I have changed my destiny and become an unparalleled immortal.

His divine sense locked onto the red butterfly mark and wrote:

[Time and Space Node: September 15th, Daoyuan Year 3250, Wei Hour (1-3 PM)]

[Location: Border of the Great Jin Dynasty, Cave of Ten Thousand Bones, Reversal in Place!]

The notification flashed by briefly: "[Deduct 22 years of lifespan]".

A spatial law, a thousand times more terrifying than slaughter, suddenly enveloped Gu Yun, who was hiding at the bottom of the pit.

The space deep within the Cave of Ten Thousand Bones experienced a violent distortion.

Gu Yun's figure completely disappeared from the present world.

Daoyuan three thousand two hundred and fifty years, September 15th, no time.

The Ten Thousand Bones Cave is located at its deepest point.

"Buzz".

Accompanied by an extremely subtle fluctuation of spacetime laws, a person suddenly appeared three feet deep in the solid rock layer beneath the Ten Thousand Bones Cave.

There was no light, no air, not even a crack!

The moment Gu Yun transmigrated, he was seamlessly molded into the pristine rock and soil of twelve years ago!

The terrifying pressure of billions of tons of earth instantly squeezed into his internal organs from all directions.

If it were an ordinary Foundation Establishment cultivator, or even a typical Golden Core cultivator, who were suddenly trapped in a solid rock layer without using earth-遁术 (earth-遁术 is a type of magic that allows one to escape through the earth), they would instantly be crushed into a pile of minced meat by this terrifying compressive force.

But who is Gu Yun?

He is a pure body cultivator who has cultivated the Great Wilderness Body to the level of Copper Blood and Stone Bones!

"Click-clack..."

Gu Yun's dark bronze skin shimmered with a glassy, ​​jade-like light as he withstood the immense pressure from the ground, enough to flatten even the finest steel.

His eyes were closed, and his mouth and nose were completely sealed with mud, but he had already activated the "Turtle Breathing Technique".

My heart rate plummeted to a mere, almost imperceptible beat every half hour.

The blood was almost frozen.

Within a short span of half an incense stick's time, his body temperature dropped to the same level as the surrounding cold rocks.

At this moment, he dared not release even the slightest bit of his divine sense, completely transforming himself into a fossil buried underground for millions of years!

And just three feet above his head...

"Ahhhhh!"

A piercing scream pierced through the rock strata and reached Gu Yun's ears.

It's the Yin Sha Old Demon!

The old demon was sitting cross-legged on the white bone stone platform.

His entire body was enveloped in a thick layer of black and red demonic energy.

His face was extremely distorted, and blood was flowing from his seven orifices. He was clearly at the most critical and painful moment in his fight against the Heart-Eating Calamity!

The violent spiritual energy of the Golden Core stage raged wildly within the cave, shattering the surrounding stalactites.

The old demon's divine sense frantically swept through every corner of the cave, guarding against any possible guardians or attackers.

His turbulent divine sense swept across the white bone stone platform, across the cave ceiling, across the cave entrance...

But they didn't bother to explore the solid rock layer beneath them!

Who would bother to investigate a dead rock that hasn't moved in tens of thousands of years?

Gu Yun was like an extremely patient ancient hunter, quietly lying dormant in the soil.

One hour.

Two hours.

Four hours...

Time passed slowly, and the noise above grew louder and louder.

The roar of the Yin Sha Old Demon had become hoarse, and the surrounding demonic energy churned violently, as if it would explode out of control at any moment.

Finally, midnight arrived!

"BOOM!!"

An incomparably powerful pressure, several times stronger than before, suddenly shot up from the white bone stone platform! This pressure even penetrated the extreme yin energy of the Ten Thousand Bone Cave and soared straight into the sky.

Golden Elixir Perfection!

"Hahahaha! Hehehehe..."

The Yin Sha Old Demon's manic, weak yet wildly joyful energy reverberated throughout the cave.

"So what if the Heavenly Demon devours my heart? I've endured it! I've finally reached the Great Perfection of the Golden Core stage, and I'm only one step away from the Nascent Soul path! Hahahaha!"

As he laughed, with a "whoosh," the Yin Sha Old Demon suddenly spat out a mouthful of foul-smelling black blood.

At this moment, although he had broken through his cultivation level, his meridians were exhausted and his golden core was weak due to his forced struggle against his inner demons. He could not even exert one-tenth of his full magical power. This was the weakest half hour of his life!

The old demon wiped the black blood from the corner of his mouth, exhaled a long breath, and finally relaxed his nerves that had been tense for three months.

He sat cross-legged, preparing to close his eyes and guide the spiritual energy of heaven and earth to repair his riddled meridians.

"This Cave of Ten Thousand Bones is indeed an excellent place for secluded cultivation. As long as I quietly recuperate here for three days, after I emerge from seclusion, who in the entire Cangbei Spirit Domain can..."

The old demon Yin Sha's mutterings had not yet ended.

An unexpected change has occurred!

"You don't have three days left, you old dog."

A whisper, seemingly from the depths of hell, suddenly rang out beneath the feet of the Yin Sha Old Demon!

"What?"

The old demon Yin Sha's hair stood on end. His instincts as a Golden Core cultivator at the peak of his cultivation made his scalp tingle, and an unprecedented sense of life-or-death crisis instantly enveloped his entire body.

He instinctively wanted to take off.

But it was too late!

"boom!!!"

The white bone stone platform where the Yin Sha Old Demon sat, along with the three-foot-long solid rock layer below, instantly shattered like a volcano!

Rock fragments flew through the air, and dust swirled wildly!

A dark bronze figure, like an ancient dragon bursting from the earth, carrying terrifying physical power accumulated over five hours, shot directly into the sky from the ground!

There were no fluctuations of spiritual energy, no sword light or magic, only extreme violence that was so fast that even divine sense could not catch it!

"Pfft!"

Gu Yun's thick right hand, forged from black iron, pierced through the Yin Sha Old Demon's unsuspecting lower body with perfect precision and extreme brutality the moment the white bone stone platform shattered!

With five fingers like hooks, carrying destructive power, it struck straight at the heart of the matter, firmly grasping the old demon's dark golden core in his dantian!

"Aaaaaaaahhhhhh!!"

The Yin Sha Old Demon let out the most miserable and desperate scream of his life!

The excruciating pain of his lower body being pierced through, along with the terror of his golden core being held tightly by an outsider, instantly twisted his withered face into that of a demon.

"Who...who are you?!"

The Yin Sha Old Demon spat out blood, his eyes almost bulging out of their sockets, staring intently at Gu Yun, who was standing right in front of him.

He couldn't understand in his wildest dreams why there was a living person buried beneath the stone platform where he had been in seclusion!

"I'm here to kill you!"

Gu Yun's eyes turned bloodshot, and the devouring power of the Thirteen Pearls of the Purple Mansion erupted exponentially at this moment!

"Suck it, you bastard!!"

"boom!"

Yin Sha Old Demon felt as if his soul, blood, and the newly broken Golden Core essence had encountered a black hole in the starry sky, and were frantically flowing out through Gu Yun's arm!

"No! I've only just reached the Great Perfection stage! I'm not satisfied!!"

The Yin Sha Old Demon struggled desperately, trying to destroy his golden core and perish together with others.

But he was too weak at the moment. Gu Yun locked his energy, preventing him from detonating even a trace of magic power!

Just ten breaths!

"Gulp... gulp..."

The terrifying sound of swallowing echoed within the Cave of Ten Thousand Bones.

The Supreme Elder of the Hehuan Sect, renowned throughout Cangbei.

The newly ascended demon king, who had just reached the Great Perfection of the Golden Core stage, hadn't even figured out Gu Yun's identity when he was sucked dry and turned into a withered skeleton in his secluded cultivation room!

"Bang!"

Gu Yun casually pulled out his right arm, threw the Yin Sha Old Demon's dried corpse on the ground like a rag bag, and then tore off his storage ring.

An unprecedented surge of energy coursed through his body.

Although the Yin Sha Old Demon was weak, he was still a true Golden Core cultivator at the Great Perfection stage!

This immense fortune surged directly into Gu Yunkong's vast dantian, and was subsequently drawn into his purple palace.

"Buzz! Buzz!"

Within the Purple Mansion, the two illusory beads representing [Touch] and [Intent] solidified instantly under the infusion of this massive energy, transforming into two dazzling Dao Foundations that crashed down!

Thirteen foundational stages, Great Perfection!

Gu Yun felt his soul let out a joyful roar, and the power of his physical body doubled once again.

At the same time, deep within Gu Yun's sea of ​​consciousness, the Book of Destiny erupted with a dazzling dark golden divine light!

[Slayed the Golden Core Grand Perfection cultivator, the Yin Sha Old Demon.]

[Life Deprivation: Deprives the deceased of 1% of their remaining lifespan, granting them an additional three years of lifespan.]

[The subject's current total lifespan: 373 years.]

"Only three years? That makes sense. This old dog was on the verge of death when he went into seclusion to break through, so he didn't have many years left to live."

Gu Yun looked at the panel and grinned. "After deducting the costs of twenty-two years, the net loss is nineteen years of lifespan. But... nineteen years of life in exchange for Wan Yin surviving, this deal is a steal!"

Gu Yun erased the words on the red butterfly: "The 3250th year of Daoyuan, the 15th day of the 9th month, at the hour of Wei (1-3 PM)."

"Whoosh!"

Red butterflies flutter their wings!

The laws of spacetime enveloped Gu Yun once again, and his figure instantly faded away from the spot, turning into specks of red light and completely disappearing into spacetime!

...

In the present world, on the border of the Great Jin Dynasty, lies the Cave of Ten Thousand Bones.

"call!"

With a spatial distortion, Gu Yun's figure fell into the dusty cave out of thin air.

He gasped for breath and looked up to see that the stone platform he had smashed twelve years ago was still in ruins, covered with a thick layer of dust and cobwebs from the years gone by.

"I'm back..."

Gu Yun touched the red butterfly mark between his eyebrows, a wild and arrogant smile playing on his lips.
