The moment the ancient golden sword phantom appeared behind Su Chen, the world itself trembled.
Not from spiritual pressure.
Not from fear.
Recognition.
The heavens recognized it.
The earth recognized it.
Even the Fallen Sovereign froze completely beneath the descending sky-sized hand.
Its massive crimson eye widened violently while black demonic energy exploded around its enormous body uncontrollably.
"…Impossible…"
Its ancient voice shook slightly for the first time.
The gigantic hand crushing toward the city suddenly stopped midair.
Not because Su Chen blocked it.
Because the Fallen Sovereign instinctively hesitated.
Fear had awakened inside it.
Below the heavens, golden light continued erupting endlessly around Su Chen while the sword phantom behind him grew clearer and clearer.
Ancient runes covered the blade.
Countless names were engraved along its surface.
And every single name belonged to dead Sovereigns.
The synchronization voice echoed violently inside Su Chen's mind.
Imperial Seal Two unlocked.
Sovereign Execution Authority released.
Primordial synchronization: 100%
Then suddenly—
Everything became silent.
Su Chen's golden eyes changed completely.
They no longer resembled human eyes.
They resembled ancient stars burning through eternity itself.
Xu Mingshan's face turned pale instantly after seeing him.
"…He synchronized fully."
Yan Ruoxue slowly stood up despite the blood at the corner of her lips.
For the first time since meeting Su Chen—
Even she felt danger from him.
Not the danger of cultivation.
The danger of existence itself.
Yue Qingzhi remained silent while staring at the sword phantom behind Su Chen.
But her silver fingers tightened unconsciously around the shattered remains of her sword.
Because she recognized that weapon.
Every ancient organization recognized it.
The Heaven Slaughter Sword.
The execution blade personally wielded by the Primordial Emperor during the ancient war against the upper realms.
A weapon said to have butchered Sovereigns like livestock.
And now—
Its phantom had appeared behind Su Chen.
High above the skyline, the Fallen Sovereign suddenly roared furiously.
Black demonic energy erupted around its gigantic body like endless storms while shattered chains scattered across the heavens.
"…You should have died with the Ancient Court!"
BOOM.
The creature attacked again.
This time—
With killing intent powerful enough to destroy continents.
Its enormous fist descended toward Su Chen like a falling world while black lightning tore through the atmosphere endlessly.
The city below collapsed further beneath the pressure.
Millions screamed.
Yet Su Chen remained motionless.
Then—
He slowly raised one finger.
The golden sword phantom behind him moved simultaneously.
And slashed downward.
No dramatic movement.
No explosive technique.
Just one simple slash.
But the moment it descended—
The sky split open.
BOOM.
A golden line appeared across the heavens themselves.
Then—
The Fallen Sovereign's gigantic arm froze completely.
Silence spread through the world.
The creature slowly looked toward its own arm.
Confusion appeared within its crimson eye.
Then—
CRACK.
The entire arm separated cleanly from its shoulder.
Black blood exploded across the sky like oceans falling from heaven.
The severed arm crashed into distant mountain ranges, instantly destroying them completely upon impact.
The world froze.
Humanity stared upward in stunned silence.
A Sovereign-class monster…
Had lost its arm in one strike.
The Fallen Sovereign roared in pain and fury while staggering backward violently.
Its demonic energy became unstable.
Impossible.
That should have been impossible.
Even Yue Qingzhi's silver eyes widened slightly.
Because that attack didn't merely cut flesh.
It erased laws.
The wound on the Sovereign's shoulder refused to heal despite its terrifying regeneration abilities.
Golden energy burned continuously inside the injury like divine punishment.
Meanwhile, Su Chen slowly lifted his head.
And finally—
He spoke.
But the voice that came out no longer sounded entirely like his own.
Ancient.
Cold.
Dominating.
"You kneel before execution."
BOOM.
The atmosphere detonated.
The Heaven Slaughter Sword phantom behind him suddenly solidified further.
A terrifying sword aura spread across the world instantly.
Far away hidden sects exploded apart from the pressure alone.
Ancient weapons buried underground began trembling violently.
Even the heavens themselves dimmed slightly.
Because the sword aura carried one terrifying concept.
Death to Sovereigns.
The Fallen Sovereign instinctively stepped backward again.
Fear now filled its massive crimson eye completely.
"…No…"
Black demonic energy erupted wildly around its body while countless black seals appeared across its flesh.
The upper realms had placed restrictions on it.
Restrictions preventing retreat.
Preventing fear.
Preventing betrayal.
But now—
Those seals were breaking under pure terror.
The creature suddenly turned toward the heavens and roared furiously.
"WHY WOULD YOU WAKE HIM?!"
Its voice shook the planet.
"He's already synchronizing with the throne!"
High above the world, the clouds twisted violently.
The Observer's giant silver eye appeared again instantly.
This time—
Its cracked surface looked unstable.
Because even heaven hadn't expected the second imperial seal to awaken this early.
The Observer stared directly at Su Chen.
And for the first time—
Its emotionless gaze carried unease.
"The synchronization must not complete."
Silver lightning erupted across the heavens endlessly.
Then suddenly—
The heavenly gates began opening again.
But this time—
Not one gate.
Thousands.
Massive silver cracks spread throughout the sky across the entire planet while heavenly pressure descended endlessly.
Xu Mingshan's face completely changed.
"They're invading early…"
Yan Ruoxue cursed softly.
"The upper realms are panicking."
And they truly were.
Because the moment Su Chen awakened the Heaven Slaughter Sword—
Everything changed.
Before, he was merely the successor of the Ancient Court.
Dangerous.
Potentially catastrophic.
But still incomplete.
Now—
He had become a genuine threat to heaven itself.
The Observer's cold voice echoed globally.
"All heavenly factions…"
The silver gates widened further.
"…commence full descent."
BOOM.
The sky shattered.
Countless figures slowly appeared behind the heavenly gates.
Armored heavenly soldiers.
Saint-level war beasts.
Ancient executioners wrapped in silver chains.
Millions.
An army descending from the upper realms.
Humanity collapsed into despair instantly.
No mortal force could survive that.
The hidden cultivation world became silent with horror.
Because this was no longer a conflict between sects.
This was war between worlds.
Meanwhile, the Fallen Sovereign suddenly laughed again after seeing the heavenly armies descending.
Madness returned to its crimson eye.
"Yes…"
Black demonic energy exploded from its body again.
"YES!"
Its severed arm began regenerating forcefully despite the golden energy destroying it continuously.
The creature looked toward Su Chen with endless hatred.
"Even if I die…"
Its voice thundered across the world.
"…heaven will bury you with me!"
BOOM.
The Sovereign burned its own life force instantly.
Its aura exploded upward crazily.
Stronger.
Faster.
More violent.
The surrounding space began collapsing around its gigantic body while crimson cracks spread across the atmosphere endlessly.
Xu Mingshan's expression turned pale.
"It's sacrificing everything…"
Yue Qingzhi's silver eyes sharpened instantly.
"It wants to self-detonate."
Silence crashed across the rooftop.
A Sovereign self-destruction.
If that explosion happened—
Half the planet would disappear.
The Fallen Sovereign raised both enormous hands toward Su Chen while black demonic flames consumed its body completely.
Its laughter became hysterical.
"DIE WITH ME—"
Then suddenly—
Su Chen vanished.
The world blurred.
Before anyone could react—
He appeared directly before the Fallen Sovereign's face.
Tiny compared to the monstrous giant.
Yet infinitely more terrifying.
The Heaven Slaughter Sword phantom appeared within his hand partially now.
Not fully formed.
But enough.
Then Su Chen calmly swung downward.
One strike.
Toward the monster's neck.
