The Number One Immortal Body

The old mentor of the Chosen One was named Nine Heavens Mystic Sovereign, a top-tier powerhouse hailing from the Sacred Domain.

The Sacred Domain is the central and largest realm in the entire Cangming Realm, dwarfing the Green Wood Domain where Gu Qingfeng currently resides by tens of thousands of times. It can be considered the geographical and spiritual heart of the Cangming Realm, the true core region.

Thanks to its superior location and vast territory, even the mightiest imperial sects and immortal clans couldn’t dominate it alone. Yet, none of the major factions were willing to relinquish their claim, leading to a situation where nearly every top-tier force in the Cangming Realm maintained a foothold there. This resulted in a land of divided powers and endless emergence of formidable figures.

During the peak of the Sword Sect’s glory, they too held a place in the Sacred Domain. Unfortunately, their decline left them unable to even hold onto their base in the Green Wood Domain, let alone the Sacred Domain.

Nine Heavens Mystic Sovereign stood among the pinnacle figures of the Sacred Domain.

Yet, fate had it that he crossed paths with Gu Qingfeng, ultimately meeting a soul-shattering end.

As Gu Qingfeng sorted through the memories inherited from Nine Heavens Mystic Sovereign, countless divine techniques and cultivation insights were fully absorbed. From now on, he could boast about being a reincarnated supreme being without fear of being exposed.

Of course, his focus remained on the Immortal-Demon Body Refining Art.

True to its legacy as the inheritance of the Hundred Refinements Heavenly Emperor, the Immortal-Demon Body Refining Art was no less profound than the Sword Canon. It would take at least three days to fully comprehend.

Still, after a quick overview, Gu Qingfeng grasped its fundamental principles.

Now he understood why a technique meant to forge an immortal body bore the word "demon" in its name.

Because this art was, in essence, a demonic path—helping oneself ascend by preying on others.

The core of the technique boiled down to two words: Devour.

The Hundred Refinements Heavenly Emperor was once a mere mortal. How could a mortal body transform into an immortal one out of thin air?

What was the solution?

Take it by force.

If you didn’t have it, but others did, then you just had to steal it.

Thus, the Hundred Refinements Heavenly Emperor relied on this demonic art, step by step, consuming one person after another, refining his physique until it evolved into an immortal body.

This was why the technique was called the Immortal-Demon Body Refining Art.

The saying "One general's triumph is built upon ten thousand bones" perfectly described the Hundred Refinements Heavenly Emperor. His path to supremacy was paved with the corpses of countless prodigies.

But what could he do? Most prodigies were born with divine or sacred constitutions.

The Hundred Refinements Heavenly Emperor was a ruthless man. As a mere mortal, how else could he rise?

The favored sons of major factions were born at the summit, backed by millennia or even tens of millennia of accumulated resources.

To surpass them, one had to be more ruthless than them—more ruthless than everyone.

And once you succeeded, no one would remember your humble beginnings. They would only remember you as the Heavenly Emperor!

The Hundred Refinements Heavenly Emperor was a living example. Tens of thousands of years later, his name had become synonymous with perseverance, a model used by sects to motivate their disciples.

Whenever he was mentioned, people spoke of his relentless effort, his unyielding will—how he, a mere mortal, forged an immortal body through sheer determination and ascended to the throne of a Heavenly Emperor.

As for the countless prodigies who died by his hand? Well, no one remembered them.

At this moment, Gu Qingfeng couldn’t help but sigh at the irony of fate. To think such an evil demonic art had fallen into his hands—wasn’t this practically forcing him onto the path of a demon?

"Heaven’s gifts cannot be refused without inviting calamity."

Thus, Gu Qingfeng had no choice but to accept fate’s arrangement.

Of course, "devouring" people wasn’t meant literally. It referred to plundering their bloodlines, akin to genetics. By obtaining a trace of their bloodline essence, one could use the Immortal-Demon Body Refining Art—along with vast resources—to fully assimilate it.

This raised an issue: if you seized the entirety of someone’s bloodline, you wouldn’t need as many resources to cultivate it, though some expenditure was inevitable due to losses during extraction.

But if you only obtained a single drop of blood, nurturing it into a mature constitution would demand an astronomical amount of resources.

Thus, cultivating the Immortal-Demon Body Refining Art wasn’t just about plundering bloodlines—it also required plundering resources.

By the time the Hundred Refinements Heavenly Emperor forged his immortal body, he had devoured at least ten perfected sacred constitutions and the entire treasury of an imperial immortal sect.

This alone showed how insanely demanding the conditions for an immortal body were.

But that wasn’t all. Those ten perfected sacred constitutions couldn’t just be any random type—they had to be of the same origin.

Take, for example, the Flawless Immortal Body, one of the immortal constitutions. To forge it using the Immortal-Demon Body Refining Art, one needed to devour ten perfected-level Flawless Sacred Constitutions (an advanced version of Nangong Xue’s Flawless Divine Body) or similar types like the Jade Purity Sacred Body or Saintly Purity Body, plus an ocean of resources.

Sacred constitutions weren’t common. Just look at the Sword Sect—aside from Gu Qingfeng, only Chu Jingchen possessed one. The entire Green Wood Domain might not even have ten sacred constitutions.

And the hardest part? They had to be perfected.

After decades of relentless effort, Gu Qingfeng had only brought his three sacred constitutions to the Great Completion stage—still far from perfection.

Difficult. Forging an immortal body was insanely difficult.

Gathering the materials alone was a nightmare, but the process itself was even worse—it would inevitably provoke countless factions, possibly turning the entire world against him.

But no matter how hard it was, he had to do it. After all, this was the legendary immortal body—the passport to becoming a Heavenly Emperor!

Yet, for Gu Qingfeng, there was an even deadlier obstacle beyond the usual challenges.

His multiple constitutions. Normally, this would be a blessing, but an immortal body represented the pinnacle of purity—an ultimate, singular path.

This was why one needed ten sacred constitutions of the same origin. If they conflicted, the immortal body would fail.

Gu Qingfeng’s four sacred constitutions were all completely different.

The Primordial Divine Sacred Body embodied the Dao of Energy.

The Jade-Crushing Dragon-Elephant Body represented the Dao of Strength.

The Indestructible Sword Body was the Dao of the Sword.

The Seven-Aperture Exquisite Body was the Dao of Enlightenment.

These four were as incompatible as fire and water.

To forge an immortal body, he would have to choose one path and abandon the others, committing fully to a single Dao until he reached its zenith.

As for his earlier idea of refining all four into immortal bodies? Impossible. An immortal body was the ultimate endpoint of a Dao—it couldn’t coexist with others.

Faced with such a dilemma, Gu Qingfeng’s answer was simple:

"Children make choices. Adults take them all."

The Immortal-Demon Body Refining Art detailed methods to forge various immortal bodies, each differing based on the target constitution.

Generally, immortal bodies weren’t ranked—they simply emphasized different aspects. There were no invincible constitutions, only invincible people. Even the strongest body depended on its wielder.

Yet, even among these peerless immortal bodies, one stood above the rest as the undisputed supreme:

The Chaos Body.
