After all, Sang Yu did not disappoint Yan Bugui! In the last twelve days or so, Sang Yu first took advantage of the research of the Dan Fang to refine two more furnaces of the 'Explosive Qi Pill', but these two furnaces only had four pills. However, it has also practiced a furnace of 'Huiling Pills', four.

The so-called 'Huiling Pill' is the effect of converging aura. Its principle comes from a certain Huiling Great Array, which is actually to gather the spiritual energy around the Great Array into the Great Array through the guiding effect of the formation.

And the peculiarity of this 'Huiling Pill' is that it is just a collection of spiritual energy into the human body of the person. In other words, the human body is used as a great array of spirits, guiding the aura around the body of the person to gather into the body of the person.

As for the effect of gathering aura, it also varies from person to person, and it is said that some people can increase the intensity of aura gathering by five or six percent.

To put it bluntly, the absorption of aura is a matter of quantity, if you can't even guarantee this amount, how can you get a qualitative promotion. Therefore, every person is trying to absorb the aura from the outside world into their body as low as possible.

But with this concentration of aura, it's not like you can absorb as much as you want. One depends on the body's ability to accommodate it, and the absorption capacity, and the most important thing is the absorption and transformation ability.

For the cultivation realm, although the concentration of aura is much stronger than that of the secular realm, it still can't meet the needs of the people. Therefore, for the vast majority of people, the absorption capacity of the aura is not a problem, except for those who can not be promoted after reaching the cultivation cap, the most common situation is that the capacity of the body's body is not a problem, and it is not a problem to absorb and transform.

Since there is no problem with all three, where does the problem arise?

It turned out that there was not so much aura for the people to absorb. To put it bluntly, in fact, the richness of the aura is not enough, and each person has its maximum ability to accommodate the aura due to its own root bone limitations, and also has its own absorption speed, and there is generally no problem with the transformation of the absorbed aura.

Therefore, if you want to advance quickly, those with a background generally take some pills or something. In fact, this is a disguised change in physique, or to increase the absorption rate of aura, or even to directly provide aura.

The 'Explosive Qi Pill' is to directly provide the person with aura, and it is also the kind of aura that can be quickly transformed immediately, which is the most fundamental reason why it can make the user cultivate or even directly increase by 30% in a stick of incense.

Although the 'Hui Ling Pill' does not directly provide the aura that can be transformed into one's own cultivation like the 'Explosive Qi Pill', it can allow the person to absorb, accommodate, and even transform the aura between heaven and earth with different amplitudes. It is said that the 'Hui Ling Pill' can even increase the absorption of spiritual energy by up to about 2 to 30% within a year or so after taking it.

Compared with the 'Explosive Qi Pill' and the 'Huiling Pill', both have their own merits. Although the former is only a stick of incense, it can be improved to three percent in a short period of time, which is needless to say that it is a life-saving straw and an amulet.

And although the 'Hui Ling Pill' cannot allow the person to cultivate and improve in a short period of time, but the uninterrupted time of a year will continue to increase your absorption of spiritual energy by two or three percent, isn't this the best elixir for cultivating immortals? There is no need to doubt that this is a peerless elixir for cultivation! It is the best choice when the bottleneck is broken!

Yan Bugui couldn't tell who was better for the two pills that Sang Yugang had refined, but whether it was the 'Explosive Qi Pill' or the 'Huiling Pill', they were not ordinary, and they should cause a sensation when they were auctioned. But Yan doesn't return to care about those problems.

Yan Bugui can still take the 'Explosive Qi Pill', but for the 'Huiling Pill', because there is already a 'Sanglu' space, it is also a chicken rib to ask for this thing.

So after thirty days, Yan Bugui came out of the alchemy room, and when he saw the shopkeeper Li again, Yan Bugui didn't have to keep two for himself for these two pills at all, but handed them all over to the shopkeeper Li.

Shopkeeper Li saw that there were thirteen 'Explosive Qi Pills' and four 'Huiling Pills', and the hand that received the pill trembled violently a few times, as for the eyes, it could be said that he was shocked.

Of course, Shopkeeper Li didn't think that Yan Bugui had this alchemy ability, after all, it was impossible for a person to be able to refine a pill like Xu Dan within a month from getting the pill. Of course, if it were a few super-level alchemy masters, it would be a different matter.

In fact, it is true that Yan Bugui does not have this alchemy ability, but the alchemy is only Sang Yu!

Shopkeeper Li thought of one of them, but he couldn't think of them at all. But Shopkeeper Li is a smart person, so he won't care about these, no matter how you Yan Bugui found three or five to alchemy, but there is only one furnace, how can you say that the alchemy is also at the level of a super-level grandmaster.

And after Shopkeeper Li looked at those pills, he deduced a rough idea from the difference between the thirteen 'Explosive Pills'. After all, among these pills, five 'Explosive Qi Pills' were two percent higher in quality than the other eight 'Explosive Qi Pills'.

And those four 'Huiling Pills' and those eight ordinary 'Explosive Qi Pills', although they can't compare to the quality of those five 'Explosive Qi Pills', they are definitely not what ordinary alchemists can refine! Could it be that he is from a certain alchemy sect......

Yan Bugui and Shopkeeper Li had a detailed divine exchange on the specific matters of these transactions......

Then Yan Bugui came to a square behind 'Long Yuanxiang' with Shopkeeper Li......

It is said to be a square, but the entrance and exit of this square is only a passage through 'Long Yuanxiang'.

Of course, Yan didn't return, and someone else brought it in directly from a fork in the passage. Now, Yan Bugui is sitting in a row of boxes at the front of the square. It's a box, it's a box, but it's gorgeously decorated. However, these are all superficial things, but in essence, they are blessed with some formations, and even those cultivators can't see them with their divine sense.

After Yan Bugui sat down, someone handed over the fragrant tea, so there was no need to say more. But Yan Bugui saw that the shopkeeper Li and a round-faced, big-bellied middle-aged literati-looking man on the stage communicated for a while, and the people below the square were not tens of thousands, but there must be eight thousand.

Then I saw Shopkeeper Li stretch out his right hand, waved his hand lightly at those people, and said, "Welcome all colleagues to come to the 'Red Moon Alliance'! Today, our 'Long Yuanxiang' will preside over this auction, and it will last for about 12 hours. The next day after the auction ends, the passage to the auction hall will open. There will be a lot of surprises during this period, and how much you can gain depends on your vision and means. I won't say much about other kind words here. The rest will be directly handed over to our professional bidder Li Shengnan. Here's wishing you all the best of luck!"
