There is no other reason, in the cultivation world, alchemy is a highly skilled work, even if it is an experienced master, the success rate is not high, usually refining three furnaces of pills, there will be a furnace scrapped, and because the content of impurities is too high, after taking it, not only is it not beneficial to cultivation, but it will damage the body, and it is usually only painful to throw away.

There are already few spiritual herbs of all kinds, coupled with the difficulty of refining, and the success rate is not high, which makes the elixir even rarer.

This made the cultivators a headache, especially a small sect like Drifting Cloud Valley, the alchemist skills were limited, and the failure rate would be higher, I heard that it was only fifty percent, so even the Purifying Pill, the most common and lowest-level pill in the cultivation realm, could only give disciples a small amount of two pills per month.

The rarity of the elixir, the wolf and the lack of flesh are the factors that restrict the improvement of the cultivator's skill, even if the spiritual root is excellent and the diligent cultivator is also inseparable from the aid of the elixir.

However, this is a huge opportunity for Lin Xuan.

Because these mysterious points of light in the body can defy the sky and turn waste into treasure......

Taking Piaoyun Valley as an example, there are about 300 disciples in the Spirit Movement Period, and each person has two marrow cleansing pills per month, a total of more than 600 pills, but due to the failure of refining, the waste pills generated will be about this number.

Waste pills are harmful and useless, they are pure garbage, this is the understanding formed in the cultivation realm for tens of thousands of years, although the waste pills that have failed to be refined, although they are not discarded at will, but the management is also very chaotic, and no one pays attention to them, so Lin Xuan started the idea of these waste pills.

There are six hundred waste pills per month, if you can get your hands on them, and then use the blue light dots to turn them into useful elixirs......

In this way, you can use the pill as a sugar pill, and even if you don't have a spiritual root, your own cultivation speed will be faster than that of your peers.

The prospect was very good, but Lin Xuan was not hot-headed, even at this time, he remained very sober and planned for what he should do next.

The first is to explore the reason, how a waste pill became a precious elixir, the reason must be clear, what conditions are needed, how to control the blue light spot, and understand the process, otherwise the wonderful idea just now will be a mirror, you can see it, you can't touch it, in short, the use of blue light points needs to be mastered.

After determining the target, Lin Xuan put the elixir in front of him and observed it carefully.

The color and fragrance are not wrong, except for the last time when he was troubled by Elder Ma, Lin Xuan had also taken the lower grade marrow washing pill before, so he would never admit his mistake.

In order to be insured, he also took out a real pill from the storage bracelet, this pill was collected from Zhou Yan, and the two were compared.

Compared with the authentic Pulp Cleansing Pill, the only difference was that the volume of this pill transformed from the Waste Pill was slightly smaller, and there was a pile of black paste powder next to it, exuding an unpleasant smell, which attracted Lin Xuan's attention.

Impurity?

Of course, Lin Xuan would not let go of such an important detail, and he recognized its origin very accurately, the reason why the elixir refined with rare medicinal materials as raw materials would be scrapped was because the waste pill contained too many impurities.

In other words, there are not many essences in the Waste Pill, but the impurity content is too high, and it is affected, so it is useless for cultivation.

If the impurities in the waste pill can be removed, and the essence part is purified, the waste pill can also be turned into an elixir, but this is only theoretical, it is easy to say, but the actual operation is more difficult than ascending to the sky, for tens of thousands of years, the various sects, scattered cultivation masters do not know how many attempts, but there is no successful example.

After countless failures, the cultivators also gave up, and could only endure the pain to discard the waste pill, and for tens of thousands of years, the cultivation realm has cultivated to the realization that the impurities in the waste pill cannot be removed.

But in front of me, the pile of black powder is obviously impurities!

Lin Xuan pondered for a moment and began to make bold assumptions, could it be that the function of the blue star sea in his body was to purify, remove impurities, and concentrate the essence part, so as to turn waste into treasure?

Of course, this is just speculation, and the specific situation needs to be further confirmed with actions.

Just do it when you think of it, Lin Xuan poured out a waste pill from the jade bottle, held it in his hand, sat down cross-legged, after the rest just now, the consumption of the sea of stars had recovered, and he remobilized the blue light point to make a big Zhou Tian cycle.

The process was very difficult, but Lin Xuan had long been used to it, and when the point of light reached his wrist, he concentrated his mind and examined it carefully, trying not to miss a single detail.

Under the influence of divine consciousness, the scene in front of him was enlarged several times, and it was clearly reflected in my mind, and one by one the points of light passed through the skin of the palm of my hand, overflowing out of the body, and then some entered the waste pill, and some dissipated in the air.

With the increase of light spots entering the waste pill, some black powder differentiates and separates from the pill, which is impurity.

At the same time, the color of the pill gradually faded, from black to gray, and then to white......

Lin Xuan carefully wrote down every detail, looking at the changes in the elixir, it seemed that his guess should be the same.

At the same time, he also noticed that not all the light points entered the Waste Pill, and some of them dissipated into the air, which was obviously a waste, so Lin Xuan consciously changed the light points in his body and gathered them more closely, so that the number of light points entering the Waste Pill would be more.

Sure enough, the speed of impurity separation was also faster, but after two or three minutes, bang, there was a soft sound, and the pill in the palm of his hand burst open.

Lin Xuan opened his eyes and moved his palm to the front, on which lay a fragmented elixir, emitting a burnt mushy smell, this attempt ended in failure.

"It seems that the blue light dot can indeed separate impurities, purify the essence part, and turn waste into treasure. Lin Xuan muttered to himself, there was no look of frustration on his face, although the test just now was not successful, his gains were not small, confirming his conjecture.

The next thing is to analyze, first sort out the process of controlling the blue light by yourself, there is no mistake, then the reason for the failure, the only possible thing is the speed, could it be that the speed of the light point into the pill is too fast, beyond its bearing?

Lin Xuan made an assumption, and to confirm it, he had to try again, but now the volume of the blue star sea in his body was too small to support the needs of a purification, so it seemed that he could only rest for a while and try again later.
