In Yun Yueyao's hands, there were also a large number of pills that were scavenged from the place where the bones were buried in the little gold.

There were pills that could be piled up into a small mountain, and there were all kinds of pills in all periods! She didn't have much of the heart to sort it out before, because she was busy with too many things, and all kinds of things came one after another, causing her to study alchemy and not concentrate on it!

It wasn't until she lived at the top of Lingyun Yan's Infinite Peak that she finally followed the little old man to learn Danshu steadily and in a regular manner!

At that time, she had checked the pills stored in the space, some of them were older, similar to the ones she was refining now, and they were Danyi Feng Dan-style pills.

And the bottles are newer, and they are all mud pills!

As for the reason, Yun Yueyao summed it up at that time that the technique had deteriorated, and one generation was not as good as the next!

Ling Yunyan knew that she had his ancestors teaching Danshu, and when she went out several times, she also bought her a lot of books and jade slips about Danshu, and many miscellaneous books for her to relieve her boredom, which were real miscellaneous books!

While learning from the little old man, she looked at the codex, Danshu books, and jade slips in the space, and in her spare time, she would also look at the Danshu books and jade slips that Ling Yunyan found for her.

Compared with the two, the difference is even greater!

If you talk about the difference between the previous Aura Sealing Pill and the Mud Pill, it may be that the technique has regressed. The difference in grade is not the same!

In the Immortal Spirit Continent, the grade of the elixir was only the sixth order.

Yipindanyao is suitable for taking below the foundation building period;

The second grade of the pill is suitable for taking during the foundation building period;

Sanpindan medicine is suitable for taking in the Jindan period;

Sipindan, suitable for infancy;

Wupindan, suitable for out-of-body period;

Liupindan, suitable for distraction.

Of course, this is only a rough classification, and some special pills are not limited by grade, such as the Cleansing Pill, the Creation Pill, the Longevity Pill, etc.

And the Dan technique that the little old man taught her, the classification of the pill is nine orders!

The seventh-grade to nineth-grade elixir is the pill required from the combined period to the tribulation period. And the ten-grade elixir, also known as the half-step elixir, can only be refined by monks in the late stage of the tribulation.

There is a half-step elixir, and there is naturally a quality of elixir, but such a precious thing is difficult to produce one in ten thousand years. And even if someone refines it, that thing will be too against the sky, and it will be crushed by the heavenly way of liquidation, and the elixir that can withstand the thunder can be completely withheld, at least the little old man has never heard of it.

In addition, each grade of elixir can be divided into low grade, medium grade, upper grade, best grade, and super grade according to its quality.

The best elixir is already rare in the Immortal Spirit Continent, and the super elixir is the perfect level, and in the current world, it can only be found in the cave mansion of the ancient monks.

However, Yun Yueyao can already refine the Super Grade Blood Pill, although it is only a first-grade pill, but the Super Pill is not limited by grade, even if it is taken during the Golden Pill period, it has a certain effect.

In the upper realm, the myelin-washing pill, the spiritual cleansing liquid, the creation pill, the longevity pill, the Peiyuan tonifying pill, the marrow washing casting elixir, etc., these special-purpose pills are all classified as non-pinned pills.

However, the Immortal Spirit Continent is either unheard of a certain elixir, or it is divided into grades according to the rarity of its materials.

When Yun Yueyao was learning Danshu at the top of Wuji Peak, she really didn't get used to this difference in the first two years, but after a long time, she got used to it!

She thought: Just familiarize yourself with the knowledge of the upper realm in advance, and in the future, you will soar, and you will not be black-eyed and cheated everywhere!

Just as her thoughts were flying, several rays of light flew in the distance, and the destination was very clear, pointing directly at her, Yun Yueyao raised her eyebrows, so soon?
