourself.

Difficult!

Difficult!

Difficult!

However, in the end, Qin Yan still had a definite idea.

The first thing is to remove herbs that cannot be used as main drugs and adjuvants through deep knowledge of pharmacology. Then, with the help of pharmacological knowledge, as well as the understanding of the energy form and body structure of human warriors, the most likely formula was combined to try.

Take Ascension Powder as an example, if all the medicinal materials are separated, they each have different attributes and curative effects, so what can add up to improve cultivation?

This is definitely not a coincidence, but there is a certain reason for the drug to be born.

Shennong must have been the same at the beginning, first through pharmacological knowledge, to determine the formula that he thought was most likely to be close to the real one, and on the basis of this formula, he continued to change it through practice.

In the past, Qin Yan had to do all this by himself, but now Lou Yuqing has inherited the mantle of the Twelve Witch Ancestors, and his understanding of high-level pharmacological knowledge is not much different from Qin Yan's: the so-called one person is short and two people are long, and the so-called men and women are not tired of working together, so in addition to exploration, the young couple devoted themselves to the initial research of new drug formulas in their leisure time.

Due to the fact that the young couple had to study the formula together, the two groups of people that were previously divided had to be changed, Lou Yuqing and Qin Yan were in one group, and Lu Qingyun was transferred to Tu Wanxiong's group.

At the same time, in the past, Qin Yan's group was led by Qin Yan, but now it has become a dark leader, and the young couple follow behind to discuss prescriptions all day long.

The first recipe is the most important!

Because even if the herbs that are impossible to add to the prescription are removed, the remaining number is still more than a thousand. If you use the way of number series collocation, every possibility is matched, it is simply impossible: the combination of more than 1,000 kinds of medicinal materials itself will reach a crazy astronomical number, and on this basis, it is necessary to divide the main drug and the auxiliary drug, and the main drug and the auxiliary drug have a few flavors and do not know the way, even if you can really test all the pairing of this astronomical number...... Don't forget, the prescription of Chinese medicine is not only about the herbs used, but also the proportion of each herb.

In short, a combination of all will definitely not work.

Not to mention that some medicinal materials are very precious and very rare, it is impossible to have so many medicinal materials to combine them one by one, even if there are inexhaustible medicinal materials?

Experiment with all possible combinations, plus the judgment of the main drug and auxiliary drugs, plus the ratio of the amount, even if Qin Yan doesn't do anything, he won't be able to try all the combinations in a million years.

Therefore, the most reasonable and only feasible way is to find a prescription that is most likely to be close to the real through deep pharmacological knowledge.

On the basis of this prescription, it has been continuously improved through experiments.

In this way, it is required that the first prescription to determine the direction of research must not go the wrong way, otherwise it will be in vain to continue research.

To put it bluntly, the first prescription is very, very important, and it must be absolutely correct in terms of pharmacology, otherwise subsequent research will be a waste of time and a waste of medicinal materials.

"The medicinal effect of the immortal-grade medicinal material phoenix tail cherry is to strengthen the foundation of Peiyuan, and taking it alone can temporarily increase the energy intensity, which has a similar effect to the decoction that increases combat power, and I think it can be used as one of the main medicines." Qin Yan said.

"From martial arts to divine martial arts, to immortal martial arts, and then to divine martial arts, what do you think these prescriptions have changed?" Lou Yuqing thought about it and asked rhetorically.

"This ......"

Qin Yan quickly recalled her words, and said after a while: "Before the Sixth Heaven of Martial Dao, it was only to strengthen the strength of muscle strength, and gradually began to have internal qi, true qi and yuan power, in the final analysis, it was the continuous improvement of the energy level. ”

"That's right!"

Lou Yuqing nodded, and then said: "You said that you missed a little, and one of the biggest differences is that in the back, the spiritual power begins to work, and the effect is getting bigger and bigger." The various special abilities of the Immortal Martial Rank are inseparable from spiritual power, such as imperial weapons, arrays, forging weapons, and so on...... I think that the breakthrough of spiritual power at the Heavenly Martial Rank is probably more important than the improvement of the level of energy itself. ”

"That's right! The so-called primordial gods and divine thoughts are actually spiritual power, so ...... The follow-up decoction recipe should focus on the strengthening of mental power! ”

"Although there are not many medicinal materials to strengthen spiritual power, there are also many of them, but those medicinal materials are temporarily strengthened when taken alone. If you want to have a permanent strengthening effect on mental power, which one is the most suitable? ”

“……”

The little couple both have pharmacological knowledge that ordinary people can't reach, and the one who walked in front heard the conversation between the two from time to time, but for him, it was simply a fog.

Kill!

At this moment, the shouts infused with Yuan Force came from a distance, and the direction was the location of Tu Wanxiong's group.

Did something happen to them?

Qin Yan's thoughts were pulled back to reality, and he didn't dare to hesitate in the slightest, and several people galloped towards Tu Wanxiong's side, but when they saw the situation at the scene, including Qin Yan, they all showed a surprised expression......
