"Yawn!"

The disciple on duty, dressed in short clothes and with short hair, yawned, took a sip of the iced tea in his hand, and then leaned lazily on the wooden chair.

"Alas, this ghost place is getting hotter and hotter, and the sect doesn't know how to be considerate and considerate of us, and build a cooling array." The short-haired disciple ticked.

Danxia Peak is not natural, but the Jindan Patriarch inside the gate built it with great mana.

There is not only a second-order spiritual vein located underground, but it is also connected to the earth and fire, and it is even rumored that the depths of the lava are the birthplace of the sect's fundamental spirit plant [Ember Wood].

All kinds of reasons add up, which makes this place very hot, and the disciples stationed there can be said to be very difficult, if it weren't for the high pay, there really aren't many people willing to come here.

There is no way, after all, the environment is harsh and can be endured, but the poor can't bear it.

"But then again, why is it that so few senior brothers come to alchemy during this time?" The short-haired disciple was a little puzzled.

"Open an alchemy room for me."

"Who?!"

The sudden sound frightened the short-haired disciple and jumped up directly from his chair.

"It's me." He followed the voice, and saw a young man standing in front of him at some point.

He was dressed in a simple white robe, with only a simple green wood hairpin on his head, wide robe and large sleeves, and he was not stained with dust, and his temperament was indescribably calm and quiet.

The short-haired disciple couldn't help but be stunned before he reacted, and asked incoherently, "You, why don't you have a sound when you walk?" ”

Lin Chen was stunned by this question for a moment, and then smiled to himself: "Get used to it." ”

Except in the laboratory or in his own home, Lin Chen has always been accustomed to walking silently in the outside world, especially when he is close to people, he not only walks silently, but even unconsciously hides in the blind spot of the other party's sight.

Of course, this is just to better protect himself, whether the person who was attacked believes it or not, he thinks so anyway.

"I'm going to open an alchemy room." Lin Chen continued.

"Good, good!" The short-haired disciple nodded hurriedly.

"Wait, are you Senior Brother Lin from the Outer Gate?" When recording the information, the short-haired disciple reacted with hindsight and said in surprise.

"Oh? Do you know me? ”

"Of course, the spirit bullet technique that Senior Brother performed on the Outer Gate Dabi is too handsome, much more handsome than those barbarians who can only use their hands, and the guys who don't have the brains to use spirit weapons to beat people!" The short-haired disciple said with a look of adoration.

"I didn't expect me to have fans...... Lin Chen smiled slightly and nodded.

"Senior brother, what do you think of this earth fire room? Not only is the fire qi sufficient, but the location is not directly facing the fire vein outlet, and the spiritual fire is relatively stable, easier to control, and easy to alchemy. The short-haired disciple asked reverently.

"Huh?" Lin Chen glanced at it, looking a little surprised.

This kind of alchemy room is often booked in advance, but I didn't expect the other party to dispatch it to give it to me.

'Is my charisma so great?' This thought flashed through Lin Chen's heart.

Then he smiled and nodded: "I have a heart." ”

"Senior brother is polite, senior brother hereby wishes senior brother success in alchemy."

After speaking, Lin Chen turned around and walked towards the alchemy room under the gaze of the short-haired disciple.

What he didn't know was how many monks of his generation had attracted him to his fighting art in the Outer Gate.

But even if he knew, Lin Chen wouldn't care, the outside world's evaluation was like a breeze blowing on his face, and he wouldn't care.

Creak!

As the door opened, Lin Chen walked into the alchemy room.

The room was very empty, only a huge alchemy furnace was placed in the center, and on the ground was a prohibition with flashing spiritual light, and there was a small pit directly below the Dan furnace, and there was a faint fire shining.

"Let's get started." Lin Chen observed the surroundings, and then directly activated the formation.

Under Lin Chen's control, the earth fire instantly rose upward, and the entire Dan furnace quickly became fiery red, and layers of heat waves rolled out in the air!

Lin Chen took out Chaoxia Yunzhi, threw it into the Dan furnace, and then took out various auxiliary medicines such as spiritual liquid and chalcedony, and threw them directly into the fire.

This situation will definitely make most alchemists think it is a joke when they look at the jumping beam clown.

Alchemy pays attention to the amount of medicinal materials, when to enter the medicine, and what is the heat? This kind of crude refining medicine will only waste the best spiritual materials in the end.

But in Lin Chen's opinion, this kind of guy who spends a lot of materials to try and summarize the appropriate heat change method can only be regarded as a craftsman, and he hasn't even touched the threshold of Dandao!

Alchemy, alchemy, is to extract the medicinal properties of the elixir and condense it into a pill.

Blindly pursuing the geometry of the amount of medicinal materials, how hot it is, rather than the content of medicinal properties, this practice is completely contrary and contrary!

For example, how are the medicinal properties of nine-year-old ginseng and ten-year-old ginseng the same? What is the weight of the Juyuan flower that grows in the place where the aura is full and the aura that grows in barrenness? How should the elixir grown by abundant rain and drought be adjusted in the heat to remove excess water?

When the brainless craftsman saw that the alchemy master put in the medicinal materials and adjusted the fire, he thought that he had mastered the trick, and he paid attention to the fact that every bit should correspond to the master's standards, but he didn't know that this was the best choice made according to the changes in medicinal properties!

"The way of alchemy is broad and profound, I don't understand. But there is one thing I understand, the essence of alchemy is to extract the medicinal properties that are easy for the human body to refine through various means, and eliminate those that are not easy to refine! ”

Medicinal properties are the manifestation of the aura of various attributes of heaven and earth in the elixir.

Although there are many kinds of spiritual roots in the human body, the body is made of water and eats wood for a living, so if monks want to refine the spiritual energy of different attributes, they often swallow the elixir of the corresponding attributes, rather than directly swallowing magma, gold and iron.

However, among the elixirs, even if they are elixirs with corresponding attributes, such as Huo Yuanzhi and the like, they are likely to have other medicinal properties such as feminine and earthy properties due to environmental factors, and these other attributes that do not meet the medicinal properties required by the monks are collectively called impurities.

The alchemist is the medicinal extraction required by the monks, and if it is not extracted, it will remain in the human body, forming the so-called erysipelas, which will affect the progress of cultivation.

Based on this theory, even if Lin Chen didn't understand the four principles of Dan Dao's 'yin and yang', 'lifting', 'turbidity' and 'movement and static', he also understood a key point, so many changes in alchemy, in the final analysis, is to extract the substances that the monks need.

When it comes to the extraction of matter, Lin Chen's first reaction is the chemistry he learned in high school in his previous life!

"The change of medicinal properties lies in yin and yang, not only yin and yang medicinal properties, but the combination of one thing and one thing, and the exchange of one thing and one thing into two things; Even one thing and one thing, and then with the participation of the third thing, one thing is synthesized, or two things are exchanged, and the third thing remains the same......" Lin Chen silently recited the exposition of the De Dan Dao recorded by the ancients found from the Tibetan Scripture Pavilion, and his eyes gradually brightened.

It's so complicated, but in the final analysis, isn't it similar to the decomposition reaction, chemical reaction, displacement reaction, etc. in chemistry in the previous life?

It's just that the particles are replaced with aura, and the means and methods of extraction are changed, but the fundamental theory is similar!

And with the spiritual sense of the foundation building period, Lin Chen could discern the medicinal properties in it, which also provided the possibility of success in his experiment with the non-poisonous gas pill!

"In my opinion, the first step in alchemy is to use the method of fire refining to decompose complex medicinal properties!"

Whoosh~

The tongue of fire continued to lick the spiritual materials and Yunzhi in the Dan furnace, causing them to gradually melt into a medicinal liquid mixed with various spiritual energy.

Lin Chen controlled the spiritual flame in the furnace fire, smelting the medicinal liquid, under the double refining of true qi and flame, the various medicinal properties mixed in the original medicinal liquid began to decompose, and the already inert spiritual energy sank to the bottom of the Danding, and the active spiritual energy that could be refined by the monks rose to the upper Dan room.

This phenomenon is also known as the rise of clear qi and the fall of turbidity in Danfang!

"The second step is to extract the medicinal properties that the monk needs by refining with water!"

Lin Chen's spiritual root is water, fire, and earth, and what is needed is the medicinal properties of the corresponding attributes, and the rest of the medicinal properties not only cannot increase Lin Chen's cultivation, but will form erysipelas in his body to affect the advancement.

And if he wanted to extract this spiritual liquid containing complex medicinal properties out of what he needed, Lin Chen's first reaction was to extract it with water!

The Dan Qi slowly rose under Lin Chen's control, and after it came into contact with the Clear Ice Stone, it condensed when it was cold, turning into Dan liquid and dripping down along the hole.

Lin Chen collected it and used several methods of extracting medicinal properties such as melting, refining, and chemical to extract the three medicinal properties of water, fire, and earth in the medicinal liquid!

"The third step is to use the method of earth refining to mix medicinal properties!"

Lin Chen was not a single spiritual root cultivator, if he simply absorbed one kind of spiritual energy to cultivate, it would lead to an imbalance of true qi in his body, so he had to mix the medicinal properties of the three attributes!

Between thoughts, Lin Chen took out a culture medium, but the soil inside was not brown, but bright red like blood, this was the medium made by Lin Chen from his own flesh and blood.

Lin Chen stretched out his hand and made a move, and the three medicinal liquids flew out separately, mixed into one, and flew directly into the blood soil under the wrapping of a spiritual light.

"The fourth step is to use the method of wood refining to condense into Dan!"

Lin Chen took out a dry and lifeless spirit plant branch, injected his true qi into it, and then directly inserted it into the blood soil.

It didn't take long for the dead branches to emerge as if they were rejuvenating, and then they directly absorbed the blood from the soil and grew rapidly.

In just a few moments, a lush green plant was formed, and in an instant, flowering and breeding, it actually produced elixirs the size of dragon's eyes!

The peculiar thing is that these elixirs seem to be entities, but if you look closely, they seem a little illusory, obviously, this is not an actual elixir, but a wisp of condensed and formed, without any impurities!

No Poison Pill!

And this Qi Pill absorbs Lin Chen's blood to grow, and it is itself contaminated with Lin Chen's breath, so he doesn't even need to refine, he can increase his cultivation by swallowing it directly!

"The fifth step, use the method of gold refining to save the pill!"

Lin Chen took out a spirit jade, and gently touched it to the green plant, and the pills on it fell one after another, turning into wisps of gas and flying into the jade, forming a spirit pill that emitted a faint blue light.

Using the method of gold and jade spirit stones to store the pill, not only can it be stored for a long time, and even put it into the spiritual vein, but it can also continuously assimilate the same kind of spiritual energy, and after placing it for hundreds of years, take it out, and take it so that a monk who has just cultivated can complete the cultivation of the qi refining period!

"The way of alchemy is to extract and preserve the required medicinal properties, as long as you can do it to this point, why stick to fire alchemy!"

"Using the method of the five elements to refine the pill and store the pill, remove impurities, and preserve its essence, this is the way of cultivating the elixir that belongs to me!"

Seeing the illusory Qi Pill in his hand, Lin Chen's face showed a touch of joy.

He had been studying for so many years, and finally completed the experiment of the [Non-Poisonous Gas Pill] with the help of Lingjue!

From now on, one more obstacle will be removed from the long and obstructive path of cultivation, which will allow him to move towards a more distant future!
