After all the rune paper has been consumed.

Ye Xuan rested for two hours.

Then he began to learn the art of alchemy with the Mixed Heaven Divine Venerable.

For the art of alchemy.

Ye Xuan has actually been in contact with a lot.

Recently, Ye Xuan's spiritual strength has been greatly improved.

(Author: Drawing inscriptions and refining medicine can improve spiritual power)

Therefore, Ye Xuan was quite confident in learning to refine medicine.

"The quenching pill I taught you is different from the current pill, the pill I taught is the pill recipe of the ancient period, and the value is ten times more precious than the current quenching pill, but the difficulty of refining is also ten times higher, generally speaking, refining medicine needs to have a step-by-step process, and you can't eat it in one step."

"But you're different, your spiritual power is too strong, and you've learned a lot of basic knowledge of alchemy during this time, plus you already have experience in drawing inscriptions and understand the use of spiritual power, so it's no problem to start trying alchemy now."

The Mixed Heaven God Venerable said.

Ye Xuan nodded.

"The first step is to light the stove."

The Mixed Heaven Divine Venerable began to instruct Ye Xuan on how to refine medicine.

Ye Xuan put the earth fire stove on the table, and then turned on the earth fire stove.

At the same time, the power of the soul is fed into the earth fire furnace.

Earthfire is sealed inside the Earthfire Furnace, but these Earthfires are usually just clusters of flames.

It is naturally unrealistic to use a cluster of flames to refine medicine, so you need to use the power of your life soul to activate the earth fire.

The Mixed Heaven Divine Venerable said: "There is an extremely critical point in refining medicine, that is, the control of the fire, the slightest deviation in the fire temperature may destroy this alchemy, so the spiritual power must sense the change in the temperature of the earth fire, and then be able to ensure that you can increase the temperature of the earth fire flame or decrease the temperature of the earth fire flame anytime and anywhere."

"Next is the second step, warm the medicine tripod, put the medicine tripod on the ground fire stove, and calcinate it repeatedly with the ground fire for a period of time, so that the medicine tripod is completely hot, this process is also very important, because the medicine tripod can not be too hot, and not too cold, it needs to be kept at a relative temperature, which is a great test for the monk, what temperature the medicine tripod is maintained, and various medicinal materials are related, therefore, here the alchemist is required to be extremely familiar with the medicinal properties of various medicinal materials."

"Understood".

Ye Xuan responded, and he put the medicine pod on the earth fire stove to calcin.

Ye Xuan's spiritual power had been sensing the temperature of the flames and the temperature of the earth fire furnace.

At the same time, the temperature of the medicine pod is regulated by combining the order of more than a dozen kinds of medicinal materials into the medicine pod successively.

This process is also the process that consumes the most spiritual power.

If you want to become an alchemist, an inscription master, or an alchemist, the requirements for the spiritual strength of the monk are too high, so it is no wonder that alchemists, inscription masters, and refiners are so rare.

There's a reason for that.

......

The temperature of the pod was almost warm.

The Mixed Heaven God Venerable continued, "The next step is to melt the medicinal herbs, wrap the medicinal herbs with the power of the soul and put them into the medicine pod, the scorching temperature will melt the medicinal materials, and the impurities will precipitate at the bottom of the pod, we will only take the spiritual liquid part."

"When the medicinal materials are melted into spiritual liquid, they are more adaptable to the temperature, so even if the temperature changes, they will not be destroyed, but when the medicinal materials are melted, the requirements for the temperature of the medicinal pod are extremely high, and the first medicinal material to be smelted is the Blood Spirit Grass."

The Mixed Heaven Divine Venerable looked at Ye Xuan and asked, "Do you know what to pay attention to when refining the Blood Spirit Grass?"

Ye Xuan said, "First of all, we must pay attention to the temperature of the Earth Fire Flame, the temperature of the Earth Fire Flame should be changed according to the degree of melting of the Blood Spirit Grass, the maximum temperature of the flame is about three hundred and seventy degrees, and the lowest temperature is about three hundred and fifty-one degrees, how to regulate it needs to be judged according to the specific situation."

"Secondly, we should pay attention to the temperature of the medicine pod, the temperature of the medicine pod should be controlled between two hundred and eighty degrees to two hundred and ninety-five degrees, and the specific temperature control also needs to be controlled according to the degree of melting of the blood spirit grass."

"Finally, we must pay attention to the melting degree of the Blood Spirit Grass, because the melting degree of each stage has different requirements for temperature, and it is necessary to adjust the temperature of the flame and the temperature of the medicine pod according to the melting degree of the Blood Spirit Grass."

"Well, let's start smelting the first herb now," said the Mixed Heaven Divine Venerable.

Ye Xuan nodded.

He began to smelt the first medicinal herbs.

All kinds of pharmacological knowledge about the Blood Spirit Grass flashed in Ye Xuan's mind like a horse.

Ye Xuan stabilized his mind and began to smelt the Blood Spirit Grass.

The Blood Spirit Grass was wrapped in the power of the life soul and suspended in the middle of the medicine tripod, and the inscriptions inside the medicine tripod also revived one after another.

These inscriptions are very special, they have the effect of regulating the temperature, and they can also bless the success rate of smelting and condensing.

The core of Yaoding is these inscriptions.

As time passed, the Blood Spirit Grass gradually melted into liquid, and the impurities after melting all fell to the bottom of the medicine pod.

Ye Xuan finally succeeded in melting the first medicinal herb.

Then Ye Xuan began to melt the second medicinal herb.

It took about three hours or so, and Ye Xuan melted all the medicinal herbs.

"Next, we need to fuse all the spiritual liquid together, the melting liquid has high requirements for temperature changes, in addition to the high requirements for temperature changes, there must be no mistakes in the order, but if there is a little error, it will lead to the failure of the solution at that time."

The Mixed Heaven God Venerable continued.

Under the guidance of the Mixed Heaven Divine Venerable, Ye Xuan began to dissolve, and this process was extremely difficult.

But fortunately, Ye Xuan's mental strength was strong, and he took control of the situation and successfully fused all the medicinal liquids together.

The Mixed Heaven Divine Venerable continued, "After the solution is over, the condensation will begin."

"By controlling the fluctuation of the temperature, the fused liquid medicine is condensed into an embryonic pill."

Ye Xuan began to condense the pill.

This process was even more difficult than before, Ye Xuan almost failed, but fortunately, he corrected his mistake in time and successfully condensed an embryo pill.

Seeing that Ye Xuan had condensed an embryo pill for the first time refining medicine, the Mixed Heaven Divine Venerable was still extremely satisfied.

There aren't many alchemy apprentices who can do that.

At the beginning, even if he was talented, he tried more than a hundred times in a row before he succeeded in condensing the embryo pill.

The Mixed Heaven Divine Venerable said, "After condensing the Embryo Pill, you need to refine the impurities inside the Pill."

"This step is the most error-prone step, because this step is to introduce the earth fire into the medicine pod, and then wrap the embryo pill for quenching, the earth fire is hot, and it is easy to destroy the embryo pill, so you must be careful and there can be no negligence."

Ye Xuan nodded.

With a flick of his fingers, a life soul power flew out, and this life soul power flew into the earth fire, enveloping a cluster of earth fire, and the earth fire flew into the medicine tripod under Ye Xuan's control.
