When Ning Yujun introduced a kind of pill called 'Advance Dan', Yan Bugui not only inquired curiously. But after listening to Ning Yujun's introduction, he realized that this so-called 'promotion pill' was not used for promotion. Rather, this pill has the ability to directly allow cultivators below the Yuan Infant to directly advance to the upper level of cultivation without any promotion process in an instant after taking it, even if the Yuan Infant cultivator cannot advance after taking this pill, he can also directly improve his cultivation to one to two percent, and it is said that his lifespan will increase by at least a thousand years.

If it is simply analyzed like this, then this Dan is really against the sky to the end. Its value is simply immeasurable! But after Yan Bugui asked for details, he realized that this kind of elixir can only be taken once in a person's life, otherwise taking it again will result in an explosion of spiritual energy. And after taking this elixir, it will be more difficult every time you advance on the road to cultivating immortals in the future.

Yan Bugui thought, now if you pursue promotion to fusion, then the difficulty will be doubled when you get married, and if you want to advance to Yuanying again in the future, the difficulty coefficient will become 4 times. By analogy, the path of cultivating immortals after taking the 'Advancement Pill' is bound to stop soon. But if the 'Promotion Pill' is used to save lives on a specific occasion, then it is not a clever means. If you take the 'Promotion Pill' to advance to the first level, and you want to save your life in that situation, although it will increase the difficulty of the promotion in the future, it is better to save your life than to sacrifice heroically on the spot!

But in fact, there can be a situation where the 'promotion pill' is very valuable, that is, the life span of the monks before the knot will not exceed a thousand years, even if the life span of the valley, enlightenment, and fusion below the knot pill is increased by 200 years, it is quite good, and if the knot pill can be as long as 2000 years. If it is the kind of person who has no hope of advancing to the next level, if there is this 'Promotion Pill' to take, it is better than dying directly. Therefore, this 'promotion pill' can also be called 'longevity pill'!

After all, even if the difficulty of promotion will be doubled in the future, but if you have an extra thousand or a hundred years of life, maybe you will have a chance to take another step on the road of cultivating immortals? But even if the road of cultivating immortals stops, how can it be said that the pursuit of cultivating immortals is longevity, so it is better to have more than a thousand or a hundred years of enjoyment, even if it is not enjoyment, you can also do a lot of things for your descendants. Therefore, no matter who it is, this 'promotion pill' can be said to be a treasure.

And this promotion pill actually has the effect of saving lives and longevity, even if the side effects are very large, then its value must be far above the 'Dingyan Pill'.

Therefore, Yan Bugui still wanted to know the value of the Dan prescription of Lu Dao, and asked Ning Yujun to ask for 200 demon pills, instead of asking for some medicinal materials needed for the Dan prescription as he said before, and Ning Yujun said that it was still in the case of half selling and half giving away. As for the root cause of the delivery, it is that there are actually more than 200 kinds of medicinal materials needed for this 'Promotion Pill', and they are basically thousand-year-old medicinal materials, which is also secondary, and the most important thing is that there are several medicinal materials that have become extinct in the cultivation realm.

Thinking about it, in this pill, there are too many medicinal materials that the Ning family can't raise, and even if they ask for one or two, it is impossible to refine the pill, so it is better to directly exchange it for the demon pill or the 'promotion pill'.

To say that the 'Heavenly Spirit Fruit' is a rare thing in the world, it is only a legendary thing, although it is rare, but after all, it still exists, but to say that the extinct one is not really extinct, but it must be more difficult to find than the legend, and this Danfang actually has several extinct medicinal materials. Therefore, it is strange to say that this pill can be refined into pills!

Yan Bugui analyzed, but Ning Yujun said: "This 'Advance Pill' pill recipe is indeed too tricky! But the Immortal Cultivation Realm is so big, maybe there are sects that can gather these medicinal materials. And although our Ning family has this pill, even if the cultivation realm can raise all the medicinal materials now, we don't have the financial resources to collect it! But I still don't want the wisdom of the ancestors to be ruined, so I only sell and half give away this pill. Of course, if any sect can raise the medicinal materials needed for this pill in the future, at least eight or sixty-four 'Advance Pills' can be produced in one furnace, and I will be content with only two 'Advance Pills'!"

Speaking of this, Ning Yujun's eyes were confused. Then after a pause, there was a sigh, and after a pause, he still said that those important medicinal materials were related to Yan Bugui, and as for those medicinal materials that had become extinct, he told Yan Bugui word for word, and also talked in detail about the properties of these medicinal materials and some relevant information such as collection, dressing, preservation, etc.

Although Yan Bugui hadn't seen this pill recipe, to be honest, he had learned a lot of things from Ning Yujun that he had never heard of before! In addition, no matter whether or not he was finally able to refine the 'Advancement Pill' in the cultivation realm in the future, Ning Yujun's dedication was also worthy of admiration and respect!

Then Ning Yujun went on to introduce those pills, but Yan Bugui only cared about a pill called 'Immortal Spirit Pill', this pill recipe should only be useful to beginner immortal cultivators, that is, after taking this pill, it has the effect of a medicinal bath of seven or eighty percent. Later, Ning Yujun also said that the medicinal materials needed for this 'fairy elixir', although Yan Bugui did not have a list of medicinal materials for medicinal baths, according to Ning Yujun, the medicinal materials required for this Dan prescription were basically the same as those used in medicinal baths.

However, the peculiarity of this 'elixir' lies in the need for a medicinal herb called 'Rhodiola', and it also needs to be at least thirty years old. And the older the Rhodiola Rosea, the closer its effect is to that of a medicinal bath.

Rhodiola rosea, also known as "Soroma Bao", is a perennial herbaceous plant that generally has a harvest cycle of four years and is about three to seven inches tall. The roots are stout, conical, fleshy, brownish-yellow, and the root neck has many fibrous roots. The rhizome is short, thick, cylindrical, and has scaly leaves arranged in a mostly shingle-like pattern. Old stems sometimes persist, the stems are unbranched and leafy. Several flower stems are drawn from the axils of the leaves at the top of the stem, and the upper and lower parts of the flower stems have fleshy leaves, the leaves are oval, the edges are serrate, the apex is sharp, the base is wedge-shaped, and almost sessile. The inflorescences are apical and the flowers are red. It grows in plateaus, alpine and pollution-free areas. Due to the harsh growth environment of Rhodiola rosea on the plateau, it has strong vitality and special adaptability. Collected in July and August.

Since it is a four-year cycle, that is, there may be cases where the old stems sometimes remain, but the years that take at least 30 years are definitely more difficult to find than the thousand-year-old medicinal materials. But Yan Bugui doesn't care about this, after all, the 'mulberry green' space planting should still be able to meet this requirement.

Then Yan Bugui consulted Ning Yujun, and Ning Yujun's request was very simple, that is, as long as one plant of Rhodiola met the requirements of Danfang. But Ning Yujun thought for a while and said, "It is indeed too difficult for Rhodiola to reach the Thirty Year Age, and it is indeed a little embarrassing to take out a Rhodiola rosea to trade the Pill to refine this pill." Otherwise, if you buy this pill, you can just give me 2 pills when the pill comes out. You can rest assured, it is recorded that a furnace of pills can produce 7 or 8 pills. But if you are reluctant, then this pill will be a bit expensive and cost 150 demon pills. ”

"150 Demon Pill?" Yan Bugui asked in surprise. Thinking about it, the 'Dingyan Dan' Dan Fang is only worth 80 Demon Pills, and this 'Immortal Spirit Pill' Dan Fang has directly doubled. But even if this 'fairy elixir' is good, its value will definitely not be double the value of the 'Dingyan Pill'!

As soon as Ning Yujun heard Yan Bugui's question, he said again: "With all due respect, brother, you probably haven't experienced the Danfang transaction, right?" The value of the Danfang lies mainly in the value of the pill, followed by the difficulty of collecting medicinal materials and the size of the amount, and the most important thing is the relationship between the quantity of the pills and the amount of medicinal materials put in. The comprehensive evaluation of the 'Immortal Spirit Pill' Dan Fang is definitely worth it even if it is 150 Demon Pills!"

Yan Bugui thought about it and thought that it was too, after all, even if the 'Promotion Pill' was half sold and half given, it would cost 200 Demon Pills. It's just that I didn't care about the price at that time, but I subconsciously felt that I couldn't afford to buy it, so I didn't care about the price carefully.

So Yan Bugui thought that he now had 5 demon pills and 10 spirit stones, no matter how he said it, it was not enough to pay this account, and he had to find his master in the future! Then he wanted Bai Juan to go back to his master to ask for spirit stones, but he stretched out his hand to Bai Juan next to him and stopped: "Senior brother, I just have thirty lower-grade spirit stones given by the master here, so I don't need to run again." ”

It seems that Bai Juan is buying it for the sect on behalf of the head of the sect, so Yan Bugui doesn't have to worry about it anymore. But when Yan Bugui took the thirty spirit stones from Bai Juan and wanted to hand them over to Ning Yujun, he stopped Ning Yujun again.

Yan Bugui secretly said: Could it be that this kid has changed his hexagram?

"Brother, don't be busy trading just yet. I also have to add one thing, that is, the pill that you trade with our Ning family, you can only use it to refine the pill yourself, and you can no longer trade it with others, and you can no longer show the pill to anyone other than yourself. My purpose in doing this is simple: to protect the rights of our ancestors. Of course, if your juniors still want to have this Danfang, our Ning family can give a 50% discount in the future. If you agree to this one, it's not too late to make a deal. ”

Yan Bu came to think of it, the Danfang developed by countless generations of ancestors was bought for himself so cheaply, if he changed hands again, it would not be a big profit. Thinking of this layer, he did not hesitate to make a deal with Ning Yujun.

Originally, this transaction was wanted to be carried out by Bai Juan, but Yan Bugui thought that it was better to handle the matter about medicinal materials by himself. Otherwise, if the secret is leaked later, it will be a big problem. Besides, looking at Bai Juan's situation, she was also full of trust in herself, so Yan Bugui swore in front of Ning Yujun that she would keep the secret of the Danfang, and the content of the oath was nothing more than saying that if Yan Bugui leaked the 'Immortal Spirit Pill' Danfang to others, he would stop cultivating forever and affect future generations. Then there is the transaction, and there is no push to take over the Dan side by himself.
