The establishment of the Endless Fire Domain was not achieved overnight. Xiao Yan used Pill City as his base and brought tens of thousands of miles of land in the Southern Region under his command. With the Burning Heaven Cauldron as the core, he set up the " Nine Revolutions Primordial Array ". The array patterns spread to every inch of land within the domain. The power of the Heavenly Flames transformed into an invisible barrier, which not only purified the remaining dark energy but also nourished all things, causing spiritual herbs and medicines within the Fire Domain to grow wildly, and the number of alchemists to surge.
At the heart of the domain, a palace built of purple-gold flame crystals rises from the ground, named " Burning Heaven Palace." At the top of the palace, the Burning Heaven Cauldron floats day and night, its alchemical flames swirling, becoming a symbol of the Endless Fire Domain. Xiao Yan sits in the position of palace master, flanked by Mo Chen and Lin Qingxue on his left and right— Mo Chen is already at the Initial Heavenly Sovereign, in charge of the alchemy of the Fire Domain; Lin Qingxue, based at the Hundred Herbs Hall, oversees the livelihood and medicinal supply of the Fire Domain.
On this day, during a meeting at the Burning Heaven Palace, Xiao Yan was listening to Mo Chen report on the progress of alchemist training in the Fire Domain when a report suddenly came from outside the hall, "Reporting to the Palace Master, Palace Master Lin Dong of the Martial Realm and Young Mu Chen of the Mu Domain request an audience."
A glint of amusement flashed in Xiao Yan's eyes. "Please come in quickly."
Before long, Lin Dong and Mu Chen walked into the hall side by side. Lin Dong was still wearing his green robe, and the fire sable on his shoulder yawned, his aura already at the Advanced Heavenly Sovereign; Mu Chen was dressed in a white robe as white as snow, surrounded by a faint spiritual aura, his strength was also not weak, and he stood firmly at the Intermediate Heavenly Sovereign.
" Xiao Yan, long time no see." Lin Dong laughed and sat down. "Your Endless Fire Domain is quite impressive, it has a bit more of a down-to-earth feel than my Martial Realm."
Mu Chen also smiled and said, " The Fire Domain is filled with the fragrance of pills and the spiritual energy is pure. No wonder it has become the third pole of the Great Thousand World in just a few years."
"It's merely taking advantage of the post-war recovery." Xiao Yan waved his hand and ordered tea to be served. "The two of you have come together, surely not just to reminisce?"
Lin Dong's smile faded as he took out a black jade slip, "This is a message brought back from the Outer Realm by my Martial Realm scouts. Although the Domain of Darkness has retreated, it seems that there are even stronger beings lurking outside the Great Thousand World."
The jade slip contained a blurry image—in the void Outer Realm, a dark shadow, obscuring the sky, was entwined with a dark origin more refined than that of the Darkness Heavenly Emperor, and countless stars could be faintly seen annihilating in its palm.
Xiao Yan's pupils contracted slightly. "This is... the power of a transcendent Heavenly Sovereign?"
"At least at the Quasi-Dominator Realm," Mu Chen said in a deep voice. "According to the ancient records of my Mu Domain, in ancient times, the Great Thousand World once fought a great war with the ' Outer Realm Evil Clan.' The Evil Clan Sovereign was such an existence, capable of devouring the origin of the world."
The three exchanged a glance, each seeing a hint of seriousness in the other's eyes. The Darkness Heavenly Emperor was merely an appetizer; the real threat lay beyond the Outer Realm.
"It seems the peaceful days are about to end before they even begin." A Heavenly Flames ignited at Xiao Yan's fingertip. "Although the Endless Fire Domain is newly established, it already has fifteen Heavenly Sovereign under its command. If a great war were to break out, it would be more than capable of fighting."
"Our Martial Realm can produce twenty Heavenly Sovereign," Lin Dong slammed his hand on the table. "We could suppress the Evil Clan back then, and we can do it again today."
" Mu Domain and the Luo God Clan join forces, they can also gather eighteen members," Mu Chen added.
The three had finalized their plan and decided to use the Endless Fire Domain as the center to unite all forces in the Great Thousand World and form the " Great Thousand World Guardian Alliance " to jointly deal with the Outer Realm Evil Clan.
After the meeting concluded, Lin Dong and Mu Chen departed, leaving Xiao Yan standing alone atop the Burning Heaven Palace, gazing at the surging river of pill fire within the domain, his mind filled with countless thoughts. He could sense the Heavenly Flames within his body subtly stirring, as if echoing some kind of power from the Outer Realm.
"Perhaps it's time to make a trip to the Pill Realm."
Xiao Yan summoned the Luo Shen Mirror, tearing through space and stepping into the Pill Realm. The Pill Realm, now reforged and sealed, flourished even more. Within the Primordial Hall, the Heart of the Pill Realm radiated a perfect light. Xiao Yan infused the Heart of the Outer Realm Evil Clan with information about the Heart of the Pill Realm, and suddenly the voice of the Pill God's lingering will echoed within the palace, " The Outer Realm Evil Clan... they have indeed come. Back then, I joined forces with Ancestor Luo Tianshen, Martial Ancestor, and Shepherd God to repel them and seal them away in the Outer Realm. Now that the seal is loosening, I fear their Sovereign is about to break free."
"Does Senior know its weaknesses?" Xiao Yan asked.
" The Evil Clan Sovereign fears the ' Great Thousand World Origin Fire,' a fire condensed from the beliefs of all living beings in the Great Thousand World. It cannot be refined by human power; only by gathering the four origins of ' Heavenly Flames, Thunder, Spiritual Essence, and Space' can it be activated." The voice of the Pill God's lingering spirit carried a hint of weariness. "You, Lin Dong, Mu Chen, and Luo Li each possess one of them."
Xiao Yan's heart stirred: Luo Li's spatial origin, Lin Dong's lightning origin, Mu Chen's spiritual origin, plus his own Heavenly Flame Origin... So that's how it is.
Upon leaving the Pill Realm, Xiao Yan immediately sent messages to Lin Dong, Mu Chen, and Luo Li, agreeing to meet in the Endless Fire Domain three months later to discuss activating the Great Thousand World Origin Fire.
In March, Xiao Yan was not idle. He ventured deep into the forbidden Fire Domain, " Burning Heaven Abyss," where the most concentrated Heavenly Flames were found, hiding a Heavenly Flames that had never appeared before—" Chaos Sacred Flame." After a hundred days of fierce battle with the Chaos Sacred Flame, Xiao Yan finally subdued it using the Heart of the Pill Realm and his own bloodline as a guide, bringing his total number of Heavenly Flames types to six and his strength to break through to the Advanced Heavenly Sovereign.
When the three-month period ended, Lin Dong, Mu Chen, and Luo Li arrived as scheduled. Luo Li was wearing the Luo God Clan armor, and her spatial laws were becoming more and more harmonious, indicating that she had reached the Intermediate Heavenly Sovereign. The four of them gathered at the Burning Heaven Palace and, following the guidance of the remnant will of the Pill God, each circulated their original power and headed towards the " Great Thousand World Altar " in the center of the Fire Domain.
The altar was constructed of chaotic crystal and engraved with ancient runes. The four people stood at the four corners of the altar, and the four primal forces of Heavenly Flames, thunder, spiritual energy, and space soared into the sky, intertwining into a dazzling pillar of light above the altar.
The beam of light pierced through the clouds, reaching the very origin of the Great Thousand World. In an instant, a strange tremor surged in the hearts of all living beings in the Great Thousand World, and countless tiny points of light converged from all directions, merging into the beam of light.
The points of light multiplied, eventually coalescing into a golden flame containing boundless vitality and destructive power— the Great Thousand World Origin Fire!
"It's done!" The four of them breathed a sigh of relief at the same time.
Just then, a massive rift suddenly opened in the Outer Realm void, and a dark figure descended—it was the Evil Clan Sovereign. He gazed at the golden flames on the altar, his eyes flashing with greed. "Finally... this Great Thousand World Origin is enough for me to break through to the Dominator Realm!"
With a wave of his hand, the Evil Clan Sovereign unleashed a torrent of darkness that instantly engulfed half of the Endless Fire Domain.
Xiao Yan and his companions' eyes sharpened, and they simultaneously activated the Great Thousand World Origin Fire: " Outer Realm evil spirits, get out of the Great Thousand World!"
Golden flames transformed into a pillar of fire that pierced the heavens and earth, colliding with the dark torrent. All living beings in the entire Great Thousand World could witness this earth-shattering scene, and countless cultivators spontaneously gathered their power, merging it into the pillar of fire.
The great war broke out once again. This time, it concerned the survival of the entire Great Thousand World. Xiao Yan stood on the altar, feeling the Heavenly Flames surging within his body and the faith of all living beings in the Great Thousand World, his eyes burning with an unprecedented light.
He knew that this was not only a battle to protect, but also an essential step on his path to becoming Dominator Realm.
