Among the disciples who entered the valley in the same period, Lin Xuan's current strength can already rank among the top three, and in the late stage of agility, even in a sect like Piaoyun Valley, he can be regarded as an elite disciple, but Lin Xuan is not satisfied, this retreat has not yet ended.

First, there are more than 100 pills of myelin-washing pills in his hand, which can support more than ten days of cultivation, and second, although he has successfully passed the level, he has only just entered the threshold of the fifth layer, and the realm needs to be consolidated and continue to retreat.

Lin Xuan will not be complacent just because he has achieved a little, on the contrary, every success makes his goals more ambitious and has new requirements for himself.

Ling Yun Jue's movement has become more and more proficient, and he can feel that his spiritual power is constantly increasing every day.

In addition to cultivation, the volume of the Star Sea in the body has doubled, and Lin Xuan has encountered a bottleneck in the original purification of the Zhongpin Dan, no matter how he practices and how hard he works, he only has a success rate of twenty percent, which has nothing to do with proficiency, it is purely that the use of the Blue Star Sea has encountered a bottleneck.

And now, after entering the late stage of agility, after the volume of Xinghai increased, this bottleneck automatically disappeared, Lin Xuan tried it, and the success rate of the middle pindan rose to more than thirty percent, and the purification of the lower pindan was even more every three, and failed at most once.

For Xia Pindan, Lin Xuan is no longer very eye-catching, so although the success rate has increased, Lin Xuan doesn't care, but Zhongpindan is different, this trip to Lingyunmen not only allowed Lin Xuan to buy the items he needed, but also understood the market of various treasures in the cultivation realm.

Although the Cleansing Pill is the lowest grade and the most common pill, it is still extremely rare.

Not to mention that Zhongpindan is still of great help to improve one's strength, and the success rate is high, and the proportion of Zhongpindan can be greater among the pills taken every day.

In the past, because of the lack of Zhongpindan, there was only one pill of Zhongpindan, but now it has increased to two or even three.

Driven by the powerful medicinal effect, Lin Xuan's progress was rapid and fast, and after more than ten days, he switched out of the house, at this time, Lin Xuan, although he was still far away from the sixth layer, but the fifth layer realm was already very stable, and even the temperament of the whole person was a little different.

However, Lin Xuan's face did not have much joy, but frowned, the improvement of strength is a good thing, but with the improvement of cultivation, it is becoming more and more difficult to hide.

I know my own situation, although few people come to the Waste Dan Room, but I sometimes need to walk around the sect, and if an elder sees that he is cultivating, it will be miserable.

There is no other reason, he is an ordinary person without a spiritual root, less than a year ago, he was still struggling in the first layer of the spirit period, and a few months have passed in a blink of an eye, and he has actually entered the late stage, so a fool will not doubt it.

If they get to the bottom of it and discover the secret of the Blue Star Sea......

Lin Xuan shook his head, although this possibility is very small, even if the strength is far higher than his own cultivator, it is difficult to detect the situation in other people's dantian, but he is not afraid of ten thousand, he is afraid of just in case, everything needs to be prepared for a rainy day.

What's more, as for how his cultivation could improve by leaps and bounds in a year, Lin Xuan really couldn't think of a suitable excuse.

Is there a way to hide your strength so that others can't see your cultivation?

Lin Xuan frowned and thought about it, this problem could not be consulted by the elders, he could only check the information and solve it by himself.

Lin Xuan came to the Library Pavilion, only the first floor was open to low-level disciples, there were no exercises here, but there were many miscellaneous studies, Lin Xuan spent a whole day, and finally found the answer he wanted.

There is the following record in the "Baicaolu":

Red silk grass, a hundred years old, can refine elixirs such as the Cleansing Pill, and there is also the miraculous effect of hidden cultivation after taking it.

Lin Xuan was overjoyed in his heart, and hurriedly read it carefully, and after a while, he closed the book, but the expression on his face was a little uncertain.

Red silk grass, placed in the world, is a very rare spiritual grass, but it is very common in the cultivation world, refining the marrow washing pill, this kind of medicinal material will be used, there is a special medicine garden in the sect, it stands to reason that it is easy to find.

According to the records in this book, the red silk grass is also divided into grades, the ordinary one is used to refine the marrow washing pill, the middle grade is used to refine the Zhuji Dan, and the best one is used to refine the Huiyuan Dan taken by the monks in the Ning Dan period.

What are you kidding, the materials for the pill taken during the Ning Dan period, Lin Xuan's eyes widened, you can imagine how precious it is, it is impossible for him to get it at all.

"Baicaolu" also writes very clearly, only one of the 10,000 red silk grass plants can appear to be of the highest grade.

Closing the book, Lin Xuan walked out of the library pavilion, although he was lost in his heart, he still had an indifferent expression on his face, in an unnoticed corner, he stood for a while, silent for a moment, and still did not go back to the waste pill room, but walked like a medicine garden.

Half an hour later, Lin Xuan came out of the medicine garden, with an extra bamboo basket in his hand, which was filled with a basket of red silk grass, which he exchanged with the other party with a low-grade marrow washing pill, fortunately, the steward of the medicine garden did not know him, and after seeing Lin Xuan's cultivation of the fifth layer, he behaved very politely.

The reason why Lin Xuan still got so many red silk herbs was because he suddenly had an idea, since he could purify the pill, could the medicinal herbs also be possible?

Lin Xuan wasn't too sure, but he always had to try to find out the results of the Dao, if he could purify the ordinary red silk grass into a top-grade one, wouldn't this hidden cultivation problem be solved?

Back in the waste pill room, Lin Xuan closed the door of the living room and took out a red silk grass from the bamboo basket, which was a herb about twenty years old, exuding a faint medicinal fragrance, and because it had just been unearthed, it was still very fresh.

Red Ayacao is a relatively special medicinal material in the cultivation realm, different grades can be refined into different pills, and the lower grade red Ayacao can only be regarded as ordinary medicinal materials, and the middle grade is more cherished, as for the top grade, it is the great master of the Ning Dan period who will also snatch it, which shows how precious it is.

And the only one that can hide the cultivation is the top-grade red silk grass, Lin Xuan is going to give it a try now, in addition to the finished elixir, whether the blue light spot is also effective for fresh medicinal materials.
