But Uchiha Xin merely raised his eyes.
"Super Shinra Tensei "
boom--!!!
An irresistible and terrifying repulsive force erupted from Uchiha Xin!
The golden sea of sand was forcibly blasted apart.
The sand wall, pressing in from all directions, seemed to have collided with an invisible wall of heaven, instantly swirling back.
The falling yellow sand was blasted high into the sky.
The churning quicksand below was pressed into a huge crater several kilometers in diameter.
The entire Sand Dimension shook violently.
Black Zetsu's voice changed from fright at the aftershock.
"How is this possible! He was able to unleash such power even within Mother's spatial dimension!"
Kaguya's expression grew even colder.
She did not back down.
It didn't stop.
The yellow sand scattered by the Super Shinra Tensei was frantically gathered again under her Chakra control.
These grains of sand, as if possessing a life of their own, densely re-coagulated into countless sand spears, sand chains, and sand hands.
They attacked simultaneously from high above, underground, and from all directions.
One layer breaks, and the next layer immediately fills in.
One wave is knocked away, and the next wave immediately follows.
Kaguya was clearly disregarding her own resources.
She would rather drain all the power of the entire Sand Dimension than let Uchiha Xin release Black Zetsu.
"That's really annoying."
Uchiha Xin frowned.
There's too much yellow sand.
This place is Kaguya's space. As long as she continues to control it, the sea of sand is endless and can never be completely destroyed.
And with Black Zetsu to be completely absorbed, if he were to be held back at this moment, Kaguya would definitely become even more frantic.
Uchiha Xin's pair of azure Tensei Rinnegan lit up.
Purple ripples spread across the underside of the eyes.
"Reincarnation - Space Freeze."
Buzz--!
An invisible Law of Space instantly spread out.
The yellow sand, which had been howling wildly, suddenly stopped in mid-air without warning.
The sand spears came to a stop.
The sand chains froze.
Even the quicksand surging up from beneath your feet seemed to be sealed inside transparent amber, completely solidified.
The world fell silent for a moment.
Hundreds of millions of grains of sand settled around Uchiha Xin, with the closest ones being less than an inch away.
But this one inch has become an insurmountable chasm.
Kaguya's eyes widened.
" Space Freeze again..."
She gritted her teeth, her face full of anger.
"What kind of monster have those eyes of yours!"
Uchiha Xin did not answer.
He clenched his right fist suddenly.
The devouring power in his palm surged instantly.
Black Zetsu's last remaining bit of willpower finally gave way.
"No! No! I can't die!"
"Mother--!"
A piercing scream echoed through the Sand Dimension.
The next moment, Black Zetsu's voice abruptly stopped.
That jet-black will was completely absorbed into Uchiha Xin's body by the devouring power in his palm, leaving not a trace behind.
[Ding! Absorption complete.]
A system notification sounded in Uchiha Xin's mind.
[Detected that the host has successfully absorbed Otsutsuki Kaguya's will and transformed into Black Zetsu.]
[Special primordial energy has been transformed.]
[Proficiency with the Tensei Rinnegan has been greatly increased.]
[The current progress of my Dōjutsu evolution has exceeded the critical threshold.]
[Congratulations, host! Your Tensei Rinnegan has officially entered the first stage of evolution.]
Uchiha Xin's heart skipped a beat.
Almost at the same moment the system notification appeared, his eyes suddenly changed.
Originally, those eyes that combined features of the Tenseigan and Rinnegan,
It already possesses a deep blue radiance like a starry sea, and its pupils also have purple ripple patterns and a tai chi symbol.
But now.
Three jet-black Tomoe slowly emerged from those concentric rings of patterns.
Three Tomoe are imprinted on the ring-shaped patterns on the outer side of the pupil, slowly rotating as the pupil's energy flows.
The azure radiance did not disappear.
The reincarnation patterns have not disappeared.
The yin-yang shaped pupils did not disappear.
But after these three Tomoe appeared, the oppressive feeling in his eyes instantly increased to a whole new level.
That's no longer just about fused Dōjutsu.
It's more like some kind of truly complete Eye of God.
Kaguya stared intently into Uchiha Xin's eyes, her face, which had been contorted with extreme anger, now showing barely suppressed shock.
" Tomoe..."
"Your eyes can actually continue to evolve?"
Uchiha Xin himself was somewhat surprised.
He asked in his mind:
"System, what's going on?"
"Didn't my Tensei Rinnegan already fully fuse a long time ago? How come I have three more Tomoe now?"
The system was silent for a moment, then issued a notification with a hint of arrogance.
[ The Tensei Rinnegan that the host previously possessed was only in its original form.]
[The so-called original form is merely the completion of basic fusion and does not reveal the true appearance of this Dōjutsu.]
[After absorbing the primordial will of Kaguya contained within Black Zetsu, the host's proficiency in Dōjutsu has greatly increased, successfully unlocking the true form.]
[Current form: Mitsudomoe Tensei Rinnegan.]
Uchiha Xin raised an eyebrow.
"True form?"
That's right.
The system's voice continued to play.
[ The Tomoe is not an additional mutation, but rather one of the core characteristics that the Tensei Rinnegan.]
This Dōjutsu has room for multiple stages of evolution.
[The host has not yet completed the final transformation, but has entered the first stage, unlocking the true form of this Dōjutsu.]
Uchiha Xin understood.
The previous Tensei Rinnegan was just a rudimentary form that had just been fused together.
The addition of the three Tomoe marks the true beginning of the eyes' proper development.
He couldn't help but complain in his mind:
"So, I've been using the youth version all along?"
The system immediately snorted coldly.
[Please be mindful of your wording, host.]
[Furthermore, this system solemnly reminds you that the host is currently still in a state of high-intensity combat.]
[Being distracted by chatting with the system during battle is an extremely dangerous act.]
[If the host is struck by Otsutsuki Kaguya as a result, this system will not be held responsible.]
Uchiha Xin twitched the corner of his mouth.
"You're quite good at shifting blame."
The system replied with an air of arrogance.
[This system is only providing a friendly reminder.]
In the brief moment that Uchiha Xin was exchanging words with the system...
Otsutsuki Kaguya finally came to her senses.
Black Zetsu is gone.
The one that had accompanied her for over a thousand years, remaining loyal even after she was sealed away.
The child who hid in the shadows of the Shinobi World, working tirelessly to help her regain her freedom, is gone.
Black Zetsu ordinary subordinate.
It is not an embodiment of ordinary will.
For Kaguya, he was the only person who had stood by her side through the long years since she was betrayed by her two biological sons.
It was Black Zetsu who altered the stone tablet.
It was Black Zetsu who guided the descendants of Indra.
It was Black Zetsu who instigated a war that lasted a thousand years in the Shinobi World.
It was Black Zetsu, at the last moment, personally rescued her from the seal.
But now.
It was absorbed by Uchiha Xin right in front of her.
Completely disappeared.
Kaguya lowered her head, her wide sleeves trembling incessantly.
She didn't speak immediately.
