第十四章 丹药提纯

In the cultivation world, alchemy was a highly skilled task. Even experienced experts had low success rates; typically, out of three batches of pills, one would fail. Waste Pills, due to their high impurity content, not only offered no benefits but also harmed the cultivator's body, usually resulting in discarding them with pain.

Various spirit herbs and medicinal materials were scarce, making alchemy even more challenging. This scarcity made pills extremely rare.

This caused headaches for cultivators, especially those from small sects like Drifting Cloud Valley, where alchemists had limited skills, leading to higher failure rates—around 50%. Even common, low-grade Essence Cleansing Pills could only be provided in small quantities each month, just two per disciple.

The scarcity of pills was a significant factor hindering the improvement of cultivators' abilities. Even those with excellent Spirit Roots and great diligence still relied on pills for support.

However, this presented a massive opportunity for Lin Xuan.

Because the mysterious light points within him could defy nature, turning waste into treasure...

Taking Drifting Cloud Valley as an example, there were roughly three hundred灵动期disciples, each receiving two Essence Cleansing Pills per month, totaling about six hundred. Due to failed alchemy, the number of Waste Pills generated was also around this amount.

Waste Pills were harmful and useless; they were mere trash. This understanding had been formed in cultivation circles over thousands of years. Although waste pills weren't discarded randomly, management was chaotic, and no one paid attention. Thus, Lin Xuan began to eye these waste pills.

With six hundred Waste Pills each month, if he could obtain them and transform the blue light points into useful spirit medicines...

This would allow him to treat pills like candy, significantly boosting his cultivation speed even without a Spirit Root compared to his fellow disciples.

The prospects were bright. However, Lin Xuan did not get carried away. Even then, he remained highly alert, formulating plans for what he should do next.

Firstly, he needed to explore the reasons behind the transformation of Waste Pills into valuable spirit medicines. He must understand the conditions required and how to control the blue light points. Otherwise, his beautiful设想would be like mirages—visible but unattainable. The usage method of the blue light points needed careful mastery.

Having set his target, Lin Xuan placed a pill in front of him and examined it carefully.

The color and scent were correct; he had previously ingested inferior Essence Cleansing Pills and would not mistake them for anything else.

To be safe, he took out another genuine Essence Cleansing Pill from his storage bracelet. This one was obtained from Zhou Yan. Comparing the two,

Compared to the authentic Essence Cleansing Pills, this transformed pill was slightly smaller in volume, with a pile of black powder around it, emitting an unpleasant odor that caught Lin Xuan's attention.

Impurities?

Lin Xuan did not overlook such crucial details and accurately identified their origin. The reason why spirit pills made from rare herbs often failed was due to the high impurity content in Waste Pills.

In other words, while the essence part of the pill wasn't lacking, it was the excessive impurities that rendered them ineffective for cultivation.

If he could remove these impurities and purify the essential parts, Waste Pills could be transformed into spirit medicines. However, this was merely theoretical; despite its simplicity, actual implementation was far more challenging than climbing to heaven. Over thousands of years, many attempts by major sects and scattered experts had failed.

After countless failures, cultivators gave up, reluctantly discarding their waste pills. Over thousands of years, the cultivation world had come to accept that impurities in Waste Pills could not be removed.

But before him lay a pile of black powder—clearly impurities!

Lin Xuan pondered for a moment and began making bold assumptions. Could the blue sea within his body's function be purification, removing impurities, and concentrating the essence parts to transform waste into treasure?

Of course, this was just speculation; the exact situation needed further verification through action.

With that in mind, Lin Xuan poured another Waste Pill from his jade bottle, held it in his hand, sat cross-legged, and after a brief rest, the blue sea's consumption had recovered. He reactivated the blue light points to perform Grand Circulation.

The process was difficult, but Lin Xuan was accustomed to it. When the light point reached his wrist, he focused his spirit essence, carefully observing every detail.

Under the influence of his spirit essence, the scene expanded several times, clearly imprinted in his mind. Light points passed through the skin of his palm and overflowed from his body, some entering the pill, while others dissipated into the air.

As more light points entered the pill, black powder began to separate and detach from it—these were impurities.

Meanwhile, the color of the pill gradually faded, turning from black to gray, then white...

Lin Xuan meticulously recorded every detail. Watching the changes in the pill, he concluded that his guess was likely correct.

He also noticed that not all light points entered the pill; some dissipated into the air, clearly a waste. Thus, Lin Xuan consciously adjusted the blue light points within him to cluster more tightly, increasing the number entering the pill.

Sure enough, the rate of impurity separation sped up. However, after two or three minutes, with a soft sound, the pill in his palm exploded.

Lin Xuan opened his eyes and moved his hand forward, revealing four pieces of charred spirit pills on it. This attempt ended in failure.

"Seems like blue light points can indeed separate impurities and purify the essence parts to transform waste into treasure," Lin Xuan muttered, showing no signs of disappointment. Although this experiment had failed, he gained valuable insights that confirmed his hypothesis.

Next came analysis. He reviewed the process of controlling the blue light points without errors. The only possible reason for failure was speed—could it be too fast an entry rate exceeding its capacity?

Lin Xuan made a hypothesis and needed to verify it by trying again. However, the volume of the blue sea within him was already too small, insufficient for purification. He decided to rest before attempting again.
