Lu Xu, who returned to the practice room of the mansion again, sat down cross-legged and took out a transparent box from the storage bag, which contained the cluster of green lotus-shaped flames, the size of a fist.

Lu Xu looked at the flames not far away, and didn't dare to open the lid of the box, he knew that once he opened it, he was afraid that the high temperature it emitted would directly incinerate him into nothingness.

The power of this spiritual fire is not ordinarily powerful, it is said that as long as the monk of the Yuan Infant Stage is contaminated with a trace, his soul will be destroyed. What's more, he is a monk in the foundation building period, and I am afraid that as long as he gets closer, he will be melted.

This spiritual fire is very famous in the immortal cultivation world, and there are only two or three of them in the present world from ancient times to the present, but the appearance of each spiritual fire has caused a bloody storm in the immortal cultivation world.

It's just that Lu Xu couldn't figure out that the green-haired iron corpse had been getting the spiritual fire for so long, and he hadn't refined this thing. Although the spiritual fire is powerful, with the help of some magic circles and special materials, there is still a chance that it can be refined.

However, it is fortunate that this green-haired iron corpse did not refine this fire, otherwise there would really be nothing to do with Lu Xu.

Lu Xu suddenly slapped the storage bag in his hand, and a giant tripod several feet large appeared in front of him, and he found it in the underground hall that day, this big tripod seemed to be specially made for placing spiritual fire refining, which could isolate the temperature of spiritual fire.

The translucent box was put into the big tripod by Lu Xu, and then Lu Xu pinched the trick with one hand to open the lid of the translucent box, and the next moment, with a "poof" sound, a burst of blazing high temperature rushed towards him.

A flash of cold light.

Lu Xu flipped his other hand, pulled out a high-grade short knife magic weapon, and slashed at the spiritual fire.

After a "poof", the short knife flashed a burst of brilliance as soon as it approached the spiritual fire, and then it was incinerated into nothingness like a piece of paper.

Seeing this, Lu Xu was shocked, pondered for a while, and then patted the storage bag, and took out a jade slip from it, which recorded a secret technique of extracting the energy of spiritual fire and refining it into fire.

After a long while, Lu Xucai's eyes narrowed, and after looking up at the green lotus-like flames beating in the ding, a trace of complexity suddenly appeared on his face.

"Qinglian Karma Fire! I didn't expect the Qinglian Karma Fire, which ranked eleventh on the Spirit Fire List, to be obtained by me. ”

Through the record in this jade slip, Lu Xu finally knew that this cluster of green lotus-shaped spiritual fire turned out to be the famous green lotus karmic fire on the spiritual fire list.

And now Lu Xu finally understood why the green-haired iron corpse didn't refine this spiritual fire, not because he didn't want to, but because he had no way to refine it at all.

Qinglian karmic fire, also known as the spiritual fire to ward off evil spirits, has the special effect of purifying all things. Any thing that is touched by evil spirits and demons will be purified into nothingness as long as it is stained with a little bit. Even this kind of spiritual fire can kill the demons in the heart, and all evils will not invade, and it has a miraculous effect on assisting the cultivation of monks, and the power is extremely terrifying. This kind of spiritual fire is extremely rare in heaven and earth, and there is only one flower, but no one knows where it is.

The green-haired iron corpse does not say that it is refining the Qinglian karma fire, if it is not isolated from the Great Ding with a translucent box, I am afraid that as soon as it gets close to the surrounding area of it, it will be purified into nothingness. Presumably, the green-haired iron corpse also knew about this situation, so he deliberately created such a big tripod for extracting the energy cultivation fire of the spiritual fire. In fact, the cyan fire of the green-haired iron corpse had nothing to do with the Qinglian karmic fire, because Lu Xu did not feel a trace of purifying magic power on it, so it was more appropriate to call it corpse fire. I don't know how this green-haired iron corpse used to remove the purifying elements in those flame energies, maybe that's why he can drive only a trace of flames. If it is allowed to extract the energy of the Qinglian karmic fire and refine it into fire without any scruples, I am afraid that ten Lu Xu will die.

Although Lu Xu has obtained this Qinglian karmic fire, he has no way to take it now, only when he reaches the Jindan stage or even the Yuan Infant stage, he may have the opportunity to refine it with the help of foreign objects.

In the next two days, Lu Xu deliberately took the Transformation Pill to change his face and went to the shop in Fang City a few times, and began to look for some classics related to Qinglian Karmic Fire, so as to determine the characteristics of Qinglian Karmic Fire, as well as find some materials for restrained flames.

After Lu Xu finished searching the classics related to Qinglian Karma Fire, he immediately spent tens of thousands of spirit stones to purchase a batch of auxiliary materials, and then went to the alchemy room to refine a few auxiliary pills, and immediately began to retreat in the mansion.

Although it is absolutely impossible for him to refine the Qinglian Karmic Fire with his current cultivation, it is still possible to extract the energy of the Qinglian Karmic Fire like that green-haired iron corpse and cultivate, although its power may only be less than one in one hundred thousand.

Half a month later, Lu Xu, who was in the practice room, sat on a futon with a pale face, and a pale golden magic circle was inscribed on the ground with it as the center, and more than a dozen middle-level spirit stones of different sizes were inserted throughout the circle.

Lu Xu's eyes were closed, and there was a big tripod suspended in front of him.

And there was a cluster of green lotus-like flames faintly inside the big ding, and above it, a small green lotus-shaped firework with a trace of cyan on the surface was slightly beating and uncertain with Lu Xu's technique. It was the trace of Qinglian Fireworks energy that Lu Xu had spent half a month extracting, which contained a tiny trace of purifying magical powers. As for directly extracting a trace of Qinglian Karma Fire for refining, Lu Xu would never dare.

As time passed, Lu Xu's face gradually regained some ruddy color, and then his eyes opened, and he opened his mouth to spew out a cloud of essence blood.

With a "bang", the essence blood burst open in an instant, turning into a cloud of blood mist and enveloping the small green lotus-like flame inside.

In the entire practice room, there was a lot of blood for a while. At this time, Lu Xu suddenly pinched the trick with one hand, and the magic circle on the ground suddenly lit up, and golden runes appeared.

At the same time, the blood mist swirled around the green lotus-like flames, and then disappeared without a trace.

In the pale golden light, more than a dozen new blood marks suddenly appeared on the surface of the blue lotus-like flame, and the other blood marks vaguely formed a very complex pattern.

At the moment when the entire blood-colored array was formed, the green lotus-like flame shone brightly, and circled and flew up and down around Lu Xu with a buzzing sound.

The blue lotus-like flame, which was originally stationary, seemed to come to life all of a sudden.

"It's finished"

Seeing this, Lu Xu's spirits were greatly lifted.

The next moment, he didn't have any spells, and the green lotus-like flame "swished" and slowly approached it.

"Poof"!

The blue lotus-like flame suddenly turned into a cyan flame-like existence, and after a roll, it was only a few zhang away from Lu Xu.

"Ah" screamed in pain, as soon as the flames approached, Lu Xu felt a scorching heat, the skin on his body tingled, his brows furrowed, and his body trembled slightly.

Lu Xu hurriedly curled his palm slightly, and a small jade bottle was sucked into the palm of his hand, tilting the jade bottle, the size of a dragon's eye, faintly revealing a little luster, rolling the round pill into his hand.

This is a Blood Yuan Pill, which Lu Xu specially prepared for refining the energy of Qinglian Karmic Fire, he put it under his nose and sniffed it lightly, a strange smell, lingering on the tip of his nose, that kind of cold feeling, made people's spirits shocked.

Keeping his eyes firmly fixed on this elixir, Lu Xu's fists clenched suddenly, then closed his eyes and stuffed one of them into his mouth.

As soon as the Blood Yuan Pill entered his mouth, it turned into a slightly cold energy, quickly penetrating into the meridians in Lu Xu's body, and finally like layers of blood film, it slowly penetrated into the meridians and bones.

With the penetration of the blood film, Lu Xu's body suddenly trembled violently, and a trace of blood kept rising out of the pores, just in the blink of an eye, Lu Xu's body seemed to be coated with a layer of red blood, which looked extremely terrifying.

Soon after the blood appeared, it was rapidly condensed by the cyan flames that gradually approached Lu Xu, and finally formed a blood-colored cuticle, which not only wrapped Lu Xu's hands and feet, but also his eyes, were completely enclosed in it.

The blood-colored cuticle seemed to be constructed into a set of impermeable blood-colored armor, which protected Lu Xu strictly in it, protecting him from being burned to death by the cyan flame.

Slowly stretching out his palm wrapped in the blood-colored stratum corneum, Lu Xu pinched the tricks in his hand again and again, one after another, and rushed out towards the cyan flames.

With the entry of the magic technique, the cyan flame that slowly approached Lu Xu's body suddenly jumped, and in the blink of an eye, a terrifying destructive power slowly expanded out of the cyan flame as if it had awakened.

Staring at the increasingly huge cyan flames in front of him, Lu Xu knew that the most critical moment was coming.

In the bright practice room, the cyan flames were churning violently, and with the clusters of flames burning, the space around the flames obviously showed some conspicuous traces of distortion, but I didn't expect that the meaning energy of the Qinglian karmic fire was so terrifying.

In mid-air, the cyan flame rose against the storm, and in the blink of an eye, it expanded its own volume by nearly a hundred times, and with the change of its volume, the originally docile flame also became violent, and the flames whirred and churned, making a sneering sound, and the surrounding air was also burned into nothingness by the blazing green fire. Fortunately, Lu Xu had already arranged the Heavenly Gate Golden Lock Array in the courtyard of the mansion to cover it, otherwise such a big movement would definitely attract the attention of other monks.

Looking at the huge green fire in mid-air, Lu Xu took a deep breath of hot air with a solemn face, and the palm covered by the blood-colored cuticle was aimed at the green fire from afar, and then pinched again and again.

As one spell after another entered, the cyan flames moved slowly, and each spell could only last for two or three seconds before being incinerated into nothingness by its terrifyingly hot temperature.

Therefore, although the distance between Lu Xu and the cyan flame was only a few meters, the mana consumed in it was extremely huge.

His eyes were firmly fixed on the cyan flame that slowly moved over, Lu Xu's breathing was slightly short, and his forehead was covered with sweat, and the sweat flowed down his cheeks, under the reflection of the blood-colored protective film, it was like a drop of red blood.

As the cyan flames gradually approached, the terrifying heat emitted from it made Lu Xu's face show a trace of horror. This is the eleventh place on the spiritual fire list, and it is just a trace of its energy, which is so terrifying. If it had been allowed to refine a wisp of flame, I am afraid that it would have been incinerated into nothingness long ago, and if it was delusional to refine the entire Qinglian Karma Fire, then it would really not have died if it had not died.

When the huge cyan flame stayed about a meter in front of Lu Xu, even though the interior of the mansion had been isolated by the confinement power of the Heavenly Gate Golden Lock Array, the terrifying high temperature it emitted still caused some of the hard masonry inside the practice room to gradually burst apart. After a few moments, the walls of the practice room were reduced to small pieces of rubble, and the rubble was burned into piles of fine powder.

And at this moment, Lu Xu, who was frowning, suddenly raised his head, stared at the cyan flame that was getting closer and closer, and slightly trembled with his palm slightly opened and closed, and made several strange magic seals in a row.

I saw that a small wisp of green lotus-like flame gradually peeled off from the huge flame, and then it slammed into Lu Xu and entered his body in an instant.

The green lotus-like flames entered his body, Lu Xu immediately frowned, and at the same time, his whole body trembled violently as if he had been struck by lightning, and his face, which was still a little bloody, suddenly turned pale.

Forcibly enduring the scorching pain coming from his body, Lu Xu's eyes slowly closed, and his divine consciousness gradually sank into his body.

The divine consciousness sank into the body, and suddenly, a misty sensory interface appeared in Lu Xu's heart, at this time, within the many meridians in the body, the green lotus-like flames that entered it had been differentiated into wisps of tiny cyan flames, these cyan flames containing terrifying energy, shuttling indiscriminately among the meridians, and everything that was blocked in front of him would be incinerated into nothingness by them in an instant.

With the shuttle of these cyan flames, although Lu Xu's meridians were protected by the blood film condensed by the Blood Yuan Pill, the terrifying high temperature still slowly penetrated into it, although the residual temperature of these infiltrations was not so hot, but for the most fragile meridians of the human body, it was undoubtedly a devastating blow......

Under the smoke of these high temperatures, the originally spacious and tough veins have been twisted like twisted flowers, looking extremely strange and terrifying.

Of course, the meridians were so twisted that the pain caused by it directly made Lu Xu's body cramp indirectly, the muscles all over his body were tense, and the green tendons like earthworms were constantly stirring, and his pale face was not the slightest blood. This is the consequence of not being able to reach the realm, if Lu Xu is now a Jindan stage monk, he will definitely not be so painful.

In the meridians, the cyan flames shuttled wildly, and in just a few minutes, Lu Xu's body was almost destroyed, and the worst thing was that the medicinal power of the Blood Yuan Pill was already being volatilized in the consumption of the flames, and those dissipated blood films no longer had enough medicinal power to support them to repair.

Under the premise of having the protection of the blood film, Lu Xu's body is still in such an almost crippled state by the terrifying flames, if the blood film disappears, all the things in Lu Xu's body, meridians, bones, heart, etc., will almost be incinerated into nothingness by the green lotus-like flames in a very short period of time. And when the time comes, without these vital organs that sustain life, Lu Xu, even if he is a monk in the foundation building period, has only one way to die.
