And when using the core rock to start the fire, it is still necessary to pay attention not more or less, if there is more, the flame is too big, and the medicinal materials will be directly burned to ashes.

Of course, it can't be missing, if it is, the flame is not big enough to remove the impurities in the medicinal materials.

So it's not good to be big or small. In fact, it is not easy to control.

I didn't expect that the first time I refined the pill, or even the pill I had already refined, I encountered all kinds of problems.

However, Yun Shirt quickly perked up.

Then he took out some medicinal herbs and threw them into the alchemy furnace in the original order, and then carefully controlled the core rock and threw it into the exit of this earthfire.

With the throwing of the core rock, this flame slammed up, the crimson flame seemed to spit out a small tongue under the purple-red alchemy furnace, and Yun Yi used his divine sense to control the position of this alchemy furnace from the earth fire, if the fire was too big, the alchemy furnace would be lifted slightly.

The fire is small, so she naturally puts it down, but she found another problem, it can be stewed in a pot with ordinary fire, anyway, the recipe is right, and the medicinal effect will not be too bad.

But the elixir of the Immortal Cultivation Realm can't do this.

The medicinal properties of each herb are different, and the temperature at which the useful medicine is extracted is also different.

For example, one herb needs a very high temperature to melt away harmful substances, while another herb can melt harmful substances at very low temperatures.

Therefore, if these two herbs are stewed in one pot, it is obviously a very stupid behavior.

Therefore, Yun Yi reopened the alchemy furnace again, first took out the medicinal materials one by one, carefully sorted the types, sorted them, and then roasted them with earth fire to remove impurities, and ensured that the medicinal liquid was pure, and then threw them into the alchemy furnace.

After the drops of the liquid medicine were thrown in, they soon smelled the rich medicinal fragrance, and after extracting these pure and useful parts, the rest was the process of fusion.

The fusion of liquid medicine is a complex and difficult process.

The properties of each drug are different, some are milder, and some are like wild wolves just after coming into contact with other medicines.

If it weren't for the fact that this alchemy furnace was a treasure in the immortal cultivation world, I am afraid that it would have exploded long ago. At the same time, a certain temperature should be used to maintain the activity of the droplet.

Otherwise, it will not be able to be fused.

Yun Yi quickly played the alchemy trick, which she had only learned.

It's not that Yun Shirt doesn't want to learn, but these effective tips are almost all taught by teachers, and no one will tell others such an important thing at will.

With the help of the laws of heaven and earth, these tricks can play a role in superimposing and strengthening when condensing pills. And these roles should not be underestimated.

Therefore, Yun Yi only knows some simple tricks, and these simple tricks are also helpful to Ning Dan, but they are not as clean and effective as those old alchemists.

But it's better to have a trick than nothing.

In fact, Yun Shan instinctively could also feel that this trick was just to apply the aura to this alchemy furnace better and more effectively.

It's just convenient to control this alchemy furnace.

Isn't this alchemy just about controlling the alchemy furnace and medicinal herbs?

"Ning!" Yun Shirt snorted lightly, only to hear a muffled sound from the alchemy furnace, and Yun Shan's face became a little ugly.

After a while, she moved the alchemy furnace away from the mouth of the fire, and the core rock was almost used, so the fire naturally did not come up again.

Yun Yi opened the alchemy furnace, and the colorful inside of the furnace was as if it had been thrown into the dye vat.

These are all the medicinal liquids that have been refined by Yun Shan, this is because the Ning Dan failed, so these medicinal liquids are scattered in this alchemy furnace.

Yun Yi touched the liquids, feeling the brutal energy inside, wondering what went wrong?

This liquid medicine is so domineering, is it not enough to neutralize the medicinal ingredients?

In fact, alchemy is like this, in the process of failure over and over again, constantly find areas that can be improved. Then, when the refining is successful, you can directly sum up the experience.

And this Pei Yuan Dan and Hua Chun Dan are just ordinary pills, and now they are refined by means of cultivating immortals, and Yun Yi also treats them as immortal pills.

This is not very solemn in my heart.

After a while, she analyzed the reasons for the failure and started the second round of alchemy. This time she became more cautious, and the order of the medicinal herbs was also carefully changed.

In this case, we will be able to prevent the failure of cohesion.

However, theory, no matter what you say, is not as convincing as practice.

So Yun Yi was extra cautious this time. When it was time for the last critical moment, he shouted "Ning!" again, and at this time, Yun Yi stared at the purple-red alchemy furnace tightly, and the alchemy furnace was shocked at this time.

Yun Shirt originally had a little more joy on his face.

Suddenly, there was another muffled sound.

Yun Shan's face turned from joy to sadness again. She suddenly remembered her previous ambitions, and felt that she was quite cute, and even thought that it should not be difficult to think that this alchemy.

In fact, with Yun Yi's IQ, it is not difficult to guess that this alchemist's status in this continent should be quite high. It's just that she has been learning medical skills with Mo Feng, and she can also do alchemy, so she doesn't feel that alchemy is a difficult thing for a while.

That's why it's a little too simple to think about things.

But in fact, things are far from being as simple as she imagined, but there is no way, it has come to this point. If this alchemy step is not good, the possibility of her building a foundation is even smaller.

If she can't succeed in building the foundation, she will be unlucky when she gets out. Yun Yi gritted his teeth, anyway, he had accumulated a lot of medicinal materials, and he would refine them first.

Anyway, the spirit stones have already been handed over, so let's refine them here first, Yun Shan decided that unless the medicinal materials were all used up, she hadn't been able to successfully refine the pill, otherwise he would have been refining the pill.

Thinking so, Yun Shirt was a little more motivated.

Finally, after Yun Yi didn't know how many failures he had experienced, he finally succeeded in refining a furnace of Pei Yuan Dan.

These Pei Yuan Dan are far better than using ordinary refining methods, both in terms of quality and medicinal fragrance.

It is worthy of being refined with earth fire, and the method of using the method of cultivating the immortal realm to remove the impurities in it.

Yun Shan now thinks back to his previous refining methods, and he feels that he is simply a mentally retarded person, and he has wasted all the medicinal materials.

But now is not the time to think about these things, Yun Yi used the same method again, but more carefully refining the elixir, and really this time, there was no mistake.

It seems that things like alchemy also have to be practiced to make perfect.

Yun Yi successively refined several furnaces of Pei Yuan Dan, and then began to refine the Hua Chun Dan, which were all specially used for his own continued strength for spiritual power purification.
