Dan Dao is the essence of Taoist doctrine.

Dan Dao is divided into Outer Dan and Inner Dan.

Wai Dan, that is, a means of improving one's own cultivation with the assistance of various pills. Alchemy alchemists all claim to be their own elixirs, capable of immortality, and such divine sticks have been endless.

Of course, the Wai Dan assistance is very useful, whether it is to practice martial arts and cultivate the truth, or to prolong life. But if you take a big pill, you can live forever and live forever, this kind of thing is too mysterious!

In the world of Xianxia, there may not be no elixir that can last for a hundred years, or even hundreds of years, but ordinary people take it for fear of a miserable death.

Neidan is based on the theory of refining the outer pill as the appearance, combined with the idea of the unity of heaven and man, using the essence of its own internal organs and six internal organs as medicinal materials, intercourse with dragons and tigers, both water and fire, and finally refine its own essence and spirit in one, and achieve a practice method that does not break the surname Jin.

Neidan, also known as Jindan Avenue.

The so-called cultivation of surnames does not cultivate life, and it is difficult for the Yin Soul of Ten Thousand Tribulations to enter the Holy Spirit. This sentence is just right for Yan Li.

In his previous life, he cultivated a hundred years of state of mind, and he was able to prove that he was a primordial god, and his reincarnation was immortal, which was unfathomable. However, in the era of the end of the law, he did not get any method of cultivating his life, and if it weren't for his luck, he would still be standing outside the gate of the Great Dao in the end.

Therefore, in this life, he was fortunate to learn the Dan Dao, and he naturally kept thinking about various possibilities at all times.

Kendo is the basis for crossing the calamity, so it is important.

Dan Dao is the foundation of life cultivation and the most important thing.

As Yan Li said to Guiyun, according to the theory of traditional Chinese medicine, each person's own conditions are different, the symptoms are different, and even the same symptoms have different internal causes. Therefore, there is a saying in traditional Chinese medicine that the same symptoms are different from each other, and different diseases are the same with the same prescription.

That is to say, different patients may need different prescriptions for the same disease, and conversely, different diseases, different patients may use the same prescription.

So, different martial artists, different inheritances, and different martial arts and surnames, all use the same kind of "Qi Nourishing Pill", can they really achieve the best effect?

People from the other world are not fools, so the truth may not be unexpected. The Danfang of the Qi Nourishing Pill has always remained fixed, perhaps for one reason or another.

The biggest possibility is that it has the widest range of application, medicinal materials are relatively easy to find, and it is more suitable for the sale of finished medicines.

Just like the earth's "Liuwei Dihuang Pill", the prescription has not changed for hundreds of years, and the pharmaceutical factory will not adjust the ingredients of the prescription because of the special situation of a patient.

Proprietary medicines only need to be adapted to the public.

Of course, Yan Li could think through this, but he would never use himself to do experiments, let alone gamble with his body and future cultivation.

The same is true for the friends around her, even if they are voluntary, Yan Li will repeatedly consider it, and will never let these people get into danger easily.

Therefore, Yan Li has never mentioned these contents to others so far.

Now, Du Hong has sent it to the door himself!

It's just a chess piece, even if something goes wrong with future cultivation, what can it do? As long as it doesn't affect the things in front of you.

If it weren't for the oath, Du Hong would not have been loyal to Yan Li, and conversely, Yan Li would not have any trust in him, let alone take any responsibility for his future.

Du Hong's pulse, Yan Li has already checked. His inheritance, Yan Li prepared a new compilation for him.

That's right, it's a new one.

According to Yan Li's previous life, and the recent reading of the collection of Bian Que Pavilion and Zhuzen Temple, it has just been edited and sorted into a Taoist inheritance. In addition to improving cultivation, his special surname has other wonderful uses, of course, it is also for the purpose of Yan Li.

What, Du Hong may be reluctant to change the inheritance?

It's too underestimate Master Yan's three-inch incorruptible tongue!

This new prescription is based on the formula of the Qi Nourishing Pill, and is revised according to Du Hong's own condition and the special surname of the new body.

The new Danfang is still based on ginseng, angelica, and ganoderma lucidum three flavors to nourish qi and blood, and adds silver sheep weed and other medicinal materials to reconcile the new medicine surname.

The prescription has changed drastically, and the refining process naturally needs to be adjusted. The application of the various techniques, as well as the time required for each process, requires a detailed calculation.

Most of the calculated parts are done by Yan Li. Guiyun's children are only good at following the rules, and it is really difficult for him to innovate. But the refining of the first furnace of elixir has become Guiyun's task.

Without him, Yan Li didn't have such magical things as "spiritual sense" and "spiritual energy", and there was no way to monitor the changes in the Dan furnace at any time, so he could only let genuine cultivators do it for him.

For the sake of monitoring convenience, Guiyun did not use the Shinto sacrifice method, but used his own cultivation to urge the Dan furnace.

The process of innovation is always tough.

In order to save medicinal materials and also reduce the cultivation load of Guiyun, when trying to refine, only the minimum amount of medicine was put in, that is, six pills.

The surname of the first pot of pills is quite far from the plan. The difference is mainly reflected in the excessive yang fire in the surname of the medicine, Du Hong really eats it, he has to go to the Qinglou Chu Pavilion and ask more than a dozen girls to vent.

The second furnace of elixir is still not as expected, but it is developing in a good direction.

Well, okay. The so-called good direction is not that the side effects of the aphrodisiac surnamed Lie are reduced, but that the adjustment is a little too much.

The third furnace of elixir was adjusted again and finally achieved the expected effect. His medicinal effect, combined with Yan Li's new inheritance, was enough for Du Hong to break through the blood exchange in a short period of time.

If the test is successful on Du Hong, the perfect match between this kind of skill inheritance and pill will also have the value of promotion!

The new elixir was named "Pengyang Dan" by Yan Li.

What's the name of this Dan...... The reason for this is not yet humane.

The most valuable thing in the three alchemy experiments was not refining Peng Yang Dan, but Yan Li's further understanding of the Xuanqi alchemy method of the other world. Every step, every trick, every bit of gestation time gave him a new understanding.

He discovered an extremely critical problem: the efficacy of the elixir refined by the "Immortal Law" had undergone a very drastic change.

This is not nonsense.

In the case of the Qi Nourishing Pill, the dispensing in the Dan prescription is balanced, and the refined pill is also balanced, and there doesn't seem to be any problem. It's just that this prescription has not been refined, and the effect is far less good than that of the pill, and there will even be many side effects.

And the first draft of Peng Yang Dan's prescription is also a very balanced prescription, just like the Qi Pill, which can be directly decocted and taken. But after refining, its side effects are unimaginable. Its medicine is so strong that ordinary people will definitely die if they take it.

The second draft has been revised on the basis of the previous one, and it is still a prescription for the balance of the ratio of the monarch and the minister, but after refining, there are still great side effects.

The success of the third draft was based on the first two failures, and the ratio of medicinal materials in it was adjusted in a compromise manner, and the result was a Dan prescription with almost no balance to speak of.

It's this random prescription that looks like death or injury, and it turns out to be successful!

To paraphrase a famous saying on Earth: after ruling out all impossible outcomes, the final answer is the truth, no matter how unbelievable it is.

Yan Li believes that there should be no problem with the inheritance of the earth's pharmacology for thousands of years, and the pharmacology of the other world has at least a thousand years of inheritance, and there will not be much difference either. Since the results of the two theories are similar, there is only one possibility.

There is something wrong with the process of alchemy.

The magical ritual that was full of smoke and clouds really had its mysteries, and it was not as simple as stimulating the surname of the medicine and filtering the residue of the medicine. The medicinal surnames of many medicinal herbs have changed dramatically in the process, and can even destroy the balance of the original prescriptions.

When she first made alchemy, Yan Li felt that there didn't seem to be much spiritual energy intervention in the whole process, except for the final "spiritual infusion", and the magic seemed to be mysterious, but in fact, it was just a physical and chemical process such as water bath temperature control heating, stratified filtration, centrifugal force separation, distillation, and precipitation. If you study the refining process thoroughly, you can use other means instead.

But now it seems, it's not that simple. In the process of alchemy, some kind of transformation has obviously taken place in the medicinal materials, so they can have effects that are difficult to achieve by ordinary means!

Finding the mistake, Yan Li was not only not frustrated, but faintly excited.

With his state of mind, success or failure has long been out of sight. His gaze will look straight ahead:

The refining of the outer pill will undergo the transformation of the mystical and mysterious, so can the cultivation of the inner pill also be deduced by analogy?

The gate of the Otherworldly Dan Dao has opened a gap.

He seemed to see a little footprint of the Great Dao in the vast immortal sea.

This feeling is clear and bright, not at all like in his previous life, when he walked alone in the reckless red dust, only proving his own heart.

At the same time, Yan Li also felt for the first time that her cultivation should be improved faster - letting an eleven or twelve-year-old child be a coolie was really a bit of a black heart.

Of course, Yan Li also understands that if you want to hurry, you can't reach it. The improvement of cultivation cannot be achieved overnight, and can only be considered in the long run. On the contrary, starting from the study of Dandao, there is a lot to be done.

The new pill, relying only on the adjustment of the prescription and the inspection of the pill, can only make a rough inference, and the final effect still needs to be tested in practice.

Du Hong, Du Hong, you have to behave well tomorrow. Otherwise, if you want to give away the inheritance and elixir of this master, you will have to spend a lot more words.

The small situation of the Hengjiang Gang is nothing, if you dare to delay this master's pill experiment, hehehe......

――......――

Early the next morning, Buchen came to the door.

Buchen is a sincere person.

He was instructed by Zheng Meng, and he was still grateful to Dade. What's more, Yan Li's words not only made him break through the exchange of blood, but also made him make great progress in martial arts, and he has been in the hall since then?

Since yesterday, he has been saluting Yan Li's disciples. In addition to the sprinkling sweep in the gambling contract, he naturally regards the matter of wind and fire forging as his own business.

In his mind, Master Yan could not take his recklessness in his eyes, but he received such a great favor, and he would be reciprocated.

The joy of the housewarming is not too big, but the neighbors, relatives and friends compete to congratulate them, and the three-day flowing water banquet is still needed. Wind and fire forging up and down, but there are two or three big cats and kittens, and Master Yan plays the role of a young master again, he doesn't care about things at all, he has to deal with many trivial things, and his manpower is naturally stretched.

At this time, Buchen naturally stepped forward, took a dozen brothers from the Dongsha Gang, and took all the troubles.

Yesterday, at the banquet, Duan Yan, the young master, drilled under the table early, and Duan Heihu, the big boss, was later carried back to the room full of nonsense, but Buchen was busy until the first shift and the banquet was dispersed.

Today, he still came to the door early in the morning and brought a congratulatory gift from the helmsman Fu Jingshui.

Fu Jingshui put down his help to Buchen and led the brothers to come to Fenghuo Training, not only did not complain at all, but praised him greatly: Good men have clear grievances and grievances, and they should be!

Immediately, he made up a generous gift, and said angrily: "Why didn't you let people inform me yesterday? Wouldn't it make friends in the rivers and lakes laugh at me Fu Jingshui is stingy? I'm not Zou Tong!"

Buchen led the brothers, carried the congratulatory gifts, and happily walked into the wind and fire forging, who knew that when he looked up, he met Du Hong.

He couldn't help but secretly say that when he encountered this guy, it was inevitable that he would talk about it. Bu is not afraid of him, but how can he add to the happy event of wind and fire forging?

Who knows, Du Hong not only did not have a yin and yang weirdness, but his face was full of joy, and he politely hugged his fist in the face of Bu Chen, and said with a hearty smile: "Brother Bu came so early! The incident two days ago was that Du was wrong, and I still look at Brother Bu Haihan!"

Buchen and his little friends were instantly stunned: What kind of trouble is this?
