That was—the Great Serpent's heart!
It had actually seen Naruto kick back from the moon with a Night Guy and preemptively separated its most important heart!
1500 meters deep underground, the true command center of the Monster Association.
A woman with long blue-purple hair, wearing black-rimmed glasses and a graceful figure, lay slumped on a sofa, bleeding from all seven orifices, her face as pale as paper.
She was Psykos, the true body controlling Gyoro-Gyoro.
And also the mastermind behind the Monster Association.
Just now, she had remotely sensed the god-like battle above through her psychic powers, and the Great Serpent's ultimate defeat and the world-destroying power had caused her immense backlash.
"Lost—even the god-like Great Serpent—lost—" Her eyes were filled with despair and madness, "What exactly is that human monster—"
"Like Tatsumaki—no—even more terrifying than that bitch!"
Just then, the dark red mass of flesh, as if possessing a will of its own, penetrated the rock wall of the secret room and appeared before Psykos.
"Psy—kos," a faint yet undeniably authoritative thought directly entered her mind.
"Gr-Great Serpent?!" Psykos looked at the pulsating mass of flesh before her in shock.
"Give me your body—your power—dedicate it to me—" The mass of flesh emitted waves of both temptation and compulsion, "Only by merging—can we resist that existence—only then can we achieve—true transcendence—!"
A trace of struggle flashed across Psykos's face, but it was quickly replaced by a deeper ambition and the madness born of despair.
She craved power, craved transcendence, craved to trample all humans underfoot!
Now, the only opportunity was right before her eyes.
"Hehe—hahaha—Alright! Lord Great Serpent! Let us become one! Let us become new gods!"
Psykos spread her arms, her powerful psychic abilities no longer guarded, actively embracing the mass of flesh!
The dark red mass of flesh, like a living creature, lunged at Psykos, rapidly merging into her body.
Psykos let out a shriek of pain and pleasure intertwined, and her body began to undergo terrifying mutations.
Her blue-purple long hair danced wildly without wind, her body's muscles unnaturally swelled and twisted, dark patterns similar to the Great Serpent's appeared on her skin, and her powerful psychic abilities began to forcibly merge with the violent energy of the monster cells.
An malice far more sinister, more twisted, and more immense than the Great Serpent's, like an awakened ancient fiend god, erupted from the secret room 1500 meters below the ground!
"Boom!"
A blue-black interwoven energy pillar broke through layers of rock walls, directly piercing the surface!
Within the pillar of light, a hideous figure floated up, standing proudly above the ruins of Z-City.
That was Psykos's form after completely merging with the Great Serpent's core—Psykos-Orochi!
Her lower body was a long, winding serpent's torso, covered in scales as dark as an abyss, while her upper body retained a humanoid form, but her face was not Psykos's, but rather an armored monster, with layers of strange wings growing on her back, and four arms extending from her ribs, appearing slender yet filled with destructive power, and her hands grasped a pitch-black spear formed from pure dark energy, its tip constantly tearing the surrounding space, emitting ominous fluctuations.
"Do you feel it? This power that transcends the old gods!" Psykos-Orochi's voice, a mixture of Psykos's sharp tone and the Great Serpent's low growl, echoed between heaven and earth, "The Great Serpent's defeat was merely a sacrifice offered for the birth of my perfect form!"
She spread her four arms, and her immense psychic and monster energy, like invisible giant hands, reached out towards the vast Pacific Ocean.
The next moment, a sight that shocked the entire world occurred—the distant sea level suddenly rose, an immeasurable amount of seawater was pulled up from its roots, forming a super wall of water that connected heaven and earth, its height even exceeding the stratosphere!
This truly overwhelming tsunami transformed into a world-ending torrent capable of scouring the continental shelf!
"Whoosh!"
Just then, Naruto arrived from the other side of the planet, and upon seeing the towering tsunami rising from the Pacific Ocean, his face instantly changed dramatically.
"This tsunami is enough to destroy the world!"
Above Psykos-Orochi's forehead, Psykos's figure materialized, taunting Naruto: "Naruto, you still dare to show yourself?"
"You've exhausted your power fighting the serpent, what do you have left to fight me?"
"Exhausted my power? Is that so—"
"Then you'd better open your eyes and see if I've exhausted my power!!"
"Yin Seal: Release!"
At this moment, Naruto finally unleashed his last trump card without hesitation.
The third vertical eye on his forehead, which had opened with the Rinnegan, closed again, becoming smooth and flat, instead revealing a diamond-shaped mark that glowed brightly, an indescribably vast amount of Chakra and pure life force poured into his somewhat dry body like sweet rain, rapidly repairing damage and replenishing consumption.
In the blink of an eye, Naruto, who had almost "burned out," returned to his peak state.
"Take-Mikazuchi Mode: Death Realm—Reactivate!!"
"Boom!"
Even more violent and profound blood-red steam than when he fought the Great Serpent's true body erupted from Naruto's body like a volcanic explosion!
This time, the blood-red steam not only contained the destructive energy of the Eight Gates burning life, but also integrated the massive Chakra and life force provided by the Yin Seal as support, making it more sustained and powerful.
One must know—this was five hundred million years of life force.
Azure-white lightning danced in the steam, emitting a shriek that vibrated space, and the blood-red giant dragon phantom behind Naruto almost solidified, with the cold Rinnegan ripples in its dragon eyes!
Naruto merely stood there, yet he exuded a world-destroying aura that pressed down on this heaven and earth—no, the entire Earth—as if it could no longer bear it.
"Impossible! How can you still have power left? It's impossible, you must be burning your life force, forcibly activating this state, you are courting your own destruction!"
Psykos-Orochi shrieked, launching the first attack.
She waved her hands, and countless blue-black energy blades, fused with psychic and monster energy, appeared out of thin air, slashing at Naruto like a destructive storm, each one capable of easily cutting through the Earth's highest and longest mountain ranges!
"Ultimate—Shinra Tensei!!"
Naruto let out a low roar, and the terrifying repulsive force, amplified by the Yin Seal and strengthened by the Eight Gates: Take-Mikazuchi Mode, expanded spherically, no longer just a simple push, but carrying the will to crush everything!
The storm of blue-black energy blades disintegrated and vanished the moment they touched the repulsive field.
Not only that, even the world-ending tsunami, which was sweeping across the sky from a great distance, was repelled by the Super Shinra Tensei, turning into a sky full of rain, refilling the exposed Pacific Ocean seabed, which was large enough to accommodate all continents.
