These medicinal powders of different colors are all the products of the refining of elixirs, and the next thing to do is to fuse these medicinal powders together in order to complete the Ning Dan.

The process of condensing pills is the most difficult step in alchemy, and if you are not careful, it will lead to the failure of condensing pills, all efforts will be wasted, and those rare elixirs will also become useless wastes.

Chu Yun took a deep breath, he had just refined so many elixirs in a row, and the true yuan in his body had really consumed a lot, and after making some adjustments, he silently recited the Dharma decision in his mouth, pinching the trick like a wheel with ten fingers, and a stream of spiritual light shot out from Chu Yun's fingers and fell on the alchemy furnace.

Suddenly, the originally calm alchemy furnace began to hum, and at the same time, the furnace body shook slightly, and the temperature of the entire room began to rise sharply, and beads of sweat like beans appeared on Chu Yun's forehead.

Throughout the process, Chu Yun's powerful soul power always tightly wrapped those elixirs, and the magic decision in his hand also changed with the changes in the alchemy furnace.

"Condensation!"

Chu Yun let out a low cry in his mouth, and the magic in his hand changed suddenly, and one after another spiritual light rushed into the alchemy furnace in front of him along Chu Yun's ten fingers, and suddenly the entire alchemy furnace began to shake violently.

However, after only a blink of an eye, the alchemy furnace, which was still shaking, suddenly let out a humming sound, and then there was no movement, and at the same time, Chu Yun's hand pinched the ground and stopped.

"Enlightenment!" Chu Yun let out a low cry in his mouth, and then pointed with one hand, only to see the alchemy furnace dripping and turning, and the lid suddenly opened.

Suddenly, a strong medicinal fragrance came up, and the smell couldn't help but make people feel shocked, Chu Yun sniffed deeply with his nose, and his face showed a hint of joy, if nothing else, this time the alchemy should be successful.

Thinking of this, Chu Yun walked quickly to the alchemy furnace, looked sideways, and saw that there were seven blue-brown pills the size of a dragon's eye quietly placed in the furnace, each of which exuded a strong medicinal fragrance, and the appearance was smooth, and the color was also very bright, at first glance, it belonged to that kind of boutique.

Seeing this, Chu Yun made a move with one hand, and the seven pills flew into Chu Yun's hand with a swish, and then put them in his hand and looked at them carefully, then patted the storage bag, took out a white jade bottle from it, and poured all the pills in his hand into it, with a satisfied expression on his face.

This time the alchemy was very successful, there were as many as seven Cheng Dan, and the grades were all high-grade pills, this result was really rare for him, a person who was alchemizing for the first time.

Dan Fang from the beginner to the intermediate, in the advanced Dan Fang, as well as the rumored Heavenly Rank Dan Fang, the higher the level of the Dan Fang, the more difficult it is to refine, of course, correspondingly, the greater the benefits.

For example, the Heavenly Rank Pills, for the cultivation of the Heavenly Rank cultivators, have a very significant improvement, and those primary pills can only work on the monks below the Xuan Rank, after the cultivation reaches the Xuan Rank, the medicinal power contained in the primary pill can almost be slightly ignored.

Because of the different methods of refining the elixir, the same elixir is divided into lower-grade, medium-grade and high-grade, and the medicinal power contained in a high-grade pill is enough to be equivalent to the medicinal power of more than ten lower-grade pills, and the value is naturally more than ten times that of the lower-grade pills, and some special pills are even dozens of times higher.

The method of distinguishing their grades is very simple, each pill retains three-tenths of the efficacy, that is, the lower grade pill, more than five-tenths belongs to the medium-grade pill, only the efficacy of more than seventy percent, can be called the top grade pill.

It is said that on top of the high-grade pills, there is also the legendary Dao Dan, which can be called Dao Dan only if the medicinal power of ten percent of the medicinal effect is exerted.

Some people may want to say, why do you have to refine it into an elixir and take the elixir directly, won't you be able to absorb all the medicinal power?

In fact, the elixir that has not been refined contains many impurities, and if you take it directly, it will not only greatly reduce the medicinal power, but it is even very likely to have the opposite effect.

Only when it is combined with many auxiliary elixirs and refined into a pill, can the medicinal power be brought into the best state, even if it is just a low-grade elixir, it is much stronger than the effect of taking the elixir directly, and there is more than one Cheng Dan refined.

Therefore, under normal circumstances, the elixir is refined into a pill, and unless there are special circumstances, no one will directly take the elixir.

Chu Yun was still quite excited about his first alchemy and successfully refining a top-grade elixir, and he had to sigh that Sima Changfeng did have two brushes in alchemy, and he was able to reach this level just by relying on some of the concepts and skills he had instilled in him, which showed that his attainments in the way of alchemy were at the pinnacle.

Of course, after Chu Yun fused the memories of his previous life, the power of his soul skyrocketed, and his ability to control flames was extraordinary, which led to this result.

Then Chu Yun tried alchemy again, maybe because he had the first successful experience, his heart was much more relaxed, or maybe it was because there was not much true yuan left in his body, and this time the refining failed.

However, Chu Yun was not discouraged, after summing up the experience of failure, he put the alchemy furnace into the storage bag, and during the two consecutive alchemy processes, the sky outside had already brightened up unconsciously, although cultivators could rely on meditation and cultivation instead of sleep, Chu Yun still felt a wave of tiredness coming.

After packing up everything, Chu Yun lay on the bed and fell asleep, and it was not until noon that he woke up from his sleep.

The first thing I did when I woke up was to say hello to my mother, and then I went back to my room and prepared to continue my cultivation.

Chu Yun, who was sitting cross-legged on the futon, was playing with a brown pill the size of a dragon's eye in his hand, which was the Heavenly Spirit Pill he had refined yesterday.

Heavenly Spirit Pill, for a Yellow Rank Cultivator, can be significantly improved after taking it, but for a Xuan Rank Cultivator, the improvement can be slightly ignored.

After thinking for a moment, Chu Yun no longer hesitated for anything, opened his mouth and swallowed the pill in his hand, then slowly closed his eyes, hugged Yuan Shouyi, and activated the Jiuyang Divine Skill.

As the pill entered his abdomen, a strong spiritual power immediately spread out in Chu Yun's abdomen and began to flow along the meridians, because the spiritual power contained in the top-grade Heavenly Spirit Pill was too huge, Chu Yun only felt that the meridians seemed to be about to burst, and there were bursts of burning pain.

However, fortunately, Chu Yun, who had condensed his blood, had a body strength far from being comparable to that of a monk of the same level, and with a gritted tooth, he activated the Jiuyang Divine Skill and began to absorb the medicinal power of refining the Heavenly Spirit Pill.
