The spiritual energy was restored, and he became a mortal immortal in two days.

The old woman gritted her teeth and summoned a bronze mirror. The mirror's light surged, barely blocking most of the black needles, but more than ten of the protective spiritual lights pierced through her and pierced her shoulder and chest!

"puff!"

The old woman vomited blood and knelt on the ground, her face deathly pale.

"Elder!"

The clansmen wept bitterly and rushed forward, offering their lives to protect him.

"A bunch of ants."

The shadowy figure scoffed and was about to strike again.

At that very moment—

"call out!"

A streak of azure light pierced through the sky from the south!

Before the light even arrives, the sword intent has already descended!

The sword intent was like a frozen river that had stood for ten thousand years, like a fierce wind from the heavens, instantly sweeping across the entire Demon Suppression Cliff!

All the demonic energy vanished silently the moment the sword intent swept across, like ice and snow meeting the blazing sun!

The figure in black's expression changed drastically: "This is...!"

The cyan light landed and transformed into a figure in a cyan robe.

Chen Xuan.

The old woman struggled to lift her head, looking at the suddenly appearing figure, her voice trembling: "Your Excellency...who are you?"

Chen Xuan did not turn around, but simply said:

"A descendant of the Ying family?"

"They are from my Ying family."

The old woman, panting, said, "I am Ying Yuehua, the current patriarch of the Ying clan."

"Descendants destined by Heaven."

Chen Xuan said in a low voice, his tone carrying a hint of...complexity, "Nine thousand years have passed, and you are still guarding this place."

Ying Yuehua was taken aback: "Your Excellency... knows my ancestor?"

Chen Xuan did not answer.

He looked up at the dark figure, a hint of coldness finally appearing in his eyes:

"Tianyuan Old Demon".

"Nine thousand years ago, I sealed you in this place, thinking that you could repent."

I never expected... that you would remain so unrepentant.

The dark figure trembled violently, its crimson eyes fixed on Chen Xuan, its voice distorted:

"You... what did you say?! You were the one who bestowed this title upon me nine thousand years ago?!"

It carefully discerned Chen Xuan's aura, then suddenly screamed:

"No! This sword intent... this sword intent is..."

Its pupils constricted sharply, and its voice was filled with disbelief:

"The Mysterious Heaven Sword...you are the master of the Mysterious Heaven Sword?!"

"The Master of the Mysterious Heaven Sword?!"

Ying Yuehua trembled violently, scrambling to her knees as she stared intently at Chen Xuan, tears streaming down her face: "The legendary Xuan Tian Sword Master... nine thousand years ago, the one who used the Xuan Tian Sword to slay the Demon Emperor, suppress the Heavenly Abyss, and seal away the extraterrestrial demons... the Xuan Tian Sword Master?!"

She sobbed uncontrollably: "When my ancestor Ying Tianming was alive, he said that he was able to seal Tianyuan entirely with the help of a powerful figure who called himself the 'Master of the Mysterious Heaven Sword'."

"That powerful being's cultivation was unfathomable. After sealing the seal, he vanished without a trace and never reappeared... So... so it was you?!"

Chen Xuan did not deny it.

He simply stared at the dark figure, his voice calm:

"Tianyuan, nine thousand years ago, I considered your arduous cultivation journey and only sealed you away, not killed you. Today..."

He raised his hand, and a wisp of pure white sword light appeared at his fingertips.

"Since you are so stubborn, then... destroy you."

The dark figure roared, "Master of the Profound Heaven Sword! You sealed me nine thousand years ago, and now you want to kill me?!"

"I have been imprisoned for nine thousand years and have long since forged an immortal demonic body! You think you can kill me with this avatar whose cultivation has not yet recovered?!"

It laughed wildly, its demonic energy surging, transforming into a ten-zhang-tall demonic shadow, its claws tearing through space as it slashed down at Chen Xuan's head!

This grab contained the full power of a mid-stage Nascent Soul cultivator. Wherever the demonic energy passed, rocks shattered and vegetation withered!

Chen Xuan remained completely still.

He pointed his fingers together like a sword, and a wisp of pure white sword light slowly condensed at his fingertips.

It is neither a law nor a great principle.

It's just one move... a pure sword technique.

This is the first move of the "Mysterious Heaven Sword Technique".

Nine thousand years ago, he used this move to kill the strongest demon emperor at the time.

"Mysterious Heaven - Broken Abyss".

A light stroke with the sword's finger.

The pure white sword light transformed into a single line, like a heavenly blade cleaving down!

The instant the sword light touched the demonic shadow—

"laugh!"

That ten-foot-tall demonic figure was split in two!

The cut was as smooth as a mirror, and the demonic energy was completely purified by the pure white sword light before it could dissipate!

"ah!!!"

Tianyuan screamed in agony as half of his demonic body fell, crashing heavily in front of the Demon Suppression Tower, sending up a shower of rubble! The other half of his demonic body tried to escape, but was locked on by the sword light and unable to move!

"you......"

Fear finally crept into Tianyuan's voice, "Your sword... is stronger than it was nine thousand years ago?!"

"For nine thousand years, you have been trapped in the mountains, regressing instead of advancing."

Chen Xuan said calmly, "And I, in the mortal realm... have never ceased my cultivation."

He stepped forward and stood before the half of the demon's body that had fallen from the heavens.

"If you forge an immortal demonic body, I will use the Xuan Tian Sword... to slay you nine thousand nine hundred and ninety-nine times."

He raised his hand and made a series of sword-like gestures.

"Hiss hiss hiss hiss!"

Countless pure white sword lights fell like raindrops on banana leaves, tearing Tianyuan's demonic body into pieces, one after another, layer after layer!

Each sword strike purified a piece of the demon's body; each sword strike caused Tianyuan to let out a heart-wrenching scream!

"I...I'm not reconciled!!!"

Tianyuan's roar gradually weakened.

He tried to reconstruct his demonic body, but the Xuan Tian Sword Intent was like a malignant tumor clinging to his bones; every inch he reconstructed was destroyed!

From a ten-zhang (approximately 33 meters) demonic shadow, to five zhang (approximately 33 meters), one zhang (approximately 33 meters), three chi (approximately 1.5 meters), one chi (approximately 1.5 meters)...

In the end, only a fist-sized black ball of light remained, suspended in mid-air, trembling violently.

That was Tianyuan's last primordial demon core.

"Please...please..."

Tianyuan's voice was as weak as a mosquito's buzz, "Spare my life... I'm willing... to submit for eternity..."

Chen Xuan looked at the demonic core with a calm expression:

"Nine thousand years ago, I also gave you a chance."

He pointed with his fingers and tapped lightly.

"But you didn't cherish it."

"Pfft!"

The demon core shattered, turning into specks of black light, which were then completely purified by the pure white sword light.

The Old Demon of Tianyuan has fallen.

The wind howled on the Demon-Suppressing Cliff.

The Ying family members knelt on the ground, gazing at the figure in blue robes standing with his hands behind his back, weeping uncontrollably.

Ying Yuehua prostrated herself on the ground, her forehead striking the gravel, drawing blood.

"Ying Yuehua, the 73rd generation patriarch of the Ying clan, pays respects to the Xuan Tian Sword Master!"

"For nine thousand years, the Ying family has taken pride in protecting this seal! Today, to have the Sword Master himself present, the Ying family... can die without regret!"

Behind them, all the members of the Ying family kowtowed in unison:

"Greetings, Master of the Mysterious Heaven Sword!"

Chen Xuan turned around, looking at this group of guardians who had stood firm for generations, a hint of tenderness flashing in his eyes:

"Get up. You have guarded this place for nine thousand years. You have worked hard."

He raised his hand, and the pure white sword light disappeared into the body of the Demon Suppression Tower.

In an instant, all the runes on the tower relit, radiating golden light! The cracks on the Nine Provinces Mystic Pearl began to slowly heal!

The seal... has been re-established!

"I reinforced the seal."

Chen Xuan said, "For the next thousand years, the demonic energy of Tianyuan will no longer leak out. You... can now relieve yourselves of some burdens."

Ying Yuehua, tears streaming down her face, said, "The Sword Master's great kindness will be forever unforgettable for the Ying family!"

Chen Xuan didn't say anything more.

He looked up at the northern horizon, where a faint trace of demonic energy still lingered.
