At the foot of Xingzhu Peak, around the mountain is a row of Dan houses, with the room as the array, and the array as the room, gathering the fire spirit qi within a radius of hundreds of miles nearby, and injecting it into the Dan furnace to enhance the firepower of refining spiritual materials.

It's just that renting such a Dan room, more than ten spirit stones per month, and it will take about a few months to wait for an idle alchemy, so it is not something that ordinary casual cultivators can afford.

After settling Wei Yunshui again, Zhang Yuan paid one hundred and twenty spirit stones and began a year-long closed-door alchemy.

Soon, he found that this was a curious science, if the various alchemy terms were simplified and described in one sentence, that is, to urge different degrees of spiritual fire, extract different medicinal properties between different spiritual materials, transform and blend with each other with the mutual effect between medicinal properties and characteristics, and subtly grasp the balance therein, in order to achieve complete success.

Zhang Yuan flipped through a volume of the Dan prescription he bought, glanced at it roughly, and then chose the first pill and started to try it.

The most basic kind of elixir is the elixir, which is inexpensive, and it is a low-level pill commonly used by monks in the condensation period to replenish the spiritual power of the qi sea, and the main spiritual materials used are chrysanthemum grass and spiritual green buds that have a very short growth cycle and are easy to cultivate.

According to the Dan formula, he took out the corresponding spiritual materials, placed them in a place similar to a heavenly scale in the Dan furnace, and then placed the five-colored mud tanned into a round ball-shaped shape in the center, Zhang Yuan carefully urged the spiritual power to activate the blue and white flames at the bottom of the furnace.

Five-color mud is a special kind of mud that appears under the nourishment of the five elements of spiritual energy in the world of cultivation, and it is also a necessity required for refining most of the pills.

More than 80% of the spiritual materials in the world, the five-colored mud can accommodate and absorb, from low-level such as the Transformation Spirit Pill to the rare Zhuji Dan, etc., all of which are inseparable from this material.

Under the thick and simple Dan furnace, the blue and white spiritual power fire was blazing, Zhang Yuan carefully controlled the spiritual power in his body, so that the spiritual fire was inhaled from the nine dragon head mouths of the Dan furnace in turn, and after the layers of filtration inside the dragon body, the flame and the spiritual material collided together, and a stream of mixed medicinal power emanated from it, and gradually converged into the five-colored mud in the center under the effect of the Dan furnace.

The quality of a pill lies in whether the medicinal properties are pure, and the residual degree of drug poison and impurities.

For most pills, the cultivation realm is generally divided into three grades according to their medicinal properties: finished products, high-quality products, and excellent products.

The finished product is only usable, the high-quality erysipelas is almost none, and the good product not only does not have erysipelas, but also has its own medicinal properties to the greatest extent.

According to the various techniques and rules on the Dan Fang, Zhang Yuan did it one by one, and after half a quarter of an hour, there was a muffled sound in the Dan furnace, and you didn't need to look at it to know that this was a bit more intense, and the Dan Pill exploded.

Failure is normal, Zhang Yuan is not discouraged, after cleaning up the Dan furnace, he continued to add spiritual materials to it, and started the process just now......

Fail!

Fail!

Fail again!

Just as he was about to start the fifth time, Zhang Yuan's heart suddenly moved, and he peeked into the furnace with the Yang God Vision, and this time, his vision not only penetrated the furnace body, but also saw the operation and route between the aura and the medicinal power clearly!

In terms of technique and medicinal familiarity, this means that he has skipped the long period it takes to go from novice to master!

The famous Danshi also has the eye technique of the Inner Pill Furnace, but unlike him, he can even see the route of the medicinal properties and spiritual fire clearly, although this is not a big deal, but it can save a lot of time and materials in the early stage.

In the Dan furnace, the five-colored mud gradually changed color, this is in the critical period of convergence and fusion of medicinal properties, Zhang Yuan watched all the changes inside, and his quiet gaze revealed calmness.

As the medicinal power in the spiritual material was dissipated, the five-colored mud turned into a pale green pill under the effect of the medicinal properties, and a wave of accumulated spiritual energy emanated from within, which was obviously done!

Zhang Yuan was slightly happy in his heart, took out this pill and observed it in front of him, and deduced that this was a high-quality elixir based on its color and taste.

"For the first time, I have to eat it. Zhang Yuan rubbed it for a moment or two, then swallowed it into his abdomen, meditated to restore more than half of the spiritual energy consumed in his body.

After being familiar with the process of transforming the elixir, he began to refine a higher level of the Sealing Elixir, this elixir has a miraculous effect, that is, it does not immediately take effect after swallowing it in the abdomen, it can be stored in the body for a month, according to the needs of the monk to decide whether to dissolve the medicinal power, suitable for use before embarking on the journey, in preparation for the depletion of spiritual power in the body.

It's just that the difficulty of refining this pill is much higher, and even under the effect of internal vision, it still took Zhang Yuan nearly two days to master it.

Time passed quietly in failure and success, and unconsciously, Zhang Yuan had become a qualified Danshi, and in the vast world of cultivation, this was also a rare speed of progress, and with this skill, no matter which sect he was in, he could find a place.

One success and one failure, one drink and one peck, there is a lot of fun, which attracts many people to be obsessed, and they do not hesitate to waste their cultivation.

As for Zhang Yuanyuan, although the fun of alchemy can also make him tireless, he knows very well that this is just a means to climb the avenue, and he will never reverse the distinction between the main and the auxiliary.

Nine months later, all the spiritual materials for practicing have been consumed, and in the continuous burning of massive spiritual materials, Zhang Yuan, who has accumulated rich experience, also set his sights on the last batch of materials.

He turned into a Dao Jidan, and he was finally about to start refining.

The other person takes from external things, from heaven and earth, to make up for the shortcomings of his own body.

This is on the basis of the orthodox Zhuji Dan, adding the ingredients of catalyzing the demon Inner Dan, so as to seize the Inner Dan Dao Yun accumulated by the demon swallowing heaven and earth, and "transform" it into his own Dao Ji!

This kind of elixir that seizes creation is not tolerated by the Great Dao of the Underworld. The difficulty of refining has increased tenfold, which can be described as three points of manpower and seven points of destiny, which can no longer be controlled completely by experience and techniques. And Zhang Yuan had already collected as many spiritual materials as possible, which was only enough for six refining.

Six chances, can it be successfully refined?

Zhang Yuan slowly closed his eyes, and the whole person entered a state of silence. In the past nine months, all kinds of experiences, subtle and subtle mysteries have flowed again in the heart, and they have re-peeped into the traces of the Holy Body, analyzed the creation of heaven and earth, and comprehended the middle path.

Three days passed, Zhang Yuan sat alone in the empty Dan room, and a beam of spiritual light shot from the roof, which happened to shine in the center of the Dan furnace, reflecting the entire furnace in a faint halo.

Suddenly, he opened his eyes, and with a wave of his big sleeves, all kinds of spiritual materials suddenly appeared in front of him.

Alchemy begins!
