Rumble!
The earth trembled as magma erupted.
The mountain range over ten thousand zhang away seemed on the verge of splitting apart.
Suddenly, another vast wave of crimson magma swept over.
A bird flapped its wings and flew through the magma filling the sky.
The instant the bird passed through the magma, every flame within it was devoured.
Deprived of its flames, ash scattered in all directions.
Having devoured a great amount of fire, the bird steadied itself.
It resembled a Dan Crane, but it had a human face, only one leg, a blue body covered in red spots, and a white beak.
Bi Fang had barely reached the True Immortal realm and was merely an insignificant figure within the Phoenix Clan.
Still, Bi Fang possessed rather good innate foundations.
He did not eat grain, instead feeding on flames.
Throughout most of Immortal Volcano, Bi Fang was like a fish in water, able to devour vast quantities of fire every day.
After Lu Ya came to Immortal Volcano, he had Bi Fang serve as his attendant.
This alone showed that he thought highly of Bi Fang.
Given Yuan Feng's current regard for Lu Ya, even if Lu Ya wanted an Azure Luan with Golden Immortal level cultivation as an attendant, he could have one.
Thus, after becoming Lu Ya's attendant, Bi Fang not only felt no humiliation, but was instead flattered beyond measure.
A stream of divine sense emerged from Bi Fang's brow and spread across ten million li.
Sensing the changes in the earth veins throughout the region, Bi Fang was secretly astonished.
Lu Ya's Great Divine Ability and immense magical power, used to clear the earth veins, filled Bi Fang with reverence.
One had to know that the earth veins of Immortal Volcano were no trivial matter.
Even a minor earth vein of Immortal Volcano was not easy to clear; at the very least, Bi Fang found it difficult.
As for clearing a major earth vein, even the powerful figures of the clan would have to exert tremendous effort.
Yet now, Lu Ya was clearing a primary earth vein.
As far as Bi Fang knew, the minor earth veins of Immortal Volcano were as numerous as the stars in the sky, while the major earth veins numbered in the hundreds of millions.
There were only several dozen primary earth veins.
The power contained within any one of them could only be described as terrifying.
Within the clan, aside from Yuan Feng, only a handful could clear a primary earth vein.
Deep underground, several billion zhang below.
Cloudy "waves" occasionally appeared within the blazing white sea of fire.
This sea of fire was one of Immortal Volcano's primary earth veins.
Massive amounts of Innate Li Fire surged through it, along with even greater quantities of Postnatal Li Fire.
Spiritual qi, turbid qi, and other energies were mixed within as well.
Lu Ya's figure appeared within the sea of fire.
Clearing the earth veins was real enough, but Lu Ya was not doing it for a little Merit, nor was he contributing to the Phoenix Clan. He was searching for the origin of Immortal Volcano.
Yuan Feng certainly knew where Immortal Volcano's origin lay, and some of the Phoenix Clan's upper echelons surely knew as well.
But none of them would readily tell Lu Ya.
Even though he could resonate with Immortal Volcano, finding its origin was no easy task.
Still, by clearing the earth veins, Lu Ya had already found some clues.
With Lu Ya's own magical power, clearing minor earth veins was easy enough, but clearing major earth veins was rather difficult.
His ability to clear a primary earth vein came only from "summoning" part of his true body's power to bolster himself.
Feeling himself draw ever closer to Immortal Volcano's origin, Lu Ya secretly rejoiced.
It seemed he would soon find where Immortal Volcano's origin was located.
He hoped his guess was correct.
If the origin of Immortal Volcano truly came from the same source as the Sun Star, the benefits to him would be immense.
Suddenly, Lu Ya's mind and spirit stirred. A leaf he carried on his person began to glow faintly.
The leaf was small and exquisite, delicate and translucent, with a pale jade-green hue.
A faint innate radiance flowed across its surface.
It had been refined from a leaf of the Innate Wutong Tree and was also the emblem of the Phoenix Clan.
Upon closer inspection, Phoenix Script flowed across the emblem, appearing and vanishing intermittently. It carried an air of mystery, as though it were older than ancient times.
Phoenix Script was the writing invented by the Phoenix Clan.
The Dragon Clan, for example, used Dragon Script.
There were also Golden Seal Script, Jade Scroll Script, and others.
Yet only a small number of people had mastered Phoenix Script.
Even within the Phoenix Clan, few below the Grand Unity level had mastered it.
This showed just how difficult Phoenix Script was to learn.
Turning Phoenix Script into the Primordial World's common script would be a long and arduous task.
It was worth mentioning that Phoenix Clan emblems were divided into ranks as well: three innate grades and three postnatal grades.
The one Lu Ya wore was innate upper-grade, the highest rank of Phoenix Clan emblem.
Sending a thread of divine sense into the Phoenix Script emblem, he heard Yuan Feng's message.
"She wants me to go to Phoenix Cave?" Lu Ya was startled.
Phoenix Cave was located atop Immortal Volcano's main peak and was also Yuan Feng's cultivation ground.
Even within the Phoenix Clan, few were qualified to enter Phoenix Cave.
Most of the Phoenix Clan's core secrets were also kept within Phoenix Cave.
Lu Ya stepped into Phoenix Cave, while Bi Fang could only stand guard outside.
Bi Fang was not qualified to enter Phoenix Cave yet.
The moment he entered Phoenix Cave, he saw dense Innate Spiritual Qi forming into mist.
If Lu Ya used the Sun God Eye, he would be able to see an enormous tree towering in the distance: the Innate Wutong Tree.
Many nests had been built upon the Innate Wutong Tree, some five-colored, some seven-colored, and some nine-colored.
Yuan Feng's nest stood at the very top of the Innate Wutong Tree. It was also magnificent and dazzling, adorned with numerous Heavenly Materials and Earthly Treasures.
Counting them, there were thirty-seven nests on the Innate Wutong Tree in total.
The lower the nest, the smaller it was, yet even the lowest nest was a High-grade Postnatal Spiritual Treasure, with a Great Thousand World formed within it.
Yuan Feng's nest was an Innate Spiritual Treasure. Its internal space was equivalent to at least hundreds or thousands of Great Thousand Worlds.
Lu Ya was also qualified to build a nest on the Innate Wutong Tree, but his ambitions did not lie there.
The instant Lu Ya entered Phoenix Cave, Yuan Feng teleported him over.
Feeling space twist around him, Lu Ya did not resist.
After a burst of dizzying disorientation, Lu Ya was instantly teleported onto the Innate Wutong Tree, where Yuan Feng stood before him.
"Why did you summon me here, Fellow Daoist?" Lu Ya asked with a smile.
Yuan Feng did not beat around the bush and directly said that she wished to teach Lu Ya the Nirvana Method.
"The Nirvana Method?" Lu Ya was also stunned.
As far as he knew, the Nirvana Method was one of the Phoenix Clan's great divine abilities.
Yuan Feng had her own considerations.
A Grand Unity level powerhouse had joined the Phoenix Clan. No amount of importance placed on him would be excessive.
Furthermore, Lu Ya had been at Immortal Volcano for several decades.
Besides, Lu Ya had cleared quite a few earth veins, which counted as making some contributions to the Phoenix Clan.
Moreover, learning the Nirvana Method would deepen his connection with the Phoenix Clan.
This was also a bond.
After considering all these factors, Yuan Feng made this decision.
Since Yuan Feng was willing to teach him the Nirvana Method, Lu Ya naturally wished to learn it.
Six Ears was not here, but Yuan Feng still cast a spell to block the surroundings and prevent anyone from eavesdropping.
As Yuan Feng explained the Nirvana Method, Lu Ya focused wholeheartedly on comprehending it.
Nirvana rebirth was a form of Immortal Body.
Immortal Bodies were not uncommon in the Primordial World.
But Immortal Bodies existed on different levels.
Being unable to be killed by mortal weapons was an Immortal Body. Being unable to be destroyed by Postnatal Spiritual Treasures was also an Immortal Body. Being impossible to kill even with Innate Spiritual Treasures was even more so an Immortal Body.
Some beings with excellent innate foundations possessed Immortal Bodies from birth.
Take Lu Ya now, for instance. He could be reborn from a drop of blood on the Sun Star.
The Phoenix Clan's Nirvana Method, however, was different. Once cultivated, it allowed one to be reborn through fire, and each rebirth would make one far stronger.
According to Yuan Feng, if one cultivated the Nirvana Method to great completion, a True Immortal could rise to the Mystic Immortal level after one nirvana, while a Mystic Immortal could reach the Golden Immortal level after several nirvanas.
If a Grand Unity Golden Immortal underwent nirvana once, their cultivation would also improve considerably.
However, cultivating the Nirvana Method was not easy. One first had to comprehend the Law of Fire.
Anyone capable of comprehending the Law of Fire would at least be at the Golden Immortal level, right? This requirement was certainly not low.
Once the Nirvana Method was mastered, one's descendants would directly possess this divine ability through bloodline inheritance.
Under Yuan Feng's explanation, Lu Ya easily comprehended the Nirvana Method.
Lu Yang had comprehended the Law of Fire, though the Power of Law was still weak.
Therefore, his avatar could cultivate the Nirvana Method as well.
As Lu Ya cultivated the Nirvana Method, a blurred phantom appeared behind him.
