That heavy pressure from the sky did not last long.
Kenya frowned and watched for a while, then saw the shadow in the sky quickly disperse.
"A mirage? Or some giant summoning beast passing by?"
He shook his head and paid it little mind.
After all, this was an offshore forbidden zone shrouded in mist year-round. Strange weather phenomena were perfectly normal here.
His priority now was to continue developing "Black Iron: Senju Hundred Rending Fists."
Kenya sat cross-legged again and turned his focus inward.
As his training deepened.
The blood and vital energy within him circulated faster and faster, nearly spiraling out of control.
His Armament Haki and Wood Release Cells collided and fused frantically.
Each fusion brought the agony of tearing muscles and the pleasure of being born anew.
This special training at the very edge of his limits also left Kenya in a strange mental state of intense tension and extreme excitement.
"Again!"
Kenya's eyes snapped open, a trace of madness flashing in their depths.
"Break through my limits!"
He threw his head back and let out an inhuman roar.
In that instant.
The overabundant power within him, with nowhere to escape, seemed to finally find an outlet.
But that outlet was not a physical breakthrough.
It was... his spirit!
Bzzz-!
Without warning, a strange pulse rippled violently outward from Kenya.
This was neither a Chakra blast nor a mere storm of air.
It was an invisible, terrifying will filled with absolute dominion!
The air seemed to thicken at that moment.
Crackle-!
Several eerie bolts of dark red lightning burst out of thin air around Kenya!
These bolts had neither heat nor substance, yet carried a pressure that made souls tremble.
They danced around Kenya, illuminating his bronze body until he resembled a demon god returned from hell.
"This is..."
Kenya stared at the dark red lightning coiling around his fingertips, his pupils contracting sharply.
He felt his will undergo a kind of elevation at that moment, as though he could control the life and death of every living creature around him.
"Conqueror's Haki?!"
The moment that thought arose.
The terrifying will suppressed within him erupted completely, like floodwaters bursting through a dam!
Boom-!!!
The invisible storm of will became a seemingly tangible shock wave of spiritual force.
It swept wildly in every direction with earth-shattering momentum!
This eruption of Conqueror's Haki was thousands of times more violent than the unconscious, embryonic form he had unleashed against the Root ninja!
In just an instant.
The dark red spiritual storm swept across the entire deserted island, even reaching the waters offshore.
In the jungle at the edge of the deserted island.
A giant saber-toothed tiger over five meters long was tearing into its prey.
When that invisible pulse swept through its body.
The ferocious beast, which could rightly be called the island's overlord, abruptly froze.
Its vertical pupils, filled with savage ferocity, instantly flooded with utter terror.
"Awooo..."
The saber-toothed tiger let out a whimper like a beaten puppy.
The next second.
Its enormous body toppled over stiffly, eyes rolling back and foam spilling from its mouth as it passed out on the spot!
It was not just the saber-toothed tiger.
The fierce birds on the cliffs, the venomous snakes deep in the jungle, the giant crocodiles lurking in the swamps...
Even several enormous sea monsters roaming the coastal waters.
The instant they encountered this Conqueror's Haki.
Without a single exception!
Thousands upon thousands of beasts rolled their eyes back and fell unconscious, as though facing doomsday judgment.
The deserted island, once teeming with life amid the roars of beasts.
Fell into absolute, deathly silence at that moment.
Only the howl of the sea wind echoed across the empty island.
Meanwhile.
Inside the deserted island base's Black Iron Wood fortress.
Zabuza was carrying a log toward the wall when his heart suddenly lurched.
An indescribably terrifying pressure abruptly descended upon him.
"Wh... what is this feeling?!"
Zabuza's expression changed drastically.
He could barely breathe. His legs gave way, and he dropped to his knees with a thud.
The log on his shoulder crashed heavily to the ground, but he did not even notice.
Drenched in cold sweat, he raised his head and looked toward the island's central valley in terror.
It felt as though an invisible blade hung over his soul.
With a single thought from the other party, his soul would instantly be scattered!
This was not killing intent at all!
Killing intent could be resisted through training, but this crushing force of pure will left him unable to muster even the slightest thought of resistance!
"What on earth... is the boss doing?"
Zabuza gasped for breath, his entire body trembling slightly beyond his control.
Elsewhere.
Tsunade, who was handling administrative documents, also sprang from her chair.
Her beautiful eyes were filled with incredulous shock.
"What a terrifying Chakra fluctuation... no! This isn't Chakra!"
As a Super Kage Level powerhouse, Tsunade possessed exceptionally keen perception.
She immediately realized that the pulse sweeping across the island belonged to no known system of Ninjutsu!
This was pure spiritual pressure, domineering to the absolute extreme!
Even someone as powerful as Tsunade, the instant she felt this pressure.
Instinctively stiffened slightly, and even her heartbeat slowed for half a beat.
"This presence is coming from the central valley... it's Kenya!"
Tsunade took a deep breath and forcibly suppressed the trembling in her heart.
Her figure flashed, becoming a green afterimage as she sped toward the central valley.
When Tsunade reached the edge of the valley.
The sight before her left this widely experienced member of the Konoha Sannin utterly stunned.
The entire valley looked as though a devastating storm had swept through it.
Enormous rocks had been shattered by an invisible force.
And at the very center of the valley.
Kenya stood quietly amid the rubble, his upper body bare.
His eyes had turned an eerie dark red, without the slightest flicker of emotion.
All around him.
That heart-stopping dark red lightning continued to burst and snake about.
As though he were the sole, absolute ruler of this world!
That domineering aura of sovereignty over all made even Tsunade, his elder, feel an indescribable oppression.
"This brat's spiritual power has actually become this concentrated..."
Tsunade stared at Kenya in the center of that dark red aura.
Her mind went completely blank.
The Senju Clan's Wood Release was filled with vitality and acceptance.
But this power was filled with destruction and absolute dominion!
"This isn't the power of the Senju at all..."
Tsunade swallowed and murmured to herself.
"This is practically... a demon god."
