Opening the fire gate, a thick flame burst out of the ground with a bang, enveloping the entire alchemy furnace.

"It's worthy of a fourth-level alchemy room, what a thick flame!"

Liu Wuxian said secretly, no wonder the third-level alchemy room could not refine the fourth-grade pill, all of which were inextricably linked to the flames.

The higher the level of the elixir, the more demanding the flame is, and Liu Wuxian did not awaken the fire element, so he could only rely on the core flame to refine it.

There was no hurry to refine the four-grade pill, first start with the Yuanyang Dan, familiarize yourself with the technique, let the Dan furnace preheat, and then refine the bone refining pill.

Time passed minute by minute, Yuanyang Dan was familiar with the road, and in just one hour, four or five furnaces were refined, and the ground was full of porcelain bottles, which contained thousands of Yuanyang Dan.

At this moment, the Imperial Academy is busy with the New Year's party, whether it is Tianzi, Xuanzi, or Dizi, all students have been on vacation and can move freely.

The annual gathering is very huge, not only all the students have to participate, but even some instructors will also show up to exchange the learning results of the year.

Liu Wuxian was silent in the refining of medicine, looking at the Yuanyang Pill in a furnace, and he was in a very good mood.

Each medicinal material, after the transformation of the mysterious seedlings of the Taihuang Dantian, the quality of the elixir has been greatly improved, and the refined elixir has better medicinal effect.

After refining more than 30 furnaces, the Dan furnace was completely heated, and it was possible to refine the four-grade pill.

About half of the medicinal materials on the elixir shelf were consumed, and with a sweep of his palm, the flames suddenly soared, and the intense temperature made the alchemy room extremely hot.

Liu Wuxian took off his coat, leaving only a piece of underwear, and his hands formed strange marks.

Bone Refining Pill!

As the name suggests, it has the effect of tempering bones, which can strengthen the body and make the bones stronger.

Especially sword cultivators, they like to cultivate into sword bones, and every inch of bone in their body is used as a divine weapon to cultivate.

Liu Wuxian uses a short knife, the requirements for bones are more demanding, and the stronger the bones, the smoother the knife technique will be.

Refining Pill!

Tempering the bone marrow in the human body and washing the essence of the marrow realm is to wash the essence and change the marrow, and be reborn.

Soul Refining Pill!

Tempering the soul power in the soul sea is many times higher than the Soul Gathering Pill, and the Great Yan Dynasty does not know about this kind of pill, this is Liu Wuxie's broadening from other pills.

These three elixirs could not directly allow Liu Wuxian to break through the Soul Washing Realm, the main purpose was to accumulate the foundation.

He cultivated the Heavenly Swallowing Technique, and he had the Heaven Swallowing God Ding, and the resources he needed were dozens of times that of ordinary people.

These pills can lay a good foundation in advance, accumulate enough strength, and break through the realm in one fell swoop.

Liu Wuxian could refine a lot of pills that quickly improved the realm, but he didn't do so, relying on the pills to improve the realm, there were many disadvantages in the later stage, just like Xue Baisheng, it was useless.

Impacting the Spirit Washing Realm, one Chong Ling Pill is enough, but as a result, the foundation will be unstable, and the cultivation speed will slow down in the future.

The pill is only an auxiliary, and you have to rely on yourself to cultivate.

The main purpose of these elixirs is to temper the tibia, wash the marrow and remove the hair, and improve the soul.

The first step is to refine the Bone Refining Pill!

Using various rare demon beast bones such as tiger bones and earth dragon bones, extract the essence of their bones, and use them with elixirs to refine them into pills.

The Bone Refining Pill rewarded by the academy was so ineffective that Liu Wuxian swallowed it, and the effect was minimal.

Although it was a deleted version of the Bone Refining Pill, Liu Wuxian didn't dare to be careless, and the Four Pins Pill could not tolerate any differences.

The Innate Realm refines the four-grade pill, if this is spread out, I'm afraid no one will believe it.

The flames whirred, enveloping the entire alchemy furnace, and the first tiger bone was thrown into it, making a sizzling sound, and the tiger bone was rapidly melting, turning into drops of golden liquid, flowing in the Dan furnace.

One after another, more and more hard bones were thrown into the alchemy furnace and fused with the tiger bones.

A few rare four-grade elixirs were thrown into the alchemy furnace, and those dissolved liquids emitted a restless breath and repelled each other.

The seal of both hands, Liu Wuxie's alchemy, does not rely on the realm, but on his techniques.

There is no one here, Liu Wuxian is not afraid to leak the alchemy technique, and all kinds of rare handprints form countless spiritual patterns, floating around the alchemy furnace and blending into it.

In the alchemy furnace, there was a large basin of liquid, rising and falling, emitting all kinds of strange roars.

These bones contain the memories of those demon beasts before they were alive, and they were tragically refined, stimulating the ferocity of the beasts, and they wanted to break free.

"Hmph, I've been dead for so long, and I still want to break free!"

His hands suddenly pressed down, and two yin and yang fish patterns appeared, covering the sky above the Dan furnace, and those roars were gone.

Continuing to refine, the core flame became stronger and stronger, and the liquid inside began to solidify, developing towards the form of an elixir.

An hour passed, and there was a slight collision sound in the Dan furnace, like beads, hitting each other, and each bone refining pill seemed to be only the size of a soybean, but it was extremely heavy.

As time passed, the sound of the impact coming from inside the Dan furnace became more and more intense.

Like thunder and tiger roaring, the Dan furnace shook from side to side, and the grade of these bone refining pills was very high.

"Put on fire!"

The palm of his hand slashed horizontally, and the yin-yang fish covering the Dan furnace disappeared, and a cloud of misty qi transformed into a fierce tiger form, and pounced on Liu Wuxie.

The spirituality of these bone refining pills is extremely strong, and through small imprints, they can actually transform into a thousand forms.

Liu Wuxian blew a breath, and the fierce tiger that pounced suddenly disappeared, all of them turned into air, and then there was a rich danxiang, which filled the entire alchemy room.

Looking towards the inside of the Dan furnace, there were twelve bone refining pills, neatly placed together, and each pill was covered with Dan patterns.

"Good Dan!"

Take out the porcelain vase and put them all in it, rest for an hour, and continue refining.

Take out a large amount of Yuanyang Dan and swallow it to replenish the consumption of true qi.

After the spirit recovered, he began to refine the Essence Refining Pill.

At this moment, most of the days had passed outside, and Liu Wuxian planned to finish refining in two days, and the remaining three days of retreat and cultivation.

The Essence Refining Pill is different from the Bone Refining Pill, which needs to be refined by simmering, and the requirements for flames are more demanding.

One fierce fire refines, a small heat slowly boils.

Take out a few porcelain bottles from the storage bag, pour out some red liquid, and flow into the alchemy furnace.

This is not the bone marrow of a demon beast, but a liquid extracted from an elixir.

Pick up ten elixirs and throw them in, and start boiling.

Refining the Marrow Refining Pill was in a hurry, holding a pu fan in his right hand, gently fanning the flames, every step was extremely slow.

While refining the marrow cleansing pill, he was running the Heavenly Swallowing Technique, and the rich aura penetrated along the flame channel.

This flame passage went straight to the Yanyang Cave, and the earth-shattering scorching sun qi covered the entire alchemy room.

In just a few breaths, a faint layer of spiritual rain formed above the alchemy room.

Although it is not as good as Yanyang Cave, it is much better than the environment outside, and it does not waste any time in cultivation.

Take out a bone refining pill and swallow it in one gulp.

It was like the weight of a thousand catties, the moment the Bone Refining Pill entered the stomach, it was like eating a piece of lead, and the stomach made a gurgling sound and suddenly fell.

The pill entered the abdomen and dissolved in an instant, forming a monstrous energy that rushed into the limbs and hundreds of remains.

Every inch of bone, as if wrapped in flames, was calcined like crazy.

The pain of drilling his heart made Liu Wuxian let out a miserable cry, gritted his teeth, and didn't let himself shout.

His limbs and bones became extremely stiff, and he couldn't move for a while, and the energy in the bone refining pill turned into knives one after another, falling on the bones of his body, gently scraping and scraping.

Every time he scraped down, Liu Wuxie's body trembled, and he finally understood what it meant to scrape bones and heal injuries.

He didn't scrape one place, but the whole body.

The dirt covering the surface of the bone is removed, and the remaining energy penetrates down the bone.

In the next scene, Liu Wuxian was a little incomprehensible, and some inexplicable lines appeared on the bones.

He hadn't seen these lines before, they were very strange, and they should have a lot to do with the Bone Refining Pill.

"The medicinal effects of these bone refining pills are far beyond my expectations!"

He could only comfort himself in this way, and with the blessing of these lines, Liu Wuxian found that his bone strength had greatly increased, far beyond ordinary people.

The body regained its freedom and continued to fan the flames, and it would take some time for the Refining Pill to come out.

Another bone refining pill was swallowed, and the effect of this time was far inferior to the previous one.

If you swallow too much of each pill, the efficacy will be greatly reduced.

Xuanzi area!

In a delicate courtyard, there was a sudden sound of various porcelain smashing on the ground.

"I'm!"

Ji Yang's cloak was scattered, and his appearance looked terrifying.

He came back with the corpses of the two entourage, and found the dean's comment, and said that they made the first move, according to the rules of the academy, knowing that the other party was a four-star alchemist, he also rashly made a move, violating the rules of the academy, even if he was killed, he deserved it.

Ji Yang never imagined that the dean would already know that Liu Wuxian had become a four-star alchemist.

Originally, he planned to use the dean's hand to deal with Liu Wuxie, but this path was impassable.

The corpse was placed in the courtyard, he was a four-star alchemist, and he was the only one living in the entire courtyard.

"Liu Wuxie, you wait for me, I will kill you with my own hands!"

Ji Yang said it almost word by word, and a flame condensed in his eyes, and reason was telling him that he couldn't mess up now, and he would first find a way to refine the four-grade pill.

"Danbao Pavilion, that's right, I'll go to Danbao Pavilion now, they have a four-star alchemy room. ”

Hurried overnight, leaving the Imperial Academy and heading to Danbao Pavilion.

He forcibly broke through the realm, but the sequelae were not cleared in time, and he basically cut off his cultivation career.

Liu Wuxian was completely unaware of all this, and was silent in alchemy.

For a day and a night, Liu Wuxian almost never sleeped, and the Refining Pill had already taken shape, exuding a rich Dan fragrance.

"Faster than I expected!"

Standing up, his hands began to seal, and he entered the Ning Dan stage.

The Bone Refining Pill was completely different, there was not a single sound, the entire Alchemy Furnace was quiet, and the flames were slowly dissipating.

Isn't it that the air is filled with a strong Dan incense, thinking that the Dan furnace is empty.

Closing the fire gate, the terrifying ice true qi enveloped the alchemy furnace, cooling it down instantly.

Looking inside, a full ten Refining Pills were lying quietly in the Dan Furnace, exuding an alluring dark purple luster.

Take out an empty porcelain bottle, put away the ten Soul Refining Pills, and continue refining the Soul Refining Pill.

Time was pressing, so I only rested for half an hour and devoted myself to alchemy.

All the remaining medicinal materials were taken out, and the fire gate was opened, and the fierce flames rose more than a meter high.
