Nine Yin Grass, refined.

　　Earth Dragon Root, refining complete.

　　Yanwei Zi, refining completed.

　　......

　　There were more than thirty kinds of herbs, and it took Long Chen several whole hours to refine them one by one, and he was tired and sweating profusely.

　　Refining was not the same as boiling medicine, it required refining the essence of each herb, removing the impurities from it, and then refining it into powder.

　　However, the fire in Long Chen's hand was too trashy, and the refined powder had too many impurities, but it couldn't be helped.

　　Firstly, Long Chen's cultivation level was not enough, there was no sustained energy to stimulate the Dan fire, so the power of the flame was not strong.

　　Secondly, Long Chen didn't have the opportunity or ability to tame other flames right now, so he could only make do with what he had.

　　The Wind Mansion Dan, was a first-order elixir, and usually a Dan cultivator whose realm had reached at least the Dan Apprentice level could only refine a first-order elixir.

　　However, if one wanted to practice the art of refining pills, in addition to having a powerful pills fire, one needed to match it with a majestic spiritual qi, and most importantly, one needed an extremely powerful soul force.

　　The other two are not difficult, Dan fire as long as there are conditions, you can capture fire magical beasts, tamed into pets, with the help of magical beasts of fire, cultivate their own fire, as very powerful.

　　Ninety-nine percent more than the alchemist, with the beast fire, only some of the inheritance is extremely old, with a strong strength of the alchemist, to control an extremely mysterious and ethereal spirit fire between heaven and earth.

　　Spirit fire is a kind of flame with a soul, in Long Chen's memory, it seems that he had once mastered a kind of extremely awesome heaven and earth spirit fire.

　　Unfortunately, even if it was bullish, it now had to use a wasteful trash fire to continue refining pills, and it was impossible to take out what was in his memory.

　　Resting almost, Long Chen took a deep breath.

　　"Whew."

　　A half-foot-long waxy yellow flame jumped out of the palm of his hand, and a wave of heat surged through him.

　　"It's not bad, after the refining just now, the power of the flame, slightly longer a trace, forget it, it's better than nothing"

　　Continuously putting the seven drug essences, into the furnace, the power of the soul unfolded, and the flame in Long Chen's hand suddenly pulsed, several times more powerful than before.

　　"Using soul force to catalyze the flame, if another alchemist saw it, would they be scared to death?" Long Chen burst into a bitter laugh.

　　The most valuable thing an alchemist had was soul power, and a person's soul power was basically innate, growing passively as their cultivation level increased.

　　Soul power, is the fundamental alchemy, alchemy, need a lot of soul power, control the fire, a slight error, will lead to the previous work, practiced into a pile of Dan ash, if the potency of the potion is strong, will also blow up the furnace.

　　Usually alchemists, is not in the beginning, on the input soul force, basically in the middle and late, when the elixir is about to be formed, with the soul force to carefully control the output of the fire.

　　After all, at that time, it is the key to the formation of the Dan, the temperature of the flame needs to be constantly changing, sometimes high, sometimes low, sometimes fierce, sometimes slow, for the soul force consumption is very large.

　　If the soul power was depleted at that time, then a furnace of dan, basically even if it was scrapped, and Long Chen actually used the soul power at the beginning.

And the incomparably precious soul power, just to increase the fire, as firewood burning, any alchemist that

would definitely have to break out in curses, even if he was a loser, there was no loser like him.

　　However, Long Chen was not afraid, according to his memories, his soul power nowadays was not inferior to the average alchemist.

A case of content theft: this narrative is not rightfully on Amazon; if you spot it, report the violation.

　　The ranks of Dan cultivators were, in order, Dan Apprentice, Dan Shi, Dan Master, Dan King, Dan Emperor, Dan Zong, Dan Zun, Dan Saint, and Dan Emperor.

　　In Long Chen's memory, he had the memories of a Dan Emperor powerhouse, so he was very clear about his own energy.

　　This time when Long Chen woke up, his soul power had mutated and was unusually powerful, so Long Chen was qualified to do so.

　　"Buzz."

　　The Dan Furnace in front of Long Chen shook slightly and let out a soft sound.

　　"Hehehe, adding fuel to the fire makes it much faster"

　　Hurriedly, he threw three more herbs into the furnace, but at this time, sweat had broken out on Long Chen's forehead.

　　Hastily taking out a stalk of grass more than two feet long, one end of it was put into the medicinal altar, where an altar full of Qi Return Liquid was placed, and the other end was put into his mouth, and he fiercely inhaled a mouthful of it.

　　After the Qi Recovery Liquid entered the abdomen, the pores of his body opened rapidly and began to absorb the spiritual qi of heaven and earth crazily, and the spiritual energy that was originally about to be depleted was recovering rapidly.

This was something that Long Chen had prepared long ago, and it was also the necessary work for refining the Wind Mansion Dan, otherwise with his current little spiritual

power, wanting to refine the Dan could only be a joke.

　　With a grass stalk in his mouth, he sucked in a mouthful of Qi Return Liquid from time to time, supplying the spiritual Qi output in this body.

　　Compared to Long Chen's aura, his soul power was too strong, and it wasn't until two days later that Long Chen felt a hint of fatigue, which was a sign that his soul power was greatly depleted.

　　However, at this time, all the medicinal ingredients in the Dan furnace had already been put in, and all that was left was to finish the job, and the medicinal scent had already started to spread around.

　　Although in Long Chen's impression, a first-order elixir like this could be practiced with his eyes closed, but it was different now, this was something that would change his destiny, and to say that he wasn't nervous would be a lie.

　　"Buzz."

　　Suddenly, there was a throbbing and a buzzing sound within the Dan Furnace, and the aura within the Dan Furnace, began to become furious.

Long Chen did not have a trace of panic, instead, a smile appeared at the corner of his mouth, this was the precursor to the completion of the Dan, and also the most

The most critical moment of alchemy.

　　All of his soul power operated without a trace of reservation, the flame in his hand suddenly skyrocketed, and an invisible force tightly locked the entire Dan furnace.

　　This technique is called "Seal the sky and lock the ground", is Long Chen memory of his own self-created a trick, is to prevent the explosion of the Dan and blow up the furnace used.

　　Moreover, this maneuver was very practical, and could lock all the medicinal power in the furnace in the shortest time, so that not too much would be lost.

　　Usually, alchemists would use it on the last step, as the elixir was raging, and take gentle means to stabilize it.

　　Although doing so, the danger is much smaller, but the loss of drug essence is very large, so the effect of the elixir, very general.

　　"Bang."

　　With the full force of Long Chen's soul force suppressing it, the entire Dan Furnace let out a muffled sound, followed by no sound at all.

　　Long Chen looked at the already calm Dan Furnace in front of him and couldn't help but gasp frantically, his entire body was soaked in sweat, and the whole person also felt the sky spinning.

　　After a while, Long Chen was able to recover slightly, and with excitement, he opened the lid of the furnace, and even his hands were trembling a little.

　　Five rounded pellets were reflected in Long Chen's eyes, and a rich medicinal fragrance filled the entire room.

　　"Two lower grade, three waste pills, alas, say it out, it's going to be a disgrace" Long Chen's face was excited, but his mouth sighed.

　　Long Dust froze and couldn't help but laugh, he had fused the memories of a generation of Dan Emperors, it seemed that that Dan Emperor, was too arrogant.

　　He didn't care about being humiliated, and hurriedly put the five pills into his hands to look at them carefully.

　　Two lower-grade pills, rounded in circumference, with an overflowing, refreshing aroma, the smell of which invigorated the mind.

　　Long Chen couldn't help but feel a burst of ecstasy in his heart, a finished elixir could be sold for at least a hundred thousand gold coins in the Imperial Capital.

　　And the three ruined pills in his hand were also much stronger than the pills his mother had begged for, at least the essence of the medicine, thirty percent of the medicinal power, were locked inside the pills.

The medicinal essence occupies fifty percent of the dan, it is known as the lower grade dan, and the lower grade dan, occupies more than eighty percent of the entire dan

The lower grade elixir, occupies more than eighty percent of the entire elixir world.

　　The medicinal essence that occupies sixty percent is known as a middle grade elixir, seventy percent is known as a top grade, eighty percent is known as an extreme grade, ninety percent is known as an absolute grade, and as for ten percent ...... hehehe.

　　Long Chen would not want to think about it now, it is too far away, maybe some people will think, fifty percent and sixty percent of the medicinal effect, what is the difference?

　　Isn't eating two lower grade pills much better than one middle grade pill? If someone asked this out, they would definitely be spat on.

　　In addition to the essence in the elixir, it is the impurities, the so-called impurities are the things that can't be absorbed by the body, and the most important thing is that those impurities, will cancel out part of the absorption of the essence.

　　The so-called "medicine three poisons" is not a proverb, but a truth, the elixir in the cohesion of the time, will inevitably produce poison, this poison, if not long-term use, will not have too much feeling.

　　But as a practitioner, pills are often life-saving things, a lifetime of not knowing how much to eat, when the body of the Dan Poison cohesion to a certain extent, it becomes a deadly poison.

　　Dan poison is one of the most difficult poisons to remove, penetrating deep into the blood, flesh, bone marrow and even the soul, while the more advanced the elixir, the fewer the side effects.

　　That's why the difference in effect between a lower grade elixir and a middle grade elixir would be more than ten times, while the price difference would be more than a hundred times.

　　Long Chen put away the five pills, packed up the furnace and everything else, could not hold on any longer and fell asleep.

　　I don't know how long he slept, but Long Chen felt a pair of warm hands caressing his cheeks and faintly heard some murmuring sounds, but he was too tired to wake up.

When Long Chen woke up again, it was already three days later, and the hungry man, after wolfing down a meal

started the seclusion again.

　　He swallowed a wasted dan, and with the power of his soul, he guided the power of the dan into the Yongquan acupoint under his feet, where the first star of the Nine Star Overlord Body Technique, the Wind Mansion Star, was coalescing.

　　There was another "bang" sound!

　　Long Chen's right foot shook, and the ground underneath his feet, let out a popping sound as the ground produced cracks that covered the entire room.

　　"Very good, have found the meridian routes and the exact location, next, it's time for the real impact"

　　Long Chen smiled faintly, in his hand, there was an extra lower grade Feng Fu Dan, and directly threw it into his mouth, an extremely pure energy erupted, and under Long Chen's traction, it went straight to the Yongquan acupoint at the bottom of Long Chen's foot.

When the Yongquan Point under his feet moved, it was like a dry riverbed being moisturized, and with the influx of medicinal energy, it was like a scaly dragon that raged wildly there.

　　"Boom."

　　An explosive sound came from the room, terrifying energy overflowed in all directions, Long Chen's body was windless, a terrifying aura exploded, the entire room was shattered, smoke and dust overflowed, and air waves rolled.

　　The smoke and dust slowly dispersed, revealing Long Dust's handsome face, his starry eyes were full of excitement, feeling the soles of his feet, a small bean-shaped body, endless energy surging along his feet into his entire body, Long Dust couldn't wait to raise his voice to the sky.

　　Long Chen's side of the commotion, immediately attracted the attention of the entire marquis, the people have rushed to.

　　Seeing that his mother had also come over, Long Chen hurriedly said, "Mother, today is the day that Shizi enters the Imperial College Palace to study, my hurry over"

　　After saying that, he left behind a group of dumbfounded people and a pile of tattered ruins, changed into clean clothes and headed straight to the Imperial College Palace.
