Potion purification

The reason for this is that in the cultivation world, refining pills is a highly skilled task, and even for experienced masters, the success rate is not high, usually one out of three pills will be scrapped, and the scrapped pills, because of the high content of impurities, will not only have no benefit on cultivation after consumption, but will damage the body, so they usually have to be thrown away with pain.

The fact that there are so few spirit herbs and medicines, coupled with the difficulty of refining them and the low success rate, makes pills even rarer.

This is a headache for practitioners, especially in small schools like Piaoyun Valley, where the failure rate is even higher due to the limited skills of the alchemists, and I heard that it is only 50%.

Even cultivators with excellent spiritual roots and diligent cultivators could not do without the aid of pills.

However, for Lin Xuan, this was a great opportunity.

Because these mysterious points of light in the body can be turned against the odds, turning waste into treasure ...

In Piaoyun Valley, for example, there were about three hundred Spiritual Movement stage disciples, each with two Marrow Cleansing Pills per month, a total of over six hundred, but due to refining failures, the waste pills generated would be about that number.

This was the understanding that had developed in the cultivation world over tens of thousands of years. Although the spent pills from failed refineries were not thrown away freely, their management was very chaotic and no one paid attention to them, so Lin Xuan hit on the idea of these spent pills.

There were six hundred spent pills per month, if one could get one's hands on them and then use blue light dots to turn them into useful spiritual medicines ...

This way, one could use the pills as sugar pills, and even if one did not have spirit roots, one would still be able to cultivate faster than his fellow disciples.

The prospect was very rosy, but Lin Xuan did not get hot-headed, even at this time, he kept very clear-headed and planned and planned for what he should do next.

The first thing was to find out the cause, how a spent pellet had become a precious elixir, the reason must be clarified, what conditions were needed, how to control the blue light dot, to understand the process, otherwise the wonderful vision just now would be a mirror, visible but not touchable, in short the use of the blue light dot needed to be well mastered.

Having decided on his target, Lin Xuan put the elixir in front of his eyes and observed it carefully.

The colour, the fragrance, there was no mistake, apart from the last time he was given a hard time by Elder Ma, Lin Xuan had taken lower grade Marrow Cleansing Pills before, so he would never be mistaken.

To be on the safe side, he also took out a genuine Marrow Cleansing Pill from his storage bracelet, which he had collected from Zhou Yan, and compared the two.

Compared to the authentic Marrow Cleansing Pill, the only difference was that this pill, which was changed from a waste pellet, was slightly smaller in size, and next to it was a pile of black, gooey powder that emitted an unpleasant smell, which caught Lin Xuan's attention.

Impurities?

Of course Lin Xuan would not let go of such an important detail and recognised its origin quite accurately. The reason why spirit pills made from rare herbs would be scrapped was because the spent pills contained too many impurities.

In other words, there was not a lot of essence in the spent pills, but the impurity content was too high and affected, which was why they were useless for cultivation.

If the impurities could be removed from the spent pills and the essence purified, the spent pills could also be turned into elixirs, but this is only theoretically easy to say, but in practice it is more difficult than climbing to the top.

After countless failures, cultivators also gave up and could only painfully discard the waste pills. For tens of thousands of years, the cultivation world has cultivated the understanding that the impurities in the waste pills cannot be removed.

But in front of him, that pile of blackened powder was clearly impurities!

Lin Xuan pondered for a moment and began to make bold assumptions, could it be that the function of the blue star sea within his body was to purify, remove the impurities and concentrate the essence out, thus turning waste into treasure?

Of course, this is only a guess, and the exact situation needs to be further confirmed by action.

Lin Xuan poured out another waste pellet from the jade bottle, held it in his hand and sat down on his knees. After the rest he had just taken, the consumption of the Star Sea had been restored, and he re-mobilised the blue dots of light to perform the Great Circulation.

The process was very difficult, but Lin Xuan had long been used to it. When the light dots reached his wrist, he concentrated his divine sense and examined them carefully, trying not to miss a single detail.

Under the effect of his divine sense, the scene in front of him was enlarged several times and clearly reflected in his mind. One by one, the light dots passed through the skin of his palm and spilled out of his body, then some went inside the waste dan, while others dissipated in the air.

As the number of light dots entering the waste pills increased, some black powder split and detached from inside the pills, these were the impurities.

At the same time the colour of the pills gradually faded, turning from black to grey and then to white ...

Lin Xuan took note of every detail with care, and looking at the changes in the pills, it seemed that his guesses should be right on the money.

At the same time he also noticed that not all of the light dots entered the waste pills, there was still a part that dissipated inside the air, which was obviously a waste, so Lin Xuan consciously changed the light dots inside his body, gathering them more closely so that the number of light dots entering the waste pills would be higher.

Sure enough the impurities separated faster as well, yet two or three minutes later, bang, a soft sound, the pills in his palm burst open.

Lin Xuan opened his eyes and moved his palm in front of him, on top of which lay the split spirit pills, emitting a burnt and mushy smell, this attempt had ended in failure.

"It seems that the blue dot of light can indeed separate impurities and purify the essence part, turning waste into treasure." Lin Xuan muttered to himself, without the slightest look of frustration on his face, although the experiment just now had not been successful, he had not gained much, confirming his suspicions.

The next step was to analyse it, first combing through the process of controlling the blue light himself, there were no mistakes, so the only possible reason for the failure was speed, could it be that the light point was entering the elixir too fast, beyond what it could bear?

Lin Xuan made a hypothesis, and the only way to confirm it was to try again, but the volume of the blue sea of stars in his body was now too small to support what was needed for one purification, so it seemed that he had to take a break and try again later.
