Cultivation of immortality begins with an eighty-year-old eunuch.

"Although that old dog was cunning, at the last moment of his life, he threw out the 'secret of the immortals' to tempt those four half-step Void Refinement cultivators, which was most likely true. Because only by throwing out a truly earth-shattering opportunity could he possibly make those four old monsters stop."

Chen Fan analyzed, "Moreover, this underground space is completely sealed off by the spatial turbulence barrier. If there really is an exit, apart from this altar core that is under heavy suppression, we can't think of any other place."

"We must go. Even if it's a mountain of knives and a sea of ​​fire, we have to go."

Chen Fan gripped the eleven-piece talisman tightly with his left hand and flicked his right finger, sending a gleaming golden protective talisman affixed to his chest. Then, with a thought, the three realms of his spiritual power transformed into a gray-white shield around him, protecting him completely.

"Go back and stay there!"

Chen Fan gave Wei Gonggong an instruction, then took a deep breath and leaped into the air.

"Whoosh!"

The cyan figure, like a bird in flight, leaped directly into the pitch-black abyss.

The sound of whistling wind reached my ears.

Falling.

It kept falling.

The abyss was vast, filled with an ancient and chaotic aura. This aura made Chen Fan feel inexplicably oppressed, as if a pair of indescribable eyes were coldly watching him from the darkness.

It took about half an incense stick's time to fall.

"Bang!"

Chen Fan landed steadily on the solid ground.

Beneath their feet were no longer black stone slabs, but strange crystals that emitted a faint fluorescent glow.

He looked up and glanced around.

With just one glance, Chen Fan's pupils contracted to their maximum size!

Beneath this altar lay a vast and boundless underground palace!

The dome of the underground palace was inlaid with countless fist-sized luminous pearls, illuminating the entire space as if it were daytime. And at the very center of the underground palace stood nine colossal bronze pillars, each a hundred feet tall!

Each bronze pillar is engraved with dense, intricate ancient runes so complex that a single glance would make one dizzy. These runes have an eerie dark red color, as if they were cast from the blood of countless people.

In the center of the nine bronze pillars, nine black chains, as thick as water tanks, extend from the top of the pillars, converge in mid-air, and tightly bind a humanoid creature!

"That is..."

Chen Fan suppressed the shock in his heart and carefully took a few steps forward.

"Tick-tock...tick-tock..."

In the vast, desolate depths of the underground palace, the sound of dripping water, seemingly from nowhere, echoed softly in this space that appeared to have been forgotten by time, each drop striking Chen Fan's heart.

He held his breath and activated the Fixed Word Technique to its fullest extent, transforming the three realms of intent into a thin yet incredibly resilient gray-white shield around his body.

He stood on strange crystals that emitted a faint glow, his gaze fixed on the nine bronze pillars that pierced the dome in the very center of the underground palace.

They crisscrossed in mid-air, like a net hanging in the sky, suspending the humanoid creature tightly in the very center of the underground palace.

"This is the ancient immortal that Fire Source Old Dog desperately wanted to uncover?"

Chen Fan swallowed hard, his heart pounding faster than usual.

"Tap...tap..."

Chen Fan slowed his pace, gripping the hilt of Eleven's sword tightly with his left hand, his palm sweating profusely. He approached the nine bronze pillars little by little, and with each step, he could feel the chaotic spiritual energy permeating the surrounding air becoming thicker, so thick that it gave him the illusion of sinking into a quagmire.

Fifty zhang... thirty zhang... ten zhang...

As the distance closed, Chen Fan finally managed to make out the true appearance of the humanoid creature bound by nine chains.

Just one glance!

Chen Fan's pupils suddenly contracted to the size of pinpoints. He was struck as if by lightning, gasped for breath, and the color drained from his face instantly!

Shocked!

"This...this is an immortal?!"

Chen Fan let out an incredulous exclamation in his heart.

In his past understanding, and even in the ancient records of the entire Tiannan Star cultivation world, the so-called "immortals" were all supreme beings with an immortal demeanor, surrounded by thousands of auspicious rays, and exuding an ethereal and sacred aura.

That is the ultimate goal pursued by countless cultivators throughout their lives, the supreme being who has transcended the mundane body and impure bones.

But this creature suspended by chains in front of us doesn't look like a "celestial being" at all.

The humanoid creature was less than seven feet tall, and its entire body was covered with strange keratinous layers that resembled black dragon scales. It lowered its head, and its long, jet-black hair cascaded down like a waterfall, obscuring its face.

What chilled Chen Fan to the bone was the aura emanating from this creature!

Demonic energy!

A monstrous demonic aura, pure to the extreme and so dense it was impossible to dissolve!

The black demonic energy surged and boiled around him as if it were a tangible substance, transforming into ferocious black dragon phantoms that tore and roared wildly between the nine chains.

Each surge of demonic energy caused the thick, water-jar-like black chains to erupt with a blinding flash of blood-red light, accompanied by a violent "clattering" sound.

Chen Fan had met the demonic cultivator.

In the Boundless Sea, the gathering place of all the demonic cultivators on Tiannan Star, he had slain countless ruthless demonic giants. He himself had even cultivated pure demonic energy within his body, following the path of cultivating both immortality and demonic power.

However, he dared to swear to the heavens that in his entire life, including in the memories of those Nascent Soul stage monsters he had searched, he had never seen such terrifying and pure demonic energy!

If the demonic energy emanating from those Nascent Soul cultivators in the Boundless Sea is a murky drop of water, then the demonic energy emanating from this being is a vast, boundless black ocean capable of swallowing all the heavens and myriad worlds!

This is not an immortal at all; this is an absolute and unparalleled ancient demon!

"A scam... Old Dog Huoyuan has been fooled! What's being suppressed beneath this altar isn't some ancient immortal at all, but a demon countless times more terrifying than any immortal!"

Chen Fan felt a chill run from his tailbone straight to the top of his head, and his scalp tingled.

Reason was frantically warning him: Retreat! Retreat immediately! Escape as far as possible!

Even a mere wisp of aura emanating from such a being would be enough to crush him, a cultivator in the late stage of the Nascent Soul realm, into dust.

Just as Chen Fan was about to make a hasty retreat!

A sudden change has occurred!

"Buzz!"

The golden bowl that had been resting quietly against his chest suddenly began to shake violently without warning!

The vibrations were extremely high, as if a primordial beast about to hatch was sealed inside.

At the same time, the surface of the golden bowl became extremely hot. That terrifying temperature ignored Chen Fan's late-stage Nascent Soul physical defenses and directly burned the skin and flesh on his chest, making a "sizzling" sound and sending a piercing pain through him!

"What happened?"

Chen Fan's expression changed drastically. He tried to communicate with the golden bowl using his divine sense, and even mobilized the power of the fusion of immortals and demons within his body to suppress the golden bowl's abnormal movements, but all of this was in vain!
