Besides this option, he has two other alternatives:
One option was to directly seal Kaguya Jinchūriki, and the other was to forcibly refine her into Six Paths Puppet.
However, both of these alternatives have significant drawbacks.
Sealing the Jinchūriki carries the risk of them going berserk at any time, while creating a puppet would prevent the full power of their immortality from being unleashed.
With Uchiha Xin relentlessly pressing forward, Hagoromo had no choice but to abandon the best option and forcibly seize Kaguya's body.
This is the only way out he can currently grasp.
The soul of Hagoromo had been nurtured in the Pure Land for a thousand years, becoming incomparably powerful and almost solidified and eternal.
The only thing he lacked was a physical body capable of fully bearing his terrifying power.
This is also the core reason why he is determined to seize Kaguya's body.
Previously, he allowed the Otsutsuki trio to appear, and even watched them being slaughtered by Uchiha Xin, without offering any assistance.
It wasn't that he didn't want to, but because he didn't have a complete physical body, he couldn't fully unleash his combat power.
"As long as I completely merge with this immortal body..."
With Hagoromo eyes tightly shut, Chakra within her body.
He is rapidly merging with Kaguya's physical body.
As the fusion progressed, his originally aged and blurry spiritual form began to fade rapidly.
Gray hair turns black, wrinkles are smoothed out.
His figure grew increasingly younger and more upright, and the aura emanating from him was steadily increasing at a terrifying rate.
The surrounding space, under the oppressive force of this aura, groaned incessantly.
Her physical appearance had completely transformed into that of Hagoromo in her youth, but the icy aura that belonged to Kaguya still lingered in the air.
The Nine-Tomoe Rinnegan in the center of his forehead was tightly closed.
The integration is not yet complete.
He needs more time.
Just as he was focusing on the crucial moment of integration.
"Laugh--!"
In the void ahead, a spatial portal radiating a blend of azure and purple-gold light was forcibly torn apart.
Uchiha Xin, hands in his pockets, expression indifferent, stepped out of the portal.
The extreme light emanating from his body illuminated this desolate alien space.
Hagoromo suddenly opened her eyes, her gaze filled with apprehension.
He understood.
The fact that Uchiha Xin is standing here unharmed means that the Otsutsuki trio is completely dead.
Moreover, the other party followed the indelible spatial marker and accurately tracked down this top-secret location.
"You arrived quite quickly."
Hagoromo gave a cold laugh, feigning composure.
He slowly stood up, looking down at Uchiha Xin, attempting to reason with him.
" Uchiha Xin, I admit you have some skills; even those three idiots from the Ōtsutsuki Main Family couldn't stop you."
"But do you think finding this place will change anything?"
"I have now mastered my mother's immortality, a power that is far beyond what a younger generation like you can contend with."
"If you retreat now, I might spare your life out of consideration for our shared lineage in the Shinobi World."
Hagoromo spoke arrogantly, as if victory was already assured.
He was trying to delay the last bit of time for physical fusion through this clumsy tactic of provocation and threats.
Uchiha Xin stood there, looking at him as if he were an idiot.
The Nine-Tomoe Tensei Rinnegan activated, instantly revealing the Chakra flow within Hagoromo's body.
"Old dog, you're about to die, what are you still pretending to be, acting all high and mighty?"
Uchiha Xin chuckled, his tone full of undisguised mockery.
"Delaying time?"
"The eye on your forehead isn't even open yet; your soul and body are still repelling each other."
"In your current half-dead state, you dare to shamelessly say you'll spare my life?"
With her thoughts exposed to her face, Hagoromo's expression instantly turned extremely ugly.
"Presumptuous!"
"Since you're so eager to die, I'll grant your wish!"
With Hagoromo furious roar, the Six Paths Chakra within his body erupted.
Uchiha Xin didn't give him a chance to continue rambling.
"You talk too much nonsense."
Uchiha Xin's eyes turned cold, and he made the first move.
He suddenly raised his right hand, his five fingers spread wide.
The Power of the Extreme Path within his body intertwined wildly with the Lightning Release Chakra.
"Ultimate Lightning Release: Divine Dragon!"
boom--!
A blinding, blazing white lightning bolt instantly illuminated the entire alternate dimension.
Accompanied by a deafening, violent dragon roar.
A colossal Thunderbolt dragon, a thousand meters long, roared forth from Uchiha Xin's palm.
This Thunder Dragon was formed entirely from the purest, most extreme form of Thunderbolt.
Purple-gold law patterns flowed across the dragon scales, radiating a terrifying power capable of destroying the world.
The Thunder Dragon opened its blood-red maw, tearing through the space in its path, and with an overwhelming aura, it hurtled straight towards Hagoromo.
Wherever the Thunderbolt struck, it carved a massive, bottomless canyon into the earth of the alternate dimension.
"What terrifying Lightning Release!"
Hagoromo's heart trembled violently as she sensed the deadly threat emanating from the Thunder Dragon.
With his still incompletely fused physical body, if he were to take this attack head-on, he would definitely be severely injured on the spot.
Even the process of possession can be forcibly interrupted.
At a critical moment.
The Hagoromo was no longer kept, and his hands were suddenly clasped together.
" Six Paths - Susanoo!"
Buzz!
The materialized Six Paths Chakra erupted from his body like a volcanic eruption.
In the blink of an eye, a giant Susanoo, hundreds of meters tall, rose from the ground.
This Susanoo is entirely a deep dark gold color, its surface covered with heavy Six Paths Armor.
It has two wings on its back and exudes an extremely ancient and heavy aura.
This is the ultimate defense unleashed by Hagoromo, combining the Six Paths Power with the power of the possessed body.
"Smash it for me!"
Hagoromo roared in fury.
The dark golden Six Paths Susanoo stretched out its enormous hands and firmly grasped the roaring, thousand-meter-long Thunderbolt dragon.
Rumble!
The raging Thunderbolt collided violently with the Six Paths Chakra, erupting into a blinding ball of light.
The Thunder Dragon struggled frantically, trying to tear apart Susanoo's defenses.
But the power of the Six Paths Susanoo is equally terrifying.
With the full force of the Hagoromo, Susanoo's hands suddenly tore outwards.
Click!
It was accompanied by a deafening explosion.
That terrifying thousand-meter-long Thunder Dragon was torn in two by the Six Paths Susanoo hands.
Lightning exploded across the sky, transforming into countless tiny arcs of electricity that dissipated into the void.
Hagoromo stood inside the crystal of the Six Paths Susanoo, panting heavily.
Although he blocked the attack, his Chakra was greatly depleted.
However, he had already achieved his goal.
This enormous Six Paths Susanoo not only withstood Uchiha Xin's attack,
It was like an impregnable fortress, firmly protecting him within.
"As long as I remain hidden Susanoo, I can safely complete the final fusion!"
Hagoromo's eyes turned crazed, and she continued to accelerate the fusion of their physical bodies.
Uchiha Xin, looking down at the giant, dark golden Susanoo, sneered.
