Yan Bugui and Bai Juan have been hurrying on this grassland, although they have not done their best for the sake of safety. But its speed is definitely not slower than the chariot of the secular world that travels hundreds of miles a day.

It is said that there is an idiom 'walking around the flowers', although people are refreshed and comfortable on the horse, and the momentum and pomp are also spectacular, but they can't pay attention to many details at all, so the harvest is limited. It's just because the two of them don't walk fast, otherwise Bai Juan wouldn't have found the beautiful grass. This is not Bai Juan stood in front of a small grass and exclaimed: "What a beautiful little grass!" Yan Bugui stopped to watch, but saw that this grass was more than a foot high, and the shape was not much different from ordinary grass, but the key was that this grass was blue all over, and even emitted a faint fluorescence.

Although Yan Bugui couldn't see what the name of this grass was, it was certain that it must be a precious medicinal material, so he was distracted and went into the jade pendant space to consult the master Sang Yu. After all, there is a specialization in the art industry! Now I really found the right person, Sang Yu actually said that this grass is a precious herb, called "Yin Spirit Grass". The "Yin Spirit Grass" grass blades can be used in the refining process of some top-grade pills, which can ensure that at least 50% of the baked pills are top-grade pills.

In other words, this "Yin Spirit Grass" is an auxiliary pill for refining some top-grade pills. As for this auxiliary elixir, it can only be a water-attribute elixir. But this auxiliary function is not unpowerful. After all, for an alchemist, it is already a good alchemist to be able to ensure a certain success rate of Dan. And if it can still be guaranteed that the elixir is of the best quality, it will be simply an alchemy grandmaster! As for the fact that more than 50% of it is the best elixir, even if it is an alchemy master, it can only be met by chance and cannot be forced.

Of course, the "Yin Spirit Grass" must have a certain age, and it is said that it must be more than a hundred years old to improve the quality of the elixir. However, the growth of "Yin Spirit Grass" is exactly like the growth cycle of ordinary grass, which sprouts every spring and begins to wither after autumn.

Sang Yu explained that the year of the "Yin Spirit Grass" grass leaves is not based on the leaves, because the leaves are all sprouted and grown in the same year, and the year of the "Yin Spirit Grass" grass leaves is judged to come from the rhizome. That is to say, how many years the rhizome has, the leaves that grow have the effect of how many years. The age of the leaf can also be inferred from the texture of the leaf.

Don't say that I don't know the way, and I heard what Sang Yu said. It seems that in the future, we will need to read more information and understand some common sense. Then Sang Yu also gave Yan Bugui those books about the introduction of the pills with the attributes of the five elements and the auxiliary medicinal materials that could improve the quality. Of course, Yan Bugui also learned after this that there was also the 'Golden Scale Fruit' to improve the quality of the metallic elixir, the 'Tianling Fruit' to improve the quality of the wood attribute elixir, the hundred-year-old 'Yin Spirit Grass' to improve the quality of the water attribute elixir, the 'Longlin Fruit' to improve the quality of the fire attribute elixir, and the 'Thousand Potato' is the wild sweet potato that is the vine knot of the thousand-year-old wild sweet potato, but it can improve the quality of the soil attribute elixir......

Later, Sang Yu also told Yan Bugui about the transplanting method of the 'Yin Spirit Grass', and Yan Bugui hurriedly went out of the space and brought the 'Yin Spirit Grass' with a large piece of soil into the 'Sang Green' space in the mysterious brocade box, and planted it in the medicine garden. For these things that can improve the attributes of the Five Elements Pill, Yan Bugui wants to raise them very much. After all, he already has two of them, no, strictly speaking, it should be three. Because the 'Thousand Potatoes' are only a little more vintage, as long as you find an opportunity to dig up some wild sweet potato vines and plant them in the 'Sanglu' Medicine Garden, you can wait for three years to be harvested. As for the other two, Yan can only be full of longing if he doesn't return it.

Yan Bugui knew that even if he had the mysterious brocade box as a cover, Bai Juan would not think of anything when he thought of the 'Heavenly Spirit Fruit' last time. Although Yan Bugui also knew that she was a good girl through her contact with Bai Juan over the years, Yan Bugui also believed that she would keep it a secret for herself. But Yan Bugui would never take the initiative to say anything to her, if nothing else, Shi Gong's top-secret order of Ming Yuetian had to do so.

But Bai Juan had an explanation from her master in front of the Ten Thousand Beasts Mountain, so she wouldn't be curious to ask. If there is doubt, there will be a doubt, she believes that she should know that the Tao will eventually be done. So even if Yan didn't return to dig the 'Yin Spirit Grass', she didn't ask anything, and even went to the neighborhood to pretend to find out if there was such a 'Yin Spirit Grass'. Yan Bugui sincerely expressed her gratitude to Bai Juan for this intellect and understanding!

But that's what happened after that. Because not long after digging the 'Yin Spirit Grass' and leaving, the careful Bai Juan found that they had returned to the place where they had dug the 'Yin Spirit Grass'. In fact, Yan Bugui is the most clear about this pit where he dug the 'Yin Spirit Grass', after all, he dug it with his own hands, so he was very impressed. This is definitely the pit he dug before, absolutely!

But the key is that they are all moving in the direction of the slope of this grassland, and this slope has absolutely no place to go up or down, which means that the two of them have been moving in a straight line. But why did they return to the same place? They are all immortal cultivators, and there will never be ghosts hitting the wall to be stumped! Both of them know that this is because of the formation. But the specifics are not clear. Helpless!

The two of them were puzzled, and then Yan Bugui had no choice but to dig out the "Wang Yinjia Formation Collection and Experience" to check it carefully, and finally knew that this formation was called 'God Wall', which means that even if the gods are trapped in it, they must be surrounded.

As for the 'God Wall' formation, in fact, it will only be opened if a certain formation point is moved. And the easiest way to crack this formation is to restore the original movement. If it is to move a stone or something, it can be restored, but now Yan Bugui has dug up the 'Yin Spirit Grass' and wants to say that it will be restored, it is simply a joke. What's more, Yan Bugui really wanted this 'Yin Spirit Grass', so he didn't plan to restore this formation at all.

Yan Bugui began to think about the way to crack this formation. As for this 'Divine Wall', even the "Wang Yinjia Formation Collection and Experience" only mentioned it simply, and there were no other annotations.

Yan doesn't return to think and think, how can he understand it. Come to think of it, other formation mages may be able to lay out such a formation after studying all their lives, and you are not so professional to be able to crack it in a short time, isn't that a big joke in the world?

Yan Bugui figured out this layer, and he no longer thought about cracking the formation. Instead think about something else. Suddenly, Yan Bugui's mind flashed: Why is the eye of this formation in the place of this 'Yin Spirit Grass'? Could it be related to the 'Yin Spirit Grass'? And as far as the layout of this formation is concerned, there is absolutely no malicious intent, otherwise it will be mixed with other formations such as attacking the deceptive formation.

Thinking about it like this, there should be some hints! Yan Bugui went to the pit to look for it again, and actually found a piece of jade slip for him. I think it may be a ** or Danfang record, or it is related to this formation.

Yan Bugui put this jade slip on his forehead and began to read it with mental power.
