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

"Go in!" Rosa roared.

Without hesitation, Chen Fan leaped into the stone coffin and sat down cross-legged, facing the ancient demon's true form.

"Hold fast to the altar, circulate your immortal and demonic spiritual power, and draw upon the source!"

Rosa's remnant soul instantly transformed into countless starlight, all of which poured into the array nodes surrounding the stone coffin. At this moment, the stars in the entire Starry Sky Palace spun wildly, and endless starlight cascaded onto the stone coffin like a waterfall.

Chen Fan closed his eyes tightly, pushing the immortal and demonic spiritual power within his body to its limit.

In an instant, the ancient demon's true form seemed to be drawn by something, slowly opening its empty eyes. Then, the true form transformed into countless dark golden threads of law, like countless mad snakes smelling blood, frantically burrowing into Chen Fan's body!

"what!"

Even someone as resolute as Chen Fan couldn't help but let out a mournful roar at that moment.

Pain! An excruciating pain that defies description!

Every meridian was being forcibly torn and widened; every inch of flesh was being crushed and reassembled; even the deepest marrow was being cruelly replaced by that dark golden ancient magic!

Immortal and demonic spiritual power clashed and merged with the ancient demonic essence within his body. The Crimson Emperor Burning Heaven Technique automatically activated in his sea of ​​consciousness, transforming into a sky full of crimson flames, attempting to blend these two violent forces together.

This is an extremely long and dangerous process.

Chen Fan's consciousness gradually blurred amidst the excruciating pain, and finally, he fell into an endless slumber.

The lid of the stone coffin slowly closed, completely sealing away the terrifying bloodlust and the mournful roar within.

The Starry Sky Palace fell silent once more, with only the dark golden stone coffin pulsating rhythmically under the starlight.

……

Ten years have passed in the blink of an eye.

Tiannanxing, Dayuan Kingdom.

The once prosperous and bustling Dayuan is now shrouded in a depressing gloom.

Deep within the Qingyun Sect's array core, before the massive array connecting to the underground sealed land, Emperor Jianwen stood with his hands behind his back.

Ten years had not left many marks on Emperor Jianwen's majestic face, but his tightly furrowed brows and deep weariness in his eyes revealed the immense pressure he was under.

"Buzz!"

The array's light barrier trembled violently, and a jet-black demonic aura, exuding a pungent stench of blood and decay, actually spilled out from the crack in the array, transforming into a hideous ghost face that roared toward Emperor Jianwen!

"presumptuous!"

Emperor Jianwen snorted coldly, and a powerful aura of true dragon energy erupted from his body, transforming into a golden dragon shadow that instantly pulverized the demonic energy.

"Your Majesty, please calm down!" Behind him, several high-level array masters from the Great Abyss turned pale with fright and immediately knelt down.

"Calm down?" Emperor Jianwen turned around, his gaze sweeping over the group of array masters like lightning. His voice was filled with suppressed rage. "Ten years! The demonic energy overflowing from this sealed land is becoming more and more frequent. The outer ruins of the Qingyun Sect have been completely eroded by the demonic energy. Tell me, how much longer can this array hold out?!"

The leading white-bearded elder trembled, cold sweat dripping from his forehead: "Your Majesty... The power of that being underground has recovered extremely rapidly in the last ten years. Although this ancient seal is profound, it has, after all, endured countless years, and its foundation has begun to decay. If... if there is no overwhelming force to suppress it, the seal will surely break in at most twenty years!"

"Twenty years..."

Emperor Jianwen closed his eyes and took a deep breath.

Twenty years may be a long time for ordinary people, but for cultivators, it is just a short period of seclusion.

Day after day, demonic energy, like water bursting its banks, surged forth from the old monster deep underground, eroding the spiritual veins of this land.

"Reinforce the formation." Emperor Jianwen's voice was somewhat hoarse, yet it carried an undeniable authority. "Gather all the spirit stones and formation materials from the Great Abyss. Even if it means emptying the national treasury, you must weld this seal shut for me!"

"Your humble servants obey the imperial decree!" The array masters, as if granted a pardon, scrambled to set up the array plates.

Emperor Jianwen opened his eyes again, staring at the churning black energy in the array's cracks, a complex light flashing in his eyes.

"Master..."

"More than fifty years have passed. If you don't return, this Great Abyss may truly become a living hell..."

Emperor Jianwen sighed, his golden dragon robe fluttering in the gale-force winds emanating from the array. He knew that the power of the Great Abyss alone was no match for the Soul Refining Sect Ancestor who had once made the entire cultivation world tremble.

My only hope rests on my master.

……

Deep within the boundless sea and the chaotic realm lies the Starry Sky Palace.

Another decade has passed.

Twenty years have passed since Chen Fan entered the stone coffin to receive the inheritance.

The dark golden stone coffin still lay quietly in the center of the hall. The blood aura emanating from its surface was no longer as violent and overflowing as it had been at first. Instead, it had been contained into a layer of dark red aura that seemed to have a tangible presence, expanding and contracting like breathing.

As starlight coalesced, Rosa's remnant soul reappeared beside the stone coffin.

His figure was even more ethereal than it had been twenty years ago, as if a gust of wind could blow him away. This was because he had used most of the power of this inheritance space to maintain the fusion process within the stone coffin.

Rosa's gaze pierced through the walls of the stone coffin, looking directly at Chen Fan lying inside.

Upon seeing this, even the ancient demons who had once roamed the starry sky couldn't help but gasp in shock.

"Hiss... This kid actually managed to do that!"

Inside the stone coffin.

Chen Fan's body, which originally belonged to the human race, has undergone earth-shattering changes.

His skin was no longer the fleshy color of an ordinary person, but instead possessed a translucent, dark jade-like luster. Beneath his skin, faint, dark golden ancient demonic runes flowed. His originally handsome face became even more resolute, and between his brows appeared a crimson mark like a leaping flame—the very mark of his mastery of the Crimson Emperor's Heaven-Burning Technique.

What shocked Rosa the most was the circulation of power within Chen Fan's body.

Immortal energy, demonic energy, and the violent origin of the ancient demon's body—these three forces, which should repel each other and shatter into pieces upon encountering each other, have now formed a flawless Tai Chi Yin-Yang symbol in Chen Fan's dantian and meridians!

The ancient demonic essence transformed into the most powerful physical barrier; demonic energy dominated the realm of slaughter and destruction; while that mysterious immortal energy, like a stabilizing force, neutralized and regulated all the power, ensuring its endless vitality.

"A perfect fit...no, this goes beyond a perfect fit!"

Rosa was trembling with excitement, her eyes filled with incredible fervor.

"I thought he could only fuse with 30% of my physical power at his limit, but I never expected that he would actually dismantle and shatter the laws of the Ancient Demon's True Body, completely transforming them into a part of his own power system!"

"This isn't accepting the inheritance; it's devouring it!"
