When he got up early the next morning, Gu Feng began to prepare for alchemy, sorted the medicinal materials and prepared them, and cleaned the pottery furnace used for alchemy.

Alchemy in reality is not as cool as it is written in the novel, and the first step is to put the medicinal herbs into the furnace to boil.

Gu Feng refines the "True Yang Pill", which, according to the records, is mainly composed of four steps.

A portion of Danfang, divided into three parts, part of the herbs, put into the oven and boil.

The other part of the medicinal materials is polished into powder for later use, and the last part of the medicinal materials is boiled into medicine and used in the final step of alchemy.

The first step is to boil the medicinal materials for more than an hour, boil out the medicinal properties in the medicinal materials, and pour out the medicinal residue.

Strain out the medicinal soup with the residue removed, continue to boil in the oven, add a certain proportion of wild honey, and boil it into a paste.

After boiling the medicinal soup into a paste, the first step is completed, followed by the second step, "Hedan".

The so-called "Hedan" in this second step is actually to pour the part of the medicinal herbs that were previously polished into powder into the ointment evenly, and stir the bamboo slices evenly.

Until the viscosity of the ointment is neutralized by the powder, just like kneading dough, the viscosity of the poultice is reduced and does not stick to the bamboo chips, and the "Hedan" is completed.

After "He Dan", the third step is "Cheng Dan", and the "Cheng Dan" here is not like in the novel, which is manipulated with spiritual power and condensed into Dan.

That method is too cool, Gu Feng can't do it at the moment, and the Cheng Dan method he is currently using is to divide the prepared utensils evenly into forty-nine parts.

Then, with a small bamboo tube that has one-third cut off, a portion of the medicine ball is incorporated into the bamboo tube, and the bamboo tube is quickly turned so that the medicine ball inside is stirred into the shape of a pill.

The method used in this third step of "Cheng Dan" is so earthy, which is far from the legendary cool alchemy method.

After the forty-nine pills were stirred into pills of similar size, the next step was the most critical step, "Qin Dan".

This key step "Qin Dan", success is the pill, and the medicinal properties are perfectly brought into play.

The loser fries the oven, or the pill is scorched, and it becomes a waste pill.

Gu Feng took out the pottery furnace that he had modified with his own hands, heated it in the stove, and put forty-nine pills into the furnace.

took a deep breath, the success of alchemy or not depends on this step.

The medicine that had been boiled before was sprinkled thinly in the furnace and stirred with bamboo slices to make the elixir inside absorb the medicine in it evenly.

The so-called "Qin Dan" is actually to put this last medicine into the pill to make the medicinal properties complete.

After all, a pill is divided into three parts, and only when the medicinal properties of the three parts are combined together can it be regarded as a complete refining pill.

The step of "Qindan" is very important, and the key lies in the control of the heat.

After sprinkling the potion into the furnace, Gu Feng observed that the potion in the furnace was only a thin layer, and even after heating, there would not be too much heat.

Close the lid of the furnace, plug the gas outlet of the pottery furnace, slowly heat the medicine inside, evaporate the hot gas, and slowly dip into the elixir.

For this last step of alchemy, Gu Feng opened a small hole in the top of the lid of the pottery furnace, installed a bamboo stick, and then closed the small hole tightly to ensure that there would be no air leakage.

This bamboo stick has a great effect, and it is used to continuously stir the pills in it during the "Qin Dan" process to make it absorb evenly.

Gu Feng touched the temperature of the pottery oven with his hands from time to time, once it was too high, he had to reduce the charcoal fire, otherwise if the temperature continued to rise, the furnace would be fried.

This is the most critical step, completely relying on experience, Gu Feng's first alchemy, experience is equal to zero, but he can control the pottery furnace within a certain temperature, ensuring that the furnace will not be fried.

It's just that this last step "Qin Dan" not only has to ensure that it will not be fried, but also that the pill inside will not be burned.

After the pill is absorbed, it is still necessary to continue to dry it in a high-temperature furnace to complete the drying process, and evaporate the water in the pill, so as to ensure that the pill can be stored for a long time and ensure that the medicinal properties are not lost.

At this point, it is necessary to open your mouth once in a while to let go.

This also depends on experience, if you deflate early, you will lose the medicinal properties and reduce the efficacy of the pill.

If the deflation is late, the pill will appear scorched black on a certain period of dù, and the medicinal properties will also be lost, and even contaminated with heat poison.

Gu Feng slowly stirred the bamboo stick on the stove lid, and at the same time, he relied on his hand and sound to identify the situation in the furnace, so as to deflate the gas in time.

This series of alchemy steps is simple to say, but it is extremely tedious and takes a whole day.

Gu Feng was so tired and sweating profusely that he didn't even eat lunch, from the time he prepared the alchemy in the morning until now.

Especially the alchemy burning firewood, the smoke and fire, Gu Feng's face was full of smoke and dust at this time, and he was even more sweaty by the fire.

Alchemy alone is indeed too tiring, all kinds of steps need to be prepared by yourself, and there is not even a helper, so you can't be idle for a moment.

Gu Feng thought at this time, no wonder there were so many cultivators in ancient times, all of them had children to serve, it turned out that when alchemy, these boys could help them, otherwise they would be tired alone.

Do you want to find a boy yourself? Liu Menghe? Belch...... How did you think of this girl?

However, the next time you do alchemy, it seems good to find someone to help you get started?

Gu Feng was full of thoughts at this time, sighing at the hard work of alchemy, he was almost tired of this whole day's work, and prayed in his heart, don't fail this alchemy.

It feels almost over, loosen the clogged air holes, let go of the gas for a few seconds, and block it again.

The charcoal grill in the stove was pulled out, and the final stage of alchemy was entered, and the furnace began to cool down.

After a while, the air hole was opened again, and this was repeated several times, until after the hole was opened, no gas was released, but a faint medicinal fragrance came, which was the end of alchemy.

Gu Feng smelled the faint medicinal fragrance coming from the Dan furnace, suppressed the excitement in his heart, and slowly opened the Dan furnace.

Suddenly, a strong medicinal fragrance came to the nostrils, penetrated the heart and spleen, and the whole person couldn't help but feel refreshed, as if the fatigue of a busy day was swept away.

In the Dan furnace, forty-nine pills the size of a little finger were lying quietly in the furnace, and the appearance of the dark pill did not lack a round luster.

Gu Feng took out a pill and spread it in the palm of his hand to look at it carefully, it was black and shiny, there was still residual warmth, and a faint medicinal fragrance wafted in.

Danxiang is fragrant but not strong, light but not scattered, lingering in the air, as if it can moisten people's minds.

Gu Feng took a deep breath and couldn't help but grin and smirk, this first alchemy was successful!

Although Danxiang is not as rumored, Danchengxiang floats for ten miles, but it also floats for at least a few hundred meters without dispersing, right?

Gu Feng was intoxicated with the incense of the Dan, and for a long time, he took out the pill in the Dan furnace and put it into the porcelain bottle that had been prepared long ago.

One pill was the size of a little finger, forty-nine pills, and it contained two small porcelain bottles.

Gu Feng held these two porcelain bottles in his hands, and the tiredness of the day was swept away, and what was contained in them was the "True Yang Pill" that he had refined by himself!
