Yun Yi looked at the reactions of the others, and suddenly felt a little inexplicable.

There is no problem with this medicinal material, it is completely capable of refining the three-pattern pill 'Essence Bone Pill', how can they be worried, isn't there something greasy in it?

The medicinal herbs provided by the temple are indeed not a problem. The alchemist pays attention to the character of the medicinal materials. It's too low-grade, the year is too low, and even if the pill is refined, the medicinal properties are too weak.

Even if it belongs to the three-pattern pill, it is the lowest grade one. The rate of Chengdan is also much lower than that of high-vintage medicinal herbs.

Yun Yi didn't understand this at all. He had only been practicing the pill for a little more than two days, and all he had mastered was the part of the pill that he had interpreted. He's a quick hit, and others have been doing it for years.

As for the characteristics of medicinal materials, how to identify them, Yun Yi is completely unknown.

The alchemists in the field should be stronger than him in terms of medicinal materials.

He didn't have the time to pay attention to others. The first scene was to refine the three-pattern pill, and the medicinal materials provided by the temple were just up to the requirements.

As soon as he realized the movement, the five elements of the spiritual aura in the spirit mansion responded one after another.

He glanced at the Dan furnace on the table and automatically ignored it. To refine the elixir, a Dan furnace is needed, which is something that almost all alchemists are familiar with and consciously should do.

But Tang Rui doesn't think so.

To refine the elixir, you need to use the essence contained in the medicinal materials. And the best way to preserve this essence is not to come into contact with any substance, and if it is a last resort, it is best to wrap it in aura.

No matter what kind of Dan furnace, it has its own attributes, the soil system Dan furnace is quite heavy, and the special metal Dan furnace is quite heavy.

Once these Dan furnaces come into contact with the essence of medicinal herbs, they are bound to destroy the medicinal properties.

Therefore, as soon as Yun Yi came up, he used his aura to condense a Five Elements Dan Furnace. There is no need to worry about destroying the properties of the medicine.

Next, he urged his mind, condensed the aura of the water system, and obtained the purest water.

Yun Yi's method of refining the elixir was completely learned from Tang Rui. Tang Rui's trick to alchemy is in one word, boil. Throw all the herbs into the water and boil out all the essence of the herbs as if they were boiling a decoction.

This method is not a difficult task for plant medicinal materials. However, it is not easy to achieve the bone medicinal materials of animals or birds.

Tang Rui's method is even more simple, that is, to make it into crushed powder and choose it slowly.

Yun Yi was curious, wouldn't it be better to calcinate it with a different fire?

As a result, he was scolded. Tang Rui said that the elixir is for living beings, and if the essence of the medicinal materials is not even afraid of different fires, how can living beings absorb it if they take it? Could it be that the viscera of living beings is stronger than different fires, isn't this nonsense?

With this, Yun Yi lost his temper.

To screen the essence of medicinal materials, it must be the same, and when it is completely extracted, it is the time when the strange fire really comes into play.

With a bang, a pure blue, unvariated flame appeared in Yunyi's palm. According to Tang Rui's judgment, this should be regarded as a blue heart exquisite fire. This strange fire was first discovered in a piece of exquisite jade.

It is rumored that the discovery of this flame led to an era, and it was after the Blue Heart Exquisite Fire that the way of the elixir entered a new world.

As soon as the flames of the cloud wings came out, the people around him looked sideways. When they saw the color, they couldn't help but stare at it.

Pure blue flame? Could it be a blue heart fire? Hasn't this fire been gone for thousands of years? Why did it appear again?

After the Blue Heart Exquisite Fire, the alchemist gradually discovered other kinds of flames. In comparison, Linglong Fire is too warm, just like a gentle woman, she needs to get along for a long time to find its beauty.

This kind of flame refining elixir consumes too much patience and energy, and is not as fast and fierce as other mutant flames.

Seeing that Yun Yi was already busy, no one paid attention to him. Isn't it great to have an antique flame? It's nothing more than nostalgic for people, and it doesn't help much in refining pills.

Puff, puff, continuous flame burning sound resounded in the room. The temperature on the playing field rose sharply.

At this juncture, no one observes the others anymore, and they concentrate one by one.

Yun Yi held the Dan Furnace with one hand and added medicinal materials to the Spiritual Qi Dan Furnace with the other.

Under the torment of the blue heart exquisite fire, the water in the Dan furnace boiled, and the medicinal herbs began to release medicinal properties. This is not enough.

There is a standard for the rootless water added to the Dan furnace and must be boiled in its entirety.

An hour had passed, and all the medicinal materials used in a pill had been refined and turned into medicinal powder. Next, there is Rong Dan. Let all the medicinal herbs and essences be integrated into one.

This is the most critical step, and it is a test of the alchemist's control over the heat.

The fire should not be too big, it should reach a degree. It can melt the essence of the herbs, but it can't burn it.

The melting point of the essence of medicinal herbs is not the same, which requires different temperatures and different flames.

Yunyi has changed its strategy. The blue flame in the palm of his hand was extinguished.

A flame appeared on the tip of the index finger, it was no longer pure blue, and there was a white flame mixed in it. This is a flame that is warmer than the blue heart exquisite fire, and it also has a violent temperament.

The first kind of powder floated into the air under the control of consciousness. Yun Yi carefully moved his index finger and began to heat up.

This process requires extreme concentration and care. If you don't pay attention, the herbs will be destroyed, and everything will have to be restarted.

The powder began to melt slowly.

At this time, Yun Yi's hand quickly sacrificed the second medicinal powder. On the tip of the middle finger, a flame also appeared, which was still mainly blue, but with a touch of orange.

The two medicinal powders were clearly suspended, and the two flames were constantly heated, and the two medicinal powders finally slowly melted, and finally mixed together.

At this moment, Yun Yi sacrificed the third medicinal powder, and the ring finger also shone with fire, and the color changed again, with a touch of yellow in the blue.

Soon, all four of Yun Yi's fingers were in flames, and all the medicinal powders were also thrown in, and they were rapidly melting, merging, and becoming one. It's just that it's full of pimples, and it's extremely ugly.

The Rongdan step is considered complete.

Melting pills is just one step in alchemy. The essence of medicinal herbs is simply fused, but they do not complement each other into a whole.

The next step is to wash the Dan.

Not with water, but with fire. Wrap the entire pill with flames, and let the ingredients of the pill slowly merge.

The key to this step lies in the order of Rongdan before. The powder with a high melting point is on the outside, and the powder with a low melting point is on the inside.

When washing the pill, the residual temperature of the flame outside will penetrate in, causing the entire pill to melt into a whole.

With a bang, Yunyi put away all the flames, and new flames burned in his palms again, mainly blue, supplemented by light red. The elixir hangs in the palm of your hand.

As the washing pill began, the faint fragrance of medicine began to waft around.

Cloud Wing's location was so remote that almost no one could notice him. This kind of atmosphere of doing things quietly and not being disturbed by outsiders is very in line with his temperament.

It didn't take long, and a round pill with a special fragrance was formed.

Yun Yi hurriedly put it away in the jade bottle. He finally had a chance to observe other people's alchemy processes.

When he looked sideways, he saw that the people around him were staring at him. He frowned in surprise, "What are you looking at?" )
