In an instant, Nie Kong’s figure vanished completely, and the multicolored vortex immediately resumed its spin.

Gu Quan retracted his gaze and couldn't help but ask, "Master, isn't it too rushed to let Junior Brother Nie Kong enter the 'Seven-Colored Immortal Domain' right now? The 'Primordial Heaven Cavern' opens once every ten years. Even if he misses this opening, he'll surely make it for the next one."

"It cannot wait!"

The Seven-Colored Grand Sovereign sighed heavily, a shade of worry clouding his brow. "For years now, I’ve had a nagging premonition that the Tianling Continent is on the verge of a massive upheaval."

"Ah?"

Gu Quan was startled, then seemed to recall something. "Master, is this upheaval related to the Grand Sovereign Spirit Realm?"

The Seven-Colored Grand Sovereign nodded slightly. "Since achieving the Grand Sovereign level, I have been investigating the truth behind the Spirit God War from ten thousand years ago. While I still cannot confirm it, I have made vague discoveries. If my guess is correct, the root of that divine battle must lie within the Tianling Continent."

"What?"

Gu Quan was greatly shocked. He had cultivated in the 'Seven-Colored Divine Realm' for several millennia, and this was the first time he had heard the Seven-Colored Grand Sovereign reveal such a hidden secret.

However, Gu Quan harbored no doubt about the Grand Sovereign’s words.

In fact, Gu Quan himself harbored deep doubts regarding the state of the Tianling Continent; the longer he stayed in the Grand Sovereign Spirit Realm, the heavier those doubts became.

After the divine war ten millennia ago, the continent was split into three parts, with the Tianling Continent being the most peculiar.

Across the entire continent, apart from a small number of Illusory Realms and Talisman Artifacts left over from the ancient war, there was nothing else available for cultivation. It was as if all written records had been destroyed, and the memories remaining in human minds had been thoroughly wiped clean.

Furthermore, not a single "Spirit Soul Phantom Crystal," which was necessary for Illusionary Spirit Masters to cultivate, could be found anywhere on the continent. Yet, ten thousand years ago, although the spiritual energy elements were sparse in the western region of the Illusionary Spirit Continent, "Spirit Soul Phantom Crystals" were not uncommon; tales even spoke of numerous naturally formed, top-grade phantom crystals.

Destroyed texts, erased memories, vanished crystals…

The Tianling Continent at that time was akin to a blank slate, and the current system of Spirit Master cultivation on the Tianling Continent arose from that very blankness.

But who first established this system?

Not only did Gu Quan not know, but even the Seven-Colored Grand Sovereign was ignorant of the origin.

"I originated from the Tianling Continent. Though I have attained Grand Sovereign status, I remain somewhat estranged from this Grand Sovereign Spirit Realm, and my acquaintance with Grand Sovereigns Chongxu, Lei Long, Pangu, and Pan Ling is superficial, making it difficult to uncover the deepest secrets," the Seven-Colored Grand Sovereign lamented softly. "Now, perhaps only Chongxu, Pangu, and Grand Sovereign Zhuyin of the Star-Fairy Clan—who vanished ten thousand years ago—truly know the truth of that divine war. If my suspicions are correct, Chongxu and Pangu may have already been enacting some kind of strategic plan on the Tianling Continent ten millennia ago. Once they move, those of us here, and indeed the entire Tianling Continent, face utter annihilation. Therefore, Nie Kong’s potential is astonishing; he must achieve Grand Sovereign status as quickly as possible so we can amass more strength to face the coming great change."

Gu Quan forcefully suppressed the shock surging in his chest. "Master, if that is the case, will they agree to let Junior Brother Nie Kong enter the 'Primordial Heaven Cavern'?"

"Their scheme has not yet been fully revealed. As long as Nie Kong can reach the Ninth Grade Spirit God realm, even if they wish to interfere, they won't overstep too much. After all, the hope of finding the 'Primordial Divine Crystal' within the cavern is incredibly slim; over ten millennia, only Pan Ling and Lei Long have succeeded." The Seven-Colored Grand Sovereign let out a cold sneer. "Besides, whether the 'Primordial Divine Crystal' truly exists is still highly debatable; it might just be a deception."

Gu Quan was taken aback. "Then why did you still send Junior Brother Nie Kong in, Master?"

"It contains a vast amount of 'Chaos Immortal Qi,' a detail that Chongxu and Pangu likely do not know."

"I understand now…"

"..."

...

"Whoosh!"

A faint, whistling sound flashed past, and Nie Kong instantly traversed the vortex, entering a strange space.

This space was not large, barely a few hundred meters in circumference.

The elliptical side walls of the space shimmered with brilliant, multicolored luminescence, while the interior was a sea of clouds, thick, white mist churning violently like ocean waves.

"'Chaos Immortal Qi,' where are you located?" Nie Kong’s mind stirred, and his spiritual sense immediately swept across the entire area.

However, the spiritual sense proved useless, seemingly suppressed by the power of the space itself. Nie Kong was forced to concentrate his Chaos Divine Power into his eyes, observing closely. After a dozen seconds, Nie Kong finally spotted thin, white wisps of energy darting ceaselessly amidst the rolling clouds, moving faster than lightning.

They varied in thickness, some as stout as a little finger, others as fine as threads, ranging in length from several dozen zhang down to mere meters.

In total, there were thirty-three distinct strands.

"This is the 'Chaos Immortal Qi'!" Nie Kong immediately judged.

Upon entering this space, the Chaos Divine Power within Nie Kong's body began to vibrate faintly. It felt familiar, yet unyielding, much like the lower volume of the 'Chaos Jade Scroll' he first encountered in the Pill Immortal Sect's Heavenly Fire.

"Master was not wrong; if I can fully refine all this 'Chaos Immortal Qi,' becoming a Ninth Grade Spirit God will certainly not be difficult." Joy flickered in Nie Kong's eyes.

"Swish!"

Just then, a strand of 'Chaos Immortal Qi,' as thick as a chopstick, approached him.

Nie Kong reacted with incredible swiftness. His right hand, charged to the brim with Chaos Divine Power, shot out like lightning, seizing the middle of the strand of energy.

"Whoosh!"

The strand of 'Chaos Immortal Qi' recoiled as if its tail had been stepped on, suddenly launching upward.

A surge of immense force erupted, causing Nie Kong’s palm to go numb; he felt a sensation of being unable to hold on, and the 'Chaos Immortal Qi' instantly slipped free.

Immediately following, there was a sharp hiss, and the strand of 'Chaos Immortal Qi' hurtled directly toward Nie Kong.

"Bang!"

Nie Kong didn't even have time to react before his chest took the blow. He felt as if he had been struck by a colossal hammer, his body thrown backward dozens of meters before smashing violently against the space’s side wall.

"Swish!"

The Chaos Immortal Qi pursued him.

Just as it neared the multicolored halo emanating from the space wall, it halted. It hovered, circling a few times, then plunged back into the churning mist, moving about leisurely and freely.

"What a beast!"

Leaning against the side wall, Nie Kong sucked in a sharp breath of cold air. That last impact had nearly made him vomit blood. Compared to this collision with the 'Chaos Immortal Qi,' the attacks he faced in the final stage of the 'Seven Realms Bridge of Spirit Leaves' were trivial; the difference in impact was astronomical.

Only now did Nie Kong truly understand why his master claimed this 'Seven-Colored Immortal Domain' was extremely perilous, potentially even life-threatening.

A single strand of 'Chaos Immortal Qi' was this formidable. If a dozen or several dozen strands charged at him simultaneously, even deploying his 'Crimson Star Combat Body,' Nie Kong suspected he would be pierced through and through. Unless he could retreat to the vicinity of the side wall in time, his life would be forfeit.

"Hoo!"

After a considerable pause, Nie Kong finally let out a long breath, rubbing his aching chest. His eyes shone with a brilliant light as he scanned back and forth among the thirty-three white strands of immortal energy. The more ferocious the 'Chaos Immortal Qi,' the greater the rewards upon its refinement, and the faster his own strength would improve.
