The next day, Ye Mo came to the teacher's courtyard, hesitated in front of the door for a long time, and finally knocked lightly on the door.

The courtyard door opened automatically, and the young man saw the teacher in the courtyard who was preparing to refine the elixir.

"I've been at the door for so long and I'm afraid to come in?"

Looking at the ridicule in the teacher's eyes, Ye Mo shrugged his shoulders and said helplessly: "No, I just don't know what the teacher is doing, and I'm afraid of disturbing the teacher's practice." ”

"It just so happens that I'm going to refine a four-grade spirit pill, you can watch from the side. Mu Lao waved his hand indifferently.

Hearing this, Ye Mo stood quietly to the side, his eyes carefully swept over several materials on the table in front of Mu Lao, obviously with Ye Mo's current knowledge, he couldn't recognize what these spiritual materials were.

"Xiao Mo, you should know that when refining the spirit pill, the spirit refiner needs an extremely quiet environment, if it is disturbed, the consequences are very serious, I will not suffer any backlash now, but when you refine the spirit pill in the future, you must remember not to be careless, otherwise it is not uncommon to lose your life. Walking to the table, Mu Lao's palm gently touched all kinds of spiritual materials, and his faint tone was slightly stern.

Ye Mo nodded teachably.

Seeing Ye Mo's obedient performance, Mu Lao nodded lightly, his palm spread out, slightly silent, and the dark purple flame slowly rose in his palm.

The soul perception constantly controlled the temperature of the flame, and Mu Lao took advantage of this free time, and after a little hesitation, he said softly: "Spirit refiner, you can generally distinguish his grade from the color of the flame. ”

"For ordinary spirit refiners, the flames are all pale red, and the higher the grade, the darker the color and the stronger the power. ”

Hearing this, Ye Mo blinked, pointed his finger at the flame in Mu Lao's hand, and asked in amazement, "Then teacher's, how can it be purple?"

"Hehe, what I said earlier is a common flame among spirit refiners, but among spirit refiners, in addition to relying on the strength of the aura to trigger flames through the transformation of fire immortals, there is another kind..."Mu Lao smiled slightly, but stopped when he said this, looked at Ye Mo, and asked, "Do you know why people with fire wood immortals can become spirit refiners?"

"Because only people with fire attribute immortals can trigger the flame of refining the spirit pill, but this flame is too violent, if there is no wood attribute spirit qi to protect the spirit material, it is completely impossible to extract the essence of various spirit materials, and naturally it is impossible to successfully refine the spirit pill. Ye Mo seemed to be a little curious as to why the old man would ask this question that all spirit refiners should know the answer to.

"That's right, the form of the fire attribute fairy is strange, in addition to the flame through the transformation of the fire fairy, there is also a kind of fairy like you that is itself a flame shape, a long time ago, some spirit refiners had questions, why can't this kind of flame be directly refined spirit pill?" Mu Lao nodded first, and then asked another question.

Ye Mo had never thought of directly using the Flame Immortal Spirit to refine the elixir, so he didn't know why this kind of immortal spirit couldn't directly refine the elixir, so he shook his head to show that he didn't know.

"The flame of the flame fairy itself is just a fairy, but the flame-shaped fairy is not equal to the flame, when the flame fairy is used to extract the spirit material, this kind of fairy will burn the impurities and essence of the spirit material together, and the essence can never be extracted, no one knows why this is the case, after all, the fairy spirit is too mysterious, so it can be used as a means of attack, but it cannot be used to refine the spirit pill. A hint of doubt also flashed in Mu Lao's eyes.

After a moment's pause, Mu Lao continued: "But as you said, there are exceptions to everything, there are many special flames on this plane, or in the depths of the volcano, there are lava spiritual fires that have been calcined for thousands of years, or lightning spiritual fires that have been tempered by thunder for thousands of years in the strange land of thunder, or in the body of powerful spirit beasts, there are spirit beast flames that have been nurtured for many years with spiritual energy, and even in this vast plane, there are some spiritual fires of heaven and earth that are born with heaven and earth......"

"This special flame is fused and devoured by the flame fairy, and after cultivation, it can be used to refine the elixir, and the flame fairy at this time is much stronger than the flame triggered by the aura. ”

"Many spirit refiners have been looking for all kinds of spiritual fires all their lives, but they have never been able to get what they want, after all, there are too few such strange spiritual fires, even if you are lucky enough to encounter this kind of spiritual fire, but if you want to control this spiritual fire, you must use your own flame fairy spirit to devour these spiritual fires, and the spiritual fire is all violent destruction, and the flame fairy is really fragile compared to the spiritual fire... Such an act is tantamount to setting fire to self-immolation, so only a very small number of lucky people, by such a coincidence, can refine such a small cluster of weak spiritual fires, devour and fuse them into their own flame immortals, and cultivate them into flames that can refine spirit pills, and these people, without exception, are all leaders among spirit refiners..."

Ye Mo was also a little dizzy when he heard it, and after half a sound, he suddenly thought that his flame fairy spirit had devoured the fire energy in the flint, so did it mean that he could also devour the spirit fire? Licking his lips, his eyes were firmly fixed on the purple flame in Mu Lao's hand, and when he felt it carefully, there was an illusion of burning his soul.

"Teacher's flame is also a kind of spiritual fire, right?" Ye Mo asked tentatively.

"Huh. At the mention of his own flame, Mu Laolao's face also lit up a little, and his eyes were blazing and said: "The spirit refiner of the fairy spirit plane has compiled the well-known spiritual fire into a "spiritual fire list", on which there are nine kinds of heaven and earth spiritual fire, ninety-nine kinds of special spiritual fire, and nine hundred and ninety-nine kinds of beast spirit open fire, and my fire is the "Purple Flame Soul Fire" of the seventeenth ranking of special spiritual fire , This kind of soul fire, the damage to people's souls is extremely high, only after the death of emperor-level figures, the soul is annihilated, thousands of years later, all kinds of coincidences can appear..."

"Purple Flame Soul Fire?"

Looking at the churning dark purple flame without blinking, Ye Mo muttered softly.

"In order to successfully obtain this "Purple Flame Soul Fire", I stayed in the ghost place full of dead souls for more than eighty years, and at the last moment of devouring, Rao was well prepared, and I was almost burned to ashes by the ghosts..."Mu Lao shook his head with a sigh, and on his calm old face, there was a rare hint of fear, it seems that that the encounter really made him remember it very deeply.

"Hehe, although the danger is extremely high, as long as you can get this "Purple Flame Soul Fire", everything is worth it, the flame that can scorch the soul, tsk..." Mu Lao proudly raised the dark purple flame in his palm, and said with a smile: "As long as there is a spiritual fire, in addition to the success rate of refining medicine and the increase in medicinal power, moreover, a strong person of the same level does not dare to touch this flame at all, otherwise the soul will be seriously injured, which is not so simple." ”
